Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression
(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, Ahmet
In the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.

The antioxidant and anti-apoptotic potential of Pleurotus eryngii extract and its chitosan-loaded nanoparticles against doxorubicin-induced testicular toxicity in male rats
(Wiley, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Acay, Hilal; Yıldırım, Ayfer
This study was conducted to evaluate the protective role of Pleurotus eryngii extract (PE) and Pleurotus eryngii extract-loaded chitosan nanoparticles (PE-CSNP) against doxorubicin (DOX)-induced testicular toxicity in rats. Male rats were divided into six groups: control (DMSO/ethanol), PE (200 mg/kg PE), PE-CSNP (30 mg/kg PECSNP), DOX (10 mg/kg DOX, a single dose, i.p), DOX+PE (10 mg/kg DOX+200 mg/ kg PE) and DOX+PE-CSNP (10 mg/kg DOX+30 mg/kg PE-CSNP). PE and PE-CSNP were administered by oral gavage every other day for 21 days. DOX-treated rats showed histopathological impairment compared with the control group. There was an increase in the apoptotic index, caspase 3 (CASP3), BCL2-associated X apoptosis regulator (BAX), dynamin-related protein 1 (DRP1) expression and total oxidative status (TOS) in the DOX group, while mitofusin-2 (MFN2), total antioxidative status (TAS) and serum testosterone levels of the DOX group reduced when compared with the other groups. PE and PE-CSNP treatments provided significant protection against DOX-induced oxidative stress by reducing TOS levels and increasing TAS levels. CASP3, BAX, apoptotic index and DRP1-MFN2 expressions were restored by PE and PE-CSNP. However, the PE-CSNP showed higher antioxidant and anti-apoptotic efficacy compared with PE. Thus, our results provide evidence that CSNP and PE could synergistically have a potent antioxidant and anti-apoptotic therapy against DOX-induced testicular damage in male rats.

Carbamazepine-induced renal toxicity may be associated with oxidative stress and apoptosis in male rat
(Taylor & Francis Online, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Etem Önalan, Ebru
Carbamazepine (CBZ) is the antiepileptic drug used in epilepsy and some psychiatric disorders. Besides its widely used, many adverse effects have been reported including hematotoxicity, hepatotoxicity, endocrine disorders, and testicular damages due to oxidative stress. However, the role of CBZ on renal toxicity is not fully known. In this study, we attempted to explain the connected mechanisms by focusing on the metabolism of CBZ-induced renal toxicity in rats. Twenty male Wistar-Albino rats were randomized into 2 groups (n = 10); control (1 mL/day distilled water, orally) and CBZ (25 mg/kg/day CBZ, orally) groups. After 60 days, TAS (total oxidant status) and TOS (total oxidant status) levels, histopathological features, some genes involved in apoptosis, 8-hydroxy-2-deoxyguanosine (8-OHdG) activity, and apoptotic cells were assessed of kidney tissue. The oxidative stress index (OSI) was measured from TAS and TOS levels. TOS levels and OSI significantly increased, while TAS levels decreased in the CBZ group relative to the control group. Histopathological observations, Caspase-3 (Casp3), Poly [ADP-ribose] polymerase-1 (PARP-1), 8-OHdG immunoreactivities, and apoptotic cells markedly raised in the CBZ group compared with the control group. Also, mRNA expression of Cytochrome c (Cytc) and CASP3 significantly increased in the CBZ group compared to the control group. In conclusion, long-term use of CBZ may promote renal damage in rats by inducing oxidative stress and apoptosis.

Chronic effects of maternal tobacco-smoke exposure and/or α-lipoic acid treatment on reproductive parameters in female rat offspring
(Taylor & Francis Online, 2020) Erdem Güzel, Elif; Nalan Kaya, Ahmet Tektemur, Nazife Ulker, Ahmet Yardimci, Ramazan Fazil Akkoc, Sinan Canpolat & Ibrahim Enver
Prenatal tobacco-smoke exposure negatively affects the reproductive functions of female offspring and oxidative stress plays a major role at this point. Alpha-lipoic acid (ALA), well known as a biological antioxidant, has been used as a nutritional supplement and as a therapeutic agent in the treatment of certain complications during pregnancy. We aimed to investigate the effects of maternal tobacco-smoke exposure and/or ALA administration on puberty onset, sexual behavior, gonadotrophin levels, apoptosis-related genes, apoptotic cell numbers and oxidative stress markers in the adult female rat offspring. Sprague-Dawley rats were divided into four groups; control, tobacco smoke (TS), TS+ALA and ALA groups. Animals were exposed to TS and/or ALA for 8 weeks before pregnancy and throughout pregnancy. All treatments ended with birth and later newborn female rats were selected for each experimental group. The experiment ended at postnatal day 74-77. Maternal tobacco smoke advanced the onset of puberty in the female offspring of the TS group (p < 0.05). In all treatment groups; the mean number of anogenital investigations and lordosis quality scores showed a decline, serum luteinizing hormone levels significantly increased (p < 0.05) and several histopathological changes in ovaries were observed compared to the control group. In addition, an increase in apoptotic marker levels and apoptotic cell numbers was detected in the ovaries of all treatment groups. Decreased TAS and increased TOS levels were detected in all treatment groups compared to control. These findings suggested that maternal tobacco smoke and/or ALA administration may be leading to the impaired reproductive health of female offspring. Abbreviations: ALA: alpha-lipoic acid; LH: luteinizing hormone; FSH: follicle-stimulating hormone; TAS: total antioxidant status; TOS: total oxidant status; Apaf1: apoptotic protease-activating factor 1; Casp3: caspase 3; Casp9: caspase 9; CF: cyst follicles; 4-HNE: 4-Hidroxynonenal; 8-OHdG: 8-hydroxydeoxyguanosine; TUNEL: terminal deoxynucleotidyl transferase-mediated deoxyuridine-biotin nick end labeling; ROS: reactive oxygen species; GnRHR: gonadotropin-releasing hormone receptor; HPG: hypothalamic-pituitary-gonadal; AMPK: AMP-activated protein kinase; ELISA: enzyme-linked immunosorbent assay; cDNA: complementary DNA; qPCR: quantitative real-time PCR; FC: follicular cysts; PF: primary follicle; SF: secondary follicle; GF: graafian follicle; CL: corpus luteum; DF: degenerated follicle; AF: atretic follicle.

Chronic Maternal Tobacco Smoke Exposure and/or Alpha-Lipoic Acid Treatment Causes Long-Term Deterioration of Testis and Sexual Behavior in Adult Male Rats
(Elsevier, 2020) Yardimc, Ahmet; Ramazan Fazil Akkoc, Ahmet Tektemur, Nazife Ulker, Nalan Kaya Tektemur, Elif Erdem Güzel, Sinan Canpolat, Ibrahim Enver Ozan
Background: Tobacco use during pregnancy is known to have several negative effects on the offspring's reproductive health in the long term. The use of alpha-lipoic acid (ALA) as a dietary supplement during pregnancy has increased greatly in recent years and has been known to have positive effects on various pregnancy outcomes including miscarriage, diabetic embryopathy, preterm delivery, and congenital malformations. Aim: To evaluate the effects of tobacco smoke exposure (TSE) on sexual behavior, reproductive parameters, and testicles in adult male rats and to reveal the possible role of ALA administration on these parameters. Methods: Pregnant rats (n = 7 per group) were treated with tobacco smoke (TS), ALA (20 mg/kg), and TS + ALA for a total of 11 weeks. The following parameters were compared with 8 control rats: puberty parameters, sexual behavior; levels of serum gonadotropins and testosterone, total antioxidant status, and total oxidant status; the expression of the apoptotic protease-activating factor-1 and caspase 9 mRNA levels in the testis; and assessment of immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick end labeling assay of testis. Main Outcome Measure: Sexual behavior, changes in puberty parameters, and hormonal and genetic alterations were the outcomes analyzed in this study. Results: Maternal TSE caused a significant decrease in the number of intromissions compared to the control group. Similarly, ALA decreased erectile function in sexual behavior by decreasing the number of intromissions and intromission ratio in the ALA group compared to the control group. In addition, TSE and ALA treatment caused an impairment of some consummatory sexual behaviors. Also, in parallel with this inhibitory effect, the age of pubertal onset was significantly delayed in the TS + ALA group compared to other groups. Also, histopathological changes in testicular tissue, oxidative stress markers, apoptotic index, and mRNA levels of apoptosis-related genes increased in all treatment groups. Clinical Implications: The use of ALA and/or tobacco products during pregnancy may adversely affect the reproductive health of male newborns in the long term. Strengths & Limitations: To the best of our knowledge, this study is the first to show the effects of maternal ALA treatment and/or TSE on the sexual behavior and reproductive parameters in male rats; however, the study is based on an animal model, and the present findings partially reflect the characteristics of human sexual behavior. Conclusion: Maternal TSE and/or ALA treatment may impair sexual behavior in adulthood in male rats because of testicular damage caused by oxidative stress during gonadal development.

The combination of N-acetylcysteine and cyclosporin A reduces acetaminophen-induced hepatotoxicity in mice
(Ultrastructural Pathology, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Gül, Mehmet; Tektemur; Özcan Yıldırım, Sena; Kavak Balgetir, Merve; Ozan Kocamüftüoğlu, Gonca; Yalçın, Tuba; Ozan, & İbrahim Enver
Acetaminophen (APAP)-induced hepatotoxicity is the most common cause of acute liver failure in worldwide. N-acetyl cysteine (NAC) is used as the APAP antidote. Cyclosporin A (CsA) is suppressed mitochondrial damage by binding cyclophilin, a mitochondrial pore transport component. The study aimed to evaluate the effects of NAC, CsA, and NAC+CsA treatments on APAP-induced hepatotoxicity in mice. Mice were randomly divided into five groups (n = 6). 400 mg/kg/ip/single dose APAP, 1200 mg/kg/i.p/single dose NAC and 50 mg/kg/i.p/single dose CsA were performed. Light and electron microscopic alterations were investigated in liver samples. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and liver glutathione (GSH) were analyzed. 3-nitrotyrosine and cytochrome c immunoreactivities were evaluated in liver tissue. Here, we found that APAP leads to histopathological and ultrastructural changes in mice liver. Also, APAP increased cytochrome c and 3-nitrotyrosine immunopositive staining. Besides, a significant decrease in liver GSH and an increase in serum AST and ALT levels were detected in the APAP group. Interestingly, NAC+CsA treatment improved histological alterations, cytochrome c, and 3-nitrotyrosine immunoreactivities and liver GSH, serum AST/ALT levels caused by APAP. We suggest that the combination of NAC and CsA reduces acetaminophen-induced hepatotoxicity in mice.

(Sage Journals Home, 2023) Bıçak Ayık, Derya; Can, Gülbeyaz
Objectives: This experimental randomized-controlled study was performed to define the efficacy of auricular acupressure (AA) in the management of constipation developing in palliative care patients. Methods: According to the pre-prepared randomization list, 44 patients were included in the experimental group and 46 patients were included in the control group. Routine clinical treatment and care implementation were maintained in the patients in both groups. AA was performed for 4 weeks in patients in the experimental group. During the study, to determine the complaints of the patients regarding constipation, the information in the daily patient chart was examined at least 5 times by interviewing with the patient/patient's relative in the clinic and/or via phone call, and the results were recorded in the patient chart and data collection forms. The independent variable of the study is AA application, and the dependent variables are constipation and quality of life. Results: It was determined that there was no statistically significant difference between the daily defecation frequency of the 2 groups during the first 11 days. However, after the 12th day, the daily stool frequency of the experimental group was higher compared to the control group and this difference obtained between the 2 groups was statistically significantly different. AA was effective in decreasing laxative use. Conclusion: This intervention increased stool frequency, reduced physical and psychosocial symptoms, anxieties, and improved stool satisfaction and it was an effective approach to improving the quality of life. It is recommended that the daily use of AA should be evaluated. The healthcare providers including nurses, patients, and patient relatives should be trained regarding AA.

The effect of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students, descriptive cross-sectional research study
(Nurse Education Today, 2021) Yaşar, Beril Nisa; Kaya, Yunus; Arslan, Sevda; Erbaş, Atiye; Küçükkelepçe, Gürhan Erkuş
Background: Factors affecting intercultural sensitivity and care are becoming an increasingly important issue due to ethnic diversity. Nurses play a crucial role in care and therefore should keep up with this trend and improve their intercultural sensitivity. Objective and design: This descriptive cross-sectional study investigated the effects of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students. Methods and participants: Data were collected using a demographic characteristics questionnaire and the Intercultural Sensitivity Scale, Generalized Ethnocentrism Scale, and Moral Sensitivity Scale. The sample consisted of 1343 nursing students. The Pearson correlation coefficient was used to determine correlations between scale scores. Multiple linear regression was used to determine the effects of ethnocentrism, moral sensitivity, and demographic characteristics on intercultural sensitivity. Results: Intercultural sensitivity was found to be negatively correlated with ethnocentrism and positively correlated with moral sensitivity. Ethnocentrism predicted intercultural sensitivity more than moral sensitivity. Ethnocentrism and moral sensitivity explained 16.8% of the total variance of intercultural sensitivity. However, ethnocentrism affected intercultural sensitivity more than moral sensitivity did (beta = −0.406). Conclusion: Nursing education should adopt strategies to reduce ethnocentrism by helping students develop cultural competence and intercultural sensitivity. Such education can equip nurses to provide higher quality care to patients of different cultural backgrounds.

The Effect of Frailty Levels of Older Individuals on Their Mental Well-Being and Depression Levels
(Wiley, 2024) Isik, Kevser; Ayik, Derya Bicak; Cengiz, Zeliha
Background: Frailty has become an important public health issue. This study was conducted to determine the effect of frailty levels of older individuals on their mental well-being and depression levels. Methods: This descriptive cross-sectional study was conducted with a total of 325 older individuals aged 60 years and over. A demographic questionnaire form, the FRAIL Frailty Scale, the Warwick-Edinburgh Mental Well-Being Scale, and the Geriatric Depression Scale-Short Form were used to collect data. Data were evaluated using the SPSS 25.0 package program. Number, percentage, mean, standard deviation, Chi-square, correlation, and multiple regression analyses were used. Results: The mean age of the older individuals was 69.56 +/- 7.75 years, and the variables of age, education level, income status, the person they were living with, regular medication use, forgetting to take medication, urinary incontinence, hospitalisation, and accidents were found to affect both frailty and depression (P < 0.05). There was a positive correlation between frailty and depression (r: 0.460, P < 0.001) and a negative correlation between mental frailty and well-being (r: -0.391, P < 0.001). Socio-demographic variables, depression, and mental well-being had a 40% effect on frailty (P < 0.001). Conclusion: Depression status and mental well-being level are related to frailty, so negativity in one of them negatively affects the other. In line with these results, it is recommended to determine the level of depression and mental well-being of older individuals with high risk of frailty, and according to the results of the research, to provide care and support regarding the predictors affecting frailty.

Effects of Concomitant Use of N-Acetylcysteine and Cyclosporine a on Acetaminophen-Induced Acute Kidney Injury in Mice
(Agricultural Research Communication Centre, 2024) Kocamueftueoglu, Gonca Ozan; Tektemur, Nalan Kaya; Guzel, Elif Erdem; Tektemur, Ahmet; Ozan, Ibrahim Enver
Background: Acetaminophen (APAP), a commonly used analgesic, causes acute kidney injury (AKI) in overdose although it is rare. Mitochondrial dysfunction plays a major role in the pathophysiology of renal damage, although the exact molecular mechanism is unknown. This study aimed to evaluate the potential therapeutic effect of cyclosporin A (CsA), a mitochondrial membrane permeability Methods: Male BALB/c mice were divided into Control, APAP, APAP+NAC, APAP+CsA and APAP+NAC+CsA groups (n=6). A single dose of APAP (400 mg/kg) was administered intraperitoneally. All other treatments (1200 mg/kg NAC, 50 mg/kg CsA) were performed intraperitoneally 3 h after APAP administration. All animals were decapitated and blood samples and kidney tissue samples were collected for evaluation. Serum creatinine (Cr) and blood urea nitrogen (BUN) levels were measured. The kidney tissue 8-hydroxydeoxyguanosine (8-OHdG), cytochrome c (Cytc) and 3-nitrotyrosine (3-NT) levels and cytochrome c (Cytc) expressions were determined. Result: Increased Cr and BUN levels, histopathological examinations and expressions of 8-OHdG, 3-NT and Cytc were detected in the APAP group. Combined NAC+CsA treatment sufficiently reversed oxidative stress, serum Cr and BUN levels and histopathological alterations induced by APAP. Moreover, cytc levels and renal tubular injury were remarkably reduced by combined drug treatment compared to the APAP+NAC group. These data suggest that the therapeutic effect of combined NAC+CsA treatment in mice with APAP-induced nephrotoxicity can be related to the combination of the antioxidant effect of NAC and the mitochondrial MPTP inhibitor effect of CsA.

This study aims to determine contraceptive intentions of pregnant women in the third trimester. This cross-sectional study was conducted at a training and research hospital in Mardin province between March 2023 and May 2023. In total, 253 pregnant women who had the ability to communicate in Turkish and agreed to participate were included in the study. Data were collected through face-to-face interviews using a survey and the Contraceptive Intent Questionnaire (CIQ). The average age of the participants was 28.87 ± 5.35 with 30.8% of them holding a secondary school degree. It was found that there was a statistically significant difference in terms of CIQ score between categories of the following descriptive variables: education level, husband's/partner's education level, fertility plan, receiving family planning counseling during pregnancy, and paying for the contraceptive methods used (P = .046, P = .013, P < .001, P = .008, and P < .001 respectively). It was determined that pregnant women who had not received family planning counseling during pregnancy and paid for the contraceptive method had higher contraception intention.
Evaluation of Nurses' and Midwives' Knowledge and Attitudes Towards Recognizing Violence Against Women
(Womens Health & Action Research Centre, 2024) Donmez, Ayseguel; Yesil, Yesim
The study was cross-sectional research that surveyed 410 nurses and midwives from March 2020 to March 2021 in Turkey. The aim of this study was to evaluate the knowledge and attitudes of nurses and midwives towards recognizing violence against women. The "Scale for Nurses' and Midwives' Recognition of the Symptoms of Violence against Women" were used. The average total scale score was 20.3 +/- 3.2. The score of participants who are receiving postgraduate education, working in the field of gynaecology and obstetrics, and considering intervention as a professional responsibility when encountering a woman who has experienced violence was found to be significantly higher than the other groups (p<.05). It is important for midwives and nurses to be aware of signs of violence to identify violence against women. Providing education to midwives and nurses regarding signs of violence against women will contribute to the recognition, prevention, and awareness of violence.

Hesperetin may alleviate the development of doxorubicin-induced pulmonary toxicity by decreasing oxidative stress and apoptosis in male rats
(Elsevier, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan
Doxorubicin (DOX) is one of the most widely used chemotherapeutic agents. However, it causes pulmonary toxicity which decreases its clinical use in human cancer therapy. The present study was undertaken to obtain an insight into the potential protective effect of hesperetin (HES) against doxorubicin-induced pulmonary toxicity in rats. The animals were divided into 4 groups with 7 rats per group. The experimental treatments were as follows: Control, DOX, DOX + HES, and HES groups. DOX was administered at the dosage of 15 mg/kg i.p for a single dose. HES was administered at the dosage of 50 mg/kg by oral gavage every other day. After 28 days, biochemical parameters, oxidative stress status, histopathological changes, apoptosis-related genes and apoptotic index (AI) were examined of lung tissue. Histopathological changes, Poly [ADP-ribose] polymerase 1 (PARP-1), Caspase-3 (Casp3), Cytochrome c (Cytc), apoptosis-related genes, and AI significantly increased in the DOX group relative to the control group. Malondialdehyde (MDA) significantly increased, while superoxide dismutase (SOD) and glutathione peroxidase (GPx) decreased in the DOX group relative to the control group. However, histopathological findings, MDA, AI, and PAPR1, Casp3 protein expression, mRNA expression of Cytc significantly decreased, while SOD, GPx increased in the DOX + HES group relative to the DOX group. These results attested HES might be a potential agent for the treatment of DOX-induced pulmonary toxicity.

The investigation of effect of alpha lipoic acid against damage on neonatal rat lung to maternal tobacco smoke exposure
(ELSEVIER SCIENCE BV, 2018) Erdem Güzel, Elif; Kaya, Nalan; Ozan, Gonca; Tektemur, Ahmet; Dabak, Durrin Özlem; Ozan, İbrahim Enver
This study was carried out to determine the changes in the lungs of the rat pups exposed to tobacco smoke during pregnancy period and to investigate the protective effects of alpha lipoic acid, which is administered during pregnancy, on these changes. Spraque-Dawley female rats were divided into four groups: control, tobacco smoke (TS), tobacco smoke + alpha lipoic acid (TS + ALA) and alpha lipoic acid (ALA). The rats in control group were untreated. Rats were exposed to TS twice a day for one hour starting from eight weeks before mating and during pregnancy. 20 mg / kg of ALA was administered to rats. On 7th and 21st days 7 of the pups from each group were decapitated. Histological, morphometric, biochemical and quantitative real-time RT-PCR analyzes were performed. Histopathological and biochemical changes were observed in TS group. While a significant decrease was observed both in SP-A and VEGF immunoreactivities and mRNA levels, caspase-3 immunoreactivity and TUNEL positive cells were increased in TS group. It is suggested that prenatal TS exposure leads to morphological and histopathological changes on lung development by causing oxidative damage in lungs of neonatal rats and the maternal use of ALA can provide a limited protective effect on the neonatal lung development against this oxidative stress originating from TS. Although pregnant women are increasingly aware on health risks of smoking, environmental tobacco smoke exposure is still a widespread problem. For this reason, it is thought that this damage can be partially reduced by some antioxidant supplements in pregnancy.
Investigation of the effects of Alfa lipoic acid on changes in maternal rat kidney caused by tobacco smoke exposure in pregnancy [Gebelikte Tütün Dumani Maruziyetinin Anne Siçan Böbrek Dokusunda Meydana Getirdigi Degişiklikler Üzerine Alfa Lipoik Asitin Etkilerinin İncelenmesi]
(Ataturk Universitesi, 2019) Erdem Güzel E.; Kaya N.; Ozan Kocamüftüoglu G.; Dabak D.Ö.; Temizer Ozan P.S.; Ozan I.E.
Çalışmada gebelikte tütün dumanına maruz kalan anne sıçanların böbrek dokusunda meydana gelen histopatolojik sonuçlar üzerine Alfa lipoik asitin etkilerinin deneysel olarak araştırılması amaçlandı. 28 adet dişi Sprague-Dawley cinsi sıçan kullanıldı. Gebe sıçanlar; Kontrol grubu, Tütün dumanı (TD) grubu, Tütün dumanı + Alfa lipoik asit (TD+ALA) grubu ve Alfa lipoik asit (ALA) grubu olmak üzere rastgele dört eşit gruba ayrıldı. TD ve TD+ALA grubundaki sıçanlar çiftleşmeden önce sekiz hafta ve gebelik süresince günde iki saat tütün dumanına maruz bırakıldı. TD+ALA ve ALA grubundaki sıçanlara ise çiftleşmeden önce sekiz hafta ve gebelik süresince gün aşırı gavaj yolu ile 20 mg/kg ALA verildi. Deney sonunda çıkarılan böbrek dokuları histolojik, immünohistokimyasal ve MDA düzeyi tayini metotları kullanılarak incelendi. TD grubuna ait böbrek kesitlerinde inflamatuar hücre artışı, Bowman boşluğunda artış, tübül lümeninde hiyalin birikimi gibi histopatolojik bulgulara rastlandı. ALA uygulaması ile histopatalojik bulguların büyük bir çoğunluğunda azalma gözlendi. TD grubunda VEGF immünreaktivitesinin kontrol grubuna göre anlamlı artış gösterdiği, TD+ALA grubunda ise TD grubuna göre anlamlı derecede azaldığı belirlendi. MDA seviyelerinde ise TD grubunda, kontrol grubuna göre anlamlı artış olduğu tespit edildi. Sonuç olarak, gebelik boyunca tütün dumanı maruziyetinin böbrek dokularında histopatolojik hasara ve damarlanmada artışa neden olduğu, ALA’nın ise bu etkilere karşı kısmen koruma sağladığı belirlendi.

King Oyster Mushroom, Pleurotus eryngii (Agaricomycetes), Extract Can Attenuate Doxorubicin-Induced Lung Damage by Inhibiting Oxidative Stress in Rats
(International Journal of Medicinal Mushrooms, 2023) Kaya Tektemur, Nalan; Tektemur, Ahmet; Güzel, Elif Erdem
Doxorubicin (DOX), a broad spectrum chemotherapeutic, has toxic effects on healthy tissues. Mitochondrial processes and oxidative stress act in the DOX-induced toxicity, therefore antioxidant therapies are widely used. The study was aimed to evaluate the therapeutic potential of Pleurotus eryngii extract (PEE), an extract of a fungus with antioxidant properties, against DOX-induced lung damage. Rats were divided into Control, DOX, DOX + PEE, and PEE groups (n = 6). DOX was administered intraperitoneally in a single dose (10 mg/kg BW) and PE (200 mg/kg BW) was administered by oral gavage every other day for 21 days. Histopathological evaluations, immunohistochemical analyses, total oxidant status (TOS)/total antioxidant status (TAS) method, and quantitative real-time polymerase chain reaction (qRT-PCR) analysis were performed. DOX led to severe histopathological disruptions in rat lungs. Also, DOX remarkably increased the expression of dynamin 1 like (DRP1) and decreased the expression of mitofusin 1 (MFN1) and mitofusin 2 (MFN2) genes, which are related to mitochondrial dynamics. Moreover, DOX caused an increase in TOS/ TAS and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels. On the other hand, PEE treatment remarkably normalized the histopathological findings, mitochondrial dynamics-related gene expressions, markers of oxidative stress, and DNA damage. The present study signs out that PEE can ameliorate the DOX-mediated lung toxicity and the antioxidant mechanism associated with mitochondrial dynamics can have a role in this potent therapeutic effect.
