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.
Effect of Auricular Acupressure in Management of Constipation in Palliative Care Patients
(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.
Effect of Foot Massages on Postpartum Comfort and Pain Level of Mothers after Vaginal Delivery: A Randomized Trial
(Holistic Nursing Practice, 2021) İçke, Sibel; Genç, Rabia
This study conducted on 66 mothers aimed to investigate the effect of foot massages postpartum using an introductory information form, the Postpartum Comfort Scale, the visual analog scale, and a drug follow-up card. It was concluded that foot massages positively improved comfort, reduced pain levels, and reduced unnecessary medications.
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.
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.
