(Black seed), is a traditional herbal medicine that has been used for many purposes. The present study was designed to investigate the effects of hydro-alcoholic extract of nigella sativa L. (NS) on performance of Forced Swimming Test (FST), blood biochemical parameters related to fatigue and thyroid functions. Therefore, Blood Urea Nitrogen (BUN), Creatine Kinase (CK), Lactic Dehydrogenase (LDH), and Total Protein (TP), triiodothyronine T3, thyroxin T4 and TSH tests were investigated. Thirty five male adult mice were randomly divided into five groups: three NS-fed groups, one fluoxetine treated group and one control group. Three NS experimental groups received hydro-alcoholic extract of NS at doses of 50, 100 and 200 mg/kg orally for two weeks. Immobility time decreased in all NS groups compared with control group. Administration of NS significantly increased the concentration of T3 and T4 of the treatment groups. On the contrary, the amount of BUN, CK, LDH, TP and TSH decreased. In conclusion, black seed extract at the experimented doses showed anti-depressant, anti-fatigue and hyperthyroid effects.展开更多

Aim: The aim is to correlate thyroid functions with hepatic status in compensated and decompensated cirrhosis, and to study their effect on development of HCC. Settings and Design: Prospective controlled cohort study. A total of 58 patients with liver cirrhosis were recruited from Kasr AlAiny ER and outpatient clinics. Patients were categorised into compensated (11), decompensated (39) and patients with hepatocellular carcinoma (8). The study also included 12 healthy controls. Methods and Material: Liver function tests, TSH, FT4 and FT3 and abdominal ultrasound and triphasic computed tomography abdominal scans were done. Statistical Analysis Used: Chi-square and unpaired t-tests were used for comparison. One way ANOVA and Kruskal Wallis tests were used to compare more than two groups. Spearman Correlation followed by logistic regression analysis of significant variables was used to find predictors of dependent variables. Results: The frequency of patients with low FT3 was significantly higher in patients with liver cirrhosis (48%), and HCC (50%) than control subjects (12%) (p-value < 0.001). Mean serum FT3 was lowest among decompensated patients (2 pg/ml ± 0.7), followed by patients with HCC (2.5 pg/ml ± 0.7) and highest among compensated patients (3.7 pg/ml ± 0.4), p-value < 0.001. Logistic regression analysis showed that low FT3, male gender, ulcer bleeding and encephalopathy were independently associated with the development of HCC (OR, 95% CI: 1.1, 0.3 - 8). Conclusions: Low FT3 is common among patients with decompensated liver cirrhosis and HCC. FT3 shows a significant negative correlation with severity of liver disease and deterioration of liver function. Low FT3 shows a significant independent association with HCC.展开更多
