We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.展开更多

The objective of this research is to critically analyze the age and gender based variations of thyroid volume and thyroid hormone levels in the hospital based euthyroid subjects. Methodology: A total of 221 euthyroid subjects aged 1 - 86 years were selected to observe the normal thyroid size by ultrasonography at Department of Radiology and the thyroid function test values (FT3, FT4 and TSH) of 2413 euthyroid subjects aged (Results: The best fitted equations with significant correlation coefficients and p Conclusion: The thyroid size first increases and then decreases whereas the thyroxin level first decreases and then increases with aging. Left lobe volume is almost same for both genders and right lobe volume is higher in males. The thyroid size in menarche and menopause periods of females is larger than that of males. Such age- and gender-specific changes recommend the new refer-ence ranges for the normal thyroid functions.展开更多

(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
