The Effect of Hydro-Alcoholic Extract of Fenugreek Seeds on Female Reproductive Hormones in Mice
Essential Thrombocytosis Following Multiple Psychic Traumas
The associations between exposure to traumatic events and psychiatric disorders such as posttraumatic stress disorder (PTSD), depression, and anxiety have been established. It is important that clinicians notice to this phenomenon and avoid from inappropriate interpretations and additional laboratory tests. Here, a case of 45-year-old man with Essential thrombocytosis developed after multiple psychic traumas was introduced
Life expectancy at birth in Aran-Bidgol region, Iran, 2012: A study based on corrected Health Houses data
Background and aims: Life expectancy is one of the most important indicators of health and well-being of a society. Since it is claimed that in Aran-Bidgol region, center of Iran, life expectancy is higher than the average of the country, this study was designed. Methods: During a cross-sectional study, population and mortality data of Kashan University of Medical Sciences (KAUMS) in 2011 were used for calculating life expectancy. Brass Growth-Balance method was used to adjustmortality data with over 5 years old and to correct under reporting of deaths. Completeness and coverage of death registration data and the correction factor were calculated. Finally, anadjustedlife table for males and females was calculated separately. Microsoft Excel 2007 was used for calculations. Results: Population of Aran-Bidgol was 93571 in 2012 based on KAUMS data. Among the total population, 47331 (50.6) were males. Number of registered deaths was 479 280 male (58.4%). Completeness of the death registration data was found to be %74.9 for males and %70.1 for females. Correction factor (K) for adjustment of reported death was calculated to be 1.33 and 1.42 for males and females respectively. Adjusted life expectancy at birth for males and females was 71.3 and 76.5 years respectively. Conclusion:Although adjusted life expectancy for females in our study was to some extent more than the average life expectancy of Iranian women, but this indicator was slightly lower in men. Generally, it seems that there is no considerable difference between life expectancy of Aran-Bidgol population and national average life expectancy
The effect of MDMA and pentoxifylline drug on bad/bcl-xl gene dosage expression changes on rat liver
MDMA generally known as ecstasy, have deleterious effects on the serotonergic neurotransmitter system. Recent findings suggest that the liver and brain are major target organs of MDMA-related toxicities. Although most research is being dynamically performed on brain, however, the molecular mechanisms by which MDMA elicits adverse effects in both organs are poorly undrestood.The present study was performed to obtain evidence for molecular mechanism of apoptosis involved in MDMA-induced hepatotoxicity in rat liver after MDMAadministration. Moreover, the antagonistic effect of pentoxifylline was assessed on hepatotoxicity after MDMA administration. In this experimental study, sample size and power in each group were calculated as 10 rats with 95% confidence level and 5% confidence interval. In the study, four experimental groups were selected including Control Normal, MDMA, MDMA+PTX and PTX+MDMA. MDMA was dissolved in PBS and intraperitoneally injected three doses of 7.5mg/kg with two hours gap between doses. Pentoxyfilline also was injected as 100mg/kg, simultaneously with third dose of MDMA. After treatment, total RNA was isolated from liver tissue (5mg). Absorbance at 260nm, 280nm and 230nm were measured and immediately reverse transcription was performed. Included target genes were BAD and BCL-XL as pro-apoptotic and anti-apoptotic gene, respectively. After set up and validation, Real-Time PCR were performed and obtaining data were statistically analyzed to determine significantly differences between groups. Using Real-Time quantitative PCR results, BCL-XL gene expression ratio significantly increased in MDMA+PTX group. Moreover, BAD gene expression ratio increased and up-regulated in PTX+MDMA group (P-value <0.001).Our study focused on molecular mechanism of MDMA in programmed cell death using gene expression quantification of a pro-apoptotic and anti-apoptoic gene in MDMA-induced hepatotoxocity. The results shown MDMA prompted apoptosis in liver and pentoxifylline protects hepatotoxicity after and befor taking MDMA.
Diagnostic Value of Serial Ultrasound in Blunt Abdominal Trauma
Background Ultrasound has widely been used to assess patients with blunt abdominal trauma and detect free fluid in the abdomen. Nevertheless, different studies reported different false negative for this imaging technique. Objectives The present study was conducted to evaluate the diagnostic value of the repetitive ultrasound in diagnosis of free intraperitoneal fluid. Methods In this study, 125 patients with abdominal blunt trauma were recruited prospectively for ultrasound evaluation. Ultrasound and CT- scan were performed for all recruited patients in the study. In case of positive ultrasound or CT-scan (free fluid in the peritoneal cavity), patients underwent surgical operation. In the presence of negative ultrasound and CT-scan, and if the patient was alert and had stable vital signs, then, he/she would undergo exact supervision. In such patients, ultrasound and CT-scan were repeated 12 and 24 hours after admission. If any of the tests were positive, the patient underwent laparotomy. Moreover, if ultrasound and CT-scan examinations were negative 24 hours after admission, the patients with normal laboratory tests were discharged according to the surgeon's decision. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Results Of the 125 patients with abdominal blunt trauma, 90 patients finally underwent laparotomy. Based on the surgical outcome as the gold standard, the initial, 12 hours, and 24 hours sensitivity were measured to be 19.8, 75.2, and 82.2, respectively. These numbers for specificity were 91.7, 75, and 70.8, respectively; they were 90.9, 92.6, and 92.2 for PPV, and 21.3, 41.8, and 48.5 for NPV, respectively. Conclusions The sensitivity of ultrasound to detect intraperitoneal fluid in blunt abdominal trauma cases will be increased by repeated ultrasound examinations
Cerebral state index versus Glasgow coma scale as a predictor for in-hospital mortality in brain-injured patients
【Abstract】Objective: To compare the value of Glasgow coma scale (GCS) and cerebral state index (CSI) on predicting hospital discharge status of acute braininjured patients.
Methods:In 60 brain-injured patients who did not receive sedatives, GCS and CSI were measured daily during the first 10 days of hospitalization. The outcome of prognostic cut-off points was calculated by GCS and CSI using receiver operating characteristic
(ROC) curve regarding the time of admission and third day of hospitalization. Sensitivity, specificity and other predictive values for both indices were calculated.
Results: Of the 60 assessed patients, 14 patients had mild, 13 patients had moderate and 33 patients had severe injuries. During the course of the study, 17 patients (28.3%) deteriorated in their situation and
died. The mean GCS and CSI in patients who deceased during hospitalization was significantly lower than those
who were discharged from the hospital. GCS<4.5 and CSI<64.5 at the time of admission was associated with
higher mortality risk in traumatic brain injury patients and GCS was more sensitive than CSI to predict in-hospital death in these patients. For the first day of hospitalization,
the area under ROC curve was 0.947 for GCS and 0.732 for CSI.
Conclusion: GCS score at ICU admission is a good predictor of in-hospital mortality. GCS<4.5 and CSI<64.5 at the time of admission is associated with higher
mortality risk in traumatic brain injury patients and GCS is more sensitive than CSI in predicting death in these patients.
