Objective:To evaluate and compare the antimicrobial efficacy of 6% Morinda citrifolia, Azadirachta indica, and 3% sodium hypochlorite (NaOCl) as root canal irrigants.Materials and Methods:Thirty nonvital maxillary anteriors were randomly assigned to one of the three groups corresponding to the irrigant to be tested; 6% Morinda citrifolia juice (MCJ) (n = 10), A. indica (n = 10) and 3% NaOCl (n = 10). After the root canal access opening a root canal culture sample was taken with two paper points and cultured under aerobic and anaerobic conditions. Cleaning and shaping were completed with irrigation by 10 mL of respective irrigants and 5 mL of final rinse. The patients were recalled after 3 days and canals were rinsed again with 5 mL of the test irrigants. This was followed by obtaining a posttreatment root canal culture sample and culturing and analyzed by counting the colony forming units (CFUs).Results:Six percentage MCJ, A. indica, and 3% NaOCl showed a significant reduction (P < 0.05) in the mean CFU counts for aerobic and anaerobic bacteria between baseline and 3 days.Conclusion:There was no difference in the antimicrobial efficacy of 6% M. citrifolia, A. indica, and 3% NaOCl as root canal irrigants.

An inspiratory decline in systolic arterial blood pressure exceeding 10 mm Hg has been used clinically to identify hemodynamically significant pericardial effusions. Recently, the echocardiographic sign of right ventricular diastolic collapse (RVDC) has been shown to occur early in the course of cardiac tamponade in association with a hemodynamically important decline in cardiac output. This study was undertaken to compare the relative merits of pulsus paradoxus and the onset of RVDC in the early detection of cardiac tamponade in an unanesthetized canine preparation. We studied six chronically instrumented, conscious dogs with two-dimensional echocardiography during cardiac tamponade induced by continuous infusion of saline into the pericardial space. We recorded intrapericardial pressure, cardiac output (electromagnetic flowmeter), aortic (catheter-tip transducer) and right atrial blood pressures, heart rate, and respiration. None of the dogs had RVDC when the pericardial space was empty, but all dogs showed RVDC during cardiac tamponade. We found that RVDC was strongly related to all of the cardiac parameters evaluated (intrapericardial pressure, cardiac output, aortic blood pressure, heart rate, and stroke volume) and provided information on each that was independent of that provided by pulsus paradoxus. Furthermore, RVDC appeared to be more strongly related to most cardiac parameters than was pulsus paradoxus and to be more sensitive and specific than pulsus paradoxus in detecting changes in intrapericardial pressure early in cardiac tamponade. Circulation 71, No. 4, 829-833, 1985. ECHOCARDIOGRAPHY is a sensitive and accurate method for the detection of pericardial effusion. ' The use of echocardiography to assess the hemodynamic effects of progressive pericardial effusion has been described recently.

Background: Premenstrual syndrome (PMS) is a disorder affecting large number of population in terms of their physical and psychological well-being. A large number of college drop outs are because of PMS. Aims and Objectives: The objective of this study was to assess the prevalence of presence of different symptoms of PMS and premenstrual dysphoric disorder (PMDD) among medical college girls and its effect on their social and academic life. Materials and Methods: This study was conducted in a medical college in 1

Background: Obesity is the leading public health crisis of our time. A chronic imbalance between energy intake and energy expenditure will eventually lead to obesity. Several micronutrients are found to be involved in the development of obesity. Magnesium is found to have some role in the development of obesity. Aims and Objective: Objective of this study was to evaluate the correlation of serum magnesium with different parameters of obesity such as body weight, basal metabolic rate, waist circumference (WC), and waist-hip ratio on the basis of the hypothesis that subjects with hypomagnesemia are more prone to develop obesity. Materials and Methods: This is a population-based cross-sectional study. A total of 130 apparently healthy adults of age between 25 and 65 years, were recruited with prior ethical approval and written informed consent. Results: Serum magnesium was found to have significant negative correlation with body weight (r = −0.30, P = 0.003) and WC (r = −0.21, P = 0.03). Correlation with rest of the parameters was not significant. Conclusion: On the basis of results it is concluded that hypomagnesemia can be proved to be one of the important predictors of obesity.
