Background: Blood group and its relation to bleeding time (BT) and clotting time (CT) is important in conditions like epistaxis, thrombosis, and surgery. Earlier studies depicted O group having prolonged BT and CT. The aim of this study was to assess the relationship of BT and CT with ABO groups.Methods: This cross-sectional study was conducted in the department of physiology, Gauhati medical college. The study included 154 students. Blood grouping was determined with the standard antiserum; BT and CT were estimated by the duke method and slide method, respectively. Blood group and its relation to BT, CT were analyzed by Chi-square analysis.Results: Blood group O (42.2%) was predominant in both genders followed by B (31.8%), A (21%), AB (4.5%). CT was found to be more than 6 minutes in group O (31.57%) followed by group AB (26.31%), A and B (21.05%). The difference was statistically significant (p = 0.02). BT was found to be more than 4 minutes in group O (82.35%) followed by A (11.76%), B (5.88%), and AB (0%). That was statistically significant (p = 0.01). CT was more than 6 minutes in 57.89% in females as compared to 42.10% in males, variation was statistically significant (p = 0.01). BT was more than 4 minutes in 58.82% females as compared to 41.17% in males. The variation was statistically significant (p = 0.03).Conclusions: In present study blood group O was more common followed by B, A, and AB. CT and BT were prolonged in O group. BT and CT were more in females than males.

Background: Measurement of glycosylated hemoglobin (HbA1c) is considered the gold standard for monitoring chronic glycemic level of diabetes patients. HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. Levels of HbA1C represent the average blood glucose levels of diabetic patients over the previous 120 days. The objective of this study was to see the correlation between HbA1c levels and glucose levels. Methods: This cross-sectional study included 60 randomly selected subjects with known diabetes. Both fasting and post prandial blood glucose levels were measured by using venous blood samples. HbA1c levels were measured in venous blood by immunoturbidimetric method. Data were recorded on a proforma in MS-excel sheet. Pearson's coefficient of correlation was applied to find out any significant correlation between the HbA1c levels and the both fasting and postprandial blood glucose levels. Results: Results were obtained by statistical calculation and plotted with respect to scatter and bar diagram was done and a p<0.05 was considered significant (With 95% CI). Conclusions: A significant linear positive correlation exists between levels of HbA1C and fasting and post prandial blood glucose.

Background: Muscle strength has been studied as a predictor of general health and many diseases.  Data on muscle strength of healthy adults are scarce in Assam. Aim of the study was to describe normative data for hand grip muscle strength and endurance among healthy young males and females of age group 18-21. Also, to find out any correlation between muscles strength and endurance.Methods: We have selected 79 healthy volunteers of both sexes of age group 18-21 years. We have measured muscle strength by hand grip dynamometer. Muscle endurance was calculated by asking the subjects to hold the dynamometer at one third of their muscle strength as long as they can.Results: In this study there were 46 males and 33 females. Mean muscle strength among the males is 27.09(SD7.05) and among the females is 10.76(SD6.19). Similarly mean endurance among males is 41.78(SD31.72) and among females is 16.15(SD9.81). These higher values of muscle strength and endurance in males are statistically significant. We have also found positive correlation between muscle strength and endurance in both the sexes.Conclusions: In this study we have seen that muscle strength and endurance of healthy young males are more than that of females. And also, muscle endurance increases with increase in muscle strength.

Background: There is alarming rise in number of people with diabetes mellitus over these years. Type 2 diabetes mellitus is the fifth most common condition and the sixth leading cause of mortality amongst the elderly. Finding a relationship between the blood glucose level and its concentration in other body fluids such as the saliva can help in developing an on invasive method for blood sugar assessment replacing venous sampling. Objective of this study was to see the correlation between fasting blood glucose and fasting salivary glucose levels. Methods: This cross sectional study included 200 randomly selected subjects, of which 100 were known diabetes constituted test group and 100 were normal healthy subjects, age- and sex-matched individuals constituted the controls. Fasting blood glucose and salivary glucose levels were measured by using glucose oxidase peroxidase methods. Data were recorded on a preforma in Microsoft excel sheet. Pearson's coefficient of correlation was applied to find out any significant correlation between the fasting blood glucose and fasting salivary glucose levels. Results: Results were obtained by statistical calculation and plotted with respect to scatter and bar diagram was done and a p<0.05 was considered significant (with 95% CI). Conclusions: A significant positive correlation exists between fasting blood glucose and fasting salivary glucose in both the test groups.
