Background: Bleeding time is a laboratory test to assess the platelet function. It is dependent on various factors like function of platelets and pathway of coagulation. Clotting time is the time required for a sample of blood to clot in vitro under standard conditions. It is known from previous studies that there is a difference in the bleeding time and clotting time among males and females. The exact reasons for such differences have been postulated, but are insufficient. Therefore the aim of this study is to study and compare the gender differences in bleeding time and clotting time in young male and female subjects. Aims and objectives: The aim of this study is to determine and compare the differences in bleeding time and clotting time in young adult male and female subjects. Materials and Methods: This study was done in the Department of Physiology, Raichur Institute of Medical Sciences, Raichur. Sixty medical students studying in first year M.B.B.S, were selected for the study, out of which thirty were males, and thirty were females. Bleeding time was determined by Duke’s method and Clotting time was determined by Wrights Capillary tube method. Data was analysed using SPSS software. Unpaired ‘t’ test was used for comparing the values. p value less than 0.05 was considered significant. Result: The mean value of bleeding time in males was found to be,127.69±51,02 and in females it was 133.28±44.30. The mean of the CT in males was 212.18±60 and in females it was found to be 257.16±61.00.The mean BT and CT was significantly higher in females as compared to the males. Conclusion: It was found that there are differences in bleeding time and time in males and females, BT and CT were statistically more in females as compared to females.

SUMMARY Young adult male rabbits were thyroidectomized or treated with methylthiouracil and adrenal weights determined after 3 or 6 weeks. No significant changes were seen following thyroidectomy. After 3 weeks of methylthiouracil treatment the mean absolute weight of the adrenal glands, but not the relative weight, was reduced. After 6 weeks both the absolute and relative weights were increased above the control levels, but the differences were not statistically significant. The results are compared with those obtained by other workers for rabbits and for other species.

Objectives. To evaluate the tooth size discrepancy and Bolton’s ratios between male and female subjects with a Class I malocclusion. Materials and Methods. The digital e-models of 100 male and 100 female 12-year-old southern Chinese children with a Class I malocclusion were selected. The mesiodistal widths from permanent first molar to the contralateral side first molar of the upper and lower dentitions were measured. Differences between the tooth size discrepancy, together with the anterior and overall Bolton’s ratios between male and female subjects, were assessed using a two-sample t-test. A paired t-test was used to determine differences between antimetric pairs of teeth within the same arch. Results. Females had statistically significant smaller teeth than males (P < 0.05) except the upper left and lower left lateral incisor and lower left and right central incisors. The mean values of anterior Bolton’s ratios for males and females were 77.04 and 77.03, respectively (P > 0.05), while the mean values of overall Bolton’s ratios of male and female are 90.48 and 90.65, respectively (P < 0.05). The clinical significant differences (Cohen’s d > 0.2) for contralateral tooth size were shown on the maxillary canines, lateral incisors, and central incisors of males; and mandibular canines and lateral incisors of females. Conclusions. Southern Chinese females presenting with Class I malocclusions have smaller mesiodistal tooth dimensions compared to males. Both males and females presented several tooth size asymmetries. There are no statistical differences in anterior and overall Bolton’s ratios between the genders.

This study is aimed to explore the Heart Rate Variability (HRV) response during short-term exercise by stair stepper and to compare the finding between young healthy male and female subjects. The responses were statistically analyzed by applying independent-samples t-test statistical method. The calculation of Coefficient of Variation (CoV (%)) and the slope of the linear regression is used to assess the steadiness of the HRV. Furthermore, the results also demonstrated that female subjects had greater significant p-value of RMSSD feature and significance p-value in a LF feature is greater in male. Thus, the ongoing results demonstrated that males have the sympathetic drive and females have predominant parasympathetic drive using short-term exercise by stepper. Thus, the experiment results indicate the suitability of developing rehabilitation devices in the field of Autonomic Nervous System (ANS), research, control system and rehabilitation enginering, which may help to isolate males and females.

Background It was reported that females are having high Bleeding time and clotting time than males. The reason for prolonged bleeding and clotting time in females is not clear. The studies on Bleeding time and Clotting time in healthy male and female college students of Kerala are inadequate. Therefore the present study was undertaken to measure and compare bleeding time and clotting time in male and female college students. Methodology Two hundred and twenty two healthy male and female college students, were enrolled in the present study. Bleeding time was estimated by Duke Method and clotting time was estimated by capillary tube method. Results Mean age of the participants of present study is 19±1. We have observed higher bleeding time (BT) and clotting time (CT) in females (155.45±34.91 seconds and 318.18±64.40 seconds) than males (96.06±55.05 seconds and 223.01±50.74 seconds) which is statistically significant (p value <0.001). Minimum and Maximum bleeding time observed in females is 2minutes and 4 minutes respectively while in males, it is 30 seconds and 3 minutes 30 seconds respectively. Minimum and maximum clotting time observed in females is 3minutes 30 seconds and 10 minutes respectively while in males, it is 2 minutes 30 seconds and 5 minutes respsectively. Conclusion Our study suggests that bleeding and clotting time are slightly higher in females. We recommend further detailed study in this area.
