ABSTRACT
Background — Over the past years, there seems to have been good attention paid to the connection between some diseases and the ABO blood group type. To our knowledge, nostudy has been done todetermine the association between obesity and ABO blood group. To find the prevalence of obesity in medical students and to determine theAims — association between obesity and ABO blood group. A cross sectional study was carried outMaterials and methods — among 745 medical students. Height, weight, waist circumference, hip circumference was measured. BMI and waist —hip ratio was determined. Blood group was determined by slide agglutination method The findings of theResults — present study reported that the most prevalent blood group was B+ whereas the blood group AB was least prevalent. 25.5% of the total study subjects were overweight and 7.2%were obese. Overweight and obesity were more common among students with blood group B. It was also observed that WHR statistically associated with ABO Blood group system. Conclusion — Participants with blood group B+ had higher prevalence of overweight and obesity. ABO Blood group system showed statistically significant association with WHR.
ABSTRACT
In COPD, overactivation of ergoreceptors may be a link between peripheral changes, sympathetic over activation and increased hemodynamic and ventilatory responses to exercise. The current study was undertaken to test the hypothesis that, ergoreflex in COPD patients is hyperactive and contributes to breathlessness and exercise limitation. The aim of study was to (1) demonstrate its hyperactivity in COPD (2). To record other efferent effects. Twenty stable COPD male patients aged 50±2.5 years and twenty healthy male subjects aged 48±3.5 years were studied under experimental and control groups. The ergoreflex contribution to cardio respiratory parameters was assessed by post-handgrip regional circulatory occlusion method (PH-RCO) and computed as the difference in heart rate and respiratory rate response between PH-RCO and control run without PHRCO. Results were analyzed for significance between two groups by repeated measures ANOVA. COPD patients showed over activation of ergoreflex as compared to control subjects in terms of heart rate during sustained hand grip (SHG) exercise (117±1.22 versus 89±0.89) beats/min, recovery heart rate (p<0.001), and respiratory rate during SHG (24±0.54 versus 19±03.24) breaths/min and recovery respiratory rate (p<0.001). Degree of overactivation of ergoreflex was significant in COPD patients (p<0.001). In COPD, overactivity of ergoreflex is associated with abnormal cardio respiratory reflex control. COPD patients showed overactivation of sympathetic nervous system as evidenced by heart rate changes during exercise and delayed recovery.
