ABSTRACT
Height is one of the important parameter for identification of the individual. The study was undertaken toestimate height of individual from arm span by regression equation and to compare it with measured height. Thestudy was carried out on 50 adult males and 50 adult females from Jalgaon, Maharashtra over a period of threemonths from February to April 2018. The population was randomly selected for this study. In present study,correlation coefficient between height and arm span in males is 0.73 while in females it is 0.69.The Regressionequation derived from arm span in male is Height = 47.26 + (0.72 X arm span) and in females Height =57.32 +(0.64X arm span). The derived equations were tested and difference between measured and estimated height wasfound non-significant.
ABSTRACT
Introduction: Coronary artery disease is responsible for 70% cases of sudden cardiac deaths. Small coronaryostia may cause significant difficulty in canulation of it during diagnostic and therapeutic procedures. Highorigin of coronary arteries increases risk of myocardial ischaemia and sudden death. Considering thesesignificance of variations of coronary ostia in cardiac procedures, detailed study was undertaken so it would beof use to cardiologists and interventional radiologists.Material and Methods: Sample size for the study comprised of 50 human cadaveric heart specimens. Dissectionmethod was adopted.Observation and Results: In anterior aortic sinus, 41 specimens had single ostium, while 09 specimens showedtwo separate ostia. The mean of ostium diameter of right coronary artery was found to be 2.84 mm with astandard deviation (S.D.) of +0.85 mm. The mean distance of main ostium of right coronary artery fromsupravalvular ridge was found to be 1.23 mm. with a S.D. of +0.32 mm. In case of accessory ostia in anterioraortic sinus, the mean diameter was found to be 1.32 mms. with a S.D. of +0.20 mms. The mean distance of theseostia from supravalvular ridge was found to be 1.16 mms. with a S.D. of +0.17 mms. In left posterior aortic sinus,49 specimens had single ostium, while 01 specimen had two separate ostia. This ostium was 0.8 mms. indiameter at a distance of 02 mms. below from supravalvular ridge. The mean of ostium diameter of left coronaryartery was found to be 3.31 mm with a S.D.of+0.52 mm. The mean distance of main ostium of left coronary arteryfrom supravalvular ridge was found to be 1.40 mm. with a S.D. of +0.27 mm.Conclusion: the study provides data on coronary morphometry and topography. It provides basis for understandingthe normal variants for determining incidence of anomalies and for evaluating value of screening of suchanomalies.
