Effects of Various Two Month Exercises on Urinary Creatinine Excretion, Muscular Strength and Body Composition.

The purpose of this study is to clarify what sports activity done for a period of two months improves muscular mass and strength and body composition. Twenty five healthy college male students volunteered to be subjectS. The subjects were divided into seven groups: a handball group (n=4), a basketball group (n=4), a valleyball group (n=4), a judo group (n=3), a badminton group (n=3), a basic training group (n=3) and a non-exercise group (n=4). Each group except the non-exercise group was a part of the college club for the named activity. They did not alter their normal club activity in any way. The variables determined in this study are as follows: urinary creatinine excretion, urinary specific gravity, grip strength, back strength, percent body fat (%Fat) and lean body mass (LBM). All of the urine samples were collected over twenty four hour periods, one at the start and one at the end of the study. The Folin-Wu method and skinfold thickness were used to determine urinary creatinine and body composition, respectively. This study found that there were no significant differences among changes of all variables between the Pre- and Post-tests by performing various exercise for two month periods. This study was supported in part by a research grant from the Ministry of Education in Japan

Isolation and Identification of Stereochemistry of Diastereomeric Hydrobenzoins, as a Teaching Experiment for Undergraduate Organic Chemistry

meso- and dl-Hydrobenzoin were easily isolated from a mixture of diastereomeric diols which was obtained from benzil or benzoin by reduction with sodium borohydride. Each structure was assigned by considering steric course of the reduction， chromatographic behavior and also spectral data
