A study of the prolactin cells of the rat pituitary gland has been presented. Serial sections of sixty pituitary glands from the pregnant and post partum rats of various period have been reacted with specific rabbit anti-prolactin and horseradish peroxidase labeled sheep anti-rabbit gamma globulin. Prolactin cells from 240 representative visual fields per group were counted under the higher magnification of light microscope and the following results were obtained. 1. There was sharp rising of number of prolactin cells in post partum lactating rats, while non-lactating group of post partum rats showed gradual decrease of cell number which revert almost to that of the pregnancy level. 2. Prolactin cells were more numerous in 2-day lactating rats than any other group of rats. It have increased by almost twice the number presented in control and pregnant rats. 3. No significant changes of cell number were observed in the pregnant group compared with the control group. 4. Although there were significant changes in prolactin cell number between post partum lactating and non-lactating rats, Iuteinizing hormone cells revealed little change. 5. Increment of prolactin cells seem to be occured evenly throughout the anterior lobe of pituitary gland.

The purpose of this study was to investigate the effects of elastic exercise training on functional fitness and physical activity levels of older women in different age ranges, and provide an appropriate elastic exercise program for each age group. The elastic band exercise program was composed of rating of perceived exertion(RPE) 11-13 for 35-50 minutes, 2 times a week for 12 weeks. Forty older women were devide by classified age range into 4 groups; 65-69, 70-74, 75-79 and 80-84 years old. The measure of functional fitness and physical activity levels. A within-group comparison revealed that all age group improved lower and upper extremity muscle strength, lower and upper extremity flexibility, and cardiorespiratory endurance following elasticband exercise training except BMI, agility and dynamic balance. Based on between-grpup comparison, 65-69, 70-74, 75-79 years old groups had a greater improvement than 80-84 years old group showed a greater improvements than 70-74, 75-79 and 80-84 years old groups. In all age groups, total energy expenditure and locomotion energy expenditure showed positive improvements in response to elastic band exercise. The total number of steps were increase in only 65-69 years old group. However, average walking speed did non change in all groups. Also, there were no differncese in the rates of change on any variables among the age groups.

Many studies have been reported on the effect of exercise for the obese women, but few reported that effects of exercise in old-aged women with obesity. So, the purpose of this study was to analyze the effect of aerobic exercise on body composition in old-aged obese women. The subjects were chosen by 98 cases with obese women(BMI 25 ㎏/㎡ over) who 60 to 70 years old. They exercised regularly 45min per day, 3times per week during 12weeks and the intensity of exercise was 40-60%HRR using treadmill. The older women's % body fat, LBM, WHR and VFA were examined before and after the exercise program. The results of the study were as follows ; After exercise program, there were significant differences in VFA and WHR between before and after exercise. Anywhere, % body fat and LBM were also reduced but there was no significant effect of training. From the above finding, it could be concluded that low and moderate intensity exercise program composed of walking and full body stretching could improve the body composition of older women with obesity. these findings provide evidence that exercise with walking and stretching is an effective intervention to change the body composition, especially, to reduce visceral fat area, waist-hip ratio for older persons without dietary therapy.
