One month later. Serum GH, THT3, THT4 and insulin were determined by using radio-immunity assay. The results demonstrated that both serum GH and insulin raised remarkably in experimental groups. THT4 raised only in peritioneal injection group. Besides these, the four different serum hormones showed no obvious change when the dose of samarium chloride decreased to 0.025 mg/kg with caudal vein injection.展开更多

The study found that salivary testosterone of sprinters significantly decreased after large and medium training loads, and returned to original level after l2 hours. Salivary tesosterone of long distance runners increased after small loading volume, but significant1y decreased after 1arge and medium loading vo1ume, and returned to original level after 6 hours.Change of salivary testosterone of men in a day showed certain regularity, being high in the morning and low in the afternoon. The change of salivary testosterone observed in this study was caused by exercise.展开更多
