경주마(競走馬)의 혈액화학성상(血液化學性狀)에 관한 연구: I. 혈청효소(血淸酵素) 활성치(活性値)

Studies on the Blood Chemical Properties in Racehorses: I. Serum Enzyme Activities

The present study was carried out to investigate the serum enzyme activities of racehorses. The enzymes investigated were aspartate and alanine aminotransferase (GOT, GPT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Lactic dehydrogenase(LDH), creatine phosphokinase(CPK), and alkaline phosphatase(ALP). Animals used were 30 healthy racehorses(♀17, ♂13) average weighing 435kg and were from 2 to 8 years of age. LDH activity was progressively decreased with age and next in the order of GOT and CPK activities. GOT and ${\gamma}$-GPT activities were not changed with age but ALP activity tended to be decreased wish age. Activities of GOT, GPT, ${\gamma}$-GTP and ALP were higher in female than in male. There was no difference in CPK activity by sex, and no difference was found out among breeds.
