双峰驼血清中抗利尿素和醛固酮含量的动态研究

本研究首次对双峰驼在不同饮水条件下血清中抗利尿素（ＡＤＨ）和醛固酮的含量进行测定,结果表明：双峰驼正常血清中ＡＤＨ和Ａｌｄｏ科夏季含量均值为０．５５和５９．８５ｐｇ／ｍｌ。Ａｌｄｏ比ＡＤＨ高１００多倍。ＡＤ盼望同于冬季,禁水后两 明显增加,禁水１５天时ＡＤＨ和Ａｌｄｏ增加为０．７６４和１３０．４８ｐｇ／ｍｌ,禁水期ＡＤＨ含量的季节差异逐渐缩小;而Ａｌｄｏ的季节差异则显著扩大,１５天时Ａｌｄｏ夏季含

THE DYNAMIC STUDY OF ANTIDIURETIC HORMONE(ADH) AND ALDOSTERONE(ALDO) CONTENTS IN BLOOD SERUM UNDER THE DIFFERENT CONDITIONS OF WATER DRINKING ON BACTRIAN CAMELS

Antidiuretic hormone(ADH) and aldosterone(Aldo) contents in blood serum of bactrian camels were dynamically studied under the different conditions of water drinking for the first time.It was shown that the average contents of ADH and Aldo in blood serum of bactrian camels between winter and summer were 0 557 and 59 84 pg/ml,respectively Aldo was 100 times as high as ADH which was higher in summer than in winter( P <0 01).After dehydration,these hormones were significantly increased.ADH and Aldo reached up to 0 764 and 130 48 pg/ml at 15 days dehydration During the dehydration,the seasonal differences of ADH was gradually reduced,but those of Aldo rose sharply.Aldo content in the summer was 74 32% higher than that in the winter at the 15th day of dehydration ADH and Aldo levels were decreased to 0 499 and 32 86 pg/ml at the twelfth hours after the rehydration and gradually returned to the normal.These results indicated that these two hormones were negatively interrelated with the water as well as micturition volumes in the body and positively with the duration of dehydration.It was also shown that Aldo and ADH played more impotant roles in adjusting the water metabolism and micturition volumes of bactrian camels.
