目的：观察大鼠垂体切除后不同时段对下丘脑视上核ADH神经元的影响及尿崩情况。方法:利用垂体切除仪行立体定向大鼠垂体切除，术后监测每天的饮水量、尿量及尿比重，通过免疫荧光方法观察和测定术后不同时段视上核ADH神经元的存活情况。结果:术后平均每天饮水量、尿量实验组为73.9 mL和59.7 mL,均明显高于对照组的30.9 mL和14.7 mL，P<0.01；而尿比重实验组1.015低于对照组1.03...

Three male subjects were passively tilted from a supine to a 90 degree head-up standing position on 2 d each at 1 and 31 ATA, then on 1 d of the postdive period. On each day the subjects were tilted o...
Urinary ANP,ADH,and electrolyte excretion during saturation-excursion diving to pressures equivalent to 250 and 300 m
hyperbaric Urine saturation

Four male divers were exposed to an environment of 26 and 31 atm abs He-O2 for 2 days. Urine was collected during the day (0700-1900 h) and at night (1900-0700 h) before (predive 1 atm abs air), durin...
限氧与通氧条件下米根霉ADH突变株的碳代谢特性
米根霉 ADH 乙醇 L-乳酸
2008/9/2
【目的】乙醇脱氢酶（ADH）是米根霉发酵生产L-乳酸代谢途径中的支路关键酶，选育米根霉ADH突变株，降低ADH活力，可以提高乳酸转化率。【方法】利用亚硝基胍（NTG）诱变米根霉As3.3462，在含丙烯醇的YPD选择培养基上筛选获得ADH突变株，研究了突变菌株在限氧与通氧条件下的乙醇、乳酸、ADH与L-乳酸脱氢酶（LDH）的特性。【结果】 获得11株ADH突变株，其中mut-2突变株在通氧和限氧条...
X射线和ENU诱变的Adh基因对黑腹果蝇醇耐受性的杂合效应
果蝇 诱变剂诱变的Adh无效基因 醇耐受性 杂合效应
2008/2/8
摘要为研究部分显性的机制,用12个黑腹果蝇醇脱氢酶(DADH)基因内无效突变(Adhn)体作为材料。这些已知序列的突变体[包括单碱基置换或基因内小段缺失(9-16个碱基)],用来分析肽的合成,二聚体的形成和杂二聚体酶活性。杂合体中酶的部分表达和很广范围显性表达(从几乎完全隐性到高度显性)具多重机制。在10%乙醇的高度胁迫下,所有12个Adh^n|型果蝇中都观察到醇耐受性的部分显性表达。无效突变表达...
