本市对大武地区(海拔3800m)土生狗;平原地区(南京,海拔20m)实验动物兔、狗;平原动物进入西宁地区(海拔2260m)的翌日,动物进入大武地区的翌日和第7天;天峻地区(海拔3800m)藏系羊移居苏州地区(海拔10m)一月和移居平原1 1/2月后重返西宁第10天的肾ATPase活性变化,采用透射电镜进行差异比较观察。结果提示:①平原和高原动物肾ATPase活性处于相似水平;②平原动物进入高原后肾ATPase活性处于被抑制状态,随海拔增高,渐趋严重;③平原动物进入大武第7天,肾ATPase活性得到部分恢复;④高原羊移居平原1月,肾ATPase活性与平原动物的水平相似;移居平原羊1 1/2月后重返西宁第10天,肾ATPase活性降低。本文对肾ATPase活性的降低和恢复的生物学意义进行了探讨。
The following day, the animals entered the Dayu area and the 7th day of Dawu area on the following day after the animals entered the Xining area (2260m above sea level) in the plains area (Nanjing, 20m above sea level) Jun area (elevation 3800m) Tibetan sheep migrate to Suzhou (10m above sea level) in January and moved to plain after January 1/2 and returned to Xining on the 10th day of renal ATPase activity changes, the transmission electron microscopy differences were observed. The results showed that: ① The activities of ATPase in plains and plateau were at similar level; ② The activities of ATPase in placental animals entering the plateau were inhibited and increased with the altitude; ③After the placenta animals entered Dayu, the activity of ATPase Partially recovered; ④ In January, the plateau sheep migrated to the plain, the renal ATPase activity was similar to that of the plain animals; and the migrated plain sheep returned to Xining after the first 12 days and the renal ATPase activity decreased. This article on the reduction of renal ATPase activity and the biological significance of recovery were discussed.
