劳动复合方案对小鼠血浆心钠素和耐力的实验研究

昆明种小鼠56只，在两个海拔高度上（300m和5000m）各分为两个组（对照组和复合组），分别给予相应的处理因素后，检测其血浆ANP水平和游泳时间。结果表明，小鼠在海拔5000m生活48h后，其血浆ANP较海拔300m小鼠降低52．87％，而其游泳时间则增长91．59％；在两个海拔高度上，复合组血浆ANP都较对照组降低，而游泳时间都长于对照组．提示复合方案提高高原劳动能力的机理，可能与降低体内血浆ANP水平有关。

STUDY ON PLASMA ANP LEVEL AND PHISICAL DURATION IN MICE TREATED BY COMPLEX TREATMENTS

Fiftysix Kunming mice were divided into control and complcx groups respectively at high altitudes of300m and 5000m. Each group was treated respectively as its name indicated. The concentration of ANP inplasma and swimming time were determined. It showed that plasma ANP level in mice lived at high altitude of5000m for fortyeight hours was significantly lower than at high altitude of 300m, but swimming time at5000Tn was longer than that at 300m. It showed that at the two altitudes,plasma ANP level of complex groupwas lower than control group. Swimming time of complex group was longer than that of control group. Thoseindicated that the mechanism of work capacity improved by the complex treatments was probably related withthe reduced plasma ANP level.
