Changes of pulmonary Water Content in Experimental Animals During Early phase of Hypoxia / 第三军医大学学报

ABSTRACT

This paper is to report our results of the observation on the changes of the pulmonary water content of the rats and mice after their exposure to a simulated altitude of 6000 meters above sea level for seven days.It was found that the changes of the pulmonary water content varied with the duration of exposing to the high altitude. It was lower than the control value on the first day of exposure, and then it increased approaching or even being a little higher than the control value on the second and third day. But it decreased and was below the control value again from the fourth day to the seventh day. The lung weight was increasing continuously in the same period.In addition, there were progressive increase of both the wet-lung/body and dry-lung/body indices, progressive decrease of left/right ventricles ratio, and gradual rising of hemoglobin in the animals studied.
