STUDY OF iNOSmRNA IN PULMONARY TISSUES OF TAIL-SUSPENDED RATS DURING SIMULATED WEIGHTLESSNESS / 解放军医学杂志

ABSTRACT

To investigate the changes of inducible nitric oxide synthase mRNA (iNOSmRNA) in pulmonary tissues of tail suspended rats during simulated weightlessness, experiments on 40 Spragno Dawley male rats were conducted. The rats were divided into 4 groupssuspended for 7d, and its control, suspended for 21d, and its control tail suspension(-30 ) was used as weightlessness simulation.The condition of iNOSmRNA in pulmonary tissues was examined by hybridization in situ.The results showed that the level of iNOSmRNA in pulmonary tissues of 7d tail suspended rats increased significantly( P
