| Hui-Qing Liu, Wen-Bin Li, Rong-Fang Feng, Qing-Jun Li, Xiao-Ling Chen, Ai-Min Zhou, Hong-Gang Zhao, Jie A. [Effect of nitric oxide synthase inhibitor L-NAME on the induction of brain ischemic tolerance in rats]. Sheng li xue bao : [Acta physiologica Sinica]. vol 55. issue 2. 2012-08-16. PMID:12715115. |
the results showed that (1)10-min ischemic insult resulted in an increase in the histological grade (indicating a more serious tissue injury) and a decrease in pyramidal neuronal density (p<0.01); (2) the histological grade and neuronal density in hippocampal ca1 in the cip+ischemia group were similar to those in the sham-operated group (p>0.05); (3) in the l-name group, administration of l-name brought about an increase in the histological grade and a decrease in neuronal density (p<0.01), suggesting that l-name blocked the protection of cip; (4) the neuronal damage in l-name+l-arg group was slighter than that in the l-name group, but still more serious than that in the cip+ischemia group, suggesting that l-arg partly reversed the blocking effect of l-name; (5) the morphological representations in l-name+ischemia group were basically similar to those in the ischemia group. |
