RESULTS: As compared with group I-R, Fas/FasL mRNA slightly expressed in intima and extima of small pulmonary artery, alveoli, and bronchiole epithelia in group Pur. The values of AI, W/D and IQA showed significantly lower than that in group I-R at 60, 180, 300 minutes after reperfusion in lung tissue (P.01 and P.05). Meanwhile, abnormal changes of the lung tissue in morphologically were lessen markedly in group Pur.

Results: Both Pur and Hup-A improved learning memory ability of I/R mice, the effect of Pur group was better and the effect of combination group was the most significant. Both Pur and Hup-A decreased neuron apoptosis and raised content of monoamine nervous transmitter of I/R mice. The cortex neuron apoptosis rate in combination group was lower than that in Hup-A group,the homovanillic acid level of cerebral cortex in combination group was higher than that of Pur group.
