Abstract:
ObjectiveTo investigate the effects of Yinhuang solution on the bladder mucosal before and/or after mucosal injury.Methods32 SPF female SD rats were randomly divided into 4 groups with 8 rats in each group. Group A was used for the normal control group, group B for the model control group, group C for preventive group, group D for preventive and therapeutic group. Injured rats were created by hydrochloric acid applied on bladder mucosa. After the models were established or before and after the models were established, bladders were perused with Yinhuang solution. Severity of inflammatory infiltration were observed by HE staining, histological score and heat shock protein 70 (HSP70) expressed in the mucosa.ResultsEndoscopic pathological change showed that group B had a large number of inflammatory cell infiltration, significant expansion of capillary, epithelial cell necrosis. Group C had a small amount of expansion of capillary, inflammatory cell infiltration. Group D scattered in expansion of capillary, a small amount of inflammatory cell infiltration. Concerning the results of histological score and HSP70 expression, there was a significant difference between group A and groups B, C or D (P<0.01); there was a significant difference between group B and groups C or D (P<0.01); there was a significant difference between group C and group D (P<0.05).ConclusionYinhuang solution can evidently improve the repair capability of bladder mucosa after injury.
