Objective: To investigate the effect of
Qianlie Huichun capsule on the microstructure and
ultranstructure of prostate glandular
tissue in the model rat. Method: Hynertophy of prostate model rat was established by injecting testosterone to gelding male rats. After having been fed with
Qianlie Huichun capsule for 30 days, the rats were killed and prostate tissues were resected for pathomorphological studies with microscope and electromicroscope, and the diameter of glandular lumer and the height of glandular epithelial cells were measured under the microspcope for different groups of rats. Result: In the model groups, the glandular epithelial cells mutiplycated notably,showing stratified and pseudostratified cells that made the glandular lumer cramped. Under the electromicroscope, the glandular epithelial cells became high columnor and the rough endoreticulum extremely expanded.But in treatment groups, the change of the diameter of the glandnlar lumer and the hight of the glandular epithelial cells were less remarkable than those in model groups. So the differerence between the model group and the treatment groups was remarkable (P<0.01). Conclusion: Qianlie Huichun capsule can depress the glandular epithelialceu multiplication of prostate gland in model rats.
