[Expression of Fas protein in myocardiac tissue of viral myocarditis and dilated cardiomyopathy].

Objective: To study the pathogenesis of viral myocarditis (VMC) and dilated cardiomyopathy (DCM) and their relationship.

Methods: Sixty samples including 20 VMC, 20 DCM and 20 controls were collected. The expression of Fas protein in myocardium of each group was detected by modified immunohistochemistry with unequivocal brown staining in the myocardial membrane scored as positive, and the results of positive reaction were analyzed by Ridit test.

[Bcl-2 expression following the brain concussion in rats].

Objective: To evaluate the expression of Bcl-2 protein after brain concussion.

Methods: Expression levels of Bel-2 protein in cortex, pontine and cerebellum of rats were investigated using immunohistochemistry.

Results: There was no expression of Bcl-2 protein in control group seen.

[Apoptosis in myocardial cells after macleaya cordata total alkaloids poisoning in rats].

Objective: To observe pathological changes and apoptosis in rats myocardial cells after Macleaya cordata total alkaloids poisoning, and to provide some references for Macleaya cordata total alkaloids poisoning detection.

Methods: An experimental model of Macleaya cordata total alkaloids poisoning was established, and the technology of TUNEL staining was used.The results were analyzed by computer image analysis competitive system.
