| Abstract: |
| (Abstract〕 Objective To investigate the effects of Wenyang Qiagxin decoction (WQD)
on chronic congestive heart failure apoptosis and cardiac structure in rabbits. Methods Ten rabbits
were randomly selected as healthy control group(HCG) and tother 40 were induced by adriamycin to
prepare heart failure models. Then, according to the levels of heart functions evaluated by echocar-
Biography, the 40 model rabbits were assigned into 4 sub-groups: modeling group
(MG), captopril group(CG), WQD low dose group(LDG) and high dose group(HDG). All the animals
in each treating group were given corresponding medicine respectively, and those in HCG and the
MG were given the same value of distilled water administrated by gavage, once a day and lasted
for 4 weeks. By the end of experimental period, all these animals were put into death
to measure cardiac structure and function and to take tissue samples for determine apoptotic activi-
ty in cardiac muscle by surface density ratio of positive apoptotic cells for comparative analysis a-
mong different groups. Results Compared with that of MG, WQD significantly elevated the indica-
tors LVEF, LVFS and E/A were (P<0.01), and reduced obviously IVS and LVPW (P<0.01), and in LDG and HDG decreased markedly the surface density ratio of positive apoptotic cells (P<
0.05), in which the effects were much more superior in HDG to that in LDG. Conclusion
WQD can effectively improve the cardiac function of CCHF induced by adriamycin and signifi-
candy inhibit apoptotic activity in cardiac muscle and remodeling of cardiac ventricle among in
rabbits and the effects in HDG isbetter than that in LDG. |
