Nitroglycerine was used in 21 cases of the control group. The results showed that the total effective rates in improving symptoms and electrocardiogram after garlicin treatment were respectively 82% and 62%, and that the plasma endothelin and blood sugar levels were markedly lowered in cases with hyperglycemia.展开更多

Each patient was classified according to TCM Syndrome Differentiation as having Cold Syndrome type, Heat Syndrome type, severe blood stasis (SBS) type, and mild blood stasis (MBS) type of UAP. Garlicin 60 mg or nitroglycerin 5 mg was given to the two groups respectively by intravenous drip for 10days as one therapeutic course. The curative effect was evaluated by symptomatic changes and electrocardiogram. The effective rates as well as indexes such as blood lipid, lipoprotein, apolipoprotein, and granule membrane protein-140 (GMP-140) were compared between groups and types. Results: Garlicin and nitroglycerin group did not differ significantly in effective rate, while that of Garlicin group was higher for the Cold Syndrome type than that of Heat Syndrome type (P < 0. 01 ). The high density lipoprotein/low density lipoprotein ratio and apolipoprotein A- I level rose markedly in the former type (P < 0. 05), while an opposite trend was seen in the Heat Syndrome type. Garlicin was more effective in the SBS type than that in the MBS type, and it markedly decreased GMP-140 in the MBS type. Conclusions: Garlicin is effective in UAP, especially the Cold Syndrome and SBS types. Its mechanism may involve improving blood lipid levels and inhibiting platelet activation.展开更多
