ABSTRACT
Objective To observe the clinical effect of Herba Houttuyniae Injection in treating senile pneumonia and to explore its possible mechanism. Methods Sixty-five patients were randomly divided into two groups. The control group was treated with conventional western therapy (CWT), while the treatment group was treated with CWT plus Herba Houttuyniae Injection. The changes of serum cytokines, IL-2 and TNF-?, before and after treatment were observed. Results the total effective rate of treatment group is 94.3%, while that of the control group is 83.3%. The difference of the total effective rate between the two groups was significant(P
ABSTRACT
Objective:To investigate the curative effects of Herba houttuyniae injection by spray inhalation and by intravenous drip on lower respiratory tract infection and compare effects.Methods:62 patients with lower respiratory tract infection were divided into the intravenous drip group, spray group 1 and 2 according to sequential trial. The intravenous drip group was treated with Herba houttuyniae injection by intravenous drip, once a day. The spray group 1 and 2 were treated with Herba houttuyniae injection by spray inhalation, once a day and three times a day, respechively.Results:The cure rate of the intravenous drip group was 48% and the total effective rate was 90.48%. The cure rates and total effective rates of the spray group 1 were 25% and 60%. The spray group 2 was 43% and 85.07%.Conclusion:The curative effects of Herba houttuyniae injection by intravenous drip and by spray inhalation (three a day ) on lower respiratory tract infection are similiar and better.
ABSTRACT
AIM: To observe the effects of herba houttuyniae injection, a chinese medicine, on myocardial injury induced by endotoxin and to explore the possible mechanism. METHODS: 24 male SD rats,weghting (250?30) g, were randomly divided into three groups: normal control group(NC, n=6), endotoxin group (ET, n=6), herba houttuyniae injection puls endotoxin group (HHI+ET, n=6) and herba houttuyniae injection group (HHI, n=6). Heart was isolated from rats and perfused on Langendorff apparatus with Krebs-Henseleit (KH) buffer (Saturation 95%+5%CO_2) at a constant pressure (8.33 kPa) and temperture(37℃). The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) content of efflux from coronary artery were measured at certain time points (0 min, 20 min, 50 min, 80 min). The ventricular function, the concentration of nitric oxide (NO) and the activity of succinate dehydrogenase (SDH) in myocardial tissue were also observed. RESULTS: Compared with ET group, the percentage recovery of the product of left ventricular pressure difference and heart rate [(LVSP-LVEDP)?HR], LVDP,+dp/dt_(max) were all increased apparently in HHI treatment group. The activities of SOD, SDH and the concentration of MDA, NO in HHI treatment group were close to that in normal control group. CONCLUSION: Herba houttuyniae injection protects myocardium against injury induced by endotoxin. It may be related to decrease in the level of NO, the strength of antioxidation, the stability of enzyme activities and the improvement of energy metabolism in myocardium.
