血必净注射液防治家兔应激性脏器损伤的研究

目的探讨血必净注射液对家兔应激性脏器损伤的保护作用及其机制。方法40只大耳白兔随机分为正常对照组、实验对照组、西药治疗组和血必净组。以浸水方法制成应激模型，制模后西药治疗组和血必净组分别注射冬眠合剂和血必净注射液，观察各组家兔给药后不同时间血清皮质醇（Cor）、血栓素A2（TXA2）、内皮素（ET）以及一氧化氮合酶（NOS）含量变化；并观察胃黏膜、肾上腺以及心肌细胞的病理变化。结果制模后家兔Cor含量显著升高（P〈0．01）；西药治疗组和血必净组含量均有所降低，两组间比较差异无显著性（P〉0．05）；西药治疗组和血必净组ET和TXA2含量均明显降低，NOS含量均明显升高，两组间比较差异具有显著性（P均〈0．05）。血必净组胃黏膜、肾上腺以及心肌的病理学变化改善明显优于西药治疗组。结论血必净注射液对于应激性脏器损伤具有良好的保护作用。

Experimental study of protective effects of Xuebijing injection(血必净注射液)on stress-induced organ damage in rabbit

OBJECTIVE: To investigate the protective effects of the integrated traditional Chinese and western medicine Xuebijing injection on stress-induced organ damage in rabbits. METHODS: Forty rabbits were randomly divided into four groups: the control group, the model group, the western medicine group, and the Xuebijing group. The stress-induced organ damage model was replicated by soak the rabbits in water, the animals in the western medicine group and Xuebijing group received injection of lytic cocktail and Xuebijing, respectively. The changes in cortisol (Cor), thromboxane A(2) (TXA(2)), endothelin (ET), nitric oxide synthase (NOS) were determined at different time points in all the groups. The pathologic changes of the gastric mucosa, the adrenal gland and the cardiac muscle cell were observed. RESULTS: The content of Cor increased significantly in model group (P<0.01). The content of Cor decreased in the western medicine group and Xuebijing group, the changes showed no significant difference between two groups (P>0.05). The contents of ET, TXA(2) decreased and NOS increased in Xuebijing group compared with the western medicine group, the differences were significant (all P<0.05). The pathological changes of the gastric mucosa, the adrenal gland and the cardiac myocyte were less marked in Xuebijing group, compared with the western medicine group, the difference was significant (P<0.05). CONCLUSION: Xuebijing has better protective effects on stress-induced organ damage.
