附子不同炮制品灌胃Beagle犬的急性毒性研究

目的：探讨附子不同炮制品灌胃Beagle犬的急性毒性。方法：取健康、合格Beagle犬16只，按体质量随机分为空白组、刨附片组、炮天雄组和黑顺片组。以4 g生药/kg灌胃给药，实验前及给药后1 h、24 h和第3、7、14天测定体质量、耗食量、肛温、心电图及血常规、血生化。结果：3个实验组Beagle犬在给药后均精神萎靡，血液电解质有显著性差异，其中黑顺片组最明显；刨附片组犬的红细胞、血糖和甘油三酯有显著性差异；炮天雄组犬的淋巴细胞和血糖有显著性差异，而黑顺片给药后犬的淋巴细胞显著降低。结论：3个炮制品毒性大小依次为黑顺片>刨附片>炮天雄。

Acute Toxicity Study on Intragastric Administration of Different Processed Radix Aconiti Lateralis Praeparata Products to Beagle Dogs

This article was aimed to study the acute toxicities on intragastric administration of different Radix Aconiti Lateralis Praeparata processed products to Beagle dogs. A total of 16 healthy and qualified Beagle dogs were randomly divided into the blank group, Pao-Fu-Pian (PFP) group, Pao-Tian-Xiong (PTX) group and Hei-Shun-Pian (HSP) group according to the body weight. The intragastric administration of 4 g crude herb per kg was given. Before medication, 1 h, 24 h, and 3, 7, 14 days after medication, the body weight, food consumption, rectal temperature, electrocardiogram, blood routine and blood biochemistry were measured. The results showed that after medication, all dogs in three experimental groups were depressed. And there were significant differences in the electrolytes of blood. Among them, the HSP group was the most obvious one. The red blood cells, blood sugar and triglycerides of dogs in the PFP group had significant difference. The lymphocytes and blood sugar had significant difference of dogs in the PTX group. However, after the medication of HSP, the lymphocytes of the dogs were decreased significantly. It was concluded that the toxicity of three processed products followed the order of HSP > PFP > PTX.
