Methods:We compared it with Metoclopramidum injection or imported Granisetron injection in 106 patients with cancer using the method of self crossover study. Results:It is shown that (1) the domestic and imported Granisetron had similar antiemitic efficacy (86.8% V 86.6%) and side effective rate (23.5% V 29.4%);(2) the effective rate of domestic Granisetron (86.8%) was significantly higher than that of Metoclopramidum (50.0%, P <0 001), and there was no significant difference in Metoclopramidum (50.0%, P <0 001),and there was no significant difference in side effect rates between Granisetron and Metoclopramidium.Conclusions:The domestic Granisetron injection is an effective and safe antiemetic drug.展开更多
目的探讨甲钴胺对脑缺血再灌注大鼠脑组织细胞色素C表达的影响。方法选择Wistar大鼠132只,随机分为假手术组(24只)、模型组(27只)、尼莫地平组(27只)、甲钴胺低剂量组(27只)、甲钴胺高剂量组(27只)。采用改良线栓法栓塞大脑中动脉3h制...目的探讨甲钴胺对脑缺血再灌注大鼠脑组织细胞色素C表达的影响。方法选择Wistar大鼠132只,随机分为假手术组(24只)、模型组(27只)、尼莫地平组(27只)、甲钴胺低剂量组(27只)、甲钴胺高剂量组(27只)。采用改良线栓法栓塞大脑中动脉3h制作大鼠脑缺血再灌注模型;分别于6、12、24h用TUNEL法检测大脑皮质细胞凋亡、Western blot检测大脑皮质细胞色素C蛋白的表达。结果尼莫地平组、甲钴胺低、高剂量组6、12、24h阳性细胞数较模型组明显降低(P<0.01);模型组6、12、24h细胞色素C表达较假手术组明显升高(P<0.05,P<0.01);尼莫地平组、甲钴胺低、高剂量组6、12、24h细胞色素C表达较模型组明显降低(P<0.05,P<0.01);甲钴胺高剂量组6、12h细胞色素C表达较甲钴胺低剂量组明显降低(0.466±0.046 vs 0.617±0.033,P<0.01;0.163±0.081 vs 0.552±0.132,P<0.05)。结论甲钴胺对脑缺血再灌注损伤保护机制可能与抑制细胞色素C蛋白表达有关,以高剂量效果较好。展开更多
