RESUMO
Objective To evaluate the muscular irritation,hemolysis and sensitization of Aripiprazole Injection.Methods The local muscle irritation of Aripiprazole Injection was observed through sc injection on quadriceps femoris in rabbits.The 2％ red blood cell suspension in the blood of rabbit was used to check whether Aripiprazole Injection could cause the reaction of emolysis and erythrocyte agglutination.The method of systemic active allergic test (ASA) was used to evaluate the effect of Aripiprazole Injection on allergic reaction in Guinea pigs.Results No evidence ofhemolyzation and aggregation on rabbit erythrocyte in vitro was observed after Aripiprazole Injection treatment.Test substance was sc injected by single or multiple doses for 7 d,both of them had muscular irritation on New Zealand rabbits,the major pathologic change was the degeneration and necrosis of myofibers,myofibers broke apart and disappeared,lots of inflammatory cells immersed.After drug withdrawal,muscular irritation was recovered.No allergic reactions on Guinea pigs in vivo were observed at the low dose of 3.75 mg and the high dose of 7.5 mg.Conclusion Aripiprazole Injection has no hemolyzation and sensitization,but may cause muscle irritation at higher concentration.
RESUMO
Objective To investigate the synergism and attenuation effects of Pini Pollen on paclitaxel and cisplatin ( TP) chemotherapy in model mice. Methods Forty-eight model nude mice with H456 cell line xenograft were divided into 8 groups: model group, TP chemotherapy group, Pini Pollen (150, 300 and 600 mg/kg) group and TP chemotherapy plus Pini Pollen (150, 300 and 600 mg/kg) group. The tumor inhibition rates, body weight, food intake, hematology and blood biochemistry indexes were selected to evaluate the synergism and attenuation effects of intragastric administration of Pini Pollen (150,300,600 mg/kg) on TP chemotherapy. Results Compared with the TP chemotherapy group, the tumor inhibition rates, body weight, food intake, white blood cell count were increased and liver and kidney function damage were alleviated significantly in the TP chemotherapy plus Pini Pollen groups. Conclusions Pini Pollen has a significant synergism and attenuation effects on TP chemotherapy.
