Research on the general pharmacology of supramolecular drug CCP / 肿瘤研究与临床

ABSTRACT

Objective To investigate the side effects of a new supramolecular drug-platinum compound CCP on the cardiovascular system,respiratory system and neuropsychological system of healthy rat.Methods After abdominal anaesthesia with 4.0 ml/kg of 10%chloral hydrate.the rats were injected with10,20,40 ms/ks CCP respectively,and then the life indexes,including blood pressure,heart rate,electrocardiogram,respiratory rate and depth were recorded through single femoral and tracheal intubations and so to non-anaesthesia rats.Glucose injection was chosen as negative control and carboplatin(15 mg/kg)as positive control.Results After venous injection with CCP,glucose injection and carboplatin as the dosages as above respectively,the blood pressures of the tested rats are from(57.8±14.1)mm Hg to(86.2±8.1)mm Hg,heart rates are from(250.9±95.4)times/min to(356.7±47.7)times/min,respiratory rates are from(59.3±17.7)times/min to(95.7±26.0)times/min.No obvious changes of blood pressure,heart rate and respiration were observed after drug injection,t values are(0.02～1.96),(P＞0.05).Once of sporadically ventrieular premature beat was recorded in one rat of CCP and earboplatin groups and it is not dosage-dependent.There is no side effect of 40 ms/ks CCP in neuropsychological system and daily activity of non-anaesthesia rats.Conclusion CCP injection is safe in rat and there is no obvious change observed in the cardiovascular system,respiratory system,neuropsyehological system of healthy rat.
