Abstract:
Purpose:To evaluate the different concentration of HCPT in rabbit blood and bladder tissue between intraarterial and intravenous penfusion groups.To indentify the probability of using HCPT as a new type of anti-tumor agent delivered by the intra-arterial pesfusion method for the treating of bladder cancer.Materials and methods:Group A:40 white female rabbits were divided into 2 groups(intraarterial and intravenous)and each was subdivided according to the time intervalsof bladder tissue sampling,of 5,15,30,60,120 minites after the drug delivering.Group B:16 white female rabbits equally divieded into 2 groups(intraarterial and intravenous)for dynamic blood sampling by the intervals of 5,15,30,60,120 minitus after the drug delivering.The intra-arterial method using an artifial bilaterial super-select internal iliac artery perfunsion model defined previouysly.The intravenous method was to deliver drugs via earmarginal vena of rabbit.1mg/kg as the concentration of the drug in bladder tissure was measured by reversed-phase HPLC.Results:The concentration of the drug in bladder tissue was significantly different between the intra-arterial and intionenous groups.Drug in the bladder tissue delivered by intra-artial method was 2.17,3.41,1.51,1.52,2.33 times as much as by intra-venous method.While drugs in blood by intra-venous method was 1.92,2.03,1.77, 1.92,1.40 times as much as by intra-arterial method.Conclusion:HCPT is suitable for trans- arterial perfusion for the treating of bladder cancer.
