It has been observed in research on tumor-bearing rats, 51Cr-albumin or neocarzinostatin (NCS) conjugated with 51Cr-labeled styrene-co-maleic-acid polymer (SMA), which is called SMANCS, when injected, 1.3-3 fold intensification of drug accumulation was perceived after systolic blood pressure was increased from 100 to 150 mm Hg using angiotensin-II [61]. This evidence concerns the gene ALB and neoplasm.
