The influence of some biogenic amines and amine-receptor-blocking drugs in the growth rate of human colorectal carcinomas propagated as s.c. xenografts in immune-deprived mice was studied. In mice treated with adrenaline, a beta-adrenergic agonist, the growth of xenografts was suppressed for 2 days, after which growth was resumed at a rate similar to that in control animals. Treatment with the phosphodiesterase inhibitor theophylline prolonged the adrenaline-induced inhibition of growth. Treatment with the beta-adrenergic antagonist sotalol or practolol increased the rate of tumour growth. Treatment with either serotonin or the histamine H2-receptor agonist Dimiprit had no effect on tumour growth rate. However, the antiserotoninergic drug BW 501C and the histamine H2-receptor antagonist cimetidine each caused short-term suppression of tumour growth.
研究了某些生物胺和胺受体阻断药物对在免疫缺陷小鼠中作为皮下异种移植物生长的人结肠直肠癌生长速率的影响。在用β-肾上腺素能激动剂肾上腺素治疗的小鼠中,异种移植物的生长被抑制了2天,之后以与对照动物相似的速率恢复生长。用磷酸二酯酶抑制剂茶碱治疗可延长肾上腺素诱导的生长抑制。用β-肾上腺素能拮抗剂索他洛尔或心得宁治疗可提高肿瘤生长速率。用5-羟色胺或组胺H2受体激动剂二甲双胍治疗对肿瘤生长速率没有影响。然而,抗5-羟色胺能药物BW 501C和组胺H2受体拮抗剂西咪替丁均引起肿瘤生长的短期抑制。
