[Differences in the behavior of organic lesions, immunologic and metabolic parameters in 2 inbred strains of rats].
Two inbred rat strains were obtained by selective breeding and inbreeding: IR (isoprenaline resistant) and IS (isoprenaline sensitive). In addition to known differences between the two strains (1) other differences were found. As compared to IS strain, IR rats were more aggressive and showed more comfort behaviour in open field test. IR rats developed larger stress-induced gastric lesions but smaller heart lesions. They had larger spleen and thymus and more severe arthritis after Freund adjuvans administration. The two strains might be useful in studying the effects of drugs on various pathological processes. Their hybrids are being used to study interrelations between different genetic factors.
