説明

The Selye's granuloma pouch method of anti-inflammatory assay was improved by injecting nitrogen gas instead of air for making a subcutaneous pouch in the back of the rat. Croton oil inflamed exdation in the nitrogen-pouch was much greater in the exudate volume and apparently smaller in the variance of individual volume when compared with the croton oil exudation in the air-pouch. Accordingly, the precision of antiexudation assay was improved. It was further demonstrated that the previously reported formalin-filterpaper-pellet method could be additionally applied in the rats bearing the nitrogen-pouch exudation, so that the simultaneous measurements of anti-granulation and anti-exudation activities of the test compound were available. Structure-activity relations of various pregn-4-ene derivatives were reinvestigated by the above method, and it was concluded that anti-exudation activities of steroidal compounds did not necessarily corelate with their anti-granulation activities: antiexudation activity of progesterone was increased by 17α-hydroxylation but decreased by 21-hydroxylation, and the coexistence of 11β-OH and 21-OH was needed for the manifestation of granuloma inhibition and of adrenal and thymus involution.
