[Change in the absorptive capacity of macrophages from different organs after administration of hydrocortisone].

Two, twenty-four and 48 h after hydrocortisone treatment in a dose of 125 mg/kg bw the blood clearance rate for colloidal carbon particles in rats turned to be 2, 2.1. and 1.6 times less whereas that for 51Cr-SRBC in CBA mice 2.1, 2.2 and 1.7 times less as compared to untreated controls. Within 24 and 72 h after hormone injection the efficacy of red blood cell uptake by Kupffer cells decreased 1.35 and 1.8 times whereas the similar uptake by lung or spleen macrophages changed but insignificantly and that by bone marrow cells was even greater than in controls. Toward the 5th day after zymosan treatment the uptake capacity of Kupffer cells was the greatest whereas the plasma 11-OHCS content was 1.3-fold less versus the control values.
