Effect of radiodetoxified endotoxin and trace elements on reticulo-endothelial system damaged by ethanol in rats.

For the demonstration of RES activity 99-mTc labelled nano-albumon micro-colloid solution (prepared by OSSKI, Budapest, Hungary) was injected into the prepared jugular vein of narcotized rats and the clearance rate was investigated. The effects of various materials have been observed on RES in vivo. Continuous consumption of 20% ethanol solution for 15 weeks decreased the phagocytic activity. One hundred microgram/100 g body weight (i.v.) of the radio-detoxified endotoxin preparation (RD-LPS, TOLERIN) prepared from Escherichia coli endotoxin by 60Co-gamma irradiation (150 KGy) increased the granulopectic activity of RES of intoxicated animals. The preparation containing trace elements also increased the former activity and the treatment consisting of the use of both trace elements and RD-LPD was as effective as the RD-LPD per sc.
