WebBrCCl3-lethality was increased 5-fold by CD as indicated by the decreased LD50. The results suggest that CD-induced BrCCl3 toxicity is manifested both in the form of hepatotoxicity and lethality and since the hepatic functional status is greatly compromised, the CD potentiated hepatic failure is related to lethality. Publication types WebLiver spermidine N1-acetyltransferase was elevated at 2, 6, and 24 hr after exposure to a high dose of BrCCl3 alone as compared to treatment with a low-dose combination of CD …
