[Effects of aminoguanidine sulfate on hepatic and blood levels of histamine after partial hepatectomy in rats].

Known as a specific inhibitor of histaminase, amino-guanidin sulfate has been administered subcutaneously to Wistar rats immediately after partial hepatectomy, then once in 16 hours until 80 hours. It has thus provoked: an initial rise of the hepatic and blood rates of histamin, which is transient and reaches its apex 6 hours after the operation; then, a new rise of these rates, which lasts and even is, in percentage, maximum at 72 hours. Therefore, amino-guanidin sulfate is available to estimate the influence of the endogenous histamin upon liver regeneration.
