title: Effects of small-intestinal factors on hepatocyte development and modification of chemical agent-induced hepatopathy in rat.
abstract: We have clearly shown by primary culture of hepatocytes that a promoting factor for proliferation of parenchymal hepatocytes appeared in the portal blood of rats which received 70% partial hepatectomy, and that such a liver-regenerating factor exists not only in murine small-intestinal mucosa, but also in bovine intestinal mucosa at all times. We also observed that in hepatopathy induced in rats by chemical agents such as CCl4 and D-galactosamine, intraperitoneal injection of the bovine small-intestine mucosal extract containing this factor suppressed the increases of GOT, GPT and other enzyme activities in the rats' serum and modified the hepatopathy. These results indicate that the in-vitro effects of these factors on hepatocyte cultures reflect those found in vivo on hepatopathy.
