Previously, we have reported a novel proliferative action of pancreatic group I phospholipase A2 (PLA2-I) via a specific binding site in Swiss 3T3 fibroblasts, vascular smooth muscle cells, and… Expand
Antihepatotoxic principles of Atractylodes rhizomes.
Extracts of various samples of the crude drug prepared from Atractylodes rhizomes exhibited antihepatotoxic activity by in vitro assay methods using carbon tetrachloride- and galactosamine-induced… Expand

A wasp venom, mastoparan, rapidly increased the cytosolic free Ca2+ concentration ([Ca2+]i) and activated phosphorylase in rat hepatocytes in a concentration‐dependent manner. Mastoparan could… Expand
Assay method for antihepatotoxic activity using carbon tetrachloride induced cytotoxicity in primary cultured hepatocytes.
Conditions were examined to devise an IN VITRO assay method for antihepatotoxic activity using carbon tetrachloride-induced lesion in primary cultured mouse and rat liver cells. Utilizing 24… Expand
Assay method for antihepatotoxic activity using galactosamine-induced cytotoxicity in primary-cultured hepatocytes.
Conditions were investigated to devise an in vitro assay method for antihepatotoxic activity using galactosamine-produced injury in primary-cultured mouse and rat liver cells. Employing 1.5-h… Expand

Garlic constituents, the volatile oil, alliin, S-allylmercaptocysteine (ASSC) and S-methylmercapto-cysteine (MSSC) were subjected to assay for their antihepatotoxic activity using the IN VITRO and IN… Expand
GTP‐binding proteins in human platelet membranes serving as the specific substrate of islet‐activating protein, pertussis toxin
Two GTP‐binding proteins serving as the specific substrate of islet‐activating protein (IAP), pertussis toxin, were purified from human platelet membranes as heterotrimers with an αβγ‐subunit… Expand
