Liver function influenced by drinking were studied in cases of a thorough physical examination. Objects of our study were 172 cases who entered in our clinic during past two years. 172 cases were divided into three groups. 1st group was 70 cases who had drunk less than 20 grams of ethyl alcohol a day, 2nd group was 49 cases who had drunk 20 grams a day and 3rd group was 53 cases who had drunk 40 grams a day.
GOT, GOT/GPT, γ-GTP, CHE and LAP were changed significantly with the increase of drinking as a result of study of these three groups. Especially it was thought that GOT/GPT, γ-GTP and LAP reflected most sharply the grade of alcoholic liver injury.
