[Studies on background of gamma-GTP abnormality in human multiphasic screening. (Part 2): Principle component analysis by SAS statistic package for computer analysis].
In previous studies we reported that the abnormality of the gamma-GTP level was found not only in hepatobiliary diseases but also in obesity and ingestion of alcohol in healthy individuals. In relation to this results, the present study deals with the relationship between abnormal gamma-GTP level in serum on the one hand and obesity and ingestion of alcohol on the other hand on the basis of test data for 1493 cases (1256 male cases, 237 female cases) who were examined in the short-term human dry dock managed by the Fukuoka University Hospital. To observe how results of various measurements including the degree of obesity and the amount of alcohol ingested exert effects on one another, principle component analysis was done by means of SAS statistic package for computer analysis. In men, as the first principle main components, obesity rate, Hb, Ht, RBC, GPT, gamma-GTP, LAP, GOT, triglyceride and total protein were extracted. As the second main principle components, alcohol, gamma-GTP, MCH, MCV, and HDL were extracted. Theses result demonstrate that the obesity is accompanied by variations in Hb, Ht, RBC and triglyceride and that digestion of alcohol is accompanied by variations in MCH, MCV and HDL in male. In women, components related to erythrocyte and transaminase along with the degree of obesity were extracted as the first main principle components, and principle components related to erythrocyte and alcohol were extracted as the second main components. In either case, alcohol and gamma-GTP were not included.
