Abstract
In order to investigate various influences to serum levels of apoproteins in healthy adults, we applied box-plots which are fundamental methods of exploratory data analysis and robust regression analysis. Serum concentrations of apoprotein A-I, A-II, B, C-II, C-III and E were measured by a single radial immunodiffusion method. The subjects consist of 179 males and 60 females aged 30-69 who are the staff and the retirees of Hiroshima University. The following results were obtained: 1. The levels of apoprotein A-II (aged 40-49), B (aged 30-39), C-II (aged 40-49) and C-III (aged 30-39, 40-49) in male were significantly higher than those in female. 2. It was observed that the levels of apoprotein-B, C-II and C-III in male, and A-II, B and E in female elevated with age. 3. Drinkers had higher levels of apoprotein A-I, A-II and C-III than non-drinkers in male. 4. Cigarette smokers had higher levels of apoprotein C-II and C-III than non-smokers in male. 5. Overweight adults had higher levels of apoprotein A-II, B, C-II, C-III and E in male and apoprotein-E in female than adults who are not overweight.
