title: [Relation of serum apolipoprotein B100 levels to lipids and apolipoproteins A I, A II, C II, C III and E levels in the middle and old age normal males in Chengdu area].
abstract: This study was conducted in 438 normal men aged 40-70. The age groups were: 40-44, 45-49, 50-54, 55-59, 60-64, and 65-70. The results showed that the serum apolipoproteins levels (mean+/- s, mg/L) were: B100 levels 742.5 +/- 165.8, A I 1301.2 +/- 219.9, A II 299.4 +/- 49.0, C II 42.7 +/- 21.4, C III 113.3 +/- 34.0 and E 38.7 +/- 8.2. The levels of serum apoB100 increased with age. The serum apoB100 levels in the 5th and 6th age groups were significantly higher as compared with the groups 1, 2, 3 and 4 (P < 0.05 and P < 0.05). The fasting serum mean TG (1.39 +/- 0.45 mmol/L), TC(4.79 +/- 0.82 mmol/L) and LDC-C(1.62 +/- 0.40 mmol/L levels in the groups 5 and 6 were significantly higher as compared with the groups 1, 2, 3 and 4 (P < 0.01). Serum apoC II, C III and E levels were significantly increased in the groups 5, 6 (P < 0.05). The correlation analysis indicated that there was a positive correlation of apoB100 with serum TG, TC, LDL-C, apoC II, C III and E respectively (P < 0.01); and a negative correlation with HDL-C levels (r = 0.1312); and apoB100 correlated negatively with apoA I (r = -0.0706). The results suggest that serum TG, TC, LDL-C, apoC II, C III and E are the main factors related with the serum apoB100 levels.
