Abstract: | An ophthalmofunduscope was used to investigate arteriosclerosis among villagers aged 20–40 yr old in two rare earth areas
in Ganzhou, Jiangxi Province. It was noted that the occurrence of arteriosclerosis of the fundus aculi was significantly high
(P < 0.05-0.01), the detection of serum cholesterol (CHO) was remarkably increased (P < 0.01), and the level of IgM was also elevated. However, high-density lipoprotein (HDL) remained at a low level. The effect
of taking rare earth elements (REE) could be direct or indirect, thus causing an increase in cholesterol and interfering with
the synthesis of high-density lipoprotein. Furthermore, rare earth could also cause immunogenic damage to the vascular wall.
All of these could facilitate the formation of arteriosclerosis. |
