Abstract
Serum lipids and lipoproteins in 77 patients with arteriosclerosis obliterans (ASO) and in 34 patients with thromboangitis obliterans (TAO) were analyzed in detail. The following results were obtained.
1. There were no differences in levels of cholesterol and triglyceride between ASO and TAO.
2. β-lipoprotein were increased in both diseases.
3. High density lipoprotein cholesterol, lecitincholesterol acyl transferase (LCAT) and apoprotein-A were decreased in both ASO and TAO.
4. Extra pre-β lipoproteins were positive in about 20% of patients with both ASO and TAO. There were no differences in its incidence between patients with these diseases and normal person.
5. There were no remarkable changes in the composition of HDL2 and HDL3 in ASO and TAO.
6. As to serum lipids and HDL-cholesterol, there were no differences between ASO and TAO.
7. HDL-cholesterol was lower in patients with aorto-iliac occlusion than that in patients with femoro-popliteal occlusion in ASO.
8. HDL-cholesterol was lower in patients with rest pain or gangrene than that in patients with intermittent claudication in ASO.
9. Level of HDL-cholesterol in ASO patients with past history of myocardial infarction or cerebral vascular disease were lower than that in patients without those.
