It has been established previously that low density lipoprotein (LDL) incubated with cultured endothelial cells, smooth muscle cells, or macrophages undergo a free radical-catalyzed oxidative modification. This modification involves lipid peroxides and extensive structural changes in the LDL molecule. The oxidatively modified LDL inhibits the motility of the mouse resident peritoneal macrophages, yet lysophosphatidylcholine in oxidized LDL acts as a chemotactic factor for circulating human monocytes. The present study demonstrated that the stimulation of human mononuclear cells with phorbol myristate acetate (PMA) results in an increase of oxidized LDL, which was assayed by LPO-KIT (obtained from Kyowa Hakko Inc.) in the culture medium. The medium containing oxidized LDL did not exhibit a chemotactic for human monocytes, but inhibited the chemotactic responses of monocytes to the N-formyl peptide and aortic extract.<br>These findings suggest that circulating monocytes may play a role in the subendothelial space by some chemotactic factors and become trapped in the splace due to the inhibitory effects of oxidatively modified LDL.

In the present study, effect of probucol (500mg×2, daily) on serum lipids and lipoproteins in S. F. family who showed typical familial hyper-cholesterolemia (FH) were investigated. The results were as follows:<br>1) The values of serum cholesterol (TC) before and after treatment of probucol were 348±14mg/dl and 220±12mg/dl, respectively. These data shows significant reduction of serum cholesterol after treatment of probucol. The percent of reduction of serum cholesterol was 36.4%. This value was significantly higher than the value (17%) in the other FH.<br>2) Though levels of LDL- and HDL-C were decreased after treatment of probucol, LDL-C level was markedly decrease in S. F family as compared with other FH. Reduction of HDL-C after treatment of probucol was not significant difference between in S. F family and other FH.<br>3) Total biliary lipids after treatment of probucol increased from 68.8μmol/ml to 141.9μmol/ml in a patient of S. F family. Level of bile acid increased after treatment of probucol, especially, in this case. On the other hand, the change of biliary lipids after treatment of probucol was not seen in other FH.<br>From these data, though mechanism of marked reduction of LDL-C in S. F family after treatment of probucol was still unclear, metabolism of cholesterol to synthesis of bile acid might have especially involved to marked reduction of serum LDL-C in S. F family.

It would be important to study the characteristics and the action of "dentured" or "modified" LDL in atherogenesity. We investigated whether modified LDL was formed in normal human and what effect this LDL had on human arterial smooth muscle cells in culture.<br>Incubation of plasma prepared from normal human was performed at 37°C for 6 hours. Thrombin was added to both of incubated plasma and also non-incubated plasma obtained from each subject in order to remove fibrin. Lipoproteins (VLDL, IDL, LDL and HDL) were ultracentrifugally isolated from each serum.<br>LDL obtained from incubated plasma had faster mobility than that from non-incubated plasma on agarose-gel electrophoresis. Lipids-composition (TC, TG, PL and Ch-ester) was altered in LDL after incubation. These alterations of LDL might be induced by lipid transfer protein. In this way, LDL obtained from normal human was modified.<br>DNA synthesis of human arterial smooth muscle cells (SMC) increased in the culture with LDL addition. This action of LDL was dose-dependent manner. DNA synthesis increased in the culture with modified LDL more than that with native LDL.<br>These data indicated that LDL obtained from normal human was easily modified and modified LDL influenced DNA synthesis of cultured arterial SMC.

30才,男性で5~6才頃から黄色腫を有し,著明な高コレステロール血症を呈した症例の家族検診,および培養線維芽細胞の検討成績から家族性高コレステロール血症ホモ接合体と診断した症例を報告する.家族検診の脂質検査では, 11例中9例に高コレステロール血症がみられ,そのうち, 8例にIIa型高脂血症がみられた.また,本症例の弟に著明な黄色腫が認められた.一方,心電図所見では, 1例に虚血性変化がみられた.培養線維芽細胞の検討では,本症のアセテートからステロールへの合成能が,正常人培養線維芽細胞に比べ約18倍高い.また,本症例細胞のHMG-CoA reductase活性は,正常人細胞と比べ約15倍高い.さらに,正常人細胞では,培養液をリポ蛋白deficient mediumにすると,細胞内HMG CoA-reductaseの酵素誘導がおこり増加するが,本症例では全く誘導がみられない.以上の結果から, LDLレセプターを直接測定していないが, Goldsteinらの提唱しているLDLレセプターの完全欠損症,すなわち,家族性高コレステロール血症ホモ接合体の症例であることを証明しえた.本症例の治療成績では,クロフィブレートやコレスチポールに全く抵抗を示し,他の強力な治療法を行なう必要があると考えられる.

The lipid levels of serum and lipoproteins were examined in eleven patients with myotonic dystrophy (MD) and ten normal subjects. Hyperlipoproteinemia was seen in six patients, including type IIb of three patients, type IIa of two and type V of one. Total cholesterol (C) and triglyceride (TG) levels of serum and lipoproteins in MD were not significant. TG/C ratio of lipoproteins in MD were not so high compared with normals.<br>The mean age of the patients with hyperlipoproteinemia was significantly higher than that of normolipoproteinemia. The correlation coefficients between age and lipid levels of serum and lipoproteins were examined. The age was positively correlated to serum C and VLDL-TG levels. Further, in the MD patients except for case 1 with type V hyperlipoproteinemia, the age was positively correlated to LDL-TG and LDL-C levels, and negatively correlated to HDL-TG levels.<br>In conclusion, the LDL levels increased and the HDL levels decreased with age in MD. These results suggest that the abnormalities of serum lipid metabolism is one of the characteristic changes in MD.

Diabetes mellitus is frequently complicated with atherosclerosis. PWV (pulse wave velocity) is an indicator for the sclerotic change of thoratic and abdominal aorta. We studied the relation between PWV and lipid metabolism in diabetics.<br>The subjects who took part in this study were 54 diabetics who were aged from 50 to 59 years old and had a duration of illness over 5 years. Fasting blood sugar level and the concentration of glycosylated hemoglobin (HbA₁) were measured. Serum total cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDL-C), apo B and apo A-I were measured by enzymatic methods and SRID, respectively. PWV was measured by the methods of Hasegawa, et al.<br>We concluded that (1) PWV increased in poorly controlled diabetics (FBS 180mg/dl) more than in well controlled diabetics (FBS 119mg/dl), and (2) PWV had significant positive-relation to serum TC, TG, apo B, apo A-I and apo B/A-I ratio, and had significant negative-relation to HDL-C.<br>According to these data we should improve not only glucose metabolism but also derangement of lipid metabolism.

ミトコンドリア遺伝子3243A-G変異を呈するミトコンドリア糖尿病は遺伝子異常が同定された糖尿病の中では最も頻度が高い.低身長,やせの体型を呈し,糖尿病診断時年齢が比較的若年であり,糖尿病の母系遺伝を認め,感音性難聴等が合併する頻度が高いと言われているが,日常診療で見過ごされている例も少なくない.今回我々はミトコンドリア遺伝子3243A-G変異を呈したミトコンドリア糖尿病の3症例を経験した.その3症例は全て軽度~高度の感音性難聴の合併を認めたが,肥満の症例や糖尿病の母系遺伝が明らかではない症例があり,その臨床像は陽性,陰性所見が混在していた.ミトコンドリア糖尿病の臨床像は多彩ではあるが,糖尿病に加えて感音性難聴や難聴の家族歴を有している症例には,ミトコンドリア遺伝子変異の検査等の積極的な検索を行う事が望ましいと思われた.

Three dysbetalipoproteinemic subjects with the E 2/2 homozygous phenotype were analysed serum lipoproteins and serum apolipoprotein E and B levels. Two subjects were normocholesterolemic and one was hypercholesterolemic (type III hyperlipoproteinemia). A patient with type III phenotype had cholesterol-rich VLDL, although the other two normocholesterolemic subjects didn't have it. Both normo- and hypercholesterolemic subjects had elevated levels of serum apo E and a reduction in serum apo B. Therefore, serum apo E/apo B ratio of a patient with type III phenotype was extremely high as compared with other lipoprotein disorders. These ratio of normocholesterolemic dysbetalipoproteinemia was also high as compared with those except for type V hyperlipoproteinemia. It is suggested that dysbetalipoproteinemia might be easily caught in general population by screening examination of serum apo E/apo B ratio.

In the present study, the effect of probucol (500mg×2, daily) on serum lipids and lipoproteirs level were studied in 9 patients with familial hypercholesterolemia (FH) during 3-4 months. The diagnosis of FH was established according to the criteria both of Fredrickson et al and of Makuchi et al. Thickness of Achilles tendon was over 9mm in all patients and the xanthomas were observed in 4 of 9 patients.<br>Before and 3-4 months after treatment of probucol the measurement of serum triglyceride (TG), total cholesterol (TC) and apolipoprotein (Apo) A-I and A-II were made. At the same time, serum VLDL, LDL, HDL₂ and HDL₃ were separated by successive ultracentrifugation. Thereafter, TG, TC and protein of each lipoprotein fraction were measured.<br>TG and TC were determined by enzymatic method, Apo A-I and A-II were done by single immunodiffusion assay, and protein was done by dye-binding method.<br>All data were expressed as mean ±S.E. and statistically analized by Student's t-test.<br>The results were as follows:<br>1) VLDL-TG levels were slightly increased, although no significance was found between VLDL-TG level before and after treatment.<br>2) The levels of serum TC were 388±37mg/dl and 308±28mg/dl (-21%, p<0.05) before and after probucol administration, respectively. LDL-cholesterol (LDL-C) levels decreased from 325±37mg/dl before treatment to 262±32mg/dl (-19%, p<0.05) after treatment. HDL-C values significantly decreased from 42±5mg/dl to 26±4mg/dl (-38%, p<0.01), and especially HDL₂-C showed significant fall (-48%, p<0.01).<br>3) Serum Lecithin: Cholesterol Acyltransferase (LCAT) activities were not changed.<br>4) The concentrations of Apo LDL decreased from 139±18mg/dl to 106±17mg/dl (-29%), but it was not significant statistically. Apo A-I levels decreased significantly from 92±10mg/dl to 66±10mg/dl (-28%, p<0.01). On the other hand, Apo A-II levels were unchanged.<br>These observations suggested that probucol would be a useful drug to improve serum and LDL cholesterol levels in FH. However, we should take care to use this drug because of its effect on HDL metabolism.

It is thought that multi-factors may relate to the occurence and exaggeration of arterial sclerosis in diabetes mellitus. We pointed out the calcification of peripheral arteries in the legs on X-ray photographs as a sign of arteriosclerosis, and studied its prevalence in diabetics and nondiabetics. Furthermore, in order to clarify what correlates with the arteriosclerosis, we analysed the laboratory data and studied the differences between the diabetics with or without the peripheral arterial calcification.<br>We concluded that the incidence of the peripheral arterial calcification in diabetics (32%) was twofold higher than that in non-diabetics (16%).<br>It was clarified that the incidence of the calcification increased significantly in diabetics who had insulin treatment as compared with those who had oral agents or only diet therapy. Similarly, it was significantly higher in diabetics who were complicated with proliferative retinopathy than those who had simple or no retinopathy. And also, diabetics with longer duration of illness had significantly high incidence of the calcification as compared with those with shorter duration.<br>It was relatively higher frequency in diabetics who had hypertention and were controled poorly than those who had normotention and were controled well, respectively, but there was no significance between them.<br>There were no relationships between the peripheral arterial calcification and obesity, serum concentration of lipids, ischemic changes on ECG and aortic arch-calcification in diabetics.<br>These results suggested that the peripheral arterial calcification might relate to the metabolic derangement in diabetes mellitus.

Diabetic autopsy cases were collected from the Annual Report of Pathological Autopsy Cases published by Japanese of Pathology for the year 1976-1978. 2089 primary diabetic cases were collected and the cause of death and pathoanatomical findings in various organs were analysed in these primary diabetic cases, and following results were obtained.<br>1) The main causes of death were cardiovascular diseases (43.1%), malignant neoplasma (22.6%), infections (16.2%), diabetic coma (1.9%) and hypoglycemia (0.3%).<br>2) In cardiovascular diseases, the leading cause was diabetic nephropathy (15.6%), followed by cerebral (14.6%) and coronary (10.5%) artery disease.<br>3) The frequency of arteriosclerotic cardiovascular diseases and malignant neoplasmas as cause of death increased with age. Diabetic nephropathy appeared as a cause of death in 3rd decade and the leading cause of death was diabetic nephropathy in 3rd decade (52%) and 4th decade (32%), and over 5th decade decreased with age. Cerebral vascular and coronary artery diseases increased with age and cerebral vascular disease was the leading cause of death over 6th decade.<br>4) In pathoanatomical findings, the frequencies of glomerulosclerosis, myocardial infarction, cerebral infarction and homorrhage were 40.9%. 17.2%, 15.6% and 7.0%, respectively. Myocrdial infarction and cerebral infarction were found in 4th decade and increased with age, while cerebral hemorrhage decreased over 6th decade with age. Diabetic glomerulosclerosis was found in the cases of 2nd decade and high frequencies of glomerulosclerosis were found in all decade and it was higher than those of other vascular lesions.<br>These results showed the characteristics in the causes of death of diabetics in Japan are a lower incidence of coronary artery disease and a high incidence of diabetic nephropathy.
