Lipids metabolism during prolonged fasting (10-days complete fasting) has been studied in 23 psychosomatic patients (9 male and 14 female, average 29.2 y. o.), who had no metabolic disease.During the fasting period, serum F.F.A. and Cholesterol levels significantly elevated (p<0.001).In the lipoprotein fraction, LDL-cholesterol and LDL-triglyceride (d: 1.006-1.063) significantly elevated by fasting (p<0.001), but VLDL-triglyceri de (d;<1.006) decreased (p<0.05).The increase of LDL reflected the increase of LDL2-fraction (d; 1.019-1.063), and this was related to thyroid hormone levels. T3 levels decreased during prolonged fasting (p<0.01).It was considered that increase of LDL was related to the decrease of LDL-receptor activity which was dependent on T3-levels.

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.

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.

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.

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.

I.カエル水晶体の含水率とクリスタリン組成 水晶体周辺部の含水率は70%前後でありゾル状態であった。中心部に移行するに従って含水率の低下が進み、ゾルからゲル状態への層の移行がみられた。最終的に核では20%前後と著しい含水率の低下がみられ、核は事実上鋼球体であった。水晶体構造蛋白質(α、β、ρ、γ-クリスタリン)の組成は含水率の低下即ち中心部に移行するに従って、α、β、ρ、-クリスタリンの減少とγ-クリスタリンの増加が認められた。さらに、中心部ほど不溶性クリスタリンの増加がみられた。II.水晶体の顕微鏡観察 水晶体の物性は周辺部と核では著しい相異があり、凍結切片を作製するさい核は粉状に粉砕されてしまう。他の方法による切片の作製も同様容易ではなく、顕微鏡観察による力学的ストレスの解析にはなお検討する必要が残った。III.熱力学的ストレスによる影響 加熱によ変性を調べると50℃より表面の白濁が進行し、その後完全に白濁変性する。しかし、この白濁は中心部では認められず透明な状態を維持している。一方、-80℃で凍結後、室温に戻すと、水晶体周辺部は依然透明であるが核は白濁変性を起こした。この傾向はトノサマガエルより食用ガエルでみられ、また大きい水晶体ほど白濁の程度が著しかった。変性の起こらない温度領域で低温高温の反復処理(0と40℃、それぞれ5分を一日反復負荷)を行ったが顕著な変化は観察されなかった。IV.超音波による影響 超音波(1MHz、8w/cm^2)処理を20℃で5分行うと周辺部と核の中間層に気泡形成が認められ、この中間層に最も強い振動の力学的ストレスの影響が現われた。以上、水晶体を核、中間層および周辺部の3層に分けて考察することができた。含水率の高い水晶体周辺部はゾル状態であり振動などの力学的ストレスに対して柔軟に対応できる反面熱に弱い構造となっている。中心部の核は含水率を極端に下げて蛋白質の高密度化を達成して熱や力学的ストレスに対処できる丈夫な構造になっている。ところが中間層は周辺部と核の両者の特徴を兼ね備えてはいるが、相反する性質が混在するが故にかえって力学的ストレスに対応しきれていない可能性がある。カエルの白内障はまさしくこの領域に集中していることから、力学的ストレスとの因果関係が示唆された。

A 9-year-old neutered female Miniature Dachshund had undergone lobectomy of the left frontal lobe for lung carcinoma followed by nine post-operative doses of carboplatin chemotherapy(250 mg/m2, every 3weeks). The dog was referred to the Japan Animal Referral Medical Center (Nagoya), because of lung masses in the opposite right middle and posterior lobes. Whole body contrast-enhanced computed tomography(CT)was performed and revealed lung solitary tumors in the relevant areas. No abnormal findings were observed in other lobes or intrathoracic lymph nodes. Since the possibility of metastatic lesions of lung carcinoma incompletely removed in the previous surgery was considered, we performed CT again on day 45 for evaluation of the new tumor progression. The size of both tumors increased, and right middle and posterior lung lobectomies were carried out on day 53. There were no adhesive lesions around the tumors, carcinomatous pleuritis, pleural fluid or hilar lymphadenopathy. While histopathology revealed high-grade lung adenocarcinoma with numerous mitoses, there was no evidence of intravascular invasion, suggesting complete resection. A tentative diagnosis of metastatic lung tumor(T2N0M1)was made. Adjuvant chemotherapy with carboplatin(250 mg/m2, for every 3 weeks)and piroxicam(0.3 mg/kg/3 days)was also given starting on day 21, and no evidence of recurrent lesions was observed on day 726 with a good health condition maintained. From these results, it is suggested that aggressive surgery plus adjuvant chemotherapy can be appropriate treatments for metastatic lung carcinoma.
