肉眼視できる最も少ない光量の100万分の一ほどの極く弱い光を検出する装置が開発され,その医学分野への応用も可能になった. このような弱い光では光子の流れは不連続で計測結果は電流としてではなく, 単位時間当りの光子数として表わされる.微弱な発光としては, 古くからホタルなどの luciferin-luciferase 反応によるものや, 発光蛋白質の分解により発光する生物種などが知られ, 生物発光と呼ばれている. 他方, luminol に代表される化学発光がある. 両者は励起分子が発光する点において同一である.この化学発光に属するものに一重項酸素の発光がある. 即ち, 励起状態の活性酸素である一重項酸素が基底状態の三重項酸素に遷移する時に光子を放出する. この性質を利用し生体試料中での一重項酸素の存在を知ることができる. ただし, 他にも発光種はあるので注意を要する.生体試料中での一重項酸素などによる発光は肉眼視できぬ極く微弱なもので極微弱発光と呼ぼれ, その中でも血液の発光のように極端に弱い発光を超微弱発光と称している.われわれは人の血液の超微弱発光の計測を行ない, 主として血漿に関して, 糖尿病や諸肝疾患で発光量が高いことを認めた. scavenger や発光スペクトルの分析からこれらの発光に一重項酸素の関与が示唆された.正常人でも喫煙すると血液の超微弱発光が増加することが見い出された. この現象は禁煙により消失することも判明した. また, タバコの煙自体も強い超微弱発光を示し, 一重項酸素がその発光に関与すると推察された.free radical や活性酸素は老化や疾患と関連して注目されているが, 臨床的には扱いにくい. その中で一重項酸素を超微弱発光として把える手段は有用であり, その実用例を紹介した.

The detecting ability of the photon counting system of single photoelectron counting method has been greatly improved and an equipment of this method, designed for biochemical and biomedical applications, was developed. The photomultiplier used in the instrument was of bialkali photocathode of 5cm diameter with the spectral responce nearly from 300nm to 660nm and of specifically low noise selected from hundreds of the same photomultipliers. The photomultiplier was cooled down to -20° in the equipment in the actual photon counting for the further reduction of the noise. All other possible electrical noises from the inside and the outside of the counting machine were eliminated or minimized. The sensitivity of the photon counting equipment reached the level high enough to permit the determination of extremely weak light emission like those of human blood and tissue samples. Thus, the first quantitative measurement, to our knowledge, of ultra weak chemiluminescence of human blood samples was performed with this instrument. The whole blood and plasma samples of normal subjects gave relatively low levels of light emission. On the contrary, the blood samples of patients with diabetes mellitus and with liver diseases showed significantly higher light emission levels. Of particular interest was of the blood of patients with obstructive jaundice and of severe hepatitis. The light emission of the blood samples of these disease was generally very high and in the levels allowing the spectral analysis of the emitted light.The analysis and the scavenger experiments indicated the contribution of singlet oxygen as the photon emitting entity in these blood samples.

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.

アルギニンによるインスリン分泌にはグルコースの存在が必要である. しかしアルギニンによるグルカゴン分泌にたいしてグルコースがどのように作用しているかは明らかではない. ラット膵灌流実験を行ない, グルコース, 0, 50,150,300mg/dlの存在下でアルギニン作用を検討した.アルギニン注入後2分のグルカゴン値はそれぞれ745±46, 2062±106, 3433±127,510±21pg/nlと増加し, その分泌パターンはグルコース濃度0, 50mg/dlでは1相性であり, 150,300mg/dlの条件下では2相性を示した. アルギニン注入によるインスリン分泌はそれぞれ10.7±1.6, 32.4±3.2, 39.0±3.3, 43.2±3.5ng/dlと増加し, 分泌パターンはグルコース濃度0, 50mg/dlでは1相性, 150,300mg/dlでは2相性を示した. この成績はアルギニンによるグルカゴン分泌にはインスリン分泌にたいするのと同様にグルコースの存在が必要であることを示唆している. 特に興味ある事実はグルコース濃度300mg/dlによってグルカゴン分泌が完全に抑制されるようにみえるが, この条件下でもアルギニンがグルカゴンを分泌させることである. このことから次の三つの可能性が考えられる. (1) グルコースはグルカゴン分泌を抑制するがグルカゴン合成にグルコースは必要ではないか,(2) グルコースによって分泌されるインスリンがα 細胞に影響していないだろうか,(3) アルギニンの膜透過にグルコースが必要なのではないかと云うことである.

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.

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, HDL<sub>2</sub> and HDL<sub>3</sub> 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 HDL<sub>2</sub>-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.

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 (HbA<sub>1</sub>) 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.

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.

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.

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 patient is a 14 year old boy, who admitted to our Department because of severe hemorrhagic diathesis and oliguria following a bite by Rhabdophis tigrinus. He had a snake bite on the 5th finger of right hand on September, 28, 1980. After 9 hrs, he noticed the bleeding at the sites of snake bite and gingiva. On the next day, he developed nasal, gastrointestinal, petechial and subcutaneous bleeding and hematoma 2 days later, and macroscopic hematuria 3 days later.Hemostatic examinations revealed complete incoagulability of whole blood clotting time, partial thromboplastin time, prothrombin time, serial thrombin time, and decreased amount of fibrinogen and elevated level of FDP. However, platelet count increased up to 50×104/mm3 at about 30 hrs after the snake bite. About 34 hrs after the first examination, platelet count decreased to 2.3×104/mm3, and at this time a diagnosis of disseminated intravascular coagulation (DIC) syndrome was made. As antiserum against this snake venom was not available, exchange blood transfusion was performed. His clinical feature and the hemostatic function were recovered well on the following days, while chronic renal failure has been persisted for several months.From above results, the exchange blood transfusion is favorable therapy in order to exclude the snake venom from the blood circulation.
