脳出血, 脳梗塞に伴う心電図変化の成因を検討する目的で, 発作前1カ月内及び発作後の心電図, 臨床検査成績が得られ, 剖検上確認された老年者脳出血18例, 脳梗塞29例について, 発作前後の心電図, 臨床検査成績, 血圧の変化, 剖検による冠狭窄度, 脳病変の部位, 大きさ等を対比検討した.発作前後の心電図変化は脳出血88.9%, 脳梗塞89.7%に認められST, T変化がそれぞれ61.1%, 69.0%と高頻度に見られ, 高度な虚血性変化は脳梗塞で多く見られた. 不整脈は脳出血55.6%, 脳梗塞41.4%に見られ, 発作時の心房細動出現は脳梗塞にのみ10.3%に見られた. 期外収縮は脳出血に多く上室性22.1%, 心室性11.1%, 脳梗塞ではそれぞれ10.3%, 3.4%であった.脳卒中発作前後のヘマトクリット上昇は脳梗塞で大きい傾向があり, 虚血性ST, T変化を示した群では脳出血2.44±0.57, 脳梗塞6.04±1.74の上昇を示し, 著明なヘマトクリットの上昇による冠微小循環の障害が虚血性ST, T変化を斉すことを示唆した.脳卒中発作時の収縮期血圧上昇は脳出血では52.5±8.9mmHgで心電図変化の程度に拘らず200mmHg以上の高値を示したが脳梗塞では8.7±10.4とその変動は僅かで血圧上昇が心電図変化の原因とはいえなかった.冠動脈狭窄の程度は脳出血, 脳梗塞共各心電図変化群の間に狭窄指数の差が見られず, 虚血性心電図変化が太い冠動脈の狭窄によるものではないことを示した. 一方心筋梗塞の合併は脳出血5.6%に比し脳梗塞で50.0%と有意に高頻度であった.脳病変の部位, 大きさでは外側型脳出血に虚血性ST, T変化の多い傾向が見られたが, 脳梗塞では中大脳動脈領域の梗塞に於ても心電図変化に一定の傾向はなく, 部位による特徴は認められなかった. また両群共病巣の大きさと心電図変化には一定の傾向は見られなかった.脳出血, 脳梗塞の虚血性心電図変化は病巣の部位, 大きさ, 冠硬化, 血圧上昇等とは関連が認められず, ヘマトクリット上昇による冠微小循環の障害がその一因と考えられた.

Effects of γ-oryzanol on the serum HDL, LDL and total cholesterol (ch) and Triglyceride were studied in 17 cases whose age was 47 years old to 82 years old (mean age was 71.2 years old). Three hundred mg/day of γ-oryzanol was given for 4 months.Serum HDL-ch was 50.0±2.3 (m±SE) mg/dl before γ-oryzanol and 53.7mg/dl 3 months later but HDL-ch which was below 50mg/dl before treatment increased significantly (p<0.01) from 43.3mg/dl to 50.4mg/dl 2 months later. HDL-ch below 45mg/dl increased significantly (p<0.01) from 41.3mg/dl (mean) to 50.0mg/dl (mean) 2 months later. LDL-ch decreased significantly (p<0.01) from 158.8mg/dl to 134.8mg/dl after γ-oryzanol. HDL-ch×10/LDL-ch showed significant changes (p<0.01) (from 3.26 to 4.14) 2 months later. Total-ch did not change and between 203mg/dl and 208mg/dl. Triglyceride did not show significant changes.It is suggested that γ-oryzanol alters the metabolism of HDL-ch and LDL-ch and increases serum low HDL-ch.

Recently, growing interests had been devoted largely to disseminated intravascular coagulation (DIC), because of its frequency and clinical importance. It has been known that shock is a frequent complication of DIC, although it has not been elucidated whether shock is a cause of DIC rather than a result. This study was made to clarify relationship between DIC and shock in 699 consecutive autopsied cases, almost all of whom was over age sixty, in Tokyo Metropolitan Geriatric Hospital.<br>The diagnosis of DIC was established when coagulation analysis revealed presence of consumption coagulopathy. Among these cases, 106 had evidences of DIC and 30 had clinical and pathological findings highly suggestive of DIC although the coagulation findings were not specific. Shock was complicated in 38 of the former and 10 of the latter.<br>Eight of these 48 patients with DIC complicated with shock revealed consumption coagulopathy simultaneously with the development of shock. 24 cases had not clea r-cut evidences of DIC immediately after the development of shock in coagulation findings, although they showed marked coagulation abnormalities indicating DIC after the shock developed. 44% of conditions associated with the shock in these patients was gram-negative septicaemia. The other underlying pathologic conditons in these cases consisted of cancer, peptic ulcer, acute myocardial infarction and pneumonia.<br>Onset of shock was observed in 16 cases in whom diagnosis of DIC had been already established by coagulation analysis. 11 cases of these had cancer with metastases, primary organs of which were stomach, colon or biliary tracts. 70% of these patients were febrile.<br>Acute renal failure, purpura, petechiae, melena, coma, epileptic seizure, systemic peripheral gangrene and/or red cell fragmentation in peripheral blood smear were main symptoms in DIC with shock. Four cases, excluding two cases in whom DIC developed following development of acute myocardial infarction, showed ECG findings indicating development of acute myocardial infartion, although myocardial infarction was evident in only one cases by postmortem examination.<br>Presence of fibrin thrombi was confirmed in 36 cases out of the 48 autopsied cases with DIC accompained with shock. Terminal hemorrhagic necrotizing enteropathy was observed in 15 of those cases. Hemorrhage from adrenal was observed in 4 cases.<br>From these results, it is concluded that shock does frequently cause DIC and that shock in gram-negative septicaemia is especially important because of its high incidence to result DIC.

Studies on platelet functions of 21 patients with renal insufficiency have been preformed. Platelet counts were significantly decreased in uremic patients, although severe thrombocytopenia less than 100&times;10³ platelets/mm³ was detected only in two patients. Platelet adhesiveness to glass was remarkably decreased in uremic patients. Platelet factor-3 availability was impaired in some of these patients, while platelet factor-3 activity was not decreased. Clot retraction was slightly defective in few patients. The significant correlation was not found between platelet adhesiveness and BUN, creatinine, uric acid or inorganic phosphate level in the serum of these patients. The abnormalities of platelet functions were partially corrected after dialysis.<br>In vitro, urea at high concentration showed an inhibitory effect on platelet aggregation. Guanidinosuccinic acid had less inhibitory effect on platelet aggregation, and creatinine had no inhibitory effect.

A 25-year-old male was admitted because of dark-red urine, jaundice and purpura. 5 days prior to admission, the patient noticed that the urine color became dark red, and purpuric rash and jaundice were noted by his wife.<br>Examination revealed scleral icterus, pallor, numerous petechiae and an ecchymosis. The sensorium was clear. The neurologic examination was normal.<br>The patient had hemolytic anemia, thrombocytopenic purpura, fever and proteinuria. Shortly after admission, fluctuating neurologic symptoms developed, and the patient was diagnosed as thrombotic thrombocytopenic purpura.<br>He was treated with prednisolone and heparin without benefits, and expired on the 14 th hospital day.<br>Hyaline thromboses of the vessels of liver and kidney were demonstrated by the examination of the specimens obtained by post mortem needle puncture.<br>Coagulation studies disclosed that partial thromboplastin time and prothrombin time were slightly prolonged, however, factor V activity and fibrinogen titre were not low. Fibrinogen degradation products determined by tanned red cell hemagglutination inhibition immunoassay were markedly increased, although euglobulin lysis time was not shortened.<br>Immunological analysis of serum proteins showed the increase of acute phase reactants, the decrease of &beta;₁-AC and haptoglobin, and the appearance of fibrinogen degradation products.<br>These results were discussed in relation to the pathogenesis of the disease.

Apparent blood viscosity was measured on freshly shed blood from 127 healthy subjects, ages 21 to 88, and patients hospitalized in Tokyo Metropolitan Yoikuin Geriatrics Hospital, over age 60. Determination of blood viscosity was performed at 37&deg;C using rotational viscometer at shear rates between 0.07 and 4.6sec^-1.<br>Mean blood viscosity in 43 healthy older subjects over age 60 (mean age: 74&plusmn;6) was 45&plusmn;25cp at 0.07sec^-1 and 8&plusmn;2cp at 4.6sec^-1, respectively. Yield stress was calculated from Casson plot at very low shear rates (between 0.44 and 0.07sec^-1) by the method of least squares. Mean value of yield stress in the healthy older subjects was 0.011 dynes/cm². Blood viscosity in the healthy subjects was significantly correlated with hematocrit values. Yield stress in these subjects was also correlated with hematocrit values and blood viscosity at very low shear rates. In these healthy subjects, blood viscosity, yield stress and hematocrit values were highest in the group at age 30-39. Blood viscosity and yield stress showed a slight decline with age in the healthy older subjects.<br>In the hospitalized patients, blood viscosity was higher than 70cp at 0.07sec^-1, and/or higher than 11cp at 4.6sec^-1 in 107 measurements (86 cases) out of 1443 determinations from December 1973 to October 1974. These patients with blood high viscosity included 12 cases of cancer (one of them was accompanied with disseminated intravascular coagulation (DIC); three of them developed DIC thereafter), 5 cases of acute myocardial infarction, 4 cases of acute cerebral infarction, 5 cases of angina pectoris, 6 cases of old myocardial infarction, 18 cases of old cerebrovascular diseases, 11 cases of diabetes mellitus, and 5 cases of stress polycythemia or polycythemia vera. In these cases, viscosity at 4.6sec^-1 was significantly correlated with hematocrit values, whereas viscosity at 0.07sec^-1 was not. All patients with blood high viscosity and relatively low hematocrit values suffered from cancer. In 6 cases of acute myocardial, cerebral of renal infarction, in whom changes in blood viscosity, yield stress and hematocrits were investigated before and after the development of infarction, changes in blood viscosity and yield stress were parallel with hematocrits.<br>From these results, it was concluded that high hematocrits caused blood high viscosity and were regarded as one of the risk factors in the pathogenesis of thrombosis, although the other factors than hematocrits might also influence blood viscosity at very low shear rates.

Coagulability of blood was measured in 80 cases of acute myocardial infarction, 98 cases of acute cerebral infarction and 33 cases of acute cerebral hemorrhage. Platelet counts, activated partial thromboplastin times, prothrombin times, plasma fibrinogen content, levels of plasma antithrombin III, α₂-macroglobulin and fibrin degradation products (FDP) determined within 1 month before the attack of myocardial infarction or stroke, and those measured within 48 hours or 3 to 7 days following the onset of these diseases were compared with data obtained from 370 healthy subjects over age sixty.<br>Concentrations of plasma antithrombin III were apparently decreased before and after the development of myocardial infarction. In ten autopsied patients with acute myocardial infarction, three cases with extremely low levels of plasma antithrombin III (less than 2 mg/d<i>l</i>) were complicated with disseminated intravascular coagulation (DIC), acute cerebral infarction and/or thromboembolism of lower extremities, while no thromboembolic episodes following myocardial infarction were observed in the other seven cases in whom plasma antithrombin III concentrations were more than 20mg/d<i>l</i>. Levels of the other thrombin inhibitor in plasma than antithrombin III, i. e. α₂-macroglobulin, were increased immediately after the occurrence of cerebral hemorrhage. Plasma fibrinogen content was markedly increased after the development of myocardial infarction or cerebrovascular diseases. Activated partial thromboplastin times, prothrombin times and FDP did not significantly change before and after the development of these diseases. These data suggest that there may be a relation between development of myocardial infarction and the low levels of plasma antithrombin III. Increased levels of plasma fibrinogen, as a result of myocardial infarction or stroke, may not accelerate coagulation mechanism but act disadvantageously by elevating blood viscosity.<br>Relationship between activated partial thromboplastin times, prothrombin times, plasma fibrinogen content, levels of plasma antithrombin III, α₂-niacroglobulin or FDP, determined within 1 month before death, and grade of atherosclerosis of aorta, cerebral, coronary or femoral artery, classified grossly with the naked eye, was investigated in 186 autopsied cases without cancer or DIC, retrospectively. There were no correlations between these parameters and the grade of atherosclerosis, except that levels of FDP were significantly increased in cases with severe atherosclerosis of femoral artery. From these results, direct evidences supporting thrombogenic hypothesis of atherosclerosis suggested by Duguid were not obtained. However, atherosclerotic lesion of peripheral artery may activate clotting processes and increase FDP.

脳卒中発症前後のヘマトクリット (Hct) 値, ヘモグロビン (Hb) 値, 赤血球 (RBC) 数, 血清総蛋白 (TP) 値の変動について検討し, これらの値の変動と脳硬塞および頭蓋内出血発症との関係について考察することを目的に本研究を行なった.<br>対象は60歳以上の脳卒中例のうち, 急死あるいはこの研究の為の検査が不充分な症例を除外し, かつ剖検によって病変を確認しえた脳硬塞21例, 頭蓋内出血16例, 計37例である. Hct, Hb, RBC, TP値の測定は自動測定装置によった. 発症前値については発症4日以内 (直前値) と5日以上の値に分けて検討した.<br>結果; 1) 脳硬塞においては, Hct 値は発症前値 (37.2±3.3%) に比し, 発症日の値 (38.9±3.0%) は高かった. Hb, RBC, TP値についても同様の結果が得られた. しかし, 頭蓋内出血においては, 発症日における Hct, Hb, RBC, TP値は発症前値に比し, やや高い傾向がみられたが有意の差は認められなかった. 以上の結果より, 急激な Hct 値の上昇と脳硬塞の発症との間に何らかの関係が存在する可能性が推定された. 2) 脳硬塞では頭蓋内出血群に比し, Hct, Hb, RBC値が発症前, 発症日ともに有意の高値であった. しかし, TP値には両者で差が認められなかった. 脳硬塞発症前の Hct 値は同年代の対照群に比し有意の差が認められなかった. 3) 脳硬塞, 頭蓋内出血ともに Hct, Hb, RBC値は, 発症後数日間漸増する傾向がみられた. しかし,TP値は両者とも発症後急速に低下した.

Two families of congenital factor VII deficiency were described.<br>The propositus of the first family was 35-year-old female, who was admitted for anemia. Spontaneous epistaxis, limited to her youth, was main hemorrhagic symptom. The patient delivered two normal children without unusual bleeding. On admission, the physical examination revealed no abnormalities except for the presence of iron deficiency anemia. Results of liver function tests were normal. Coagulation data confirmed the diagnosis of pure factor VII deficiency. Her factor VII complex level was 5% of normal and factor X level was 100%. There was no history of bleeding in her family. However, her daughter was discovered to have factor VII deficiency. Her factor VII complex level was 27% and factor X level was 75%. Factor VII levels of father, three half siblings, husband and son of the propositus were within normal limits.<br>The propositus of the second family was 25-year-old female, who was admitted complaining of spontaneous nose bleeding, gum bleeding, subcutaneous hemorrhage and menorrhagia. The patient was hospitalized for right oophorectomy at the age af 22. The hematoma in the right ovary was found, however, no unusual bleeding was noted either during surgery or in the postoperative period. On admission, she appeared healthy except for a few ecchymoses. Liver function chemistries were normal. Laboratory data demonstrated factor VII deficiency with increased vascular fragility. Her factor VII complex level was 17% and factor X level was 80%. Mixture of this patient's plasma with that of the propositus of the first family did not result in shortening of the long one-stage prothrombin time, proving an identical deficiency in these patients. The family history revealed that the patient's paternal grandfather were siblings. One brother of the propositus, his daughter and grandmother on the father's side of the porpositus had bleeding tendency. Neither of her parents nor any other family members had any bleeding episodes. Coagulation studies on the brother of the propositus revealed that he had factor VII deficiency. His factor VII complex level was 12% and factor X level was 105%. Factor VII level of the other family members could not be measured.
