Seven elderly cases with reversible electrocardiographic changes simulating acute myocardial infarction in the absence of gross myocardial infarction on postmortem examination were observed following the blood transfusion. The underlying diseases were cancer of gastrointestinal tract or gall bladder in 4,
gastric ulcer
in 2, and 1 of pseudomembranous enterocolitis. The electrocardiogram revealed the abnormal Q waves with monophasic ST elevation and following coronary T inversion. These findings lasted only for 2 to 7 days and returned to the previous normal tracings. The hematocrit was elevated from 28.9 to 47.7 after the blood transfusion of 800 to 1,800 ml. The
disseminated intravascular coagulation
was shown in 5 cases. GOT levels were within normal ranges except 1 case. Pathological findings in cases with recent electrocardiographic changes were characterized by the mural thromboses, extending into the myocardium through the Thebesian vein. The focal small necroses of the adjacent myocardium or around the thrombosis of small vessels were also observed. In the later phase the fine interstitial fibrosis took place after the resorption of the thrombi and necrotic foci. From these clinical and pathological findings we proposed a new concept of reversible myocardial infarction induced from the hypercoagulability,
disseminated intravascular coagulation
, and elevated hematocrit.

It is widely accepted that patients with aortic aneurysm (AA) show a higher incidence of peptic ulcers than those without. However, the pathogenesis of peptic ulcers associated with AA remains obscure. We measured the gastric mucosal blood flow (GMBF) endoscopically and also determined the gastric mucosal prostaglandin (PG) levels of these AA patients to investigated the mechanism behind
gastric ulcer
formation. Moreover, we investigated the
consumption coagulopathy
(CC) of AA responsible for inducing the hemorrhage from ulcers. The GMBF values of 7 AA cases, taken at the antrum, angle and corpus, were significantly decreased compared with those of control cases, while the PGE2 levels of the gastric mucosa were also significantly reduced. With regard to CC, the serum levels of fibrinogen or platelets were significantly lower than those of the control group. These results indicate that the decrease in GMBF, followed by the reduction in endogenous PG, might contribute to the
gastric ulcer
formation in AA patients, and that CC associated with AA could be an important factor causing the hemorrhage from these ulcers. AA patients should therefore be treated with focusing attention on the possibility of an associated ulcer and ulcer bleeding.

Various blood flow disturbances in intraabdominal digestive organs were studied clinically and experimentally from a viewpoint of vascular surgery. Acute gastric mucosal lesion may occur due to ischemia and reperfusion injury of the gastric mucosa. Bleeding from
stomach ulcer
may be rarely caused by
consumption coagulopathy
along with aortic aneurysm. Heparin therapy was successful to interrupt it. Gastrectomy is not indicated for such condition but aneurysm should be repaired. Portal vein reconstruction for the radical resection of hepatic, biliary and pancreatic cancers should be carefully made, because early or late stenosis occurs frequently, and they may connect to early or late morbidities or mortalities. On the other hand, resection and replacement of the suprarenal vena cava invaded by the retroperitoneal malignant tumor may be safely carried out. For the acute mesenteric arterial occlusion, early diagnosis and arterial reconstruction are essential to save catastrophe. Positive Doppler sound on the vasa recta seems to be the most reliable parameter for assessing bowel viability. Approach from the proximal large arteries is recommended for uncontrollable intraperitoneal bleeding.

We reported a case of 64 a year-old male patient of miliary tuberculosis associated with ARDS,
DIC
and pneumothorax, who had a history of
gastric ulcer
and pulmonary tuberculosis. On admission his chief complaints were fever, fatigue, palpitation, appetite loss and weight loss, and most noticeable abnormalities were bleeding from the
gastric ulcer
and miliary shadow on the chest x-ray film with hypoxemia. On the day after admission to the hospital he was diagnosed as ARDS as he showed severe hypoxemia due to extensive tuberculous infiltration in bilateral lung fields, and treatment with antituberculous drugs and steroids were started. On the third hospital day
DIC
appeared on laboratory data, Gabexate mesilate (FOY) for
DIC
and respirator for ARDS were introduced. Two weeks later pulmonary infiltration, PaO2 and general condition were somewhat improved. On the 15th day after admission pneumothorax occurred on the right side, and on the 20th day on the left. Tube drainage of both pleural cavities, and instillation of OK-432 and Fibrinogen HT into the right pleural cavity were done, but it showed no effect. Two months after admission pouring Fibrinogen HT and thrombin into the left B1+2 and right B1 with cannula washing pipe through the instrument channel of bronchoscope was carried out. A few days later air leakage stopped and collapsed lungs were completely expanded. This method is effective in the case of incurable pneumothorax with pulmonary hypofunction.

A case of the hemorrhagic
gastric ulcer
and post-operative stomal ulcer associated with the
consumption coagulopathy
in the dissecting aortic aneurysm is presented. A 68 year old man, who had diagnosed as having the dissecting aortic aneurysm (DeBakey III) in 1985 and had been attending to our hospital as an outpatient since then, was admitted to our hospital because of the hemorrhagic
gastric ulcer
on July 3rd, 1987. Although the wide resection of stomach was performed after the admission, the hemorrhagic stomal ulcer was developed 4 weeks after the operation. The administration of heparin in addition to antacids to improve the
consumption coagulopathy
, having been caused by thrombus formation in the aneurysm, was effective in control of the hemorrhage and also making the stomal ulcer scarred. It is suggested that ischemia of the stomach mucosa, which seemed to have been induced by the dissecting aortic aneurysm, was responsible for the development of the ulcers in this case and the hemorrhage from them was caused mainly by the
consumption coagulopathy
derived from thrombus formation in the aneurysm.

We have previously reported that the decrease in gastric mucosal blood flow (GMBF) and
consumption coagulopathy
(CC) mainly contribute to the development of postoperative bleeding in the upper gastrointestinal (GI) tract in patients with abdominal aortic aneurysm (AAA). In the present study, we investigated whether our treatment for patients with low GMBF or CC effectively prevented postoperative gastric bleeding induced by
gastric ulcer
or acute gastric mucosal lesion. Preoperative endoscopic examinations in 66 patients with AAA and 60 patients with arteriosclerosis obliterance (ASO) revealed that 50.0% of AAA and 16.6% of ASO patients had accompanying
gastric ulcer
or multiple erosions. In 38 AAA and 36 ASO patients, GMBF was measured using a laser Doppler flowmeter through an endoscope. The GMBF was severely impaired in AAA patients and moderately impaired in ASO patients. The platelet counts and fibrinogen levels were significantly decreased in these 38 AAA patients compared with controls. Furthermore, fibrinogen degeneration product (FDP) levels in 36.8% of AAA patients were more than 20 micrograms/dl. Based on these findings, patients with low GMBF were treated postoperatively with H2-blocker, and patients with CC were treated preoperatively with heparin. After these treatments, only 1 of 38 AAA patients developed postoperative upper GI tract bleeding and could be treated conservatively after 1988, whereas in prior years postoperative upper GI tract bleeding developed in 7 of 112 patients, three of whom required emergency surgery.

Haematologic disturbances in 13 cases of gastric cancer are described. All the patients had anemia of different origin. Increased leukocytosis was observed in half of the cases, leukemic reaction in one third. Hemolysis was present in 50% of cases. Thrombocytopenia coexisted most frequently with
disseminated intravascular coagulation
in 4 patients. Bone metastases were visualised as osteolytic foci with radiological methods or increased capture of isotopic marker in the bones under scintigraphic examination. Under the microscope neoplastic metastases were found in bone marrow smears of 5 patients. All patients displayed symptoms of
gastric ulcer
disease acute or chronic phase. In some cases only repeated gastroscopic examination and mucosa biopsy was the only way to confirm cancer. In other cases the diagnosis was made after the histopathologic examination of the resected stomach, in still others by a section.

Functional and morphological alterations of microvascular endothelial cells (ECs) would lead to microcirculatory disturbances, thereby providing a basis for the development of a disease state. Clinically endotoxemia frequently encountered in a variety of diseases is considered to be a trigger to develop the microcirculatory disorders such as
disseminated intravascular coagulation
(
DIC
) and multiple organ failure (MOF), both of which feature the end stage of severe systemic disease. Experimentally intravital microscopy reveals that continuous venous infusion of endotoxin (LPS) causes a low flow state in the rat mesenteric microcirculatory unit. By vital stain with monastral blue B (MBB), the microvascular ECs are focally positive for MBB at the postcapillary venular site, where leukocytes adhere and extravasate. As shown in the histamine-induced diapedesis by transmission electron microscopy, the MBB-positve venular ECs may correspond to the contracted ECs, enabling the polymorphonuclear leukocytes and erythrocytes to extravasate through the widened gaps between the contracted ECs. Actin filaments proven in the microvascular ECs by electron microscopy may play a modulating role in this neutrophil diapedesis. In the process of
gastric ulcer
formation under restrained stress to the rat, the ECs of microvessels in the gastric mucosa, particularly of the mucosal capillaries and postcapillary venules directly innervated by the cholinergic nerves, are altered by the stress-induced overstimulation of the autonomic nerves, inducing the diapedesis of leukocytes and erythrocytes followed by hemorrhagic and ischemic injuries in the gastric mucosa. Liver cirrhosis also accompanies endotoxemia. The most prominent electron microscopic alterations of hepatic microvasculature are a decrease of hepatic sinusoidal endothelial fenestrae (SEF) both in diameter and in number, and the formation of basement membranes beneath the hepatic sinusoidal ECs. These ultrastructural changes would be induced by a most potent vasoconstrictor endothelin (ET)-1 through the overexpressed ET(A) and ET(B) receptors on the hepatic stellate cells and the sinusoidal ECs, contributing to the development of portal hypertension as well as to the disturbance in excretion of endotoxin into the bile canaliculi via the hepatocytes from the circulating sinusoidal blood to prevent endotoxemia.

An enzymatic, kinetic method for determining serum lipase activity was evaluated and compared to a standard manual method for use in dogs. The kinetic method was a commercial kit adapted for use on a tandem access clinical chemistry analyzer and utilized a series of coupled enzymatic reactions based on the hydrolysis of 1,2-diglyceride by lipase. The manual method was the Cherry-Crandall technique based on the titration of base against the acid formed by hydrolysis of an olive oil substrate by lipase. The correlation between the two methods was very good (r = 0.94). The reference range for 56 clinically healthy dogs assayed by the kinetic method was 90 to 527 U/L. Diseases associated with a greater than twofold elevation in serum lipase activity as determined by the kinetic method included pancreatitis, gastritis with liver disease, and oliguric renal failure with metabolic acidosis. In some cases, pancreatitis was seen with other clinical problems, such as gastroenteritis, diabetic ketoacidosis, duodenal mass,
disseminated intravascular coagulation
, and septic peritonitis. Diseases associated with serum lipase activity within the reference range or elevated less than twofold included gastritis,
gastric ulcer
, cholestasis, phenobarbital-induced hepatopathy, colitis, copper hepatopathy, abdominal hematoma, apocrine gland adenocarcinoma, and thrombocytopenia with pneumonia.
