In the majority of patients with intestinal infarction, it is generally agreed that the occlusion of mesenteric arteries or vein is the primary etiologic factor; however, some showed no evidence of thrombosis, embolization or vasculitis as the causative factor. In many patients, this particular type of infarction is the terminal event of the episode. From October 1977 to December 1986, 24 patients with mesenteric infarction were investigated following cardiovascular surgery in our institute. Among them, 15 were diagnosed with organic vascular occlusion; however, the other 9 showed no evidence of thromboembolism or any other organic vascular occlusive lesion of mesenteric vessels and were diagnosed as non-occlusive mesenteric infarctions. All of these patients were in severe cardiac failure (LOS) postoperatively. There was no typical symptom, although abdominal fullness and diarrhea were the major and consistent findings. In blood chemical analysis, the enzymatic levels such as serum GOT, LDH and CPK were significantly elevated and discrepancy between serum GOT and serum GPT was observed. In this clinical situation, it was difficult to establish a correct diagnosis mainly because of the few signs and symptoms present relating to the mesenteric infarction. On the other hand, when the correct diagnosis was made, these patients were too critically ill to be treated conservatively. The outcome of these patients was grave and all of them died which showed 100% of mortality rate. The conservative management did not produce favorable progress, which accelerated LOS and prevented patients from recovering from cardiac failure. The aggressive surgical approach to this particular type of acute mesenteric ischemia might have offered an improved prognosis from these catastrophic events.

A 77-year-old woman with a 9 years history of Parkinson's disease was admitted to our hospital because of high fever, disturbance of consciousness, increased muscular rigidity and abnormal involuntary movements. She was continuously treated with levodopa + carbidopa (Menesit) 300 mg and amantadine 150 mg every day until admission. On admission, the pulse rate was 102 per minute, blood pressure 90/40 mmHg, body temperature 40.9 degrees C, and bloody stool was noticed. On laboratory examination, erythrocyte sedimentation rate was 6 mm/h, thrombocytes 8.1 X 10(4)/microliters, fibrinogen 91 mg/dl, FDP 40 mg/ml, suggesting DIC. According to her biochemical examination, serum GOT (167 u), GPT (119 u), CPK (847 IU/l), BUN (53.9 mg/dl) and myoglobin (10,370 ng/ml) were increased. These laboratory data indicated that she was suffering from neuroleptic malignant syndrome (NMS) with disseminated intravascular coagulation (DIC). On diagnosis of NMS associated with DIC, she was treated with dantrolene and FUT-175. Dantrolene was effective on the elevated COK level and FUT-175 was effective on the DIC, and symptoms of NMS and DIC were completely improved after a period of 14 days. Patients with Parkinson's disease have been suspected to have a low incidence of DIC, and this may be the first case report on successful treatment of levodopa-induced NMS with DIC in the patient with Parkinson's disease.

141 children, aged 1 month to 3 years, admitted to an intensive care unit in a critical condition caused by severe acute intestinal infections revealed high levels of GOT, GPT, alkaline phosphatase, LDG, and CPK activity, the degree of increment and the form of combinations depending on the type of the condition. On the basis of enzymological investigations a diagnostic table has been compiled characterizing 6 forms of critical conditions most frequently observed in children with acute intestinal infections. This facilitates early diagnosis of critical conditions and makes it possible to perform timely and adequate intensive therapy.

An autopsy case of rhabdomyolysis following homicidal intoxication of paraphenylenediamine was reported and the toxicological mechanism of PPD against skeletal muscles was discussed. The case was a 44 years old, previously healthy male, drinking a beverage containing PPD, prepared for a homicidal use. Total intake of PPD was about 3 g (63 mg/kg). Principal clinical manifestation of the patient was muscle rigor with tenderness, initially developed in the lower extremities and subsequently extending to all over the skeletal muscles. Laboratory examinations disclosed high CPK (137,600), LDH (3895), GOT (3400) and GPT (545), and leukocytosis (26600), indicating massive skeletal muscle necrosis. ECG revealed mild depression of ST junction in the II and aVF leads. Urine showed dark brownish discoloration and diminished in volume subsequently. Scattered necrosis of muscular fibers was observed in a biopsy of the femoral muscles. The consciousness was rather clear during the course. The patient collapsed suddenly and soon died in the course of about 30 hours. Clinically, the cause of death was thought to be acute renal failure due to rhabdomyolysis. Afterwards PPD was detected in the urine obtained in the hospital. Autopsy confirmed the clinical diagnosis: Renal collecting ductules and distal tubules were occluded by dark brownish myoglobin casts and its epithelium massively necrotized; Skeletal muscles showed scatteredly coagulation necrosis and were partially associated with inflammatory cell infiltration.

In the paper are presented the results of total enzyme activity investigation: GOT, GPT, LDH and CPK, and of the CPK isoenzymes in the cerebrospinal fluid of 148 examinees and in the serum of 67 examinees with an acute stroke, who were treated at the Intensive Care Unit of the Department of Neurology and Institute of Neuropathology, Clinical Medical center "Rebro". The aim was to determine the reliability of the applied methods in the diagnosis of cerebrovascular diseases, particularly in the differential diagnosis of cerebral hemorrhage, ischemia and subarachnoidal hemorrhage. The highest frequency of pathologic findings of the tested enzymes in the whole group of patients with CVA was obtained in the determination of the CPK total activity assessment, then followed the assessments of LDH activity, isoenzyme CPK profile, GOT and finally GPT activity. A larger number of pathologic findings of all mentioned enzymes and CPK isoenzymes was found in the group of patients with ICH. In the patients with ICH and ISI, who survived stroke a higher incidence of normal findings of the total enzymic activities was found, while in those who died from ICH a higher incidence of pathologic findings could not be established. The correlations between the total CPK activity in the serum and in the cerebrospinal fluid does not exist, as well as the correlation between the CPK isoenzyme profile in the serum and CSF.

The feasibility of maintaining long-term viability of human venous allografts by cryopreservation has been investigated. Segments of vein were obtained from 85 patients undergoing a stripping operation for varicose veins. The venous segments were immersed in a dimethylsulfoxide 15% solution, deep frozen at -196 degrees C in liquid nitrogen and preserved for a duration of 1 week to 24 months. Light microscopy (n = 126) failed to demonstrate striking differences between control veins and any of the cryopreserved veins. The types of damage observed at scanning electron microscopy included endothelial cell separation, endothelial cell loss, exposed basement membrane and exposed fibrillar collagen, which were graded on a scale. The score for short term (less than 3 weeks) stored veins was 8.1 +/- 0.9 (mean +/- SEM) and did not differ from the long-term (greater than 10 weeks) stored veins score (6.3 +/- 1.0, p NS). The tissue enzymes LDH, GOT, GPT, CPK were measured in the frozen vein groups (n = 115) after thawing to room temperature. Cryopreservation did not alter any of the tissue enzymes measured when compared to controls. Endothelial fibrinolytic activity (FA) of 58 venous segments cryopreserved for a mean duration of 20 months was 6136.4 +/- 292.1 Tissue Activator Units (TAU) and did not differ from FA of 11 controls (5989.1 +/- 696.8 TAU). Synthesis of 6-Keto-PGF1-alpha-2, a stable breakdown product of PGI2, measured in 10 venous segments cryopreserved for 10 months, was significantly higher than in 13 veins stored in saline for 12 hours at 4 degrees C (2.8 +/- 0.4 vs 0.4 +/- 0.1 PG ml-1mg-1min-1, respectively; p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

A herbal tea (called an abafado in Brazil) prepared from the dried leaves of lemongrass was administered to healthy volunteers. Following a single dose or 2 weeks of daily oral administration, the abafado produced no changes in serum glucose, urea, creatinine, cholesterol, triglycerides, lipids, total bilirubin, indirect bilirubin, GOT, GPT, alkaline phosphatase, total protein, albumin, LDH and CPK. Urine analysis (proteins, glucose, ketones, bilirubins, occult blood and urobilinogen) as well as EEG and EKG showed no abnormalities. There were slight elevations of direct bilirubin and of amylase in some of the volunteers, but without any clinical manifestation. These results taken together indicate that lemongrass as used in Brazilian folk medicine is not toxic for humans. The eventual hypnotic effect of lemongrass was investigated in 50 volunteers who ingested samples of lemongrass and a placebo under double-blind conditions. The parameters (i.e. sleep induction, sleep quality, dream recall and rewakening) did not show any effect of lemongrass as compared to the placebo. Eighteen subjects with high scores of trait-anxiety were submitted to an anxiety-inducing test following taking lemongrass or placebo under double-blind conditions. Their anxiety levels were similar, indicating that the abafado of the plant does not have anxiolytic properties. It is concluded that lemongrass, one of the most popular Brazilian herbal medicines, used for its alleged CNS-depressant effects, is atoxic but lacks hypnotic or anxiolytic properties.

After the evaluation of 129 serum samples of persons who had ingested boar sausage infested by Trichinella spiralis, 48 individuals (40 adults and 8 children) with a mean age of 38.8 years were diagnosed of trichinosis. The incubation time was 17 days (range 2 to 44 days). The following clinical features were outstanding: facial and eyelid edema (50%), diffuse limb myalgia (43%), fever (37%), conjunctivitis (25%), headache (16%), and abdominal pain (16%). Remarkably, 33% of the diagnosed patients were asymptomatic. The diagnosis was made by an indirect immunofluorescence technique (IIF), which was considered as positive when the titer was higher than 1/20 after considering seroconversion at the beginning of the disease and after 4-6 weeks. Among laboratory abnormalities there was leukocytosis in 15 patients and eosinophilia in 37. The GOT, GPT and CPK enzymes were only slightly increased in a small proportion of patients (8, 10, and 31%, respectively). Forty patients were treated with thiabendazole, associated or not to corticosteroids, which was well tolerated. Eight patients were not treated. One year after the diagnosis a new laboratory control was undertaken in 43 patients (all asymptomatic). Eosinophilia was still present in 12, and the titers against Trichinella were high in all. However, the percentage of the titer was smaller than at the beginning of the outbreak.

The primary cause of death following i.v. injection of the basic phospholipase A2 (PLA2) from Naja nigricollis venom has been attributed to its direct cardiotoxicity. In view of our recent findings that cardiac failure caused by the basic PLA2 from Naja m. mossambica is primarily due to hyperkalemia resulting from cellular damage and possibly also from hemolysis, the cause of death due to the basic PLA2 from Naja nigricollis was re-investigated. In the anesthetized mice and rats, the PLA2 (0.3 micrograms/g, i.v.) produced a transient hypotension followed by recovery and subsequently by cardiac failure with ECG changes suggestive of hyperkalemia, such as P-R prolongation, tall T-wave, biphasic QRS-T complex, low voltage of QRS, A-V block, etc. Analysis of blood chemistry revealed marked increases in the plasma levels of K+, CPK, LDH, GOT, GPT, inorganic phosphate and hemoglobin (probably a mixture of hemoglobin and myoglobin). In the atrial preparation, however, no marked cardiotoxicity was observed except for a slight negative inotropic effect at 30 micrograms/ml. When 200 micrograms of the enzyme was injected into the coronary circulation in the Langendorff preparation, also no marked cardiotoxic effect was observed except for a decrease (about 40%) of coronary flow. From these results, it is concluded that the primary cause of death following i.v. injection of the basic PLA2 from Naja nigricollis is apparently cardiac failure due to hyperkalemia, resulting from cellular damage and possibly also from hemolysis, rather than direct cardiotoxicity.

Three paroxysmal episodes of ST-segment elevation in lead II of ECG were observed during bullectomy and chest closing under epidural anesthesia supplemented with enflurane in compressed air in a patient who had history of variant angina with 50% obstruction of right coronary artery. The first and the third episodes were followed by ventricular tachycardia, complete A-V block and hypotension. These attacks were preceded by decreases in heart rate and blood pressure. It was suspected that coronary artery spasm developed with increased vagal tone under thoracic epidural block. The first and the second attacks were successfully treated with intravenous injection of nitroglycerin and lidocaine. The third attack needed additional treatments which included intravenous administrations of atropine, epinephrine, isoproterenol and phenylephrine and direct heart massage through the thoracic incision. Postoperative serial examinations of ECG showed inverted T in lead V1-V4, and serum enzymes (GOT, GPT, LDH, CPK, CPK-MB) were elevated. However ratio of CPK-MB to total CPK was only 1.5%. The patient was discharged two weeks after the operation with normal ECG and serum enzymes. It is speculated that coronary artery spasm was induced by hypotension and vagal stimulation under epidural anesthesia which blocks cardiac sympathetic nerves.
