Seventeen serum markers (including 9 enzyme activities) for eventual tissue damage were studied after ESWL in 40 patients with unilateral kidney calculosis. No changes were established in the 8 non-enzymic parameters and the activities of amylase, lipase, AST (GOT), ALT (GPT) and CK-MB. A statistically significant increase was found in LDH, alpha-HBDH, CK (twice) and glutamate dehydrogenase (3 times). The slight elevation of LDH and alpha-HBDH could be due to haemolysis caused by the shock waves. Increased activity of CK suggested myolysis and that of GlDH a hepatocellular damage.

We used cross circulation as an assist method for orthotopic heart transplantation in eight dogs. Seven of the eight dogs could be extubated on the first to third postoperative day and were able to eat and walk several hours after extubation. The survival times and the causes of death in these eight dogs were as follows: 436 days (alive), 5 days (sudden death), 17 days (rejection), 17 days (pyothorax), 3 days (accidental death), 59 days (rejection), 19 days (pneumothorax), and 188 days (alive). None of the dogs died of any problems related to the use of cross circulation. Hematologic and biochemical studies revealed that the CK, CK-MB, LDH, GOT, GPT, and lactate levels increased shortly after the operation and returned to the preoperative values within 14 days. The blood urea nitrogen, creatinine, amylase, hematocrit, and total protein levels remained almost unchanged. No free hemoglobin was detected. These findings indicated that no severe damage occurred to the recipient's organs. The key factors for performing successful cross circulation are as follows: (1) The body weight of the support dog should be at least three times that of the recipient. (2) The systolic pressure of the support dog and the pressure gradient between the support and the recipient should be kept above 150 mm Hg and 50 mm Hg, respectively. (3) The flow rate in the arterial tube should be maintained at between 30% and 50% of the basal cardiac output of the recipient. In conclusion, cross circulation is a suitable assist method for orthotopic heart transplantation in the dog.

One hundred and three patients presenting to the Mt. Sinai Medical Center emergency department (ED), who appeared on clinical grounds to be acutely intoxicated, were studied to determine the rate of clearance of ethanol from blood. The mean presenting serum ethanol level was 299 mg/dL. The rate of clearance was found to be 20.43 mg/dL/h with a standard deviation of 6.86 mg/dL/h. No correlation was found between rate of ethanol clearance and serum levels of amylase, alkaline phosphatase, glutamate-oxaloacetate or glutamate-pyruvate transaminase, lactic dehydrogenase, or total bilirubin. Similarly, no correlation was found between rate of clearance and race, sex, age, or time of day. We conclude that although the average patient presenting to the emergency department will clear ethanol at about 20 mg/dL/h, a standard deviation of 6 mg/dL/h means that only 83% of these patients will have clearance rates between 8 and 32 mg/dL/h, and that if accurate estimates are necessary, serial determinations of two or more levels are needed.

The effects of soman poisoning on hematological (counts of red blood cells (RBC), white blood cells (WBC), and platelets and measurement of hematocrit) and coagulation parameters (prothrombin time, activated partial thromboplastin time, thrombin time and concentrations of fibrinogen, factor V, factor VII, and factor XI) and serum biochemistry (concentration of albumin, protein, calcium, cholesterol, triglycerides, blood urea nitrogen (BUN), magnesium, and creatinine and activities of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, cholinesterase, creatinine phosphokinase (CPK), hydroxybutyrate dehydrogenase, and amylase) were determined at 1, 2, 4, 24, and 48 hours after poisoning of rabbits. There were significant (p less than 0.05) decreases in the RBC counts in all treatment groups that were measured initially at 4 hours and were reflected by parallel decreases in the hematocrit values. These changes were probably due to an increase in the hemolysis of the RBC rather than a decrease in the production of RBC. There were minor changes in the coagulation parameters. Generally, the fibrinogen content increased. The activated partial thromboplastin time decreased significantly (p less than 0.05) 24 and 48 hours after soman (50 micrograms/kg) poisoning. Blood cholinesterase values were significantly reduced in all treatment groups at all time periods. The CPK activity was increased after 4 and 24 hours in the 20 and 50 micrograms/kg soman groups. There were minor changes in the other biochemistry values, but none that showed a dose-response relationship; thus, they were considered to be of limited significance with regard to the toxic manifestations of soman exposure.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors reported on a three month long EPREX (human recombinant erythropoietin) therapy of 5 hemodialysis patients for the treatment of their anemia. The drug was administered in bolus form 2 or 3 times a week after dialysis in a dose of 50 to 150 IU/bodyweight increased gradually in every (or every second) week. Hgb ad Htk values were determined once a week while erythrocyte, leukocyte, thrombocyte and reticulocyte count once a month. Serum iron, TIBC, serum ferritin, BUN, serum creatinine, urea, serum ions, liver function assays, serum lipids and amylase were also established. Hgb, Htk levels and reticulocyte count have significantly increased in the 4th week of treatment already, severe anemia ceased with improved appetite, general condition and physical strength. Serum urea and LDH levels significantly increased while SGOT decreased. No significant change in leukocyte and thrombocyte count, serum Na, K, Ca, P, Cl, BUN, creatinine, total protein level, serum albumin, bilirubin, alkaline phosphatase, GGT, GPT, amylase and blood sugar as well as serum lipid level were observed. No adverse reactions occurred during the treatment. After the three gradually decreased and within 6 weeks they had to be transfused again. In three patients the need for transfusion has significantly grown after the treatment. The authors consider EPREX a highly efficient drug in the treatment of anemia in dialysis patients.

A retrospective study has been carried out, comparing 87 patients with acute pancreatitis of biliary etiology and 53 patients with pancreatitis secondary to other causes. The clinical presentation, laboratory data, radiological findings (chest X-rays, radiography of the abdomen and gastrointestinal, echography), morbidity and mortality have been analyzed. In acute pancreatitis related to biliary disease, pain is most frequently located in the right hypochondrium and the levels of amylase, GOT, GPT an alkaline phosphatase were higher, although only the last two parameters showed significant differences. Morbidity (local and general complications) did not show differences in both groups, but mortality was higher in pancreatitis secondary to biliary disease (5.6% compared to 3.7%).

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.

Aspartate transaminase, alanine transaminase, alkaline phosphatase and amylase levels were significantly increased in experimental female Swiss albino mice infected with single doses of 500, 1,000 and 2,000 larvae of Ancylostoma caninum. Increase of enzyme levels is due to the leakage of large amounts of enzymes into the blood. The necrosis of cells during intestinal and extra intestinal phases of ancylostomiasis in mice is directly responsible for the increase of enzymes.

The toxicity of L-canavanine was investigated because of its demonstrated potential as an antitumor drug. This natural product was only slightly toxic to Sprague-Dawley rats following a single sc injection: the LD50 was 5.9 +/- 1 8 g/kg in adult rats and 5.0 +/- 1.0 g/kg in 10-day-old rats. Following a single dose of 2.0 g/kg, the systemic clearance value for canavanine in adult rats was 0.114 liter/hr, the volume of distribution at steady state was 0.154 liter, and the half-life was 1.56 hr. Forty-eight percent of the dose was excreted unaltered in the urine following an iv injection, and 16% of a sc dose was recovered in the urine. Bioavailability of a 2.0 g/kg sc dose was 72%. Single oral doses of canavanine were less toxic to adult rats than sc injections. Bioavailability of a 2.0 g/kg po dose was 43%, and only 1% of the administered canavanine was recovered in the urine. Twenty-one percent of the administered canavanine remained in the gastrointestinal tract 24 hr after an oral dose. Less than 1% of a 2.0 g/kg dose of L-[guanidinooxy-14C]canavanine was incorporated into the proteins of adult and neonatal rats 4 or 24 hr following administration. Repeated sc administration of canavanine resulted in more severe toxicity. Weight loss and alopecia were observed in rats given daily sc canavanine injections for 7 days. Food intake was decreased by 80% in adult rats subjected to this dosing regimen, but returned to normal after canavanine injections were terminated. Histological studies of tissues from adult rats treated with 3.0 g/kg canavanine daily for 6 days revealed pancreatic acinar cell atrophy and fibrosis. Serum amylase and lipase levels were elevated following one sc injection of 2.0 g/kg canavanine; after three daily injections both serum enzymes were depleted. Elevations in serum glucose and urea nitrogen, and depletion of cholesterol, were observed. The most significant changes were severe attenuations of serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase activity.

Three clinicobiochemical systems have been proposed for predicting gallstones in acute pancreatitis based on one, three and five factors respectively, but have not been compared in a single prospective study. System 1 is based on the serum transaminase alone; system 2 uses alkaline phosphatase and bilirubin in addition to transaminase; and system 3 involves female gender, age, amylase and alkaline phosphatase in addition to transaminase. Over the 4-year period 1983-86, 368 patients with 391 episodes of acute pancreatitis had clinicobiochemical analysis within 48 h. Of these episodes, 220 were related to gallstones (56 per cent), 62 to alcohol (16 per cent) and 109 to other aetiologies or were idiopathic (28 per cent). Significant differences were found between the biliary and non-biliary groups with respect to sex (139 versus 59 women, P less than 0.002), age (65 +/- 17 versus 52 +/- 19 years, P less than 0.0001) and serum amylase (6041 +/- 6335 versus 4546 +/- 3990 units/l, P less than 0.0001), alkaline phosphatase (257 +/- 225 versus 141 +/- 137 units/l, P less than 0.0001), alanine transaminase (221 +/- 227 versus 72 +/- 119 units/l, P less than 0.0001) and bilirubin (40 +/- 39 versus 24 +/- 30 mumol/l, P = 0.0001). The sensitivity and specificity was 75 per cent and 74 per cent for the one-factor system, 74 per cent and 78 per cent for the three-factor system and 62 per cent and 80 per cent for the five-factor system. The predictive value of a positive result was 78.8 per cent, 81.5 per cent and 80.1 per cent and of a negative result 69.4 per cent, 70.1 per cent and 62.3 per cent for the three systems respectively. The performances of the one- and three-factor systems were marginally better than that of the five-factor system; the one-factor system, however, had the advantage of simplicity.
