Egyptian scorpion venom was collected by electrical stimulation of the telson. Rats were injected with the lyophilized venom in 3 different doses (100, 200 and 400 micrograms/kg). Blood samples were drawn by heart puncture before and 4 h after venom administration. Serum was separated and collected for determination of glucose, blood urea nitrogen (BUN), creatinine, uric acid (UA), total proteins, cholesterol, sodium, potassium, calcium, inorganic phosphorus, alkaline phosphatase, aspartate aminotransferase (AST, GOT), alanine aminotransferase (ALT, GPT), lactate dehydrogenase and creatine phosphokinase (CPK). Serum glucose, creatinine, GOT, GPT and LDH were increased significantly in all treatments. At the same time serum BUN and CPK were elevated significantly with a dose-response relationship. On the other hand, serum total proteins, uric acid, cholesterol, calcium and potassium were significantly decreased 4 h after administration of the 3 doses. These changes in clinical chemistry parameters are most probably related to the toxic effect of the venom on the target organs.

To evaluate the effects of hepatic inflow occlusion without the shunt, the physiological differences were compared in three groups of rats in which the hepatoduodenal ligament was occluded for 15 min, 30 min, and 60 min. The survival rate significantly decreased in the 60 min occlusion group (53.6%) when compared with that of the 15 min and 30 min occlusion groups (95% and 91.6%, respectively). The significant differences in the changes in blood pressure (BP), the values of plasma potassium, histamine (HIS), norepinephrine (NE), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the values of hematocrit (HT) were also observed between the 30 min and 60 min occlusion groups. The results indicate that, in rats, there is a high probability of an irreversible state to shock after 30 min hepatic inflow occlusion when veno-venous bypass is not applied. The values of plasma HIS and NE and the values of HT in portal blood were significantly greater than those in the general circulation. The results suggest that splanchnic congestion may have a greater influence than hepatic ischemia has in contributing to the deterioration of the physiological state.

Laboratory studies are an essential aspect in the management of children with grave diseases, helping to plan the therapeutic measures and to identify the disease. The most acute syndromes in pediatric emergency care are: coma, convulsions, dehydration, metabolic disequilibrium, hypovolemic or anaphylactic shock, a grave infection, chemical or drug poisoning. The laboratory tests that should be available within few minutes are blood cell count, blood and gas analysis, sodium, potassium, calcium, glucose measurements. The results of total proteins, serum creatinine and urea measurements, bleeding tests, analysis of blood smear, sedimentation rate, ALT, AST, osmolality, urinary electrolytes, creatinine and cerebrospinal fluid examinations should be available within sixty min. New accurate and rapid techniques and instruments facilitate the diagnostic and therapeutic approach to pediatric emergency.

A 74-year-old male was admitted to hospital with acute rhabdomyolysis and myoglobinuria due to hypokalemia. The hypokalemia resulted from diuretic treatment. He had no family history of myopathy, and no diarrhea and vomiting. The neurological examination revealed painful quadriplegia. The blood pressure was 160/74 mm Hg. Laboratory examination showed hypokalemic and hypochloremic metabolic alkalosis (serum K 1.5 mEq/l, serum Cl 89 mEq/l, base excess + 20.9, HCO3- 44.9 mmol/l, pH 7.563) and marked elevations of serum CPK, LDH, GOT, GPT and myoglobin. Endocrinological and renal functions were normal. Muscle biopsy revealed marked necrosis with remarkable phagocytosis and vacuolar degeneration. The cessation of diuretics and intravenous infusion of potassium chloride resulted in a marked improvement in clinical and laboratory findings. The diuretics-induced hypokalemic myopathy is rare in the literature.

Effects of administration of triflupromazine were evaluated in 11 adult domesticated camels (Camelus dromedarius) weighing 403 +/- 29.5 kg (Mean +/- SE). Six camels were used to evaluate sedative properties of the drug and its effects on haematological and blood biochemical parameters. In the remaining 5 camels, effects on haemodynamics, acid base status and blood gases were studied. In all the animals triflupromazine was administered intramuscularly in the gluteal region at the rate of 2 mg/kg. Camels voluntarily sat down 48.9 +/- 5.4 min after administration of the drug but stood up again if disturbed. Drowsiness, drooping of lower lip and salivation were evident. The animals stood on their own and started walking with ataxia after 159 +/- 7 min and recovered completely from the effect of drug within 259 +/- 23 min. The drug caused a significant tachycardia and a moderate hypotension. The decrease in central venous pressure was also significant. Rectal temperature, respiratory rate, acid base status, blood gases, haemoglobin concentration, packed cell volume, total erythrocyte count, total leucocyte count, differential leukocyte count, blood urea nitrogen, plasma alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, blood glucose and plasma concentrations of sodium, potassium, chloride and inorganic phosphate were not significantly affected by triflupromazine.

Biochemical components usually evaluated in seminal plasma are lower than those in blood serum. In this study the concentration of different constituents in seminal plasma has been analyzed: creatinine, urea, glucose, uric acid, sodium, potassium, triglycerides, cholesterol, bilirubin, alkaline phosphatase, glutamic oxalacetic transaminase (SGOT), glutamic pyruvate transaminase (SGPT), cholinesterase, creatin phospho chinase (CPK), gamma glutamyl transpeptidase, lactic dehydrogenase (LDH), proteins, in comparison with the concentrations of the same constituents in blood. With the exception of uric acid, all the biochemical components in the seminal plasma were either significantly higher or lower than in blood serum, an index of the complexity of the mechanism regulating the presence and distribution of the single components in seminal plasma compared with blood serum. Isoelectro-focussing for proteins showed, in seminal plasma, a higher quantity of fragments and a different distribution of this in comparison with blood serum.

1. Plasma calcium, magnesium, inorganic phosphorus, sodium and potassium concentrations, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and creatine kinase activities were determined in young and adult non-pregnant non-lactating, early and late non-lactating pregnant and early, mid- and late non-pregnant lactating Danish landrace goats in five herds. The purpose was to determine the influence of pregnancy and lactation on the levels of these parameters and the effect of age and parity on the changes. 2. Calcium, phosphorus, alanine aminotransferase, alkaline phosphatase and aspartate aminotransferase decreased in late gestation. Magnesium and creatine kinase decreased in early lactating goats but increased in subsequent lactation periods. Sodium and potassium fluctuated little during pregnancy and lactation. Calcium, magnesium and potassium profiles were inversely, while phosphorus was directly, proportional to parity. 3. There were significant differences in most ions and enzymes between goats of different herds (within the same physiological state). 4. The transferases and creatine kinase were higher in young goats than in old ones, while alkaline phosphatase was unpredictably high or low in individual goats. 5. Alterations in the level of plasma electrolytes and enzyme activities occur due to pregnancy and lactation and the degree depends on age and parity, influenced also by environment.

A number of chemicals are known to potentiate the hepatotoxicity of carbon tetrachloride. The halocarbon trichloroethylene was shown in a previous study to enhance both carbon tetrachloride-induced toxicity and lipid peroxidation in isolated hepatocytes. In this study three other chlorocarbons have been investigated in order to determine whether this interaction was peculiar to trichloroethylene or common to chlorinated solvents. Hepatocyte suspensions were exposed to carbon tetrachloride at subthreshold levels of toxicity and various concentrations of 1,1,1-trichloroethane, tetrachloroethylene, and chloroform over an eightfold concentration range. Plasma membrane preparations were exposed to tetrachloroethylene and carbon tetrachloride and effects on Mg(2+)- and Na(+)-K(+)-ATPase activities determined. None of the treatments alone caused statistically significant toxicity. Combined treatments resulted in toxicity as demonstrated by potassium ion, alanine aminotransferase, and lactate dehydrogenase leakage from the cells on coincubation of carbon tetrachloride with each of the other halocarbons studied. Only tetrachloroethylene and chloroform were found to potentiate lipid peroxidation, however. In liver plasma membranes no changes in Na(+)-K(+)-ATPase were observed with any of the treatments and only the highest dose of tetrachloroethylene was able to inhibit Mg(2+)-ATPase activity. There was no increase in this inhibition on coincubation with carbon tetrachloride, which does not support involvement of ATPases in combined halocarbon toxicity. In conclusion, the data suggest a mechanism of action common to this class of chemical although its specific nature remains to be established.

62 specimens of cystic fluid drawn back by ultrasound guided needle-aspiration in 37 males and 25 females were evaluated biochemical analysis including magnesium, calcium, phosphorus, chloride, uric acid, total protein, sugar, urea, creatinine, sodium, potassium, total cholesterol, AST, ALT, ALP, ACP, PAP, alpha-amilasys. In our study Cl, Na and sugar showed similar concentrations in the two fluids. Uric acid, and urea were more concentrated in the cystic fluid while Mg, Ca and total protein were more pronounced in the blood. The results obtained seem to indicate that simple renal cyst could originate from glomerular proximal tubulus part of the nephron as consequence of an obstructive cause.

In the period of January 1978 to October 1988, 32 Le Veen shunts (LVS) were implanted in 20 patients, out of which 16 were alcoholic cirrhotics and 4 postnecrotic cirrhotics. In the present study, we correlated preoperative laboratory data of these patients with their postoperative evolution, comparing the clinical results of patients who survived more than 30 days (13 patients = 65%) with the results of those who died within the same period (7 patients = 35%). For that matter, 14 laboratory tests were performed in order to measure the serum levels of hematocrit, hemoglobin, urea, creatinine, sodium, potassium, bilirubin, albumin, AST, ALT, alkaline phosphatase, fibrinogen, gamma GT and prothrombin activity. After statistical analysis, we observed that 6 of the 14 tests performed could be considered of prognostic value in the following decreasing order of importance: fibrinogen, alkaline phosphatase, prothrombin activity, urea, gamma GT and bilirubin. We observed that all the 7 patients who died prematurely presented 3 or more of these levels altered, when compared with standard values. Based on these data, we concluded that serum levels of fibrinogen, alkaline phosphatase, urea, gamma GT, bilirubin and activity of prothrombin proved to be important factors in determining the prognosis of immediate survival in cirrhotic patients who underwent LVS implantation. We also concluded that when 3 or more of these factors are altered, the implant of LVS is contraindicated, whatever clinical criteria for indication and contraindication were taken into account.
