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.

The present study was undertaken to investigate the effects of acute 2,4-dichlorophenoxyacetic acid (2,4-D) intoxication (0.6 g/kg, po) on lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, amylase, creatinine, glucose, total protein and albumin levels in rats. Serum levels of lactate dehydrogenase, alkaline phosphatase and creatinine increased from 1- to 4-fold at 5, 8 and 24 h after 2,4-D administration, whereas serum levels of aspartate and alanine aminotransferase were higher only at 8 and 24 h. Amylase levels were only increased 8 h after administration of 2,4-D and then returned to normal levels. In contrast, 2,4-D reduced the serum levels of glucose and total protein 5, 8 and 24 h and serum albumin levels 5 h after herbicide intoxication. Thus, acute intoxication with 2,4-D disrupts serum levels of several enzymes and components which are considered to be indicators of tissue injury. Most likely these alterations mainly reflect hepatic and muscle tissue damage induced by the herbicide, but significant pancreatic and kidney toxicity may also have occurred.

We have established an improved model of fulminant hepatic failure in dogs. Buthionine sulfoximine is used to inactivate glutathione synthesis, and small increments of acetaminophen are given intravenously to maintain the plasma level at approximately 200 micrograms/ml for 20 hr. This regimen produces severe liver injury along with many of the features seen in humans with acetaminophen poisoning. The first sign of impending liver failure is hypoglycemia. This occurs about 15 hr into the experiment and requires treatment with a continuous infusion of glucose. Between 15 and 20 hr, serum ALT activity begins to rise, indicating the onset of liver necrosis. Over the following 15 to 20 hr ALT activity continues to rise and is accompanied by an increase in bilirubin, a prolongation of the prothrombin time and the development of fetor hepaticus. Thirty to 48 hr after the initial acetaminophen dose, the animals begin to exhibit symptoms of encephalopathy and progress from lethargy to the inability to maintain posture and then coma, seizures and death. Liver biopsy specimens obtained at several stages throughout the study showed progressive necrosis, ultimately resulting in the complete destruction of zones 2 and 3.

Lupinosis is a mycotoxicosis caused by the ingestion of toxins produced by the fungus phomopsis leptostromiformis which grows on lupin plants. An outbreak of natural lupinosis in lambs occurred in Caceres, Spain. Clinical signs were inappetence, depression, constipation, weakness and different degrees of jaundice. Blood samples were analysed every 7 d for 5 w for hematocrit, total protein, glucose, total bilirubin, and GOT, GPT and alkaline phosphatase activities. The last 4 parameters were increased and returned to normal values after 2-3 w. The liver was swollen and a bright yellow color; microscopically fatty metamorphosis, necrotic areas and infiltration of polymorphonuclears were observed. This is the first time that lupinosis is described in Spain.

Overtraining may be one frequent cause of stagnation or decrease in performance capacity of athletes. Israel (19) differentiates between addisonoid (parasympathetic) and basedowoid (sympathetic) overtraining, characterized by inhibition or excitation. We tried to induce an overtraining syndrome in 8 experienced middle- and long-distance runners, based on an increase in training volume from an average 85.9 km (week 1) to 115.1 km (week 2) and 143.1 km (week 3) to 174.6 km per week (week 4). The influence of this training on cardiovascular, metabolic and hormonal parameters was examined with special respect to plasma and urinary catecholamines. Laboratory testing including graded treadmill running was performed on the days 0, 14 and 28. Training was held six days each week, with nearly 30 km per day in the fourth week. A stagnation in endurance performance capacity (running velocity at the aerobic-anaerobic transition range) and a decrease in maximum working capacity were observed in 6 and a stagnation in 2 of the 8 sportsmen, indicated by a decrease in total running distance from 4719 + 912 m to 4361 + 788 m during incremental treadmill ergometry. The sportsmen could neither improve nor could they even approximately reach their personal records during the subsequent competitive season. Subjective complaints, classified on a four-point scale, increased from 1.2 (week 1) to 3.2 in week 4. Glucose, lactate, ammonia, glycerol, free fatty acids, albumin, LDL, VLDL cholesterol, hemoglobin level (transient), leukocytes, and heart rate (before and during exercise) decreased significantly. Urea, creatinine, uric acid, GOT, GPT, gamma-GT, serum electrolytes (except phosphate and calcium) remained constant at the measuring times, CPK was elevated.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

The effects of age, sex, pregnancy, were analyzed and data from fasted and fed animals were compared in a population of cynomolgus macaques. No significant sex effects were observed for biochemical values and no changes were found in male hematological parameters in relation to age. Most values of females during pregnancy were within normal ranges. Comparison between fed and fasted animals showed that several biochemical parameters (e.g., ALT, glucose, CPK, LDH) and several hematological parameters (e.g., monocytes, eosinophils, basophils, hemoglobin, MCV, MCHC, and MCH) were affected by food intake.

The 3-years efficacy and safety of the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor simvastatin (S) (previously called synvinolin or MK-733) has been studied in single and combined therapy with cholestyramine (C) in 48 hypercholesterolaemic patients. Plasma lipids, lipoproteins and apolipoproteins A-I and B, and blood safety tests (haematology, liver function, creatine phosphokinase (CPK), creatinine, blood glucose and thyroid function) were determined regularly throughout the study. Extensive ophthalmological examinations with particular focus on the lens were done before initiation of therapy and at every 6 months during drug treatment. Maximal reductions of mean plasma total cholesterol concentration (34% with S; 47% with S + C) and low-density lipoprotein (LDL)-cholesterol concentration (42% with S; 56% with S + C) were achieved after 4 weeks on full-dose therapy. During continued treatment, years 1 through 3, the reduction of mean plasma total cholesterol was 26-29% with S alone, and 31-41% with S + C. Significant reductions of plasma triglycerides (15-27%) and very low density lipoprotein (VLDL) triglycerides (10-27%) were achieved in the group treated with S as single therapy. In this group there was also a significant increase (10-14%) of high-density lipoprotein (HDL)-cholesterol. In liver aspartate (AST) and alanine (ALT) aminotransferases, as well as alkaline phosphatase (ALP), minor and variable, but usually transient, increases were seen. Repeated ophthalmological examinations did not demonstrate any drug-related side effects. It is concluded that simvastatin is a safe and efficient cholesterol-lowering drug for long-term therapy, both as a single drug and in combination with cholestyramine.
