A 6-year-old girl with cerebral palsy developed conscious disturbance and generalized convulsion after one-hour hot herb drug bath. Physical examination on admission revealed rectal temperature 41 degrees C, hot skin, respiration 46/min, regular heart beat 98/min, BP 130/60 mmHg, Glascow coma scale 4 (E2M1V1), soft and flat abdomen, no hepatosplenomegaly, no skin rash, no focal neurological sign, increased generalized muscle ton. Laboratory data showed CBC: WBC 20400 cumm (Neutrophils 31%, Lymphocytes 69%), Hb 11.6gm%, ESR 11 mm/hr, arterial blood gas: PH 7.077, PO2 43mmHg, PCO2 57.1mmHg, HCO3- 16 mEq/L, BE-11.5mEq/L, serum sodium 143 mEq./L, potassium 5.2 mEq/L, chloride 101 mEq/L, free calcium ion 3.8mg%, GOT 63IU/L, GPT 263 IU/L, amylase 193 IU/L, alkaline phosphatase 388 IU/L, LDH 1245 IU/L, CPK 677 IU/L, total bilirubin 0.8 mg/dl, direct type 0.1 mg/dl, BUN 18 mg/dl, Glucose 35 mg/dl. Urinalysis revealed proteinuria( ) trace hematuria and pyuria, but no cast. Lumbar puncture is within normal limits. Bacteriology including blood and CSF are normal. Multiple organ failure was noted at that time. Intensive cooling methods were performed including central and peripheral cooling. We used luminal and valium to control the seizure. Condition didn't improve. Afterwards cardiopulmonary arrest developed. Patient expired 8 hours after admission despite of resuscitation. Heat stroke in infancy and childhood is different from that in adulthood. The predisposing factors are high ambient temperature, dehydration, very young baby, sweat gland dysfunction, or ectodermal dysplasia. Definition of heat stroke includes 1) rectal temperature above 41 degrees C, 2) behavioral change, 3) warm skin, wet or dry.(ABSTRACT TRUNCATED AT 250 WORDS)

Pharmacokinetics and clinical studies of imipenem/cilastatin sodium (IPM/CS), a combined preparation of a new carbapenem antibiotic and a dehydropeptidase-I inhibitor, respectively, were carried out in neonates and premature infants in a joint study by a co-research group. 1. Peak blood levels of IPM/CS when administered at 10 mg/10 mg/kg or 20 mg/20 mg/kg by 30- or 60-minute intravenous drip infusion were achieved at the end of infusion. A dose response was clearly observed between the doses and the peak levels achieved. 2. The areas under the blood concentration time curve (AUC) of CS were greater than those of IPM in most patients. Blood half-lives of IPM and CS tended to be longer in younger neonates and premature infants than in older subjects. The blood half-life of CS tended to be longer than that of IPM. 3. Cumulative urinary recovery rates of CS were greater than those of IPM, cumulative urinary recovery rates tended to be greater in older neonates and premature infants than younger subjects. 4. One hundred and thirteen patients were treated for bacterial infections with IPM/CS and 32 patients were treated prophylactically. Daily doses of IPM/CS ranged from 9 mg/9 mg/kg to 150 mg/150 mg/kg. 5. Clinical efficacies of IPM/CS were evaluated in a total of 56 patients with identified etiologic pathogens. The efficacy rate was 98.2% with 33 patients rated as excellent, 22 patients as good and 1 patient as fairly good. (Diagnoses were sepsis in 10 patients and meningitis in 2 patients, etc.) Fifty-seven patients with no identified etiologic pathogens were rated as excellent for 22 patients, good for 34 patients and fairly good for 1. The efficacy rate in these patients was 98.2%. Thirty-two patients were treated prophylactically and the results obtained were satisfactory. 6. Bacteriologically, the eradication rate was 94.5% in 56 patients; i.e., 52 were eradicated, 2 were decreased, 1 persisted and 1 was unknown. 7. Adverse effects were observed in 7 (4.4%) of 160 patients, i.e., 2 patients had diarrhea and 2 patients had rash, etc. Abnormal laboratory data considered related to the therapy occurred in 28 (17.6%) of 159 patients, with 10 patients with eosinophilia (6.3%) and elevation of GOT and/or GPT, etc. All these were non serious, and all values returned to normal after discontinuance of therapy. An abnormal prothrombin (PIVKA II) was observed in 1 of 10 patients tested.(ABSTRACT TRUNCATED AT 400 WORDS)

After racing 722 m, 16 Greyhounds were evaluated to determine changes in hematologic, biochemical, blood-gas, and acid-base values following exercise. Values were determined before racing (T0), immediately after racing (T1), and 3 hours after racing (T2). Significant changes detected immediately after racing included increased heart rate, respiratory rate, and rectal temperature. Significant changes in hematologic values included increases in PCV, total plasma protein, hemoglobin, RBC, WBC, neutrophils, and lymphocytes. Change was not detected in values for monocytes, eosinophils, and neutrophil/lymphocyte ratio. Other increases included those for plasma concentrations of sodium, chloride, calcium, lactic acid, aspartate transaminase, alanine transaminase, alkaline phosphatase, creatine kinase, lactate dehydrogenase, and glucose. Concentrations of potassium and urea did not change. Measurement of blood-gas and acid-base status revealed significant increases in PaO2 and base deficit, whereas PaCO2, pH, and bicarbonate decreased. Three hours after exercise, all vital signs and blood-gas and acid-base values, except for PaCO2, which was still slightly low, had returned to baseline (T0) values. Most biochemical values had also returned to baseline, although sodium, chloride, aspartate transaminase, and creatine kinase were still high, and urea was low. Many hematologic values were still different from baseline values, with high values for WBC, neutrophils and neutrophil/lymphocyte ratio, and low values for PCV, total plasma protein, hemoglobin, RBC, and lymphocytes.

The influence of selenium on cis-diamminedichloroplatinum(II) (c-DDP) nephrotoxicity in mice and rats was assessed, using single doses of both compounds. Sodium selenite, 2 mg of selenium per kg, given 1 h before c-DDP, greatly reduced blood urea nitrogen and creatinine levels and morphological kidney damage in both BALB/c mice and Wistar rats, while administration 1 h after c-DDP did not. Liver toxicity of selenium was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase and by routine histology. No liver damage was observed in animals treated with sodium selenite, 2 mg of selenium per kg, and physiological saline or c-DDP. Pretreatment with sodium selenite did not reduce the antitumor activity of c-DDP against MPC 11 plasmacytoma or Prima breast tumor in BALB/c mice. The present results indicate that sodium selenite may provide protection against c-DDP nephrotoxicity, when it is given before c-DDP. Moreover, selenium has an antineoplastic activity against several tumors. The combination of these qualities may open new perspectives in cancer chemotherapy.

Groups of 21 male and 21 female Sprague-Dawley (SD) rats were fed diets containing pyriproxyfen at concentrations of 0, 80, 400, 2,000 and 10,000 ppm for 6 months. No death was found in any group. Alopecia in the neck and/or back, and soft feces were noticed in both sexes fed 10,000 ppm. A marked decrease in body weight gain was observed in both sexes fed 10,000 ppm throughout the treatment period, accompanying a decrease in food-consumption and an increase in water-intake during the initial stage of treatment. In terms of urinalysis, proteinuria, increases in K excretion, and, in number, yellowness or browish-yellowness in appearance, were observed in both sexes fed 10,000 ppm. In females fed 10,000 ppm, increases in bilirubin, Na excretion and specific gravity, and a decrease in ketone bodies, were observed. In hematology, decreases in erythrocyte count, hemoglobin concentration and hematocrit value, were observed in both sexes fed 10,000 ppm and in males fed 2,000 ppm. Also, an increase in MCH (in males), decreases in MCHC and platelet count (in females) were observed in 10,000 ppm group. Blood biochemistry revealed increases in total protein, albumin, alpha 2-globulin fraction, blood urea nitrogen, calcium (in both sexes fed 10,000 ppm), A/G ratio (in males fed 2,000 and 10,000 ppm), total cholesterol, phospholipid (in males fed 2,000 and 10,000 ppm, and in females fed 10,000 ppm), sodium (in females fed 2,000 and 10,000 ppm), gamma-glutamyl transpeptidase activity (in males fed 10,000 ppm) and alpha 1-globulin fraction (in females fed 10,000 ppm), and decreases in glucose, GOT (in both sexes fed 10,000 ppm), beta-globulin fraction (in males fed 2,000 and 10,000 ppm, and in females fed 10,000 ppm), GPT (in females fed 2,000 and 10,000 ppm), triglyceride, potassium (in males fed 10,000 ppm), and cholinesterase activity (in female fed 10,000 ppm). In organ weight, increases in liver (in males fed 2,000 ppm and 10,000 ppm, and in females fed 10,000 ppm), kidney (in both sexes fed 10,000 ppm) and thyroid (in females fed 10,000 ppm) and a decrease in pituitary (in females fed 2,000 and 10,000 ppm) were observed. Gross pathology revealed a higher incidence of blackish-brown coloration of the liver, and a lower incidence of accentuated lobular pattern of the liver (in males fed 10,000 ppm). An enlargement of the liver was seen in a few of both sexes fed 10,000 ppm. Histopathological examination showed that the sole effect attributable to treatment of this compound was on slight hypertrophy in the liver of both sexes fed 10,000 ppm, with a higher incidence.(ABSTRACT TRUNCATED AT 400 WORDS)

Biochemical studies were conducted in experimentally induced selenium toxicity in recently weaned guinea pigs. A significant drop in blood glucose level, in comparison to controls, was observed in animals fed selenium-enriched barley (organic form) as well as those fed ordinary barley mixed with sodium selenite (inorganic form). Estimation of total serum proteins also revealed a significant drop in both these groups. SGOT (EC 2.6.1.1) activity was comparatively lower but no significant alteration was noticed in SGPT (EC 2.6.1.2). The erythrocytic glutathione peroxidase activity was significantly increased in inorganic selenosis followed by that in organic one, in comparison to controls. All these alterations were of mild degree in guinea pigs which were given sodium arsenite (10 ppm) along with sodium selenite (30 ppm) in the feed.

A detailed biochemical analysis has shown that during larval development on artificial medium, the amounts of K+, Na+, and Ca2+ in the hemolymph of healthy Choristoneura fumiferana varied from 85 to 110 mg/100 mL, 29 to 33 mg/100 mL, and 4.8 to 7.3 mg/100 mL, respectively. Similar results were obtained with Malacosoma disstria. Intoxication by Bacillus thuringiensis "H3a,3b" (B. t.) considerably modified the amounts of the cations. Thus, after 4 h, the quantity of K+ in M. disstria increased from 99 to 229 mg/100 mL and Na+ from 26.5 to 50.3 mg/100 mL while that of Ca2+ decreased from 5.8 to 1.2 mg/100 mL. Similar results were observed with C. fumiferana, but these variations occurred after 2 to 4 days of B. t. intoxication. The variations detected during the bacillosis, with respect to the cationic composition of the insect hemolymph, are rapidly detectable, well before light microscope observation can confirm the presence of this intoxication. Aspartate aminotransferase, alanine aminotransferase, alpha-hydroxybutyrate dehydrogenase, and isocitrate dehydrogenase activity fluctuated very slightly in the hemolymph of either healthy or bacillosed larvae of the two insects under study. These results suggest that it is possible to diagnose biochemically the presence of a B. t. intoxication in lepidopteran forest pests following treatments by this biological insecticide for their control.

Pharmacokinetic, bacteriological and clinical studies on imipenem/cilastatin sodium (IPM/CS) were performed in neonates. The results were as follow: 1. A total of 27 patients consisting of 17 mature and 10 immature infants were treated with IPM/CS. Each dose was 20 mg/20 mg/kg, and it was administered 2 approximately 3 times daily, in a 1-hour intravenous drip infusion for 3 approximately 12 days. The clinical efficacy of IPM/CS in 10 patients with bacterial infections (2 with sepsis, 3 with suspected sepsis, 2 with pneumonia, 2 with urinary tract infection and 1 with acute omphalitis) was evaluated as excellent in all patients, with an efficacy rate of 100%. All 5 causative organisms found in 5 patients (Staphylococcus aureus in 1, Staphylococcus epidermidis in 1, Escherichia coli in 2 and Flavobacterium meningosepticum in 1) were eradicated. Among 27 patients administered IPM/CS, adverse reactions were observed in 2 patients. These were rash and diarrhea. As for abnormal laboratory test values, elevations of GOT and GPT were observed. 2. MICs of IPM against 14 clinical isolates (S. epidermidis 1, S. aureus 6, Streptococcus agalactiae 4, E. coli 1, Enterobacter cloacae 1 and F. meningosepticum 1) from neonatal patients with bacterial infections were examined. IPM showed good antibacterial activity comparable to that of cefotaxime against S. agalactiae; however, the activity against methicillin-resistant S. aureus was poor. 3. Serum levels of IPM and CS were investigated in a total of 22 patients consisting of 15 mature and 7 immature infants after 20 mg/20 mg/kg of IPM/CS was administered. IPM and CS produced peak serum levels at the end of the drip infusion. In mature infants, peak serum levels of IPM and CS were 31.8 micrograms/ml (17.1 approximately 59.0 micrograms/ml) and 59.9 micrograms/ml (35.6 approximately 99.0 micrograms/ml), respectively. In low birth weight infants, these were 25.0 micrograms/ml (16.8 approximately 41.8 micrograms/ml) and 55.2 micrograms/ml (33.8 approximately 82.4 micrograms/ml), respectively. Half-lives of IPM and CS were 1.0 approximately 2.7 hrs. and 0.9 approximately 7.4 hrs. in mature infants, and 1.6 approximately 3.0 hrs. and 1.3 approximately 9.7 hrs. in immature infants, respectively. Generally the longer half-lives were observed in the younger neonates. Serum levels of CS remained higher and half-lives of CS were longer than those of IPM. The pharmacokinetics in neonates were different from those in adults or children.(ABSTRACT TRUNCATED AT 400 WORDS)

A new autoperfusion preparation was used to preserve six major organs simultaneously. In 7 Yorkshire white swine, the heart and lungs were separated and removed with the liver, pancreas, duodenum, and both kidneys en bloc while they were self-perfused. Fresh blood, glucose, electrolytes, heparin sodium, methylprednisolone, and a fat emulsion (Soyacal) were infused through the portal vein. No inotropic drugs were necessary. The organs survived for 18 to 37 hours (average survival, 24.6 +/- 2.7 hours [+/- standard error of the mean]). Aortic systolic pressure ranged from 78.5 +/- 5.5 to 98.7 +/- 11.8 mm Hg. Arterial oxygen tension ranged from 206 +/- 23 to 266 +/- 15 mm Hg and arterial carbon dioxide tension, from 20.1 +/- 2.7 to 32.1 +/- 4.9 mm Hg. Blood lactic acid levels decreased from 8.75 +/- 2.06 to 5.50 +/- 2.45 mmol/L at 24 hours. Urine output ranged from 25 to 82 mL/h. Blood urea nitrogen levels decreased from 9.17 +/- 0.59 to 4.67 +/- 1.08 mg/dL. Blood creatinine levels decreased from 1.34 +/- 0.10 to 0.57 +/- 0.22 mg/dL. Serum glutamicoxaloacetic transaminase levels increased from 73.4 +/- 26.3 to 194 +/- 179.5 U/L and serum glutamic-pyruvic transaminase levels, from 44.8 +/- 5.7 to 91 +/- 66.4 U/L. Red blood cell count ranged from 6.94 +/- 0.58 to 13.23 +/- 2.30 x 10(6)/microliters. Lung wet/dry weight ratios changed from 5.79 +/- 0.17 at the beginning to 6.25 +/- 0.16 at 24 hours. The technique for simultaneous multiorgan preservation presented here is simple, effective, and highly reproducible. This study appears to have produced one of the longest average survival times for autoperfusion.

The Kodak Ektachem DT 60 Analyzer, a compact tabletop analyzer, which is based on the multilayer film technology, has been evaluated to assess its suitability for veterinary use. For a period of 6 months more than 400 serum samples from dogs and cats were analyzed for the following 11 analytes: ALT, CK, AP, alpha-amylase, total bilirubin, glucose, urea, total protein, creatinine, sodium, and potassium. Results obtained with the DT 60 Analyzer were compared with those gained from a Hitachi 705 autoanalyzer and from an Eppendorf flame photometer. Precision study results (within-run precision and between-run precision) were generally very good. Comparisons with other methods were quite satisfactory. Good to very good correlation was found for nearly all the parameters. The analyzer is easy to use and has proved to be reliable. It can be used successfully in the determination of serum-analytes in dogs and cats.
