After a chloroform intraperitoneal injection, lactate dehydrogenase, alanine aminotransferase and particularly aspartate aminotransferase serum activities are much more raised in deficient animals. Liver ornithine decarboxylase (ODC) activity normally decreases in rats between the 4th. and the 7th. month after the weaning. In vitamin A deficient animals, basal values of the enzyme activity are lower and the decrease is deeper. But even at month 7, liver sustains a partial capacity of ODC recovery if retinol is fed during 15 days. Chloroform administration strongly enhances liver ODC activity in normal rats. In the deficiency, stimulation is lower in absolute value but relatively higher if referred to basal level. After retinol refeeding, chloroform stimulates enzyme activity to nearly normal values. Vitamin A deficiency impairs obviously liver ODC activity and its response to chloroform stimulation in rats, but the stroke is at least partially reversible in our conditions. Moreover, deficient animals maintain a non negligible capacity of ODC response under chloroform stimulation.

A 46-year-old woman, who had been treated with anti-arrhythmic drugs and digitalis for mitral stenosis and paroxysmal atrial fibrillation, suddenly developed severe abdominal pain and nausea. There was tenderness around right CVA. BUN and serum-creatinine were elevated, 57 mg/dl and 4.5 mg/dl respectively. She was in acute renal failure (ARF). WBC, GOT, GPT, LDH were also elevated. Abdominal ultrasonography showed normal-size right kidney (12 cm) and atrophic left kidney (8.5 cm). Selective right renal angiography revealed right renal arterial embolism, suggesting that ARF developed from right renal infarction complicated by left atrophic kidney. Renal scintigram using 99mTc-DTPA indicated non-function type left kidney. Because of the high risk of surgery, she received anticoagulant therapy. Fifteen days later, BUN and serum-creatinine returned to 14mg/dl, 2.2mg/dl, respectively.

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.

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)

The chronic toxicity of potassium clavulanate (CVA-K) and BRL28500 were evaluated using dogs in 26-week intravenous administration studies followed by a 5-week off-dose period. The doses for CVA-K and BRL28500 were 10, 20, 50 and 100 mg/kg (p.f.a.), and 80, 160, 320 and 800 mg/kg (p.f.a.) respectively. There were no deaths in either of the groups. For general condition, dogs dosed with CVA-K at 100 mg/kg showed reddening of the skin and mucous membranes, shaking of the head, facial oedema, a decrease in food intake and a reduction in body weight. Also some dogs of the same group showed decreased spontaneous activity, emaciation and signs of dehydration. In the BRL28500 treatment groups, there was reddening of the skin and mucous membranes, vomiting and salivation at 800 mg/kg. Urinalysis of dogs dosed with CVA-K showed occasional dark yellow coloration of the urine. There was also a very weak and equivocal response or positive reaction for protein, occult blood, and urine sugar in some animals at 100 mg/kg. Some dogs dosed with BRL28500 also showed either a very weak and equivocal response or slight positive reaction for occult blood at 320 mg/kg and above, and dark yellow coloration of the urine at 800 mg/kg. Haematological examination of the CVA-K groups showed increases in leukocyte count and platelet count at the highest dose of 100 mg/kg. No haematological abnormalities were noted in any of the BRL28500 groups. Serum biochemical studies of dogs dosed with CVA-K revealed a decrease in total protein at 50 mg/kg and above, and increases in Al-P, total bilirubin, GPT, BUN and creatinine at 100 mg/kg. In the BRL28500 treatment groups, there were increases in total cholesterol and triglyceride at 160 mg/kg and above. In dogs dosed with CVA-K there was an increase in liver weight at 100 mg/kg. Histopathological examination showed a ground glass-like appearance of the hepatocyte cytoplasm and also altered distribution of PAS positive material at 50 mg/kg and above. In the BRL28500 groups, there was an increase in liver weight at 320 mg/kg and above. There were the same ground glass-like appearance in hepatocytes and altered distribution of PAS positive material at 800 mg/kg. In view of the above results, the maximum non-effect dose levels in the present studies were considered to be 20 mg/kg for CVA-K and 80 mg/kg for BRL28500.(ABSTRACT TRUNCATED AT 400 WORDS)

The authors have carried out laboratory and clinical studies on the BRL 25000 granule (containing 2 parts amoxicillin and 1 part clavulanic acid). The antibacterial activity of BRL 25000 against 29 clinically isolated strains of S. aureus, 30 E. coli and 30 K. pneumoniae were measured by the agar dilution method using an inoculum size of 10(6) cells/ml. beta-Lactamase production was detected by the Nitrocefin method. The MICs of BRL 25000 against S. aureus ranged from 0.2 approximately 12.5 micrograms/ml, with the majority of strains being inhibited by 1.56 micrograms/ml or less. Seven beta-lactamase producing strains of S. aureus were all inhibited by less than 12.5 micrograms/ml. The range against E. coli was 1.56 approximately 100 micrograms/ml, with the majority inhibited by 6.25 micrograms/ml or less. Fifteen beta-lactamase producing strains of E. coli were inhibited by 6.25 approximately 100 micrograms/ml and the majority by 25 micrograms/ml or less. All strains of K. pneumoniae were beta-lactamase producers and the MIC distribution against K. pneumoniae was 1.56 approximately 50 micrograms/ml, with a majority inhibited by 3.13 micrograms/ml or less, 96% of strains, were inhibited by less than 6.25 micrograms/ml. Against K. pneumoniae, BRL 25000 showed a 8 to 16-fold superiority when compared with AMPC. In a pharmacokinetic study, BRL 25000 granules were orally administered to children in the fasting state at single doses of 7.5 mg/kg and 20 mg/kg. The peak serum levels of AMPC were 6.13 and 6.94 micrograms/ml approximately 1 hour after administration and decreased with half-lives of 1.08 and 0.97 hours, respectively. The corresponding serum levels of CVA were 1.16 and 1.90 micrograms/ml at 1 hour after administration, with half-lives of 0.99 and 0.87 hour, respectively. In clinical studies, the BRL 25000 granule was effective in 39 cases of bacterial infection out of a total of 41 treated. Side effects were limited to 2 cases of diarrhea and minor changes in laboratory findings were elevation of serum GOT (1 case), elevation of serum GPT (1 case), and eosinophilia (2 cases).

In view of recent interest in the relationship of haematocrit and blood viscosity to hypertension and vascular disease, we have analysed retrospectively the relationship of haematocrit to blood pressure, vascular complications and other variables in 2,381 patients referred to the Glasgow Blood Pressure Clinic. Haematocrit correlated negatively with age and systolic pressure in men, and positively with age and systolic pressure in females. Positive correlations were found in both sexes between haematocrit and serum alanine aminotransferase (possibly due to mutual correlation with alcohol); and between haematocrit and overweight (Quetelet Index) but not obesity (Ponderal Index). Increased haematocrit was also associated with cigarette smoking; and with history of angina, myocardial infarction and intermittent claudication in females. No correlation was observed between haematocrit and history of stroke. These findings suggest that prospective studies of haematocrit in hypertensives may be of interest.

We attempted to make a basic model to investigate a series of factors that induce histological changes in systemic hypoxia-reoxygenation injuries. At first, we set the experimental conditions for hypoxia and the hypoxia-reoxygenation models as follows: respiration volume: 1.5 ml/stroke, respiratory frequency: 80 times/min, oxygen concentration: 14%. Next, Male SPF Wistar rats were anesthetized with pentobarbital sodium. For artificial ventilation, a cannula was inserted in the trachea and connected to the rodent ventilator through two flow meters to allow mixing of 100%N2 and 95%O2-5%CO2 gases at a desired ratio. The influence of hypoxia-reoxygenation was studied and evaluated histologically and biochemically. The rats were placed under the hypoxic condition for either 3 or 6 hr. Then, oxygen partial pressure was restored to 21% followed by reoxygenation for either 3 or 6 hr. Then the rats were sacrificed, and the pituitary, adrenals, heart, stomach and kidneys were removed. The results were as follows: 1) GPT activities were increased by a load of hypoxia, but no influence of reoxygenation was detected. 2) Under the condition of experimental hypoxia, the weights of the pituitary and adrenals increased significantly. 3) The histological findings indicated that 6-hr hypoxia followed by 3-hr reoxygenation induced hypoxia-reoxygenation injuries mostly affecting the anterior pituitary and adrenal medulla.

We evaluated clinical effects and toxicities of a combination of fosfomycin (FOM) and clavulanic acid/ticarcillin (CVA/TIPC) for treatment of infections complicated with hematological disorders in 61 patients. Fifty-eight patients were evaluable, including 40 with acute leukemia, 13 with malignant lymphoma and 5 with other hematological disorders. Clinical efficacies were excellent in 21 cases, good in 13 cases, fair in 2 cases and poor in 22 cases. The efficacy rate was 58.6% (34 cases/58 cases). This treatment was also effective in 12 of 20 cases in which granulocyte counts were less than 500/microliters through the course of administration. No subjective side effects were observed. Abnormal values in laboratory tests were noted in 1 case. Mild elevations of GOT and GPT were observed. Thus, the combination of FOM and CVA/TIPC is an effective and safe regimen for the treatment of infections in patients complicated with hematological disorders.

The effect of long-term 'corn peptide (CP)' ingestion on alcohol metabolism was investigated in stroke-prone spontaneously hypertensive rats (SHR-SP) with alcohol loading. Long-term CP ingestion in the EtOH/CP group did not significantly increase plasma GOT and GPT activities but markedly increased hepatic ADH and ALDH activities. Intragastric CP administration prior to a dose of 1.0 g/kg ethanol significantly lowered the blood ethanol concentration in SHR-SP which had been loaded with ethanol for a long time. Compared with non-loaded SHR-SP (control group), the rats loaded for a long time with ethanol (EtOH group) showed high concentrations of taurine, glycine and histidine in the plasma. The plasma threonine and proline concentrations were significantly elevated by long-term CP ingestion (EtOH/CP group), but the plasma alanine concentration was rather decreased. These results suggest that short- or long-term CP ingestion may enhance the alcohol metabolism within the body because of an increase in ADH and ALDH activities as well as the alleviation of alcohol-related hepatic injury.
