Microorganisms degrading carbazole (CA), a model substrate of heterocyclic nitrogen compounds in crude petroleum oil, were screened under microaerobic conditions, i.e. nitrogen gas substituted conditions. Eight bacteria were isolated and identified. For example, Bacillus sp. KUKK-4 degraded 31% of CA when cultivated for 28 days in a medium initially containing CA at 1000 mg/l with shaking under the microaerobic conditions.

Glomerulonephritis (GN) is a leading cause of chronic renal failure in dogs. However, little is known about the efficacy of available treatment options for GN in this species. The purpose of this study was to determine the effects of cyclosporine (Cy) administration on the outcome of naturally occurring GN in dogs. Thirteen dogs from 4 institutions were included in the study. Randomization of dogs into placebo-versus Cy-treated groups was stratified according to initial morphological diagnosis and contributing institution. Seven and 6 dogs were assigned to be given placebo or Cy, respectively. The initial Cy dose of 10 mg/kg every 24 hours was adjusted to maintain 24-hour trough, whole blood Cy concentrations between 250 and 400 ng/mL. There were no statistically significant differences between placebo- and Cy-treated groups with respect to serum total protein, albumin, urea nitrogen and creatinine, and plasma protein concentrations; platelet count; urine protein-creatinine ratio; endogenous creatinine clearance; 24-hour urine protein concentrations; or 24-hour urine protein-endogenous creatinine clearance ratio. However, PCV was significantly lower in the Cy-treated group. Decreased appetite, diarrhea, vomiting, weight loss, involuntary shaking, and thrombocytopenia were noted in both treatment groups; however, clinical signs in Cy-treated dogs subjectively were more severe. One Cy-treated dog developed gingival hyperplasia.(ABSTRACT TRUNCATED AT 250 WORDS)

Seven related Bernese Mountain Dogs developed a syndrome Characterized by progressive cerebellar and hepatic disease. Clinically, stiffness in the hind limbs, mild incoordination, and a slight head tremor were first noticeable when pups were 4 to 6 weeks old. The condition progressed, causing pups to assume a wide-based stance. Other signs included head bobbing, spontaneous nystagmus, and, finally, paresis. Hematologic findings included leukocytosis with a left shift; normocytic, normochromic anemia; hypoproteinemia, low serum creatinine, and urea nitrogen concentrations; excessive fasting plasma ammonia concentration; and an increase in concentration of serum bile acids. Portal venography performed on 1 dog revealed a small liver and extensive extrahepatic varicosities. Necropsy revealed cerebellar hypoplasia, nodular liver, extensive abdominal varicosities, and ascites. Histologically, degeneration and depletion of Purkinje's cells and vacuolation, degeneration, and nodular regeneration of hepatic tissues were evident. Preliminary analysis of the pedigree was suggestive of an autosomal recessive pattern of inheritance.

The paper describes shake flask culture optimization studies for the production of amylases by Thermomyces lanuginosus. The culture was found to produce maximally alpha-amylase and glucoamylase (18.4 & 11.2 units/ml), respectively when the medium contained rice flour (2% w/v) as carbon and corn steep liquor as nitrogen source with medium pH adjusted to 5.5 and incubated for 72 h under shaking conditions (150 rpm) at 50 degrees C.

The effect of germination on the protein content and in the level of specific activity of lipoxygenase-1 on seedlings of Santa Rosa, FT-2 and Davis soybean cultivars were studied. Soybean seeds of the three cultivars were germinated from 0 to 72 hours in a seed germinator at 30 degrees C temperature, 100% relative humidity, and absence of light. The seeds were then frozen in liquid nitrogen, freeze-dried and milled. The lipoxygenase-1 was extracted with 0.02M thris-HCI buffer at pH = 8.2 and 13% saccharose for 30 minutes at 4 degrees C without shaking. The highest levels of specific activity of lipoxygenase-1 per milligram of flour (dry basis) in the Santa Rosa, FT-2 and Davis cultivars were observed between 18 and 36, 18 and 24, and 0 and 12 hours, respectively. The polinomial quadratic model best fits the regression analysis of the variable levels of specific lipoxygenase activity for cultivar Davis (R2 = 0.9197). Although for cultivars Santa Rosa (R2 = 0.9041)., and FT-2 (R2 = 0.7486) the 4th degree polynomial model has shown the best fit. The protein content in the three cultivars studied reached the maximum values at 48h germination. The germination induced a relative increase of the protein content but caused a reduction of the level of specific lipoxygenase-1 activity.

Haematological and serum biochemical measurements in male spontaneously epileptic rats (SER; double mutants homozygous for zitter and tremor genes) were compared with the values for related rat strains. Some haematological values were low in TRM rats and total leukocyte counts were high in ZI and TRM rats. TRM rats showed higher total cholesterol, phospholipid, high-density lipoprotein cholesterol and calcium values, and lower albumin value than Kyo: Wistar rats. Zitter homozygous rats including SER exhibited low total cholesterol, phospholipid and high-density lipoprotein cholesterol values. The SER showed an increase in urea nitrogen, aspartate aminotransferase and alanine aminotransferase values, and a decrease in glucose value, suggesting deterioration of the whole body with age.

A simple and rapid method for the determination of amphetamine (AP) and methamphetamine (MA) in human hair was developed by headspace solid-phase microextraction (SPME) and gas chromatography with nitrogen-phosphorus detection (GC-NPD). The hair (1 mg) was dissolved in 0.2 ml of a 5 M sodium hydroxide solution in a tightly sealed vial by shaking at 75 degrees C for about 5 min. In order to adsorb AP and MA on the SPME fiber, 100 microm of polydimethylsiloxane fiber was exposed to the headspace of the vial, and the vial was heated at 55 degrees C for 20 min. Then the fiber was removed from the vial and inserted into the injection port of the GC-NPD system using a CBJ-17 capillary column. The compounds adsorbed on the fiber were analyzed by exposing the fiber at 220 degrees C for 30 s in the GC injection port. By using this method, AP and MA in human hair could be analyzed simply and rapidly without any interference from coexisting substances. The percentages of AP and MA extracted from human hair by the SPME method were 48 and 62%, respectively, and relative standard deviations were below 10% (n=5). The calibration curves for AP and MA were linear in the ranges of 0.4-15 and 4-160 ng/mg hair, respectively. The detection limits of AP and MA at a signal-to-noise ratio of three were 0.1 and 0.4 ng/mg hair, respectively. This method could be applied to the analysis of an abuser's hair sample.

The composition of No. II medium obtained with shaking cultivation contained three factors: nitrogen source, carbon source, and inorganic salts. The relationship between component factors (x(i)) of the media and spore numbers (y) of Bacillus thuringiensis (Bt) was demonstrated by the orthogonal-rotation-combination test. A response surface equation was formed as follows: y = 384 - 7.245x1 + 11.705x2 + 15.475x3 + 14.039x1(2) + 41.831x2(2) - 79.49x3(2) - 35.375x1x2 - 3.375x1x3 - 106.625x2x3. The results showed that this method is simple, practical, and rapid enough for selecting fermentation media for Bt. In addition, the whole course of batch fermentation was also investigated.

The effects of pH, broth volume, initial sugar concentration, ratio of carbon to nitrogen and phosphorus, and the glucose feeding method on GSH production in a shaking flask were investigated. The results showed that the proper pH and broth content for GSH production were 6.0 and 60 ml broth per 500 ml flask, respectively. The initial glucose concentration distinctly affected the GSH production; the intracellular GSH content of yeast would decrease when the initial glucose concentration was beyond 12 g/L. A glucose feeding strategy with the purpose of controlling the specific growth rate at an expected value was developed and applied to a 12 hour fermentation with the total glucose concentration 26.2 g/L; the final cell concentration (DCW) and the intracellular GSH content could reach 8.78 g/L and 13.6 mg/g, respectively, while the total GSH in the broth was 119.4 mg/L and the yield of cell to glucose was 0.335 g/g.

Theophylline toxicity has been recognized since its introduction into clinical medicine. Clarithromycin is a new oral macrolide antibiotic with excellent antibacterial activity and rare adverse effect. Patients with upper respiratory infection are often treated with theophylline and clarithromycin concurrently. We report a case of acute renal failure due to acute rhabdomyolysis caused by the interaction of theophylline and clarithromycin. A 72-year-old man visited our hospital because of coughing and a sore throat continuing for 1 week. He was diagnosed as having the common cold with a bronchial asthmatic symptom and was prescribed 200 mg/day of sustained-release theophylline for the treatment of asthma for 7 days. One week later, he visited our hospital again. Radiographic study of the chest revealed mild interstitial pneumonia and 200 mg/day of sustained-release theophylline and 400 mg/day of clarithromycin were administrated concomitantly. Five days after the second visit, the patient was admitted to our hospital because of generalized twitching, muscular weakness, high fever and serious general condition. He experienced generalized muscular twitching and tremor. Blood urea nitrogen was 106.1 mg/dl, serum creatinine was 7.4 mg/dl, serum creatinine kinase (CK) was 36,000 IU/l (normal 15-130 IU/l), CK isozyme revealed the following ratio: BB 0%, MB 1% and MM 99%. He was diagnosed as having acute renal failure with rhabdomyolysis caused by the interaction of theophylline and clarithromycin. Hemodialysis therapy was started. After 5 weeks, his serum creatinine was markedly decreased. It is well-known that clarithromycin enhances the serum concentration of theophylline by inhibition of the cytochrome P450-dependent pathway in hepatocytes. Theophylline toxicity may be enhanced when clarithromycin is administrated concomitantly, especially to elderly patients with dehydration.
