ampicillin, every 12 h) for 7 or 21 days (7 and 5 ponies, respectively), procaine penicillin G intramuscularly (12 mg/kg = 12,000 IU/kg, every 24 h) for 7 days (7 ponies), or ampicillin sodium intravenously (equivalent to 15 mg/kg ampicillin, every 8 h) for 1 day (5 ponies)...
The resulting monomeric peaks were pooled and concentrated to 12 mg/ml (PBP4) or 15 mg/ml (PBP5). Crystallization PBP4 Purified PBP4 crystallized in 40 mm KH2PO4, pH 3.25, 16% PEG 8000, 20% glycerol, 10 mm TCEP (vapor diffusion). PBP4-acylated complexes with benzylpenicillin, ...
After thirty minutes white crystals of 2-benzyl4-ethoxymethylene - 5(4) - oxazolone hydrobromide precipitated from the solution and were removed by filtration. The crystals were washed with dioxane and absolute ether and immediately dried in a vacuum desiccator. 400 mg. of the crystals were re...
Two weeks earlier, she had received amoxicillin 875mg/clavulanic acid 125mg twice daily for 10 days for bronchitis. Her regular medications included aspirin 100 mg/day, which she had received for at least 4 years [ indication not stated ]. Four months after the onset of symptoms, ...
Serum rifamycin concentrations at the time of the reaction were available for only one patient (no 6) who was on rifampin 450 mg daily; after 5 months of treatment, a serum concentration 2路5 hours after the dose was 22路07 g/mL, considerably higher than the usual range of values in ...
五倍子粗萃物劑量為128 mg/ml併用Penicilllin G 3.36 unit/ml即可抑制細菌生長.而在殺菌效力評估試驗(time kill assay),其劑量為1024 mg/ml時,在24小時內,即具有99 %的殺菌效果,因此進行管柱層析法(column chromatography)並配合活性追蹤分離出五個有效成分,再經結構鑑定與抑菌活性評估,發現GR5(1, 2, 3, ...
The enzyme hydrolysed penicillin V and synthetic analogues such as 2-nitro-5-(phenoxyacetarnido)-benzoic acid (NTPOAB). The corresponding kinetic parameters were KM = 3 mM and V max = 92 mol min-1 mg-1 for penicillin V; KM = 15.3 mM and V max = 14.5 mol. min-1 mg-1 for NIPO...
Synergism was studied using a combination of 1/2 × MIC of the beta-lactam antibiotic and 8 mg/l of tobramycin. The bactericidal activity did not exceed 10 +3 cfu/ml at 5 hours for any single compound. After 5 h all three beta-lactam antibiotics in combination with tobramycin resulted ...
specific PA activity at glucose depletion increased from 0.09 to 0.16 U mg~-1 dry cell weight(DCM),whereas volumetric PA activity decreased in a Monod-type behavior from 0.25 to o U m~-1.The PA activity increased 1.5-3.3-fold when prolonging the culture for 10-25 h after growth ...
