Lactate were completely converted to acetate, 0.4 mmol CH_3CHOHCOO~- were consumed as 1 mmol SO_2 were reduced and the system was stable when SO_2 feed rate was 14.063mmol·h~(-1).
The results showed that ①the acute LD50 of norfloxacin hydrochloride, norfloxacin nicrotinic and norfloxation lactate was 5529.7mg/kg, 5847.9mg/kg and 9120.1mg/kg by oral administration, 450.7mg/kg, 568.9mg/kg and 574.1mg/kg by intraperitoneal injection, determined by karber method.
②the inhibition zones by norfloxacin hydrochloride, norfloxacin nicotinic and norfloxacin lactate were 30.7±1.4mm, 31.4±1.2mm and 30.5±1.1mm to Salmonella C79-13, were 31.5±1.5mm, 32.0±1.3mm and 31.2±1.7mm to E. coli O2 respectively.
The linear range of detection of the sensor is 0 04 to 2 1 μmol·L -1 with sensitivity of 137 nA/μmol·L -1 lactate. The lifetime of the sensor is 19 days.
Methods The changes in cardiac function, myocardial ATP and lactate were observed in the isolated low-temperature preserved Wistar rat hearts preserved in UW, HTK solutions and UW, HTK with addition of trimetazidine (10-6 mol/L) at 4 ℃for 8 h.
Studies on Developmental Genetics of Isozymes in Goldfish (Carassius auratus L.) Ⅱ. Analysis of Lactate Dehydrogenase Isozymes During Embryogensis of Goldfish
In the presence of microelements, the development of populations of bifidobacteria was associated with a more pronounced accumulation of metabolic products (acetate, lactate, and ethanol).
(1) In the present report a simple type of bacterial mill is described. The chief advantages of this apparatus are high percentage of disintegration, short duration of grinding and repeatability of results. The apparatus is essentially composed of a ground glass cylinder made from suitable hard glass tubing, which is filled with ice and rotates mechanically in horizontal position in a closely fitting trough of hard porcelain. (Fig. 1 and 2). It allows with the help of an abrasive, such as glass powder, to b...
(1)The cardiac disturbances of hypothermic dog under ether anaesthesia showed the following types:ventricular fibrillation,asystole or asystolic fibrillation.The mean terminal temperature of animals was 16.9±1.14℃.There was no correlation between the type of cardiac disturbance and the value of the terminal temperature. (2)The hypothermic ventricular fibrillation of dog could be completely prevented by systemic administration of hypertonic glucose solution,whereas hypertonic sucrose solution was ineffective...
Coronary blood flow was measured by N_2O desaturation method in anesthetized dogs. Coronary sinus catheterization was made under fluoroscopic guidance. Myocardial consumptions of oxygen, glucose, lactic acid and pyruvic acid were calculated from the differences between arterial and coronary sinus blood concentrations. This study was designed in paired experiments, and the results were analyzed by t test of individual comparisons. Normal values (mean±s.d.) of 9 dogs were: 143±17 and 8±3 mm Hg for arterial an...
