In this research, the kinetics study of one isoenzyme of Maltase, which purified from the urine of diabetes mellitus patients was studied. Maltase isoenzyme was obeyed Michaelis- Mentons eqution. The optimum concentration of their substrate Maltose was (300 mmol/dm3). Their Km values was determined. Isoenzyme of Maltase have shown an optimum pH at (6.5) for phosphate buffer and (7.5) for tri ethanol amine. Maltase isoenzyme obeyed Arrhenius eqution up to 25°C and their Ea and Q10 constant were determined, after measuring the activity of Maltase of urine of diabetes mellitus patients. Isoenzyme of Maltase was separated and purified in previous study from urine of patients of diabetes mellitus

An experiment was conducted in randomized complete block design with four replicates to study the effect of spraying nitrogen fertilizer as a urea with concentration 0 , 10 , 20 , 30 mg/liter on the characters of cotton Koker 310 at summer season 2007 in experiment station of cotton research unit in mosul technical institute , all the agricultural practices were done for the end of season where study the plant height , number of nodes to the first fruit branch , number of vegetative branches , number of fruiting branches , number of bolls /plant , boll weight , seed index , lint index , lint percentage and seed cotton yield kg/h . Spraying urea fertilizer in concentration 20 mg/liter significantly exceeded from control in plant height , number of fruiting branches , number of bolls/plant , boll weight and seed cotton yield kg/h in percent 63.72 , 24.49 , 43.92 , 8.92 , 42.59% respectively while seed index significantly differed from control treatment in other used concentrations . Spraying urea fertilizer reflected significantly linear regression correlation to increase seed index and degrease lint percentage in addition to positive significant correlation for seed cotton yield with plant height , number of vegetative branches , number of fruiting branches , number of bolls /plant , boll weight and seed index .
