Abstract: Abstract A sensitive and simple spectrophotometric method is developed for the determination of catecholamine drugs namely; methyldopa, dopamine and adrenaline in pure and pharmaceutical preparations. The method is based on the oxidation of the cited drugs with iron(III) in acidic medium and the liberated iron(II) reacts with 1,10-phenanthroline. The ferroin complex is colorimetrically measured at 510 nm against reagent blank. Beer's law was valid over the concentration ranges of 0.1-2.8, 0.1-2.0, and 0.2-6.0μg/ml and the molar absorptivities are 1.851×105, 1.544×105 and 4.331×104 l.mol-1cm-1 for methyldopa, dopamine and adrenaline respectively. The common excipients and additives did not interfere in their determinations. The proposed method was successfully applied to the assay of the above drugs in various dosage forms.

Abstract: New complexes salts of A2[VOCl5] and A3[TiCl6],where A = , X = H or CH2Ph, were prepared by treatment of above organic salts with metal chloride in (3:1) or (2:1) molar ratio. The new complex salts were characterized by microelemental analysis, conductivity measurements, spectroscopic data (IR and U.V/Visible) as well as the magnetic measurements. These studies confirm that the complex salts are 2:1 electrolytes and the VO (V) or Ti(III) in the anionic moiety of the complex salts achieve octahedral environment.

Abstract: ABSTRACT A spectrophotometric method for the assay of micro amounts of paracetamol has been developed. The method is based on the reaction of p–aminophenol which results from the acid hydrolysis of paracetamol, with nitrite ion to form the corresponding diazonium salt followed by coupling reaction in an alkaline medium with phloroacetophenone to form a stable and soluble orange azo dye. The intensity of absorbance for the resulting azo dye is measured at 472 nm and Beer’s law is obeyed in the concentration range of 10–180 g of paracetamol in a final volume of 25 ml, with a molar absorptivity of 2.16104 l.mol-1.cm-1, a relative error of -0.64 to +1.64% and a relative standard deviation of 0.4 to 1.24 %, depending on the concentration level of paracetamol. The method has been successfully applied to the assay of paracetamol in various pharmaceutical preparations.

Abstract: ABSTRACT A series of Schiff bases N-Arylidene benzylamie (1-6) have been prepared, and through 1,3-anionic cycloaddition under strong basic conditions were added to benzoquinone to afford the fused new pyrrolidines (7-12).

Abstract: ABSTRACT The research was concerned with isolation of alkaline phosphatase (ALP) from the aqueous extract of Aloe Vera using gel filtration technique. It was shown that, using gel filtration chromatography on Sephadex G-100, the solution of the proteinous precipitate produced by ammonium sulphate saturation, contained two proteinous peaks. The two peaks possessed a variable activity of alkaline phosphatase, where maximum specific activity was obtained in the first peak with higher molecular weight which showed (28) folds of purification. Furthermore, the comparative molecular weight of the partially purified alkaline phosphatase (first proteinous peak) using gel filtration was found to be (147353) Dalton. The research was also concerned with finding the optimum conditions of alkaline phosphatase. Maximum activity was obtained using sodium carbonate- bicarbonate buffer (100 mM) at pH ( 9.7 ), (50ºC) and (30 mM) of di-sodium phenyl phosphate as a substrate. Using linweaver-Burk plot, it was found that the Vmax and Km have the values of (185.18 enzyme unit/dl of proteinous solution) and (3.9mM) respectively. The results also predicted that the activity of alkaline phosphatase decreased gradually and reached 76% and 50% from the original value when stored at 4ºC and at room temperature (33-40ºC) respectively for 30 days.

Abstract: ABSTRACT Nitric oxide (NO) has been recently recognized as a major mediator of resistance against fungus infection. Therefore, we investigated the effect of the pharmacological compound (Na nitroprusside) (SNP) as the NO donor on the in vitro growth of Candida albicans . The results of present study revealed that Na nitroprusside (NO donor) inhibited the C. albicans growth in a concentration - dependent manner, maximal inhibition concentration was observed in (SNP) with concentration (17.5mg/ml from growth media), there was complete inhibition of C. albicans growth occurs in comparison with the control without (SNP) .On other hand the addition (SNP) at concentration ranged from )10- 15mg/ml from growth media ( capable of restricting the growth of C. albicans . In contrast, no C. albicans growth inhibition occurs when (SNP) addition at concentration ranged from (0.625- 7.5mg/ml from growth media ) . The data suggest that the pharmacological compound (SNP) may be useful in the development of new therapeutic agents for treatment of Candida infections.

Abstract: Abstract The nervous system of Ophiotaenia europea appeared distinct after reaction with the enzymatic technique (AchE) as the sites appeared as brown in color . All other parts appeared as yellow white which made the detection of the nervous system fairly easy . The nervous system of the worm consists of two cerebral ganglia connected together by transverse cerebral commissure forming the cerebral ring which is in turn connected to small rostellar ring , which is the first to be discovered in this species . The rostellar ring is formed from the connection of 4 rostellar ganglia .From each cerebral ganglion six pairs of trunks arises two thin pairs lateral and one distinct pairs ventro- lateral lie between the lateral and the margin . From rostellar ganglia about 18 very slender nerves arise and run parallel to other nerve cords , they become as network in each of the mature segment .the nerves trunks both stout and slender are connected each other by a number of transverse commissures which vary with respect to the different proglottides . This worm is unique in distribution of the post- lateral ganglia at the connection of the transverse commissures and along the lateral and medial nerve trunks .Furthermore the ganglia present at the connection of transverse commissure are smaller than those present at lateral and medial nerve trunks. A positive reaction was also observed in the gonad anlagen and in the reproductive organs.
