Zinc sulphate and boric acid ophthalmic preparations, containing benzalkonium chloride as preservative, have been investigated against gram-negative and positive bacteria. Viability of bacteria was found after 7 days, although it was completely suppressed after 24 hours of inoculation. Zinc sulphate generally increases the antimicrobial activity of benzalkonium chloride, whereas boric acid ...

Dopamine 3-0-sulphate (3-0-hydrosulphato-4-hydroxyphenethylamine) was isolated from newly ecdysed cockroaches, Periplaneta americana (L.), and its structure established by chemical and physical techniques and by synthesis. Relatively high concentrations (about 1 pmol/g wet wt.) of dopamine 3-0-sulphate exist in the newly ecdysed insect, and these concentrations decrease sharply as sclerotizatio...

Exo-polysaccharides like dextran produced by Weissella sp. have a wide range of applications in the food, pharmaceutical and other industries. This biopolymer and its derivatives like iron dextran, clinical dextran are rapidly emerging as a new and industrially important products. Dextran a polymer of glucose is produced using sucrose rich media with nitrogen source. It also requires efficient ...

13 LOW DOSE MAGNESIUM SULPHATE REGIME FOR ECLAMPSIA Bangal V., Kwatra A., Raghav S., Jadhav S. Abstract Preeclampsia is one of the commonest medical complications seen during pregnancy. It contributes significantly to maternal and perinatal morbidity and mortality. Dr.J.A.Pritchard in 1955, introduced magnesium sulphate for control of convulsions in eclampsia and is used worldwide. Considering ...

By M. C. BERENBAUM, K. J. CHILD, B. DAVIS, HELEN M. SHARPE AND E. G. ToMIci T HE ORAL TREATMENT of hypochromic anemia with inorganic salts of iron occasionally results in gastrointestinal distress, and massive doses produce necrosis of the gastric mucosa and liver ( Forbes, 1947; Smith, 1952; Swift, Cefalu and Rubell, 1952; Luongo and Bjornson, 1954) . A recent survey ( Hoppe, Marcelli and Tain...

1 Urine was collected over 24 h from 40 patients with advanced malignant disease who had received a known four-hourly oral dose of either diamorphine or morphine in an elixir or of diamorphine by injection for at least 3 days. 2 Samples were assayed for total urinary morphine (free and conjugated) by gas-liquid chromatography. 3 The percentage of the administered dose recovered as morphine was:...

The Bacteroides fragilis ATCC strain was grown in a synthetic media with contrasting redox potential (Eh) levels [reduced (-60 mV) or oxidised (+100 mV)] and their adhesion capacity to extracellular matrix components was evaluated. The strain was capable of adhering to laminin, fibronectin, fibronectin + heparan sulphate and heparan sulphate. A stronger adherence to laminin after growing the st...

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...

1. New preparations of reduced carboxymethylated /3-ovomucin (S-carboxymethylf,-ovomucin) were homogeneous by sedimentation analysis, analytical sedimentation to equilibrium in CsCI gradients, and disc electrophoresis in sodium dodecyl sulphate. 2. Degradation of S-carboxymethyl-f/-ovomucin with either CNBr or trypsin indicated the presence of a subunit (approx. mol.wt. 112300). 3. Electron mic...
