Antibacterial property of goat milk lactoperoxidase.

The goat milk lactoperoxidase was purified using CM sephadex C-50 and sephadex G 100. The purity of protein was confirmed by SDS-PAGE. The purified protein was found to have antibacterial action against most of the disease causing bacteria.

Echo-planar imaging relaxometry to measure the viscosity of a model meal.

A method for measuring noninvasively the viscosity of a polysaccharide model meal using the known relationship between relaxation times and polysaccharide concentration in solution in vitro is presented. The aim is to develop a method for monitoring digesta viscosity in vivo, using EPI to capture the motion of the gastrointestinal lumen. The transverse relaxation rate T-12 of locust bean gum solutions was calibrated against the zero-shear viscosity at 37 degreesC.

II. Steady-State Rheological Investigations.

Depletion flocculation of an alkane-in-water emulsion has previously been found to induce phase separation and, above certain polymer and oil concentrations, a delay period prior to the onset of creaming. In this paper the steady-state viscometry of an emulsion of 1-bromohexadecane-in-water has been investigated in the presence of hydroxyethylcellulose as the depletion flocculant. We have sought to characterize the flow behavior of this emulsion system and determine the characteristic rheology during the delay period.

I. Creaming Behavior.

We report an experimental investigation on the creaming behavior of flocculated, polydisperse, oil-in-water emulsions. Flocculation is by addition of a depletion flocculant, the polymer hydroxyethylcellulose (HEC), at a range of concentrations. The creaming behavior is dependent on the oil volume fraction and polymer concentration.

Effect of biochanin - a against filarial vector.

A successful attempt of using sodium salt of a water- insoluble larvicide, as an alternative to the use of solutions of such larvicides in acetone and water, for the larvicidal studies is made, in the present study biochanin - A an isoflavone isolated from the flowers of Dalbergia sissoides (grah) when assessed for larvicidal study as its sodium salt on the fourth instar larvae of Culex quinquefasciatus (Sa) showed significant larvicidal activity [LC 50 308.238ppm, LC90 1889.926 ppm].

Ventral screw fixation of odontoid fracture, using single fluoroscope.

This paper is a detailed description of an improvised operative technique used by us, for ventral screw fixation in a case of type II odontoid fracture.

Dietary fiber and lipid peroxidation: effect of dietary fiber on levels of lipids and lipid peroxides in high fat diet.

Effect of feeding coconut and blackgram fiber isolated as neutral detergent fiber (NDF) on the levels of lipids and lipid peroxides was studied in rats given a high fat diet. Concentration of cholesterol, free falty acid and phospholipids showed significant decrease in the serum, liver aorta and intestine of coconut and blackgram fiber groups. Concentration of malondialdehyde (MDA) and conjugated dienes was significantly decreased in liver and intestine of both fiber groups, while hydroperoxides showed significant increase in liver and heart of both the fiber groups.

Visual evoked response in macular diseases.

Visual evoked responses (VER) were recorded in 10 patients with unilateral maculopathy. VER latency and amplitude were compared between the affected and unaffected eyes. Evaluation of results reveals that in macular disease with fluid accumulation (Central Serous Retinopathy and Traumatic Macular Oedema) the VER showed amplitude reduction depending on reduced visual acuity with no significant change in latency, whereas, in disease with degeneration of retinal layers, (Degenerative Maculopathy) latency was markedly increased signifying associated conduction defect.

Maternal mortality--an avoidable catastrophe.

A retrospective study of work-load and maternal mortality over the past 10 years (1976-1985) at the Women's Hospital, Doha was conducted. 68,540 mothers delivered out of which 4,296 through C-section. The maternal mortality rate, although accounts for 17.
