Experimental evaluation of the viscoelasticity of porcine vitreous.

This study aims to estimate the material properties of the porcine vitreous while testing it in close to its natural physiological conditions. Eighteen porcine eyes were tested within 48 h post-mortem. A custom-built computer-controlled test rig was designed to support, load and monitor the behaviour of eye globes while being subjected to dynamic rotation cycles mimicking saccade eye movement.

Numerical study of the effect of head and eye movement on progression of retinal detachment.

Rhegmatogenous retinal detachment (RD) is a sight threatening condition. In this type of RD a break in the retina allows retrohyaloid fluid to enter the subretinal space. The prognosis concerning the patients' visual acuity is better if the RD has not progressed to the macula.

Oltipraz treatment in experimental schistosomiasis mansoni:VII. Effect of high dose oral therapy on alkaline phosphatase level in livers of infected mice.

Biochemical estimation of alkaline phosphatase (AP) in livers of mice experimentally infected with the Egyptian strain of S. mansoni before and after oltipraz treatment was carried out. The drug was given in a single oral dose of 500 mg/kg body weight.

The prophylactic and curative effect of oltipraz in experimental schistosomiasis mansoni in mice.

Effect of oltipraz on immature and mature forms of Schistosoma mansoni in mice experimentally infected with the Egyptian strain of the worms was assessed. The drug was administered to different groups of mice in a single oral dose of 750 mg/kg body weight 2 hours before infection, 7 days and 15 days after infection and in a single oral dose of 500 mg/kg body weight 30 days and 45 days after infection. Oltipraz was found to be active in reducing the number of worms significantly only when administered in a higher dosage 2 hours before infection and 7 days after infection.

Oltipraz treatment in experimental schistosomiasis mansoni: VI. Effect of high dose oral therapy on alkaline phosphatase level in the intestines of infected mice.

Extraction of alkaline phosphatase (AP) from the tissues of small intestines of mice experimentally infected with the Egyptian strain of S. mansoni before and after oltipraz treatment was carried out. The drug was given in a single oral dose of 500 mg/kg body weight.
