Biochemical, histological, and neuro-physiological effects of long-term aluminum chloride exposure in rats.

This study aimed to evaluate the effect of daily sublethal doses of aluminum (Al) on hematological, physiological, biochemical, and behavioral changes in male albino Wistar rats. In addition, Al tissue accumulation and histopathological changes in the cerebral cortex, liver, and kidney were examined. The rats were randomly separated into three groups.

Neurological alterations induced by formulated imidacloprid toxicity in Japanese quails.

Agrochemical risk assessment that takes into account only pesticide active ingredients without the spray adjuvants will miss important toxicity outcomes detrimental to non-target species including birds. In the present study toxicity of imidacloprid (IMI) pesticide was evaluated individually and in a mixture with polyethylene glycol (PEG-600) as adjuvant against Japanese quails. Oral intubation was used to obtain concentration-mortality data.

The potent effects of ginseng root extract and memantine on cognitive dysfunction in male albino rats.

The study determined the maximum intraperitoneal (ip) scopolamine dose inducing memory impairment in rats (2 mg/kg) compared to 0.5 or 1 mg/kg dose. The effect reflected by significant increase from normal in the latency time required for rats to find the hidden platform in water maze task and acetylcholinesterase (AChE) activities in cortex, hippocampus and striatum.

Zinc sulphate and vitamin E alleviate reproductive toxicity caused by aluminium sulphate in male albino rats.

This study was designed to investigate the reproductive toxicity of aluminium sulphate and the therapeutic effects of administration of zinc sulphate and vitamin E individually or in combination against the toxic effect caused by aluminium (Al) in male albino rats. The animals were divided into five groups: group 1 received distilled water and served as control; group 2 received only aluminium sulphate (50 mg/kg body weight (b.w.

Identification of a genetic marker associated with the resistance to Schistosoma mansoni infection using random amplified polymorphic DNA analysis.

In schistosomiasis, the host/parasite interaction remains not completely understood. Many questions related to the susceptibility of snails to infection by respective trematode still remain unanswered. The control of schistosomiasis requires a good understanding of the host/parasite association.

Biological and biochemical studies on Biomphalaria alexandrina snails, treated with low concentrations of certain molluscicides (synthetic and of plant origin).

The effect of low concentrations of different synthetic and natural mollusciciding agents may introduce to fresh water environment on reproduction and biochemical aspects of Biomphalaria alexandrina was studied. Different mollusciciding agents (copper sulphate, Bayluscide, Uccmaluscide, Agave filifera & A. attenuate) inhibited egg production, induced marked increased the percent of abnormal laid eggs and induced marked reduction in their hatchability.
