In this study we tested whether the critical anatomical substrate for retinal direction selectivity is altered in albino mammals. We used dual immunostaining for GABA and choline acetyltransferase and quantitatively analyzed the number of double-labelled starburst amacrine cells in wild-type and albino rats. In albino rats, the percentage of ON-amacrine cells with high GABA content was signific...

The water extract of poochendurappattai was screened for antitumour activity at the doss of 5mg, 10mg, 20mg and 50 mg/kg body weight in rats against methylcholanthrene induced fibrosarcoma. There was 63% regression in the tumour weight at the doses of 10mg and 20 mg/kg body weight. This antitumour activity may be due to compounds like royaleanones since royaleanones are known to possess antican...

The present study evaluates the histological effects of oral sodium benzoate on liver of albino rats. The study comprises of 4 groups of albino rats. Each group consists of 10 albino rats. Of these, first group was given 400mg/kg body weight sodium benzoate orally in distilled water, second group was given 800mg/kg body weight sodium benzoate in distilled water, and the third group was given 12...

The aim of research study was undertaken to investigate the effect of different schedules of oral administration of tulsi( Ocimum sanctum)leaf on serum calcium and serum phosphate activities of male albino rats. Ocimum sanctum (1g/kg body weight) administration for 60 days in male albino rats on biochemical parameters weighing, between 100-150g obtained from the disease free stock of the animal...

Albino mice and rats have elevated dark-adapted thresholds compared to normally pigmented animals. The absolute dark-adapted incremental threshold for black mice is about 1.5 log units lower than the threshold for albino mice when measured by single-unit recordings from the superior colliculus. Cell counts from the outer nuclear layer in albino mice are not significantly different from those in...

Objective: To evaluate the effect of different preparations fluoride gels on salivary pH albino rats. Material and Methods: This experimental study consisted 40 Albino rats randomly divided into four equal groups. Group A was control group received no intervention. Experimental B a topical application 0.2% sodium gel. C stannous gel 0.4%. D APF (1.23% acidulated phosphate gel). The were applied...

OBJECTIVE To determine the morphological changes induced by mobile phone radiation in the testis of Wistar albino rats. STUDY DESIGN Cohort study. PLACE AND DURATION OF STUDY Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia, from April 2007 to June 2008. METHODOLOGY Forty male Wistar albino rats were divided in three groups. First group of eight se...

Dried powder of leaf extract of common Indian plant Moringa Oleifera of Moringaceae family was tested experimentally in albino rats in our laboratory for its antifertility activity. Cant per cent abortifacient activity was found when administered orally in aqueous solution at dose of 175 mg/kg body weight daily to Charles foster strain albino rats from days 5-10 post mated.

Background: Diuretics increase urine flow and sodium excretion are used to maintain the volume composition of body fluids in a variety clinical situations Objectives: To evaluate diuretic activity alcoholic (AERMI) extract roots Mangifera indica albino rats. Methods: 5 groups Albino rats were by using metabolic cages. The group I serves as normal control received vehicle, II Furosemide (10 mg/K...

We compared in albino and pigmented rats the early effect of unilateral labyrinthectomy (UL) on the concentrations of monoamines (norepinephrine, dopamine, serotonin) and their respective metabolites--3-methoxy,4-hydroxyphenylglycol (MHPG), 3,4-dihydroxy-phenylacetic acid (DOPAC), and 5-hydroxyindoleacetic acid (5HIAA)--in medial vestibular nuclei (MVN), locus coeruleus, raphe dorsalis, and coc...
