They Must Have Pink Eyes to Be Considered "Albino" There are many all-white rats in the world, but unless they have pink eyes, they're not true albinos. The Sprague Dawley rat and Long-Evans rat were developed from Wistar rats. These rats have no melanin in the body, including the eye. Experimental Animals Fifty (50) albino rats of the Wistar strain aged 10 - 12 weeks and weighing 70 - Ocular Dimensions of Laboratory Animals and Humans Rodents Commonly, albino rats are used in general toxicity studies with ophthalmological examinations. In conclusion, the saponin component of V. amygdalina did not produce adverse effects on the reproductive potentials of the rats and can therefore be used to boost reproduction in male wistar rats. The result obtained indicate that the ethanol extract of Desmodium Velutinum stem possess hepatoprotective activity on the fatty liver of albino wistar rat fed with fat from cows brain. Thirty-five 8-week-old female and male Wistar albino rats were obtained from the Medipol Medical Research Center (MEDITAM, Istanbul, Turkey). Type: Outbred rat.

Their peepers get their pink hue because the light is bouncing off the blood vessels in their eyes. The estrous cycle consists of four stages known as proestrus, estrus, metestrus and diestrus. With regularly handling and lots of space they quickly become very tame and friendly. Rats have a prevalence within biomedical research second only to humans and they share 90% of the genome with humans. 2 . There was no significant strain effect on the main characteristics of AK development including kindling rates, the number of stimulations . I. Toxicological investigation of sbl on white rat (Wistar albino): The potential toxicity of the SBL on white rat (Wistar albino) was investigated by supplementing the feed given to 30 rats with varying concentrations of SBL for a period of two weeks. morphological characteristics, there were dose dependent decrease in rudimentary tail, bent tail, curved mid-piece and bent mid-piece. Albinism of laboratory rodents: The majority of laboratory rodents are albinos, due to a common mutation in tyrosinase gene in all albino laboratory rat strains [ 18] and in at least some of the albino mouse strains [ 19 ].

Wistar rats encompass a number of rat substrains that have been derived from a common lineage over the past 50+ years. Wistar rats are albino and outbred, originating from the Wistar Institute (PA, USA). On gross examination no thymus could be found in the mediastina of young animals, whereas in older mutants lobules of fatty tissue mimicked the appearance of the thymus of the wild-type strain. Group 2 and 3 received 0.5 ml of a concoction of Andrographis paniculata [] 2. In vitro.

The renal arteries . been studied in rats and chicks (Elegbede, 1998). The WISTAR rat is an outbred stock, used in all fields of medical and biological research. Forty Total of 106 three-dimensional endocasts of the intrarenal arteries of kidney that were prepared using standard injection-corrosion techniques were examined. Sixty healthy wistar albino rats were taken for the study. The rats were acclimatized for two weeks before the experiment started. morphological characteristics, there were dose dependent decrease in rudimentary tail, bent tail, curved mid-piece and bent mid-piece. Group 1 served as control and received distilled water. The twenty-five (25) male albino rats were divided into five (5) groups of five (5) rats per group. Objective: Statins have been widely used for the treatment of hypercholesterolemia, and recent studies have shown that these drugs also affect bone metabolism. Twenty - four female albino Wistar rats weighing between 179 g - 257 g were randomly divided into four groups of six animals per group.

It is an ideal model for many oncology and infectious disease applications. The learning process in slow-learning rats was accompanied mainly by passive emotional manifestations, whereas active reactions dominated at the stage of habit realization. Gender differences and subsequent deterioration of retinal cell layers is an interesting topic, especially because there is no published work concerning it. Sixteen, 23-24-day old weanling litter male Wistar albino rats (50-60), were procured from the Animal House of the Department of Biochemistry, University of Port Harcourt, Port Harcourt, Nigeria. In the Wistar Albino Glaxo Rats from Rijswijk (WAG/Rij) model of absence epilepsy that display spontaneously-acquired seizures [57,58], enhanced CaV3.1 and CaV3.3 currents have been observed in lateral geniculate and centrolateral TCR neurons [59]. Methods: Our study was carried out on 16 rats (240 10 g) which were randomly divided into 2 groups of 8 animals. The gross anatomy and morphometry of the kidney and renal arteries were studied in the strains of laboratory rat: Sprague-Dawley (Sp) and Wistar (W) rats. After 14 days oral administration of the saponin extract, the rats . Since the PM rat strain is outbred, rats of the outbred Wistar strain were used as a control, while for the inbred GC, the inbred WAG were used. 2014 [cited 2022june23];2(10):2686-2690. After 2 weeks of acclimatization period, rats divided into nine groups of six animals in each group and experimental duration for 40 days.

We studied the effect of pinealectomy on the parameters of 4-day infradian biorhythms in mature male Wistar rats. Tissues were fixed in 10% buffered formalin (pH = 7.2) and embedded in paraffin. A single renal artery was observed in 100% of the cases. Wistar albino rats were divided into a control group (those kept away from the noise due to a generator set), groups 1 (exposed to varied, 85 - 105 db levels of loud noise from a generator) and groups 2 (exposed to less, 40 - 55 db . The rats had excellent health. This study was therefore carried out to investigate the effects of the chromatographic fractions of S. mombin on the semen characteristics and morphology of male Wistar rats exposed to sodium arsenite (SA).
