Wistar rats were divided into three groups (n=5) according to age -30, 55 and 75 days- for histologic analysis of the length of the mesial and distal roots of the mandibular first molars. 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. 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 ]. 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. It served as the control. 2.2. Hits: 8200 8200. Pairing for matting was 1:1 for female/male. I. The learning process in slow-learning rats was accompanied mainly by passive emotional manifestations, whereas active reactions dominated at the stage of habit realization. The rats were divided into four groups (A, B, C and D) treated with graded doses (100, 200, 400 and 0 mg/kg respectively) of saponin extract of V. amygdalina over a period of 14 days. characteristics and morphology of Wistar strain albino rats exposed to arsenic toxicity.

Aged WISTAR Rat. The Wistar rat, Wistar Hannover (Wistar HAN) rat, and Wistar Unilever (WU) rat are outbred rat strains, while the Wistar Kyoto and Wistar Furth rats are inbred strains. The study was carried out on male rats of the GC (genetic catatonia), PM (pendulum-like movements), Wistar and WAG (Wistar Albino Glaxo) strains.

Albino rats earn their name because they don't have any pigment in their bodies, and that extends to their eyes, which don't have a color. 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).
