Background: The current study was conducted at the Department of Veterinary Pharmacology and Toxicology to assess impact Emblica officinalis on oxidative stress produced by sub-acute enrofloxacin exposure in albino rats. Methods: Albino rats weighing 200-300 gram were given orally through gavage needle blood samples taken via capillary tube 28th day experiment analysed using laboratory procedur...

Radioprotective effects of ethanolic extracts Gongronema latifolium leaf against radiation induced oxidative stress in Wistar albino Rats

Given the medicinal importance of avocado plant in alternative medicine,the present study aimed to effect phytochemical content P. americana leaf extract on hematological system albino rats. Albino rats were obtained andclustered into sixgroups,with five per groupsimultaneously assigned experimental and control. The group administered with varying doses prepared aqueous americanawithin period s...

The domestication process of the laboratory rat has been going on for several hundred generations in stable environmental conditions, which may have affected their physiological and behavioural functions, including their circadian system. Rats tested in our ethological experiments were laboratory-bred wild Norway rats (WWCPS), two strains of pigmented laboratory rats (Brown Norway and Long Evan...

Albino and hooded (or piebald) rats are one of the most frequently used laboratory animals for the past 150 years. Despite this fact, the origin of the albino mutation as well as the genetic basis of the hooded phenotype remained unclear. Recently, the albino mutation has been identified as the Arg299His missense mutation in the Tyrosinase gene and the hooded (H) locus has been mapped to the ∼4...

Background: Ageing is associated with the diminished function of various tissues in the body. The gonadal function decreases with the increase in age. Testes undergo atrophy resulting in shrinkage of seminiferous tubules due to reduced testosterone hormone level in elderly male. The process of spermatogenesis decreases in old age when compared to young adults. Today’s lifestyle makes an adult s...

This study investigated the toxicity of sodium fluoride on male reproductive hormones and ameliorative effects extract Phyllantus amarus adult albino rats. The consisted six equal groups five rats that were administered with over a period two weeks. result indicates possible hormone lipid profile probable capacity to ameliorate this toxicity.

Abstract Decreasing the salivary flow rate manifested by xerostomia occurs early during irradiation treatment. The duration of depressed function varies among patients. Various histopathological changes occur in glands. current study was performed to investigate and compare between possible anti-radiotherapeutic effect gamma rays-synthesized curcumin nanoparticles (Cur NPs), chitosan (Cs NPs). ...

STUDY OBJECTIVES Previous studies have demonstrated that albino but not pigmented rats show acute increases in REM sleep following light-to-dark transitions. Light and dark have also been shown to have direct effects on NREM sleep and wakefulness in albino rats. Little is known, however, about the direct light-dark effects on sleep patterns in pigmented animals. The purpose of the present study...
