Relationship of Adrenaline Administration to Increased Blood Sugar Levels in Male Rattus norvegicus Rats

Quantity Discrimination in Domestic Rats, Rattus norvegicus

Quantity discrimination is a basic form of numerical competence where an animal distinguishes which of two amounts is greater in size. Whilst quantity discrimination in rats has been investigated via training paradigms, rats' natural quantity discrimination abilities without explicit training for a desired response have not been explored. This study investigated domestic rats' ability to perfor...

A survey on helminthic infection in mice (Mus musculus) and rats (Rattus norvegicus and Rattus rattus) in Kermanshah, Iran

Parasitic infections of rodents can compromise scientific research as well as the health of the animals and humans. Based on previous studies, infection rate of parasitic helminths is different in various regions of Iran. The current survey was aimed to determine endoparasitic helminths infection in 138 trapped rodents of Kermanshah county, Iran. Mice and rats were trapped using metal snares fr...

Role of male scent glands in improving poison bait acceptance in female rats, Rattus norvegicus.

The poison (Zn3P2) bait mixed with preputial gland and cheek gland extract was highly effective as compared to poison bait mixed without the scent gland extract, in increasing the food consumption and mortality rate in rats. Among these two scent glands, preputial gland extract was more effective than cheek gland extract in increasing the bait acceptance. The scent gland extract mixed with pois...

Effect of Alkaloids of Achyranthes aspera Linn. on fertility in male albino rats (Rattus norvegicus)

Effects of microcurrent stimulation on Hyaline cartilage repair in immature male rats (Rattus norvegicus)

BACKGROUND In this study, we investigate the effects of microcurrent stimulation on the repair process of xiphoid cartilage in 45-days-old rats. METHODS Twenty male rats were divided into a control group and a treated group. A 3-mm defect was then created with a punch in anesthetized animals. In the treated group, animals were submitted to daily applications of a biphasic square pulse microga...
