Persistence of rat parvovirus in athymic rats
Archives of Virology, 1989Euthymic (SD or outbred rnu/+) and athymic (rnu/rnu) rats were inoculated oronasally or intraperitoneally with the RV-Y strain of rat virus when they were 2 days or 4 weeks old. Clinical signs of infection in athymic infants were similar to those in euthymic infants, but significantly more athymic infants died.

Transmission of Rat Virus in Milk of Rats
Journal of Infectious Diseases, 1974blood, mammary glands, and milk removed from the stomachs of sucklings all had infectivity titers of approximately 10-3-10-4/0.1 ml when tested in rat embryo tissue cultures. Rat virus continued to be recoverable for a number of days after the appearance of circulating (HAI) antibodies.

Journal of Comparative Pathology, 1992
We report three tumours arising in the brain stem or adjacent cranial nerves of the Alderly Park rat. Light microscopy with special stains, immunocytochemistry and electron microscopy supported the conclusion that both neuronal and myoid differentiation occurred in all neoplasms.

The pinealectomy technique consists of the surgical removal of the superficial pineal gland. This procedure allows the ablation of circulating indoles produced by this gland. Withdrawal of systemic melatonin, a pineal hormone, affects animal circadian rhythms and induces several physiological changes that are the subject of many investigations. In this

Abstract To assess the contribution of the condyle to the growth of the mandible, forty-two Holtzman albino rats weighing between 40–50 g, were bilaterally condylectomized and at maturity compared anatomically and radiographicalry with 10 shamoperated and 27 control animals. From standardized lateral radiographs, the incisor overjet and molar overjet

Digestion, 2009
Four months of sigmoid colon intrinsic denervation of young male Wistar rats resulted in typical megacolon. Average 46.0% denervation of the Auerbach plexus was obtained by serosal application of benzalkonium chloride (0.2% v/v). Denervation was assessed by ganglion cell counts in a 480-nm extension of the treated segment.

Scandinavian Journal of Urology and Nephrology, 1979
A high incidence of spontaneous, non-acute, age-dependent prostatitis was observed in the lateral prostate of Copenhagen rats and Wistar rats. The lumen of infected acini was filled with polymorphonuclear leucocytes, shed epithelial cells and cell residues. Epithelial cells lining such acini showed degenerative changes. Lymphocytes and macrophages were

Veterinary Clinics of North America: Exotic Animal Practice, 2010
The past decade has seen an increase in the number of rodents being kept as pets and subsequently in the number of rodent owners seeking veterinary services. The common rat, (Rattus norvegicus) has become increasingly popular, particularly as novel varieties have been introduced to the pet market.

Rat-Rat Hybridoma Formation and Rat Monoclonal Antibodies
1987The first model of monoclonal antibody-secreting hybridomas, developed by Kohler and Milstein (1), was a mouse system. It can be considered eminently successful, most likely because of its efficiency and extreme stability. If it is so successful, why develop another rodent model? There are, at least, three main reasons.

Basic mechanisms of the rat ERG were reinvestigated with contemporary methods of recording and photic stimulation via an optic fiber system connected with a contact lens. Flash stimulation and background illuminance were performed with photometrically defined light stimuli.
