Strain differences of the light-dark preference in inbred rats [PDF]

open access: possibleBehavior Genetics, 1989
The present study examined strain differences in the light-dark preference among four strains of rats. The test was done in the home-cage situation under 12L:12D cycles. Data from four strains were compared: BN/Kyo, BDIX/Nem, Wistar/Nu, and F344/NSlc.

Phylogenetics of rat inbred strains

Mammalian Genome, 2003
Laboratory rats (Rattus norvegicus) have played animportant role in biomedical research for over 100years with more than 200 strains bred as physiologi-cal models of human disease (Lindsey 1979; Steenet al. 1999; Kwitek-Black and Jacob 2001). Unlikemouse inbred strains, little is known about rela-tionships among rat strains (Festing 1979).

Reagin synthesis in inbred strains of rats

Journal of Allergy and Clinical Immunology, 1973
Reaginic antibody synthesis after intraperitoneal immunization with ovalbumin in aluminium hydroxide gel (Al(OH)3) has been evaluated in BN, F344 and ACI inbred strains of rats and compared to that in outbred Wistar rats. Regardless of the dose of antigen employed (0.1 mg, 0.01 mg, 0.001 mg), BN inbred and Wistar outbred rats produced comparable ...

Spontaneous Thymoma in an Inbred Strain of Rat 2

JNCI: Journal of the National Cancer Institute, 1977
Thymomas that appear with high frequency in inbred WAB rats living into old age were examined. The spontaneous thymomas described were discrete, encapsulated bodies composed of lymphocytes and epithelial cells, with a predominance of lymphocytes. The rat neoplasms resembled the human thymomas, and their rate of incidence in older animals may suggest ...

Energy balance in an inbred strain of rats: Comparison with the wistar strain

Physiology & Behavior, 1994
Food intake and body weight gain were examined in two groups of male rats (7 weeks): an inbred strain, Dark Agouti (DA, n = 12) and a noninbred strain, Wistar (n = 13). The animals were allowed to select their diet from separate sources of the three macronutrients protein, fat, and carbohydrate.

Cholesterol Response in Inbred Strains of Rats, Rattus norvegicus [PDF]

open access: possibleThe Journal of Nutrition, 1981
A hypercholesterolemic diet fed to rats revealed significant interstrain differences in plasma cholesterol levels. Hyperresponding and hyporesponding strains could be distinguished from normoresponding strains within 3 weeks. The increase in plasma cholesterol level was more than 300 mg/100 ml in the hyperresponding strains BN/Cpb, SD/Cpb and WE/Z and ...

Behavioral and neurochemical differences in an inbred strain of rats

Physiology & Behavior, 1990
The spontaneous motility of 75 Sprague-Dawley rats obtained from an inbred strain was found to vary widely. To test the hypothesis that heterogeneity in motility is accompanied by heterogeneity in neurochemical and vegetative function variables, the median motility score was used to divide the animals into high and low motility groups.

Variation in haematological parameters among inbred strains of rat

Laboratory Animals, 1981
Haematological determinations were carried out on 7 inbred strains of rats using a standardized procedure. Significant genetic variation was found for many of the parameters although none of the strains had values which could be termed pathological. Measurements also varied significantly from day to day. Factorial analysis of variance is shown to be a

Inbred Strains of Rats

Behavior Genetics, 1979
The first listing of inbred strains of rats was by Billingham and Silvers (1959). This is the fifth listing and has been substantially revised, although it is heavily dependent on previous listings (Festing and Staats, 1973). In contrast with previous listings, an attempt has been made to cite the original reference for any given strain characteristic.
