LITTER SIZES IN INBRED STRAINS OF RATS (RATTUS NORVEGICUS)
International Journal of Immunogenetics, 1979SummaryThe average litter sizes and reproductive performance of twenty‐five inbred strains of rats, maintained in a conventional colony in Pittsburgh, and twenty‐six inbred strains, maintained in a barrier facility at the National Institutes of Health, were calculated from data collected for periods of 3 and 10 years, respectively.

Heterotopic and orthotopic liver transplants in inbred rat strains
Microsurgery, 1979AbstractThe functioning and survival of orthotopic liver allotransplants in toto were compared with heterotopic partial and whole allotransplants in inbred rats. In contrast to the rapid and aggressive rejection of the heterotopic allografts, the orthotopic whole‐liver allografts survived for prolonged periods.

Strain differences in inbred rats: influence of strain and diet on haematological traits
Laboratory Animals, 19835 inbred strains of rats maintained on 3 commercial pelleted diets were investigated for differences in haematological traits on the 154th day of age. Number, size and haemoglobin content of the erythrocytes were shown to be strongly influenced by strain and diet.

Variations in catechol-O-methyltransferase activity in inbred strains of rats
Neuropharmacology, 1977Abstract Catechol-O-methyltransferase (COMT) activity was measured in nine strains of rats aged 9 to 11 weeks. Hepatic COMT activity levels in Sprague-Dawley and Fischer 344 animals varied from 48% to 66% of those in livers of the other strains studied.

Efficient collection and cryopreservation of embryos in F344 strain inbred rats
Cryobiology, 2013In rats, it is now possible to produce genetically engineered strains, not only as transgenic animals but also using gene knockout techniques. Reproductive technologies have been used as indispensable tools to produce and maintain these novel valuable strains.

The response of three inbred strains of rat to the carcinogen 1,2-dimethylhydrazine
Pathology, 1981Rats of 3 inbred strains (DA, HS and AS2) were dosed with 1,2-dimethylhydrazine 2HCl (DMH) or saline by gavage weekly for 10 wk. DA and HS rats showed little overt toxic reaction but all AS2 rats died following DMH doses of 30 mg/kg. However, at 10 mg/kg 60% of AS2 rats survived the 30 wk experiment. All DA rats developed a high yield of adenocarcinoma

Differences in Kindling Development in Seven Outbred and Inbred Rat Strains
Experimental Neurology, 1998The kindling phenomenon, i.e., the progressive development of focal and secondarily generalized seizures upon repeated electrical stimulation of a limbic brain region, occurs in various species, but with marked differences in kindling rate between species and also within the same species. In rats, differences in kindling rates have been reported within

Correlative Analysis of Ethanol‐Related Phenotypes in Rat Inbred Strains
Alcoholism: Clinical and Experimental Research, 1984As a summary presentation of the ethanol‐related traits in the rat inbred strains, the responses to ethanol for various traits of the eight strains were analyzed. The intercorrelations among the means of the strains were computed and the interrelationships among the strain con‐elations were determined further by partial correlation and factor analysis.

Two Inbred Rat Strains That Differ Substantially in Hip Fragility
Calcified Tissue International, 2003One approach to identifying the genetic influences on skeletal phenotypes involves the creation and genetic mapping of a population of the second filial (F2) offspring derived from a cross of two inbred strains of rodents. The two inbred strains should be chosen based upon a large difference in the phenotype of interest, e.g., bone fragility.
