Strain: AA

Symbol: AA
Strain: AA
Full Name: Alko, Alcohol
RGD ID: 70410
Citation ID: RRID:RGD_70410
Ontology ID: RS:0000007
Also Known As: Alko-accepting
Type: inbred
Available Source: Not Available
Origination: Research Laboratories of the State Alcohol Monopoly (Alko), Helsinki, Finland
Description: Wistar rats were outbred and selected for breeding animals that differ in their alcohol consumption. Marked difference between the strains and sex was visible by the eighth generation. After puberty the animals were isolated and given 10% alcohol as drink for 10 days, after which they had access to water and alcohol for 4 weeks. The quantity of fluid intake was measured daily. Fluid intake of animals varied greatly in animals consuming the same amount of alcohol per unit body weight, so alcohol intake was used as a phenotypic measure.
Inbred Generations: F72-77
Last Known Status: Unknown

strain_characteristics Animals consumed the same amount of alcohol when offered a choice between water and alcohol (5-10% by volume). 70283
strain_phys_biochem AA have a two fold higher level of brain histamine as compared to alcohol avoiding ANA rats in both hypothalamus and septum. AA rats have a higher density of histamine-ir-figres. No difference was observed in the expression level of L-histidine decarboxylase (HDC), the enzyme that catalyses histamine synthesis. AA rats have a lower expression of H1 receptor mRNA as compared to ANA rats. 68895
