AS.

Inbr.F60+.

Colour: Albino.

Genet: c.

Origin: University of Otago from Wistar rats imported from England in 1930. May be subline of GH, with which it is histocompatible (Heslop and Phelan 1973).

Characteristics

Hypertensive, though not to such an extent as GH (Heslop and Phelan 1973). Glomerular filtration rate and renal plasma flow studied by Hackbarth et al (1981), and haematology and its relation to diet studied by Hackbarth et al (1983). Susceptible to the development of experimetnal allergic encephalomyelitis (Hughes and Stedronska 1973). Susceptible to induction of autologous immune complex glomerulonephritis associated with the major histocompatibility complex (Stenglein et al 1975). Low antibody response to phytohaemagglutinin; not linked to MHC (Koch 1976). Long pentobarbitone sleeping time (2/10 males, 1/10 females, Vieregge et al 1987) Good reproductive performance.
