Inbred Strains of Mice: LP


Inbr (J) 125. Colour: white-bellied agouti with white patches Aw,s. Origin: Dunn 1928 from a chinchilla stock from Castle and some coat colour stocks from English fanciers. To Scott, to Dickie 1947, to J 1949. Maint. by J.


High emotionality (4/15) (Thompson, 1953). Susceptible to audiogenic seizures (1/11) (Fuller and Sjursen, 1967). Long life-span in conventional conditions (22/22 = 748 days in males, 22/22 = 799 days in females) (Storer, 1966). Overall tumour incidence 26% in males and 30% in females, with a wide range of tumour types, including mammary tumours (14% in females, 3% in males), lymphoma (1% in males, 8% in females), lung tumours (5% in males, 4% in females) and soft-tissue sarcomas (7% in males, 6% in females) (Smith et al. 1973). High plasma cholesterol at 12 and 24 weeks (1/8) (Weibust, 1973). High serum ceruloplasmin levels in females (5/27) and males (8/26) (Meier and MacPike, 1968). Low plasma cholinesterase activity in males (19/22) (Angel et al., 1967., 1967). Low hypoxanthene-guanine phosphoribosyl transferase in thalamus (7/7) (Suran, 1973). Low brain monoamine oxidase (6/7) and catechol-O-methyltransferase activity (7/7) (Tunnicliff et al., 1973., 1973). High mean heart rate adaptation (1/7) (Blizard and Welty, 1971). Large spinal cord (4/25) (Roderick et al., 1973., 1973). Small kidney/body weight ratio (17/21) (Schlager, 1968). Susceptible to skin ulceration by DMBA (cf. 13/22) (Thomas et al., 1973., 1973). Highly resistant to the induction of catalepsy by haloperidol (8/8) associated with midbrain dopamine D2 receptor density levels (Kanes et al, 1993)

Low retinal ganglion cell number (5/24) (Williams et al, 1996).

High lymphocyte phytohaemagglutinin response (9/43) (Heiniger et al., 1975., 1975). Poor immune response to ovomucoid, but good response to ovalbumin (cf. 6/12) (Vaz et al., 1971., 1971). Discriminator between `H' and `L' sheep erythrocytes (cf. 12/18) (McCarthy and Dutton, 1975).

Resistant to induction of diabetes mellitus by encephalomyocarditis virus (cf. 7/14) (Boucher et al., 1975., 1975).
