strain_behavior Can not be triggered into paradoxical sleep by dark pulse stimulation (ie. turning off the lights), incontrast with LEW (Leung et al, 1992). Higher precentage of paradoxical sleep than LEW (Rosenberg et al 1987). Low preference for ethanol and low capability to develop acute tolerance to ethanol hypnosis (York et al, 1994). Behavioural performance declined less rapidly with aging than in strain F344 (Spangler et al, 1994). Somewhat vicious. Poor performance in an active avoidance learning task (4/4), but good reference memory (VanLuijtelaar et al 1988) 1004

strain_immunology Resistant to induction of experimental allergic encephalomyelitis (1/7) (Gasser et al 1975,McFarlin et al 1975a,b). However, resistance can be modulated by endogenous corticosteroids (Peers et al, 1995). Resistant to induction of autologous immune compex glomerulonephritis (Strenglein et al 1975). Like strain MAXX, but in contrast to 17 other strains BN is susceptible tothe development of mercury-induced autoimmunity to renal basement membranes with the development of membraneous glomerulonephritis (Henry et al 1988). Susceptible to theautoimmune effects of mercury showing a decrease of peripheral RT6.2(+) T lymphocytes compared with strain LEW (Kosuda et al 1994), but no release of hydrogen peroxide in peritoneal polymorphonuclear leukocytes and macrophages in contrast with LEW (Contrino et al,1992). Susceptible to the development of autoimmunity to skin-injected HgCl2 , in contrast toLEW (Warfvinge and Larsson, 1994). Develop a T-helper 2 cell-mediated autoimmune syndrome following treatment with mercuric chloride, gold or D-penicillamine which may be associated with the response of mast cells (Oliveira et al, 1995) Moderately sensitive to the development of experimental glomerulonephritis following injection of nephritogenic antigen from bovine renal basement membrane (Naito et al, 1991) Develops severe experimental allergic encephalomyelitis when immunised with rat spinal cord and carbonyl iron adjuvent (Levine and Sowinski 1975). Linington et al (1986) induced experimental allergic neuritis using T-cells and bovine P2 (a peripheral nerve myelin protein). Resistant to the induction of Haymann nephritis (Badalamenti et al 1987). High IgE response to Japanese Cedarpollen antigen (1/7): may be a useful model for studying physiological and pathological changes in the nose after pollen challenge (Imaoka et al, 1993). Resident macrophages (ramified microglea)of the central nervous system are constitutively major histocompatibility complex class-II positive, in contrast with LEW (Sedgwick et al, 1993). Following lethal irradiation and re-constitution with syngeneic bone marrow and given cyclosporin A for several weeks LEW rats will develop cyclosporin-induced autoimmunity after withdrawal of the cyclosporin. The condition resembles graft-versus host disease in terms of acute dermatitis and chronic scleroderma. However, BN rats do not develop this disease (Wodzig et al, 1993). Resistant to the induction of experimental autoimmune uveoretinitis and endotoxin-induced uveitis which appears to be associated with the production of tumour necrosis factor (TNF) by retinal Muller glia and retinal pigmented epithelium. Strain LEW is susceptible (Dekozak et al, 1994). Susceptible to the induction of proteinuria following treatment with the monoclonal antibody 5-6-1, like LEW and outbred Wistar, but unlike resistant outbred Sprague-Dawley rats which were also resistant to glomerular damage (Gollner et al, 1995).Low antibody response to phytohaemagglutinin, concanavalin A and streptococcal group A carbohydrate (Koch 1976, Stankus and Leslie 1976, Williams et al 1973). Good (1/5) antibody response to a synthetic 20 amino acid peptide derived from the alpha helical region of the RT1-D-u beta chain (Murphy et al, 1994). 1004

strain_life_disease Endocardial disease 7% at an average age of 31 months (Boorman et al 1973). Tumours of epithelium 28% in males, 2% in females. Ureter tumours 20% in females, 6% in males. Estimated median life-span more than 24 months in males and more than 25 months in females (Boorman and Hollander 1974). Median lifespan 29 months in males (n=74) and 31 months in females (n=236). Most common neoplastic lesions in males were urinary bladder carcinoma 35%, pancreas islet adenoma 15%,pituitary adenoma 14%, lymphoreticular sarcoma 14%, adrenal cortex adeneoma 12%, medullarythyroid carcinoma 9%, adrenal pheochromocytoma 8%. Four other types of tumours were observed. In females: pituitary adenoma 26%, ureter carcinoma 22%, adrenal cortical adenoma19%, cervix sarcoma 15%, mammary gland fibroadenoma 11%, islet adenoma 11%. Twelve other tumour types were observed (Burek and Hollander 1975a). The chance of death from metastases increased with age in females, but reaches a peak at 25-30 months in males (Burek and Hollander 1975b). The cervical and vaginal tumours have been studied in more detail by Burek et al (1975a), and further details of an aging colony are given by Hollander (1976) and Burek and Hollander (1977). Vaginal and cervical tumours, mostly sarcomas but also seven squamous-cell carcinomas and four leiomyomas, were seen in 20% of animals that died naturally (Burek et al 1976). High incidence (31%) of hydronephrosis reported in 2-month-old BN/Bi (Cohen et al 1970), but little seen by Gray et al (1982) before 30 months,after which the disease progressed slowly. A high incidence was observed at all ages by Spangleret al (1994). 1004
