Experimental autoimmune encephalomyelitis (EAE) is a T cell-mediated autoimmune disease of the CNS and an animal model for the human demyelinating disease, multiple sclerosis. In the Lewis rat, myelin basic protein (MBP)-CFA-induced EAE is an acute monophasic disease from which animals recover fully, do not relapse, and develop a robust long-term resistance to further active reinduction of disease. In this paper, we report that rats recovering from MBP-CFA-induced EAE have significantly increased serum levels of reactive nitrogen intermediates indicative of increased NO production. These levels remain elevated after the recovery period and increase even further early after a rechallenge with MBP-CFA, and all animals are totally refractory to a second episode of disease. Oral treatment of rats with N-methyl-l -arginine acetate (l -NMA), beginning at peak disease on day 11 postimmunization, results in significant prolongation of disease and an alteration in the presentation of clinical symptoms from that of solely hind limb paresis/paralysis to severe fore limb involvement as well. Treatment of fully recovered rats with l -NMA 24 h before a rechallenge with MBP-CFA leads to decreased serum reactive nitrogen intermediate levels and results in a second episode of EAE in 100% of animals. Furthermore, l -NMA treatment of fully recovered rats in the absence of a rechallenge immunization leads to spontaneous relapse of disease.

A 4-year-old female Maltese (case 1), a 9-year-old castrated male shih tzu (case 2) and 2-year-old female Pomeranian (case 3) presented with neurological signs, such as head tilt, ataxia, circling and paresis. The three cases were tentatively diagnosed as having meningoencephalitis of unknown etiology based on computed tomography scan and cerebrospinal fluid analysis. All patients were managed with cyclosporine plus prednisolone therapy. The survival times of the three patients were 170, 70 and 21 days, respectively. After the cases died, we performed necropsy and histopathological examination for definitive diagnosis. Based on the necropsy, histopathological and immunohistochemical examinations, cases 1, 2 and 3 were definitely diagnosed as having necrotizing meningoencephalitis, necrotizing leukoencephalitis and granulomatous meningoencephalitis, respectively. This case report demonstrated the clinical findings, brain CT characteristics and histopathological and immunohistochemical features of NME, NLE and GME in dogs and discussed the reason for the relatively short survival times under cyclosporine plus prednisolone therapy.
