Experimental Allergic Encephalomyelitis (EAE) is an autoimmune demyelinating disease of the central nervous system that is widely accepted as an animal model for the human multiple sclerosis (MS). Since the EAE is also characterized by inflammation in the form of perivascular cuffing, we hypothesized that measuring the number of the inflammatory cells might correlate with the clinical signs and symptoms of the disease and could bring more understanding to the EAE different degrees of the inflammatory process. The model chosen to test this hypothesis was the EAE induced in Lewis rat. The 16 animals were administered Myelin Basic Protein (MBA) plus complete Freund's adjuvant and examined daily in a blind fashion for the signs of MS. Twenty-nine days later, animals were sacrificed and tissues from the spinal cord and were collected for Hematoxylene and Eosin histological studies using the image-Pro-Plus digital morphomtry technique. We concluded that EAE inflammation can be classified into mild, moderate and severs lesion based on the lymphocytes number which correlate with the clinical presentation of the diseased animal.

Susac's syndrome (SS) consists of the triad of encephalopathy, branch retinal artery occlusions (BRAO), and hearing loss. It usually affects women aged 20 to 40, but men are also affected, and the age range extends from 9 to 72 years. It tends to be unrecognized, even in major academic centers. The complete triad may not be present at the onset, which makes diagnosis more difficult. However, since this disorder is treatable, early diagnosis is important. The encephalopathy is usually associated with headaches, multifocal neurologic manifestations, and psychiatric features (particularly paranoia). MRI shows a white matter disturbance that is frequently confused with multiple sclerosis and acute disseminated encephalomyelitis. During the encephalopathy, the corpus callosum is always affected and shows central involvement--small to large "snowballs" and linear defects, "spokes." As the acute changes (microinfarcts) resolve, central callosal "holes" develop, a pathognomonic finding. The deep gray matter (70%) and leptomeninges (33%) also may be involved. Dilated fundus examination will reveal branch retinal artery occlusions. Fluorescein angiography may disclose pathognomonic staining of the arterioles proximal to the occlusions and of nonoccluded arterioles. The cochlear hearing loss, sometimes associated with vertigo, is usually bilateral, and deafness becomes a major disabling problem. Brain biopsies, anatomic observations, and responses to immunosuppressive therapy suggest that SS represents an autoimmune endotheliopathy in the microvasculature of the brain, retina, and cochlea. Treatment requires immunosuppression. High-dose corticosteroid therapy is the mainstay, but additional therapies such as intravenous immunoglobulin, mycophenolate mofetil, and cyclophosphamide are often necessary. Rituximab is the newest therapy to consider. Treatment should be prompt, aggressive, and sustained to avoid the dreaded residuals of dementia, deafness, and blindness.

Sesame oil was evaluated in the treatment of in C57BL/6 mice. It has profound anti-inflammatory activity and been traditionally used to treat inflammatory disorders. EAE was induced by immunization of 6-8 week old mice with MOG(35-55) with complete Freunds adjuvant. Therapy with sesame oil was started on day 3 before the immunization. Total Antioxidant Capacity (TAC) was assessed by Ferric Reducing-antioxidant Power (FRAP) method. Nitric Oxide (NO) production was also estimated by Griess reaction. For histological analysis, mice brain was harvested and sections were stained with Hematoxylin-Eosin. After daily intraperitoneal dosage the sesame oil significantly reduced the clinical symptoms in C57BL/6 mice with EAE. Also, treated mice displayed a significantly delayed disease onset compared with control mice. Sesame oil significantly increased TAC, but it's effect on serum nitrite production was not significant. Typical brain leukocyte infiltration was observed in control mice compared with treated mice. Present results suggest for the first time that sesame oil therapy may be effective in the prevention of symptomatic EAE. This resistance to encephalomyelitis may be associated with inhibition of oxidative stress.

In this study, effect of ethanol extract of Saffron (Crocus sativus L.) in the treatment of Experimental Autoimmune Encephalomyelitis (EAE) in C57BL/6 mice was evaluated. EAE was induced by immunization of 8 week old mice with MOG(35-55) with complete Freunds adjuvant. Therapy with saffron was started on day the immunization. Total Antioxidant Capacity (TAC) was assessed by Ferric Reducing-Antioxidant Power (FRAP) method. Nitric oxide (NO) production was also estimated by Griess reaction. For histological analysis, mice brain was harvested and sections were stained with Hematoxylin-Eosin. After daily oral dosage the saffron significantly reduced the clinical symptoms in C57BL/6 mice with EAE. Also, treated mice displayed a delayed disease onset compared with control mice. TAC production was significantly elevated in saffron treated mice. Effect of saffron on serum NO production was not significant. Typical spinal cord leukocyte infiltration was observed in control mice compared with saffron treated mice. These results suggest for the first time that saffron is effective in the prevention of symptomatic EAE by inhibition of oxidative stress and leukocyte infiltration to CNS and may be potentially useful for the treatment of Multiple Sclerosis (MS).

Interleukin-9 (IL-9) is a multifunctional cytokine involved in protective immunity or immunopathology depending on the microenvironment and specific disease settings. Our early study determined that IL-9 and Th9 cells participate in and promote the progression of experimental autoimmune myasthenia gravis (EAMG). The data from this study showed that exogenous recombinant rat IL-9 (rrIL-9) acted as an IL-9 receptor antagonist, reduced the incidence of EAMG in rats, alleviated the severity of the disease, and reduced the anti-acetylcholine receptor (AChR) IgG antibody levels by altering the Th-subset distribution. These data suggest that administration of rrIL-9 may provide a novel therapeutic strategy against MG or related autoimmune diseases.
