摘　　要：BACKGROUND： Myasthenia gravis （MG） is an autoimmune disease which mainly affects neuromuscular junctions. The ages, modified Osserman classification and clinical manifestation and humoral immunol function of MG with and without thymic abnormality are different. OBJECTIVE： To explore the clinical manifestation and humoral immuno-function of MG with abnormal and normal thymus gland. DESIGN ： Contrast observation SETTTNG ： Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University PARTZCZPANTS ： A total of 49 inpatients with MG were selected from the Third Affiliated Hospital of Sun Yat-sen University from March 2000 to August 2005. All the patients had typical clinical manifestation of MG and positive neostigmine test. All the patients knew and agreed the laboratory examinations. There were 22 males and 27 females of 2-69 years old. Chest MRI or CT scan were performed to reveal thymus gland abnormality. According to whether there was tumor in superior mediastinum, all patients were divided into 2 groups, abnormal and normal groups. Normal thymus gland group （n=30） contained 16 males and 14 females of 6-43 years old. Abnormal thymus gland group （n=19） contained 6 male and 13 female of 2-69 years old, METHODS： ① All patients were questioned about initial symptoms. Meanwhile, main clinical manifestations were recorded at hospital admission. ② 7180A automatic biochemical analyzer and automatic microplate reader were used in detecting seroimmunity index. The levels of C3, C4, IgG, IgA, IgM and CH50 in blood serum were analyzed by nephelometry. ③ Clinical classification is based on modified Osserman classification. The patients with MG were divided into six types： I （Ocular myasthenia）, Ⅱ a （Mild generalized myasthenia）, Ⅱb （Moderately severe generalized myasthenia）, Ⅲ （Acute fulminating myasthenia）, Ⅳ（Late se- vere myasthenia）. MAZN OUTCOME MEASURES： ① Differences of initial symptoms and clinical manifestation of two group patients. �BACKGROUND： Myasthenia gravis （MG） is an autoimmune disease which mainly affects neuromuscular junctions.
