Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

To elucidate the significance of the nesidiodysplasia of pancreas, histological re-evaluation and immunohistochemical studies for insulin, glucagon and somatostatin were done on 16 consecutive cases (5 premature babies, 2 stillborns, 5 infants and 3 adults) in which paraffin blocks of the pancreas were available. Only one infant was hypoglycemic. All 16 pancreases showed changes of nesidiodysplasia which appeared immunohistochemically to have isulin, glucagon and /or somatostatin. The histologic patterns of nesidiodysplasia included ductoendocrine proliferation, endocrine cell dysplasia, adenomatosis, septal islet, islket cell hypertrophy and islet hypertrophy. All the patterns of nesidiodysplasia except for the adenomatosis were seen in premature babies, infants, stillborns and adults with or without hypoglycemia. The adenomatosis was found only in the hypoglycemic infant. The result suggests that all patterns of nesidiodysplasia of other than the adenomatosis does not imply the pathologic basis of hypoglycemia.

Animal models are useful tools to study the molecular basis of schizophrenia pathophysiology and efficacy of potential therapeutic agents. Schizophrenia animal models can be subdivided into three classes ; drug-induced models, genetic models, and environmental models and each model is designed based on specific traits corresponding to the characteristic symptoms of human schizophrenia patients. Psychomotor agitation and sensitivity to psychotomimetic drugs are often thought to reflect positive symptoms. Social interaction deficits and affective impairments are known to correspond to negative symptoms. Also, cognitive symptoms have been linked to the working memory impairments, attention deficits and related cognitive deficits in animals. To analyze such components in quantifiable manners, various behavioral paradigms have been developed and utilized. Here, we overview these animal models, focusing on underlying rationales for their use in the context of schizophrenia research.

Serum Lipoperoxide levels were studied in 50 normal Korean and in the following patients; 26 patients with diabetes mellitus, 20 patients with hypertension, 14 patients with ischemic heart disease, 8 patients with cerebrovascular accident and 6 patients with nephrotic syndrome. The results obtained are summarized as follows; 1. In normal Korean, the average serum lipoperoxide level was 2.62+/-0.27 nmoles M.D. A./ml, with no difference by the sex. 2. In the cases with various disease which in supposed to be related to abnormal lipid metabolism, that is, diabetes mellitus, hypertension, ischemic heart disease, nephrotic syndrome, the serum lipoperoxide value showed statistically significant elevation compared to that of the normal control (p<0.01), but in the patients with cerebrovascular accident the elevation was not significant (p>0.05). 3. The serum lipoperoxide level was coarsely related with the serum concentration of cholesterol and total lipid, the correlation coefficient of which were 0.34 and 0.35 respectively (p<0.05).
