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.

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.

Synovial sarcoma is an uncommon, highly malignant soft tissue tumor usually arising from the synovial lining of a joint, bursa and tendon sheath. Occurence in muscle fascia is extremely rare. We present a case of synovial sarcoma of the left calf muscle fascia, which was confirmed by microscopically sarcomatous growth of spindle cells and irregular small multiloculation. Above knee amputation was done.

To evaluate factors related to success rate of dacryocystorhinostomy, we retrospectively surveyed 131 eyes about age, sex, symptom duration, etiology, obstruction site, sac size, silicone tube insertion and surgeons learning curve. Patients age, sex, obstruction site and sac size were not related to surgical results, but longer duration of epiphora, trauma, silicone intubation and poor surgical skill had relationship with poor surgical results. Surgical skill was the most important factor in multiple logistic regression. We believe that surgical technique for making a mucosal flap with bone removal etc., was very important to surgical success.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

9.Silicone Tube Intubation in Acquired Nasolacrimal Duct Obstruction.
Journal of the Korean Ophthalmological Society 2000;41(2):327-331
45 eyes of 37 adult patients with nasolacrimal duct[NLD]obstruction were treated with silicone tube intubation. Silicone tube was removed between 1 and 12 months[mean 3.96 months]after surgery. After variable follow-up periods of 3 to 23 months[mean 6.82 months], 57.8%showed no epiphora, 28.9% showed intermittent epiphora and 13.3%showed ersistent epiphora. Complications were minimal and did not affect the outcome. We recommend that silicone intubation can be an alternative to dacryocystorhinostomy in selected adult patients. It is safe and less traumatic procedure with relatively high success rate in partial NLD obstruction and total obstruction with recent onset.
