Two kinds of copper-pure and 70% dilute alloy suspension were introduced into the vitreous of albino rabbits, and electron microscopical observation was carried out on the retinal tissue after several periods from 1 day up to 60 days. Major changes are as follows: 1. Early response of rabbit retina with pure copper foreign body exhibited severe and diffuse destruction with much deposition of particles mainly in nerve fiber layer. The influence of 70% copper alloy to the retinal tissues tended to demonstrate mild, localized and delayed in occurrence. 2. In the nerve fiber layer where the tissue disintegration took place Muller cell demonstrated the features of mitosis and proliferation. Including this rare incidence, it is possible to conclude that Muller cell proliferation occur in any part of the retina if the condition allows. 3. Cytoid bodies mainly consisting with glycogen aggregates within the Miiller cell processes in nerve fiber layer was one of prominent pictures in early stage. 4. Muller cells took an important role in reparative process replacing the destructive portion of the retinal cells with the extension of the same cells beyond the external limiting membrane toward the choroid. 5. At the late stage, the Muller cells contained abundant filaments replacing the reduced number of smooth surfaced endoplasmic reticulum and other organells. That implicats the enhancement of supportive mechanism at the occasion of the disintegration of retinal tissue prolonged. 6. A relatively early sign was active phagocytosis of retinal pigment epithelial cells engulfing the reminiscent fragment of ouer pigment of visual cells.

Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

To predict the mydriatic status of the cataract patients preoperatively, we performed maximal mydriasis test with stepwise instillations of 1% tropicamide and 2.5% phenylephrine or 10% phenylephrine to the out-patients who was scheduled to have cataract operation. Among 210 eyes of 113 patients, the pupillary size of 167 eyes was dilated to 8mm or more and the other 43 eyes were insufficiently dilated to less than 8mm diameter. In the insufficiently dilated group, we have observed the presumable causes of insufficient mydriasis as follows: posterior synechiae, diabetic autonomic pupillopathy, age-related miosis and unknown. By this test, we could predict the mydriatic status of the cataract patient preoperatively and could prepare the appropriate operative method and equipment effectively.

In order to evaluate the distributions of the immunoglobulins in the pterygial tissues, surgically excised pterygia from 18 patients were examined according to PAP staining method to detect the presence of various Ig classes with the control of 5 cases of normal conjunctiva. The PAP staining on the pterygial tissues revealed that the incidence of the positive reactions in 88.7% of IgG, 27.8% of IgA, and 88% of IgE which indicated the noticeable increase in compare with the normal conjunctival tissues. The increased number of IgG, IgA, and IgE in pterygial tissues appeared statistically significant than those of normal conjunctiva(p<0.05). From the evaluation of results, it was attributed that the occurrence of pterygium may result with the immunological processes of inflammatory component. The increase of the IgE in pterygial tissue might also be contributable for the Type I hypersensitivity for the pathogenesis of pterygium.

Venous thrombosis is uncommon in young individuals. Hypereosinophilia is a rare cause of thrombosis that usually involves the heart and small vessels like retinal vessels. We report a case of massive deep vein thrombosis that developed in a young patient with hypereosinophilia who was successfully treated with continuous local infusion of urokinase.

Sixty patients anesthetized with nitrous oxide-oxygen-halothane, who received pancuronium for the maintenance of muscular relaxation were divided into three group of twenty each. Ath the end of anesthesia, the patients of Group l received in 1.0mg atropine travenously and neostigmine 2.0mg: those in Group ll glycopyrrolate 0.4mg and neostigmine 2.0mg. and those in Group lll atropine 0.5mg, glycopyrrolate 0.2mg and neostigmine 2.0mg. After that the changes in heart rate, arrhythmsia, blood pressure and oropharyngeal secretions were observed and evaluated. The results are as follows: 1) The safety and effectiveness of all groups in antagonizing the muscarinic actions of neostigmine were demonstrated. 2) Glycopyrrolate produced a significantly smaller change in heart rate than atropine. 3) There were no significant difference in the indicence of severe tachycardia in all groups respectively. 4) Glycopyrrolate is superior to atropine in the antisalivary action. 5) There were no more advantages in combined use of atropine and glycopyrrolate than that of atropine or glycopyrrolate separotely.

Retinal dysplasia is an important disease in the study of retinal development. The differential diagnosis of retinal dysplasia from retinoblastoma is very difficult to make clinically, but histologically the diagnosis is made by the structure of rosettes. The authors experimentally gave trauma to retina of rats and produced retinal dysplasia; we observed under electron microscope the incomplete rosette of retinal dysplasia and the complete rosette appearing in retinoblastoma. We concluded that both rosettes are formed in developing retina with environmental or hereditary defects and did a comparative study of their characteristic fine structures.
