Hepatolenticular degeneration or Wilson's disease is a familiar disorder Characterized by hepatic cirrhosis, progressive degeneration of central nervous system and Kayser-Fleischer ring in the cornea. The author recently experienced a case of typical Wilson's disease which showed characteristic signs such as Kayser-Fleisher ring, dysarthria, dysphagia, slurring speach, gait spastic, choreicform movement and Liver cirrhosis, and the literatures relating to this disease were briefly reviewed.

For the purpose of observing ultrastructure of the epicuticle of Echinorhynchus gadi, the present electron microscopical studies had been made. Also the histochemical methods of Morwy, Bauer, Smith, Lison, Taft, and those of lead and uranyl acetate had been used in order to see the distribution of glycogen, mucopolysaccharides, lipid and nucleic acid in the cuticle of Echinorhynchus gadi. The results obtained by the above studies were as follows: Glycogen, mucopolysaccharides were found in the outermost, middle and inner layers, especially abundant in the middle layer of the cuticle. Lipid was found in the middle and inner layer, and it was found abundantly around the lacunal canal in the cuticle. Nucleic acid was found around the lacunal canal in the middle layer, and also distributed in the cell nucleus of inner layer in the cuticle. Electron microscopically, the cuticle of Echinorhynchus gadi had three outer layers, being outermost, middle and inner ones. The outermost layer was medium electron dense, composed with plasmalemma and filaments. The middle layer was homogeneous one which was electron pale. The inner layer, which was electron dense, consisted of felt layer and radial layer. The electron dense glycogen, lipid granules were distributed in radial layer.

A 57 year old male, complaining of exophthalmos, disturbance of ocular motility and visual acuity in the right eye, was admitted under the disgnosis of orbital tumor. The tumor was removed by Kronlein procedure and verified as glioma microscopically. The following seven months period of postoperative observations revealed degenerative changes in the retina, atrophy of the optic nerve and enophthalmos in the affected side but no signs of recurrence.

The authors have recently experienced 2 cases of ocular texoplasmosis which had poor vision. These cases were presumptive diagnosis of ocular toxoplasmosis by typical ocular lesion and hemmagglutinin test for toxoplasmosis. In addition to clinical observations, a brief review of literature has been described.

After Toxoplasma gondii (RH strain) was inoculated into the intra peritoneum of the gpc-mouse, the changes in their orbits and brains were studied. The results were as following: 1) The mouses expired 4-6 days after this inoculation, apparantly due to their sensitivity to the toxoplasma organism. 2) The examinations of both eyes showed mild chronic non-specific inflammatory cell infiltration in ciliary boby, iris, choroid and retina, revealing early mild chronic endophthalmitis. 3) The examination of their brain showed edema and focal degenerative change with chronic inflammatory cell infiltration. 4) There was no difference between the changes in the right and left eyes.

Neurofibromatosis(von Reckling hausen's disease) is a congenital heredofamilial disorderresulting from dysplasia of neuroectodermal and mesodermal tissues. It is characterized by developmental anormaly, pigmentary skin lesions and multiple tumors derived from the Schwannian cells of the peripheral and sensory nerve. The authors have experienced two cases of Neurofibromatosis. which is clinically diagnosed. and confirmed by histopathological examination. It was reviewed clinically with the literature.

Xeroderma Pigmentosum is a hereditary disorder characterized sunlight sensitivity multiple cutaneous malignancies, usually basal and squamous cell carcinoma and frequent ocular complication. The auther has presented recently treated one case of limbal squamous cell carcinoma associated with Xeroderma Pigmentosum in 15 years old male. It was reviewed clinically with the literature.

The authors recently experienced a case of typical Gronblad-strandberg's syndrome which showed characteristic signs such as degenerative changes of the skin and angioid streaks without known familial disposition of this disease, and the literatures relating to this disease were briefly reviewed.

This study was designed to examine the effects of two antidepressant drugs on the expression of c-fos mRNA in cultured embryonic rat hippocampal neurons. The drugs used were imipramine and amitriptyline. On the fourth day of culture, hippocampal neurons were treated with variable concentrations of each drug. Competitive RT-PCR(Reverse Transcriptase-PCR) analysis was used to quantify the c-fos mRNA expression induced by each drug. Experimental results showed that acute and direct treatment with imipramine and amitriptyline with relatively low concentrations(imipramine < or =10micrometer, amitriptyline < or =10micrometer) had no inductive effect on the expression of c-fos mRNA in the rat hippocampal neurons. However, after treatment with relatively high concentrations(imipramine > or =100micrometer, amitriptyline > or =100micrometer) c-fos mRNA was not detected. These findings suggest the followings. Firstly, the action mechanisms of these drugs on the hippocampal neurons might not be mediated by c-fos but by other immediate-early genes(IEGs). Secondly, their actions may be mediated indirectly via other areas of the brain. Thirdly, the expression of c-fos might be inhibited by high concentrations of these drugs, or the high concentrations could induce cell death. Finally, though cell death remains to be confirmed, the inhibition of c-fos induction or cell death could play a role in the cognitive impairments known to be adverse effects of some antidepressants. This study is believed to be a first step toward understanding the mechanisms of learning and memory. Further studies are needed to investigate the expression of various IEGs and changes in the hippocampal neurons of rat resulting from chronic treatment with antidepressant drugs.

OBJECTIVE: The purpose of this study was to investigate physical and ultrasonographic (US) imaging findings in pain-free shoulders of high school baseball players. METHOD: Physical examination including range of motion (ROM) and several pain provocative tests and US examination on both shoulders in forty-one high school baseball players were performed. The findings of these examinations were classified according to the dominance of shoulders and position of the players and described. RESULTS: Neer, Jobe, Hawkins test, and acromioclavicular tenderness were positive in 33.3%, 4.8%, 28.6%, and 38.3% respectively. Dominant shoulders had larger ROM of external rotation and internal rotation than non-dominant shoulders (p <0.05). Dominant shoulders of pitchers group had larger ROM of external rotation and smaller ROM of internal rotation than those of non-pitchers group (p <0.05). Dominant supraspinatus tendons of pitchers group were thicker than those of non-pitchers group (p <0.05). CONCLUSION: About one third of pain-free shoulders of baseball players showed positive in pain provocative tests. There were several differences in shoulder ROM and ultrasonographic thickness of supraspinatus tendon according to the dominance of shoulders and position of players.
