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.

We successfully closed the isolated patent ductusarteriosus(PDA) in 2 female patients using the Rashkind Double-Disc Occlusion system. nonsurgical closure of PDA usin plug was introduced by Porstmann in 1968 through transfemoral artery catheter and using umbrella by Rashkind in 1977 througth venous site. There has been continued improvement and simplification of the equipment as well as in the implantation technique. Nowaday, a multicenter study was conducted to test the safety and effectiveness of this interventioal method in States. Successful closure rate was high but some problems were reported such as embolization, abnormal deployment and residual shunt. Residual shunt was visualized by aortography in our both cases immediately after intervention but continuous murmur could not be heard in both cases. Oxygen step-up disappeared immediately after occluder implantation in both cases. Complete occlusion was expected with thrombus in near future.

We report a case of plexiform neurofibroma developed under the overlying speckled lentiginous nevus, which occurred in a 20 year-old man. In this patient and his family no other signs of von Recklinghausens disease were found. Discussion is focussed on the fact that both plexiform neurofibroma and speckled lentigmous nevus, which represent a defect in the neural crest, occurred in the same area of the skin.

A case of intraventricular meningioma(within Rt. Lateral ventricle) accompanied by intraventricular hematoma and subarachnoid hemorrhage is reported. Intraventricular meningioma fantastic and characteristic from the view points of its location is a rare condition;moreover hemorrhage into meningioma in general is exceedingly rare and presents with very unusual clinical pictures. Timely correct diagnosis and surgery aimed at evacuation of hematoma and total excision of the meningioma is essential, if satisfactory therapeutic results are to be obtained. Literatures concerned were reviewed.
