This study was investigated to compare the staining resistance of soft denture liners. Specimens wee made of Coe-soft. Coe-Comfort, Soft-liner, Visco-gel, and were stored in 1% methyleneblue solution for 24 hours. The amounts of color change before and after treatment with mono-poly and thermocycling were measured by colorimeter(TC-6FX, Tokyo Denshoku Co. Ltd, Japan) for evaluation of staining resistance. The following conclusions were drawn from this study. 1. The staining resistance of Visco-gel was increased, but there was no changer of staining resistance in Coe-soft, Coe-comfort, and Soft-liner after treatment with monopoly. 2. The staining resistance of the Coe-comfort was the least in all soft denture liners. 3. The staining resistance of Visco-gel and Soft-liner were decreased after thermocycling.

Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

This study was performed to investigate the effects of impression method and design of the retainer on the stress of abutment tooth in distal extension RPD. Three different types of direct retainer such as Akers clasp. RPI clasp, and wrought wire clasp were designed . Stress on the abutment tooth was measured and analyzed with strain gauge method. Impressions were anatomic impression technique and functional impression technique. The following conclusions were drawn from this syudy. 1.The stress at the abutment tooth on all RPD was decreased in functional impression except RPI clasp retained RPD. 2.The stress at the abutment tooth on RPI clasp retained RPD was the most smallest in anatomic impression 3.While load is increase the stress at the abutment tooth was increased, but the change of stress at the buccal side of abutment tooth was not too much in functional impression.

Orthostatic hypotension with other signs of progressive neuronal degeneration particularly affecting the autonomic nervous system has been recognized independently and is called Shy-Drager syndrome. Degenerative changes in the autonomic ganglia, loss of neurons in the intermediolateral columns and degenerative changes in the neurons of the cortex and basal ganglia have been reported on examination of this condition. The authors report a case of Shy-Drager Syndrome with symptoms of orthosatatic hypotension, dysarthria, Parkinson's features, muscle wasting, sexual impotence, atonic bladder and loss of sweating.

Hand, foot and mouth disease, a distinctive clinical syndrome caused by a coxsackie virus, is clinically characterized by vesicles appearing on the hands, feet and in the mouth. The infection begins with a fever and mouth lesions consisting of small vesicles surrounded by red areolae on the buccal mucosa, tongue, soft palate and gingiva. The disease usually lasts spontaneously between 7 to 10 days after onset. We observed 20 cases of hand, foot, and mouth disease from July, 12th to September, 4th, 1979 and examined histopathologically and virologically. We have isolated only one viral strain showing cytopathic effect on HeLa cell among the five cases of acute stage and also observed that viral particle in the electronmicroscope.
