  • The cerebellum processes input from other areas of the brain, spinal cord and sensory receptors to provide precise timing for coordinated, smooth movements of the skeletal muscular system. A stroke affecting the cerebellum may cause vertigo, nausea, balance and coordination problems. The papers on central vertigo caused by cerebellar infarction were reported by Kim, Ku, Ko, Choi, and Han. Their cases were classed as Heo hoon, Dam hoon, and Sangchopungyeul yeul dam, and they treated with Jaeumkunbi-tang, Taeksa-tang, Cheonghunwhadam-tang gami, Cheonginwhadam-tang, Hachulbosim-tang. In this paper, three patients who suffered from vertigo were diagnosed as cerebellar infarction. They felt too giddy to walk without any help. After Oriental medical treatment based on Dongeuibogam, their sequelae of cerebellar infarction - vertigo, nausea, ataxia - had improved dramatically. So we report these cases, and suggest Oriental medical treatment based on Dongeuibogam have effect on cerebellar infarction. But more clinical case reports should be further examined.

  • Objectives : Obesity is an important cause of diabetes, and lipotoxicity causes insulin resistance. In this study, we investigated the effects of Salvia miltiorrhiza on high fat diet-induced obese type 2 diabetic mouse models. Methods : Diabetes was induced in ICR male mouse (23~25 g) with Surwit's high fat, high sucrose diet. Mice were divided into 4 groups (n=10) of normal, control, Salvia miltiorrhiza, and metformin. After 8 weeks, body weight, OGTT, fructosamine, lipid profile, serum level of adiponectin and leptin, epididymal fat pad, liver weight and epididymal adipocyte size were measured. Results : Salvia miltiorrhiza significantly reduced oral glucose tolerance levels, fructosamine serum level, epididymal fat weight, and epididymal adipocyte size. Salvia miltiorrhiza also increased HDL-cholesterol, adiponectin and leptin serum levels. Conclusions : These results show that Salvia miltiorrhiza improves insulin resistance. Therefore we suggest that Salvia miltiorrhiza would be an effective treatment for obese type 2 diabetic patients.

  • A surface acoustic wave(SAW) sensor for the detection of odorants has been constructed by depositing various phospholipids and fatty acids onto the surface of the SAW device. Applying the Langmuir-Blodgett technique, it was possible to deposit the optimal number of layers which was found to be between 10 and 20. Menthone, amylacetate, acetoin, and other organic gases showed different affinities to the coated lipids. An explanation is given for different odorant affinities based on the monolayer properties of phospholipids.

  • In this paper we propose a novel electrode structure for high transmittance in the Patterned Vertical Alignment (PVA) LC cell. Normally, the transmittance of PVA LC cell is depended on the shape of the electrode and cell gap. We studied the area decreasing the transmittance through the electrode structure for wide viewing angle and proposed new electrode design to change LC director configuration in the area. We use the 'TechWiz LCD' for calculation of the director configuration and optical characteristics. We show the comparison of the calculated optical transmittance between the conventional PVA mode and the proposed PVA mode. From the results, we confirm that the optical transmittance of the proposed structure of the PVA cell becomes higher.
