For the Evaluation of X-ray image intensifier, we measured radiation dose at input of I. I., brightness and fluorescence at output of I. I. by using X-ray exposure meter, optometer and fluorescence meter for the relative conversion factor. Especially, by using fluorescence meter, we could easily get relative conversion factor without having regulated machine by JIS. Since using, the quality of image intensifier is going down. Consequently, it needs continuous quality maintenance.

Purpose: Laser epithelial keratomileusis (LASEK) is a refractive surgery technique in which the cornea is covered with the epithelial flap after keratectomy. However, there have been reports of tissue damage by the alcohol utilized in this procedure while preparing the epithelial flap, which has led to novel methods. One of these is the mechanical designing of the epithelial flap named epipolis laser assisted in situ keratomileusis (Epi-LASIK). This study evaluates the histologic features and wound healing process of the corneal flap using Epi-Tome, which is the epithelial cutter of the newly introduced Epi-Lasik. Methods: Twenty-four eyes of 12 dogs were devided into two groups. In one group (n=12), 20% alcohol was used and, in the other group (n=12), Epi-Tome (Gebauer, Germany) was used to make a corneal flap. The size change of a fluorescein-stained epithelial defect was followed postoperatively at 6, 12, 24, and 36 hours. Results: The maximum decrease in defect size were observed at 0 to 6 hours in the Epi-Tome group, and from 6 to 12 hours in the alcohol group; the value were 10.01±5.32 mm2 and 9.23±4.75 mm2 respectively. Histologic review revealed that there was less tissue damage and smoother cut edge in the Epi-Tome group compared to the alcohol group, and the adhesion between stroma and epithelium was faster in the Epi-Tome group. Conclusions: Mechanically detached corneal flaps had favorable chances of survival such that re-epithelialization occurred early in the postoperative phase. A few epithelial fragments at a corneal section plane prevent corneal opacification and minimize inflammatory reaction, thus reducing postoperative pain.

Objective : We investigate toxicity of Aconiti ciliare tuber and antioxidant activity of Aconiti ciliare tuber Pharmacopuncture to develop safe Aconiti ciliare tuber Pharmacopuncture and find out the effect. Methods : In order to investigate toxicity of Aconiti ciliare tuberm, we administered Aconiti ciliare tuberm orally to rats and examined the survival rate, comparing with the survival rate of rats administered by Radix aconitum simmered with Semen Glycine and Radix Glycyrrhizae. We examined the in vitro biological activity of Aconiti ciliare tuber Pharmacopuncture, including the total polyphenol content, and ABTS radical scavenging. Results and Conclusions : The $LD_{50}$ of Radix aconitum simmered with Semen Glycine and Radix Glycyrrhizae was 9.0g/kg, on the other hand, the $LD_{50}$ of Aconiti ciliare tuberm was more than 15g/kg. The total polyphenol contents of Aconiti ciliare tuberm Pharmacopuncture was 2.31mg/L. The 2,2'-azinobis-3-ehtlbezothiazoline-6-sulfonic acid radical decolorization (ABTS) was 10.26%. We conclude that Aconiti ciliare tuberm is not highly toxic, Aconiti ciliare tuber Pharmacopuncture has a little antioxidant effect.

Reactive Oxygen Species(ROS) are continuously produced at a high rate as a by-product of aerobic metabolism. Since tissue damage by free radical increases with age, the reactive oxygen species(ROS) such as hydrogen peroxide($H_2O_2$), nitric oxide(NO). Several lines of evidence provided that ROS appears to cause to develop aging-related various diseases such as cancer, arthritis, cardiovascular disease. Our reserch objective was to examine the in vitro biological activity of Scolopendrid Pharmacopuncture, including the total poly-phenol content, DPPH radical scavenging, ABTS radical scavenging, Superoxide dismutase(SOD)-like activity, Nitrite scavenging ability. The total poly-phenol contents of Scolopendrid Pharmacopuncture was 35.859mg/L. Elctron donation ability on DPPH was 36.82%. The 2,2'-azinobis-3-ehtlbezothiazoline-6-sulfonic acid radical decolorization (ABTS) was 84.7%. The superoxide dismutase (SOD)-like activities of Scolopendrid Pharmacopuncture was 44.33%. The nitrite scavenging effects were pH dependent, and were highest at pH 1.5(45.2%) and lowest at pH 6.0(11.3%). We conclude that Scolopendrid Pharmacopuncture may be useful as potential sources of antioxidant.

Purpose: To evaluate the effectiveness of graded (adjustable intraoperatively) partial vertical rectus muscle tenotomy at the insertion in correcting small degrees of hypertropia. Methods: All patients with best corrected visual acuity of better than 6/30 in both eyes who had undergone only partial tenotomy of vertical rectus muscle(s) over a 30-month period were included. Improvement was evaluated 6 weeks postoperatively as the change in alignment in prism diopters (PD) in primary gaze and in the field of action of the affected rectus muscle(s). Binocular function was evaluated by Titmus stereoacuity and the Worth 4-light tests. Results: All 24 patients who met the inclusion criteria had diplopia preoperatively, and this had resolved in 17 (71%) postoperatively (P<0.005). Prisms were used by 6 preoperatively vs. 2 postoperatively (P<0.05). The average vertical deviation in primary gaze decreased from 8 PD to 2 PD (P<0.005). In the field of action of the treated rectus muscle, hypertropia decreased from an average of 8 PD to 3 PD (P<0.005). For the available pre- and post-operative assessments, stereoacuity improved after 10 of the 18 (56%) procedures and Worth 4-light testing showed improvement or maintenance of fusion after 13 of 19 procedures (68%). Conclusions: Graded vertical rectus partial tenotomy can effectively reduce small degrees of hypertropia and associated diplopia, improve binocular function, and reduce or eliminate the need for prism correction.

In this study, 12 environmental factors were used to evaluate the potential habitat of Pteromys volans living around some development areas. The analyzed value ranged from 0 to 20.1, and the area with a score of 10 or less was analyzed to have a low possibility of inhabiting Pteromys volans. To verify the analyzed results, a field survey was conducted on areas with 10 or more scores, and traces of habitat of Pteromys volans were confirmed in areas with 16 or more scores. All the areas with an evaluation score of 16 or higher showed high crown density and age class. However, despite the high crown density and age class, the evaluation score in some areas was low owing to the influence of other environmental factors. Therefore, in evaluating Pteromys volans habitats, it is necessary to apply various and complex criteria suitable for field conditions rather than applying uniform and fragmentary environmental factors only.
