The changes of the aerobic viable bacterial counts, the content of chemical components and the sensory evaluation in Kimchis which were prepared with Various ingredients (red pepper, green onion, garlic and ginger) and fermentation at $20^{\circ}C$ were investigated. Aerobic viable bacterial counts were suddenly decreased with fermentation, but it was decreased slowly from the second day. Salinity of Kimchis was $1.8%{\sim}2.0%$ and titratable acidify were lower in sample 2 (deleted red pepper) and 3 (deleted green onion) on the first day but sample 4 (deleted garlic) after the fifth day. Total sugar content was decreased from $1.8{\sim}2.7g/100g$ to $0.8{\sim}1.1g/100g$ during fermentation periods. Carbon dioxide content maintained relatively higher in sample 2 and 5 (deleted ginger) with fermentation. Volatile organic acid content showed no difference in all Kimchis with fermentation. During the whole fermentation period, appearance was the worst in sample 2. Texture, off-flavor and overall-eating quality were the worst in sample 4. Carbonated flavor and overall eating quality were the best in sample 5.

Changes in the quality characteristics of muskmelon were analyzed by treating samples with 500, 1,000, and 1,500 ppb 1-MCP every 4 days and then storing the samples at $10^{\circ}C$. The weight losses of the MCP treated samples were lower than those of the control, while there were no differences in the concentrations among treatments. The firmness was maintained at a higher value in 1-MCP treated samples than the control during the storage period and showed the highest value in the 1,000 ppb treatment. The L-values (brightness of samples) in the 500 and 1,000 ppb treatments were kept constant during the storage period, while that of the control showed a decreasing trend after four days of storage. The bvalues and yellowness, were decreased after showing an increasing trend in both treatments and the control as the storage period passed. The respiration rates of 1-MCP treated samples were lower than the control, with the lowest value being observed in the 1,000 ppb treatment. The texture observed upon sensory evaluation was higher and freshness was maintained longer in the 1,000 ppb treatment. Therefore, 1,000 ppb 1-MCP was considered to be the most effective concentration for treatment of muskmelon.

Purpose : Endometriosis is a steroid dependent disease with a particular genetic background but the location of possible genomic aberrations are still poorly clarified. This study was designed to investigate the associations between the polymorphism of the progesterone receptor gene (PROGINS) and endometriosis. Methods : 100 women with surgically diagnosed and histologically confirmed endometriosis were enrolled as a patient population and a total of 110 female control subjects undergoing health examination were enrolled as control population. DNA extraction and polymerase chain reaction (PCR) were used to genotype women for the presence of the PROGINS polymorphism in peripheral blood samples. The x2-test was used to compare genotype distributions between endometriosis and controls. Results : T1/T2 heterozygote was found to be one patient in each group, and the rest of the subjects were all T1/T1 homozygotes. There was no difference in the genotype distribution between the endometriosis group and the control group. Conclusion : These results suggest that the progesterone receptor gene PROGINS is not associated with the risk for endometriosis.

Purpose Patient motion during myocardial perfusion SPECT can produce images that show visual artifacts and perfusion defects. This artifacts and defects remain a significant source of unsatisfactory myocardial perfusion SPECT. Motion correction has been developed as a way to correct and detect the patient motion for reducing artifacts and defects, and each motion correction uses different algorithm. We corrected simulated motion patterns with several motion correction methods and compared those images. Materials and Methods Phantom study was performed. The anthropomorphic torso phantom was made with equal counts from patient's body and simulated defect was added in myocardium phantom for to observe the change in defect. Vertical motion was intentionally generated by moving phantom downward in a returning pattern and in a non-returning pattern throughout the acquisition. In addition, Lateral motion was generated by moving phantom upward in a returning pattern and in a non-returning pattern. The simulated motion patterns were detected and corrected similarly to no-motion pattern image and QPS score, after Motion Detection and Correction Method (MDC), stasis, Hopkins method were applied. Results In phantom study, Changes of perfusion defect were shown in the anterior wall by the simulated phantom motions, and inferior wall's defect was found in some situations. The changes derived from motion were corrected by motion correction methods, but Hopkins and Stasis method showed visual artifact, and this visual artifact did not affect to perfusion score. Conclusion It was confirmed that motion correction method is possible to reduce the motion artifact and artifactual perfusion defect, through the apply on the phantom tests. Motion Detection and Correction Method (MDC) performed better than other method with polar map image and perfusion score result.

A 4-year-old female Shih-tzu dog weighing 5.1 kg was referred with abdominal distension and diagnosed as cystic papillary adenocarcinoma with metastasis to serosal surface of abdomen by biopsy. Intraperitoneal chemotherapy with cisplatin (50 $mg/m^2$) diluted in normal saline (250 $ml/m^2$) was initiated following removal of ascites one month after ovariohysterectomy (OHE). Clinical response was great and had no side effects during the chemotherapy period (3 relapses, 33 months after diagnosis). However, pleural effusion occurred with ascites and renal failure at the end of treatment. Eleven treatments of cisplatin were performed during 35 months after diagnosis. Intraperitoneal cisplatin instillation has been effective to control malignant ascites and pleural effusion in ovarian cancers and could be a reasonable palliative treatment. This is the first case report describing intraperitoneal cisplatin chemotherapy in metastatic ovarian cyst papillary adenocarcinoma in Korea.

This study was carried out to investigate the characteristic quality of jeungpyun added Paecilomyces japonica with different fermentation time. The volume of jeungpyun added Paecilomyces japonica was more increased after fermentation. The volume was decreased when the fermentation was progressed. The pH was 5.1 before fermentation and the pH decreased when the fermentation was progressed. Moisture content was more increased as the time of fermentation became longer. Hunter color test, L value and b value appeared the highest after 1st fermentation, and it appeared lesser when the time of fermentation became longer. In measurement of texture, hardness showed the highest value when 90 minutes passed after the 2nd fermentation. Gumminess and brittleness were tend to increase when it have longer fermentation time. In scanning electron microscopic observation, organization of sponges was tend to break down as the fermentation time was longer. Sensory properties showed that color intensity was more strong when second fermentation was progressed, and hardness, toughness, sourness were high when the fermentation time was longer. In conclusion overall acceptability of jeungpyun, 3$0^{\circ}C$, 3 hours after 1st fermentation and 2nd fermentation for 30 minutes, 35$^{\circ}C$ showed the most preference.

In the present paper, we investigated the quality stability of mackerel based burger during frozen storage. The moisture and crude lipid contents of products were $60.2{\sim}61.5%$ and $14.7{\sim}14.9%$, respectively. The pH showed a tendency of decrease, while volatile basic nitrogen content showed a tendency of increase during frozen storage. The histamine content was $2.60{\sim}2.81\;mg/100g$, and this value increased slowly during frozen storage. The increasing ratio in the peroxide value, carbonyl value, TBA value, fatty acid composition and color value of vacuum packed product and antioxidants added product were lower than those of air packed product. The texture profile analysis parameters such as hardness and toughness showed a tendency of a slight increase in air packed product and showed less increase in vacuum packed product and antioxidants added product. From the results of chemical experiments and sensory evaluation during frozen storage, it is concluded that the vacuum packed mackerel based burger and antioxidants added mackerel based burger were good condition for preserving the quality during frozen storage of 60 days.

We examined the wound healing effect and toxicity of Forsythia suspensa extract to verify the therapeutic usefulness on wound treatment. Additionally, we examined its antibacterial effect. The wound healing effect of Forsythia suspensa extract was compared with the tetrachlorodecaoxygen anion complex (TCDO), protein free haemodialysate (Haemyl), and physiological saline. The wound areas on the 4th, 11th, 14th day of treatment with Forsythia suspensa extract, TCDO, and Haemyl were significantly smaller than with the saline treatment. The wounds on the 8th day of treatment with Forsythia suspensa extract were only siginificantly smaller than the saline treatment. On the 8th day of treatment with Forsythia suspensa extract, TCDO, and Haemyl accerlerlated the wound epithelization more than saline treatment. There was not a significant difference in liver enzyme activity (GOT, GPT) and blood cell count between the Fosythia suspensa extract and the saline treatment. In addition, the Forsythia suspensa extract did not inhibit bacterial proliferation. These results suggest that Forsythia suspensa extract has great possibility of being developed into new wound healing drugs. Its pharmacological effects seem to have no relation with antibacterial effect.

The purpose of this study was to investigate the effect of Ligularia fischeri powder on the functional and sensory characteristics of Mandupi. Various Mandupi samples were prepared with wheat flour by addition of different amounts of Ligularia fischeri powder, and instrumental characteristics and sensory evaluations were then investigated. Based on amylograph data, the composite of Ligularia fischeri powder and wheat flour samples increased its gelatinization temperatures depending on increasing of Ligularia fischeri powder content. However, viscosities at $95^{\circ}C$ and after 15 min, and maximum viscosity were reduced. In terms of Hunter's color values, L and a values decreased, while b value increased with the increase of Ligularia fischeri powder content. In addition, weight, volume and turbidity of Mandupis prepared with Ligularia fischeri powder were significantly greater than those of control. In terms of textural characteristics, springiness, chewiness and brittleness increased whereas adhesiveness decreased with the addition of Ligularia fischeri powder. Sensory evaluations showed that the overall preference of Mandupi with the addition of 3% Ligularia fischeri powder was greater than that of wheat flour only.

Full-mouth reconstruction of a patient using dental implants is a challenge if there is vertical and horizontal bone resorption, since this includes the gingival area and restricts the position of the implants. however, hard- and soft-tissue grafting may allow the implants to be placed into the desired position. Although it is possible to regenerate lost tissues, an alternative is to use fixed detachable prostheses that restore the function and the esthetics of the gingiva and teeth. Various material combinations including metal/acrylic, metal/ceramic, and zirconia/ceramic have been used for constructing this type of restoration. Other problems include wear, separation or fracture of the resin teeth from the metal/acrylic prosthesis, chipping or fracture of porcelain from the metal/ceramic or zirconia/ceramic prosthesis, and fracture of the framework in some free-end prostheses. With virtually unbreakable, chip-proof, life-like nature, monolithic zirconia frameworks can prospectively replace other framework materials. This clinical report describes the restoration of a patient with complete fixed detachable maxillary and mandibular prostheses made of monolithic zirconia with dental implants. The occluding surfaces were made of monolithic zirconia, to decrease the risk of chipping or fracture. The prostheses were esthetically pleasing, and no clinical complications have been reported after two years.
