9Objective : We carried out this experimental study in order to investigate the effect of Chaenomelis Fructus(木瓜) extract and herbal-acupuncture on the arthritis induced by injecting Freund's complete adjuvant Method : 1. We categorized SD-rats into five groups as followings. (1) Control: Without any Treat (2) Treat I: treated by acupuncture (3) Treat II: treated by drinking 5% saline (4) Treat III: treated by drinking Chaenomelis Fructus(木瓜) extract (5) Treat IV: treated by Chaenomelis Fructus(木瓜) herbal-acupuncture 2. We established ten items for decision of experimental results as followings Edema rate, Pain endurance, WBC, Hemoglobin, Platelet, Total protein, Albumin, Globulin, RA factor, CRP Results : The groups that showed significant effects compared with Contol group were explained as followings. 1. Edema rate : Treat I , Treat III 2. Pain endurance : Treat I, Treat IV 3. WBC : Treat IV 4. Hemoglobin : Treat III 5. Plat99elet : Treat IV 6. Total protein : Treat I, Treat IV 7. Albumin : None 8. Globulin : Treat I, Treat IV 9. RA factor : Treat I, Treat IV 10. CRP : Treat IV Conclusion : Observing above experimental results, we can guess that the effects of acupuncture and Chaenomelis Fructus(木瓜) herbal-acupuncture on Freund's adjuvant arthritis are more superior than other ways. In addition, we can find that the latter is more better than the former in effect by two items(platelet, CRP).

Background: The role of nitric oxide(NO) in analgesia from opioids is controversial. On the one hand, IV morphine analgesia is enhanced by IV injection of NO synthase inhibitors. On the other hand, IV morphine results in increased release of NO in the spinal cord. There have been no behavioral studies examining the interaction between IV morphine and intrathecal injection of drugs which affect NO synthesis. Method: Rats were prepared with chronic lumbar intrathecal catheters and were tested withdrawal latency on the hot plate after 3~5 days of surgery. Antinociception was determinined in response to a heat stimulus to the hind paw before and after IV injection of morphine, 2.5 mg/kg. Twenty minutes after morphine injection, rats received intrathecal injection of saline or the NO synthase inhibitors, L-NMMA or TRIM, the NO scavenger, PTIO, or the NO synthase substrate, L-Arginine. Intrathecal injections, separated by 15 min, were made in each rats and measurements were obtained every 5 min. Result: Mophine produced a 60~70% maximal antinociceptive response to a heat stimulus in all animals for 60 min in control experiments. Intrathecal injection of idazoxane decreased antinociception of IV morphine. The NO synthase inhibitors and the NO scavenger produced dose-dependent decreases in antinociceptive effect of morphine, whereas saline as a control group and L-Arginine as the NO substrate had no effect on antinociception of morphine. Conclusion: The present study supports the evidences that systemic morphine increase the nitrite in cerebrospinal fluid and dorsal horn. These data suggest that the synthesis of NO in the spinal cord may be important to the analgesic effect of IV morphine and increased NO in spinal cord has different action from the supraspinal NO.

This study compared the surface roughness and surface characteristics between a type IV stone and scannable stone. Materials used were a type IV stone, two different kind of scannable stone. Ten specimens per experimental group were prepared according to manufacturer's direction. Surface roughness of specimen was measured using profilometer. The measurement was based on the standard of Japanese Industrial Standards 1994. The mean and standard deviations of each reference point were analyzed using one-way ANOVA and Scheff$\acute{e}$ post hoc test. The program used to handle statistical analysis was SPSS 20.0 and the significance level was set at 0.05. The difference of surface roughness was statistically significant in order of Scannable Stone $10.07{\pm}0.02{\mu}m$, Scannable Stone $20.08{\pm}0.03{\mu}m$, Type IV $0.10{\pm}0.04{\mu}m$. These results will have to be confirmed in further clinical application researches.

Objective : The purpose of this study was to investigate the cognitive performance of major depressive disorder (MDD) in military service/conscription personnel who visited the psychiatric clinic for a medical certificate to consider the situation from the perspective of Korea's unique compulsory military system. We used the Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV) as the test for verifying the suitable level of cognitive functioning for military service and as the embedded measure with reflecting suboptimal effort. Methods : The study was conducted on 56 (28 males, age 19-34) in/out-patients admitted to the psychiatry department and diagnosed with MDD (DSM-IV). All participants completed a structured clinical interview (MINI-Plus), as well as self-report questionnaires related to demographics and severity of clinical symptoms. K-WAIS-IV was administered to each subject to assess cognitive characteristics. Results : Military group showed significantly lower processing speed index (PSI) score including subtests of symbol search (SS) and coding (CD) score, compared to the control group. There was no other significant differences in the Full Scale IQ (FSIQ), Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI) scores including sub-tests comprised of the above indices, and Reliable Digit Span (RDS), Enhanced-RDS-Revised (E-RDS-R) between the study and control groups. Conclusion : This study was the first effort to verify the characteristics of Korea's military group with MDD and suggest the applicability of PSI and processing speed of K-WAIS-IV as an embedded performance index to test sub-optimal effort or low motivation beyond the purpose of testing cognitive deficits.

Crystalline products were obtained when$TiCl_4$ was reacted in dichloromethane with acetic, propionic, crotonic, benzoic, furoic and salicylic acids. Chemical analysis has shown that these were all dichlorodicarboxylatotitanium (IV). Cryoscopy of dichlorodipropionatotitanium (IV) indicated the carboxylato-complexes are dimeric. In the IR spectra of these complexes two strong bands both assigned to asymmetric carbonyl stretching vibration have been observed in the region$1500 - 1700cm^{-1}$ and the NMR spectrum of dichlorodipropionatotitanium (IV) has also shown two triplets and two quartets, which indicate that there are two chemically unequivalent carboxylato-ligands in the dimer $[TiCl_2(OOCR)_2]_2$. Their molecular structure was proposed to be bis-carboxo-bridged dimer.

Purpose: This study compared the surface hardness (Vickers) and microstructural characteristics between a type IV stone with and without die hardening treatment, a polyurethane die material. Methods: Materials used were a type IV stone(MG Crystal Rock), two die hardeners (Hardening bath, Epox-it), and a polyurethane resin material(Polyluck). Six specimens per group were prepared according to manufacturer's directions. The prepared specimens were tested by means of hardness test, one-way ANOVA analysis, scanning electron microscopic(SEM) observations and energy dispersive spectroscopic(EDS) analysis. Results: In the hardness test and its statistical analysis, there was no significant difference in the surface hardness between a type IV stone and type IV stone with die hardener coating, type IV stone mixed with an epoxy like material instead of water. In contrast, polyurethane resin material exhibited significantly greater surface hardness than other specimen groups (p<0.05). Conclusion: By considering the results of the hardness test, SEM observations and EDS analysis, although the die hardeners on type IV stone did not show remarkable improvement in surface hardness, the die hardener coating on the surface of type IV stone material did show decrease of microporous and improvement of surface defects.

Antireflux surgery has been indicated in gastroesophageal reflux disease (GERD) that does not respond to medical treatments. Although the most commonly performed operation is Nissen fundoplication, Belsey Mark IV fundoplication is indicated for more complicated cases, such as, in cases of a failed Nissen operation or a long lasting hiatal hernia. Here, we report a case of Belsey Mark IV fundoplication for a failed Nissen fundoplication. The infant developed frequent times of aspiration pneumonia after initial Nissen for a hiatal hernia with GERD during the newborn period. At 15 months of age, a $2^{nd}$ Nissen operation was attempted, but fundoplication was not available because of excessive mesenteric adherence to the liver and cardia. Therefore, Belsey Mark IV fundoplication was performed via trans-thoracic approach, which can provide full esophageal mobilization and better visualization of the herniated fundus and the surrounding tissues. Subsequently, she has shown an improved general condition without GERD.

Background: The purpose of this study was to detect signals of adverse events (AEs) of DPP-IV inhibitors using the KIDs-Korea Adverse Event Reporting System (KAERS) database. Methods: This study was conducted using AEs reported from January 2009 to December 2018 in the KIDs-KAERS database. For signal detection, disproportionality analysis was performed. Signals of DPP-IV inhibitor that satisfied the data-mining indices of reporting odds ratio (ROR) were detected. Results: Among the total number of 10,364 AEs to all oral hypoglycemic agents, the number of reported AEs related to DPP-IV inhibitors was 1,674. Analysis of reported AEs of DPP-IV inhibitors at the SOC levels showed that Respiratory system disorders were the highest at 4.31 (95% CI 3.01-6.17), followed by Skin and appendages disorders at 2.04 (95% CI 1.74-2.38). When analyzing AEs reported at the PT level, pharyngitis was the highest at 73.90 (95% CI 17.59-310.49), followed by arthralgia at 6.08 (95% CI 2.04-18.11), and coughing at 5.21 (95% CI 2.07-13.15). Conclusions: Based on the result of the study, deeper consideration is required according to the characteristics of the patients in prescribing DPP-IV inhibitors among oral hypoglycemic agents, and continuous monitoring of the occurrence of related Adverse Drug Reactions during administration is also required.

Purpose: The prognosis for patients with a Borrmann type IV gastric cancer is extremely poor despite an aggressive surgical approach. We evaluated the clinicopathological features for Borrmann type IV cancers to find treatment strategy. Materials and Methods: The 1098 patients with advanced gastric cancer who underwent surgical resection between 1990 and 2001 were analyzed. These patients were divided into two groups: 81 patients with a Borrmann type IV carcinoma, and 1017 patients with all other types of gastric carcinomas. Results: Patients with a Borrmann type IV carcinoma were younger than those with other types, and female was prevalent (p=0.000). Of the patients with a Borrmann type IV gastric carcinoma, 68 patients (84%) were classified as stage III or IV at the initial diagnosis. The histologic type was commonly undifferentiated and serosal infiltration; nodal involvement and lymphatic invasion were more frequent in patients with a Borrmann type IV than in those with other types of cancer. Multivariate analysis confirmed that the extent of lymph node metastasis was a negative prognostic factor for Borrmann type IV gastric carcinomas. The curability for a Borrmann type IV carcinoma was only 53.1%, and peritoneal dissemination rate was 25.9%. The predominant pattern of recurrence for a Borrmann type IV gastric carcinoma was peritoneal dissemination, and it was significantly different with other types (93.1% vs 55.8%, P<0.05). The 5-year survival rate of patients with a Borrmann type IV gastric carcinoma was significantly lower than those of patients with other types of cancer, even though a curative resection had been accomplished (26% vs 63%, p<0.005). The 5-year survival rates of patients with a Borrmann type IV carcinoma following a curative resection were 44.9%, 24%, and 0% for stages II, III and IV, respectively (p<0.05). Conclusion: Because the prognosis for patients of a Borrmann type IV gastric cancer is extremely poor despite a curative resection, preoperative and/or intraperitoneal chemotherapy should be considered. And diagnostic laparoscopy and peritoneal cytology may be used to play an important role in accurate staging workup. (J Korean Gastric Cancer Assoc 2006;6:97-102)
