This study was attempt to derive the aging trajectories of Korean elderly people and identify its characteristics. In particular, this study used the successful aging model of Rowe and Kahn as an analytical framework. Using the Korean Longitudinal Study of Ageing(KLoSA), this study applied group-based multi-trajectory analysis to identify multiple aging trajectories in sample of Korean elder aged 65~74(n=2,682). This study also used several demographic characteristics as baseline predictors to identify the characteristics of each aging trajectory. Five dimensions were analyzed in the multi-trajectory model: chronic disease, physical functional limitation, cognitive functioning, depressive symptom and social engagement. As a result of the analysis, five aging trajectories were identified: successful aging(17.8%), usual aging (33.9%), health declining aging(18.2%), pathological aging(7.9%), and aging with mild cognitive impairment(22.1%). In general, the odds of experiencing successful aging were high in men, low-aged, highly educated, high-income, and spousal elderly. On the other hand, for the elderly, who are under-educated, low-income, and high-aged, there was a high probability of experiencing a relatively difficult aging process. In particular, the odds of experiencing a mild cognitive impairment aging was high in older, lower-income women without a spouse.

A 42-year-old female was referred to our department after find out submucosal tumor type lesion on cardia at local clinics. She experienced no specific symptom. On gastroscopy, two distinct neoplasms were detected. One of which was located in the cardia anterior wall of the stomach with the size of 2.0×1.1 cm, and the other one was localized in the cardia posterior wall of the stomach and its size was 1.5×1.2 cm. We performed endoscopic submucosal dissection. Pathological evaluation revealed the diagnosis of gastrointestinal stromal tumor (GIST) at the cardia anterior wall and malignant lymphoma from the mass localized cardia posterior wall of the stomach. We would like to report these rare synchronous tumors which were successfully treated by endoscopic resection in the same patient

Objectives : Ulcerative colitis is a chronic recurrent inflammatory disease of the gastrointestinal tract. However, there are some drawbacks to long-term drug therapy such as the risk of opportunistic infections. Recently, there was an increasing interest on the use of khorasan Kamut wheat because of their higher value of selenium and fiber than modern wheat. The present study was aimed to investigate the effect of Kamut brand wheat enzyme (Kamut WE) diet on colon health in dextran sulfate sodium (DSS)-induced colitis mice. Methods : Female C57BL/6J mice were divided into 6 groups. (1) normal (Water and AIN-93G diet), (2) control (1.25% DSS and AIN-93G diet), (3) Kamut WE (1.25% DSS and Kamut WE diet), (4) normal (Water and AIN-93G diet), (5) control (2.50% DSS and AIN-93G diet), (6) Kamut WE (2.50% DSS and Kamut WE diet). Dietary intake, body weight change, disease activity index (DAI), colon length and spleen weight were monitored. Results : Kamut WE group alleviated colitis symptom, including dietary intake loss, DAI (weight loss, loose stools, bleeding), colon length shortening and spleen swelling. Further, Kamut WE diets showed a significant effect against pathological damage by the increased colon length, decreased DAI and spleen weight in DSS 1.25% as well as DSS 2.50%. Conclusions : Our study provides evidence that Kamut WE diet increased colon length, decreased DAI and spleen weight in intestinal inflammation.

Background : Pulmonary hamartomas are the most common form of benign tumors, occurring in approximately 0.2% of routine autopsies. However, only a few reports on the clinical characteristics of pulmonary hamartoma in Korea have been published. Materials and Methods : The charts, X-rays and pathological specimens of 29 pulmonary hamartoma patients who were diagnosed by a pathological examination from 1990 to 1999 at the Catholic Medical Center were retrospectively reviewed. Results : The peak incidence of the tumor occurred in the sixth decade of life (37.5%). Seventeen patients (58.6%) were asymptomatic and 12 patients (41.4%) had symptoms. Chest discomfort was the most common symptom (31.0%). A total of 25 tumors (86.2%) were parenchymal, and 4 (13.8%) were endobronchial. Twenty cases were in the right lung and 9 cases were in the left lung (approximately 1:2.2). The RLL was the most commonly involved lobe (31.0%). Calcification was noted in 5 cases(19.2%) on a plain X-ray and in 5 cases (29.4%) on chest CT. Accompanied neoplasms were observed in 2 cases. Twenty-four hamartomas (82.8%) were diagnosed by a surgical resection and 4 cases(13.8%) were diagnosed by a fine needle aspiration biopsy. Twenty-six hamartomas (89.7%) were managed by a surgical resection. The follow up ranged from 4 to 55 months (mean, 19.6 months) and no recurrent pulmonary hamartomas were noted. Conclusion : Pulmonary hamartoma is more common in females and more commonly in the right lung. Calcification was noted only in 19.2% on a plain chest X-ray and 29.4% on a chest CT. No recurrent hamartomas had developed during the follow up period.

Purpose: The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. Materials and Methods: We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. Results: There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Conclusion: Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiothery.

Objectives : Vascular endothelial growth factor(VEGF), one of potent cytokines, and its receptors were related with various biological functions and pathological conditions. The purpose of this study was to investigate the changes of serum level of free VEGF, soluble VEGFR-1, and soluble VEGFR-2 after treatment with atypical antipsychotic drug in schizophrenia. Method : The schizophrenic patients were diagnosed with DSM-IV and were prospectively followed up for 4 and 8 weeks. Thirteen schizophrenic patients were evaluated their clinical assessment with serum levels of free VEGF, sVEGFR-1, sVEGFR-2, and positive and negative symptom scale(PANSS) at baseline, 4 weeks, and 8 weeks after treatment with atypical antipsychotic drug. Thirteen normal control subjects were recruited and matched with the patient group by age and sex. Result : The serum level of free VEGF($295.2{\pm}43.7$pg/ml)and sVEGFR-2($8259{\pm}336.7$) at baseline(before treatment) in schizophrenic patients were not significantly different, compared with the control group($199.0{\pm}28.8$ and $8481{\pm}371.9$) respectively. However, the serum level of sVEGFR-1($86.2{\pm}10.3$, p<0.05) was significantly increased in the schizophrenic patients compared with the control group($59.0{\pm}6.4$). After treatment with antipsychotic drug, the serum levels of free VEGF at 4 weeks($338.9{\pm}56.5$) and 8 weeks($309.5{\pm}58.7$) were not significantly, different compared with baseline. But the serum levels of sVEGFR-1 was significantly decreased at 8 weeks ($57.3{\pm}6.3$, p<0.05) after antipsychotic drug treatment. The serum levels of sVEGFR-2 were decreased at 4 weeks ($7761{\pm}403.0$, p<0.05) and 8 weeks($7435{\pm}333.5$, p<0.05) compared with baseline. Conclusion : The decreased serum level of sVEGFR-1 and sVEGFR-2 might be affected by dopaminergic system which was influenced by antipsychotic drug.

Purpose : Authors investigated the efficiency of preoperative MRI in suspicious glomus tumor and the clinical outcomes after marginal excision. Materials and Methods : In 10 cases of glomus tumors in the fingers, authors retrospectively analyzed the clinical data, including previous trauma, treatment history, preoperative symptoms, physical examination, plain radiography, MRI (9 cases), pathological findings and postoperative complications. Results : The patients had pain in 10 cases, tenderness in 9 cases, cold sensitivity in 3 cases and edema in one case. MRI showed low signal (3 cases) or iso-signal (5) intensity on T1 weighted image, high signal intensity (8) on T2 weighted image, and all the lesions were enhanced in gadolinium enhancement images. The exact locations of glomus tumors were median in 6 cases, lateral in 5, lateral fold in 2 and pulp in 3 in transverse section and nail bed in 5 cases and nail matrix in 5 in sagittal section. Marginal excision was performed by lateral approach in one case and transungual in 9 cases. Histologically, all 10 cases were composed of solid sheets of round cells interrupted by thin-walled blood vessels. Most of clinical symptoms were disappeared in all cases after operation. Nail deformity was found in one case, which was originated from nail matrix, however, there was no recurrence. Summary : Clinical symptom was the most impotant factor in diagnosis of glomus tumor in the fingers. However, preoperative MRIs were helpful in patients, who had obscure pain or prolonged clinical symptoms with suspicious glomus tumors. Preoperative MRI might be one of the most useful tools for establishing the exact diagnosis and detecting the location of glomus tumors, in spite of the relatively high expenses.

An isolate of Cucumber mosaic virus(CMV), called as Can-CMV, was originally isolated from Canna generalis showing typical streak mosaic foliar symptoms, and its properties were investigated in this study. Whereas all known isolates of CMV could induce symptoms on their systemic hosts(four kinds of Nicotiana spp and a zucchini squash), Can-CMV induced no symptoms on its systemic hosts tested. Replication and movement of the virus on upper leaves as well as inoculated leaves-were confirmed by RT-PCR suggesting that Can-CMV could only infect systemically on N. benthamiana and N. glutinosa. Size of local lesions on the Can-CMV-inoculated leaves of Chenopodium amaranticolor was much smaller than that of Fny-CMV. Whereas Fny-CMV and LS-CMV could induce distinct necrotic local lesions on Vigna unguiculata 2 to 3 days postinoculation(dpi), chlorotic spots symptom was expressed by Can-CMV 4 to 5 dpi. Virus-specific 4 kinds of dsRNAs were isolated from leaves of N. benthamiana infected with Can-CMV, and these dsRNAs corresponded to the viral genomic RNAs and subgenomic RNAs and their patterns were indistinguishable to those of Fny-CMV and LS-CMV. By restriction mapping analysis of 950 bp of RT-PCR amplified products of coat protein gene of the virus as well as by serological analysis of gel diffusion test, Can-CMV belongs to a typical member of CMV subgroup IA. These results suggest that the Can-CMV isolated from C. generalis possesses unique pathological properties to understand further insight into the various interactions between virus and host.

Although it is not a pathological symptom, Dentinal Hypersensitivity (DH) describes pain felt by patients whose tooth roots are exposed outside of the gums and are therefore sensitive to external stimuli. DH is caused by tooth brushing or gum diseases and treatment to reduce the sensitivity can include use of materials having stimulation activity for DH or a resin material applied periodontally. This study examined the hypersensitivity treatment effects of a four-week treatment with a toothpaste containing hydroxyapatite and tricalcium phosphate (Hap-TCP toothpaste). The Hap-TCP toothpaste was made by mixing a commercially available fluorine-containing toothpaste with 10% (W/W) hydroxyapatite and 19% (W/W) tricalcium phosphate (both 99% purity based on XRD analysis). The tooth hypersensitivity treatment effect was surveyed by scoring VRS values, and showed no significant initial difference compared with the control. However, after 1 week of use, the pain reduction value was 8% in the treatment group compared to the control group. This value increased to 30% and 60% after 2 and 4 weeks, respectively. Hypersensitivity to cold stimulation, which was used as a VAS value, showed no initial significant differences compared with the control, but was significantly decreased after 1, 2, and 4 weeks in the experimental group, with more than a 3-fold difference after 4 weeks. These findings confirmed that remineralization can alleviate DH as hydroxyapatite fills dentinal tubules and calcium, phosphorus, and tricalcium phosphate ion equilibrium is established.

Even in our modern era, the projection of monsters in the recent literature contains the critical imagination of human existence for the posthuman age. The meaning of the monster-abject, especially as from the perspective of feministic criticism, contains criticism of the violent and oppressive patriarch as observed in the modern times. This article focuses on the gendered imagination of the discussions of the "abject" discussed by Julia Kristeva, and the "monstrous femine" discussed by Barbara Creed. Kim Eon-Hee's poems and Han Kang's novels, which have been examined extensively for analysis, show that the practical strategy of abject that goes beyond hate and sublime, wonder and joy through the imagination and concepts of monsters. The monster-abject strategy of Kim Eon-Hee's poem can be summarized by the narrative method of mirroring and the imagination of the truncated body. Mirroring falsification, which mimics the male speaker, is a method that some feminists strategically utilize in relation to the problem of female aversion in recent years as noted in the literature. In Kim Eon-Hee's poem, "becoming a man" and "imitating a man," through the method of mirroring appear as an image of cutting to dismantle the body. In that way, the narrative strategy of the abject that draws out abominations and bizarre effects which contains a strong critique of the patriarchal dominant ideology. The monster-abject strategy of Han-Kang's novel is embodied through the being of plants and the process of vegetarian-anorexia process. The world of the adject which was oppressed in the Han-Kang's novel, returns to the senses of the body through the symbol of the body. It is noted that the fictional characters who realize the repressed desire through the pathological symptom expressed by the female, go on to body perform active transformation. The sense of a body in a novel is not only a rejection of the world of animalman-civilization, but also a radically questioning of the noted and recognized boundaries between human beings and non-human being entities. The two writer's works show that the imagination of the monster-adject is not limited to rejecting the existing gender categories, but also goes in the direction of exploring the possibilities of various associated gender actions.
