CD44 is a family of transmembrane glycoproteins involved in cell-cell and cell-matrix interactions. Expression of CD44 isofonns (splice variants) has been shown to be associated with poor prognosis in several human cancers. We evaluated the expression patterns of the CD44 isofortn (CD 44 splice variant v6) in infiltrating ductal carcinoma of the breast by immunohistochemical and RT-PCR method. Paraffin embedded blocks from seventy-five cases of mastectomized samples were analyzed immunohistochemically using monoclonoal antibody against CD44v6. CD44v6 was detected in fifty-seven cases (76%) of the tumor samples. Adjacent normal myoepithelial cells and ductal epithelial cells revealed focal positive reaction to CD44v6. Thirtytwo cases (80.0%) with lymph nodal metastasis revealed overexpression of CD44v6 monoclonal antibody, but twenty-five cases (71.4%) without nodal metastasis also showed positive reaction to CD44v6 monoclonal antibody, and there is no statistically significant value. Other prognostic factors of infiltrating ductal carcinoma, such as tumor size, histologic grade and hormonal receptors did not show any significant correlation with CD44v6 expression. The RT-PCR studies for 9 cases of infiltrating ductal carcinoma showed the same band patterns both in the normal and tumor tissues. From the above results, it is concluded that the expression of CD44v6 is not a valuable prognostic marker of infiltrating ductal carcinoma of breast.

OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus oral dinoprostone for labor induction at term. METHODS: One hundred of patients at term were randomized to receive either 50microgram of misoprostol vaginally every 4 hours or dinoprostone 0.5mg orally every 1 hour for the maximum of six doses. Intravenous infusion of oxytocin was administered under such circumferences as the patient did not go into active labor after maximum dose, SROM was developed without an adequate contraction pattern, or the patient had arrest of dilatation(no change in cervical dilatation for 2 hours). We compared the frequency of oxytocin augmentation, administration to delivery interval, vaginal delivery rate within 12 hours and 24 hours, intrapartum complications, induction failure, mode of delivery, neonatal outcomes, and maternal complications between two groups. RESULTS: The average interval from administration to delivery was shorter in the misoprostol group(739.4+/-372.4min vs 1087.7+/-765.1min, p<0.05), but the interval from administration to vaginal delivery of each group was similar(724.3+/-375.4min vs 800.3+/-697.0min). Regarding the frequency of vaginal delivery within 24 hours, however, misoprostol group was higher than dinoprostone group(88% vs 56%, p<0.001). And oxytocin augmentation of labor occurred less commonly in misoprostol group than in dinoprostone group(20% vs 76%, p<0.05). Any statistically significant difference in intrapartum complications, mode of delivery, and neonatal or maternal adverse outcome was not appeared between these two group. CONCLUSION: Vaginal misoprostol is as effective and safe as oral dinoprostone for cervical ripening and induction of labor at term. In addition, vaginal misoprostol contributes the curtailment of labor induction expenditure due to its moderate price; misoprostol costs 100 won per 50microgram.

BACKGROUND: Frailty refers to the loss of physiologic complexity and the associated decline in ability to withstand stressors as one gets older. It is defined as unintentional weight loss, exhaustion, weakness, slow walking speed, and low physical activity. According to several western studies, frailty is associated with cognitive impairment, but there have been few studies about the relationship between frailty and cognitive impairment in Korea. Thus, the purpose of this study is to analyze the relationship between cognition and factors related to frailty such as grip strength, walking speed, physical activity, and depression, among female patients older than 65 in Korea. METHODS: A total of 121 subjects among the outpatients of the department of family medicine at Kangbuk Samsung Hospital who did not meet the exclusion criteria were included in this study. We divided the participants into 2 groups, according to the Korean version of the Montreal Cognitive Assessment (MoCA) score: 1 group with subjects that had normal cognition and the other group with patients that had impaired cognition. A comparison was made between the 2 groups in regards to the factors related to frailty, and we completed equation that predicting cognition from the frailty related factors. RESULTS: Compared with the impaired cognition group, the subjects in the normal cognition group had higher hand strength, and walked faster (P<0.001). There was no statistically significant difference in physical activity between the 2 groups (P=0.19). When multiple linear regression analysis was performed using age, grip strength, and walking speed as the predictor variables and MoCA score as the dependent variable, the regression coefficients were calculated to be: -0.2015, 0.2294, 1.2372, and -0.1436, respectively (P<0.05). CONCLUSION: In Korean female patients who are older than 65 years of age, cognition tends to decline as grip strength decreases, walking speed gets slower, depression becomes more severe, and as age increases.

BACKGROUND: Several inhalant allergens are newly identified from arthropods including insects or arachnids recently. Aphids (Heteroptera: Aphididae) are widespread sucking insects, which are parasitic on numerous host plants such as various crops, trees and weeds. Among aphids, Aphis gossypii is a particularly polyphagous species that has been described on almost 300 host plants from various botanical families. Thus A. gossypii is found throughout the country and is a species anyone can easily contact. It is unknown whether aphids have a role in the pathogenesis of respiratory allergy. OBJECTIVE: We assumed that aphids can act as an inhalant allergen on the hypothesis that numerous allergenic materials are released from aphids and become airborne. Using a representative species, A. gossypii, this study was performed to evaluate the antigenicity of an aphid allergen in patients with respiratory allergic diseases. METHODS: Skin prick test with crude extracts of A. gossypii and 50 common inhalant allergens was performed for 225 subjects with respiratory allergic diseases (bronchial asthma and/or rhinitis). A. gossypii-specific IgE (sIgE) were detected by means of ELISA, and IgE- binding components were identified by SDS-PAGE with immunoblot analysis. RESULTS: Of the 225 enrolled subjects, 37 (16.4%) subjects showed positive skin reactivity to A. gossypii. Of them, 17 (7.6%) subjects had A. gossypii-sIgE by ELISA. The SDS-PAGE of A. gossypii extracts showed various protein bands ranging from 9 to 200 kd. Of them, diverse IgE-binding pattern was noted for individual subject by immunoblot analysis. The inhibitory ELISA results indicated that IgE binding to A. gossypii was partially inhibited by the allergenic extracts of house dust mite (HDM), cockroach, or other aphid (Acyrthosiphon kondoi). Finally, A. gossypii-bronchial challenge test was conducted for one asthmatic farmer with skin reactivity to A. gossypii and strong job-related symptoms, but showed no significant response. CONCLUSION: A. gossypii can elicit IgE response in some patients with respiratory allergic diseases. A. gossypii may have a cross-reactivity with HDM and cockroach. Further study will be needed to evaluate its clinical significance in respiratory allergy patients.

Temperature changes during general anesthesia were studied in relation to age, the duration and type of operative procedure(gastrectomy versus tympanoplasty) and the type of anesthetic(halothane versus conflurane) in 41 patients undergoing surgery in our centrally air-conditioned operating room. Body temperatures were recorded every 15 minutes after intubation by measuring the esophageal temperature in adults and the nasopharyngeal temperature in children. A comparison of temperature changes between adults and children showed a significant temperature decreases in adults during general anesthesia(-0.6 degrees C, p<0.001), while the temperatures of children remained stable. Comparisons of gastrectomy versus tympanoplasty groups indicated the operative site had little effect on the patient's body temperature. Patients who underwent a gastrectomy showed an average fall in esophageal temperature of 0.8 degrees C, where as there was an average temperature decline of 0.5 degrees C in tympanoplasty. Body temperature decrease was dependent on the duration of the operative procedure. The longer the procedure, the greater change in temperature. There was no significant difference between the effects of the volatile anesthetic agents on patient's body temperatures.

Malakoplakia is an uncommon granulomatous disease most frequently found in the bladder or ureter. Howevcr, it has been reyorted in almost every ather organ and structure, the colon is the most common site of malakoplakia outside the urogenital tract and colonic carcinoma is the most commonly associated disease. A case of malakoplakia of the colon in a 54-year-old female is reported. Sigmoidoscopy revealed multiple whiteyellowish nodules simulating polypoid lesion at 10cm from the anal verge. The biopsy showed characteristically comprised submucosal proliferations of histiocyte and chronic inflammatory cells with typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Intravenous pyelogram showed no evidence of involvement of the urinary system. These nodules were removed by endoscopic polypectomy, So far, this is the first case of isolated colonic malakoplakia in Korea.

Primitive neuroectodermal tumor (PNET) is a rare tumor derived from fetal neuroectodermal cells. These tumors occur in the central nervous system and peripheral locations, but the occurrence of primitive neuroectodermal tumors located in the uterus is extremely rare. We present a 53-year-old woman with primitive neuroectodermal tumor of the uterus confirmed by immunohistochemical staining. We have experienced one case of PNET of the uterus and wish to report with brief review of concerned literature.
