1.Upregulation of IP-10(CXCL10) mRNA Expression by Interleukin-18.
Yeungnam University Journal of Medicine 2007;24(1):67-78
BACKGROUND: Interleukin-18 (IL-18) is one of the principal inducers of interferon-gamma (IFN-gamma) in lymphocytes. MATERIALS AND METHODS: The effect of IL-18 on the expression of chemokine IP-10(CXCL10) mRNA in C57BL/6 mouse peritoneal macrophages was studied by using Northern blot analysis, enzyme linked immunosobent assay and electrophoretic mobility shift assay. RESULTS: IL-18 was determined to exert no direct effect on the expression of IP-10(CXCL10) mRNA. However, IL-18 pretreatment was determined to play a cooperative role in the synergistic induction of LPS-induced IP-10(CXCL10) mRNA expression. The effect associated with IL-18 pretreatment with regard to the synergistic induction of LPS-induced IP-10 (CXCL10) mRNA expression was detected after 16 hr of IL-18 pretreatment, administered prior to LPS stimulation. The pattern of NF-kB binding activity during IL-18 pretreatment with LPS stimulation was found to coincide with the expression of IP-10(CXCL10) mRNA. CONCLUSION: Although IL-18 alone exerts no direct effect on the expression of chemokine IP-10(CXCL10), a definite period of IL-18 pretreatment induces the synergistic expression of LPS-induced IP-10(CXCL10) mRNA. NF-kB activation is a component of this synergistic effect of IL-18 pretreatment. These results provide useful information, which may facilitate the elucidation of the action mechanisms underlying IL-18 effect on the expression of IP-10(CXCL10) mRNA.

We studied thirteen, all male, patients who had trans-scaphoid perilunar dislocation(stage I, 5 cases) and dislocation of lunate(stage IV, 8 cases). Age of patient was ranged from 25 years to 49 years(avr. 36 years)and the most common cause of injury was fall down(6 cases, 46%). Seven acute cases, diagnosed and treated within 3 weeks from injury, were treated by open reduction and K-wire fixation(5 cases), and K-wire fixation and bone graft(1 case) and Herbert screw for fracture of scaphoid(1 case). Six chronic cases diagnosed and treated after 3 weeks from injury were treated by open reduction and K-wire fixation(1 case), K-wire fixation and bone graft(1 case), removal of lunate(2 cases), and arthroplasty using muscle after removal of lunate(2 cases). Thirteen cases were followed up for average 33 months(from 13 months to 81 months). Grip power was evaluated as excellent or good in 8 cases and fair in 5 cases. Range of motion of wrist joint was decreased 21 degrees in flexion, 22 degrees in extension, 4 degrees in ulnar deviation, and 5 degrees in radial deviation of wrist joint, compared with uninjured side. Carpal height and carpal height ratio were decreased to 33.1 and 0.51, compared with normal 35.8(p=0.001) and 0.55(P < 0.001), respectively. Between 2 groups of acute and chronic cases, no significant differences were noted in carpal height or carpal height ratio. The surgical treatment of perilunar fracture-dislocation has not simple option, therefore, we would recommend the early diagnosis and exact anatomical reduction.

Plesiomonas shigelloides is known to cause diarrhea in human. It is a facultatively anaerobic gram-negative rod belonging to the family Vibrionaceae. We isolated P. shigelloides from two patients with diarrhea, a 62-year-old woman with steroid therapy and a 4-year-old boy with no predisposing factor. The organisms were isolated on enteric agars as a nonlactose fermenter and were identified by oxidase, indole, and other biochemical characteristics. The isolates were susceptible to commonly used antimicrobial agents with the exception of ampicillin. P. shigelloides infection is rarely reported in our country, but appears to be a significant cause of diarrhea that responds to antimicrobial therapy. Therefore we suggest the need for correctly identifying P. shigelloides.

4.Utility of Regular Radiological Follow-up on Early Detection of Contralateral Malignancy and Long-term Outcomes in Metachronous Bilateral Breast Cancer Patients.
Kosin Medical Journal 2017;32(1):72-83
OBJECTIVES: We investigated the utility of regular radiological follow-up on the early detection of contralateral breast cancer(CBC) and prognosis in patients with metachronous bilateral breast cancer. METHODS: Between 1983 and 2010, 49(2.1%) metachronous bilateral breast cancer patients were identified among a total of 2,343 cases of invasive or in situ breast carcinomas. We reviewed the patients' medical records including age, stage, duration between the first and second breast cancer diagnosis, operation method, recurrence, and breast cancer-specific survival. RESULTS: The mean ages at the first and second breast cancer diagnosis were 43.8 and 49.2 years, respectively. The mean duration between the first and second breast cancer diagnosis was 68.9 months (range, 7–266 months). Regular radiological follow-up with annual mammography(MMG) with or without ultrasonography was conducted in 28 patients (63.6%, Group 1), and no regular follow-up was performed in 12 patients (27.3%, Group 2). The median follow-up duration was 150 months. In a comparative analysis, Group 1 patients exhibited more stage 0 and stage 1 malignancies (82.1% vs. 25%, P =0.006) as second cancer and the same or an improved stage (71.4% vs. 33.3%, P =0.042) of second cancer compared to Group 2 patients. Breast cancer-specific survival rates between the two groups after the first cancer occurrence were higher in Group 1 patients compared to Group 2 patients, although this did not reach statistical significance. CONCLUSION: Screening for CBC with regular radiological follow-up could result in early detection of CBC, less invasive surgical procedures, and enhanced breast cancer-specific survival outcomes.

BACKGROUND: Family counseling is an essential part of family practice in which patients are cared in psychosocial dimension as will as in physical dimension and the family is dealt with as a whole unit. However, it is little applied in practice. The department of family medicine has made efforts to activate family counseling. This study was done to estimate the patients response on the effect of family counseling that we have performed, and to investigate what clinical problems counseling was held and in what situations the counseling was perceived to be useful by the patients. We hope this study will be useful to establish some useful data and ideas for the development of family counseling in family practice in Korea. METHODS: The subjects of this study are 53 households who received family counseling at the department of family medicine from Oct. 1, 1994 to May 31, 1995. 64 households received counseling during this peroid, but 11 persons who could not be reached by the phone were excluded. Patients demographic charateristics, patients chief complaints, physicians assessrnent on the complaints and major prolems presented in the counseling sessions were identified from the medical records. Patients own estimation of the effect of counseling and the reasons for termination of counseling were inquired through the telephone interview. Finally the association between the usefulness of counseling and some factors was statistically analyzed. RESULTS: Subjects were predominently women(84.9%), especially middle aged. The most common chief complaint was headache complained by 10 subjects (18.9%), and the second and the third were abdominal pain complained by 8 (15.1%) and chest discomfort complained by 7(13.2 %), respectively. The list of physicians assessment included depression(34.0%), physical symptom per se without any assessment(20.8%), family problem(15.1%), somatization(13.2%), and anxiety(9.45). More than half of the subjects(60.4%) had only one session, 26.4% two sessions and 7.5% more than 4 sessions. The most common problem presented in the counseling was marital conflict(28.3%), the second was trouble with in-laws(15.1%), and the third was chronic illness in the family(9.4%). 32.1% replied that the counseling was very helpful, 28.3% somewhat helpful, 17% little helpful, 20.8% never helpful, and 1.9% not sure. The session was experienced to be more useful in the group of duration of symptom less than 6 months, than in the group of longer duration(p<0.05), and in the group with motivation for counseling than in the group without motivation(p<0.05). CONCLUSIONS: About 60% of subjects replied the counseling was useful to them. Symptom duration and patients motivation to participate in counseling showed significant association with the effect of family counseling.

Korean Journal of Clinical Pathology 1997;17(6):1137-1143
BACKGROUND: It has been known that blood group antibodies are not produced in the neonatal period and that if the antibodies exist, they are probably maternal in origin which had crossed the placenta. There have been several studies conducted abroad on when these antibodies are formed but none has been done in Korea. This study was carried out to determine the ABO blood type and blood group antibodies in children from neonates up to 5 year old. We hoped to determine when and in what pattern blood group antibodies were produced. METHODS: We selected 337 children from neonates up to 5 year old who were admitted to Hanyang university Hospital in Seoul or Kuri from 1994 to 1996. Cell typing was done immediately by the slide method. The anti-A and anti-B used for cell typing were supplied by Immucor (Norcrosis, Ga) . Sera were stored at -70 degrees C until they were tested for ABO blood group antibodies by the standard saline test tube method. When uncertain results were obtained, a drop of the mixture was placed on a slide and observed under a microscope. RESULTS: ABO blood group antibodies were detected in 9 of 50 (18%) infants less than 1 week old and in 10 of 51 (20%) infants between 1 week and 3 months of age. The pattern of ABO blood group antibody production was similar to that of the fetal period up to 3 months after birth, after which antibody production increased rapidly to reach approximately 80% at 6 months of age, There was no difference in ABO antibody production between boys and girls. The antibody formation pattern of group A and group B infants less than 6 months of age showed anti-A to be 35% and anti-B to be 20%. In group O infants of the same age, anti-A was positive In 42% and antral-B In 33%. However, after 6 months of age, there was no difference in antibody production among groups A, B, or O. CONCLUSIONS: Antibodies directed toward ABO antigens were detected in 19 out of 101 (19%) infants less than 3 months old. We therefore believe it is necessary to Perform serologic typing as well as cell typing in these Infants. Furthermore, the emergency transfusion of type A or B blood to a type O infant under the impression that anti-A and anti-B do not exist should be forbidden.

Journal of Korean Academy of Nursing 2008;38(2):187-194
PURPOSE: This study was to identify behaviors preventing the recurrence of breast cancer and the level of quality of life. METHODS: This descriptive study was conducted using a structured questionnaire from November 1, 2006 to December 25, 2006 . One hundred and twenty two women breast cancer survivors were recruited by convenience sampling. RESULTS: The most frequent behavior for preventing recurrence of the breast cancer was dietary treatment (90.9%) and exercise (86.8%) was the second behavior. In addition, most of them perceived these behaviors as 'very effective' (82.8%). The degree of the quality of life of a breast cancer survivor was 5.34 point indicating a 'medium level'. CONCLUSION: Breast cancer survivors pursued various behaviors for preventing recurrence of breast cancer. Therefore, the nursing interventions should be focused on a systematic educational approach considering healthy behaviors to prevent breast cancer recurrence for breast cancer survivors.

In order to evaluate the possible roles of secretory proteases in the pathogenesis of amoebic keratitis, we purified and characterized a serine protease secreted by Acanthamoeba lugdunensis KA/E2, isolated from a Korean keratitis patient. The ammonium sulfate-precipitated culture supernatant of the isolate was purified by sequential chromatography on CM-Sepharose, Sephacryl S-200, and mono Q-anion exchange column. The purified 33 kDa protease had a pH optimum of 8.5 and a temperature optimum of 55 degrees C. Phenylmethylsulfonylfluoride and 4- (2- Aminoethyl) -benzenesulfonyl-fluoride, both serine protease specific inhibitors, inhibited almost completely the activity of the 33 kDa protease whereas other classes of inhibitors did not affect its activity. The 33 kDa enzyme degraded various extracellular matrix proteins and serum proteins. Our results strongly suggest that the 33 kDa serine protease secreted from this keratopathogenic Acanthamoeba play important roles in the pathogenesis of amoebic keratitis, such as in corneal tissue invasion, immune evasion and nutrient uptake.
