PURPOSE: Low urinary pH is a risk factor for uric acid stones, and acidic urine has been described as a renal manifestation of the metabolic syndrome. We evaluated the association between metabolic syndrome and urinary pH in adult Korean men who visited a health promotion center. MATERIALS AND METHODS: From 2004 to 2008, a total of 18,513 adult men who visited our health promotion center were enrolled in this study. The relation between urinary pH and various parameters associated with the metabolic syndrome were evaluated. RESULTS: The average age was 45.6 years (range, 18-95 years), and 4987 men (26.9%) were classified as having the metabolic syndrome. The mean urinary pH of the metabolic syndrome group was 5.91, which was significantly lower than that of the normal group (6.08). In univariate and multivariate analysis, body mass index, serum triglyceride, and blood sugar were negatively correlated with urinary pH (p<0.05). In multivariate logistic regression analysis, obesity (body mass index > or =25 kg/m2), hypertriglyceridemia (> or =150 mg/dl), high fasting glucose (> or =110 mg/dl), and low high-density lipoprotein cholesterol (<45 mg/dl) were the significant factors that predicted low urinary pH (< or =5.5). CONCLUSIONS: Metabolic syndrome was related to lower urinary pH in ostensively healthy adult Korean men. Further studies are needed to elucidate the exact mechanism responsible for the lower urinary pH in individuals with the metabolic syndrome.

PURPOSE: hear stress (SS) and cyclic strain (CS) influence the expression of membrane type 1-matrix metalloproteinase (MT1-MMP) in microvascular endothelial cells (MVECs). It is known that changes in the level of Sp1 phosphorylation are important for MT1-MMP expression following SS and CS. However, the exact mechanism underlying this process is poorly understood. The aim of this study was to determine the effect of PKCzeta on serine phosphorylation and activation of Sp1 in response to SS and CS. METHOD: MVECs were exposed to SS or CS for up to 8 hours with or without PKCzeta inhibitors. The activity and phosphorylation of Sp1 were assessed by Western blot analysis and immunoprecipitation. MT1-MMP protein expression was assessed by Western blot analysis. RESULT: PKCzeta was phosphorylated and activated under SS, whereas no significant changes were noted under CS. SS increased Sp1 phosphorylation in a time-dependent manner, but no changes in the Sp1 phosphorylation were observed when the MVECs were pretreated with the PKCzeta inhibitors. By contrast, MVECs exposed to CS in the presence or absence of PKCzeta inhibitors showed no change in the phosphorylation of Sp1. SS decreased MT1-MMP protein expression in a time-dependent manner, but in the presence of PKCzeta inhibitors, MT1-MMP expression was not changed compared with the static levels after SS. CS increases MT1-MMP expression in a time-dependent manner. Similar expression was observed when the cells were pretreated with PKCzeta inhibitors under CS. CONCLUSION: These data demonstrate that the increased affinity of Sp1 for the MT1-MMP's promoter site occurs because of PKCzeta induced phosphorylation of Sp1 in response to SS.

PURPOSE: A prospective, controlled trial was conducted to evaluate growth, bone mineralization, and nutritional status receiving preterm human milk supplemented with a newly formulated Maeil human milk fortifier. METHODS: Twenty five fortified human milk-fed and preterm formula-fed infants with a birth weight < 1, 800 g and gestational age <35 weeks, who were born at Ajou University Hospital from March, 2003 through August, 2004 were studied. Growth, biochemical indices of bone mineralization, feeding tolerance, morbidity and wrist X-ray were assessed serially. Total body bone mineral density was measured by dual energy X-ray absorptiometry at 2 and 5months of age. RESULTS: There were no differences in growth, including weight, height and head circumference, between two groups. Serum Ca, P, ALP and other biochemical indices were similar. Although low grade rickets (grade I and II) were occasionally found on wrist X-ray, the rate of occurrence and severity were similar. The bone mineral densities of both group showed no difference. CONCLUSION: The fortified human milk-fed infants and preterm formula-fed infants showed no difference in growth, and bone mineralization. This newly formulated Maeil human milk fortifier can be safely used in preterm infants.

Ectopia cordis is defined as a congenital malposition of the heart partially or completely outside the thorax and often associated with sternal and congenital heart defects:surgical repair is generally unsuccessful because of the magnitude of the deformity and the associat-ed intracardiac anormalies. Four types of ectopia cordis are described : cervical, thoracic, abdominal and thoracoa- bdominal. Cervical and thoracic type are often fatal within days, because the heart is expo- sed and malformed. Abdominal type carries a better prognosis because cardiac abnormalities are less often found. The prognosis of thoraco-abdominal type mainly depends on the pre- sence of intracardiac abnormalities. We have experienced a case of thoracic ectopia cordis at 25 weeks' gestation by ultra- sonography, so present the case and the review with literature briefly.

PURPOSE: There are several ways of treating for right colon diverticulitis, based on its complications or location. The kind of operation emplolyed with cecal diverticulitis is still controversial, due to its similar symptoms to those of acute appendicitis, and is usually diagnosed during an appendectomy. This study is an analysis of 65 patients, which we experienced over the past 10 year, with right colon diverticulitis. METHODS: The hospital records of 65 patients with right colon diverticulitis, between January 1991 and January 2001, from the Catholic University School of Medicine, St. Paul's Hospital department of surgery were retrospectively reviewed. We analyzed the clinical data and outcomes, according to three different types of operation. RESULTS: The male to female ratio of the patients was 1.4:1, with a mean age of 36.8, ranging from 14 to 81 years. The most common manifestation was abdominal pain and tenderness (100%). Of the 65 cases, 53 underwent a diverticulectomy and an appendectomy, 5 a right hemicolectomy or an ileocecetomy and 7 an appendectomy only. The most common location of the diverticulum was cecum (62 cases), and the majority were single diverticulum (62 cases). There were complications in 4 cases (6.1%) following the operation, but their symptoms were mild. The complication rates in the diverticulectomy and appendectomy and appendectomy only groups were 5.6 and 14.2% respectively. However, there were no significant differences in the complication rates among 3 groups. There was no recurrence in the group with a right hemicolectomy or ileocecectomy, or in the group with a diverticulectomy and an appendectomy. The recurrences in the appendectomy only group were significantly higher than the groups, with 3 (42.8%) out of 7 cases (P=0.001). CONCLUSION: We suggest that an operation may be the primary safe treatment of right colon diverticulitis and that a diverticulectomy and an appendectomy may be reasonable operative methods that decrease the recurrence and morbidity of right colon diverticulitis.

Mesocolic hernias are rare congenital anormalies resulting from abnormalities in the intestinal rotation during embryonic development, and comprise approximately 53% of all congenital internal hernias. A right mesocolic hernia is formed by the arrest of further rotation of the prearterial segment of gut in the right side of the abdomen, with continued rotation of the postarterial segment, during the second stage of embryonic intestinal rotation, leading to the entrapment of almost the entire small bowel behind the right colonic mesentery. The condition may be discovered incidentally during at laparotomy, or may be the cause of an acute small bowel obstruction. Cecal diverticulitis is a rare disease, whose symptoms are similar to acute appendicitis. It is difficult to diagnose the two diseases accurately prior to operation. We report on a 48-year old man, who had perforated cecal diverticulitis and an incidental right mesocolic hernia, with a review of the literature.

Choledochocele is a rare cystic dilatation of the distal common bile duct in the wall of the duodenum. It is a type III choledochal cyst among the five types according to Todani's modification of the Alonso-Lej classification, and this type lll cyst comprises less than 4% of all choledochal cysts. We experienced one case of choledochocele in a 41-year-old woman who presented with recurrent pancreatitis, and we report on this case, along with a review of the literature.

The goal of this study was to examine the characteristics of the histo- immunological changes following induction of autoimmune prostatic inflammation achieved by subcutaneous allograft injection of the tissue homogenate of mouse ventral prostate. We also investigated the effect of the administration of androgen upon the development of mouse autoimmune prostatitis. Eight week old male C57BL/6 mice were selected and the presence, location and the degree of inflammation were identified after injection. The extent of infiltrations of the inflammatory cells in the prostate following the administration of the exogenous testosterone, the variation of the CD4/CD8 ratio of splenic lymphocyte and the variations of the interleukin-2 and tumor necrosis factor-alpha secreted by the splenic cells were also examined. The autoimmune prostatitis of the mouse induced by subcutaneous allograft injection of the mouse ventral prostate showed histological findings similar to that of human. The degree of induction was in proportion to the amount of tissues injected and showed organ-specificity. Exogenous administration of testosterone resulted in partial inhibitory effect on the induction of inflammation which was thought to be related to the decrease in the CD8+ T lymphocyte count and the functional inhibitory effect of the splenic T lymphocyte on the production of Interleukin- 2. However, tumor necrosis factor-alpha is presumed to be not closely related to the inhibitory effect of the administration of testosterone. In the future, further studies on the variation of cytokine levels and the value of sex hormones within the prostate and, moreover investigations in related to the humoral immune mechanism should be encouraged.
