Anthrax in man is usually cutaneous, resulting from contact with materials derived from infected livestock. Internal organs are infrequently involved,. This report concerns a case of primary anthrax of intestine. The first case of primary anthrax of intestine is to our knowledge in Korea. The patient was a 14-year-old male who has complained of nausea, vomiting and acute abdominal pain. History was otherwise noncontributory except for ingestion raw meat of the dead cattle, one day before the onset of the disease. The cattle presumably died due to Bacillus anthracis in a village Bae-Ban Dong in the city of Kyung ju, Kyung Pook. Among 15 sufferers, 2 cases died 3 days later. Bacillus anthracis isolated from the raw beef, blood samples of two patients and throat culture of one patient. At laparotomy, the peritoneal cavity was full of serosanginous fluid. Right hemicolectomy including partial resection of ileum was done. The bowel was segmentally dilated, hemorrhagic and necrotic, especially at terminal ileum. The mucosa was edematous and largely ulcerated covered with greenish yellow exudate. The intense vascular congestion with hemorrhage and numerous colonization of bacteria were present through the entire wall. The organisms were large, gram-positive and PAS-negative bacilli in long chain. Bacterial emboli were scattered in lymphatics. The other feature was band like lymphoid cell infiltration in ulcer base and submucosal layer. Payer's patches were prominent and the germinal centers were necrotic. Interfollicular spaces exhibited aggregates of numerous atypical lymphoid cells. The cells were five times larger than resting lymphocytes and had several prominent nucleoli and abundant amphophilic cytoplasm. On immunohistochemical staining, most of atypical cells were positive for T-cell marker and Ki-I Ag. The mesenteric lymph nodes were enlarged, showing reactive feature, and the atypical cells were also demonstrated. The patient recovered completely.

BACKGROUND: The use of autologous transfusion is gradually increasing since it eliminates transfusion-transmitted viral diseases, and avoids the risk of alloimmunization of red blood cells and posttransfusion graft-versus-host disease. The majority of premature neonates born at less than 1500 g need one or more red blood cell transfusion during the hospitalization and cord blood is considered as the most ideal blood for neonate autologous transfusion. In order to evaluate the adequacy of stored cord blood for autologous transfusion for neonates, the levels of plasma free hemoglobin, red blood cell adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG) were measured at the time of collection, and then a week interval by 4 weeks. METHODS: The cord blood was collected in a single donor bag with CPDA-1 by aseptic technique from 28 newborns, stored for 28 days at 4degrees C, and changes in the levels of plasma free hemoglobin, red blood cell ATP and 2,3-DPG were measured at the time of collection, and then a week interval by 4 weeks for 26 cord bloods which were not presented with any bacterial growth during the storage. RESULTS: At the time of sampling, hemolysis was 0.11+/-0.16%, and intracellular ATP and 2,3-DPG were 3.74+/-0.99 mumol/g Hb and 11.67+/-1.21 mumol/g Hb, respectively. During the storage, hemolysis gradually increased to 0.61+/-1.09% on 28 days (p<0.05). ATP gradually decreased to 2.98+/-0.92 mumol/g Hb (80% of initial level) on 28 days(p<0.05). The levels of 2,3-DPG were 4.20+/-0.87 mumol/g Hb (about 35% of initial level) on 7 days(p<0.05) and 1.16+/-0.74 mumol/g Hb (less than 10% of initial level) on 28 days (p<0.001). CONCLUSIONS: In conclusion, ATP and 2,3-DPG levels of cord blood that are related to the viability of red blood cells during the storage were similar to those of adults. Thus the cord blood appeared to be an appropriate source for neonate autologous transfusion, however, more intensive studies on the effects of 2,3-DPG and metabolic products in vivo are necessary since physical conditions and physiology of the red blood cells in the neonates are different in many aspects from those of adults and children.

Mutations in the tumor suppressor p53 gene are the most frequently observed genetic lesions in human cancers. It seems that wild type p53 does significant role on growth and differentiation of normal cells, Mutations and allelic loss of the p53 gene are thought to be a cause of tumor development and to be correlated with the prognostic factors in various human cancers such as breast, ovary and lung cancer. Mutant p53 proteins have a prolonged half-life and can be detected by immunohistochemistry. In case of GTD(gestational trophoblastic disease), although the mutation of p53 gene mutation was revealed to be very rare, the overexpression of p53 in immunohistochemical staining has been reported in wide range of discrepancy and its role or prognostic significance in GTD is uncertain. This study is performed to define the status of p53 overexpression in GTD and to evaluate the correlations between p53 overexpression and prognostic factors of GTD. THE RESULTS WERE AS FOLLOWS: 1. p53 overexpression was detected in none of normal placental tissue, in 58.3%(14/24) of hydatidiform mole, in 15%(6/8) of invasive mole, in 75%(3/4) of choriocarcinoma, and in 100%(1/1) of placental site trophoblastic tumor, and showed significant difference between normal placenta and GTD. We could not find any difference of the p53 overexpression between benign group(H-mole) of GTD and malignant one(invasive mole, choriocarcinoma, and placental site trophoblastic tumor) 2. In H-mole, low-risk group showed significantly higher prevalence of p53 overexpression than high-risk group did. In malignant group, there is no difference in the prevalence of p53 overexpression between early(FIGO stage I) and late(II- IV)stage-diseases, but the prevalence of p53 overexpression of low-risk group is slightly higher than that of high-risk group although we failed to find statistical significance. In conclusion, the high prevalence of p53 overexpression in GTD suggests that p53 may have a certain role in the pathogenesis of GTD or at least represent generalized DNA damage or genetic instability of GTD. And the higher prevalence of p53 overexpression in low-risk group suggests that accumulation of wild-type p53 may be related with favorable prognosis in GTD.

PURPOSE: The diagnosis of hypertrophic pyloric stenosis(HPS) can be made by clinical manifestations and upper gastrointestinal(UGI) series in most cases. Recently, the ultrasonogram(US) is a more accurate and reliable method for the diagnosis of HPS in early stage. METHODS: We retrospectively studied 27 HPS patients confirmed surgically from January 1999 to March 2000. We reviewed clinical histories and physical and laboratory findings. Among these patients, ultrasonograms were carried out in 23 cases preoperatively. Therefore, we analyzed pyloric muscle thickness(PT), pyloric diameters(PD), and pyloric canal lengths(PL), and calculated pyloric volume(PV) by the equation of 'PV=pie(1/2PV)2xPL'. RESULTS: The mean age on admission was 39.0+/-20.4 days and 70.4% of the patients were under 6 weeks of age. The mean age at onset was 26.9+/-20.4 days and the duration of symptoms was 12.7+/-11.6 days. On physical examination, the pyloric tumors were palpated in 14 cases(51.9%) and the gastric peristalses were noted in 8 cases(29.6%). UGI series were carried out in 21 cases, and all of them had the characteristic findings of HPS. The mean PT was 5.23+/-1.05mm, the mean PD wase 13.56+/-2.25mm, the mean PL was 21.42+/-3.85mm, and the calculated PV was 3.23+/-1.35 mL. According to the criteria by Stunden, et al., PT(>=4mm), PD(>=12mm) and PL(>=15mm) were satisfied in 91.3, 73.9 and 91.3% respectively. The PV(>=1.4mL) was satisfied in 95.7% according to the criterion by Westra, et al. CONCLUSION: The US in the diagnosis of HPS is safe and useful. With measurements of PV parameter, the diagnosis by US will be more reliable and more accurate.

Colorectal cancer remains the fourth most common malignancy in Korea, and has been ranked as the third leading cause of cancer deaths in 2020. This study aims to describe the epidemiologic status of colorectal cancer in Korea, and provide basic data for effective primary and secondary prevention methods by summarizing risk factors and screening tools.Current Concepts: Although colorectal cancer incidence and mortality have decreased in recent years in Korea, it still poses a significant public health burden. From the early 1990s until the mid-2000s, the 5-year relative survival of patients with colorectal cancer in Korea continuously increased. This can be attributed to the successful introduction of the government-led screening program; development of improved surgical techniques, anticancer drugs, and adjuvant treatment; and advances medical resources and infrastructure along with economic growth. However, since the late 2000s, the improvement in survival has stagnated. The coronavirus disease 2019 outbreak has reduced hospital visits and screenings, which is assumed to cause delays in diagnosis, leading to a worse prognosis in the patients. To overcome these obstacles, it is essential to explore modifiable environmental risk factors and appropriate screening test methods in Korea.Discussion and Conclusion: Primary prevention through risk factor modification and secondary prevention using suitable screening programs can reduce the incidence and mortality rates of colorectal cancer.

OBJECTIVE: To assess the relationship between vaginal cytology and bone mineral density in postmenopausal women. METHODS: In 93 postmenopausal women, vaginal cytology smears were taken for maturation index, serum estradiol level and bone mineral density were also taken. the percentage of each cell type found By vaginal cytology was multiplied to its specific value:superficial cells, 1.0; intermediate cell, 0.6; parabasal cell, 0.2 and modified to maturation value. Bone mineral density was measured at lumbar spine using DEXA. RESULTS: The mean bone mineral density was 0.88+/-0.14g/cm2. Mean maturation value was 50.53+/-20.74 and it was related with age and bone mineral density. CONCLUSION: Maturation value of vaginal epithelial cell represents the influence of estrogen on bone mineral density.

BACKGROUND: This study was undertaken to determine temporal changes in expression of various genes and the effect of platelet-activating factor antagonist on their expression. SUBJECTS AND METHODS: The changes in expression of various genes including interleukin-1, iNOS, TNF-alpha, ICAM-1, cPLA2, GLUT1, BDNF and Bcl-X according to time were examined using reverse-transcription polymerase chain reaction(RT-PCR) by checking at various time points after induction of middle cerebral artery(MCA) occlusion in the thrombotic and embolic models of stroke of Sprague-Dawley rats. We also examined the effect of pretreatment of a PAF antagonist, BN52021 on the expression of the same genes by RT-PCR and by in situ hybridization technique. RESULTS: The expressions of BDNF, IL-1, GLUT1, iNOS, cPLA2 and TNF-alpha were increased in ischemic brain tissue. However, the temporal profiles of their expression were variable; the peak expression was observed after 1 hour reperfusion in TNF-alpha, after 4 hours in IL-1, cPLA2 and BDNF and after 24 hours in GLUT1 and iNOS. Pretreatment of a PAF antagonist, BN52021, significantly inhibited the ischemia-induced expression of TNF-alpha, cPLA2 and iNOS without affecting the expression of the BDNF and GLUT1. In situ hybridization showed that cPLA2 expression induced by transient forebrain ischemia in dentate gyrus was ameliorated by the pretreatment of BN52021. CONCLUSION: This result indicates that BN52021, PAF antagonist, specifically inhibits expression of certain genes, which may be related to its protective effect on ischemic brain injury.
