PURPOSE: Na+-K+ ATPase Activity has beem estimated by the degree of inhibition of cation transport by cardiac glycosides (ouabain) using Rb-86 as a substrate. The biological characterist-Isc of T1-201 is known to be simiIar to those of potassium as a transport substrate in the presence of glucose, insulin or phobol myristate acetate (PMA). The purpose of this study was to measure ouabain sensitive Na+-K+ ATPase activity using T1-201 and compare with that using Rb-86. MATERIALS AND METHODS: Smooth muscle cells isolated from rat aorta or human placental umbilical artery were cultured, and used to measure cellular Na+-K+ ATPase activity. Na+-K+ ATPase activity was measured as a percentage decrease in cellular uptake of T1-201 or Rb-86 by ouabain under the presence of glucose, insulin or PMA in media. RESULTS: Na+-K+ ATPase ase activity measured with T1-201, as a transport substrate, was not different from those measured with Rb-86 in rat or human smooth muscle cell preparation. Incubation with high concentration glucose resulted in about 30% decrease in enzyme activity. In contrast, insulin or PMA resulted in 50-70% or 28% increases from baseline activity, respectively. CONCLUSION: These results suggests that T1-201 could replace Rb-86 in measurement of ouabain sensititive Na+-K+ ATPase activity in vitro. High level of glucose concentration decreased cellular Na+-K+ ATPase activity, but insulin or PMA increased it.

Mayer-Rokitansky-Kuster-Hauser Syndrom is characterized by the absence of the vagina and the uterus, the presence of apparently normal tubes and ovaries, feminine appearance, normal female secondary sexual characteristics, a normal 46, XX karyotypes, and a feminine psychosexual orientation. Absence of the vagina results from an embryological arrest in the development of the lower portion of the Mullerian system. Various methods of surgical treatment for the vaginal absence in this syndrom have been introduced but the ideal method to restore the original dimension and function of the normal vagina was not found. The two cases reviewed in this paper were all treated with modified McIndoe operation using full thickness skin grafts. Postoperatively both women were satisfied without complications, i,e. lack of skin graft, bleeding, urethrovaginal fistula, perforation of the rectum, rectovaginal fistula and significant vaginal stricture. This paper reveals the satisfactory results that were uniformly good.

OBJECTIVE: The purpose of this project was to suggest guidelines for management of Low grade Squamous Intraepithelial Lesion(LSIL) by evaluating natural course of LSIL of the uterine cervix. MATERIAL & METHODS: Among the women who visited Korea University Kuro Hospital from Jan. 1993 to Oct. 1998, One hundred fifty eight patients who were diagnosed as LSIL with colposcopy directed biopsy were followed up by colposcopy and/or cytology, HPV DNA test every 3 months. RESULT: In I58 patients who were diagnosed as LSIL, colposcopic examination confirmed progression to high grade intraepithelial lesion(HSIL) in 17(10.7%) patients, persistence of LSIL in 87(55%) patients, regression to normal in 54(34.2%) patients during the 3 year follow-up period. In prediction of LSIL subgroup, abnormal Pap test is 39%, 64%, 71% and abnormal HPV test is l6%, 29%, 65% in regression, persistent and progression group respectively. The shortest time of transition from minor lesion(LSIL) to high grade lesion was 12 months (the range, 12-51). CONCLUSION: Of the patients who were diagnosed as LSIL and monitored by colposcopy for 60 months, 34% had disease that regressed, 55% had persistent disease, and 11% had progressive disease. HPV DNA test(p=0.002) is more informative than pap test(p=0.567) in prediction of disease progression.

Familial hemophagocytic lymphohistiocytosis (FHL) is a rare disease characterized by fever, hepatosplenomegaly, cytopenia and non-malignant lymphohistiocytic infiltration with hemophagocytosis in reticulendothelial organs. We experienced three cases of FHL in identical male twins and their younger brother who presented with fever and severe hepatosplenomegaly. Cytopenia, elevated serum transaminase and low serum albumin levels, hypertriglyceridemia were common laboratory findings of them. One of them showed markedly decreased phytohemagglutinin induced lymphocyte proliferation and reversed CD4/CD8 ratio (0.52) in flowcytometric lymphocyte subset analysis. Aspirate of bone marrow revealed typical features consistent with FHL in two of them. In spite of recent therapeutic approaches, none of them survived.

BACKGROUND: This is a retrospective, descriptive study, evaluating the observed agreement between 1996 & 2002 Centers for Disease Control and Prevention (CDC) definitions of nosocomial pneumonia (NP) for medical intensive care unit (MICU) and surgical intensive care unit (SICU) patients. METHODS: A total of 476 adult patients who were over 15 years of age and had been admitted to the MICU & SICU of a university hospital between August 1, 2005 and August 1, 2007 were enrolled. Data were collected from electronic medical records according to the 1996 & 2002 CDC definitions of NP. RESULTS: According to the 1996 CDC definitions of NP, there were a total of 116 NP cases and incidence rate was 11.6 per 1,000 patient-days; when analyzed with the 2002 CDC definitions of NP, 75 cases met the criteria and the incidence rate was 7.5 per 1,000 patient-days. Kappa value measuring agreement between the two definitions was 0.67 (95% confidence interval 0.601-0.706). When 1996 CDC definitions were compared with 2002 CDC definitions, sensitivity, specificity, positive predictive value, and negative predictive value were 93.3, 88.5, 60.3, and 98.6%, respectively. CONCLUSION: Even though the aforementioned NP criteria had been applied to the same study population, the number of patients that met the definitions changed depending on which criteria had been used. Therefore, it is necessary to consider the differences when making a comparison.

Recently developed flow diverters, such as the pipeline embolization device (PED), allow for safe and efficacious treatment of giant intracranial aneurysms, with high occlusion rates and a low incidence of complications. However, incomplete obliteration after PED treatment may lead to aneurysm regrowth and delayed rupture. Herein, we report a case of a partially thrombosed giant aneurysm of the cavernous internal carotid artery that showed progressive recanalization at 1–3 months after application of a PED. We monitored inflow volume in the aneurysm by computed tomographic angiography (CTA) and computed tomographic volumetric imaging (CTVI). Based on the imaging results, rather than applying additional PED, we decided to make the switch from a dual antiplatelet medication to low-dose aspirin alone at 3 months after the treatment; complete obliteration of the aneurysm was noted at 21 months. Similar to the findings in this unusual case, CTA and CTVI may be useful follow-up methods for optimal management of patients with giant intracranial aneurysms after PED treatment.
