    Title Pediatric Single-port-access Nephrectomy for a Multicystic, Dysplastic Kidney.
    Date November 2009
    Journal Journal of Pediatric Urology

    Major urologic surgery via a single port has emerged as the latest progression in laparoscopy and robotics. While current literature highlights the single-port approach to the surgical treatment of cholecystitis, appendicitis and varicoceles, this technique has never been employed to perform a nephrectomy on a child. We herein report a case of a pediatric patient who underwent nephrectomy via single-port-access.

    Title Plasma Ghrelin Levels and Their Relationship with Gastric Emptying in Patients with Dysmotility-like Functional Dyspepsia.
    Date September 2009
    Journal Digestion

    Ghrelin affects gastric motility. However, little is known about the role of ghrelin in the pathophysiology of functional dyspepsia (FD). We investigated plasma ghrelin levels and their relationship with gastric emptying time in dysmotility-like FD patients.

    Title Seroprevalence of Toxoplasma Gondii Infection and Characteristics of Seropositive Patients in General Hospitals in Daejeon, Korea.
    Date July 2009
    Journal The Korean Journal of Parasitology

    To figure out the epidemiological status and relevance with other diseases in toxoplasmosis, we checked serum IgG antibody titers of 1,265 patients and medical records of seropositive patients. Seropositive rates were 6.6% by latex agglutination test (LAT) and 6.7% by ELISA. No significant differences were detected between sexes and age groups. The peak seroprevalence was detected in the 40-49-year-old age group. According to clinical department, Toxoplasma-positive rates were high in patients in psychiatry, ophthalmology, health management, emergency medicine, and thoracic surgery. Major coincidental diseases in seropositive cases were malignant neoplasms, diabetes mellitus, arthritis, chronic hepatitis B, chronic renal diseases, schizophrenia, and acute lymphadenitis, in the order of frequency. In particular, some patients with chronic hepatitis B and malignant neoplasms had high antibody titers. These results revealed that the seroprevalence of toxoplasmosis in a general hospital-based study was similar to that in a community-based study, and T. gondii seropositivity may be associated with neoplasms, diabetes, and other chronic infections.

    Title Effects of Specific Monoclonal Antibodies to Dense Granular Proteins on the Invasion of Toxoplasma Gondii in Vitro and in Vivo.
    Date December 2001
    Journal The Korean Journal of Parasitology

    Although some reports have been published on the protective effect of antibodies to Toxoplasma gondii surface membrane proteins, few address the inhibitory activity of antibodies to dense granular proteins (GRA proteins). Therefore, we performed a series of experiments to evaluate the inhibitory effects of monoclonal antibodies (mAbs) to GRA proteins (GRA2, 28 kDa; GRA6, 32 kDa) and surface membrane protein (SAG1, 30 kDa) on the invasion of T. gondii tachyzoites. Passive immunization of mice with one of three mAbs following challenge with a lethal dose of tachyzoites significantly increased survival compared with results for mice treated with control ascites. The survival times of mice challenged with tachyzoites pretreated with anti-GRA6 or anti-SAG1 mAb were significantly increased. Mice that received tachyzoites pretreated with both mAb and complement had longer survival times than those that received tachyzoites pretreated with mAb alone. Invasion of tachyzoites into fibroblasts and macrophages was significantly inhibited in the anti-GRA2, anti-GRA6 or anti-SAG1 mAb pretreated group. Pretreatment with mAb and complement inhibited invasion of tachyzoites in both fibroblasts and macrophages. These results suggest that specific antibodies to dense-granule molecules may be useful for controlling infection with T. gondii.
