  • Phyllanthus urinaria was an important species in Korea and distributed in all around of Korea. The roots and stems of this plant have been used for natural medicine for the treatment of diabetes, the hepatitis B virus and disturbances of the kidney and urinary bladder. Production of adventitious roots in P. urinaria by in vitro cultures could be used as alternatives materials. Shoot and root segments from P. urinaria seedling were cultured on Murashige and Skoog (MS) medium supplemented with 3.0 mg/L IBA and 30 g/L sucrose. After 4 weeks of culture, the highest induction of adventitious roots was obtained from the shoot part. Frequency of adventitious root formation on medium with various kinds of auxins (IAA, NAA, 2,4-D, and IBA) and various concentrations of IBA (0, 0.1, 0.5, 1.0, 3.0, and 5.0 mg/L) was tested. The maximun induction of adventitious root was obtained on medium with 0.5 mg/L IBA. In liquid culture, growth of root was best on medium supplemented with 30 g/L sucrose. Adventitious roots were cultured in 5 L bioreactor containing 1/2 MS medium supplemented with 0.5 mg/L IBA and 30 g/L sucrose and mass-production of adventitious roots was successfully achieved. These results revealed the first attempt for the production of adventitious roots in P. urinaria.

  • Pumpkin seed oil (PSO) was investigated for its parasite elimination activity and efficacy in treating disorders of the prostate gland and urinary bladder. We confirmed the composition of PSO and identified its ability to improve vessels. Gas chromatography coupled with mass spectrometric (GC-MS) system was used for PSO composition analysis. Cytotoxicity and cell proliferation were confirmed by Cell Counting Kit-8 (CCK-8) assay. Nitric oxide(NO) production was measured with Griess reagent, and intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 mRNA expression levels were measured by reverse transcription polymerase chain reaction (RT-PCR). As a result, PSO revealed the presence of several components such as linoleic acid, oleic acid, palmitic acid and stearic acid. Cytotoxic effects of PSO were not observed, and PSO increased nitric oxide production in human umbilical vein endothelial cells (HUVEC). Additionally, TNF-${\alpha}$-induced cell proliferation and ICAM-1 expression in HUVEC were inhibited by PSO treatment, whereas VCAM-1 expression was not significantly reduced. Taken together, these results show that PSO is worthy of study as a candidate food material for improvement of vascular disease.

  • Xanthogranulomatous (XG) inflammatory disease is a rare benign disease involving various organs, including the gallbladder, bile duct, pancreas, spleen, stomach, small bowel, colon, appendix, kidney, adrenal gland, urachus, urinary bladder, retroperitoneum, and female genital organs. The imaging features of XG inflammatory disease are nonspecific, usually presenting as a heterogeneous solid or cystic mass. The disease may also extend to adjacent structures. Due to its aggressive nature, it is occasionally misdiagnosed as a malignant neoplasm. Herein, we review the radiological features and clinical manifestations of XG inflammatory diseases in various organs of the abdomen and pelvis.

  • Purpose : Treatment of choice for uterine cervix cancer stage IIB is radiotherapy. We analyzed survivals, Prognostic factors, patterns of failure and complications. Materials and Methods : This is a retrospective analysis of 167 patients with stage IIB carcinoma of uterine cervix treated with curative external pelvic and high dose rate intracavitary radiotherapy at the Department of Therapeutic Radiology, Soonchunhyang University Hospital from August 1985 to August 1994. All the patients followed up from 3 to 141 months(mean 60 months) and age of patients ranged from 31 to 78 years at presentation(mean : 55 years). Results : Overall complete response rate was $84\%$. The response rate for squamous cell carcimoma and adenocarcinoma were $86\%$ and $60\%$, respectively. Overall 5-years survival rate and disease free survival rate was 62 and $59\%$, respectively Mass size and treatment response were significant Prognostic factors for survival Pathologic type and parametrial involvement were marginally significants Prognostic factors. Local failure was 43 cases, distant metastasis was 14 cases and local failure plus distant metastasis was 3 cases, and most of local failures occurred within 24 months, distant metastasis within 12 months after treatment Twenty eight($16.8\%$) patients developed late rectal and urinary complications There were tendency to increasing severity and frequency according to increased fractional dose and total(rectal and bladder) dose. Conclusions : Survival rate was significantly related to tumor size and radiotherapy response. Tumor size should be considered in the clinical s1aging. To increased survival and local control, clinical trials such as decreasing duration of radiotherapy or addition of chemotherapy is needed. To detect early recurrence, regular follow up after RT is important. Because total rectal and bladder dose affected late complications. meticulous vaginal packing is needed to optimize dose of normal tissues and to decrease late complications.
