Methanol and/or boiling water extraction of 201 natural products and subsequent MTT assay using MT-4 cell line was carried out to screen the anti-HIV-1 activity. Among 97 methanol extracts, 7 extracts from Chrysanthemi Indicium Flos, Magnoliae Cortex Machili Cortex, Reynoutriae Rhizoma, Lithospermi Radix Agastachis Herba, and Chaenomelis Fructus showed anti-HIV-1 activity and their SI value were 2.25 to 5.77. In addition, among 119 boiling water extracts, 10 extracts from Lonicerae Caulis et Foloium, Elsholtziae Herba, Leonuri Herba, Portulacae Herba, Schizonepetae Herba, Curcumae Rhizoma, Amomi Cardamomi Fructus, Cirsii Radix et Herba, Carpesii Herba, and Siegesbeckiae Herba showed anti-HIV-1 activity and their SI value were 1.30 to 7.64. Methanol extracts of above seven natural products were fractionated and the anti-HRs_1 activity of each fraction was examined. Extraction was carried out with hexane, chloroform, butanol, and water to trace active anti-HIV-1 componets. As a result, the water fraction of Magnoliae Cortex, Machili Cortex, Reynoutriae Rhizoma, Agastachis Herba, Chaenomelis Fructus and the butanol fraction of Chrysanthemi Indicium Flos, Reynoutriae Rhizoma showed anti-HIV-1 activity and their SI value were 1.40 to 8.02. We could reach a conclusion that studies to trace the anti-HIV-1 active component of each natural products in further Sractionation and to identify its structure by Infrared spectroscopy, NMR spectroscopy and gel permeation chromatography were needed.

Renal Infarction is a rare disease and in 90% of patients with renal infarction, underlying cardiac disease is presented. Most often this includes valvular heart disease, cardiac arrhythmias, rheumatic heart disease with fibrillation, or subacute bacterial endocarditis. The correct clinical diagnosis and appropriate treatment of renal infarction are often delayed. Three cases of renal infarction were presented with review of literature.

Spontaneous perirenal hematoma can occur during the course of a varied group of diseases. It is not a rare disease. The diagnosis is based on either the sudden or insidious onset of abdominal or flank pain, abdominal distention, the symptoms and signs of internal bleeding, and the appearance of a mass in either upper quadrant. The picture of the acute surgical condition of the abdomen is often seen. The treatment is surgery and prognosis depends upon the underlying disease, the degree of hemorrhage and the promptness of treatment. We experienced one case of spontaneous perirenal hematoma due to metastatic choriocarcinoma only to the perirenal fat, not renal parenchyme.

In the present study, we have tried to isolate and identify herpes simplex virus type 2(HSV 2) from clinical specirnens, which were inoculated into Vero cell line and grown. Eight strains of viruses were isolated from 20 suspected cases diagnosed from the pr ivate clinics in Seoul. Viruses isolated from 4 rnale and 1 female cases with active lesion were identified to the HSV 2 by indirect immunofluorescence using monoclonal antibody to HSV-2. In addition, morphology of the isolated viruses were observed under electron microscope.

To examine AZT resistance of HIV-1 isolates from AZT treated or untreated Korean, several biological characteristics such as syncytium formation, HIV-1 reverse transcriptase activity and the p24 antigen production in MT-2 cells infected with 4 HRT_1 isolates were determined. As controls, we tested HIV-1 HTLV-IIIB and pre-drug isolate as AZT susceptible strains, in addition to HIV-1 RTMC/MT-2 and post-drug isolate as AZT resistant strains. When the inoculum size of HIV-1 was 300 TCID50well and 100 TCID50/well, the AZT susceptibility of AZT untreated HIV-1 isolates 8806 and 9571 were similar to that of HIV-1 HTLV-IIIB and AZT-susceptible HIV-1 strains. When we evaluated AZT resistance of isolates HRs-1 8812 and 9113 treated with AZT for 36 months by observation of syncytium formation, HIV-1 8812 showed resistance simillar to that of HIV-1 RTMC/MT-2 strain forming syncytium up to AZT 1microgram/ml, and HIV-1 9113 showed resistance identical with that of AZT-resistant HIV-1 strain which formed syncytium up to AZT 10 microgram/ml. Especially, when we evaluated AZT resistance by HIV-1 reverse transcriptase activty and the p24 antigen production, HIV-1 isolates 8812 and 9113 showed much higher resistance (>10 - 200 fold) compared with HN-1 RTMC/MT-2 and AZT-resistant HIV-1 strain.

10.Clinical Strategies to Develop Transplantation Tolerance.

Hanyang Medical Reviews 2006;26(3):70-76
The development of immunosuprressants has had a significant influence on inhibition of acute allograft rejection. However, long-term graft survival has not been achieved by immunosuppressants, probably because of their nonspecific suppression of T cell activity and nonimmune side effects. The ideal way to overcome the limitations of current immunosuppressants is to induce allograft-specific immune tolerance. Transplant immunologists are exerting their efforts in achieving transplantation tolerance using four different approaches; costimulatory blockade, mixed hematopoietic chimerism, T cell depletion, and regulation by regulatory T cells. It is expected that transplantation tolerance will soon be established as a standard immunosuppressive regimen with little side effects in preventing and reversing allograft rejection.
