Three cases of spondyIolysis were experienced and treated by anterior interbody fusion of the involved spines at the department of orthopaedic surgery in the Taegu Hospital One case was accompanied with severe lumbago with radiating pain and other two cases with lumbago significantly. Review of literature was done with report of three cases of spondylolysis.

The gag encoded p24 protein of human immunodeficiency virus-1 (HIV-1) is a major constitutent of the viral core, and is also known as one of the most immunodominant antigens in the host immune response against the HIV-1. Based on the neutralizing ability of anti-p24 antibodies as well as their rapid appearance in human serum after viral infection, the development of vaccines and diagnostic tools targeting the p24 protein and anti-p24 antibodies is of great interest. For the characterization of the immunological properties of the HIV-1 p24 protein, in a previous study, putative B-cell epitopes were identified by screening the reactivity of a goat anti-p24 antiserum to a large array of overlapping synthetic peptides covering the whole p24 sequence. Four peptides were identified for their abilities to elicit a strong B-cell response, which sequences comprises the regions p24 (164-182), (202-221), (217-236) and (232-256), respectively. In the present study, the immunogenicity and differential properties of each of these individual epitopes were further characterized. To evaluate the time course of the antibody response, BALB/c mice were immunized with the HIV-1 p24 protein and their serum titers against each of these peptides were determined. The earliest immune response was observed against the p24 (202-221) peptide, which also showed the highest antibody titer against the immunized antigen. Furthermore,. enzyme-linked immunosorbent assay with HIV-1 p24 protein coated microtiter plates revealed that anti-p24 (202-221) antiserum has the most pronounced reactivity against the native p24 protein. Since the p24 (202-221) epitope has also been reported to include a cytotoxic T-lymphocyte epitope, it is suggested that this region might represent a powerful antigenic site responsible for eliciting both T- and B-cell immune response. The possible application of this specific epitope in vaccine development or AIDS diagnosis is discussed.

Tumor-draining lymph node (TDLN) lymphocytes contain immunologically sensitized to tumor but functionally deficient T cells. The 30 kDa protein antigen, a major secreted protein antigen of Mycobacterium tuberculosis, exhibits strong T cell stimulatory effect. In this study, it examined that the feasibility of using M tuberculosis 30 kDa antigen to stimulate tumor-draining lymph node cells for the generation of specific immune effector cells. Freshly isolated TDLN lymphocytes could directly respond to the 30 kDa antigen alone and their proliferative responses were markedly augmented by stimulation with rIL-2. TDLN cells were stimulated with the 30 kDa antigen for various time intervals and examined for the induction of IFN-r and IL-4 mRNA using RT-PCR. The expression of IFN-r mRNA was greatly augmented after 1 wk, whereas IL-4 mRNA is markedly decreased after 1 wk. Cytotoxic T cell activities induced by the 30 kDa antigen was also evaluated. TDLN cells stimulated with the 30 kDa antigen alone were able to generate remarkable cytotoxic response to K562 or Daudi cell lines after 6 days of culture. And their cytotoxic effects were highly augmented by stirnulation with rIL-2. These results suggest that the 30 kDa antigen of M. tuberculosis may selectively activate Thl cells of TDLN lymhocytes and induce the cytotoxic T cell activities. In conclusion, the 30 kDa antigen can be used as a biologic response modifier in tumor immunology.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii Steindachner , in the downstream of Hyungsan river which is located in Kyungpook province of Korea, were carried out, and the following results were obtained. Metacercariae of Metagonimus species were found in seventy five fishes (40.5 percent) out of 185 examined. Parasitic frequencies of the encysted matacercaria of Metagonimus species in Tribolodon taczanowskii were 23.2 percent (43 out of 185) in the scale, 7.0 percent (13 out of 185) in the gill, and 10.3 percent (19 out of 185) in the flesh. The number of the metacercaria in the scale, gill and flesh were fewer than that of the others. The worms were identified as Metagonimus yokogawai Katsurada, 1912 by morphological studies on the adults and eggs, and compared with prereported Metagonimus species.
