To gain information on retrotransposons in the genome of Paragonimus westermani, PCR was carried out with degenerate primers, specific to protease and reverse transcriptase (rt) genes of long-terminal-repeat (LTR) retrotransposons. The PCR products were cloned and sequenced, after which 12 different retrotransposon-related sequences were isolated from the trematode genome. These showed various degrees of identity to the polyprotein of divergent retrotransposon families. A phylogenetic analysis demonstrated that these sequences could be classified into three different families of LTR retrotransposons, namely, Xena, Bel, and Gypsy families. Of these, two mRNA transcripts were detected by reverse transcriptase-PCR, showing that these two elements preserved their mobile activities. The genomic distributions of these two sequences were found to be highly repetitive. These results suggest that there are diverse retrotransposons including the ancient Xena family in the genome of P. westermani, which may have been involved in the evolution of the host genome.

The evolutionary course of the CsRn1 long-terminal-repeat (LTR) retrotransposon was predicted by conducting a phylogenetic analysis with its paralog LTR sequences. Based on the clustering patterns in the phylogenetic tree, multiple CsRn1 copies could be grouped into four subsets, which were shown to have different integration times. Their differential sequence divergences and heterogeneous integration patterns strongly suggested that these subsets appeared sequentially in the genome of C. sinensis. Members of recently expanding subset showed the lowest level of divergence in their LTR and reverse transcriptase gene sequences. They were also shown to be highly polymorphic among individual genomes of the trematode. The CsRn1 element exhibited a preference for repetitive, agenic chromosomal regions in terms of selecting integration targets. Our results suggested that CsRn1 might induce a considerable degree of intergenomic variation and, thereby, have influenced the evolution of the C. sinensis genome.

Clinical characteristics and coronary angiographic findings were analyzed in 24 patients with angiographically documented coronary artery spasm, which developed spontaneously in 11 cases and was provoked by intravenous ergonovine meleate in 13 cases. The commonest clinical presentation was chest pain at rest in 21 out of 24 cases, and nine patients with resting angina had also exertional chest pain. Ten patients complained of chest pain which developed especially at night and in the early morning. Cumulative doses of ergonovine meleate whoch were required to provoked spasm were 0.05mg in 3, 0.15mg in 8 and 0.35mg in 2 cases. Transient hypertension occured in one case as a complication of ergonovine provocation test. In 20 cases coronary artery spasm developed at the portion of normal or insignificantly narrowed coronary arteries, at the severely stenotic portion in 3 cases and at the normal portion different fropm severe tight lesion in one case. Electrocardiographic findings at the time of coronary spasm were ST segment elevation in 11 among 18 cases, ST segment depression in 2 cases and no change in 3 cases. Twenty two patients complained of chest pain of the same characteristics which they had previously experienced, but there was no chest pain in 2 patients. Right coronary artery was the most prevalent site of coronary artery spasm, and percutaneous transluminal coronary angioplasties were performes successfully in 4 cases with significantly tight lesions. In conclusion coronary artery spasm is thought to play a significant role in the conversion of stable to unstable angina and the development of silent myocardial ischemia as well as variant angina.

The 150 kDa protein of cyst fluid (CF) of Taenia solium metacestodes was purified by ammonium sulfate fractionation and Superose 6 HR gel filtration chromatography. The purified protein consisted of three subunits (15, 10 and 7 kDa proteins), which were analyzed with the use of a 7.5-15% gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Immunofluorescence study was carried out by using immunize specific polyclonal antibody. Positive reactions were noticed at bladder walls, calcareous corpuscles, granules of cyst fluid and some host tissue surrounding the bladder wall of the metacestodes. These results suggest that the 150 kDa protein was secreted into host tissues, inducing immune responses in the host, and it may play important roles in the cellular physiology of the parasites.

Separation of Langerhans cells in epidermis of 16 healthy Korean individuals were performcd. Separation of Langerhans cells by density gradient centrifugation on a colloidal sillica(percoll) polyvinilpyrrolidone gradient. And autologous, allogeneic mixed skin cell leukocyte culture reaction was done with each fractionatcd cpidermal cell suspensions. Also lymphocytes, epidermal cells was cultured in media alone, respectively. The results was quantitated by the incorporation of H-thymidine by p-liquid scintillation counter. The densities of I angerhans cells within the epidermal cells, fraction-2 was most higher concentration (22.0+2.8%) and fraction-5 was most lower concentration (3.4+ l.9%). 2. In the comparison of the results of Langehans cells enriched and depleted population in autologous mixed skin cell leukocyte culture reaction, the former was higher than the latter on lymphocyte stimulatory capacity. There was significant differences(p<0.005) And also same as result in allogeneic mixed skin cell leukocyte culture reaction. 3. Langerhans cells enriched fraction in this study was more lymphocyte stimulatory capacity than depleted fraction in allogeneic mixed skin cell leukocyte culture(p<0.01~0.05). Ailogeneic mixed skin cell leukocyte culture reaction was more lymphocyte stimulatory capacity than the autologous(p<0.005~0.05).
