A study on the Aedes togoi to find out important biological and ecological factors as an efficient vector of filariasis, was carried out on Che-Ju Island for two years from 1968 though 1969. Results obtained are as followings: Geographical distribution of the mosquito breeding habitat was found to be extensive covering circular areas of about three km distance along the shore line. The main breeding sites were rockpools and smaller holes on rocks retaining tide and/or rain water with high larval density; water tanks, pots, and other artificial containers retaining only rain water around the houses located within the area with relatively low larval density. Species constitution of adult mosquitos collected in the study villages consisted largely of Aedes togoi with a range of 70-90 per cent by village. The pH of the breeding sites ranged from 5.0 to l0.0, and the chloride content from 0.01 to 28.75 (gm/l). More than fifty per cent of examined sites, however, had pH 5.6-6.5 and chloride content of less than 1.0 gm/1. The natural infection rate of A. togoi by filaria showed proportional relationships with microfilaria rates among the human population by area. Experimental infection of A. togoi by human and dog filaria demonstrated that this species is an efficient vector for both filaria species proved by natural infection as well as experimental infection. Susceptibility of both larva and adult of A. togoi to insecticide, DDT and dieldrin, showed considerable sensitivity in all villages tested.

The pharmacotherapy of schizophrenia exhibit wide inter-individual variabilities in clinical efficacy and adverse effects. Recently. human genetic diversity has been known as one of the essential factors to the variation in human drug response. This suggests that drug therapy should be tailored to the genetic characteristics of the individual. Pharmacogenetics is the field of investigation that attempts to elucidate genetic basis of an individual's responses to pharmacotherapy, considering drug effects divided into two categories as pharmacokinetics and pharmacodynamics. The emerging field of pharmacogenomics. which focuses on genetic determinants of drug response at the level of the entire human genome, is important for development and prescription of safer and more effective individually tailored drugs and will aid in understanding how genetics influence drug response. In schizophrenia, pharmacogenetic studies have shown the role of genetic variants of the cytochrome P450 enzymes such as CYP2D6, CYP2C19, and CYP2A1 in the metabolism of antipsychotic drugs. At the level of drug targets, variants of the dopamine D_(2), D_(3) and D_(4), and 5-HT_(2A) and 5-HT(2C) receptors have been examined. The pharmacogenetic studies in schizophrenia presently shows controversial findings which may be related to the multiple involvement of genes with relatively small effects and to the lack of standardized phenotypes. For further development in the pharmacogenomics of schizophrenia, there would be required the extensive outcome measures and definitious, and the powerful new tools of genomics, proteomics and so on.

We reviewed the records of 101 eyes who underwent extracapsular cataract extraction without intraocular lens implantation at Kosin Medical Center from Feb. 1987 to Mar. 1990. Of these, 47 eyes that showed postoperative corrected visual acuity of 0.5 more and more than 2 months' follow-up periods, were recruited for this study. To detect the changes of preoperative predicted aphakic refractions and postoperative observed aphakic refractions. we studied the changes of pre- and postoperative axial lengths, keratometric measurements, and observed aphakic refractions at postoperative 2 months were compared with predicted aphakic refractions, using linear regression formula. The results were as follows: 1. Distribution of age were in the range of 24 to 79 years(mean, 59.4 years), and seventh decade(31.8%) was most common. 2. Postoperative keratometric measurements was decreased in power of mean +/- SD; 0.04 +/- 0.14 diopters(p>0.05). 3. Postoperative axial length was increased by 0.20 +/- 0.09mm(p<0.05). 4. The difference between pre- and postoperative refractive power was mean +/- SD; 0.58 +/- 0.16 diopters(p<0.05).

Polymerase chain reaction (PCR) amplication was used to detect cytomegalovirus (CMV) in tissue culture from the urine of newborns and patients who was suspected CMV infection, Synthetic oligonucleotide primer pairs were used to amplify DNA from the major immediate-early and the phosphoprotein 150 genes of CMV AD 169. Amplified products were detected by gel electrophoresis and by dot-blot hybridization with oligonucleotide probes. We found 12 different tissus culture isolates of CMV after the microimmunoassay using monoclonal antibody to immediate-early antigen. All 12 isolates were positive after PCR amplification. But there was no positive reaction when the same primers and probes were used to amplify herpes simplex virus and human genomic DNA. Twelve urine samples were positive when tested with one or both primer pairs and probes. When compaired tissue culture, detection gel electrophoresis provide a sensitivity of 91% (11/12), dot-blot analysis raised the sensitivity to 100% (12/12). A specificity of both primer was 100%(0/12). We conclude that PCR amplification may be a valuable tool for diagnosing congenital CMV infection.

Melorheostosis which is a rare form of hyperostosis characterized by its linear pattern of distribution along the major axis of long bone was initially described by Leri and Joanny in 1922. A case of melorheostosis mostly involving the right upper extemity as a monomelic type was presented here because of its rarity of the disease.

Indirect fluorescent antibody tests were performed with sera of paragonimiasis patients and skin test positive sera against Paragonimus antigen. Paragonimus antigen was prepared from lyophilized adult worms of P. westermani by defatting with ethyl-ether before extracting with barbital buffered saline. Preparation of Paragonimus antigen for the indirect fluorescent antibody test was based upon Sato's method used for sero-diagnosis of anisakiasis, with Sephadex G-25 instead of Sepharose 4B. The results were as follows: The indirect fluorescent antibody titers of paragonimiasis patient's sera ranged from 1:64 to 1:512, whereas the control sera showed titers of less than 1:16. As controls, Clonorchis patient's sera and parasite-free healthy human sera were used. In indirect fluorescent antibody tests, the skin test positive human sera against Paragonimus antigen showed a positive rate of 41.5 per cent in the case of titers more than 1:40. On the other hand, complement fixation tests on the same sera showed a positive rate of 32.5 per cent in the case of titers more than 1:20.
