Genic variation and genetic similarities among eleven species of the subfamily Acheilognathinae (Cyprinidae) were analysed, by means of starch gel electrophoresis, in order to estimate their phylogenetic relationships and to estimate the degree of genic variation in each species. A sum of 222 individuals from 10 geographic areas representing 24 population was used in this experiment. Among 222 specimens, 5 specimens of each species were used for species comparison and rest were used for the estimation of degree of genic variation in each population. The results are as follows : 1. Rogers' genetic similarity coefficients (S) between Rhodeus suigensis and R. atermius was S=0.961. Therefore it is assumed that these two species are conspecific and probably R. atremius was misidentified, i.e. R. atremius is R. suigensis, as suggested by Kim(1982). 2. Acheilognathus signifer and A. limbata were treated as synonym by kim(1982) based on morphological similaritics but the present data show that they might be two good species since S value between these two is S=0.687 and this value is low enough to treat as two independent species (Avise and Smith, 1977). 3. Dendrogram of eleven species of the Acheilognathinae fish shows three species groups based on the genetic level. Therfore we suggest the following tentative classification. Genus Acanthorhodeus qracilis Genus Acheilognathus intermedia limbata signifer Genus Rhodeus suigensis uyekii ocellatus rhombea yamatsutae asmussi However, further intensive survey would be required to verify this classification since we had no adequate sample size to convince this result. 4. Dgree of genic variation of the subfamily Acheilognathinae, expressed by % polymorphism and heterozygosity, was very low compare to other fish groups (Selander, 1976). Probable causes of this are not known but partially it may be due to the small sample size invetigated.

Allozymic variation in proteins encoded by 20 loci was analysed electrophoretically in 265 specimens of six species of the Subfamily Acheilognathinae, representing 16 populations from 9 geographic area in Korea. The results are as follows : 1. Of the 20 loci examined, 4 loci (Ldh-1, Idh, Ab-1, Pept-2)were monomorphic and fixed with identical mobility. Adh was monomorphic in all populations with alternative alleles in each species. Out of the remaining 15 loci, 7(Ldh-2, Ab-2, Sdh, Ipo, Aco, Est-1, Pgi-1) were very weakly polymorphic, 4 (Mdh-2, Pgm, Pgi-2, Pept-1) were locally and moderately polymorphic, and 4 (Mpi, Gpd, Pept-3, Mdh-1) were strongly polymorphic. 2. In the estimate of genic variation, mean proportion of loci polymorphic per populations, and loci heterozygous per individual, the Acheilognathinae species display much lower than average estimates of genetic variation (Ayala, 1982), as mentioned in the previous paper (Yang and Park, 1982). 3. Genetic similarity within populations of each species was very low compare other fish groups (Avise, 1976). Probable caused of this are not known but few possible reasons were speculated.

보신 관광에서 감염된 수입성 Sparganosis 1예 : Intake of Thailand Snake during Trip

서환조,박명재,고경식,백영한,조유정,양현종,류경남,정형근,전정열 대한감염학회 1992 감염 Vol.24 No.1

Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).

Fourty-seven cases of mediastinal tumors originating in the mediastinum or metastasized from other organs were reviewed and classified on the basis of histopathological types and specific anatomical location in this department, during 13 years and six months period from Jan. 1959 to Jun. 1971. In thirty-seven cases, diagnosis was confirmed by histological findings. Range of age was 3 to 63 years and sex ratio was 1.4:1 male to female. In this series, metastatic mediastinal carcinomas of unknown pimary site were most frequent and thymoma ranked second in frequency, comprising 24.3% and 16. 2% of the total cases. The operative mortality was 3.1 There were histologically 11 different kinds of mediastinal tumors in this series.

First Record of a Brown Frog Rana huanrenensis (Family Ranidae) from Korea

Yang, Suh-Yung,Kim, Jong-Bum,Min, Mi-Sook,Suh, Jae-Hwa,Kang, Young-Jin,Matsui, Masafumi,Fei, Liang The Korean Society for Integrative Biology 2000 Korean journal of biological sciences Vol.4 No.1

We found a brown frog species, which is unrecorded from South Korea. Rana huanrenensis Fei, Ye, and Huang (1990), This species was originally described from northeastern China. In having 2n=24 chromosomes, this species is closely related to Rana dybowskii, R. chensinensis, R. ornativentris, R. pirica, and Chinese R. huanrenensis, but it is different from the first four species in the ecological, morphological, and genetic characteristics. By contrast, this species Is identical to Chinese R. huanrenensis In the habitat of montane stream-breeding, absence of the vocal sac, and genetic properties. This record is a significant range extention of R. huanrenensis.

Genetic and Phenetic Differentiation among Three Forms of Korean Salamander Hynobius Ieechii

Yang, Suh-Yung,Kim, Jong-Bum,Min, Mi-Sook,Suh, Jae-Hwa,Suk, Ho-Yung The Korean Society for Integrative Biology 1997 Korean journal of biological sciences Vol.1 No.2

Genetic and morphological variations of Korean Hynobius leechii were surveyed. Starch gel electrophoresis was used to study genetic variation at 23 loci. H. leechii is genetically divided into three groups, each of which is named as Form-A, Form-B, and Form-C. These forms are clearly separated with 4-5 fixed or nearly fixed allelic differences. At a sympatry near Jangseong, Jollanam-do, a significant deviation from random mating between Form-A and Form-B was observed. Therefore, they are considered as two distinct taxi of specific rank. Form-A is widely distributed in the inland of Korea, whereas Form-B is distributed in the islands or near the coastal regions of Western and Southern Korea. Form-B had, in addition, a significant morphological difference from Form-A. On the other hand, Form-C was restricted to an area near Kori atomic power plant, Kyongsangnam-do, and the genetic similarities between this form and Form-A and Form-B were 0.742 and 0.736, respectively. Moreover, Form-C had a unique color pattern, short body and small coccyx. Thus, it seems reasonable to assign this form as another new species.

Genetic Diversity and Speciation of Rana rugosa (Amphibia; Ranidae)

Yang, Suh-Yung,Min, Mi-Sook,Kim, Jong-Bum,Suh, Jae-Hwa,Kang, Young-Jin The Korean Society for Integrative Biology 2000 Korean journal of biological sciences Vol.4 No.1

Horizontal starch gel electrophoresis for 29 populations (n=543) of the wrinkled frog, Rana rugosa, from Korea and Japan was peformed to assess the degree of genic variation and genetic diversity, and to understand the biogeographic pattern of distribution and speciation. A sum of 22 presumptive loci was screened from 17 enzymes and general proteins. Four loci, Aco, Est-3, Me-2, and Pgm, demonstrated high levels of polymorphism. The degree of average genetic variation of R. rugosa was P=22.7% (9.1-40.9%), Ho=0.086 (0.048-0.165) and He=0.090 (0.042-0.168). In the south-eastern region of the Korean peninsula (Chongsong, Yongchon, Ulsan, Kyongju, Pohang, yongdok and Ulchin), a few unique alleles in the Mpi locus were detected and their biogeographic implications were considered. The degree of genetic differentiation among the Korean populations was moderate (S=0.900), whereas the degree of genetic diversity between Korean and Japanese populations was notably high (S=0.687, D=0.293). This result corresponds with the data obtained by the mitochondrial cytochrome b gene sequence (Lee et al., 1999) suggesting that the Korean and Japanese R. rugosa might have evolved a specific level of genetic differentiation since their geographic isolation.

Genetic Diversity and Population Structure of Kaloula borealis (Anura, Microhylidae) in Korea

Yang, Suh-Yung,Kim, Jong-Bum,Min, Mi-Sook,Suh, Jae-Hwa,Kang, Young-Jin The Korean Society for Integrative Biology 2000 Korean journal of biological sciences Vol.4 No.1

To assess the genetic diversity and population structure of Korean K. borealis, allozyme analysis was performed. The average genetic variability of Korean K. borealis populations was %P=13.2, Ho=0.048, and He=0.045. This value was the lowest in comparison with other Korean amphibian species studied. Also, the value was much lower than that of a reference population from Chinese K. borealis (%P=50, Ho=0.125, He=0.172). Wright's F-statistics showed that Korean K. borealis has distinctly low level of gene flow among regional populations (F$_{ST}$=0.339, Nm=0.487) in comparison with other Korean amphibian species studied. However, the average level of genetic divergence among Korean K. borealis populations was moderate (Nei's D=0.020). Therefore, it appeared that low levels of genetic diversity (He=0.045) and gene flow (Nm=0.487) among regional populations ave probably due to the results of decreasing population size and patchy distribution of this species in Korea.
