The Karyotypes of Korean Sciurus uulgaris coreae and Tamias sibiricus asiaticus were analyzed by the G-banding method. Chromosomes of two species could be identified by G-banding patterns. The banding patterns of chromosomes 9, 10, 12 and X of S. vulgaris coreae were identical to those of chromosomes 6, 9, 12 and X, respectively of T. sibiricus asiaticus. It was shown that chromosomes 4, 10, 7 and 17 of T. sibiricus asiaticus resulted from pericentric inversion of chromosomes 1, 7, 8 and 16 of S. vulgaris coreae. These results suggested that pericentric inversion was an important factor in the karyological differentiation of two species.

The comparative karyological analysis of the Korean treefrog, Hyla japonica and Hyla suweonensis performed by conventional giemsa-staining and NOR-staining method. The karyotypes of both species were the same (2n=24). However, according to the Karyological analysis, the 6th chromosomes of the two species distinctly different. Eventhough the 6th chromosomes of the two species shown the same % length, construction of the 6th chromosome of H.japonica was subtelocentric chromosome while H. suweonensis was submetacentric chromosome. This phenomena could explain that the morphological differences in the 6th chromosomes might be caused by pericentric inversion. The two species have 1 pair of NOR site in the 6th chromosome.

The chromosomal analyses of Dendmcopos major hondoensis and D. leucotos Ieucotos(Picidae:Piciformes) in Korea were performed by conventional Giemsa staining and C-banding method. The diploid number of two species was 2n=90-92 and arm number was AN= 92-96.The conventional karyotypes were very similiar but distribution of constitutive heterochromatin were differ in the first chromosome. The second and several pairs of macro-telocentric chromosbmes have telomeric constitutive heterochromatin.

The chromosome morphology of two Korean Lactuca (L. indica, L. triangulata) is reported herein. The chromosome number and karyotype of a naturalized plant, L. scariola are reported for the first time. The basic chromosome number was x = 9. Polyploid forms were not recorded. The karyotypes of L. indica, L. scariola, and L. triangulata were 2 n = 18 = 2 m+ 7 sm, 2 n = 18 = 1 m + 6 sm+ 2 st, 2 n = 18 = 2 m + 5 sm+ 2 st, respectively. Both L. indica and L. triangulata had satellites at the ends of their short arms. The haploid genome lengths of L. indica, L.scariola, and L. triangulata were $56.3{\mu}m$, $35.3{\mu}m$, and $72.5{\mu}m$ respectively. Each chromosome length of naturalized L. scariola was $2.7-5.2{\mu}m$; the smallest among Korean Lactuca. The chromosome lengths of L. indica and L. triangulata were $4.7-7.6{\mu}m$ and $2.9-7.9{\mu}m$, respectively. The karyotype of L. scariola differed from that of L.indica and L.triangulata both of which belong to sect. Tuberosae. Therefore, L. scariola is thought to belong to sect. Lactuca subsect. Lactuca.

Purpose : The prevalence of renal malformation in Turner syndrome has been quoted as being greater than 50% in older series. Recently in 1988, Lippe's review gave a prevalence of 33%, significantly lower than all previous reports. In 1996, Flynn reported that renal malformation occurs in approximately 24% of all girls with Turner syndrome, and that it is seldom seen in girls with mosaic karyotype who form the predominant subgroup. The aim of this study was to evaluate prevalence of renal malformation by karyotype in Turner syndrome in Korea. Method : We evaluated 81 patients with Turner sundrome diagnosed in Yonsei University from Jan. 1987 to Dec. 1996. The patient entered in this study were those for whom both karyotype and ultrasound examination of the kidney were available. Result : 1) The karyotype showed: 45,X ; 29 cases (38%), mosaicism : 32 cases (40%), structural aberration ; 17 cases (22%). 2) Of the 29 cases of pure 45,X karyotype, 5(17%) had abnormal renal findings, while these were found in only 1 of the 30 mosaic cases(3.3%), and in 1 of the 17 structural aberration cases(6%). The malformation included 3 cases of horseshoe kidney, 2 cases of axial malrotation, hypoplastic kidney and simple cyst each one. There was no statistical significance between 3 groups (p=0.09). Conclusion : We conclude that renal malformation occurs in 9.2% in this study, therefore Korean girls with Turner syndrome have lower rates of renal malformation.

연두순부(Ischnochiton comptus)와 가는 줄연두군부(I. hakodadensis)두 종의 정소를 재료로하여 핵형 분석을 실시하였다. 두 종의 염색체는 모두 중부염색체로 구성되어 있고, 염색체 수는 n=12이며, 성염색체는 관찰되지 않았다. 이들 염색체는 이들의 크기로는 별도의 염색체군으로 나누어지지 않았다.

1996년 8월 춘천 의암호에서 채집한 긴애기물달팽이(Fossaria truncatula)를 재료로 공기건조법을 이용하여 통상적인 방법으로 염색체를 관찰하고 핵형을 분석하였다. 그 결과 긴애기물달팽이의 염색체 수는 2n=31, 32이었으며 15쌍의 배수체와 1개의 성염색체를 가지고 있었다. 핵형은 3쌍의 metacentric과 13쌍의 submetacentric 염색체로 구성되어 있었다.

The karyotypes of three species of Gobiobotia in Korea were investigated: G. macrocephala, G. brevibarba, and G. nakdongensis. In these species, the mitotic chromosomes from 25 groups with two chromosomes each indicated that it is a diploid. The karyotypes of Gobiobotia macrocephala are 2n = 50 (9M+7SM+9ST) with NF = 100, G. brevibarba 2n = 50 (10M+7SM+4ST+4T) with NF = 92, and G. nakdongensis 2n = 50 (5M+9SM+9ST+2T) with NF = 96. Chromosome sizes ranged from 3.3 to $7.5{\mu}m$, 2.7 to $6.3{\mu}m$ and 3.5 to $7.3{\mu}m$ in length, respectively. This is the first report on the chromosomes of G. macrocephala and G. nakdongensis.
