  • Mucoepidermoid carcinoma is most frequent malignant tumor of parotid gland. However, mucoepidermoid carcinoma arising from pleomorphic adenoma has been disputed and rarely reported. 54-year-old woman with pleomorphic adenoma underwent superficial parotidectomy. And 15 years later, she diagnosed mucoepidermoid carcinoma at the same side. We report the case with a review of literature.

  • G- and C-banding pattern analyses of striped field mice (Apodemus agrarius coreae) using 17 specimens from four localities in Korea revealed that centromeric heterochromatin results in the variation of No. 1 chromosome pair (telocentri $c_telocentric), i.e., centromeric heterochromatin sometimes appeared to be recognized as short arm. G- and C-banding patterns of four black rats (R. rattus rufescens) from two localities in Korea showed that No. 1 chromosome polymorphism (telocentri $c_telocentric) is due to pericentric inversion. In addition, G- and C-banding patterns of black rats mentioned above are idiogrammed.ammed.

  • The phenotyping of the sixth complement component (C6) was performed on plasma or serum samples from 383 unrelated Korean, by IEF and immunoblotting using anti-human C6 serum. Three common allotypes, C6 A, C6 B and C6 B2 and two rare allotypes, C6 Ml and C6 Mu were observed. The allele frequencies of C6*A, C6*B and C6*B2 were estimated to be 0.4399, 0.5144, 0.0392, respectively. These frequencies are similar to those of the Eastasian populations.

  • One of the mitochondrial genes, called cytochrome c oxidase I (COI), has been widely used for the species identification (called bio-barcode) in birds. In this study, the bio-barcode has been applied to chicken breeds in Korea whether it also can be used as a molecular marker for breed identification. Data indicated that Korean native chicken has the mixed SNP (single nucleotide polymorphism) patterns between White Leghorn (Layer) and Cornish (Broiler) and ultimately, it can not be used as the marker for breed identification. However, this result indicates the mixed use of the Korean native chicken, since it has been used for dual purpose for producing meat and egg for a long time. In order to use as a marker for species identification, more reliable mitochondrial and/or nuclear DNA markers need to be developed.

Estimating Diameter and Height Growth for Pinus densiflora S. et Z. Using Non-linear Algebraic Difference Equations (비선형(非線型) 대수차분(代數差分) 방정식(方程式)을 이용(利用)한 소나무 직경(直徑) 및 수고(樹高) 생장(生長) 추정(推定))

  • Pinus densiflora S. et Z. has widely been distributed, and is one of the important main foret resources in Korea. Diameter and height growth patterns were estimated using non-linear algebraic difference equation, which requires two-measurement times $T_1$ and $T_2$. To maximize data use, all possible measurement interval data were derived using Lag and Put statements in the SAS. In results, of the algebraic difference equations applied, the Schumacher and the Gompertz polymorphic equations for diameter and height, respectively showed the higher precision of the fitting. In order to allow more precise estimation of growth than those of the basic Schumacher and the Gompertz, further refinement that combine biological realism as input into the equation would be necessary.

  • We examined mRNAs, isolated from the rat brain, to ascertain if there is any polymorphism for S-100 beta protein gene. As templates for polymerase chain reaction (PCR) the reverse-transcribed cDNA from the rat brain or phage DNAs isolated from the rat brain cDNA libraries were used. Although PCR products turned out to be exactly same as the expected size based on the previously reported mRNA sequence a single base substitution (CAT to CAC) was identified at nucleotide level. This change was considered as polymorphism since it did not cause any change of the primary structure for S-100 beta protein. This result should facilitate the understanding of the overall structure of the gene for S-100 beta protein.

  • Genetic variation of the beet armyworm, Spodoptera exigua (Hubner), was analyzed by polymorphic allozymes. Field populations were subdivided by different hosts, geographical locations, and seasons. Estimated average heterozygosity ($0.443\pm$0.013) indicated high genetic variation in all field populations of S. exigua. There were significant inbreeding effects deviated from Hardy-Weinberg equilibrium in each of subpopulations. These significant nonrandom matings were caused by within-subpopulations probably due to sampling errors, but not by mating isolation among subpopulations. Wrights ($F_{ST}$ ) and Neis (D) genetic distances indicated little genetic differentiation among subpopulations, though some southern local subpopulations (Haenam and Sachon) were relatively different of northern subpopulations (Andong and Kunwi). Estimated number of migrants per generation was 5.9 among host subpopulations, 10.6 among geographical subpopulations, and 31.8 among seasonal subpopulations. These genetic analyses suggest that Korean S. exigua subpopulations have little genetic differentiation mostly due to their significant migratory capacity.
