제주마의 세 구룹의 집단(group I , 제주도축산진홍원 관리마; group Il , 농가사육마; group III, 제주경마장의 경주마)과 외래품종인 Thoroughbred, Mongolian horse 및 Quarter horse에 있어서 transfemin 유전자 분포를 비교하기 위하여 Transferrin 유전자 exon 13, 15 및 16에 대하여 SSCP 분석을 수행하였다. 조사된 유전자의 빈도는 집단간의 유전적 분화거리를 측정하는데 이용되었고 집단분화의 유의성을 검정하였다. 집단분화를 나타내는 Fst 값에 의하면 제주마 group I 은 group Il (0.067) 및 group III(0.070)와는 가깝게 위치하고 있었으나 Mongol 집단과는 0.091 로， Thoroughbred 집단과는 0.189의 유전적으로 거리가 다소 먼 분화된 집단관계를 보여주고 있었다. 또한 제주마 group I 은 외래품종인 Thoroughbred, Mongolian horse, American Quarter 집단뿐만 아니라 제주마 group Il 및 m와도 차별화 되는 집단으로 유지되고 있음을 보여주고 있었다'(p <0.05). 제주 경마장에 경주마로 이용되고 있는 제주마 group ill는 제주마 group I 및 Thoroughbred 품종집단에 대해서 칩단분화에 유의성이 안정 ( p < 0.01)되 었고 나머지 다른 집단과는 집단분화의 유의성이 없었다(p > 0.05). 제주마 group Il, group Ill 및 몽고마 사이에는 분화 확률의 유의성이 없어서 이들 집단간에는 유전자 빈도가 매우 유사한 것으로 생각되었다. 이로서 비교적 짧은 기간에 번식환경의 격려 또는 외래품종의 유전자 유업에 의하여 제주마의 transferrin 유전자 빈도는 제주마 집단간에 이질화를 초래하고 있으며， 집단의 분화가 유전자의 유엽이 원인이라면 혈통보존되는 축산 진홍원의 관리집단 이외의 제주마 집단은 외래 품종의 유전자 유업으로 제주마의 고유한 유전적 특성이 빠른 속도로 희석될 것으로 생각된다.

The purpose of this study is understanding the principle of space construction in traditional houses in Cheju under the premise of house being the dweller's place. I studied it by shamanist interpretatiov. First I understood the quality and meaning of space by the theory of space and shamanism. As the method of study. I studied the space theory and shamanism and had a general idea of them. And then I looked upon the concept of space as residence and analyzed the traditional houses in Cheju. The conclusion of the study is this. I considered shamanism as a part of their way of life. Thus shamanism was a chief idea of Cheju people's thought, religion, and a view of the world. Naturally shamanism was the chief principle with which Cheju people constructed the residence. Because this cultural social aspect of shamanism, it is understood and used as the principle of space construct in modern architecture of Cheju.

The anti-inflammatory activity of Eurya emarginata (Thumb) Makino, of which leaves have been traditionally used to treat ulcers or diuretic in Jeju Island, has been investigated in the present study. Through the phytochemical study from the methanol extract of E. emaginiata, eutigosides Band C were isolated as the active components. Sseveral inflammatory markers including TNF-$\alpha$, IL-1$\beta$, IL-6, NO, iNOS, and COX-2 were examined. Eutigosides Band C potentially inhibited production of pro-inflammatory cytokines (IL-6 and TNF-$\alpha$) in a dose-dependent manner. Additionally, the intracellular contents of iNOS protein were markedly decreased after treatment with eutigosides Band C. The inhibition of iNOS activity was correlated with the decrease in nitrite levels. These results suggest that eutigoside Band C from E. emarginata may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines (TNF-$\alpha$ and IL-6), iNOS and COX-2.

The present study was carried out to investigate the blood markers of Cheju horses. The red cell types (blood groups) were tested from 73 Cheju native horses and 118 Cheju racehorses by serological procedures with 23 reagents. The blood group phenotypes observed with high frequency were Pb(34.3%), Qc(56.2%), Qb(15.1%) and genotypes Dbcm/dghm(12.3%), Dde/dghm(9.6%), Dad/bcm(6.8%), Dcgm/de(6.8%) in Cheju native horses, while Aa(63.6%), Pa(44.9%), P-(28.8%), Qabc(36.4%), Dbcm/cgm(14.4%), Dbcm/bcm(10.2%), Dbcm/de(7.6%), Dbcm/dghm(5.1%), Dde/dk(5.1%) in Cheju racehorses. Alleles observed with high frequency were Ab(0.128), Ac(0.169), Dad(0.103), Dadn(0.075), Ddghm(0.226), Pb(0.316), Qc(0.494) in Cheju native horses and Aa(0.529), Dbcm(0.306), P-(0.531), Qabc(0.197), Q-(0.504) in Cheju racehorses. No specific variation of blood groups and allele frequencies of C,K,U system were observed in Cheju native horses and Cheju racehorses. The mean heterozygosity in Cheju native horses and Cheju racehorses was observed 0.5344 and 0.5102, respectively.

Bamboo grass, Sasa quelpaertensis, is a native plant to Jeju Island, Korea. The leaves of Sasa plants are widely used in traditional Korean medicine to treat inflammation-related diseases. We investigated the effect of hot water extract from Sasa quelpaertensis leaves (HWE-SQ) on nitric oxide (NO) production and nuclear $factor-{\kappa}B\;(NF-{\kappa}B)$ activation in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. HWE-SQ inhibited LPS-induced NO production and inducible NO synthase (iNOS) protein expression in a dose-dependent manner. Reporter gene assays indicated that HWE-SQ decreases LPS-induced $NF-{\kappa}B$ transcriptional activation. However, HWE-SQ did not affect the phosphorylation and degradation of inhibitory ${\kappa}B{\alpha}\;(1{\kappa}B{\alpha})$. HWE-SQ also directly inhibited iNOS enzyme activity in a dose-dependent manner. These results suggest that HWE-SQ suppresses NO synthesis in macrophages by attenuating $NF-{\kappa}B-mediated$ iNOS protein expression and inhibiting iNOS enzymatic activity, thereby implicating a mechanism by which HWE-SQ is able to ameliorate inflammation-related diseases by limiting excessive or prolonged NO production in pathological events.

In Korea, the collapse of traditional Patriarchal family system has caused the weakening the patriarchal authority which represents the decrease of traditional attitude of respect for old age, influenced by the strong tendency of Materialism in ethics. The urgent problem is how to solve the conflicts of the alienation almost every old people has felt from the society and family which they belong to and how to harmonize the respect for old age who used to have had in the past. From 21st to 30th of July 1979, I explored the small village in Cheju Island with eight students which I selected on purpose that village had preserved the traditionalism. I collected the interview data form a sample of 221 persons of the village in Cheju Island. I studied this small village in Cheju Island for the intention of suggesting the ideal model of regional society which both traditional and non-formal, although the phenomena of nuclear family system and materialism and industrialism are overwhelming in ur present society. Generally people in Cheju Island are economically poor and major occupation is farming, since the industrialization proceeds very slowly and there still strongly remains the traditionalism. Alienation and dissatisfaction of old people from their family and society in Cheju island are less common in comparison to the main land. Old people in Cheju Island usually value the importance of labour. Divison of labour has been well observed in farming, and men and women in Cheju island are equally regarded in comparison to the main land. Old people are independent economically and spiritually from their offsprings and they organize the nuclear family system firmly. Also the old generation is ready to compromise with the new generation and they defy the authoritariansim.

Scavenging effects of DPPH radical and hydroxyl radical, inhibition of linoleic acid oxidation, inhibition of NO synthesis and iNOS expression were tested with extracts and chromatographic subfractions of Canavalia lineata obtained at Jeju island. Chloroform extract and its subfractions gave moderate effects on scavenging DPPH radical and hydroxyl radical, They also inhibited linoleic acid oxidation, and NO synthesis. Inhibition of NO synthesis resulted from the repression of iNOS gene expression. Ethyl acetate extract and its subfractions showed excellent effects on scavenging DPPH radical and hydroxyl radical, while they were cytotoxic.

We evaluated the effects of extracts of Tsunokaori tangor peel on lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ in RAW 264.7 cells. The ethyl acetate fraction of Tsunokaori tangor peel (EA-TTP) markedly inhibited the production of NO and $PGE_2$ in LPS-stimulated RAW 264.7 cells. Consistent with these findings, the expression levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) proteins were down-regulated in a dose-dependent manner. Additionally, EA-TTP decreased the expression iNOS mRNA but not COX-2 mRNA. To determine the upstream signaling mechanism for the down-regulation of LPS-induced iNOS expression, we investigated the effect of EA-TTP on the degradation and re-synthesis of $I{\kappa}B{\alpha}$. EA-TTP dose-dependently delayed $I{\kappa}B{\alpha}$ degradation and increased $I{\kappa}B{\alpha}$ re-appearance following degradation, suggesting this as the mechanism by which EA-TTP suppressed iNOS gene expression. The EA-TTP also dose-dependently reduced the expression of the cellular stress-response protein heme oxygenase-1, and inhibited the LPS-induced sustained activation of extracellar signal-regulated kinase (ERK).

Nitric oxide synthase (NOS) has been reported in uterus. We examined the expression of the NOS isoforms, constitutive endothelial (eNOS) and inducible NOS (iNOS), in bovine uterus by immunohistochemistry. eNOS immunoreactivity was localized predominantly to the endothelial cells that line uterine microvessels and to endometrial glandular epithelial cells, but was barely detectable in endometrial stromal cells. iNOS immunostaining was detected in glandular epithelial and stromal cells in the endometrium and in the endothelial cells of myometrial blood vessels. These findings suggest that both eNOS and iNOS may play important roles in the physiology of the uterus, possibly by generating NO.

As a result of the detection of mitochondrial DNA(mtDNA) polymorphism to Thoroughbred and Percheron using 14 restriction enzymes, mtDNA polymorphism of Cheju horse observed in the Bam HI and Sac I. Only in both restriction enzymes two types were classified as of A type, which is high expression frequency and B type, which is low expression frequency. In the other 12 restriction enzymes mtDNA polymorphism was not detected. On the basis of this information mtDNA polymorphism of Cheju horse was examined but was not observed the polymorphism and only A type was expressed both Bam HI and Sac I restriction enzymes. Through this study Cheju horse was demonstrated that lower genetic variation was expressed from the detection of mtDNA polymorphism.
