  • This study was carried out for the objectification and clinical application of the Sasang Constitutional Medicine(四象醫學). So, the Taeum Soyang, Soum groups were classified by diagnostic rules of Sasang constitution, and investigated by Amp-FLP method far genetic difference. The Amp-FLP was one of the most frequently used human genetic analysis methods which adopts STR typing. In this study, 100 genomic DNA samples of Taeum, Soyang, Soum constitution group were analysed by Amp-FLP method. Allele frequencies of four tetrameric short tandem repeat(STR) loci(TPOX, LPL, D21744, and D13S317) were determined in Taeum, Soyang, Soum groups. The heterozygosities and the polymorphism information content(PIC) values of forur STR loci were 0.812 and 0.789 in D3S1744, 0.811 in D13S317, 0.466 and 0.417 in LPL, and 0.625 and 0.561 in TPOX, respectively. The allele distribution of four STR loci was statistically evaluated. It was found out that the allele distribution of four STR loci was not significantly different among different constitutions. But all loci were found to be highly polymorphic in Taeum, Soyang, Soum groups. It was found out in this study that Taeum, Soum groups are genetically more related each other than they are related to Soyang groups.

  • Human plasma Hp is classified as 1-1, 2-1, and 2-2. They are inherited from two alleles Hp 1 and Hp 2, but there is only Hp 1 in almost all the animal species. Hp 2-2 molecule is extremely large and heterogeneous associated with the development of inflammatory-related diseases. In this study, we expressed entire bovine Hp in E. coli as a $\alpha\beta$ linear form. Interestingly, the antibodies prepared against this form could recognize the subunit of native Hp. In stead of a complicated column method, the antibody was able to isolate bovine Hp via immunoaffinity and gelfiltration columns. The isolated Hp is polymeric containing two major molecular forms (660 and 730 kDa). Their size and hemoglobin binding complex are significantly larger than that of human Hp 2-2. The amino-acid sequence deducted from the nucleotide sequence is similar to human Hp 2 containing a tandem repeat over the $\alpha$ chain. Thus, the Hp 2 allele is not unique in human. We also found that there is one additional -SH group (Cys-97) in bovine $\alpha$ chain with a total of 8 -SH groups, which may be responsible for the overall polymeric structure that is markedly different from human Hp 2-2. The significance of the finding and its relationship to structural evolution are also discussed.

  • Length variations in human mitochondrial DNA (mtDNA) offer useful markers in the study of female aspects of human population history. One such length variation is a 9-bp deletion in the small noncoding segment located between the COII and Iysine tRNA genes (COII/tRNA/$^{Lys}$ intergenic region) which usually contain two tandemly arranged copies of a 9-bp sequence (ccccctcta) in human mtDNA. The mtDNA 9-bp deletion and polymorphic variants of expanded 9-bp repeat motif in the intergenic COII/tRNA$^{Lys}$ region have been found at varying frequencies among different human ethnic groups. We have examined the length variation of the mtDNA COII/tRNA$^{Lys}$ intergenic region from a total of 813 individuals in east Asian populations. The occurrence of the 9-bp deletion was found to be relatively homogeneous in northeast Asian populations (Chinese, 14.2%; Japanese, 14.3%: Koreans, 15.5%), with the exception of Mongolians (5.1%). In contrast, Indonesians (25.0%) and Vietnamese (23.2%) of the southeast Asian populations appeared to have relatively high frequencies of the 9-bp deletion. We identified the existence of a new expanded 9-bp repeat motif which likely resulted from a slipped mispairing insertion of six more cytosines in the intergenic COII$^{Lys}$ region. It was present at low frequencies in the Korean (2/349) and Japanese populations (2/147). Based on the results of this study, the Korean population may reflect a close genetic affinity with the Japanese and Chinese populations than the others surveyed east Asian populations.

  • In this study, we developed 15 novel polymorphic simple sequence repeat (SSR) markers by SSR-enriched genomic library construction from Codonopsis lanceolata. We obtained a total of 226 non-redundant contig sequences from the assembly process and designed primer sets. These markers were applied to 53 accessions representing the cultivated C. lanceolata in South Korea. Fifteen markers were sufficiently polymorphic, and were used to analyze the genetic relationships between the cultivated C. lanceolata. One hundred three alleles of the 15 SSR markers ranged from 3 to 19 alleles at each locus, with an average of 6.87. By cluster analysis, we detected clear genetic differences in most of the accessions, with genetic distance varying from 0.73 to 0.93. Phylogenic analysis indicated that the accessions that were collected from the same area were distributed evenly in the phylogenetic tree. These results indicate that there is no correlative genetic relationship between geographic areas. These markers will be useful in differentiating C. lanceolata genetic resources and in selecting suitable lines for a systemic breeding program.

  • Faba bean (Vicia faba L.) is one of the most important legume crops in Egypt. However, production of faba bean is affected by several diseases including fungal diseases. Fusarium wilt incited by Fusarium oxysporum Schlecht. was shown to be the most common wilt disease of faba bean in Assiut Governorate. Evaluation of 16 faba bean genotypes for the resistance to Fusarium wilt was carried out under greenhouse conditions. Three molecular marker systems (inter-simple sequence repeat [ISSR], sequence related amplified polymorphism [SRAP], and simple sequence repeat [SSR]) and a biochemical marker (protein profiles) were used to study the genetic diversity and detect molecular and biochemical markers associated with Fusarium wilt resistance in the tested genotypes. The results showed that certain genotypes of faba bean were resistant to Fusarium wilt, while most of the genotypes were highly susceptible. The percentage of disease severity ranged from 32.83% in Assiut-215 to 64.17% in Misr-3. The genotypes Assiut-215, Roomy-3, Marut-2, and Giza2 were the most resistant, and the genotypes Misr-3, Misr-1, Assiut-143, Giza-40, and Roomy-80 performed as highly susceptible. The genotypes Assiut-215 and Roomy-3 were considered as promising sources of the resistance to Fusarium wilt. SRAP markers showed higher polymorphism (82.53%) compared with SSR (76.85%), ISSR markers (62.24%), and protein profile (31.82%). Specific molecular and biochemical markers associated with Fusarium wilt resistance were identified. The dendrogram based on combined data of molecular and biochemical markers grouped the 16 faba bean genotypes into three clusters. Cluster I included resistant genotypes, cluster II comprised all moderate genotypes and cluster III contained highly susceptible genotypes.

  • A simple AMC (Adaptive Modulation and Coding) technique using ARQ (Automatic Repeat Request) for a MIMO (Multiple Input Multiple Output) system is proposed which does not require the additional feedback. In addition, the proposed AMC technique is different from the conventional technique in the aspect of considering the MCS (Modulation and Coding Scheme) level from the previous packet. The proposed technique can discard fewer amounts of unsuitable packets than the conventional technique. In the proposed system not only same rate control method for transmit antennas but also individual rate control method can be applied. The performance of the proposed technique is verified under a MIMO-OFDM (Orthogonal Frequency Division Multiplexing) system based on WLAN (Wireless Local Area Network), IEEE 802.11a. The results of the computer simulation show that a MIMO system with the proposed technique achieves higher throughput than one with a fixed transmission rate.

  • The white button mushroom (Agaricus bisporus) is one of the most widely cultivated species of edible mushroom. Despite its economic importance, relatively little is known about the genetic diversity of this species. Illumina paired-end sequencing produced 43,871,558 clean reads and 69,174 contigs were generated from five offspring. These contigs were subsequently assembled into 57,594 unigenes. The unigenes were annotated with reference genome in which 6,559 unigenes were associated with clusters, indicating orthologous genes. Gene ontology classification assigned many unigenes. Based on genome data of the five offspring, 44 polymorphic simple sequence repeat (SSR) markers were developed. The major allele frequency ranged from 0.42 to 0.92. The number of genotypes and the number of alleles ranged from 1 to 4, and from 2 to 4, respectively. The observed heterozygosity and the expected heterozygosity ranged from 0.00 to 1.00, and from 0.15 to 0.64, respectively. The polymorphic information content value ranged from 0.14 to 0.57. The genetic distances and UPGMA clustering discriminated offspring strains. The SSR markers developed in this study can be applied in polymorphism analyses of button mushroom and for cultivar discrimination.

  • Percutaneous pulmonary valvuloplasty was performed in 19 patients of congenital pulmonary valve stenosis. Pulmonary annulus diameter was estimated by cross sectional echocardiography and right ventricular cineangiography. The size of balloon dilatation catheter was chosen by the same size of the estimated pulmonary annulus in the first 3 patients and 20 \ulcorner30% greater than the annulus in the last 17 patients. After valvuloplasty a satisfactory results was obtained in most patients. Before dilatation, the right ventricular systolic pressure was 91.7 mmHg[range 58-150 mmHg] and it fell to 49.2mmHg[25-85 mmHg] after dilatation. The transvalvular gradient was 67.7 mmHg[33 \ulcorner120 mmHg] before dilatation and it fell to 23.7mmHg [5 \ulcorner62] after dilatation. Repeat cardiac catheterization has been scheduled in all patients 3 months after the initial valvuloplasty but follow up recatheterization was performed in only two patients; in one of them residual gradient of 50 mmHg was reduced to 30 mmHg by repeat valvuloplasty. The other patient showed no evidence of restenosis with transvalvular gradient of 20 mmHg The balloon used for valvuloplasty was single balloon for the first 10 cases and for the later 10 cases it was replaced by Trefoil balloon which was easier for inflation and deflation. There were no significant complications during and after the procedure. From our results, we conclude that balloon valvuloplasty for congenital pulmonary valve stenosis is the treatment of choice in most patients.

  • These studies are carried out to improve silk availability for anticrease by useing methacrylate monomer polymerization method with in silk fiber. For this purpose, degree of anticrease, stiffness and shrinkage of various silk fabrics, included finish or not, after repeat of washings and polyster fabric was compared as standard. The adopted samples are ; 1. Polyester, Georgette, Woven density…90cm-85g/m 2. Silk, Twill, Degumed, Light, Woven density…90cm-90g/m 3. Silk, Twill, Degumed, Heavy, Woven density…90cm-200g/m 4. Silk, Stain, Degumed, Light, Woven density…90cm-90g/m The reached results are as followings. 1. The results of improving on anticrease by the finished method were about ten per cent increase against their original samples. 2. The light density silks showed satisfactory improve for anticrease, but the heavy one remained as rather poor condition. 3. The results for degree of textile stiffness were investigated to make sure reserve their textile feeling and observed to be good condition upon the finish work. 4. Textile shrinkage after the repeat of soap wash was investigated on indivisual test sample and silk fabrics showed more shrinkage than polyester which it seemed to be tentering shrinkage druning their general finishing processes. 5. The investigation showed that anticrease, stiffness and shrinkage of the sample textile were more or less deteriorated regardless silk or polyester by the repeat of washings. These matters are considered that such results were obtained because of the fiber fatigue nature. 6. The report reached that silk textiles should be used by dry cleaning methed after finish of any resin finish to reserve their improved anticrease nature.

  • It has been well known that the splanchnic nerve block is effective for patients who suffer from intractable upper abdominal pain. However, it is unclear whether the effect of the splanchnic nerve block depends on varied alcoholic concentration. In this study, an attempt was made to use absolute ethanol on patients who recieved a splanchnic nerve block at Severance Hospital during the period from September l990 to April l991. The results are as follows; 1) Among the 33 patients, including 22 males and 1l females, the fifties and sixties were the major age groups. 2) Stomach cancer was the most common underlying disease(13 cases), with pancreatic can- cer next(9 cases). 3) The main locations of pain were the upper abdomen, epigastrium, and entire abdomen in decreasing order. 4) There were 17 cases who had had chemotherapy, and 1l cases of whom had had surgery before the splanchnic nerve block. 5) The volume of alcohol used was 12 ml bilaterally. 6) Among the 33 patients, 15.2% required a second block within two weeks of the first block. One case required a third block. 7) The most common complications of splanchnic nerve block were hypotension(33.3%), occasional transient sharp burning pain, flushing of face, pain on injection site, nausea, vomiting, dyspnea, chest discomfort and diarrhea. 8) The supplemental block most commonly used was a continuous epidural block. It was used both as a diagnostic block and to afford relief from pain before the splanchnic nerve block was done. 9) The interval between the receiving the absolute ethanol block and discharge was within 2 weeks in l5 cases. But, in the patients with poor general health, the interval between the splanchnic nerve block and discharge prolonged. The above results suggest that bilateral splanchnic nerve block done with absolute ethanol after an effective test block with 1% lidocaine under C-arm fluroscopic control is satisfactory and reliable. Still, 26.6% of the patients received a repeat block within 2 weeks. Insufficient spread of ethanol due to its small volume seems to be a major factor in the repeat block. Minimizing the incidence of repeat block remains a problem to be solved.
