Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

In view of the effect of $\beta_2$-Adrenergic receptors ($\beta_2$-AR) as a risk factor for essential hypertension, we investigated the Fnu4HI and MnlI RFLPs of $\beta_2$ -AR gene in the Korean patients with essential hypertension and normal controls. There were no significant differences in the allele and genotype of these polymorphisms between normotensive and essential hypertensive subjects. In ethnic comparison, the allele frequencies of these three sites contained Nde I RFLP reported the association with essential hypertension in Korean population previously, were very different from those of other ethnic populations studied. The significant linkage disequilibrium was detected only in hypertensive group between Nde I and Fnu4HI sites. The Fnu4HI RFLP was also significantly associated with plasma triglyceride (TG) level. Therefore, our results suggest that the significant association between Fnu4HI variation in the human $\beta_2$-AR gene and plasma TG level may reflect the potential role of human $\beta_2$-AR gene as one of the genetic components for cardiovascular risk.

Bae, Joon-Seol,Kang, Byung-Yong,Kim, Ki-Tae,Shin, Jung-Hee,Lee, Chung-Choo The Korean Society for Integrative Biology 2001 Korean journal of biological sciences Vol.5 No.4

Hypertension is a complex disease with strong genetic influences. Essential hypertension has been shown to be associated with insulin resistance. To clarify the genetic basis of insulin resistance in Hypertension, case-control association studies were performed to examine candidate genes for insulin resistance in hypertension. Polymorphisms investigated were the BstO I polymorphism of the $\beta$3-adrenergic receptor (ADRB3) gene, the Xba I Polymorphism of the glycogen synthase (GSY) gene, the Dde I polymorphism of the protein phosphatase 1 G subuit (PP1G) gene, the BstE II polymorphism of the glucagon receptor (GCG-R) gene, the Pst 1 polymorphism of the insulin (INS) gene and the Acc I polymorphism of the glucokinase (GCK) gene. No significant differences were observed in the distribution of alleles and genotypes of the ADRB3, GSY PP1G, GCG-R, INS, and GCK genes between hypertensive and normotensive groups. Although the frequencies in each of these polymorphisms were not significantly different between essential hypertensive and normotensive individuals, our results may provide additional information for linkage analysis and associative studies of disorders in carbohydrate metabolism or in cardiovascular disease.

BAE, JOON SEOL,PASAJE, CHARISSE FLERIDA A.,PARK, BYUNG LAE,CHEONG, HYUN SUB,KIM, JEONG-HYUN,UH, SOO-TAEK,PARK, CHOON-SIK,SHIN, HYOUNG DOO Spandidos Publications 2013 MOLECULAR MEDICINE REPORTS Vol.7 No.3

<P>Nasal polyps are abnormal lesions arising mainly from the nasal mucosa and paranasal sinuses. Since the human class?II, major histocompatibility complex, transactivator (CIITA) is a positive regulator of class?II, major histocompatibility complex gene transcription, the CIITA gene is thought to be involved in the presence of nasal polyps in asthma and aspirin hypersensitive patients. To investigate the association between CIITA and nasal polyposis, 18?single nucleotide polymorphisms (SNPs) were genotyped in 467?asthmatics who were classified into 158?aspirin-exacerbated respiratory disease (AERD) and 309?aspirin-tolerant asthma (ATA) subgroups. Differences in the frequency distribution of CIITA variations between polyp-positive cases and polyp-negative controls were determined using logistic analyses. Initially, a total of 9?CIITA variants were significantly associated with the presence of nasal polyps in the overall asthma, AERD and ATA groups [P=0.001-0.05, odds ratio (OR)=0.53-2.35 in the overall asthma group; P=0.01-0.02, OR=2.45-2.66 in the AERD group; P=0.001?0.05, OR=0.45-2.61 in the ATA group using various modes of genetic inheritance]. One the variations (rs12932187) retained this association after multiple testing corrections (Pcorr=0.01) in the overall asthma group. In addition, two variations (rs12932187 and rs11074938) were associated with the presence of nasal polyps following multiple testing corrections (Pcorr=0.02?and?0.04, respectively) in the ATA group. These novel findings suggest that rs12932187 and rs11074938 may constitute susceptibility markers of inflammation of the nasal passages in asthma patients.</P>

Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

<P>Schizophrenia is a serious mental disorder that is affected by genetic and environmental factors. As the disease has a high heritability rate, genetic studies identifying candidate genes for schizophrenia have been conducted in various populations. The gene for human Ran???binding protein 9 (RANBP9) is a newly discovered candidate gene for schizophrenia. As RANBP9 is a small guanosine???5'???triphosphate???binding protein that interacts with the disrupted in schizophrenia 1 protein, it is considered to be an important molecule in the pathogenesis of schizophrenia. However, to date, no study has examined the possible association between the genetic variations of RANBP9 and the risk of schizophrenia. In the present study, it was hypothesized that RANBP9 variations may influence the risk of schizophrenia. In order to investigate the association between RANBP9 polymorphisms and the risk of schizophrenia and smooth pursuit eye movement (SPEM) abnormalities, a case???control association analysis was performed. Using a TaqMan assay, five single???nucleotide polymorphisms and an insertion/deletion variation within the start codon region of RANBP9 were genotyped. Five major haplotypes were identified in 449 patients with schizophrenia and 393 unrelated healthy individuals as controls (total, n=842). However, the association analyses revealed no associations between all genetic variants and schizophrenia and SPEM abnormality. To the best of our knowledge, this is the first study to investigate an association between RANBP9 polymorphisms and schizophrenia and SPEM abnormality. The findings of allele frequencies and association results in this study may aid in further genetic etiological studies in schizophrenia in various populations.</P>

The Human PTK6 Interacts with a 23-kDa Tyrosine-Phosphorylated Protein and is localized in Cytoplasm in Breast Carcinoma T-47D Cells

Bae, Joon-Seol,Lee, Seung-Thek Korean Society for Biochemistry and Molecular Biol 2001 Journal of biochemistry and molecular biology Vol.34 No.1

The human PTK6 (also known as Brk) polypeptide, which is deduced from its full-length cDNA, represents a non-receptor protein tyrosine kinase (PTK). It contains SH3, SH2, and tyrosine kinase catalytic domains that are closely related to Src family members. We generated an antihuman PTK6 antibody by immunizing rabbits with a PTK6-specific oligopeptide conjugated to BSA, which corresponds to 11 amino acid residues near the C-terminus. An immunoblot analysis with the antibody detected an expected 52-kDa band in various mammalian transformed cell lines. Immunoprecipitation and immunoblot analyses demonstrated that PTK6 is phosphorylated on the tyrosine residues) and interacts with approximately a 23-kDa tyrosine-phosphorylated polypeptide (most likely a substrate of PTK6) in breast carcinoma T-47D cells. An immunofluorescence analysis demonstrated that PTK6 is localized throughout the cytoplasm of T-47D cells. These results support a possible role for PTK6 in the intracellular signal transduction through tyrosine phosphorylation.

Bae, Joon-Seol,Kang, Byung-Yong,Kim, Ki-Tae,Shin, Jung-Hee,Lee, Chung-Choo Korean Environmental Mutagen Society 2001 한국환경성돌연변이·발암원학회지 Vol.21 No.2

$\beta$$_2$-Adrenergic receptors($\beta$$_2$-AR) contribute to cardiovascular regulation by influencing several functions and a several studies suggest that a decreased function of the $\beta$$_2$-AR may be involved in essential hypertension. We investigated the Arg16Gly mutation of $\beta$$_2$-AR gene, which show enhanced agonist-promoted downregulation of the receptor and yielded different results in terms of association with essential hypertension. We studied the relationship between genetic variation in the $\beta$$_2$-adrenergic receptor gene and hypertension in a Korean population using Nde I restriction fragment length polymorphism (RFLP) analysis. There were significant differences in allele and genotype frequencies between essential hypertensive and normotensive group (Odds ratio(CI) = 1.71 (1.09-2.70)). Therefore, our result suggests that the Nde I RELP of the $\beta$$_2$-adrenergic receptor gene may be useful as a genetic marker in hypertension diagnostics in Korean population.

β₂-adrenergic receptors (β₂-AR) contribute to cardiovascular regulation by influencing several functions and a several studies suggest that a decreased function of the β₂-AR may be involved in essential hypertension. We investigated the Arg16Gly mutation of β₂-AR gene, which show enhanced agonist-promoted downregulation of the receptor and yielded different results in terms of association with essential hypertension. We studied the relationship between genetic variation in the b2-adrenergic receptor gene and hypertension in a Korean population using Nde I restriction fragment length polymorphism (RFLP) analysis. There were significant differences in allele and genotype frequencies between essential hypertensive and normotensive group (Odds ratio(CI) = 1.71 (1.09-2.70)). Therefore, our result suggests that the Nde I RFLP of the β₂-adrenergic receptor gene may be useful as a genetic marker in hypertension diagnostics in Korean population.
