  • 본 연구는 대한민국 공군사관생도들을 대상으로 12주간 복합 트레이닝(유/무산소성 트레이닝, 공간지각 트레이닝)이 Angiotensin Converting Enzyme (ACE) gene polymorphism에 따른 신체조성과 심폐지구력 변화에 미치는 영향을 규명하는데 목적이 있었다. 연구결과, 12주간 복합 트레이닝 후 신체조성은 ACE gene polymorphism에 따라 변화의 차이가 나타나지 않았으며, 심폐지구력은 I allele 집단(II/ID genotype group)이 D allele 집단(DD genotype group)보다 트레이닝의 효과가 높게 나타났다. 본 연구 결과로 볼 때, 복합 트레이닝은 ACE gene polymorphism에 따라 심폐지구력 변화에 다르게 반응하고 있으며, I allele (II/ID genotype group)를 가지고 있는 개체가 더 높은 트레이닝의 효과를 얻을 수 있음을 제시해 주고 있다.

  • 우리 나라 전통발효식품인 된장으로부터 angiotensin 전환효소(angiotensin converting enzyme, ACE) 저해활성이 우수한 균주 SYG3를 분리하여 형태학적, 배양학적, 생리학적인 특성을 조사한 결과 B. pumilus 또는 그 유연균으로 동정되었다. 분리 균주의 ACE 저해물질 생산조건을 알아보기 위해 각종 배양조건에 따른 저해활성을 조사한 결과, 탄소원으로서는 glucose, 질소원으로서는 soybean powder에서 가장 높은 저해활성을 나타내었으며, skim milk와 casein에서도 비교적 높은 저해활성을 나타내었다. Soybean powder 농도에 따른 저해활성은 5%(w/v) 첨가시 가장 높은 저해활성을 나타내었으며. 그 이상의 농도에서는 저해활성의 변화가 거의 없었다. NaCl 농도는 3%(w/v) 첨가시 저해활성이 가장 높은 것으로 나타났으며 배양온도는 $32^{\circ}C$, 초기 pH 7.0에서 가장 높은 저해활성을 나타내었다. 최적배지조건에서의 배양시간에 따른 ACE 저해활성은 배양 36시간에 약 98%로서 최고에 도달하였다.

  • ACE-inhibitory peptides derived from goat's whey hydrolyzed by various proteolytic enzymes were separated and purified for antihypertension materials. The highest ACE-inhibitory activity of goat's whey hydrolysates was 85.5 % by pepsin for 72 hrs. Also the highest ACE-inhibitory activity of goat's whey hydrolysates was F-4 by pepsin for 72 hrs by Sephadex G-25 gel chromatograms. F-4e and F-4ed from F-4 by RP-HPLC to first and second purification were the highest in ACE-inhibitory activity, respectively. The most abundant amino acid was leucine(I 8.54 %) in F-4ed of ACE-inhibitory peptides after second purification. Amino acid sequence of F-4ed of ACE-inhibitory peptides showed Leu-Lys-Asp-Tyr-Gly-GlyVal- Ser-Leu and Leu-Gly-Asp-Gly-Ala-Gly- Asp-Val-Ala-Phe. $IC_{50}$ calibrated in peptic hydrolysates(72 hrs), F-4, F-4e and F-4ed from goat's whey hydrolysates by pepsin for 72 hrs were 33.93, 28.75, 11.74 and 1.09 mg/ml, respectively. From the results of this experiment, goat's whey hydrolysate by pepsin was shown to have ACE-inhibitory activity.

  • This experimental Study was designed to investigate the effects of Acanthopanacis Cortex Extract(ACE) on the immunity, anti-cancer and obesity in mice. The results were as follows; ACE was significantly increased in the proliferation of thymocytes and splenocytes, and NO production from peritoneal macrophages in normal mice. ACE was significantly increased in the proliferation of thymocytes and splenocytes, and NO production from peritoneal macrophages in L1210 cells transplanted mice. ACE was significantly decreased in the proliferation of L1210 cells in L1210 cells transplanted mice. ACE was significantly inhibited body weight and tumor weight in S-180 cells transplanted mice. ACE was significantly increased in the mean survival days in S-180 cells transplanted mice. ACE was significantly decreased in the body weight in rats fed high fat diet. ACE was significantly decreased in the serum total cholesterol level, free fatty acid level, total lipid level, phospholipid level in rats fed high fat diet. According to above results, the authors suggest that ACE is able to be used for the herb of physiological-action.

  • Essential hypertension has been considered as multifactorial disease resulted from the interaction of both environmental and genetic factors. The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure homeostasis. Recently, a homologue of angiotensin I converting enzyme, ACE2 has been focused on as a candidate gene of essential hypertension in the experiments using animal model and human being. In this study, we carried out an association study in order to clarify the relationship between the A 1075G polymorphism in the ACE2 gene and essential hypertension in Korean subjects. Because this polymorphism is located on human chromosome X, the statistical analysis for each gender was performed separately. There were no significant differences in allele distribution of the A 1075G polymorphism in the ACE2 gene between normotensives and hypertensives in the both gender groups, respectively. However, this polymorphism was significantly associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) values in only female groups (P< 0.05). Thus, these results may suggest the probable role of ACE2 gene in the inter-individual susceptibility of female group to blood pressure variability.

  • Angiotensin I-converting enzyme (ACE) inhibitors have generally been very useful to remedy or prevent hypertension. This study describes the extraction and characterization of an ACE inhibitor from the fruiting body of Pholiota adiposa ASI 24012, which can be used as an antihypertensive drug. The maximal ACE inhibitory activity $(IC_{50};0.25mg)$ was obtained when the fruiting body of Pholiota adiposa ASI 24012 was extracted with distilled water at $30^{\circ}C$ for 12 h. After the purification of ACE inhibitor with ultrafiltration, Sephadex G-25 column chromatography, and reverse-phase HPLC, an active fraction with an $IC_{50}$ of 0.044 mg was obtained. The purified ACE inhibitory peptide was a novel pentapeptide, showing very little similarity to other ACE inhibitory peptide sequences. The molecular mass of the purified ACE inhibitor was estimated to be 414 daltons with a sequence of Gly-Glu-Gly-Gly-Pro, and showed a clear antihypertensive effect on spontaneously hypertensive rats (SHR) at a dosage of 1 mg/kg.

  • This study was conducted to screen in vitro angiotensin - I converting enzyme (ACE) inhibitory activities of methanol (MeOH) and aqueous extracts at 20°C and 70°C, respectively, prepared from twenty-six red algae obtained from the coast of Jeju Island in Korea. Among aqueous extracts at 20°C (20AE) from red algae Lomentaria catenata showed the strongest ACE inhibitory activity and Lithophyllum okamurae recorded the second highest activity. From MeOH extract at 20°C (20ME) Ahnfeltiopsis flabelliformis possessed the strongest ACE inhibitory activity. Remarkable activities from MeOH extracts at 70°C (70ME) were observed in Grateloupia filicina, Sinkoraena lancifolia and Grateloupia lanceolata. However, no significant activity was found in aqueous extracts at 70°C (70AE). The IC50 values, which are concentrations required to inhibit 50% activity of ACE, for ACE inhibitory activities of 20AE from Lithophyllum okamurae and L. catenata were 13.78 and 12.21 μg mL–1, respectively. The IC50 values of 20ME from A. flabelliformis and Laurencia okamurae were 13.84 and 106.15 μg mL–1. Those of the 70ME from Bonnemaisonia hamifera, Grateloupia filicina, Sinkoraena lancifolia, G. lanceolata, Gracilaria vermiculophylla and L. okamurae ranged from 25.82 to 124.69 μg mL–1.

  • The polymorphism (insertion, I or deletion, D) of angiotensin converting enzyme (ACE) gene is designated as the presence of a 287 bp Alu repeat. The D/D homozygote carrier is associated with high ACE activity, and this high activity has been implicated with hypertension, coronary artery disease, or diabetic nephropathy. We studied the clinical candidate marker in ACE gene polymorphism using chemical and hematological analysis. The subjects are divided into normotensive and hypertensive groups and ACE genotype in the group was confirmed by PCR method. Chemical analysis was preceded with Hitachi7060, and hematological analysis was performed using Mythic 22. In 116 targeted people, 17 (38.64%) of 44 I/I genotype group are hypertension, 15 (34.09%) in 44 with D/I, but, D/D type in the 28 cases is 15 patients (53.57%) in hypertension. In hypertension group, biochemical analysis (triglyceride, and alkaline phosphatase) and hematological analysis (white blood cell, platelet) are showed high value in D/D genotype of ACE gene. The relationship between hypertension and ACE genotype is the same results as previously reported and we thought that the high laboratory value of white blood cell, platelet, triglycerides, and alkaline phosphatase are also indicator of hypertension in D/D type of ACE.
