The study aim was to investigate the antihypertensive effect after oral supplementation of dried radish leaves powder (DRLP). Angiotensin-converting enzyme (ACE) activity was measured by spectrophotometric assay. The systolic blood pressure (SBP) was measured in spontaneously hypertensive (SHR) and ...

혈압의 조절 체계는? | 혈압은 주로 레닌-안지오텐신 체계 (renin angiotensin system, RAS)와 바소프레신 (vasopressin) 체계에 의해서 조절된다. RAS에서 안지오텐신 I은 안지오텐신 전환효소 (angiotensin converting enzyme, ACE)의 작용에 의해 안지오텐신 II와 디펩타이드인 His-Leu으로 분해된다. | |
RAS에서 안지오텐신 I은 어떤 작용에 의해 안지오텐신 II와 디펩타이드인 His-Leu으로 분해되는가? | 혈압은 주로 레닌-안지오텐신 체계 (renin angiotensin system, RAS)와 바소프레신 (vasopressin) 체계에 의해서 조절된다. RAS에서 안지오텐신 I은 안지오텐신 전환효소 (angiotensin converting enzyme, ACE)의 작용에 의해 안지오텐신 II와 디펩타이드인 His-Leu으로 분해된다. 안지오텐신 II는 혈관을 둘러싼 근육을 수축시키고, 동시에 ACE는 kinin-kallikrein 체계에서 혈관을 이완시키는 bradykinin을 불활성화시켜 혈압을 상승시킨다. | |
고혈압 치료를 위해 화학적으로 합성된 약제들의 장기복용은 어떤 부작용을 초래하는가? | 고혈압 치료를 위해 화학적으로 합성된 약제들이 사용되는 데 중등도 이상의 고혈압 치료는 이뇨제, β-차단제, 교감신경 억제제, 혈관 확장제, 칼슘 길항제 및 ACE 저해제가 사용된다. 그러나 이들 약물의 장기복용은 혈액 점도 증가, 칼륨을 비롯한 전해질의 불균형, 신장등의 장기 손상, 심부전증 악화등의 부작용을 초래하므로,11) 고혈압과 관련된 심혈관계 질환을 예방하거나 완화시키기 위해 식용 식물의 성분을 이용하고자 하는 연구들이 진행되어 왔다.12-15) 채소류는 항암, 항산화, 지질대사개선효과 및 다량의 섬유소로 인한 장기능 개선효과등의 기능을 갖고 있음이 보고되었고, 국내산 산채류 추출물의 항산화 효과 등 채소의 기능성 물질 및 생리적 효능에 대한 연구가 보고되고 있어 무청도 생리활성이 있음이 기대되는 식용 채소이다. |
