CG200745 is a novel inhibitor of histone deacetylases (HDACs), initially developed for treatment of various hematological and solid cancers. Because it is water-soluble, it can be administered orally. We hypothesized that the HDAC inhibitor, CG200745, attenuates cardiac hypertrophy and fibrosis in deoxycorticosterone acetate (DOCA)-induced hypertensive rats. For establishment of hypertension, 40 mg/kg of DOCA was subcutaneously injected four times weekly into Sprague-Dawley rats. All the rats... -
High Glucose Induces Connective Tissue Growth Factor Expression and Extracellular Matrix Accumulation in Rat Aorta Vascular Smooth Muscle Cells Via Extracellular Signal-Regulated Kinase 1/2

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2013, Vol.17 No.4 8 307-314 (8 pages)
Connective tissue growth factor (CTGF) is a potent pro-fibrotic factor, which is implicated in fibrosis through extracellular matrix (ECM) induction in diabetic cardiovascular complications. It is an important downstream mediator in the fibrotic action of transforming growth factor Ղ (TGFՂ) and is potentially induced by hyperglycemia in human vascular smooth muscle cells (VSMCs). Therefore, the goal of this study is to identify the signaling pathways of CTGF effects on ECM... -

Diabetes mellitus is associated with vascular complications, including an impairment of vascular function and alterations in the reactivity of blood vessels to vasoactive substances in various vasculature. In the present study, the authors have observed endothelin-B (ETB) receptor agonist-induced relaxation in precontracted mesenteric arterial segments from streptozotocin (STZ)-induced diabetic rats, which was not shown from control rats or in other arterial segments from diabetic rats.... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1999, Vol.3 No.4 2 375-382 (8 pages)
Growing evidence indicates that enhanced generation or actions of nitric oxide (NO) are implicated in the pathogenesis of hypertension in spontaneously hypertensive rats and diabetic nephropathy in streptozotocin (STZ)-induced diabetic rats. We investigated whether inducible nitric oxide synthase (iNOS) expression in STZ-induced diabetic rats is responsible for the alterations of vascular reactivity. Diabetic state was confirmed 28 days after injection of STZ (i.p) in rats by measuring blood... -

To investigate the mechanisms of increased endothelium-dependent contraction by acetylcholine in hypertensive rats, the relationship between endothelium-dependent contraction by acetylcholine and blood pressure was studied in spontaneously hypertensive rats (SHR), one-kidney, one clip Goldblatt hypertension (1K,1C-GBH) rats, and Wistar-Kyoto rats (WKY). SHR were treated orally with enalapril or nicardipine in order to prevent development of hypertension or suppress the developed hypertension.... -

This study was designed to test whether or not 1) ischemia-reperfusion attenuates endothelium-dependent relaxation of coronary arteries and 2) preconditioning protects the arterial endothelium from ischemia-reperfusion injury. In anesthetized open chest rabbits, branches of the left circumflex artery were exposed to different combinations of the experimental conditions; ischemia (15 minutes), ischemia (15 minutes)-reperfusion (10 minutes), preconditioning ischemia, and pre-conditioning fellowed... -

Endothelium-derived relaxing factor (EDRF) activates guanylate cyclase which mediates the formation of cGMP from GTP in vascular smooth muscle. It is well known that endothelium-dependent relaxation is impaired in spontaneously hypertensive rats (SHR). However, it is still unknown whether the impaired endothelium-dependent relaxation in SHR results from the reduced release of EDRF or from the decrease of vascular response to EDRF. We investigated the effects of cGMP on the contractility and Ca... -

We investigated the alterations in basal tone of aortic strips by changing the Ca concentration, basal 45Ca uptake and 3H-nitrendipine binding of the single cells of aortic smooth muscles in the spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats. While the basal tone of the aortic strips in WKY rats was not affected by alteration of Ca concentration, that in SHR was decreased by the removal of Ca from the bath solution and was recovered by the restoration of Ca to normal levels.... -

Obesity is a critical risk factor for the hypertension. Although angiotensin II (Ang II) in obese individuals is known to be upregulated in obesity-induced hypertension, direct evidence that explains the underlying mechanism for increased vascular tone and consequent increase in blood pressure (BP) is largely unknown. The purpose of this study is to investigate the novel mechanism underlying Ang II-induced hyper-contractility and hypertension in obese rats. Eight-week old male Sprague-Dawley... -

본 연구의 목적은 2-kidney 1 clip (2K-1C) 신혈관성 고혈압흰쥐에서 심방이뇨펩이드의 혈관 이완작용의 기전을 규명하고 정상혈압흰쥐에서의 혈관이완작용과 비교하는 것이다. 2K-1C 신혈관성 고혈압흰쥐는 정상혈압흰쥐에 비하여 평균동맥압의 유의한 상승과 혈장레닌활성의 증가가 관찰되었다. 2K-1C 신혈관성 고혈압흰쥐의 대동맥에서 norepinephrine (NE)의 수축력의 감수성 및 최대 수축력이 정상혈압흰쥐의 대동맥보다 증가하였다. 심방이뇨펩타이드는 NE에 의한 수축을 농도-의존적으로 각각의 혈압군에서 억제하였다. 그러나,... -

Propylthiouracil(PTU)을 4주 및 12주간 투여한 흰쥐의 대동맥을 적출하여 혈관수축제와 이완제에 대한 반응을 관찰하여 다음과 같은 결과를 얻었다. PTU를 처치한 실험군에서는 대조군에 비해 현저한 체중저하와 혈중 갑상선호르몬의 감소를 보였다. PTU를 처치한 흰쥐의 대동맥에 대한 norepinephrine (NE)과, calcium및 potassium 이온에 의한 최대수축 반응은 대조군에 비하여 유의하게 감소되었다. 그러나 NE에 대한 중간유효량은 증가되었으나, calcium이온에 대한 중간 유효량은 유의한 차이가 없었다. 그리고 acetylcholine,... -

가토흉부대동백근에서 MeB와 gentian violet는 용량-의존성 수축반응을 일으켰으나 evans blue와 eosine yellowish는 전혀 수축반응을 일으키지 못하였다. MeB는 돼지 장간막 동맥에서도 용량-의존성 수축반응을 일으켰다. 양표본에서 MeB 10-4 M의 단회투여는 수축반응에 이어 이완반응이 나타나는 양상성 반응을 일으켰으나, tyramine은 지속적인 수축반응을 일으켰다. Tyramine의 수축반응은 반복적이었으나 MeB의 그것은 일차 수축반응 후 3 ~ 5시간 후까지도 반복되지 않았다. Tyramine 10-4 M의 최대 수축반응 상태에서 MeB 10-4... -

This study highlights a novel method and mechanism for the rapid and effective milling of carbon fibers (CFs) in silicon carbide (SiC) powder, and also the dispersion of CFs in SiC powder. The composite powders were prepared by chopping and exfoliation of CFs, and ball milling of CFs and SiC powder in isopropyl alcohol. A wide range of CFs loading, from 10 to 50 vol%, was studied. The milling of CFs and SiC powder was checked by measuring the average particle size of the composite powders. The... -
