대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2006, Vol.10 No.5 1 223-230 (8 pages)
The emerging concept of the“neurovascular unit”may enable a powerful paradigm shift for neuroscience. Instead of a pure focus on the“neurobiology”of disease, an opportunity now exists to return to a more integrative approach. The neurovascular unit emphasizes that signaling between vascular and neuronal compartments comprise the basis for both function and dysfunction in brain. Hence, brain disorders are not just due to death of neurons, but instead manifested as cell signaling perturbations... -

A large number of factors such as osteotropic hormones, cytokines, or growth factors are related to the bone remodeling which is characterized by the coupling of osteoclast-mediated bone resorption and osteoblast-mediated bone formation. Recent investigations have indicated that cytokines such as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) play a potential role in the bone resorption associated with a variety of pathological conditions such as inflammatory osteolytic disease.... -

In humans and many animal models with chronic progressive renal diseases, angiotensin-converting enzyme (ACE) inhibitor markedly attenuates the progression of nephropathy. Several studies have reported augmented gene expression and redistribution of renal renin in partial nephrectomized rats. Although precise mechanism(s) is not known, the renin-angiotensin system (RAS) may play an important role in the progression of renal diseases. Thus, this study was undertaken to examine the gene... -

칼슘이온은 신경섬유 성장의 중요한 조절인자이나 그 정확한 작용기전은 불명확하다. 세포골격 단백은 in vivo 및 in vitro에서 칼슘의존성 단백분해효소(칼파인)에 의해 신속히 분해되므로, 칼슘이온에 의한 신경섬유의 퇴행에 있어서 칼파인의 관련성을 추구하기위하여, 배양된 해마신경세포에서 칼슘이온 ionophore인 A23187에 의한 신경섬유의 성장억제가 칼파인의 억제제인 EST 및 MDL 28170에 의해 차단되는지를 조사하였다. A23187은 100nM의 농도에서 축삭에는 영향이 없이 수상돌기의 퇴행을 유발하였으나, 300 nM의 농도에서는... -

사람 중성구내의 azurophil granule 내에 존재하는 serine protease인 cathepsin G는 정상 반응에서는 항 박테리아 작용을 나타내는데 관여하지만, 이들의 효소활성이 비정상적으로 증가되었을 때는 오히려 인체 정상 조직을 파괴함으로써 rheumatoid arthritis를 비롯한 여러가지 염증성 질환을 야기시킨다고 알려져 있다. 항염증제로 작용하는데 있어서 prostaglandin 합성을 억제하는 작용 이외에 다른 작용 기전이 있는가 하는것은 대단히 흥미있는 연구 과제이었으므로 neutral protease 중의 하나인 cathepsin G와 이 염증반응에... -

Hydroxyl raical(OH⋅)을 생성하는 것으로 알려진 iron-catalyzed Haber-Weiss rocation에서 superoxide anion (O2-⋅)은 주로 Fe+++을 Fe++로 환원시키는 데에 작용하는 것으로 추정하고 있다. 이러한 OH⋅ 의 역할은 다른 환원제들에 의하여 대체가 가능할 것으로 추측되며 생물계의 환원제의 하나로써 ascorbate가 관심의 대상이 되고 있다. 이에 따라 본 연구에서는 Fe++와 H2O2 존재하에서 OH⋅ 을 생성하는 ascorbate 의 역할을 hyaluronic acid의 변성과 methional로 부터 ethylene 생성에 대한 효과로써... -

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... -
