The Pogo mouse is an autosomal recessive ataxic mutant that arose spontaneously in the inbred KJR/MsKist strain derived originally from Korean wild mice. The ataxic phenotype is characterized by difficulty in maintaining posture and side to side stability, faulty coordination between limbs and trunk, and the consequent inability to walk straight. In the present study, the cerebellar concentrations of glutamate and GABA were analyzed, since glutamate is a most prevalent excitatory... -

The Relaxant Effect of Propofol on Isolated Rat Intrapulmonary Arteries
GuangyanZhang, JianxiuCui, YijingChen, JueMa 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 5 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2014, Vol.18 No.5 4 377-381 (5 pages)
Propofol is a widely used anesthetic. Many studies have shown that propofol has direct effects on blood vessels, but the precise mechanism is not fully understood. Secondary intrapulmonary artery rings from male rats were prepared and mounted in a Multi Myograph System. The following constrictors were used to induce contractions in isolated artery rings: high K+ solution (60 mmol/L); U46619 solution (100 nmol/L); 5-hydroxytryptamine (5-HT; 3 μmol/L); or phenylephrine (Phe; 1 μmol/L). The... -
Multiple Effects of a Novel Epothilone Analog on Cellular Processes and Signaling Pathways Regulated by Rac1 GTPase in the Human Breast Cancer Cells

The epothilones are a class of microtubule inhibitors that exhibit a strong antitumor activity. UTD2 is a novel epothilone analog generated by genetic manipulation of the polyketide biosynthetic gene cluster. This study investigated the effects of UTD2 on the actin cytoskeleton and its critical regulators, and the signaling pathways which are essential for cell motility, growth and survival in MCF-7 breast cancer cells. Results showed that UTD2 inhibited the cellular functions of actin... -
The Effect of LidocaineㆍHCl on the Fluidity of Native and Model Membrane Lipid Bilayers
Jun-SeopPark, Tae-SangJung, Yang-HoNoh, Woo-SungKim, Won-IckPark, Young-SooKim, In-KyoChung, UyDongSohn, Soo-KyungBae, Moon-KyoungBae, Hye 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages

The purpose of this study is to investigated the mechanism of pharmacological action of local anesthetic and provide the basic information about the development of new effective local anesthetics. Fluorescent probe techniques were used to evaluate the effect of lidocaineㆍHCl on the physical properties (transbilayer asymmetric lateral and rotational mobility, annular lipid fluidity and protein distribution) of synaptosomal plasma membrane vesicles (SPMV) isolated from bovine cerebral cortex, and... -
The Effect of Methanol on the Structural Parameters of Neuronal Membrane Lipid Bilayers
Hyung-JinJoo, Shin-HoAhn, Hang-RaeLee, Sung-WooJung, Chang-WonChoi, Min-SeokKim, Moon-KyoungBae, In-KyoChung, Soo-KyoungBae, Hye-OckJang, 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages

The structures of the intact synaptosomal plasma membrane vesicles (SPMVs) isolated from bovine cerebral cortexs, and the outer and the inner monolayer separately, were evaluated with 1,6-diphenyl- 1,3,5-hexatriene (DPH) and 1,3-di(1-pyrenyl)propane (Py-3-Py) as fluorescent reporters and trinitrophenyl groups as quenching agents. The methanol increased bulk rotational and lateral mobilities of SPMVs lipid bilayers. The methanol increased the rotational and lateral mobilities of the outer... -
The Development of Phasic and Tonic Inhibition in the Rat Visual Cortex
Hyun-JongJang, Kwang-HyunCho, , Sung-WonPark, Myung-JunKim, ShinHeeYoon, Duck-JooRhie 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages

Gamma-aminobutyric acid (GABA)-ergic inhibition is important in the function of the visual cortex. In a previous study, we reported a developmental increase in GABAA receptor-mediated inhibition in the rat visual cortex from 3 to 5 weeks of age. Because this developmental increase is crucial to the regulation of the induction of long-term synaptic plasticity, in the present study we investigated in detail the postnatal development of phasic and tonic inhibition. The amplitude of phasic... -
Provinol Inhibits Catecholamine Secretion from the Rat Adrenal Medulla
Jung-HeeLee, Yu-SeungSeo, Dong-YoonLim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 11 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2009, Vol.13 No.3 14 229-239 (11 pages)
The aim of the present study was to examine the effect of provinol, which is a mixture of polyphenolic compounds from red wine, on the secretion of catecholamines (CA) from isolated perfused rat adrenal medulla, and to elucidate its mechanism of action. Provinol (0.3∼3Ռg/ml) perfused into an adrenal vein for 90 min dose- and time-dependently inhibited the CA secretory responses evoked by ACh (5.32 mM), high K＋ (a direct membrane-depolarizer, 56 mM), DMPP (a selective neuronal nicotinic... -
Neurovascular Mechanisms in Stroke, Neurodegeneration and Recovery

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... -

Iron(II)에 의한 마이크로좀의 지질 과산화에 미치는 quercetin과 rutin의 억제 효과를 iron의 산화중에서 생성되는 산소 라디칼에 대한 제거 작용과 iron에 대한 킬레이트 작용에 관하여 관찰하였다. Fe2+ 단독에 의한 지질 과산화는 quercetin 또는 rutin에 의하여 용량에 따라 현저하게 억제되었다. Fe2+의 존재하에서 ascorbate또는 NADPH에 의한 지질 과산화는 quercetin과 rutin에 의하여 거의 완전히 억제되었다. Fe2+의 과산화 작용은 SOD와 DABCO에 의하여 억제되었고 catalase, DMSO와 mannitol에 의하여 약간 억제되었다....
