motor control, habitual learning and memory. It receives glutamatergic inputs from neocortex and thalamus, and dopaminergic inputs from substantia nigra. We examined effects of dopamine (DA) on the corticostriatal synaptic transmission using in vitro extracellular recording technique in rat brain corticostriatal slices. Synaptic responses were elicited by stimulation of cortical glutamatergic inputs on the corpus callosum and recorded in the dorsal striatum. Corticostriatal population spike (PS)...

High extracellular glucose concentration was reported to suppress intracellular Ca2⁢ clearing through altered sarcoplasmic reticulum (SR) function. In the present study, we attempted to elucidate the effects of pyruvate and fatty acid on SR function and reveal the mechanistic link with glucose-induced SR dysfunction. For this purpose, SR Ca2⁢-uptake rate was measured in digitonin-permeabilized H9c2 cardiomyocytes cultured in various conditions. Exposure of these cells to 5 mM...

Effects of antioxidants on the established nephropathy were investigated. The experimental nephropathy was induced in rats by intravenous injection of adriamycin (2 mg/kg). Six weeks later, when proteinuria was apparent, the rats were supplemented with N-acetylcysteine (NAC, 1 g/kg/day) in drinking water for additional 6 weeks. Glomerulosclerosis score and tubulointerstitial injury index were determined by light microscopy. Expression of transforming growth factor (TGF) β1 and laminin β1 was...

Potassium channels in human skin fibroblast have been studied as a possible site of Alzheimer disease pathogenesis. Fibroblasts in Alzheimer disease show alterations in signal transduction pathway such as changes in Ca2⁢ homeostasis and/or Ca2⁢-activated kinases, phosphatidylinositol cascade, protein kinase C activity, cAMP levels and absence of specific K⁢ channel. However, little is known so far about electrophysiological and pharmacological characteristics of...

In the heart, Na⁢-Ca2⁢ exchange (NCX) is the major Ca2⁢ extrusion mechanism. NCX has been considered as a relaxation mechanism, as it reduces global [Ca2⁢]i raised during activation. However, if NCX locates in the close proximity to the ryanodine receptor, then NCX would curtail Ca2⁢ before its diffusion to global Ca2⁢i. This will result in a global [Ca2⁢]i decrease especially during its ascending phase rather than descending phase. Therefore, NCX would...

Very little research has been carried out on safflower seed for the prevention and treatment of the bone deficiency diseases, including osteoporosis, which are supported by scientific evidences. In the present study, 3μl of 0.1% dried crude extract or 2μl of 0.1% dried aqueous fraction were shown to significantly accelerate the rate of differentiation of osteoblast. Also, the crude extract and aqueous fraction increased the [Ca2⁢]i of the cultured osteoblast cells: 3μl of 0.1% dried...

1μM CCCP was used for pretreatment before application of NMDG+, oscillatory decay of [Ca2+]i by NMDG+ was significantly inhibited compared to the control (p＜0.05). In addition, NMDG+-induced increase of [Ca2+]i was highly enhanced by pretreatment with 2μM CCCP by 320⁑93.7%, compared to the control (mean⁑S.E., n=12). From these results, it is concluded that mitochondria might have buffering contribution to the [Ca2+]i increase through regulation of the background NSCC in RAECs.

The present study was undertaken to determine the regulation of heat shock proteins (HSP) in the kidney in hypertension. Two-kidney, one clip (2K1C) or deoxycorticosterone acetate (DOCA)-salt hypertension was induced in male Sprague-Dawley rats. At weeks 1 and 4 after inducing the hypertension, the expression of HSP70, HSP32 and HSP25 was determined in the kidney by Western blot analysis. In 2K1C hypertension, the expression of HSP70, HSP32 and HSP25 was increased in the clipped kidney at both...

Nitric oxide (NO) system has been implicated in a wide range of physiological functions in the nervous system. However, the roleof NO in regulating the neural activity in the gustatory zone of nucleus tractus solitarius (NTS) has not been established. The present study was aimed to investigate the role of NO in the gustatory NTS neurons. Sprague-Dawley rats, weighing about 50 g, were used. Whole cell patch recording and immunohistochemistry were done to determine the electrophysiological...

Mutations in the NF2 tumor suppressor gene cause neurofibromatosis type 2, an autosomal dominant inherited syndrome predisposed to the multiple tumors of the nervous system. Merlin, the NF2 gene product was reported to block Ras-mediated cell transformation and represses Ras-induced expression of cyclin D1. However, the potential mechanism underlying the anti-Ras function of merlin on the cyclin D1 is still unclear. In this study, we investigated whether merlin decreases Ha-ras-induced...
