in the mouse hippocampus and neostriatum following transient global forebrain ischemia. Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery for 40 min. Ampicillin was administered post-ischemically (for 3 days) and/or pre-ischemically (for 3∼5 days until one day before the onset of ischemia). Pre- and post-ischemic treatment with ampicillin (50 mg/kg/day or 200 mg/kg/day) prevented ischemic neuronal death in the medial CA1 area of... -

대한수의학회 Journal of Veterinary Science 2001, 제 2권 제 2호 10 125-130 (6 pages)
This study was performed to evaluate the effects of nerve growth factor (NGF) upon angiogenesis in the rat cornea, to examine its possible application as an alternative angiogenic inducer and to provide basic data for further studies. Angiogenesis was induced by cornea micropocket assay, as previously described. Eight of thirty two eyes of Sprague-Dawley rats were randomly assigned to one of four groups, namely, a non-NGF group (Group 0), a 0.5 ng of NGF group (Group 0.5), a 1.0 ng of NGF group... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2016, Vol.20 No.2 7 185-192 (8 pages)
Ampicillin, a β-lactam antibiotic, dose-dependently protects neurons against ischemic brain injury. The present study was performed to investigate the neuroprotective mechanism of ampicillin in a mouse model of transient global forebrain ischemia. Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral common carotid artery occlusion for 40 min. Before transient forebrain ischemia, ampicillin (200 mg/kg, intraperitoneally [i.p.]) or penicillin G (6,000 U/kg or 20,000 U/kg,... -
The Neuroprotective Potential of Cyanidin-3-glucoside Fraction Extracted from Mulberry Following Oxygen-glucose Deprivation

In this study, cyanidin-3-glucoside (C3G) fraction extracted from the mulberry fruit (Morus alba L.) was investigated for its neuroprotective effects against oxygen-glucose deprivation (OGD) and glutamate-induced cell death in rat primary cortical neurons. Cell membrane damage and mitochondrial function were assessed by LDH release and MTT reduction assays, respectively. A time-course study of OGD-induced cell death of primary cortical neurons at 7 days in vitro (DIV) indicated that neuronal... -
NMDA Receptor-dependent Inhibition of Synaptic Transmission by Acute Ethanol Treatment in Rat Corticostriatal Slices

The effects of ethanol on corticostriatal synaptic transmission were examined, using extracellular recording and analysis of population spike amplitudes in rat brain slices, to study how acute ethanol intoxication impairs striatal function. Ethanol caused a decrease in population spike amplitudes in a dose dependent manner (50∼200 mM). Pretreatment with picrotoxin, a γ-amino butyric acid (GABA)A receptor antagonist, increased the population spikes but ethanol (100 mM) was still effective in... -
Dopamine Modulates Corticostriatal Synaptic Transmission through Both D1 and D2 Receptor Subtypes in Rat Brain

Striatum has important roles in 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.... -
Inhibitory Modulation of 5-Hydroxytryptamine on Corticostriatal Synaptic Transmission in Rat Brain Slice

Striatum plays a crucial role in the movement control and habitual learning. It receives an information from wide area of cerebral cortex as well as an extensive serotonergic (5-hydroxytryptamine, 5-HT) input from raphe nuclei. In the present study, the effects of 5-HT to modulate synaptic transmission were studied in the rat corticostriatal brain slice using in vitro extracellular recording technique. Synaptic responses were evoked by stimulation of cortical glutamatergic inputs on the corpus... -

areas. In situ hybridization using [35S]UTP-labeled antisense c-fos, cRNA increased c-fos mRNA levels though hippocampal formation, piriform cortex, septum, caudate-putamen, neostriatum, and amygdala within 2 hr. In parallel with the mRNA expression, c-FOS protein immunoreactivity was also observed in the same forebrain areas. In contrast to the seizure activity and widespread neuronal degeneration following a kainate treatment, injections of lidocaine did not produce neuronal death within 3... -

전전두엽(prefrontal cortex)에서 도파민 기능의 저하가 선조체 부위의 도파민 신경계에 어떠한 변화를 초래하는지를 알기 위하여, 흰쥐 내측 전전두피질에 6-hydroxydopamine을 투여한 2주 후에 선조체 부위 인 미상핵-피각과 피질하 조직의 하나인 측좌핵에서 도파민 D1과 D2 수용체의 변화를 자가방사기록법을 이 용하여 측정하였다. 전전두엽에 6-hydroxydopamine을 투여한 2주 후 미상핵-피각과 측좌핵에서의 D1 수용체의 Bmax는 대조군과 통계적인 차이가 없었으며, Kd는 대조군에 비해 통계적으로 유의하게 감소하였다(p<0.01). 6-...
