Significant evidence supports the role of the vestibular system in the regulation of blood pressure during postural movements. In the present study, the role of the vestibulo-spino-adrenal (VSA) axis in the modulation of blood pressure via the vestibulosympathetic reflex was clarified by immunohis-tochemical and enzyme immunoassay methods in conscious rats with sinoaortic denervation. Expression of c-Fos protein in the intermediolateral cell column of the middle thoracic spinal regions and blood... -

The X-ray synchrotron is quite different from conventional radiation sources. This technique may expand the capabilities of conventional radiology and be applied in novel manners for special cases. To evaluate the usefulness of X-ray synchrotron radiation systems for real time observations, mouse fetal skeleton development was monitored with a high resolution X-ray synchrotron. A non-monochromatized X-ray synchrotron (white beam, 5C1 beamline) was employed to observe the skeleton of mice under... -

Orthostatic hypotension (OH) is associated with symptoms including headache, dizziness, and syncope. The incidence of OH increases with age. Attenuation of the vestibulosympathetic reflex (VSR) is also associated with an increased incidence of OH. In order to understand the pathophysiology of OH, we investigated the physiological characteristics of the VSR in the disorder. We applied sodium nitroprusside (SNP) to conscious rats with sinoaortic denervation in order to induce hypotension.... -

The effects of fetal mesencephalic cell grafts on the restoration of nigrostriatal dopaminergic function were studied in the intrastriatal 6-hydroxydopamine-lesioned rats. Four weeks after lesioning, transplantation of ventral mesencephalic cells from embryonic day 14 fetuses showed the number of tyrosine hydroxylase (TH) positive cells and fiber outgrowth in the grafted striatum, and significantly ameliorated symptomatic motor behavior of the animals, as determined by apomorphine-induced... -

The present study was carried out to determine the effects of cocaine (0.25, 1.0, 10.0 mg/kg, i.p.) on the interactions between spontaneously active neurons within ensembles of simultaneously recorded neurons in the primary somatosensory cortex (Sl, n= 20) and the ventroposterolateral (VPL, n= 16) thalamic nucleus of awake rats. Spike triggered cross correlation histograms were constructed between pairs of simultaneously recorded neurons. Among 101 neuronal pairs analyzed, 22.7% showed... -

of reformatted images, a cross sectional histogram, maximum intensity projection and shaded surface display. For the cine scans, optimal times were a 9-sec delay time post IV injection in the arterial phase, and an 18-sec delay time post IV injection in the venous phase. A nine-sec delay time was acceptable for the imaging of the canine hepatic arteries by CT angiography. After completion of arterial phase scanning, venous structures of the liver were well visualized as seen on the venous phase. -

Pro-inflammatory cytokine and brain-derived neurotrophic factor (BDNF) are modulated in post-traumatic stress disorder (PTSD). This study investigated the effects of ibuprofen (IBU) on enhanced anxiety in a rat model of PTSD induced by a single prolonged stress (SPS) procedure. The effects of IBU on inflammation and BDNF modulation in the hippocampus and the mechanisms underlying for anxiolytic action of IBU were also investigated. Male Sprague-Dawley rats were given IBU (20 or 40 mg/kg, i.p.,... -
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... -

연구목적： 정신분열증 환자에서 뇌혈류량은 나이, 성별, 이환기간, 임상양상 등에 영향을 받는다. 또한 약리학적 상태 도 고려해야 할 중요한 요소이다. 그러나 항정신병약물 비투여(drug-free) 정신분열증 환자군과 전혀 약물 을 복용하지 않은 환자군(drug-naive) 사이의 상대적 뇌혈류량에 대한 유용한 자료는 거의 없다. 이런 상 태에서 많은 연구들이‘항정신병약물 비노출군과 비투여군의 상대적 뇌혈류량 양상이 동일할 것이다.’라는 가정에서 두 군 모두를‘현재 약물을 복용하고 있지 않은(unmedicated) ’정신분열증 환자에... -

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-...
