It has been shown that QGC isolated and purified from Rumecis folium found protective effects of gastritis and esophagitis which EXT is an ethanol extract of it. We examined acute toxicity and the general pharmacological action of QGC EXT to search for any side effects of it in rats, mice, guinea pigs, and cats. In a single dose toxicity study, QGC EXT didn't show toxicological effects in rats and mice, and the LD50 was over 5 g/kg in both animals, and there were also no changes in weight, feed... -
Changes in Excitability of Neurons in Rat Medial Vestibular Nucleus Following Vestibular Neurectomy
SangWooChun, JeongHeeChoi, ShinHyungLee, ByungRimPark 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 5 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2002, Vol.6 No.6 2 287-291 (5 pages)
Intrinsic excitabilities of acutely isolated medial vestibular nucleus (MVN) neurons of rats with normal labyrinth and with undergoing vestibular compensation from 30 min to 24 h after unilateral vestibular deafferentation (UVD) were compared. In control rats, proportions of type A and B cells were 30 and 70%, respectively, however, the proportion of type A cells increased following UVD. Bursting discharge and irregular firing patterns were recorded from 2 to 12 h post UVD. The spontaneous... -
Temporal Changes in Neuronal Activity of the Bilateral Medial Vestibular Nuclei Following Unilateral Labyrinthectomy in Rats
ByungRimPark, MoonYoungLee, MinSunKim, SungHoLee, HanJoNa, NamYongDoh 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1999, Vol.3 No.5 4 481-490 (10 pages)
To investigate the changes in the responses of vestibular neurons with time during vestibular compensation, the resting activity and dynamic responses of type I and II neurons in the medial vestibular nuclei to sinusoidal angular acceleration were recorded following unilateral labyrinthectomy (ULX) in Sprague-Dawley rats. The unitary extracellular neuronal activity was recorded from the bilateral medial vestibular nuclei with stainless steel microelectrodes of 3∼5 MΩ before ULX, and 6, 24,... -
Excellent field emission properties from carbon nanotube field emitters fabricated using a filtration-taping method
Dong Hoon Shin, Seung Il Jung, Ki Nam Yun, Guohai Chen, Seok-Gy Jeon, Jung-Il Kim, Cheol Jin Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 10 214-217 (4 pages)
A filtration-taping method was demonstrated to fabricate carbon nanotube (CNT) emitters. This method shows many good features, including high mechanical adhesion, good electrical contact, low temperature, organic-free, low cost, large size, and suitability for various CNT materials and substrates. These good features promise an advanced field emission performance with a turn-on field of 0.88 V/mm at a current density of 0.1 mA/cm2, a threshold field of 1.98 V/mm at a current density of 1 mA/cm2,...
