a sustained decrease of mechanical threshold which was significantly attenuated by topical application of capsaicin onto afferent fiber and intraplantar injection of 1-ethyl-2-benzimidazolinone. NS1619 selectively attenuated the decrease of mechanical threshold induced by charybdotoxin, but not by apamin. Spontaneous flinching and paw thickness were not significantly different after KCa channel blockade. These results suggest that mechanical sensitivity can be modulated by KCa channels on... -

of the action potential, its firing threshold and the resting membrane potential. In this study, whole cell configuration of patch clamp technique had been applied to record the blocking effect of capsaicin, a lipophilic alkaloid, on the delayed rectifier K current in cultured small diameter DRG neurons of adult rat. Capsaicin reduced the amplitude of K current in dose dependent manner, and the concentration-dependence curve was well described by the Hill equation with KD value of... -

및 용매를 화학물질로 30분간 침지한 후, 먼저 열판시험으로 capsaicin군과 그의 saline 대조군 및 전체 용매군과 그의 saline 대조군을 비교하고,그 다음 미부액침시험으로 검사 방법을 바꾸어서 전체 용매군 만을 대상으로 3개월에 걸쳐 매주 실 험하였다. 열판시험 결과는 다양하며 통계적 유의성이 없었고,미부액침시험에서 용매에 침지한 후 4~7주에 잠복기가 통계적으로 유의하게(PC0.005) 감소됨을 보였으며, 이것은 polysorbate 80에 의하는 것으로 생각된다. 이러한 결과는 용매가 열성 통각수용기를 과감작시킬 수 있음을... -

변화를 보였으나 TFR latency의 차이는 없었다. 또한, 0.5 mg/kg의 MK-801를 i.v.로 전처치 하였을 때, intrathecal capsaicin에 의한 TFR latency의 증가와 척수 내 NE의 감소가 모두 억제되었다. 이상의 결과는 capsain이 excitatory aminoacid (EAA)계 - NE계 - 척수 dorsal horn으로 이루어진 동통전달의 하행성 억제계 축의 활성을 항진시켜 진통효과를 가져옴을 보여준다. 또한, capsaicin의 피하 주사시에 진통효과를 볼 수 없음을 말초 동통전달신경의 흥분에 의한 중추 동통전달계 환성의 촉진이 진통 효과를 상쇄함을 암시한다. -
Effect of Capsaicin on Causalgiform Pain in the Rat

of capsaicin to relieve pain with no change in the number of C-fibers and its effective duration for pain relief. Capsaicin has been used extremely as a experimental tool and as topical medications for acute or chronic tissue injuries and partial nerve injury is the main cause of causalgiform pain disorders in humans. Here, the left sciatic nerve was ligated unilaterally at the high level of the thigh to prepare an animal model of this pain condition. The rat developed guarding behavior of the... -

In order to elucidate whether capsaicin applied topically acts as a pain-producing subastance or as a tastant, neuronal activities of the chorda tympani nerve(CN), lingual nerve(LN), solitary tract nucleus(STN), and trigeminal nucleus(TGN) were recorded while thermal and taste stimuli, and capsaicin were being applied topically, and algesics intra-arterially to the tongue of cats anesthetized with α-chloralsoe. In addition, the STN neurons were examined after wheat germ agglutinin-horseradish... -
Expression of KA1 kainate receptor subunit in the substantia gelatinosa of the trigeminal subnucleus caudalis in mice

The KA1 kainate receptor (KAR) subunit in the substantia gelatinosa (SG) of the trigeminal subnucleus caudalis (Vc) has been implicated in the processing of nociceptive information from the orofacial region. This study compared the expression of the KA1 KAR subunit in the SG of the Vc in juvenile, prepubescent and adult mice. RT-PCR, Western blot and immunohistochemistry analyses were used to examine the expression level in SG area. The expression levels of the KA1 KAR subunit mRNA and protein... -

direct excitatory link with low-threshold input to nociceptive neurons. Experiments were performed on male Sprague-Dawley rats weighing 230-280 g. Subcutaneous injection of interleukin 1 beta (IL-1β) (1 ng/10 μL) was used to produce mechanical allodynia and thermal hyperalgesia. Intracisternal administration of bicuculline, a gamma aminobutyric acid A (GABAA) receptor antagonist, produced mechanical allodynia in the orofacial area under normal conditions. However, intracisternal administration... -

This study was performed to investigate whether the spinal cho-linergic and serotonergic analgesic systems mediate the relieving effect of elec-troacupuncture (EA) on oxaliplatin-induced neuropathic cold allodynia in rats. The cold allodynia induced by an oxaliplatin injection (6 mg/kg, i.p.) was evaluated by immersing the rat’s tail into cold water (4oC) and measuring the withdrawal latency. EA stimulation (2 Hz, 0.3-ms pulse duration, 0.2~0.3 mA) at the acupoint ST36, GV3, or LI11 all showed...
