Abstract
The primary responses of the dental areas of the brain cortex in anesthetized rabbits were recorded to demonstrate that application of the alpha-adrenomimetic noradrenaline and beta-adrenolytic propranolol to the cortex suppressed, while application of the beta-adrenomimetic isadrin and alpha-adrenolytic phentolamine potentiated the electrical responses to nociceptive stimulation of the dental pulp. It was found that phentolamine exerted dissimilar effects.
摘要
记录了麻醉兔大脑皮层牙齿区域的初级反应，以证明向皮层应用α-肾上腺素能激动剂去甲肾上腺素和β-肾上腺素能阻滞剂普萘洛尔会抑制反应，而应用β-肾上腺素能激动剂异他林和α-肾上腺素能阻滞剂酚妥拉明会增强对牙髓伤害性刺激的电反应。发现酚妥拉明产生了不同的作用。
