The effect of chemical stimulation of the central nervous system on glucoregulation was studied in pigeons (Columba livia). Adrenaline (30 nmol), noradrenaline (30 or 80 nmol) and carbachol (27 nmol) were injected in 1 microliter NaCl directly into the lateral ventricle and changes in blood glucose concentration were measured. The intraventricular injection of adrenaline resulted in rapid hyperglycemia, whereas the injection of either carbachol or noradrenaline into the lateral ventricle did not cause any significant changes in blood glucose concentration. These results suggest that adrenaline-containing neurons may be involved in central mechanisms controlling blood glucose concentration in the pigeon.
在鸽子（家鸽）身上研究了中枢神经系统化学刺激对葡萄糖调节的影响。将肾上腺素（30纳摩尔）、去甲肾上腺素（30或80纳摩尔）和卡巴胆碱（27纳摩尔）以1微升氯化钠溶液的形式直接注入侧脑室，并测量血糖浓度的变化。脑室内注射肾上腺素导致快速高血糖，而向侧脑室内注射卡巴胆碱或去甲肾上腺素均未引起血糖浓度的任何显著变化。这些结果表明，含肾上腺素的神经元可能参与鸽子体内控制血糖浓度的中枢机制。
