In the earlier investigations it was shown that muscular exercise augmented the dilator effects of ACh in the vascular bed of the hind leg of dog. To get a closer insight into this phenonenon the effects of acetylcholine on the nutritive blood flow in contracting skeletal muscle in the dog were studied. It was found that i.a. acetylcholine administration raises the nutritive blood flow in the investigated vascular bed within about 30--36 minutes after muscular contractions. The nutritive blood flow during and following muscular contractions induced by stimuli of varying frequency was also investigated.
在早期的研究中发现，肌肉运动增强了乙酰胆碱对狗后肢血管床的舒张作用。为了更深入地了解这一现象，研究了乙酰胆碱对狗收缩骨骼肌中营养性血流的影响。结果发现，肌肉收缩后约30 - 36分钟内，经动脉注射乙酰胆碱可使所研究血管床中的营养性血流增加。还研究了不同频率刺激引起的肌肉收缩期间及之后的营养性血流情况。
