Changes in the electro-encephalogram, and in the electro-oculogram electromyogram, ECG, blood supply, blood pressure, electrical skin activity and neurological/psychiatric findings, were investigated in 100 patients given single administrations of 200 mg of pentoxifylline (BL 191). It is concluded from the changes in the EEG wave patterns that pentoxifylline produces a beneficial effect on the cerebral processes contributing to bio-electrical brain activity. Pentoxifylline can be classed as a substance with microcirculatory/metabolic effects on the brain, which lead to stimulation of psychomotor behaviour.
对单次给予200毫克己酮可可碱（BL 191）的100名患者的脑电图、眼电图、肌电图、心电图、血液供应、血压、皮肤电活动及神经/精神学表现的变化进行了研究。根据脑电图波形的变化得出结论，己酮可可碱对有助于脑生物电活动的大脑过程产生有益作用。己酮可可碱可归类为对大脑具有微循环/代谢作用的物质，可导致精神运动行为受到刺激。
