Spinal cord blood flow (SCBF) was measured in the primate thoracic spinal cord using the 14C-antipyrine autoradiographic technique that allowed clear differentiation between white and gray matter blood flow. Individual SCBF values were obtained for 0.1-sq mm areas of the thoracic cord cross section. White matter blood flow was homogeneous throughout with a mean value of 10.3 +/- 0.2 ml/100 gm/min. Gray-matter flow was more variable with lower values in the dorsal horns and higher values in the central gray and anterior horns. Mean gray-matter flow was 57.6 +/- 2.3 ml/100 gm/min. Arterial pO2 was 123 +/- 2 torr, pCO2 was 40.2 +/- 0.5 torr and pH was 7.327 +/- 0,010. Mean arterial blood pressure was 113 +/- 3 mm Hg and core temperature was 36.4 degrees +/- 0.1 degrees C.
采用14C-安替比林放射自显影技术测量灵长类动物胸段脊髓的脊髓血流量（SCBF），该技术能够清晰区分白质和灰质的血流量。获取胸段脊髓横截面积为0.1平方毫米区域的个体SCBF值。白质血流量在整个区域内均匀，平均值为10.3±0.2毫升/100克/分钟。灰质血流量变化更大，背角值较低，中央灰质和前角值较高。灰质平均血流量为57.6±2.3毫升/100克/分钟。动脉血氧分压为123±2托，二氧化碳分压为40.2±0.5托，pH值为7.327±0.010。平均动脉血压为113±3毫米汞柱，核心体温为36.4摄氏度±0.1摄氏度。
