The concentrations of homovanillic acid (HVA) and 5-hydroxyindole-acetic acid (5-HIAA) were measured in five cases with partial or complete block of CSF circulation, at various levels. Determinations were made in both a lumbar and a cisternal, or `mixed', sample obtained during pneumoencephalography. Most of the HVA appears to enter the ventricular system at the lateral ventricles, whereas much of the 5-HIAA in CSF originates in lower neuronal structures, including the spinal cord. The spinal contribution to the 5-HIAA content of lumbar CSF is of the order of 23-37%.
对5例不同程度脑脊液循环部分或完全受阻的患者,测定了高香草酸(HVA)和5-羟吲哚乙酸(5-HIAA)的浓度。在气脑造影期间获取的腰椎和脑池或“混合”样本中进行了测定。大部分HVA似乎在侧脑室进入脑室系统,而脑脊液中的大部分5-HIAA起源于较低的神经结构,包括脊髓。脊髓对腰椎脑脊液中5-HIAA含量的贡献约为23%-37%。
