Arachnoiditis was produced experimentally in male albino ICR mice by intrathecal injection of meglumine iocarmate . A control group received intrathecal injection of an electrolyte solution resembling CSF. Eight weeks after injection, the brains and spinal cords were removed for brain beta-endorphin and spinal cord met-enkephalin measurement by radioimmunoassay, and the dural sacs were removed for histologic examination to confirm the presence or absence of arachnoiditis. Brain beta-endorphin content was significantly reduced and spinal-cord enkephalin concentration was significantly elevated in iocarmate-treated animals. The dura and arachnoid in the treated mice were thickened and infiltrated with lymphocytes. These studies indicate that arachnoiditis alters endogenous polypeptide concentrations.

Altered concentrations of brain beta endorphin and spinal cord encephalin have been reported in mice with iatrogenic arachnoiditis. We measured beta-endorphin concentration in cerebrospinal fluid (CSF) in normal monkeys and in monkeys with various degrees of arachnoiditis resulting from myelography and spinal surgery and found a significant negative correlation between the arachnoiditis score and the lumbar CSF beta-endorphin concentration. This study suggests that an assay of CSF beta endorphin can be used to detect the alterations in neurotransmitters in arachnoiditis.
