We measured β-endorphin in cat cerebrospinal fluid (CSF) using a competitive enzyme linked immunosorbent assay. The amount of antibodies reacting competitively with β-endorphin bound to a solid phase was determined using biotin-anti-IgG and avidin-alkaline phosphatase. The minimal detection limit was approximately 1.5 fmol/well. With this assay systen, β-endorphin-like immnoreactivities (ED-ir) in cat CSF were measured. Postoperative ED-ir levels decreased gradually from 0.68 to 0.24 pmol/ml 3 hr later, while the respiratory rate reciprocally increased. The electrical stimulations of thin-fiber muscular afferents, however, did not induce any consistent changes in ED-ir.
