Popis: We investigated the pathological changes and alterations in intradiscal pressure after an experimental intradiscal injection in the mature rabbit. Thirty intervertebral discs in 6 rabbits were used as controls, and normal pressures were measured. Chymopapain, 10% sodium chloride, or betamethasone were injected separately into 5 intervertebral discs of 9 rabbits. Rabbits were sacrificed at 1 week, 4 weeks, and at 12 weeks after the intradiscal drug injection. The intradiscal pressure changed depending on the degree of disc degeneration and if there was any regeneration. The chymopapain-injected intradiscal pressure decreased significantly at 4 weeks compared with the pressure at 1 week and at 12 weeks (p
