Biochemical effects of viscoelastic materials on the glycosaminoglycans in the organ-cultured rabbit trabecular meshwork.
We studied the effects of viscoelastic materials on the glycosaminoglycan (GAG) profiles in the organ-cultured rabbit trabecular meshwork (TM). The cultured specimens were divided into 4 groups: (1) control group; (2) 1% sodium hyaluronate-(Na-HA)-treated group; (3) 3% chondroitin-6-sulfate (CD6S)-treated group, and (4) 1% methylcellulose (MC)-treated group. They were cultured for 2 weeks and subjected to sequential enzymatic degradation. In the 1% Na-HA-treated group, the proportion of hyaluronic acid was significantly increased compared with the control group. In the 3% CD6S-treated group, the proportion of chondroitin sulfate was significantly increased compared with the control group. In the 1% MC-treated group, the GAG profile did not differ from the control profile.
