Diffusion of Cortexin and Retinalamin in eye sclera
2007
ABSTRACT Spectral measurements of sclera reflectance during its interaction with aqueous solutions of both Cortexin and Retinalamin have been carried out. Twenty three samples includ ed in the study were human sclera and rabbit sclera in vitro . The results of the experiments have shown that penetration of Cortexin as well as Retinalamin into sclera tissue leads to the decrease of sclera reflection due to optical immersion. Estimation of diffusion coefficients of studied solutions was made on the basis of analys is of reflectance change dynamics of the sclera samples. Diff usion coefficients of Cortexin and Retinalamin in sclera tissue were estimated as 4.4 2.7 10ru 6 and 1.82 0.14 10ru 6 cm 2 /sec, respectively. Obtained values of diffusion coefficient allowed estimating time needed for total penetr ation of both agents through scleral membrane at subtenon's injection of studied agents. The results are important for treatment of partial optic atrophy observed at primary open-a ngle glaucoma and others eye diseases.
