The study of antiviral activity of 7 samples of liquid corneal storage medium on a model of herpesvirus infection caused by the herpes simplex virus type 1 in Vero-cell using virological and statistical research methods was carried out. All the studied images of the corneal storage medium, including the Borzenka-Moroz base medium, did not have a cytotoxic effect on Vero cell culture. Out of of 7 samples of liquid corneal storage medium, 4 samples had reliable antiviral activity against HSV-1 when used under the therapeutic regimen (1 hour after infection) and under the preventive regimen (2 hours before infection). Antiviral activity was established in 2 samples containing the interferon inducer cycloferon at a concentration of 10 mg/kg and 30 mg/kg (sample 2, 3), in a sample containing the interferon inducer gamapren 15 mg/kg (sample 5), and in a sample containing a combination of drugs - 10 mg/kg cycloferon and an acyclic nucleoside analog-acyclovir 10 mg/kg (sample 6). According to the results of 2 test regimens, the maximum statistically significant inhibitory effect in relation to HSV-1 was detected in sample 6, containing a combination of drugs. Against the background of sample 6, the infectious activity of the test virus decreased by an average of 3.2 lg, the inhibition coefficient was 54.5%. The results of the study indicate the prospects of using types of media with antiviral activity (samples 2, 3, 5, 6) for storing donor corneas in order to increase the effectiveness of keratoplasty in patients with ophthalmic herpes.
