Influence of T-actemodulin on herpes simplex virus infection.

The aim of the investigation was to study the direct influence of T-actemodulin (TAM) on the Herpes Simplex Virus (HSV) infection in vitro and in vivo. HSV-1 (strain Vic) and HSV-2 (strain Nissa) were used in the experiments in vitro. The experiments were performed using multicycle and singlecycle growth tests. Seventy-five patients suffering from HSV infections (labialis and genitalis) were locally treated by 0.04% TAM-containing hydrophilic gel or water-washable cream (applied every 3 h). The results showed that TAM: decreased the infectious virus titre; reduced the infectious virus yield at the end of the single cycle of the virus replication; prolonged the latent period; and exerted an irreversible inhibitory effect on the infectious virus titre when applied at immediate early intervals after the infection. No relapses were observed in 84% of the patients treated with TAM. Eight percent of the patients were with only reduced relapses and in 8% of the patients TAM had a mild effect. TAM exerted a preventive effect against the disease when the treatment was initiated in the period of paresthesia.
