RESUMO
A study evaluating the therapeutic effect of recombinant interferon-a ointment on several viral skin diseases was done. A total of 204 patients, 92 of herpes simplex, 90 of herpes zoster and 22 of varicella, were included in this study. Two different concentration of recombinant interferon-a ointment(l*10IU/g; group A, 1*10IU/g; group B) and placebo vehicle(control group) were applied topically on the early lesion of the disease. The evaluation of therapeutic effect was done by the measurement of time interval from the day of vesicle formation to the day of crust formation, The results were as follows; 1. Herpes sirnplex: Crust formation observed within 6 days in 70. 1% of group A. 63.9% of group B and 26.7%, of control group. The time of crust formation of group A and B was shorter than that of control group (p<0.01, P<0.05). 2. Herpes zoster: Crust formation observed within 10 days in 64. 3% of group A. 46.7% of group B and 33. 3% of control group. The time of crust formation of group A was shorter than that of control group (p<0.05). 3. Varicella: Crust formation observed within 6 days in 87. 5% of group A, 72.7% of group B and 66.7% of control group. Therefore we have been impressed that recombinant interferon-a ointment is an effective topical therapeutic agent and 1*10IU/g recombinant interferon-a clintment is more effective than 1*10IU/g recombioant interferon-a ointment for above viral skin diseases.
