    Abstract:
    INTRODUCTION: Primary herpes simplex virus (HSV) infections of female genital tract usually end with remission, while the virus remains in the organism--almost in the sacral ganglion in a latent form, protected from humoral and cellular immunity. Stress induces the virus and the result is recurrent genital infection. Frequent exacerbations damage some parts of vital cellular structures without cytolysis, but stimulate malignant transformations. MATERIAL AND METHODS: Vulvar (portio vaginalis uteri) and endometrial tumor tissue samples were analyzed for HSV by direct and indirect fluorescent antibody technique (FAT). Pre and postoperative sera samples were analyzed for presence of anti-HSV antibodies--IgM and IgG by Elisa-Enzygnost method. Acellular filtrates obtained by ultrasonic destruction of malignant tissues were used as inoculum for rabbit corneal scarification. RESULTS AND DISCUSSION: Out of 63 tissue samples, 42 were positive for HSV antigen i.e. 67.3%. According to location 50% of vulvar, 76% PVU and 65% of endometrial tissues were positive. This antigen induces production of virus specific antibodies. Two types of antigens are known: the so-called T-antigen persisting in the cell nucleus and cell-surface antigen--product of the viral genome and can be evidenced by immunofluorescence method. Anti HSV antibodies were present in 63 preoperative serum samples and belonged to IgG group, but not one to IgM, implying a long and chronic course of infection excluding acute primary. Out of 38 postoperative serums the titer of antibodies decreased in 36 evidently, but in two samples remained unchanged. Two samples of endometrial and one from PVU origin contained HSV antigen type one. In the remaining 16 samples HSV 2 antigen was present. Rabbit corneal scarification was the proof of complete infectious virus in malignant tissues. Acellular filtrate of malignant tissues served as inoculum. Corneas of examined rabbits showed a mild inflammation after 24 hours which disappeared in the next 24 hours. We could not isolate the infectious virus by rabbit corneal scarification. Instead of herpetic changes, mild inflammation was evident. This abortive, incomplete symptomatology was probably caused by nonstructural early protein, which is a product of viral genome incorporated in malignant cells. CONCLUSION: On the basis of our results, we can conclude that HSV can have, beside other factors, a very important, maybe an initial role in development of malignant changes of female genital tract, not only on vulva and PVU, but on endometrium as well. HSV I can cause genital infections and have some role in malignant changes as well as HSV 2. However, complete infective virion couldn't be isolated from malignant tissues.
