Our aim was to establish an effective non-surgical treatment for cervical intraepithelial neoplasia (CIN) through inactivation of human papillomavirus (HPV), the major etiological agent for this disease. We show that vidarabine, a DNA polymerase inhibitor, suppressed growth and HPV gene expression
Giant condyloma acuminatum (also known as Buschke-Löwenstein tumor) is a rare disease, for which the treatment of choice is still controversial. In the case described in this report, we used a combination of electrocautery and a surgical scalpel to resect a huge genital wart, followed by long-term
Histochemical activity of acid DNAse, intensity of nucleic acid staining and histological alterations in mouse interfollicular epidermis (I.F.E.) were investigated after a single dose or after chronic topical administration of two hyperplastic agents, of which one (croton oil) was a potent tumor
The study reported herein utilized the Agrobacterium tumefaciens-induced potato disc tumor assay. The objective was to verify the detection of antineoplastic activity in the potato disc tumor induction assay, regardless of the mode of antineoplastic drug action. Camptothecin, paclitaxel,
Allergic reactions of dramatic intensity were observed in 5 children treated with Teniposide (VM-26) for acute lymphoblastic leukaemia and histiocytosis X. In the further treatment this drug was replaced with epoxide, a cytostatic agent which is also a podophyllin derivative but in other chemical
The specific inhibition of eukaryote DNA topoisomerase II by the anti-cancer drugs VP16, VM26, and 21 other congeners of podophyllotoxin has been extensively studied in this laboratory through the use of alkaline elution and other techniques. A structure-activity relationship has been established
OBJECTIVE
Normal bone marrow cells have little or no expression of the MDR p-glycoprotein product and, therefore, are particularly susceptible to killing by MDR-sensitive drugs, such as vinca alkaloids, anthracyclines, podophyllins, and paclitaxel and its congeners. Here we report the results of a
The incidence of condylomata acuminata infection has shown a steady increase for adults and children in recent years. With the discovery that the viral agents of this disease are potentially neoplastic, a disorder that was once considered a nuisance is now taking on new-found importance and concern.
There are now known to be many genotypes of human papillomavirus (HPV). Types 6 and 11 are closely associated with benign lesions of genitoanal epithelia; the classical forms are condylomata acuminata and papular warts, collectively known as genitoanal or "venereal" warts, but it is now known that
Cervical dysplasia, a premalignant lesion that can progress to cervical cancer, is caused primarily by a sexually transmitted infection with an oncogenic strain of the human papillomavirus (HPV). The HPV infections are treated through destroying the clinical lesions: laser, cryotherapy,
The aqueous extract of Podophyllum hexandrum (RP-1), which has been recently reported to manifest radioprotective and anti-tumour properties, has been investigated for its mode of action. RP-1, under in-vitro conditions dose-dependently chelated metal ions, inhibited radiation or metal ion-induced
Etoposide (VP 16) is an antineoplastic agent that has major activity against a number of tumors, including germ cell neoplasms, small cell lung cancer, and malignant lymphoma. It is a derivative of podophyllin, and acts by inhibiting mitosis. Common side effects include bone marrow suppression,
BACKGROUND
Condyloma acuminatum are caused by human papillomavirus. Giant condyloma acuminatum is a locally invasive, destructive, and large sized mass. Risk factors for the development of giant condyloma acuminatum include an immunodeficient state, such as human immunodeficiency virus infection,
