Introduction: Silymarin is obtained from Silybum marianum (milk thistle), an edible plant that has long been used medicinally for the treatment of liver-related disorders. Silymarin is a powerful hepatoprotective and antioxidant but the anticlastogenic activity, which is an important aspect of its cancer chemoprevention is not known hence the present investigation was carried out to study its...

The effects of 7-N-(p-hydroxyphenyl)mitomycin C (M-83), a derivative of mitomycin C, against eight human tumor xenografts serially transplanted into male BALB/c nude mice were evaluated. M-83 showed positive antitumor effect against six out of eight tumor strains. The antitumor spectrum of this agent was similar to that of mitomycin C except for two strains. The serum level of M-83 detected by ...

Solid neoplasms may contain deficient or poorly functional vascular beds, a property that leads to the formation of hypoxic tumor cells, which form a therapeutically resistant cell population within the tumor that is difficult to eradicate by ionizing irradiation and most existing chemotherapeutic agents. As an approach to the therapeutic attack of hypoxic cells, we have measured the cytotoxici...

NADH:cytochrome b5 reductase activates the mitomycins to alkylating intermediates in vitro. To investigate the intracellular role of this enzyme in mitomycin bioactivation, Chinese hamster ovary cell transfectants overexpressing rat NADH:cytochrome b5 reductase were generated. An NADH:cytochrome b5 reductase-transfected clone expressed 9-fold more enzyme than did parental cells; the levels of o...

Objective: To determine the effect of intravitreally administered bevacizumab, alone or as adjunct to mitomycin-C, after trabeculectomy on bleb survival and histology in rabbit eyes. Methods: An experimental, interventional, comparative, animal study consisting of 16 rabbit eyes underwent trabeculectomy, 8 of which were enhanced with intra-operative mitomycin-C. Eyes were randomized to receive ...

Background: Surgical cytoreduction and simultaneous hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) is a common treatment for peritoneal carcinomatosis. During chemotherapy, mitomycin C frequently used. Mitomycin known to be nephrotoxic. Little about the effect of systemically absorbed on renal function during HIPEC surgery. Methods: In twenty-two patients undergoing cytoreduct...
