We measured mitomycin C (MMC) concentrations in ocular tissues in rabbits with variable dose (0.1, 0.2, or 0.4 mg) and duration of application time (1, 3, or 5 minutes) of MMC using high-performance liquid chromatography. Mitomycin C concentrations at the administered site after single subconjunctival application of MMC and after irrigation showed significant correlation with dose and duration ...

of Purpose: A comparison of long term effect on IOP and complications trabeculectomies performed with the adjunct of either postoperative 5 fluorouracil(5FU) or peroperative mitomycin C(MMC) in 100 cases of high risk glaucoma. &&&We prospectwly studied 52 eyes of46 patients treated with MMC (Follow up 15i8.7111) and compared it with a retrospective scrie of48 eyes 01 35 patients treated with 5F...

PURPOSE To study the aqueous and corneal pharmacokinetics of mitomycin C (MMC) after single topical administration to the central cornea and to evaluate the effects of different concentrations and different application times on the aqueous concentration of MMC. METHODS Mechanical epithelium debridement of the central 7.5 mm of the cornea was performed in New Zealand white rabbits, and a spong...

PURPOSE To evaluate the benefit of titrating the concentration and exposure time of mitomycin C (MMC) as an adjunct to trabeculectomy. METHODS This report consists of a retrospective study and a review of the literature. In the study, consecutive glaucoma patients were evaluated who underwent trabeculectomy with adjunctive MMC that was titrated for concentration and exposure time, based on pa...

PURPOSE To determine whether application of the anti-proliferation agent, mitomycin C (MMC), to the osteotomy site during dacryocystorhinostomy (DCR) surgery increases surgical success rates. METHOD We conducted a comprehensive meta-analysis of randomised controlled clinical studies relating to the adjunctive use of MMC in primary and revision, as well as external (EX-DCR) and endonasal DCR (...

OBJECTIVE Mitomycin C (MMc) is an antibiotic that exerts a potent antiproliferative effect in tumor cells. Because the proliferation of vascular smooth muscle cells (VSMCs) plays a prominent role in the development of restenosis after percutaneous coronary interventions, the present study examined the effect of MMc on VSMC proliferation and on neointima formation after arterial balloon injury. ...

Mitomycin c (MMC), a quinone-containing anticancer drug, is known to redox cycle and generate reactive oxygen species. A key enzyme mediating MMC redox cycling is cytochrome P450 reductase, a microsomal NADPH-dependent flavoenzyme. In the present studies, Chinese hamster ovary (CHO) cells overexpressing this enzyme (CHO-OR cells) and corresponding control cells (CHO-WT cells) were used to inves...

The S1 state dynamics of methoxy methylcinnamate (MMC) has been investigated under supersonic jet-cooled conditions. The vibrationally resolved S1-S0 absorption spectrum was recorded by laser induced fluorescence and mass-resolved resonant two-photon ionization spectroscopy and separated into conformers by UV-UV hole-burning (UV-UV HB) spectroscopy. The S1 lifetime measurements revealed differe...

background: lymphocytes of fanconi anemia (fa) show an increased sensitivity to the alkylating agents such as mitomycin c (mmc), but their responses to gamma-irradiation is controversial. the extent of dna damage in leukocytes of fa patients following irradiation and mmc treatment was studied at cellular and single chromosome level. methods: dna damage induced by gamma-rays and mmc was measured...

purpose : although applying mitomycin c (mmc) during photorefractive keratectomy (prk) has shown to reduce postoperative corneal haze but there is considerable evidence of mmc toxicity in the literature and concerns exist regarding side effects and long-term complications. we conducted this study to compare the efficacy of mmc 0.02% and 0.01% in prevention of haze after prk. methods : 210 eyes ...
