AIMS To determine whether a new, reversible thermosetting gel enhances mitomycin C transfer to target ocular tissues in the rabbit eye. METHODS A 0.1 ml solution of mitomycin C containing 0.22 microgram, 2.9 micrograms, or 28 micrograms of the agent dissolved in a reversible thermosetting gel consisting of methylcellulose, citric acid, and polyethylene glycol was injected subconjunctivally in...

PURPOSE We compare the therapeutic efficacy and toxicity of intravesical bacillus Calmette-Guerin (BCG) with mitomycin C on recurrence of stages Ta and T1 bladder carcinoma. MATERIALS AND METHODS Combined published and unpublished data from comparative studies on BCG versus mitomycin C for superficial bladder carcinoma considering possible confounding factors were analyzed. Odds ratio (OR) an...

The dimethyl sulfoxide induced erythropoietic differentiation of murine erythroleukemia cells, as determined by scoring benzidine positive cells, is inhibited by mitomycin C at concentrations that have no effect on cell proliferation. The inhibition occurs only when cells are treated with mitomycin C during induction and has a limit value of about 50%, independent of mitomycin C concentration. ...

PURPOSE To investigate whether mitochondrial dysfunction and mitogen-activated protein kinase family proteins are implicated in apoptotic signaling of human Tenon's capsule fibroblasts (HTCFs) by mitomycin-C. METHODS Apoptosis was determined by Hoechst nuclei staining, agarose gel electrophoresis, and flow cytometry in HTCFs treated with 0.4 mg/mL mitomycin-C for 5 minutes. Enzymatic digestio...

OBJECTIVE Topical application of mitomycin C appears to be a useful adjunct in reducing cicatricial scarring of the airways. Human and animal studies have demonstrated the efficacy and safety of mitomycin C topically in the treatment of airway stenosis at concentrations ranging from 0.4 mg/mL to 10 mg/mL. Although no reports of mitomycin C toxicity have been reported in the otolaryngology liter...
