简要总结
ZnO nanoparticles are now being widely researched for their anticancer properties. They show relatively high biocompatibility. They also show selective cytotoxicity against cancerous cells in in vitro condition compared with other nanoparticles. They can be further surface engineered to show increased selective cytotoxicity. The synthesis process of ZnO nanoparticles is relatively easy, with a wide variety of methods. Owing to these different methods of synthesis, their size and size distribution can be easily controlled. One of the novel methods of synthesis of ZnO is Magnetite ZnO-Fe3O4 Composite Nanoparticles.Magnetite ZnO-Fe3O4 conjugated NPs retained inherent selective property of ZnO and magnetic property of Fe3O4 NPs and showed preferential cytotoxicity towards breast cancer cell line MDA-MB-231, with no significant cytotoxicity towards noncancerous Mouse Fibroblast NIH 3T3 cell.
详细描述
Two interventions will be used; Magnetite ZnO-Fe3O4 Composite NPs extract and Placebo gel in custom made inert hydrophilic adhesive gel paste will be prepared in Nanotechnology engineering service in Egypt (Nano Gate), to enhance the adhesiveness of the two study interventions to oral mucosa.Group I (Test Group): Will include 15 patients with OPLs that will be treated with 5% topical ZnO-Fe3O4 Magnetic Composite NPs gel applied 3 times per day33 for 6 weeks9.
Group II (Positive Control Group):
Will include 15 patients with oral lichen planus lesions that will be treated with Topical Placebo Gel applied 3 times per day for 6 weeks.
The whole study period will be 18 weeks; 6 weeks as an active treatment period starting 1 week after the biopsy is taken then treatment discontinued for all groups and patients will be followed up for another 12 weeks in a treatment-free period.IV-Treatment efficacy evaluation A) Clinical efficacy assessment The assessment will be carried out at 0, 6 weeks and 18 weeks after starting the treatment protocol.
1-Imaging of the oral marker lesion Standardized photographs of the oral marker lesion for each patient will be taken with the same digital camera and setting, the surface area of the lesion will be outlined and measured using specific image software.

- •Histopathological confirmed OPMLs with low or moderate dysplasia
排除标准
- •Presence of systemic conditions as serious active or recurrent infections, malignancy, diabetes mellitus, hypertension, or significant heart, liver, or renal diseases. Assessed using a medical questionnaire guided by Cornell Medical Index
