    Objective: In the current study we have stimulated the efficacy of plasmonic nanoparticles (NPs) by laser hyperthermia to achieve a less invasive method for tumor photothermal therapy of benign prostatic hyperplasia (BPH). Methods: The levels of apoptosis on induced BPH in rats were assessed after treatment and revealed and recorded by various assayed. Moreover, the expression of caspases was considered to demonstrate the apoptotic pathways due to laser induced plasmonic NPs. Results: In the Laser + NPs group prostate size of induced BPH decreased. Laser + NPs also decreased prostate specific antigen in comparison with the BPH groups. Furthermore, Laser + NPs attenuated BPH histopathologic indices in the rats. Laser + NPs induced apoptosis in prostatic epithelial cells via caspase-1 pathway. Conclusions: Altogether, the approach and findings from this study can be applied to introduce the laser irritated NPs method as a novel and less invasive therapy for patients suffering from BP

    OBJECTIVES: Several studies have attempted to prevent or improve oral mucositis (OM) but have not produced a qualified treatment yet. This study evaluates the effects of Carum carvi L. (caraway) hydroalcoholic extract (CHE) as one of the traditional medicinal plants in 5-flurouracile (5-FU) induced OM in golden hamsters. MATERIALS AND METHODS: OM was induced in 54 male golden hamsters by 5-FU and cheek pouch scratching. Starting from day 12, 500 and 1000 mg/kg/day dietary CHE were administered. Pouch histopathology score, malondialdehyde and reduced glutathione contents, and activity of myeloperoxidase plus microbial cultures of cheek pouch, antimicrobial properties of CHE, and essential oil constituents were evaluated. RESULTS: Lower histopathology score (0, 1, and 2) and malondialdehyde level, higher reduced glutathione level and activities of myeloperoxidase were detected in 1000 and 500 mg/kg/day dietary CHE and control groups, respectively (P<0.001). The CHE was more potent against Staphylococcus epidermidis and Streptococcus intermedius. γ-terpinene (37.2%) was identified as the main constituent of essential oil. CONCLUSION: The use of CHE in dietary form may be associated with reduced intensity of OM. This may be due to appropriate antibacterial activity and terpinene contents.
