IntroductionIn the present research, we formulated a modern chemotherapeutic drug by silver nanoparticles ‎‎(AgNPs) containing Matricaria chamomilla aqueous extract for the treatment of oral squamous ‎cell carcinoma.Material and methodsCharacterization of AgNPs was done by UV–Visible Spectroscopy (UV-Vis), Fourier ‎Transformed Infrared Spectroscopy (FT‐IR), Transmission Electron Microscopy (TEM), and ‎Field Emission Scanning Electron Microscopy (FE‐SEM). For investigating the antioxidant ‎properties of AgNO3, M. chamomilla, and AgNPs, the DPPH test was used in the presence of ‎butylated hydroxytoluene as the positive control. To survey the cytotoxicity and anti-oral ‎squamous cell carcinoma effects of AgNO3, M. chamomilla, and AgNPs, MTT assay was used ‎on the HSC-4, Ca9-22, and HSC-3 cell lines. ‎ResultsDPPH test revealed similar antioxidant potentials for M. chamomilla‎, AgNPs, and butylated ‎hydroxytoluene. Silver nanoparticles had very low cell viability and anti-oral squamous cell ‎carcinoma properties dose-dependently against HSC-4, Ca9-22, and HSC-3 cell lines without ‎any cytotoxicity on the normal cell line. The best result of anti-oral squamous cell carcinoma ‎properties of AgNPs against the above cell lines was seen in the case of the HSC-3 cell line. ‎ConclusionsAccording to the above findings, the silver nanoparticles containing M. chamomilla aqueous ‎extract can be administrated in humans for the treatment of several types of oral squamous cell ‎carcinoma. ‎

Abstract Background: Former clinical trials and experimental research have indicated that interferon-gamma (IFNγ) therapy does not achieve an ideal effect in solid tumors. Autophagy has been associated with tumor chemoresistance. The aim of this study was to explore the efficacy of IFNγ and autophagy inhibitor in the combination treatment of oral squamous cell carcinoma (OSCC). Method: IFNγ-induced apoptosis was evaluated by the expression of relative proteins (cleaved-PARP and caspase-3) and flow cytometry. IFNγ-induced autophagy was assessed by the expression of Beclin1, LC3B, and P62. The synergistic effect of IFNγ and autophagy inhibitor (chloroquine) was evaluated in vitro and in vivo.Findings: IFNγ induced anti-proliferation, apoptosis, and autophagy in OSCC cells. Autophagy-related protein 5 (ATG5) was a key feature in IFNγ-induced autophagy flux. IFNγ and chloroquine had obvious synergistic effects on cellular growth inhibition and apoptosis promotion in OSCC cells and xenograft models. Interpretation: Our findings suggest that IFNγ-induced autophagy plays a cellular protective role, and blocking autophagy flux can promote IFNγ-mediated OSCC cell apoptosis. The combination of IFNγ and autophagy inhibitors represents a novel strategy for OSCC therapy.

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.
