ABSTRACT
BACKGROUND AND AIMS: Inflammation is considered to be the seventh hallmark of cancer and plays a pivotal role in all stages of tumor development. Systemic inflammatory responses in particular neutrophil to lymphocyte ratio (NLR) have garnered immense attention of current researchers and its role is well proven in various solid malignancies. Its prognostic role in oral cancer have been extensively studied. However, its diagnostic role is yet to be explored. The current study aims to investigate diagnostic utility of NLR in oral potentially malignant disorders and oral cancer, when compared to normal subjects. METHODS: A total of 150 subjects were involved in the study, a total of 2.5 ml of blood was drawn from the median cubital vein of the patient in an EDTA vial and hematological parameters were assessed using Erba-Transasia B7256 Autoanalyzer and reassessed manually by two experts. STATISTICAL ANALYSIS: The NLR values were recorded and tabulated as Mean ± S.D. and comparisons were analyzed using Kruskal Wallis and Mann Whitney post hoc U test. ROC curve analysis was performed to estimate cut-off values. RESULTS: The NLR values when compared between the 3 groups were statistically significant (P < 0.001). The cut off value between disease and normal subject was 2.33, while the cut-off value between potentially malignant and malignant condition is 3.20. CONCLUSION: NLR can be a valuable diagnostic adjunct in oral cancer and potentially malignant disorders of oral cavity.

INTRODUCTION: Telomerase is a ribonucleoprotein complex responsible for de novo telomere synthesis and addition of telomeric repeats to existing telomeres. Telomerase activity is generally found to be absent in normal tissues. Telomerase is known to be induced upon malignant transformation of human cells. METHOD: In the present study, we analyzed both telomere length and telomerase activity in saliva samples from oral carcinoma patients. The study was done to investigate the presence of telomerase activity in oral squamous cell carcinoma by TRAP assay. RESULT: Telomerase activity was detectable in 79 of 100 human OSCC and 51 of 100 premalignant cases and 8 of 100 normal patients. CONCLUSION: These results indicate that telomerase is activated frequently during the late stage of oral premalignancy and may play a crucial role in OSCC.
ABSTRACT
Candida carriage was reported to be common in oral cancer patients, with C. albicans being the predominant species. The prevalence of diseases caused by Candida species have been found to increase in recent years. AIM: The aim of our study was to find the antifungal activities at MIC of selected fifteen plant leaves extracts prepared in three different solutions (methanol and ethanol) against the opportunistic pathogen Candida albicans isolated from oral cavity infections. It may also help the clinician to treat the patient not only for the particular lesion that is present, but also to treat the infection by Candida albicans so as to reduce its potential to malignant transformation. Material n methods: Leaves extract of selected plant prepared in methanolic and eethanolic solution have been chosen for the investigation of in vitro antifungal activity which acts as expectorant and not having toxic properties on humans while for comparison or control, antifungal drugs have been taken. Results showed that Candida albicans shows most sensitivity towards the standard antibiotic cotrimoazol but very less towards other drugs like Fluconazole, minocycline, erythromycin respectively which indicated Candida albicans shows some resistance character towards drugs while the herbal extracts of Lawsonia inermis, Withania somnifer, Curcuma longa, Cymbopogon citrates and Zingiber officinale gives the best inhibitory effect and they have the potential to control growth of Candida albicans.
