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.
Background: Oral squamous cell carcinoma (OSCC) is the most common public health issue in Indian population. Quite a large number of OSCC cases are preceded by potentially malignant disorders of oral cavity. The need for simple diagnostic marker for early diagnosis and thus better therapeutic outcome is imperative. The current study aims to evaluate hematological parameters such as hemoglobin, bleeding time, clotting time, total leucocyte count (TLC) and differential leucocyte count (DLC) in OSCC and oral potentially malignant disorder cases along with normal healthy controls.Methods: A total of 150 subjects; 50 in each group were taken and 2.5 ml of blood were withdrawn from each subject and TLC, DLC and hemoglobin assessment was done using autoanalyzer while bleeding time and clotting time was recorded through Duke’s method and modified Dale’s method respectively.Results: All the data were tabulated and recorded as mean±standard deviation and comparison was done using one-way ANOVA test (p<0.05). TLC count, neutrophil count and lymphocyte count showed statistically significant difference amongst three groups while other parameters such as hemoglobin percentage, bleeding time, clotting time, eosinophil count, monocyte count and basophil count were statistically non-significant.Conclusions: This study showed TLC count, neutrophil count and lymphocyte count might prove as useful determinant factor in oral squamous cell carcinoma and oral potentially malignant disorders. However, further study with larger sample size is required to establish their role as diagnostic, prognostic marker or predictor of malignant transformation.
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.
Oral cancer accounts for 2-4% of diagnosed cancers, annually in the United States. Oral cancer is a common neoplasm in Asia and the Pacific Islands, particularly in India. It is believed that oral mucosal carcinomas are predominantly caused by chemical carcinogens, although viral, fungal, and physical stimuli in the genesis of some oral neoplasms are also implicated. Curcumin, (diferuloyl methane), a hydrophobic polyphenol derived from the dietary spice turmeric, is a free radical scavenger and hydrogen donor, that exhibits both pro-and antioxidant activities. It binds metals, particularly iron and copper, and is an iron chelator. Curcumin is remarkably a non-toxic substance and exhibits limited bioavailability. In the plethora of phytochemicals derived from dietary components, natural substances traditionally used in ancient medicines for their anti-inflammatory and antioxidant actions, curcumin is studied in order to combat human diseases, especially in cancer. It has antioxidant and anti-inflammatory properties and appears able to reduce the risk of cancer. The reported activity of curcumin against leukemia and lymphoma, gastrointestinal cancers, genitourinary cancers, breast cancer, ovarian cancer, head and neck squamous cell carcinoma, lung cancer, melanoma, neurological cancers, sarcoma and oral cancer, reflects its ability to affect multiple targets in a nonlinear manner. The present review summarizes the most recent advances in the field, providing also new insights into the molecular mechanisms underlying the promising anticarcinogenic activity of the dietary polyphenol curcumin.
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.
