Chalkley counting has been regarded as a relatively reliable method of quantifying tumor angiogenesis. In this study we investigated the reliability of Chalkley counting in quantifying tumor angiogenesis in oral tongue squamous cell carcinoma (OTSCC) using CD34; and tumor vasculogenesis using angiotensin converting enzyme, angiotensin II receptor 1 and angiotensin II receptor 2, in 32 OTSCC samples. Chalkley counting was performed by two independent observers. The averages of three ‘hot spot’ counts were compared with known prognostic factors. All four markers showed no correlation with any of the prognostic factors. When comparing the results from the two independent observers, the only marker shown to have a significant moderate correlation was CD34. The other three markers showed no significant correlation. The lack of statistical significance between the independent observers, and known prognostic factors with the four markers used, shows that Chalkley counting is not a reliable prognostic tool in OTSCC.

Earlier studies reported significant association of obesity, hypertension and Type2 Diabetes Mellitus (T2DM). Genetic and many disease-associated alleles have been identified through GWAS and applied to T2DM and indicated roles of renin-angiotensin system (RAS) in insulin signaling pathway and insulin resistance has been well documented. Angiotensin converting enzyme (ACE) gene catalyzes the conversion of angiotensin I to angiotensin II and also inactive the vasodilatation and hence renin-angiotensin system (RAS) in insulin signaling pathway and insulin resistance has been reported. To best of the knowledge we are reporting for the first time regarding association of ACE gene polymorphism with body composition, physiological and metabolic variables among any endogamous ethnic group (Kurmis) from of West Bengal, Eastern India. To achieve the purpose, total 197 (male 99 and female 98) randomly selected apparently healthy unrelated adult individuals of Kurmi population of Purulia District, West Bengal, India were incorporated in the present study. Anthropometric variables, physiological variables (blood pressure) and metabolic variables (PP blood sugar) have been collected using standard techniques. Extracted genomic DNA was PCR amplified and genotyped to understand ACE gene I/D polymorphism. The result demonstrated significant (p<0.05) sexual dimorphism in PBF. MAP and PP blood sugar found to be in normal range among the Kurmis. ACE gene polymorphism showed no deletion of the Kurmis and hence, only the prevalence of ACE II (insertion-Insertion) genotype has been noticed. The present study vindicated on the basis of body composition in terms of fat patterning, physiological and metabolic variables and ACE gene polymorphism that there is very low or no risk of T2DM among the Kurmis of West Bengal, India.
