BIOCHEMICAL & ANTIOXIDANT PROPERTIES OF WILD EDIBLE MUSHROOMS USED FOR FOOD BY TRIBAL OF EASTERN INDIA
Objective: The main objective of this research was to analyze some selected indigenous wild edible mushrooms in Eastern India for their novel antioxidant components and their properties specifically used by primitive tribal groups of Eastern India.Methods: The antioxidant components were analyzed by standardized spectrophotometric methods. The antioxidant properties were analyzed by DPPH Free radical scavenging & Reducing power ability assay.Results: The TPC (phenolic content) in the studied edible mushroom varied from 4.55 mg/g (Russula nigricans) to 0.9 mg/g GAE (Lentinus tuberigium). Measured in term of antioxidants Termitomyces group ranked higher than Russula and Volvariella sp. The scavenging effect of studied mushrooms on 1,1 DPPH varied from 61% to as high as 94%. On the other hand, reducing power (RPA) in methanolic extracts were in the order of T. clypeatus (4.21) T. heimi (2.20) ~R. breviceps (1.73) ~ Termitomyces eurrhizus (1.11) ~ T. rufum (1.07). Antioxidant potential inedible wild mushrooms are found to be on account of combinations of biochemicals, rather than any such significant individual components as TPC, AA, or alkaloid. Conclusion: This is for the first time wild edibles such as Termitomyces clypeatus, Termitomyces eurrhizus, Termitomyces heimii, Russula brevipes, Tuber rufum, Russula nigricans, Volvariella volvaceae, Lentinus fusipes, Lentinus tuberigium and R. lepida from eastern India were observed, collected and subjected to nutritional and biochemical analysis. Of significance is the identification of Tuber rufum and Volvariella volvaceae growing wild as edible mushrooms which have not been profiled in the Indian context. The analysed mushroom especially Lentinus fusipes and Lentinus tuberigium was found valuable in terms of iron and calcium, besides having useful phytochemicals such as phenolics, ascorbic acid, carotenoids.

Prevalence, risk factors and health seeking behaviour of pulmonary tuberculosis in four tribal dominated districts of Odisha: Comparison with studies in other regions of India.
AIM:To determine the prevalence of pulmonary tuberculosis, socio-cultural practices and health seeking behaviour of tribal people in four districts of Odisha. METHODOLOGY:This was an action research study with qualitative and quantitative design following a sequential approach implemented in a 4-phased manner. It was carried out in the 6 selected villages from July,2015 to June,2017. The screening for active TB among chest symptomatics is followed as per the guidelines of the (RNTCP) Revised National Tuberculosis Control Program in India. RESULTS:In all, 1455 households were surveyed in the 6 tribal dominated villages of 4 districts, namely Balangir, Dhenkanal, Kandhamal and Mayurbhanj. Total population of the villages was 6681. Based on the eligibility, 5144 (97.7%) individuals were screened. About 139 (2.3%) could not be screened due to non-availability in their households during day time. Out of the screened individuals (5144), 126 chest symptomatics were identified. Sputum samples were collected from them and sent to the National Reference Laboratory, RMRC, Bhubaneswar using public transport and maintaining cold chain. Out of 126 chest symptomatics, 35 patients were found to be having active TB disease and 18 were culture positive. The prevalence of pulmonary TB is 0.68%. The risk factors seemed to be ignorance about TB symptoms, addiction to alcoholic drinks, difficulty reaching the health facilities owing to the long distances, lack of communication and transport. In addition, other morbidities like Malaria, diabetes, hypertension, malnutrition, etc. were observed in the tribes of the study sites. CONCLUSION:TB control programs need further strengthening in the tribal dominated regions. This study is the first of its kind in this State
