Management of Vatarakta (Gouty Arthritis) in Ayurveda - A Review

Vatarakta is a Vatapradhana Tridoshaja Vyadhi where Raakt is main Dushya. It is described under Vatavyadhi Chikitsa in Sushruta while Charaka has emphasised it in a separate chapter for Vatarakta after Vatavyadhi Chikitsa. It is a chronic and complex metabolic disorder of musculoskeletal system and characterised by severe pain, tenderness, inflammation and burning sensation in the affected joints. Vatarakta is an illness where in both Vata and Rakta are afflicted by distinct causative factors. The etiology, pathology and clinical features of Gouty Arthritis are quite similar to that of Vatarakta. Rapid modernization, Junk food culture, stressful life and urbanisation are the markers for prevalence of Vatarakta. Due to excruciating pain, inflammation, joint deformity and restricted joint movements with the risk of various complications like Chronic Kidney Disease and Urate Nephrolithiasis, it is necessary to have an overall review on all aspects of disease for treatment. Because of the morbidity, chronicity, incurability and complications, the management of Vatarakta is a difficult task. Hence an attempt has been made to focus on Shamana Aushadis and Shodhana procedures recommended in different authentic texts of Ayurveda. Evaluation of efficacy and framing certain guideline protocols for the budding Pharmaceutical and Clinical Researchers as a readymade reckoner are the main aim and objectives of this review

Kinetics of oxidation of toluidine blue by periodate: Catalysis by water pools of CTAB

Kinetic study of oxidation of toluidine blue (TB+) by periodate was carried out in aqueous medium and also in the cetyl trimethyl ammonium bromide (CTAB) reverse micellar medium. In both the media reaction obeys first order kinetics with respect to each of the reactants. In the reverse micellar medium, the reaction is forty times faster compared to aqueous medium under identical experimental conditions. The pronounced acceleration is accounted for by the lower micro polarity and the concentration effect present in the bound water of reverse micelles. In CTAB reverse micellar medium, the pseudo first order rate constant (k’) of the reaction is almost constant at all values of W, {W=[H2O]/[CTAB]} indicating that the reaction takes place on the micellar surface and results were explained by modified Berezin pseudo phase model.

Web enabled Decision Support System (DSS)In each crop there exists huge yield variation (farmers’ average yield) between districts in the country. A part of this variation can be explained by various climatic and edaphic factors in combination with irrigated area under the crop and season (kharif/rabi) in which it is grown. It is quite possible that within a cluster of districts (not necessarily be contiguous) with similar climatic and edaphic factors and share of irrigated area and share of a particular season in area under the crop, significant variation exists between districts with respect yield of a crop. Yield of a district that tops in a cluster may be regarded as potential yield for the remaining districts in the cluster and the yield gaps for the districts in the cluster may be estimated as lag from the potential yield. Major districts were identified for each crop with criteria like area sown to the crop is more than 10,000 ha. In case of rice, a district with more than 20,000 ha area is considered as major district. The technique of multivariate cluster analysis was used for clustering major districts of each crop. The clustering variables used were climate, available water holding capacity of soil and per cent irrigated area under the crop. Climate was assessed by moisture index computed from rainfall and potential evapo-transpiration data for the years 1971-2005 [Raju et. al., 2013, Current Science, 105(4): 492-495]. Edaphic factors like soil texture and soil depth were summarized by computing available water holding capacity of soil [Raju et. al., 2015, Journal of the Indian Society of Agricultural Statistics, 69(1): 83-93]. In case of crops viz., rice, sorghum and maize share of rabi season area was used as 4th clustering variable. Share of kharif season area was considered as 4th clustering variable in case of blackgram and greengram crops. Study of variation in yield between districts within a cluster vis-à-vis crop management practices adopted in those districts may be found useful in targeting the yield gaps in districts having relatively low productivity despite similar resources. The variation in crop management such as consumption of nutrients like Nitrogen (N), Phosphorous (P) and Potassium (K) and extent of use of High Yielding Varieties (HYV), etc. explained between district variation in yield within a cluster to a large extent. The yield gaps in the districts having relatively low productivity within a cluster may be attempted to bridge with a consideration of economic feasibility. A decision support system (DSS) has been developed based on the work carried out. The DSS accommodates 17 rainfed crops viz., rice, sorghum, pearlmillet, maize, fingermillet, chickpea, pigeonpea, blackgram, greengram, lentil, groundnut, soybean, sunflower, sesame, rapesedd & mustard, castor and cotton. User has to select a crop and a district cultivating the crop. The DSS provides climate and available water holding capacity (AWHC) of soil of the district and share of irrigated area and share of a particular season (in case of rice, sorghum, maize, blackgram and greengram) in area under the crop and yield of the district in the crop. The DSS identifies 3 model districts having climate, soil, share of irrigated area under the crop and share of a particular season (in case of rice, sorghum, maize, blackgram and greengram) in area under the crop similar to the district (target) selected. It further provides yield achieved by model districts. If the target district itself is the highest yielding district in the cluster, a remark to this effect is generated. If there are only 1 or 2 districts with yield more than that of target district in a cluster, only those districts will be listed as model districts. The highest yield among the model districts may be regarded potential yield. The difference between potential yield and yield of target district is regarded as unreaped yield potential. The DSS gives unreaped yield potential and its % to potential yield and nutrient use in terms of N, P, and K and extent of adoption of HYVs in target district. Nutrient use in terms of N, P, and K and extent of adoption of HYVs were furnished for model districts also to explore scope for bridging the yield gap in those lines.Not Availabl
