SYNERGISTIC IMMUNOMODULATORY ACTIVITY OF AQUEOUS ROOT EXTRACT OF ASPARAGUS RACEMOSUS WILLD AND ETHANOL WHOLE PLANT EXTRACT OF BOERHAVIA DIFFUSA LINN

Objective: On the basis of traditional use and Ethno pharmacological evidences Boerhavia diffusa whole plant and root part of Asparagus racemosus (Shatavari) both are widely used to enhance the immunity. But in combination there is no scientific evidence so current study was designed. Methods: Laboratory based study, namely, carbon clearance, cyclophosphamide induced immune suppression and neutrophil adhesion was designed using mice as an experimental animals in different combination of aqueous whole plant extract of B. diffusa and methanol extract of root part of A. racemosus were used as a test drug in the ratio 1:1, 1:2, and 2:1 (100 mg/kg) against the established standard drug Ashwagandha. Results: The results revealed that animals treated with combined extract (1:1, 1:2, and 2:1) at a dose of 100 mg/kg increase rate of carbon clearance from blood, there is significance alternation in blood parameter in cyclophosphamide group and also improve the Neutrophil adhesion when treated with different combination of polyherbal formulation treated groups. Conclusion: The polyherbal formulation in different ratio showing good significant immunomodulatory activity as compare to standard

Comparative efficacy of inhaled ciclesonide, budesonide, and fluticasone in mild to moderately persistent bronchial asthma

Background: Bronchodilators and glucocorticoids have been proven to be very effective and safe in asthma treatment, which recommend the use of steroids and β2-agonist (long or short acting) as the first line of treatment in of asthma. This study was aimed to compare the efficacy of three different inhaled corticosteroids ciclesonide, budesonide, and fluticasone in bronchial asthma.Methods: A total of 30 patients with mild to moderately persistent bronchial asthma was selected as per the NAEPP classification in the expert panel report (EPR) update 2002, NHLBL USA 2003. They were randomly divided into 3 groups of 10 patients each, and they were given 3 different steroid inhalers (ciclesonide or budesonide or fluticasone). Baseline and post-therapy spirometry were performed on day 1 and after 2 months and 6 months of treatment. Data were analyzed using SPSS software.Results: It was observed that most of the cases (43.3%) were between 26 and 35 years of age with female preponderance (56.6%). Significant symptomatic improvement was observed in all 3 groups. The percentage of improvement in mean peak expiratory flow rate was 17%, 18%, and 18% in ciclesonide, budesonide, and fluticasone group, respectively. The percentage improvement of forced expiratory volume in 1 second (FEV1)/forced vital capacity after bronchodilatation was 18%, 18%, and 19% in ciclesonide, budesonide, and fluticasone group, respectively. The improvement in mean FEV1% predicted was 20%, 19%, and 21% in three groups, respectively.Conclusion: Steroid therapy along with β2-agonists showed a significant improvement in symptoms. There was no difference among the three different types of steroids

Fluoroalcohol-induced modulation of the pathway of amyloid protofibril formation by barstar

To understand how the conformational heterogeneity of protofibrils formed by any protein, as well as the mechanisms of their formation, are modulated by a change in aggregation conditions, we studied the formation of amyloid protofibrils by barstar at low pH by multiple structural probes in the presence of hexafluoroisopropanol (HFIP). In the presence of 10% HFIP, aggregation proceeds with the transient formation of spherical oligomers and leads to the formation of both protofibrils and fibrils. Curly short protofibrils and fibrils are seen to form early during the aggregation reaction, and both are seen to grow gradually in length during the course of the reaction. Atomic force microscopy images reveal that the HFIP-induced protofibrils are long (~300 nm in length), curly, and beaded and appear to be composed primarily of β-sheet bilayers, with heights of ~2.4 nm. The protofibrils formed in the presence of HFIP differ in both their structures and their stabilities from the protofibrils formed either in the absence of alcohol or in the presence of a related alcohol, trifluoroethanol (TFE). Aggregation appears to proceed via an isodesmic polymerization mechanism. Internal structure in the growing aggregates changes in two stages during protofibril formation. In the first stage, an α-helix-rich oligomeric intermediate is formed. In the second stage, the level of β-sheet structure increases at the expense of some α-helical structure. The second stage itself appears to occur in two distinct steps. The creation of thioflavin T binding sites occurs concomitantly with aggregate elongation and is seen to precede the change in secondary structure. The long straight fibrils with characteristic heights of 8-10 nm, which form in the course of the HFIP-induced aggregation reaction, have not been observed to form either in the absence of alcohol or in the presence of TFE
