Liver defend the PAMPs or DAMPs via regulation of innate immunity through modulation of “TOLL LIKE RECEPTORS and NOD LIKE RECEPTORS” A breakdown of tolerance may induce in appropriate immune response leads to acute and chronic liver diseases like NASH/NAFLD thus considered as disorders of immune response. HFD is itself a basic component for generating metabolic disorders and major source for formation of endotoxins in body through leaky gut and sensitization of the TLR4. NAFLD is one of the groups of disease which links the innate immunity through the metabolic disorder. Agonist of TLR4 – LPS is the primary and NLRP3 agonist MDP is secondary signal transducer for the sensitization of the Caspase activation cascade and TNFα activation serves as the proinflammatory cytokines in disease like NAFLD. The present study was elucidated to develop combinations of Lipopolysaccharide and Muramyl dipeptide induced experimental model of NAFLD in HDF fed rats. Various parameters such as body weight, SGOT, SGPT, ALP, Direct Billirubin, serum triglyceride, weight of liver, and ratio of liver...

Objective: The current study was designed to study Acute Dermal Irritation potential of Mastilep gel (supplied by M/S Ayurvet Limited, Baddi, India) according to OECD guidelines. Materials and Methods: Mastilep gel, a new herbal ointment for topical use applied on the udder, has been developed as an alternative method for controlling mastitis in ruminants. Mastilep gel’s active ingredients including herbal extracts of Cedrus deodara, Curcuma longa, Glycyrrhiza glabra and Eucalyptus globulus are expected for their antibacterial, anti-inflammatory, analgesic, antihistaminic and immunomodulatory effects. For new substances it is the recommended stepwise testing approach for developing scientifically sound data on the corrosivity/irritation of the substance. Three female rabbits were used for the study. Each animal served as its own control. After application of Mastilep gel the degree of irritation/corrosion was read and scored. Results: No severe erythema, oedema or any skin lesion was observed after Mastilep gel application. The results revealed no irritation potential of Mastilep gel. Conclusion: MASTILEP gel is safe for...

The present work aimed at formulating a solid self micro emulsifying drug delivery system (solid-SMEDDS) for Olmesartan Medoxomil with the objective of improving the aqueous solubility, dissolution and oral delivery of the drug. Liquid SMEDDS of the drug were formulated using Capmul MCM as the oil phase, Tween 80 and Phenoxide HCO-40 as the combined surfactants after screening various vehicles. The prepared systems were characterized for various physicochemical characteristics. Ternary phase diagrams were plotted to identify the area of micro emulsification. The optimized liquid SMEDDS was transformed into a free flowing powder using Neusilin US2 as the adsorbent. The physical state of the drug in solid self micro emulsifying powder was revealed by Differential Scanning Calorimetric and X– ray powder diffraction studies which indicated the presence of the drug in the dissolved form in the lipid excipients. These findings were supported by scanning electron microscopy studies which did not show the evidence of precipitation of the drug on the surface of the carrier. Moreover the droplet size of the...

Chalcones and its derivatives show various biological activities. The present study deals with the synthesis of series of 2-hydroxy-3-nitro-5-methyl–N-substituted phenyl chalcone imines from 2-hydroxy-3-nitro-5-methylphenyl chalcone and different substituted aromatic animes in ethanol in presence of 2, 3 drops of Conc. H2SO4. Structures of synthesized compounds have been established by spectral (IR, NMR, etc.) and elemental analysis. In the present communication we report the synthesis substituted chalcone imines and its antimicrobial activity against pathogenic bacteria and fungi. The sensitivity carried out by disc diffusion method displayed significant antimicrobial...

Five medicinal plants used in the traditional medicine of India, were selected for studying their immunomodulatory potential through the activation of macrophages, individually and in synergism. The plants were Boswellia serrata Roxb., Curcuma longa L., Glycyrrhiza glabra L., Tribulusterrestris L., and Tylophora indica (Burm f.) Merr. In the present study, strong stimulation of antigen specific and nonspecific immunity was evidenced by increase in phagocytic index, percentage inhibition of yeast digestion, macrophage activation and intracellular killing capacity of all the extracts individually and of their combination in murine model. All were found to increase in a dose dependent manner. The results provide scientific basis for widespread use of these plants and their combination as tonic for immunostimulation and chronic...
