Background: Berberine is a natural alkaloid used as traditional Chinese medicine. Objective: The objective of the present study was to evaluate the effect of berberine on dibutyltin dichloride (DBTC) induced acute pancreatitis in albino Wistar rats. Methods: In this study 24 Wistar rats were randomly selected and divided into four groups. Each group consists of 6 animals. Group-1 (-ve control), Group 2 (+ve control or disease control), Group 3 (Berberine 50 mg/kg p.o), Group 4 (Berberine 100 mg/kg, p.o). Acute pancreatitis was induced with dibutyltin dichloride at a single dose of 6mg/kg body weight i.p to all the groups except negative control. At 3rd day, serum amylase and lipase levels were elevated in all groups except negative control meanwhile rats were treated with berberine up to 28 days. The estimation of blood parameters and tissue parameters was carried out by the auto-analyzer. Results: Berberine treated groups significantly reduce elevated serum parameters, and significantly increase the tissue antioxidant parameters to normal. Serum parameters like serum amylase, lipase, fasting blood glucose...

Objective: Nanoliposomes of letrozole a drug used for breast cancer treatment were formulated. The present investigation was aimed to optimize the phospholipids concentration by formulating a series of nanoliposomes formulation and their characterization. Methods: Nanoliposomes were prepared using reverse-phase evaporation technique employing diverse ratios of soya lecithin and cholesterol concentration. The effect of various factors was studied on size, polydispersity index, loading capacity and entrapment efficiency of nanoliposomes. The prepared nanoliposomes were analyzed using DSC and ATR spectroscopy for drug-excipients compatibility. Results: The smallest particle size and polydispersity index (99.45, 0.262) highest entrapment (87.24 ± 0.59) and loading capacity (56.89 ± 0.39) was observed in batch NL8. The disappearance of drug peak in DSC indicates the dissolution of the drug in a polymer matrix. The ATR spectroscopy results show there was no interaction between components and drug is stable in the formulated nanoliposomes. Conclusion: It is concluded that the concentration of soya lecithin and cholesterol were critical parameters that affect the encapsulation of letrozole in the formulation and optimization...

Rheological properties of carboxymethyl locust bean gum (CMLBG) solutions having different concentrations and solution pH were evaluated through steady shear and oscillatory measurements and were used to describe the erosion propensity of CMLBG coat of compression coated placebo tablets. CMLBG solutions, irrespective of concentration and solution pH, exhibited predominant viscous character as the viscous modulus (G”)> elastic modulus (G’) and phase angle (Tan δ) > 1. The viscous contribution was found to be influenced by both the CMLBG concentration and solution pH. An increase in CMLBG concentration increased the pseudo-plasticity and consistency coefficient and decreased the viscous contribution in all solution pH resulting in a decrease in erosion of CMLBG coat. The higher viscous character of CMLBG in buffer solution of pH 7.4 (Solution B) was responsible for higher erosion of the coat than in acid solution of pH 1.2 (Solution A). When the pH of acid solution of CMLBG was increased dynamically from 1.2 to 7.4, the viscous contribution decreased to some extent than that observed in Solution...

Cold and hot methanolic extract of leaves and whole plant parts of Andrographis paniculata were tested against gram-negative Escherichia coli (MTCC 1679) Klebsiella pneumonia (MTCC 4032) Streptococcus pyogenes, Solmonella typhimurium (MTCC733) and gram-positive Staphylococcus aureus (MTCC737). Maximum activity among all the bacterial cultures tested was showed against E. coli MTCC1679 when compared with their standards. Next to E. coli, MTCC1679 best inhibition was seen against S. aureus (MTCC737). There was no inhibition reported against, K. pneumonia, S. pyogenes, Salmonella typhi. The studied result revealed the highest activity in 75% methanolic extract. The highest zone of inhibition (22 mm) was observed against E. coli at a dose of 3.0 mg. The antibacterial activities of 75% methanol extract from A. paniculata leaves were observed only against the E. coli. The extract was not found active against other tested bacterial pathogens. The Andrographolide compound was analyzed by HPLC chromatogram and the standard of the given andrographolide compound was also prepared by the...

A major challenge in treating bacterial infections is the increasing incidence of microbial resistance to antibiotics. This poses a serious threat prompting the search for alternative strategies to treat bacterial infections. Metal nanoparticles as novel antibiotic agents hold promise because they show strong antibacterial activity against various bacterial species, including Gram-positive and Gram-negative bacteria. Green synthesis of nanoparticles offers minimization of wastage, reduction of derivatives, use of non-toxic solvent, auxiliaries and renewable feedstock. A single step, an eco- friendly, cost-effective method is used for the synthesis of copper nanoparticles (CuNPs) from 1.0 mM copper sulphate solution using extract of Ocimum sanctum (Tulsi) leaves as reducing and capping agent. UV-VIS, FESEM, FTIR and XRD were used to confirm and characterize the NPs. The biosynthesized copper NPs were phased pure and well crystalline with a simple cubic structure. Antibacterial study of the biogenic CuNPs suggests their efficacy against common human bacterial pathogen species. Gram-negative test organisms were found to be more susceptible to toxicity of biosynthesized CuNPs. Metal nanoparticles hold the...
