The aim was to prepare cross linked polymer of 5-fluorouracil loaded microspheres containing guar gum and sodium borate for colon-targeted drug delivery systems. Micro spheres were prepared using emulsification cross linking method. The influence of drug polymer ratio, cross linker agent concentrations and cross linking timing on in vitro drug release and characteristics in terms of drug loading, entrapment efficiency and yielding percentage were investigated. The optimum drug loading, entrapment efficiency and percent yield were obtained from formulations with the lowest content of cross linker agent over 2 h of cross linking timing but with the highest drug to polymer ratio 1:11...

The present study investigated the feasibility of using combination of Cationic and anionic polymers as sustained release carrier for the delivery of high dose gastric acid soluble model drug Paracetamol. Various formulations were prepared using wet granulation technique. Briefly a cooled (4°C) neutral solution of chitosan (CH) was combined with cooled aqueous solution (4°C) of anionic polymer such as Gum Ghatti (GG) and Xanthan gum (XG). This polyelectrolyte solution was then used to granulate the model drug Paracetamol...

We report the serotyping of foot-and-mouth disease virus (FMDV) and Pasteurella multocida from Indian gaurs which were concurrently infected with foot-and-mouth disease (FMD) and haemorrhagic septicaemia. Bannerghatta biological park (BBP), a national park located in the outskirts of Bengaluru city, Karnataka, India, is bordered by several villages. These villages witnessed massive outbreaks of FMD which spread rapidly to the herbivores at BBP. Post-mortem was conducted on carcasses of two Indian gaurs that died with symptoms of FMD...

Diabetes mellitus (DM) and hypertension are two common diseases that often coexist. The most common cause of death in the diabetic patient is heart disease. In the present investigation we combine Nebivolol and Nateglinide for better patient compliance. IR layer was formulated using various superdisintegrants like Crospovidone, Croscarmellose sodium, and sodium starch glycolate and SR layer was formulated using polymers and gums like HPMC E15, ethyl cellulose, Gaur gum, and Xanthan gum. The disintegration and dissolution study of both layers showed that inclusion of surfactant (sodium lauryl sulphate) to the tablet formulation (IR) and dissolution medium (SR) enhanced the release of drugs from both layers...

CONTEXT: Most new drugs have low water solubility and liposome is an important formulation to administer such drugs; however, it is quite unstable and has negligible systemic absorption. OBJECTIVE: Aceclofenac nanovesicles were made using guggul lipid for formulating stable transdermal formulation. MATERIALS AND METHODS: Guggul lipid was formulated into vesicles along with cholesterol and dicetyl phosphate using film hydration method. The formulations were analyzed for physicochemical properties and stability...

Natural carbohydrates (polysaccharides): gum acacia (GA) and gaur gum (GG) were employed in dilute solutions: 0.3%, 0.5% and 0.7% (w/v), as effective reductants for the green synthesis of silver nanoparticles (AgNPs) from AgNO3. The formed AgNPs were impregnated into cellulose fibers after confirming their formation by utilizing ultraviolet-visible (UV-vis) spectral studies, Fourier transforms infrared (FTIR) and transmission electron microscopy (TEM). The surface morphology of the developed cellulose-silver nanocomposite fibers (CSNCFs) were examined with scanning electron microscope-energy dispersive spectroscopy (SEM-EDS)...

Different biopolymers, agar, cellulose, alginate, psyllium gaur gum, and bacterial exopolysaccharide (EPS) powders were amended to check their efficacy in enhancing maximum water holding capacity (MWHC), permanent wilting point (PWP), and germination and seedling growth of the Gossypium herbaceum in a laboratory scale. The efficacy of all biopolymers for enhancement of MWHC, PWP, and growth was also analyzed by measuring organic carbon, organic matter, total nitrogen, respiration rate, and microflora in amended and control sandy loams...

The present investigation explored the use of xanthan gum and guar gum for development of floating drug delivery system of dipyridamole using factorial design approach. The content of polymer blends (X(1)) and ratio of xanthan gum to guar gum (X(2)) were selected as independent variables. The diffusion exponent (n), release rate constant (k), percentage drug release at 1 hr (Q(1)) and 6 hr (Q(6)) were selected as dependent variables. Tablets of all batches had desired buoyancy characteristics. Multiple regression analysis with two way ANOVA revealed that both the factors had statistically significant influence on the response studied (p<0...

OBJECTIVE: To evaluate the scientific evidence on guggul for hyperlipidemia including expert opinion, folkloric precedent, history, pharmacology, kinetics/dynamics, interactions, adverse effects, toxicology, and dosing. METHODS: Electronic searches were conducted in nine databases, 20 additional journals (not indexed in common databases), and bibliographies from 50 selected secondary references. No restrictions were placed on language or quality of publications...

An unexpected mortality of more than 300 cattle was investigated near a metal recovery factory located in a rural area of the Thane district of India. The factory was engaged in reclaiming lead, aluminum, tin, and zinc from discarded lead storage batteries and soft drink cans. The environmental samples (soil, leaves, grass, slag, water, and sediment), human blood and hair and animal samples (blood, urine, peritoneal fluid, liver, kidney, cow dung, ribs, and femur), collected for analysis revealed toxic levels of lead, cadmium, and chromium...
