Gliclazide is a Hypoglycemicdrug, second-generation sulfonylurea used in the treatment of non insulin dependent diabetes mellitus. Gliclazide exhibit poor aqueous solubility, so that their low bioavailability. Objectivesthis study is to develop solid self-emulsifying (SE) microparticles of poorly soluble gliclazide to dissolution enchancement. These microparticles were prepared by spray drying method, using three surfactant (acripol, tween 80 and sodium lauryl sulphate) with various concentration. SE microparticles characterized in terms of morphology (SEM), particle size distribution (PSA), x-ray diffraction (XRD), thermal analysis (DSC), functional group analysis (FTIR), solubility test, and dissolution test. The all gliclazide SE microparticlesexhibited particle size smaller than pure …

Nitrosodimethylamine is a carcinogenic compound which can be formed from the reaction of nitrite and dimethylamine that is found in food. Nitrosodimethylamineis activated in liver and alkylates the DNA base and producing a DNA adductssuch as O6-methylguanine and N7-methylguanine that have a role incarcinogenesis. In this research, DNA was isolated from rat’s blood which waspreviously given nitrosodimethylamine’s precursor, sodium nitrite anddimethylamine. DNA adducts can be obtained from hydrolysis in hydrochloricacid 0.1 N for 30 minutes at 7000C. Then the adducts were analyzed using High Performance Liquid Chromatography (HPLC), with a strong cation exchangecolumn (Supelcosil LC-SCX, 5 μm, 250 x 4.6 …

Some diseases, such as cancer, hereditary and genetic diseases, as well as viral infectious diseases, have been treated unsatisfied by the conventional therapy so far, and even more, by the gene therapy. Together with the pharmaceutical industries, researchers put their best effort to hunt some molecules that can be more favorable for such kind of therapy. After a pivotal study reported in May, 2001, it is certain that Ribonucleic acid (RNA) could effectively silence gene expression in mammalian cell line, so it was then proposed in 2004 the term RNA therapeutics. Antisense RNA therapy which came into the stage earlier …

Niosomes are non ionic surfactant vesicles that have potential application in the delivery of hydrophobic or amphilic drugs. We developed proniosomes, a dry formulation using a maltodextrin as a carrier coated with non ionic surfactant, which can be used to produce niosomes within a minutes by addition of hot water followed by agitation. A novel method is reported here for rapid preparation of proniosomes with wide range of surfactant loading. Maltodextrin DE 5-10 was hidrolyzed from tapioca starch using Thermamyl L 120 da Novo at 85ºC. The result from SEM analyses shown that proniosomes appear very similar to the maltodextrin, …

Vaccines have played an important role in preventive medicine since Edward Jenner discovered that cowpox induced protection against human smallpox. Until recently, a vaccination has meant a needle in the arm. However, with the increasing need for inexpensive, easily administered vaccines, along with the improvements in genetic engineering, the concept of edible vaccines is fast becoming reality. This is especially important in developing countries, where it is estimated that three to five million children die each year from common diseases, which could have easily been prevented with the proper vaccination. Compared to traditional lab-synthesized vaccines, plants are capable of producing …
