background: in this study the basic radiation properties of n-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. materials and methods: the nipam gel was prepared and irradiated approximately 2 h after manufacturing. the magnetic resonance (mr) images were made 24 h after irradiation. the nuclear magnetic resonance (nmr) respons...

The aim of the present investigation was to develop and study topical gel delivery of curcumin for its anti-inflammatory effects. Carbopol 934P (CRB) and hydroxypropylcellulose (HPC) were used for the preparation of gels. The penetration enhancing effect of menthol (0-12.5% w/w) on the percutaneous flux of curcumin through the excised rat epidermis from 2% w/w CRB and HPC gel system was investi...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...

The present study was aimed at developing aqueous dispersion of Ketorolac-loaded solid lipid nanoparticles (SLN) by high speed stirring followed by ultrasonication technique and then incorporation into freshly prepared gel for transdermal delivery. A statistical central composite design was applied to study the effect of drug/lipid ratio and soya lecithin concentration on particle size and entr...

Aloe vera gel of 50% and 96.4% were tested for its wound healing activity by topical application in experimental rats. The effect of Aloe vera gel on wound healing was evaluated by wound excision model and histopathology was used to study the effect on wound healing. The effect produced by Aloe vera gel with reference to wound contraction, wound closure, decrease in surface area of wound, tissu...

sol–gel chemistry is an efficient tool to control the morphology and reactivity of solids. drying is the crucial step due to the capillary forces exerted during the classic ambient drying process, which induces the collapse of the wet gel porosity. the use of n, n-dimethylformamide (dmf), a newly found dcca were found to be effective in the sol–gel synthesis of crack-free silica gel monolith fr...

piroxicam is a non-steroidal anti-inflammatory agent which has an extensive use in rheumatic disorders. since its skin penetration is still a subject for research, the aim of this study was to evaluate the effect of dimethyl sulfoxide on percutaneous penetration of piroxicam gel formulation through skin. in this study, as a model, two types of 0.5% piroxicam new gels, so called red and green ge...
