1. A method is described for measuring the swelling pressure of solid gelatin. 2. It was found that this pressure increases rapidly between 15 degrees and 37 degrees C., and that the percentage change is nearly independent of the concentration of gelatin. 3. It is suggested that this pressure is due to the osmotic pressure of a soluble constituent of the gelatin held in the network of insoluble...

To improve the in vivo resorption of an injectable calcium phosphate cement (CPC) for bone tissue engineering purposes, in previous experiments macroporosity was introduced by the in situ degradation of incorporated gelatin microspheres. Gelatin microspheres are also suitable carriers for osteoinductive drugs/growth factors, where release occurs concomitantly with degradation of the hydrogel. I...

In this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nHAp) composites. Cell culture and MTT assays were performed for in vitro biocompatibility. They show that nHAp can affect the proliferation of cells and the nHAp-starch and nHAP-gelatin biocomposites have no negative effect on the cell morphology, viability and p...

Many works have appeared in various scientifically reputable journals and publications worldwide that seem to have made potential or satisfactory contribution to our knowledge on the functions and utilization of gelatin--an important source of animal protein. Irrespective of these worldwide publications, room still exists for more work to be done to fully understand the utilization, chemical, b...

Gelatin, a biopolymer derived from animal proteins, has been selected to stabilize three fine-grained soils by determining select index and engineering properties. Specimens for California Bearing Ratio (CBR) were tested using different curing methods, i.e., thermally cured at 60 °C, unsoaked, 7 days air-cured submerged specimens. The amount of gelatin added the soil ranged 0.5% 2% weight. sequ...

     Production and characterization of soft cross-linked gelatin sponge by using glutaraldehyde for blood hemostasis application, is the goal of this study. Biodegradable hydrogels were prepared through crosslinking of gelatin with glutaraldehyde followed by freeze drying. The effects of gelatin concentration, amount of crosslink agent and freeze drying temperature on mechanical properties and...

Background and Objective: Poly D,L-lactic-co-glycolic acid (PLGA) is known as biodegradable and biocompatible polymer. These polymers have recently received much attention in tissue engineering. The aim of this study was to investigate the biological behavior of the bone marrow stromal cells (BMSCs) in culturing with PLGA nanofibers coated with poly-L-lysine or gelatin. Materials and Methods: I...

Sugar Fermentation Tests The media are prepared from Coignet's gold medal gelatin in a manner similar to that described for the liquefaction test. Instead of sheet gelatin, Difco nutrient gelatin in about double strength poured out to form sheets can also be used with equally satisfactory results. After formolization the gelatin sheets are cut or punched into shapes, about 15 mm. diameter, conv...
