Using incision, excision and dead space wound models in rats, a study was conducted on the effect of histamine on wound healing. Exogenous histamine given either ip or locally was without any effect. Semicarbazide as (histamine synthesis inhibitor) suppressed healing process (breaking strength of skin incision wound), decreased breaking strength and hydroxyproline content of granulation tissue ...

Abrading decreases the strength of glass at these low temperatures in the same wayas at higher temperatures. Lowering the test temperature increases the strength, up to a point, of both abraded and unabraded specimens. The breaking stress at 194°K and 296 K is dependent on the rate of loading but appears to be independent of the rate at 20 0 K and 76°K. Contact with liquid nitrogen and hydrogen...

Aqueous extract of leaves of M. oleifera was investigated and rationalised for its wound healing activity. The aqueous extract was studied at dose level of 300 mg/kg body weight using resutured incision; excision and dead space wound models in rats. Significant increase in wound closure rate, skin-breaking strength, granuloma breaking strength, hydroxyproline content, granuloma dry weight and d...

Using a phenotype driven n-ethyl-nitrosourea (ENU) screen in growth hormone-deficient mice, we have identified a mutant (named 14104) that exhibited a smaller bone size. Phenotype measurements by microcomputed tomography revealed that mutant mice exhibited a 43 and 34% reduction in tissue area and bone area, respectively at the femur middiaphysis. Dynamic histomorphometry revealed a 30 and 15% ...

the study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. the breaking load, tens...

Low circulating IGF-I is associated with increased fracture risk. Conditional depletion of IGF-I produced in osteoblasts or osteocytes inhibits the bone anabolic effect of mechanical loading. Here, we determined the role of endocrine IGF-I for the osteogenic response to mechanical loading in young adult and old female mice with adult, liver-specific IGF-I inactivation (LI-IGF-I(-/-) mice, serum...

Atomic minerals are the smallest components of bone and the content of Ca, being the most abundant mineral in bone, correlates strongly with the risk of osteoporosis. Postmenopausal women have a far greater risk of suffering from OP due to low Ca concentrations in their bones and this is associated with low bone mass and higher bone fracture rates. However, bone strength is determined not only ...
