wound healing in the skin depends upon the availability of appropriate trace metals as enzyme cofactors and structural components in tissue repair. the present study is a part of a series of experimental investigations to examine the influence of bentonite on skin wound healing. surgically induced skin wounds in 48 young adult male rats were exposed topically to bentonite (12 round wound and 12...

Injection drug users (IDUs) in San Juan, Puerto Rico are characterized by high rates of daily injecting, injection of shared drugs, re-use of injection syringes, and use of shooting galleries. They lack adequate access to new injection syringes and drug preparation equipment, and experience elevated rates of HIV and HCV infection. Between April and August, 2006, researchers and active IDUs coll...

purpose: to evaluate the effects of intravitreal and intracameral injection of bevacizumab in patients with neovascular glaucoma (nvg).   methods: this interventional case series was conducted on 40 eyes of 40 patients with neovascular glaucoma. data included the extent of iris (nvi) and angle neovascularization (nva), peripheral anterior synechia (pas), and intraocular pressure (iop). followin...

Fault injection provides a method of assessing the dependability of a system under test. Traditionally fault injection is employed near the end of the design process after hardware and software prototypes have been developed. In order to eliminate costly re-designs near the end of the design process, a methodology for performing fault injection throughout the design process is described in this...

we studied the effects of a single ketamine injection in an experimental model of chronic hypernatraemia in rats. three groups, each of 20 male wistar rats were chosen for the experiment; the control group was given water and the test groups were given 1% (group 1) and 2% (group 2) nacl solutions for two weeks. all groups were fed with the same diet, containing about 0.5% salt. other living con...

background: the areas of the bed nucleus of the stria terminalis (bst) with a high density of estrogen receptors are involved in cardiovascular regulation and send axonal projections to the rostroventrolateral medulla (rvlm). we aimed to find the contribution of the rvlm to cardiovascular responses elicited by glutamate microinjection into the bst. methods: experiments were done in α-chloralose...

RIGGI, S. J. AND N. R. DI LUZIO. Identification of a reticuloenduthelial stimulating agent in zymosan. Am. J. Physiol. zoo(z) : 297-300. 1961. -The functional activity of the reticuloendothelial system (RES), as determined by the intravascular clearance of colloidal carbon, and the degree of induced RE hyperplasia were studied following the intravenous injection of various constituents of zymos...

The mechanism of the reticuloendothelial "blockade" which followed injection of large quantities of chromic phosphate without exogenous stabilizing material was investigated in Wistar rats. The RE blockade observed for several hours after induction appeared related to the continuing circulation of the chromic phosphate-blockading dose, and a reduction in the size of the particles used enhanced ...
