glycolic acid/necrosis

Retinoic acid (RA) and glycolic acid (GA) are frequently used in the treatment of acne and skin aging, as well as improving skin healing after dermabrasion and in photoaged skin. Examples of histologic alterations caused by these substances are vascularization increase and interference with

OBJECTIVE To observe the effect of recombinant human bone morphogenetic protein 2/poly-lactide-co-glycolic acid (rhBMP-2/PLGA) with core decompression on repair of rabbit femoral head necrosis. METHODS Bilateral femoral head necrosis models of rabbit were established by steroid injection. A total of

The dissolution properties of two model compounds, brilliant blue and tumour necrosis factor (TNF-alpha), from poly(D,L-lactic-co-glycolic acid) (PLGA) multiphase microspheres were investigated. In addition, the in vivo release of TNF-alpha from the microspheres, in mice, was studied. The

A DNA vaccine against infectious haematopoietic necrosis virus (IHNV) is effective at protecting rainbow trout, Oncorhynchus mykiss, against disease, but intramuscular injection is required and makes the vaccine impractical for use in the freshwater rainbow trout farming industry. Poly

Mucous-penetrating nanoparticles consisting of poly lactic acid-co-glycolic acid (PLGA)-polyethylene glycol (PEG) could improve targeting of microbicidal drugs for sexually transmitted diseases by intravaginal inoculation. Nanoparticles can induce inflammatory responses, which may exacerbate the

Poly(lactide-co-glycolic acid) (PLGA) has been widely applied to tissue engineering as a good biocompatible material because of its biodegradability and nontoxic metabolites, but how the inflammatory reaction of PLGA on the surrounding tissue in vivo is reduced has not been discussed sufficiently.

Our study is aimed at evaluating the effects of pretreatment with Poly(lactic-co-glycolic) acid nanoparticle loaded with resveratrol (RSV PLGA NPs) compared to conventional resveratrol (RSV) on isoproterenol (ISO) induced myocardial infarction (MI) in rats. Sixty rats were randomly divided into six

Chronic inflammatory diseases are associated with increased soluble tumour necrosis factor (TNF) receptor concentrations in serum. To obtain such an increase, we implanted mice with ethylene vinyl-acetate or poly (lactic-co-glycolic) acid copolymers containing human soluble p55 TNF receptor.

OBJECTIVE Poly(lactic-co-glycolic acid) (PLGA), a biodegradable polymer, is a carrier for drug delivery systems. This study was undertaken to investigate the tolerogenic effect of single administration of PLGA entrapping type II collagen (CII) on the development of collagen-induced arthritis

Celecoxib (CEL) is a nonsteroidal anti-inflammatory drug (NSAID) showing selective cycloxygenase-2 inhibition. While effective as a pain reducer, CEL exerts some negative influence on renal and gastrointestinal parameters. This study examined CEL pharmacodynamics and pharmacokinetics following drug

Objective: To prepare the Fe3O4-loaded biodegradable liquid-solid phase inversion poly(lactic-co-glycolic acid) (PLGA) in situ implant for ultrasound-guided injection into nude mouse tumor model, and to investigate its clinical effect in thermomagnetic treatment of nude mice with human liver cancer

METHODS The effects of a low, local dose of a tumor necrosis factor-alpha (TNF-alpha) inhibitor on neuropathic pain behaviors in a rat chronic constriction injury model were evaluated. OBJECTIVE To investigate whether a peripherally implanted polymer drug depot can deliver a dose of etanercept

Glycolic acid is a member of the AHA family, which occurs naturally in foods and has been used for centuries as a cutaneous rejuvenation treatment. Recently it has proved to be a versatile peeling agent and it is now widely used to treat many defects of the epidermis and papillary dermis in a

BACKGROUND Seventy percent glycolic acid solutions are being commonly used as superficial chemical peeling agents. The pH of these solutions ranges from 0.08 to 2.75. The histologic effects of these various pH solutions on human skin have not been studied. OBJECTIVE The histologic effects of several

OBJECTIVE To determine whether a synthetic ultrasonographic (US) contrast agent can be used to differentiate coagulation necrosis from untreated tumor immediately after radio-frequency ablative therapy. METHODS VX2 (adenocarcinoma) tumors (0.8-1.5-cm diameter) were implanted into 12 rabbits.
