Dextranomer

	Dextranomer Dextranomer (trade name Debrisan, Exudex) is a cicatrizant used in dressings for wound healing, and in pharmaceutical products to treat fecal incontinence. It consists of dextran polymer chains cross-linked into a three-dimensional network. Solesta Solesta is the marketed brand name of a system of injections of dextranomer in stabilized sodium hyaluronate for use in fecal incontinence (FI). This preparation is a biocompatible gel, for use as a perianal injectable bulking agent. The system is intended to be injected in the submucosal layer of the proximal anal canal (i.e. above the level of the dentate line The pectinate line (dentate line) is a line which divides the upper two-thirds and lower third of the anal canal The anal canal is the part that connects the rectum to the anus, located below the level of the pelvic diaphragm.

picture info	Fecal Incontinence Fecal incontinence (FI), or in some forms encopresis, is a lack of control over defecation, leading to involuntary loss of bowel contents, both liquid stool elements and mucus, or solid feces. When this loss includes flatus (gas), it is referred to as anal incontinence. FI is a sign or a symptom, not a diagnosis. Incontinence can result from different causes and might occur with either constipation or diarrhea. Continence is maintained by several interrelated factors, including the anal sampling mechanism, and incontinence usually results from deficiency of multiple mechanisms. The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectal surgery (especially involving the anal sphincters or hemorrhoidal vascular cushions), altered bowel habits (e.g., caused by irritable bowel syndrome, Crohn's disease, ulcerative colitis, food intolerance, or constipation with overflow incontinence), and receptive anal sex.

	Dextran Dextran is a complex branched glucan ( polysaccharide derived from the condensation of glucose), originally derived from wine. IUPAC defines dextrans as "Branched poly-α-d-glucosides of microbial origin having glycosidic bonds predominantly C-1 → C-6". Dextran chains are of varying lengths (from 3 to 2000 kilodaltons). The polymer main chain consists of α-1,6 glycosidic linkages between glucose monomers, with branches from α-1,3 linkages. This characteristic branching distinguishes a dextran from a dextrin, which is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages. Occurrence Dextran was discovered by Louis Pasteur as a microbial product in wine, but mass production was only possible after the development by Allene Jeanes of a process using bacteria. Dental plaque is rich in dextrans. Dextran is a complicating contaminant in the refining of sugar because it elevates the viscosity of sucrose solutions and fouls plumbing. Dextran is now produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Sodium Hyaluronate Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan found in various connective tissue of humans. Chemistry Sodium hyaluronate is the sodium salt of hyaluronic acid. It is a glycosaminoglycan and long-chain polymer of disaccharide units of Na-glucuronate-N-acetylglucosamine. It can bind to specific receptors for which it has a high affinity. The polyanionic form, commonly referred to as hyaluronan, is a visco-elastic polymer found in the aqueous and vitreous humour of the eye and in the fluid of articulating joints. Natural occurrence Sodium hyaluronate, as hyaluronic acid, is distributed widely in the extracellular matrix of mammalian connective, epithelial, and neural tissues, as well as the corneal endothelium. Mechanism of action Sodium hyaluronate functions as a tissue lubricant and is thought to play an important role in modulating the interactions between adjacent tissues. It forms a viscoelastic solution in water. Mechanical protection fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Anal Canal The anal canal is the part that connects the rectum to the anus, located below the level of the pelvic diaphragm. It is located within the anal triangle of the perineum, between the right and left ischioanal fossa. As the final functional segment of the bowel, it functions to regulate release of excrement by two muscular sphincter complexes. The anus is the aperture at the terminal portion of the anal canal. Structure In humans, the anal canal is approximately long, from the anorectal junction to the anus. It is directed downwards and backwards. It is surrounded by inner involuntary and outer voluntary sphincters which keep the lumen closed in the form of an anteroposterior slit. The canal is differentiated from the rectum by a transition along the internal surface from endodermal to skin-like ectodermal tissue. The anal canal is traditionally divided into two segments, upper and lower, separated by the pectinate line (also known as the dentate line): * upper zone (zo ...

Developmentally, this line represents the hindgut- proctodeum junction. It is an important anatomical landmark in humans, and several distinctions can be made based upon the location of a structure relative to this line: Additional images File:Rectoanal jxn.JPG, Microscopic cross section of the anorectal junction.
