People with colostomies must wear an ostomy pouching system to collect intestinal waste. Ordinarily, the pouch must be emptied or changed a couple of times a day depending on the frequency of activity; in general the further from the anus (i.e., the further 'up' the intestinal tract) the ostomy is located the greater the output and more ...

An enterostomy (entero-+ -stomy; / ɛ n t ə ˈ r ɒ s t oʊ m i /) is either (1) a surgical procedure to create a durable opening (called a stoma) through the abdominal wall into an intestine (small intestine or large intestine) or (2) the stoma thus created.
Micrograph of melanosis coli, with the characteristic mucosal lipofuscin-laden macrophages (brown).. Melanosis coli, also pseudomelanosis coli, is a disorder of pigmentation of the wall of the colon, often identified at the time of colonoscopy.
Many foods can change the color of the intestinal output, causing alarm; beetroot, for instance, produces a red output that may appear to be blood. [8] Nevertheless, people who have an ileostomy as treatment for inflammatory bowel disease typically find they can enjoy a more "normal" diet than they could before surgery. Correct dietary advice ...
Unlike negative staining, positive staining uses basic dyes to color the specimen against a bright background. While chromophore is used for both negative and positive staining alike, the type of chromophore used in this technique is a positively charged ion instead of a negative one. The negatively charged cell wall of many microorganisms ...
Surgical resection with permanent colostomies was the standard treatment until the 1970s, yielding 5-year overall survival of approximately 50%. The best overall survival rates are seen after combined radiation therapy combined with chemotherapy (5-FU + Mitomycin) in people with T2N0 and T3N0 categories of disease (5-y overall survival: 82% ...
The absence of color change in staining is named orthochromasia. The underlying mechanism for metachromasia requires the presence of polyanions within the tissue. When these tissues are stained with a concentrated basic dye solution, such as toluidine blue, the bound dye molecules are close enough to form dimeric and polymeric aggregates.
