Medical uses Preoperative administration of<unk> 's solution decreases intraoperative blood loss during thyroidectomy in patients with Graves' disease. However, it appears ineffective in patients who are already euthyroid on anti-thyroid drugs and levothyroxine. *During colposcopy,<unk>  is applied to the vagina and cervix. Normal vaginal tissue stains brown due to its high glycogen content, while tissue suspicious for cancer does not stain, and thus appears pale compared to the surrounding tissue. Biopsy of suspicious tissue can then be performed. This is called a Schiller's test.<unk>  may also be used to better visualize the mucogingival junction in the mouth. Similar to the method of staining mentioned above regarding a colposcopy, alveolar mucosa has a high glycogen content that gives a positive<unk>  reaction vs. the keratinized gingiva.<unk>  may also be used as an oxidizing germicide, however it is somewhat undesirable in that it may lead to scarring and discolors the skin temporarily. One way to avoid this problem is by using a solution of 70% ethanol to wash off the<unk>  later.<unk>  was distributed in Polish People's Republic after the Chernobyl catastrophe, due to government not being informed of how severe the event was and overestimating radiation, and unavailability of<unk>  tablets. Science *As a mordant when performing a Gram stain. It is applied for 1 minute after staining with crystal violet, but before ethanol to ensure that gram positive organisms' peptidoglycan remains stained, easily identifying it as a gram positive in microscopy. *This solution is used as an indicator test for the presence of starches in organic compounds, with which it reacts by turning a dark-blue/black. Elemental<unk>  solutions like<unk> 's will stain starches due to<unk> 's interaction with the coil structure of the polysaccharide. Starches include the plant starches amylose and amylopectin and glycogen in animal cells.<unk> 's solution will not detect simple sugars such as glucose or fructose. In the pathologic condition amyloidosis, amyloid deposits (i.e., deposits that stain like starch, but are not) can be so abundant that affected organs will also stain grossly positive for the<unk>  reaction for starch. *It can be used as a cell stain, making the cell nuclei more visible and for preserving phytoplankton samples.<unk> 's solution can also be used in various experiments to observe how a cell membrane uses osmosis and diffusion.<unk> 's solution is also used in the marine aquarium industry.<unk> 's solution provides a strong source of free<unk>  and<unk>  to reef inhabitants and macroalgae. Although the solution is thought to be effective when used with stony corals, systems containing xenia and soft corals are assumed to be particularly benefited by the use of<unk> 's solution. Used as a dip for stony and soft or leather corals,<unk> 's may help rid the animals of unwanted parasites and harmful bacteria. The solution is thought to foster improved coloration and possibly prevent bleaching of corals due to changes in light intensity, and to enhance coral polyp expansion. The blue colors of Acropora spp. are thought to be intensified by the use of potassium<unk> .
