The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.

The main reason you stain a specimen before putting it under the microscope is to get a better look at it, but staining does much more than simply highlight the outlines of cells. Some stains can penetrate cell walls and highlight cell components, and this can help scientists visualize metabolic processes.

Used as a mordant in Gram’s staining, iodine enhances the entrance of the dye through the pores present in the cell wall/membrane. Lugol’s solution or Lugol’s iodine (IKI) is a brown solution that turns black in the presence of starches and can be used as a cell stain, making the cell nuclei more visible.

It reacts with starch and turns blue-black, because it is a starch indicator. When studying plant cells, iodine can stain not only starch, but also enters the cell wall-cell membrane pores and can facilitate the staining of the nucleus, rendering it more visible under the microscope.

1 Why did we add iodine to our cheek cells? We added iodine to our cheek cells so that we could see them when we put them under the microscope. the cells are naturally clear so in order to be able to see them the must be dyed.

To support growth and to strengthen plants Use the solution to water plant. Be careful not to spill it over the leaves and stalks, because even a moderate dose of iodine can burn the delicate parts of plants.

The natural iodine content in soil is low. While iodine is not an essential nutrient for plant growth, fertilizing with iodine derivatives has been shown to aid in biomass production and increase the antioxidant levels in plants which provide drought and stress resistance.

Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. It contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. It works by releasing iodine which results in the death of a range of microorganisms.

Povidone-iodine is a widely used and generally safe antiseptic, sclerotherapy, and contrast agent.

Ingestion can cause stomach upset, vomiting, diarrhea, and burns of the gastrointestinal tract. In excessive doses, there is a risk for iodine toxicity, which can lead to kidney failure, changes in electrolyte concentrations, or other organ failure.

A commonly used antimicrobial agent is povidone-iodine (Betadine), a complex of iodine, the bactericidal component, with polyvinylpyrrolidone (povidone), a synthetic polymer.

Iodine can be absorbed through intact skin in time dependent manner. In professional use the repetitive contact with PI, also as soap, can cause iodine skin permeation that must be considered when the washing procedures are repeated more than 20 times a day.

BETADINE Betadine works by releasing iodine which results in the death of a range of microorganisms. Since Betadine is sold over-the-counter, many people use this solution as a home remedy to prevent wound infection. Once again, however, experts agree that Betadine is too harsh to put on a healing wound.

Yes, it will kill some bacteria, but it also kills and irritates healthy skin and the wound bed. I suggest you do not use alcohol, hydrogen peroxide or Betadine solution in the open wound.”

Do not use topical iodine on deep, puncture wounds, animal bites, or serious burns. To do so may increase the chance of side effects. Do not cover the wound to which you have applied topical iodine with a tight dressing or bandage since this may increase the chance of side effects.

it should not be used for 4 weeks prior to treatment for cancer of the thyroid. povidone iodine preparations should not be applied over a long period and to large areas of the skin (e.g., not to more than 10% of the total body surface and for not longer than 14 days) unless strictly indicated.

What are the side effects of Betadine (Topical)?

• swelling, pain, warmth, redness, oozing, or other signs of infection;
• blistering or crusting; or.
• severe irritation, itching, or burning.

Antibiotic ointments (such as Neosporin) help wounds heal by keeping out infection and by keeping the wound clean and moist.

Neomycin frequently causes allergic reactions of the skin called contact dermatitis. It can cause the skin to become red, scaly, and itchy. The more Neosporin you use, the worse the skin reaction gets. Neomycin is such a common allergen that it was named Allergen of the Year in 2010.

Alternatives. Petroleum jelly products, such as Vaseline, can be good alternatives to bacitracin or Neosporin. The jelly keeps wounds from drying out, which can prevent or ease itching and other unpleasant symptoms.

Neomycin, an ingredient in Neosporin, is linked with a higher risk of allergic reactions. Still, any of the ingredients in these products can cause an allergic reaction. Both Neosporin and Bacitracin stop bacterial growth, but Neosporin can also kill existing bacteria.

The American Academy of Dermatology recommends petroleum jelly for keeping a wound moist and to help prevent it from drying out and forming a scab, because they take longer to heal. This will also help prevent a scar from getting too large, deep or itchy.

Continue applying the petroleum jelly until the wound has fully healed. Open wounds heal more slowly. A large wound can take 4 weeks or more to heal. A dressing (e.g. a plaster or gauze & tape) can be applied to protect the wound and keep it clean.

The vast majority of bacteria cannot *grow* in clean petroleum jelly. Yes, many bacteria and fungi can survive in petroleum jelly. So, if you touch your skin, then the petroleum jelly, your bacteria and fungi along with your dead skin cells will be on the jelly.
