Nutritional deficiencies Prevention and Treatment Thiamine was one of the first compounds recognized as a vitamin. Thiamine is involved in many body functions, including nervous system and muscle function, the flow of electrolytes in and out of nerve and muscle cells, digestion, and carbohydrate metabolism. Very little thiamine is stored in the body and depletion can occur within 14 days. Severe thiamine deficiency may lead to serious complications involving the nervous system, brain, muscles, heart, and stomach and intestines. Dietary sources of thiamine include beef, brewer's yeast, legumes (beans, lentils), milk, nuts, oats, oranges, pork, rice, seeds, wheat, whole-grain cereals, and yeast. In industrialized countries, food made with white rice or white flour is often enriched with thiamine.

- Dilation, or widening, of the pupils of the eyes is normal in conditions of low light in order to allow more light to reach the retina. Medically, dilation of the pupils is known as mydriasis.Specific medications known as mydriatics are administered to dilate the pupils for ophthalmologic examination.If the pupils are dilated due to an abnormal response, they may remain dilated even in the presence of sunlight or strong light.Injury to the brain and taking certain drugs are common causes of abnormally dilated pupils. Both medications and drugs of abuse can result in dilated pupils.Dilation of the pupil on one side only is also abnormal and may signal a brain injury or other condition that raises the pressure within the cranial cavity (increased intracranial pressure).f the pupils are dilated due to an abnormal response, they may remain dilated even in the presence of sunlight or strong light. Injury to the brain and taking certain drugs are common causes of abnormally dilated pupils. Both medications and drugs of abuse can result in dilated pupils.
