Iodine in biology and the thyroid gland of rats. The role of iodine in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is unknown. It has been shown to act as an antioxidant and antiproliferant in various tissues that can uptake iodine. Molecular iodine (I) has been shown to have a suppressive effect on benign and cancerous neoplasias. The U.S. Food and Nutrition Board and Institute of Medicine recommended daily allowance of iodine ranges from 150 micrograms per day for adult humans to 290 micrograms per day for lactating mothers. However, the thyroid gland needs
Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde (MIF) is a solution used in biomedical laboratories for concentration of stool samples prior to microscopic investigation for parasites. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non-concentrated samples the likelihood of finding equivalents of actually present parasites is too low. MIF enables separation of different strata of stool matter, and sedimentation of stool particles that contain parasites (usually parasite eggs). After application of MIF, usually centrifugation is used for acceleration of sedimentation. The term "Merthiolate" indicates presence of thiomersal in the solution. Due to the hazardous qualities of thiomersal, it is
