Apart from imidazole derivative e.g. metronidazole, tinidazole, nimorazole etc. and other agents such as hydroxy quinolines, iodine preparation (povidoneiodine) and antifungal antibiotics e.g. clotrimazole (used mainly as vaginal pessaries), there are some other compounds which are mainly used in the treatment of trypanosomiasis. They are ... 

Pour water into two test tubes and lower one crystal of the iodine prepared in the preceding experiments into each of them. Vigorously shake the contents of the tubes. What is the solubility of iodine in water Write the equation of the reaction of iodine with water.

Data on the chemical stability at room temperature have been compiled almost exclusively for vitamins. A stress test was almost always performed for PVP-iodine preparations, and this corresponds to at least one year at room temperature. 

Equip a 2-litre three-necked flask as above the solids addition system is not required but the gas inlet system described below should be assembled for use in the latter stages of the experiment. An appropriate water bath should be used for heating. Place 37.5 g (1.54 mol) of washed and dried magnesium turnings and 300 ml of sodium dried ether in the flask and add a small crystal of iodine. Prepare a solution of 205.5 g (161 ml, 1.50 mol) of pure dry butyl bromide (Expt 5.54) in 300 ml of dry ether in the separatory funnel and introduce about 25 ml of the solution into the flask. As soon as the reaction commences (disappearance of the iodine colour), set the stirrer in motion and add...

Superficial bacterial infections, e.g. impetigo, eczema, are commonly staphylococcal or streptococcal. They are treated by a topical antimicrobial for less than 2 weeks and applied twice daily after removal of crusts that prevent access of the drug, e.g. by a povidone-iodine preparation. Very extensive cases need systemic treatment. 

In conclusion, therefore, several groups of investigators have produced antisera which they find useful for the work which they propose to undertake. No systematic experiments have yet been carried out with these antisera to determine whether the specificity of radioimmunoassays for FSH and LH changes when hormones purified by different procedures are employed for the label. As shown in Section 2 there is a large variety of methods in current use for the preparation of the pituitary hormones, and there is evidence that the final products are not identical (see Tables 3 and 4). Accordingly, it is likely that different iodinated preparations will yield different results. In this connection Ryan (R24) found that several human pituitary LH preparations, all made by the same method, showed different cross-reactions with HCG in the presence of the one antiserum. 

Use of the rat liver plasma membrane RRA was introduced by Megyesi et cd. (Mil, M12). Although these membranes possess receptors for both IGF-I and IGF-II related peptides (K3), IGF-II receptors predominate (M7). The tracer used in the original studies (Mil) was an iodinated preparation of NSILAs, a mixture containing both IGF-I and IGF-II (Z5), which might be expected to bind to both receptor types. Specificity studies with this tracer... 

There are many iodine-containing pharmaceuticals that can cause thyroid dysfunction. The majority of patients with such drug-induced thyroid dysfunction are found among those treated with inorganic iodine preparations, such as potassium iodide, sodium iodide, hydrogen iodide, or Lugols solution (Wolff, 1969 Fradkin and Wolff 1983). These days, however, the major sources of iodine... 

Daily Betadine douches would increase pain and discomfort. Betadine is an iodine preparation and could cause the area to sting. The client should be encouraged to limit use of any soap or chemical preparation until released to do so by the HCP.
