Hormones and Endocrine Drugs

Progesterone (also known as progesterone, geststerone, luteosterol, progesterone, progesterone, progesterone, progesterone, progesterone, progesterone, lutein or progesterone, abbreviated as P4, also known as (gesterol-4-ene-3,20-dione), is an endogenous steroid and progesterone sex hormone, and also the main pregnancy hormone in the body, secreted by the female ovary. Progesterone is a steroid hormone with 21 carbon atoms secreted by ovarian luteal cells, and is also the intermediate product of all steroids, which belongs to progesterone. There are two types of crystal, namely α- Type and β- The two types have the same physiological activity of , α- The type is precipitated from dilute ethanol and is a white prism crystal of orthorhombic system, β- The results showed that the crystal was of the orthogonal crystal system, which was white needle crystal, neither of them was soluble in water, and was soluble in ethanol, ether, chloroform, acetone, dioxane and sulfuric acid.

Therapeutic Hydrocortisone is a synthetic or semisynthetic analog of natural hydrocortisone hormone produced by the adrenal glands with primary glucocorticoid and minor mineralocorticoid effects. As a glucocorticoid receptor agonist, hydrocortisone promotes protein catabolism, gluconeogenesis, capillary wall stability, renal excretion of calcium, and suppresses immune and inflammatory responses.

Potassium iodide is an ionic compound, in which iodide ion and silver ion can form a dark yellow precipitate silver iodide (see light decomposition, can be used to make high-speed photographic film), so silver nitrate can be used to test the existence of iodide ion. Iodine, as a component of thyroxine, is closely related to the basic metabolism of livestock and poultry, and participates in almost all material metabolism processes. Iodine deficiency in livestock can cause thyroid hyperplasia and hypertrophy, decrease the basic metabolic rate, and affect growth and development. It is necessary to add iodine in the feed of young livestock and livestock in iodine deficient areas. The iodine requirement of high-yield dairy cows and high-yield laying hens is increased, and iodine is also needed in their feed. The iodine in milk and eggs increased with the increase of feed iodine. It is reported that high iodine egg can reduce the cholesterol content of human body, which is beneficial to the health of patients with hypertension. In addition, during the period of animal fattening, although there is no iodine deficiency, in order to make the thyroid function of livestock and poultry exuberant, enhance the ability of anti stress, and maintain the highest production capacity, iodide is also added. Potassium iodide as an iodine source is added to the feed, which can prevent iodine deficiency, promote growth, increase the rate of egg production and reproduction, and improve the utilization rate of feed. To sum up, potassium iodide is commonly used as analytical reagent, photographic emulsifier preparation, pharmaceutical industry, as well as photographic emulsion, soap, lithography, food additives, etc.

Inositol is a natural sugar found in cell membrane phospholipids, plasma lipoproteins, and (as the phosphate form) in the nucleus with potential chemopreventive properties. As one of a number of intracellular phosphate compounds, inositol is involved in cell signaling and may stimulate tumor cell differentiation. Inositol is a collection of nine different stereoisomers but the name is usually used to describe only the most common type of inositol, myo-inositol. Myo-inositol is the cis-1,2,3,5-trans-4,6-cyclohexanehexol and it is prepared from an aqueous extract of corn kernels by precipitation and hydrolysis of crude phytate. These molecules have structural similarities to glucose and are involved in cellular signaling. It is considered a pseudovitamin as it is a molecule that does not qualify to be an essential vitamin because even though its presence is vital in the body, a deficiency in this molecule does not translate into disease conditions. Inositol can be found as an ingredient of OTC products by Health Canada but all current product whose main ingredient is inositol are discontinued. By the FDA, inositol is considered in the list of specific substances affirmed as generally recognized as safe (GRAS). Myo-inositol is an inositol having myo- configuration. It has a role as a member of compatible osmolytes, a nutrient, an EC 3.1.4.11 (phosphoinositide phospholipase C) inhibitor, a human metabolite, a Daphnia magna metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.
