Infant body detoxification mechanism, protection mechanism is poor, easy to cause the accumulation of a large number of chemical substances, the World Health Organization and countries have stipulated that in infant food shall not add food additives, children's food should also try to limit the addition of saccharin, coloring, essence and so on. Especially in the infant food less than 12 weeks of age, such as infant formula food, cereal products, etc. should be completely free of food additives. Classification of food additives: food additives can be divided into natural food additives and chemical synthetic food additives two categories. Natural food additives are derived from the metabolites of animals and plants or microorganisms. Chemical synthesis additives are prepared by chemical synthesis of chemical substances as raw materials. According to the purpose of use and the nature of the chemical substance, food additives can be divided into the following categories: (1) acid, base, salt; (2) loosening agent; (3) Antioxidants and synergists; (4) carrier solvent; (5) Food coloring; (6) emulsifier, stabilizer, thickening agent; (7) e

Structure and health hazards of silica Silicon dioxide (chemical formula: SiO2) is an acidic oxide, the corresponding hydrate is silicate (H2SiO3). It has been known since ancient times. Silica is most common in nature in quartz, as well as in a variety of organisms. In many parts of the world, silica is the main component of sand. Silica is one of the most complex and abundant families of materials, being both a variety of minerals and produced synthetically. Applications range from structural materials to microelectronics to ingredients used in the food industry. structure SiO2 crystal has a variety of crystal forms, its basic structural unit is tetrahedral, each Si around the combination of 4 O, Si in the center, O in the four top angles; The smallest ring has six silicon atoms and six oxygen atoms. Many of these tetrahedrons are connected by the O of the vertex Angle, each O is shared by two tetrahedrons, that is, each O is combined with two Si. In fact, SiO2 crystal is composed of Si and O in a ratio of 1:2 three-dimensional network structure crystal. Therefore, SiO2 is usually used to represent the composition of silica. SiO4 tetrahedrons are found not only in SiO2 crystals but also in all silicate ores and are the basic skeleton that makes up the colorful silicate world.

The difference between nimodil and felodipine Nimodidi and felodipine are both calcium channel blockers. Calcium channel blockers are widely used in the treatment of hypertension, angina pectoris, arrhythmia and other diseases due to their strong antihypertensive effect and good tolerance. However, there are many differences in pharmacological mechanisms and indications between nimodidi and felodipine. Different pharmacological mechanisms Nimodipine is a calcium channel blocker. The contraction process of smooth muscle cells depends on calcium ions, which enter these cells as slow ionic transmembrane currents during depolarization. Nimodipine inhibits calcium transfer into these cells, thereby inhibiting vascular smooth muscle contraction. Felodipine is a member of the dihydropyridine class of calcium channel antagonists (calcium channel blockers). The effect of felodipine on blood pressure is primarily a dose-dependent reduction in human peripheral vascular resistance with a modest increase in reflex heart rate. In addition to the mild diuretic effects found in several animals and humans, the effects of felodipine are mainly reflected in its effect on peripheral vascular resistance. Different indications Nimodipine can be used clinically for subarachnoid hemorrhage, ischemic cerebrovascular disease, migraine, senile brain dysfunction, mild to moderate hypertension, sudden deafness. Felodipine can be used clinically for hypertension and stable angina pectoris. Contraindications vary Nim horizon It is forbidden if you are allergi
