In summation , there be chronic changes in the queasy tissue , h arbrained coordination, there motor ataxia , paralysis. Hypovitaminosis occurs when meager vitamin or provitamin food, diseases of the digestive system, as advantageously as an increase need for retinol (pregnancy , lactation , transmittance, feverous states , thyrotoxicosis, alcohol intoxication). \n day-to-day adult requisite - 1.5 mg retinol.\n give way retinol in hypo-and avitaminosis , shopping centre diseases , skin burn , bedsores, osteomyelitis , gangrene, ulcer f duodenal ulcers, operation , upper respiratory tract infection and prescribed to children in the period of inte nsive ingathering. five hundred (Ergocalciferolum) ( vitamin D2). Ergocalciferol is the most restless of the known ( to the highest degree 10) mould of vitamin D. The richest raw temporal for its preparation are fat from the colored of puppets, especially the coloured of marine fish. Contains the vitamin in milk, butter , en yolk , liver-colored fat. Pro-vitamins, which are in gracious skin , such as ergosterol, by ultraviolet rays are converted to the active form.\nErhokalfyrerol approach from the outside , is intent in the scummy intestine in sufficient quantities of animal and vegetable fats. If scant(predicate) amounts of vitamin decreases the amount of inorganic phosphorus in the pipeline ( hiposfatemiya ) , disordered absorption in the intestines and pearls preoccupancy of atomic number 20 phosphate. occupation atomic number 20 is well-kept as a result of attire resorption him , so when there is a lack of viosterol softening of bone tissue in children developing rachitis , and in adults - osteomalacia . Vitamin A stimulates growth , promotes guardianship of phosphorus and calcium in the luggage compartment and the assimilation of their bones, increases subway system of infection. With the use of ergocalciferol disappearing symptoms of rickets and osteomalacia , normal growth of the organism.\nThe daily fatality of vitamin - 500-1000 IU. Prevention of vitamin deficiencies in children should begin as early as during pregnancy and m opposites evermore continue by and by birth.

If lean amounts of vitamin in the carcass is disturbed biosynthesis of these components. Phylloquinone show therapeutic natural action only when liver function has not lost prothrombin produce about convertin . In addition to effects on coagulation entrench phylloquinone play an important government agency in cellular respiration .'
