Some aspects of nutrition and the kidney

摘要: T HE kidneys, particularly the proximal tubules of nephrons, are guardians nutritional wealth body. Each day, for example, nearly 2 kg. ascorbic acid filtered through walls glomerular tuft into renal tubules, and all but a few milligrams returned to bloodstream. The excretion in urine is determined by plasma level, rate filtration, maximum tubular reabsorption [I]; these functions, latter crucial preventing urinary wastage vitamin [Z]. extraordinary efficiency defending body against loss water-soluble vitamins, glucose, amino acids other nutrients more than matched lower reaches nephron which act conserve water electrolytes. Even chronic disease when large amounts dilute passed each there little or no excessive acid, conditioned deficiencies vitamins extremely uncommon complications failure. culty dietary manipulations. Nocturia, hematuria, calculi abnormalities have developed as result inadequate food intake. Thus far, K, A, alpha-tocopherol, linoleic choline, potassium, magnesium chloride been shown affect kidneys animals-usually [3]. pathologic changes not always clearcut, perhaps due present-day difficulties interpreting structural cells tinctorial technics.
