How does fingernail around desquamate return a responsibility?

Insufficient intake, such as proper nutrition of pregnant mother, appropriate vitamin C reserve at birth, cord blood plasma vitamin C content is 2-4 times higher than maternal plasma, so the incidence of infants under 3 months is less. But if the pregnant mother's diet lacks vitamin C, the newborn may also suffer from scurvy. Normal human milk contains about 40-70 mg / L vitamin C (4-7 mg / dl), which can meet the needs of ordinary infants.

When the metabolic rate increases, the requirement of vitamin C increases. When the growth is active, the content of vitamin C in the body decreases sharply. The growth and development of premature infants are faster, and the requirement of vitamin C is relatively larger than that of normal infants, so it should be supplemented more.

Other factors such as long-term intake of large amounts of vitamin C, its catabolism and renal excretion increase to reduce the concentration of plasma vitamin C. If a large amount of vitamin C is stopped suddenly, scurvy may occur. If a large amount of vitamin C is used for a long time during pregnancy, the newborn may still suffer from scurvy even if they take the normal amount of vitamin C every day after birth.
