1.1 Os níveis séricos de cálcio (Ca), fósforo (P), fosfatase alcalina (FA), paratormônio-intacto (PTH), pH e bicarbonato sérico (HCO3) ou reserva alcalina (CO2 total) devem ser determinados em todas as crianças e adolescentes nos estágios II a V da doença renal crônica (DRC). A frequência dessas determinações deve ser baseada na presença e na magnitude das alterações e na velocidade de progress...

Vitamin K, bone turnover, and bone mass in girls.

BACKGROUND Vitamin K has been suggested to have a role in bone metabolism, and low vitamin K intake has been related to low bone density and increased risk of osteoporotic fracture. OBJECTIVE The objective of this study was to determine whether phylloquinone (vitamin K(1)) intake and biochemical indicators of vitamin K status are related to bone mineral content (BMC) and markers of bone forma...

Difference in the metabolism of vitamin K between liver and bone in vitamin K-deficient rats.

The difference between vitamin K metabolism in the liver and that in the bone of vitamin K-deficient rats was examined. After 17 d administration of vitamin K-deficient food, vitamin K in the liver was almost depleted, and prothrombin time (PT) was prolonged. Serum total osteocalcin level was slightly decreased by vitamin K deficiency, whereas serum undercarboxylated osteocalcin level did not c...

Action of vitamin K on bone health

Objetives: Nowadays it is recognised that vitamin K plays an important role in bone health. It is necessary for the gamma-carboxylation of osteocalcin (the most important non-collagen protein in the bone), making the osteocalcin function. There are two important forms of vitamin K (vitamin K1 and vitamin K2), which come from different sources and have different biological activity. Epidemiologi...
