title: Role of prolactin in human milk composition and serum lipids studied during suppression of galactorrhea with bromocriptine.
abstract: Bromocriptine suppressed lactation by depressing the serum prolactin (PRL) level in 10 of 12 cases with profuse galactorrhea. The PRL level in galactorrhea milk was lower than in serum and was similar to that obtained in normal mature milk. However, significantly higher total solid, total ash, lipid and calcium levels, and reduced lactose and potassium levels were seen in galactorrhea specimens compared to mature milk. Although all the constituents decreased during treatment, the highly significant reduction in lipid and calcium levels shows the predominant effect of PRL on mammary synthesis and/or transport of these constituents. Fasting serum total lipids, total cholesterol and triglyceride levels were significantly higher in the galactorrhea group than in breast-feeding women with established lactation, suggesting that elevated serum PRL plays a role in lipid metabolism.
