NON-PROTEIN NITROGENOUS CONSTITUENTS OF HUMAN MILK

Buffer Intensities of Milk and Milk Constituents

Titration data on milk have been published by Van Slyke and Baker (l), Buchanan and Peterson (2), Moser (3), and others. Titration curves of milk have been given by Clark (4) and by Moser (3). Buchanan and Peterson (2) have calculated the buffer efficiency of milk for a number of zones of the pH range. Clark (4, 5) has made several similar calculations and has outlined the difficulties to be av...

Procedures for the microestimation of nitrogenous phosphatide constituents.

This paper describes procedures for the separation and quantitative estimation in minute amounts of several nitrogenous substances normally encountered as constituents of phosphatides; viz., ethanolamine, choline, and serine. The work is based on techniques employing paper chromatography, previously applied to the investigation, in a qualitative fashion only, of tissue lipides (1) ; its princip...

Major constituents, leptin, and non-protein nitrogen compounds in mares' colostrum and milk.

Five Haflinger mares were hand-milked at 0 h (pre-suckle) and 6 h (postsuckle), 12, 24, 48, 72 and 96 h after parturition. Total solids, protein, fat, lactose, calculated gross energy content, leptin and non-protein nitrogen components (urea, alpha-amino nitrogen, creatinine and allantoin) were determined. The levels of the major constituents differed significantly in pre-suckle colostrum from ...

Immunomodulatory constituents of human breast milk and immunity from bronchiolitis

BACKGROUND The mother's immune status can be achieved by genetic and breastfeeding impact descendants of the immune system. The study aimed to determine whether a mother's immune status and breastfeeding practices were related to development of bronchiolitis in her infant. METHODS The frequency of T, B and natural kill (NK) cells in patients' blood and their mothers' breast milk was determine...
