Abstract

Effects of steel and glass storage containers, duration of storage up to seven hours, and storage temperature on the concentration of humoral and cellular fac tors in 357 samples of human breastmilk were examined. Leukocytic functions were estimated by E-rosetting of sheep RBCs by T-lymphocytes and phagocytosis of S. cere visieae by phagocytes. Immunoglobulin (Ig) levels were studied by single radial immu nodiffusion technique (SRID).

Viability and cell counts reduced during the storage period, but were greater than 60 percent of baseline values. IgG, IgA, and IgM levels in milk did not show significant decline after storage (p>0.01). Milk stored in glass yielded a greater number of func tional cells after storage at 4°C. JHL12:31-35, 1996.
