Chitotriosidase (ChT), a protein produced by activated macrophages, belongs to the chitinases, a group of enzymes able to hydrolyze chitin, a structural component of fungi and nematodes. A codominant inherited deficiency in ChT activity is frequently reported in plasma of Caucasian subjects, whereas in the African population this deficiency is rare. This study compares ChT activity in colostrum...

Iyengar, L., and Selvaraj, R. J. (1972). Archives of Disease in Childhood, 47, 411. Intestinal absorption of immunoglobulins by newborn infants. Intestinal absorption in newbom infants of immunoglobulins present in colostrum was studied by measuring the concentrations of inmunoglobulins IgA, IgG, and IgM in cord blood and following the changes in the serum of the infant on the 5th day after bir...

Oligomeric, J-chain-containing immunoglobulins were observed to be transferred selectively from serum into colostrum. These studies suggest that, in the case of the mammary gland secretion, a significant role for extraglandular synthesis of IgA merits consideration. Thus, for example, colostrum may contain antibodies synthesized locally as well as antibodies synthesized in the much larger lymph...

A short review is given on physical, chemical, biochemical, physiological, and functional properties of sow colostrum trypsin inhibitor. Special interest is concentrated on the physiological variations in colostrum and milk, and in serum and urine from suckling piglets. Possible significance of the inhibitor in relation to pathology is suggested.

Pre-colostrum and colostrum from goats cause a marked inhibition of the binding of 125I-labelled epidermal growth factor (125I-EGF) to Swiss 3T3 cells. The ability of these secretions to inhibit 125I-EGF binding is closely correlated with the ability to stimulate DNA synthesis in quiescent 3T3 cell cultures, suggesting that goat mammary secretions may contain an EGF-related mitogen. However, th...

Preterm birth and formula feeding predispose to small intestinal dysfunction, which may lead to necrotizing enterocolitis (NEC). In piglets, we tested whether the physiological and environmental transitions occurring at birth affect the response of the immature intestine to enteral feeding. Pig fetuses (106 days gestation, term = 115 days) were prepared with esophageal feeding tubes and fed eit...

INTRODUCTION Deep wounds are extending deeper, across deep fascia into muscles or deeper structures. Understanding of nutrition, immunology, psychological issues, the physiology and the metabolic interactions require for optimal treatment of deep wounds. Wound dressing plays one of the important roles in wound healing. Newer type of wound dressings - Biological dressings like colostrum powder, ...

Human milk is the main source of nutrients for a child during the first months of life. Alkaline phosphatase (EC 3.1.3.1) is a very important enzyme in clinical chemistry because of its activity in various tissues and biological fluids, being an indicator of physiological or diseased states. Milk contains several phosphatases, the principal ones being alkaline and acid phosphomonoesterases whic...

Male Sprague-Dawley rats were assigned to one of three dietary groups [standard diet (Cont; n = 8), standard diet plus bovine colostrum powder (BColost 1.7 g/kg; n = 8), or goat milk powder (GMilk 1.7 g/kg; n = 8)] to determine the ability of these supplements to reduce gastrointestinal hyperpermeability induced by heat. Raising core body temperature of rats to 41.5 degrees C increased transfer...
