We examined the influence of dietary fermentable protein (fCP) and fermentable carbohydrates (fCHO) on the colonic epithelial response to histamine in pigs. Thirty-two weaned piglets were fed 4 diets in a 2 × 2 factorial design with low fCP/low fCHO, low fCP/high fCHO, high fCP/low fCHO and high fCP/high fCHO. After 21-23 days, the pigs were killed and tissue from the proximal colon was stimula...
The biochemistry of human semen is poorly understood, and despite initial studies by Mann (1964) little is known about the metabolism of spermatozoa1 cells, and even less about the seminal plasma. We have attempted the simultaneous purification of fumarase, peroxidase, diamine oxidase and adenosine deaminase from human seminal plasma, and compared the properties of these enzymes with those from...
Changes in the contents of polyamines (PAs) in tobacco leaves (Nicotiana tabacum L. cv. Wisconsin 38) grown under 16 h photoperiod were correlated with arginine and ornithine decarboxylase (EC 4.1.1.19 and EC 4.1.1.17) and diamine oxidase (EC 1.4.3.6) activities. The maximum of free and soluble conjugated forms of PAs occurred 1-2 h after the middle of the light period and was followed by two d...
Putrescine is the major source of y-aminobutyric acid (GABA) in the rat adrenal gland. Diamine oxidase, and not monoamine oxidase, is essential for GABA formation from putrescine in the adrenal gland. Aminoguanidine, a diamine oxidase inhibitor, decreases the GABA concentration in the adrenal gland by more then 70 % after 4 h, and almost to zero in 24 h. Studies using [14C]putrescine confirm th...
