Potential animal feed allergens.

The aim of this article is to present the interdisciplinary area that concerns both animal feed allergy and human food allergy. The following problems are presented: definition of animal feed allergy, mechanism of food/feed allergy, contemporary paradigm of immune response, nature of epitopes, neoallergens, nutrigenomics and animal holistic feeding. Finally, it is noted that the present view on food/fodder and nutrition of people and animals have more and more in common. Their common ground is the idea of nutritional genomics as an idea of individual nutrition, prevention and therapy.

[Content of micro- and macro-elements, lead and cadmium in albumins and globulins of fresh and stored, dried seeds of the Faba bean]. / Zawartosc mikro- i makroelementów, olowiu i kadmu w albuminach i globulinach swiezych oraz przechowywanych i suszonych nasion bobiku.

The content of micro/macroelements, lead and cadmium in Faba bean proteins from the seeds after their harvest and from the seeds stored (2 months, 6-8 degrees C) and dried (6h at 35 degrees C up to 15-15% moisture) was determined. Proteins were extracted with water (pH 8.0). Globulins were precipitated from water protein extract at pH 4.2. The microelements (Cu, Mn, Fe and Zn) content in albumins and globulins from the seeds after their harvest and from stored and dried seeds were as follows: 37.4 and 27.1; 46.7 and 35.8; 15.4 and 18.9; 179.2 and 229.7 micrograms/g (albumins) and 24.9 and 31.9; 20.0 and 28.1; 92.1 and 205.4; 68.7 and 102.9 micrograms/g (globulins). These findings indicate that Faba bean albumins and globulins form the labile and neutral nucleo-glycoprotein complexes with Cu, Mn, Fe and Zn. The process of storage and drying caused the migration of the micro and macroelements between albumins and globulins. Generally, one may say that Faba bean albumins and globulins are the source of the biologically active micro- and macroelements.

[Nucleic acid levels in milk and blood of healthy cows and those with mastitis]. / Zawartosc kwasów nukleinowych w mleku i krwi krów zdrowych i z zapaleniem wymienia.

Investigations were carried out in 30 ncb breed cows divided into two groups. First group was consisted with cows in good health. In second group there were cows ill with mastitis. Number of somatic cells in milk was evaluated by California Mastitis Test and nucleic acids content in milk and blood by spectrophotometric method. Nucleic acids content in group of healthy cows amounted 273 micrograms/100 ml in milk and 0.114 g/100 ml in blood. In this group correlation factor concerning nucleic acids content in milk and blood amounted r = +0.57. In group ill cows nucleic acids content in milk and blood amounted respectively 500 micrograms/100 ml and 0.140 g/100 ml, and value of correlation factor r = -0.09 was noted. Differences in nucleic acids content in milk and blood between both groups healthy and ill cows correspond to values 227 micrograms/100 ml and 0.026 g/100 ml and were statistically significant by p less than 0.01. Above results allow to formulate the following conclusions: 1. Statistically high correlation between quality of somatic cells and nucleic acids content in milk exists--it is confirmation well known fact. 2. The rise of nucleic acids content in blood of cows can be an index of udder inflammation in cows.
