A total of 90 cows from three commercial farms were used to evaluate the relationship between subclinical mastitis and clinical mastitis and thermal nociceptive threshold. Milk strips from all udder quarters were tested for clinical mastitis with visual inspection of milk and udder alterations and for subclinical mastitis using California Mastitis Test. Milk yield was recorded, milk was sampled...
The IL-1-related molecules, IL-1 and IL-18, can promote Th2 cytokine production by IgE/antigen-Fc RI-stimulated mouse mast cells. Another IL-1-related molecule, IL-33, was identified recently as a ligand for T1/ST2. Although mouse mast cells constitutively express ST2, the effects of IL-33 on mast cell function are poorly understood. We found that IL-33, but not IL-1 or IL-18, induced IL-13 and...
background: granuloca cells have a key role during estroeidogenesis. objectives: the purpose of this study was to determine the effect of number of culture medium granulosa cells on estradiol concentrations and mrna codding estrogenic and progestagenic enzyme. methods: briefly, follicles between 2 and 5 mm diameter were dissected from the ovaries of adult cows and were collected by rinsing the ...
BACKGROUND The glycoprotein CD30 is expressed and released by T lymphocytes that secrete type 2 helper cytokines of (T(H)2). These molecules play a role in the pathogenesis of allergic diseases. Venom immunotherapy has proven to be very effective in hymenoptera venom allergy through a shift in cytokine production from T(H)2-type cytokines to T(H)1-type cytokines. OBJECTIVE To evaluate the rel...
