Actions of bovine somatotropin on polymorphonuclear leukocytes and lymphocytes in cattle.
Objectives were to determine 1) in vitro effects of bST on function of polymorphonuclear leukocytes and lymphocytes and 2) in vivo effects of bST on leukocyte function of heifers fed to maintain medium or high growth rates. When administered in vitro, bST did not affect function of polymorphonuclear leukocytes. [Methyl-3H]thymidine incorporation by resting lymphocytes was stimulated by 1000 ng/...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولCentrifugal subfractionation of polymorphonuclear leukocytes, lymphocytes and erythrocytes.
By BERNARD W. AGRANOFF, BERT L. VALLEE AND DAVID F. WAUGH A METHOD HAS BEEN DESCRIBED’ by which leukocytes may be separated from erythrocytes. The technic takes advaustage of the difference its density betweems the two cell classes. Fmactionat.ioms is accomplished by sedimetstiusg the population of cells through two media, plasma and albumin, havimig a differential of density imstermediate hetw...
متن کاملPolymorphonuclear Leukocytes
Complete protection of Staphylococcus aureus Wood 46 from gentamicin bactericidal activity was documented for microorganisms located within polymorphonuclear leukocytes. The highest, still ineffective gentamicin concentration tested in the phagocytic assay was 80 times higher than the minimal concentration required to kill uningested organisms. Extracellular gentamicin activity was unaffected b...
متن کاملEffects of florfenicol, chloramphenicol, and thiamphenicol on phagocytosis, chemiluminescence, and morphology of bovine polymorphonuclear neutrophil leukocytes.
Florfenicol, chloramphenicol, and thiamphenicol were tested in vitro to determine their potential toxic effects on bovine neutrophils. Antibiotics were tested at 4000, 2000, and 10 micrograms/ml of incubation mixture. Percentage phagocytosis was determined by incubations with neutrophils isolated from milk of five cows and 32P-labeled Staphylococcus aureus and 5% skim milk. The effect of 4000 m...
