The regulation pattern of important enzymes in placental steroidogenesis and prostaglandin production in ewes with pregnancy toxemia is reviewed. The alterations of gene expressions after the administration of aglepristone (AG) and dexamethasone (DEX) are also discussed. Four healthy (CG) and 22 ewes with experimental pregnancy toxemia were included in the study. Ewes with pregnancy toxemia of group AG (n9) and group DEX (n9) were injected twice with 10 mg/kg of aglepristone and once with 5 ml dexamethasone respectively to induce parturition on 141 & PLUSMN;1,3 day of gestation; whereas health ...Более
The immune system of the cow is kept strong to protect the cows from mastitis, which causes economic losses for dairy cattle herds. Cellular immunity, especially, plays an important role as a first-line defense system. In the case of inflammation, cytokines play a decisive role in monitoring this process. In this study, the relationship between somatic cell count (SCC) and cytokine (tumor necrosis factor alpha, interferon gamma, and interleukins TNF-alpha, IFN-gamma,IL-2, -4, -5, and -10, respectively) concentrations in milk were determined. It was decided to support the humoral and cellular a ...Более
