Expression of steroidogenic enzymes in placentome of ewes with pregnancy toxemia after two parturition induction methods

Ali RIŞVANLI

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 ...More

Effects of FSH Administeredin Different Ways on Superovulation Response and Blood FSH Levels in Cows

Ayday CUNUŞOVA

This study aimed to compare three ways of FSH administration [single-dose subcutaneous (sc) using an adjuvant, single-dose epidural without an adjuvant and the conventional intramuscular (i.m) repeated decreasing doses] on blood FSH levels and superovulation response. Holstein cows (n:18) were divided into three groups for the superovulation procedure (n6). The animals in group (1) received intramuscular (im) decreasing doses of FSH (Stimufol, 500 mu g porcine FSH and 100 mu g porcine LH, Ulg FMV, Liege, Belgium) at 12-h intervals for 4 d. The animals in group (2) received FSH (500 mu g) into ...More

Investigation of cytokine levels in calves with naturally occurring sepsis

İsmail ŞEN

This study aimed to detect changes in clinical parameters, biochemical and serum cytokine levels in calves with naturally occurring sepsis. In the study, 34 calves diagnosed with sepsis according to clinical and laboratory results and 7 calves deemed to be healthy according to clinical and laboratory results were used. The blood sampling was performed by jugular venapuncture for hematological and biochemical analysis and the determination of cytokine levels. Significant changes were observed in the clinical parameters of calves with sepsis. Serum concentrations of IL-1 beta, IL-6, IL-10, TNF-a ...More

Udder defense system: Effect of milk somatic cell countlevel on Th1/Th2 cytokine balance

Ali RIŞVANLI

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 ...More

Clinical importance of lipid profile in neonatal calves with sepsis

Hasan GÜZELBEKTEŞ | İsmail ŞEN

In this study, it was aimed to determine of diagnostic importance of blood lipid levels in neonatal calves with sepsis. The study was carried out on a total of 70 calves, 60 with sepsis and 10 healthy calves. The calves with sepsis were included in the study, according to clinical and hematological findings. The blood samples were taken from the V. jugularis for hematological, lipid profile and biochemical analyzes after the routine clinical examinations of the calves. There were significantly (P < 0.05) decrease in body temperature, increase in respiration rate and capillary refill time in th ...More
