Turkish Journal of Veterinary & Animal Sciences
Despite the increasingly obvious sex differences, male animals are still predominantly used to study stress and related disorders. The aim of this study was to evaluate the effects of repeated noise stress in female and male mice. In the experiment, 12 male and 12 and female SPF/VAF 6-week-old Crl:CD1(lcr) mice were used. After 5 days of acclimatization all animals were placed in the open-field for three consecutive days where each mouse spent 10 min daily without any noise treatment in order to get used to the circumstances of the test. On day 9 to record baseline behaviour the animals were …

Turkish Journal of Veterinary & Animal Sciences
In this study, production performance, stress, and immunity levels of native Turkish and imported commercial laying hens were investigated in two different cage densities. In the trial, a total of 06 groups were formed by using two different cage densities (312.50 and 468.75 cm$^{2}$/hen) on each of 03 different laying hen hybrids of Isa Brown (IB), Atak-S (A-S) and Novogen White (NW). The trial was carried out with 09 replicates in each group having 10 birds per replicate making 540 birds in total. Water and feed were provided as ad libitum. It was found that the native hybrid showed lower …

The aim of this study was to evaluate the saliva cortisol levelsof recreational horses dependent on the type of horse activity. A total of 68 horses were included in the experiment and divided into groups according to recreational activity, type of horse, age, term of saliva collection, and sex. Saliva samples were obtained from each horse at 3 measurement points: in the morning (6 a.m.), in the evening (6 p.m.), and immediately after work. The overall analysis shows that the term of sample collection, recreational activity, and age influence cortisol concentration. The diurnal concentration of saliva cortisol does not differ …

Background/aim: Vitiligo is a depigmentation disorder that leads to serious psychological burden in patients, who are frequently reported to have depression and anxiety. The aim of this study was to investigate the association between stress-related hormone levels and psychological stress in vitiligo. Materials and methods: In this study46 vitiligo patients and 46 controls were enrolled; their cortisol, dehydroepiandrosterone sulfate (DHEAS),and cortisol/DHEAS levels were measured. Psychological burden was assessed by the Beck Depression Inventory and Perceived Stress Scale. Results: Patients and controls did not differ in terms of cortisol, DHEAS, or cortisol/DHEAS. Patients had higher perceived stress than controls but did …

Background/aim: The basolateral amygdala (BLA) modulates memory for emotional events and is involved in both stress and memory. This study investigated different durations of stress and the role of BLA on serum corticosterone level and spatial and cognitive memory. Materials and methods: Different durations of stress (acute, mid, and chronic stress), with and without BLA lesion were induced in rats by 6 h/day restraint stress for 1, 7, and 21 days. Memory functions were evaluated by novel object recognition (NOR) and object location test (OLT). Results: The OLT findings showed locomotor activity and spatial memory slightly decreased with different durations …

To compare the behavioural and neurobiological consequences of chronic headache and chronic mild stress (CMS) in rats. Materials and methods: Forty-eight male Wistar rats were divided into 4 groups: 1) control group, 2) chronic headache group, 3) CMS group, and 4) sham group. Their behaviour prior to (D0) and after (D14) chronic stress was analysed. Afterwards, they were exposed to the Elevated Plus Maze (EPM) in order to evaluate anxiety-like behaviour and the Forced Swim Test (FST) for observation of depressive-like behaviour. Ultrasonic vocalisations (USVs) were recorded by a USV detector system at D0 and D14 and during the FST. …

The Effect Of Stocking Density On Stress Reaction In Broiler Chickens During Summer, Mehmet Kenan Türkyilmaz
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to investigate the effect of stocking density on the heterophil to lymphocyte ratio (H:L), blood corticosterone concentration, immune response, and some performance parameters in broilers during summer. In all, 300 1-day-old commercial broiler chicks (Ross 308) were housed at densities of 15, 20, and 25 birds/m^2, with 2 replicates of each. H:L ratio and blood corticosterone concentration were used to measure the level of stress in the birds. Newcastle disease (ND) antibody titers were also analyzed to determine the level of immune response with a commercial ELISA kit. Mean H:L ratio, corticosterone concentration, and …

Differences in the protein and plasmid content of 2 Lactococcus lactis strains, L. lactis subsp. lactis LL52 and L. lactis subsp. cremoris LC79, under the stresses of high and low temperature, osmotic shock, and low pH were determined. We identified 3 new proteins with molecular masses of 16.0, 29.4, and 45.0 kDa as high temperature stress response specific in strain LL52. High temperature stress did not cause any changes in the protein content of strain LC79. Proteins that were specific for salt stress and low pH stress responses ranged between 16.0 and 40.5 kDa, and 24.8 and 107.5 kDa, respectively, …

The central nervous system may modulate many aspects of inflammation through alterations of the autonomic nervous system and/or the hypothalamo-pituitary-adrenal (HPA) axis. The aim of present study was to examine the impact of controllable acute stress on the course of experimental colitis and to elucidate the roles of serotonin (5-HT) and corticotropin-releasing factor (CRF) in the central modulation of the stress. In the stress group, acute electric shock (AES; 0.3-0.6 mA) was applied, while in the central agonist group, rats were injected with central 5-HT agonist (400 µg/kg). In the antagonist groups, 10 min before the application of AES or …
