Stress is a biological response in the form of physiological, biochemical, hematological, and behavioral changes to internal or external stimuli that threaten the homeostasis of living beings. Effects that activate the defense system in living things are defined as stressors, and it is possible to talk about many different stress factors. Factors that cause stress can be divided into environmental, physical, social or emotional. Stress reactions, which begin with the effect of the stressor, vary according to the duration and severity of exposure to stress. In animal welfare, stress has many negative effects on organism. These negative effects may cause many problems and, shape future by adding problems such as stress and chain links in animals. Just as well-being is for humans, well-being is very important for animals. To determination of glucocorticoids or metabolites in the bloodstream of an organism under stress, noninvasive methods that provide reliable stress measurement without interfering with the organism have recently become increasingly popular. In this review article study, nineteen articles from various parts of the world were examined. In this review, measures of stress by non-invasive methods by looking at GlucoCorticoid Metabolites (GCM) and the latest developments in this field are discussed. In this review article study, nineteen articles from various parts of the world were examined. As a result of the articles reviewed, non-invasive methods for measuring stress may aid and improve our understanding of stress biology and animal welfare. Applying this method to many animal species and biological materials will provide accurate results and support animal welfare.

Salivary cortisone strongly correlates with serum cortisol, and since it is less invasive to measure salivary cortisone than serum cortisol and easier than to measure cortisol in saliva, as its concentrations are much lower, we wanted to compare salivary cortisone and cortisol levels as markers of noise-induced stress reaction. The study included 104 participants aged 19–30 years, 50 of whom were exposed to occupational noise ≥85 dB(A) and 54 non-exposed, control students. All participants took samples of their saliva with Salivette® Cortisol synthetic swabs on three consecutive working days first thing in the morning. Salivary cortisone and cortisol levels were determined with high-performance liquid chromatography. In addition, they completed a 10-item Perceived Stress Scale (PSS-10) questionnaire, and occupationally noise-exposed participants also completed the Health and Safety Executive (HSE) questionnaire on occupational psychosocial risks. The exposed participants had significantly higher cortisone (P

OBJECTIVE: Cortisol is a glucocorticoid and can be used as a stress mediator in association with adrenal insufficiency. A diagnosis of adrenal insufficiency is made when the episodically released cortisol levels are below 3 mcg/dl by making a single measurement at any time of the day. We aimed to determine the presence of underlying adrenal insufficiency by measuring cortisol levels in patients brought to the emergency room by the hospital code blue team that firstly performed their critical care, who fainted whilst giving blood samples in the blood collection unit. MATERIAL AND METHODS: Observational, prospective study; It consists of 28 patients brought to emergency department by Code Blue Team between 2017 and 2020. After physical examination and electrocardiogram(ECG) evaluation, samples were taken for complete blood count, biochemical parameters, venous blood gas, cardiac biomarkers and cortisol measurement. Obtained results were analyzed with SPSS 22. RESULTS: The lowest cortisol level was 9 mcg/dL, and the highest cortisol level was 40,4 mcg/dL. Cortisol levels were higher in women than men. But T-test analysis revealed that gender is not a determining factor in cortisol levels (p=0,26). The correlation between blood collection time and cortisol values was calculated close to zero (r2=0.09). The patient diagnosed with adrenal insufficiency with a single measurement was not defined in the study population. CONCLUSIONS: Patients with acute adrenal insufficiency may come to the emergency department with orthostatic hypotension, agitation, syncope, abdominal pain and fever, and may result in death if left untreated (1). Although emotional stress is 20% among the precipitating factors of adrenal crisis, no significant relationship was found between stress and cortisol in our study (2). The limitations of our study are that it can only be carried out during working hours, and advanced diagnostic tests can not be performed in the emergency room.

Amaç: Çalışmada esmololün intraoperatif anestezik- postoperatif analjezik gereksinimi, postoperatif kortizol ve prolaktin düzeylerine etkisini araştırmayı amaçladık. Gereç ve Yöntem: Çalışmaya 60 hasta dahil edilmiştir. Çalışma grupları şu şekilde dizayn edildi; 1: Esmolol infüzyonuna propofol ve remifentanil eklendi, 2: Sadece propofol ve remifentanil, 3: Esmolol infüzyonuna desfluran ve remifentanil eklendi, 4: Sadece desfluran ve remifentanil kullanıldı. Ameliyat öncesi ve sonrası kortizol ve prolaktin seviyeleri ölçüldü.Bulgular: Analjezik gereksinimi tüm gruplar içinde grup 1'de anlamlı olarak düşüktü ve grup 4 ile karşılaştırıldığında grup 3'te düşük bulundu. Kalp hızı esmolol gruplarında (grup 1 ve 3) kontrol gruplarına göre anlamlı olarak daha düşüktü. Prolaktin düzeyleri bütün gruplarda preoperatif değerlere göre postoperatif dönemde anlamlı yüksek bulundu. Ameliyat öncesi seviyelere ile karşılaştırıldığında postoperatif kortizol düzeylerinde grup 1de anlamlı bir azalma gözlendi. Sonuç: Laparoskopik kolesistektomi hastalarında anestezi yönetiminde adjuvan esmolol kullanımı herhangi bir hemodinamik instabiliteye neden olmadan anestezik - analjezik gereksinimini azaltıp postoperatif kortizol yanıtı baskılarken ameliyat sonrası prolaktin yanıtı üzerinde önemli bir etkisi yoktur.

Principles of personalising of application of herbs are developed. They are necessary for optimisation of operation of adaptive systems of an organism. Application of collectings of herbs promoted normalization of researched parameters. The collecting is constituted according to personalities of sportsmen. They were defined on parameters of vegetative balance and the contents of a hydrocortisone, an insulin and β-эндорфинов in a blood. Outcomes testify to efficiency of designed principles of personalising of application of herbs for recovering serviceability of sportsmen.
