Synonyms sex hormone, androgen, androstane, sex hormones Introduction Testosterone is a derivative of the sex hormone (androgen). Testosterone occurs in both sexes, but differs in concentration and effect. Tesotosterone is derived from testis (testicle) and steroid. The “inventor” of testosterone was Ernst Lageur, who was the first to extract bull testicles. In men, testosterone is … Testosterone
Side effects Among the most frequently observed side effects, especially in the form of overdose abuse are the following: Liver Diseases Kidney damage Cardiac arrhythmias Diseases of the cardiovascular system Arteriosclerosis Gynecomastia (butt formation in men) Steroid acne see: Acne Mental illnesses like depression Poorer memory performance Decrease in sperm count Reduction of the testicles … Side effects | Testosterone
Introduction Serotonin (5-hydroxytryptamine) is a tissue hormone and a neurotransmitter (transmitter of nerve cells). Definition Serotonin is a hormone and neurotransmitter, i.e. messenger substance of the nervous system. Its biochemical name is 5-hydroxy-tryptophan, which means that serotonin is a derivative, i.e. derivative of the amino acid tryptophan. The effect of a hormone and neurotransmitter always … Serotonin
Serotonin Syndrome Serotonin can be administered in small doses as a medication if someone is suffering from depression, for example. However, if the approved daily dose that can be taken is exceeded or if serotonin can no longer be broken down correctly or completely, it accumulates in the body and triggers the serotonin syndrome. Syndrome … Serotonin Syndrome | Serotonin
How can serotonin levels be measured? Serotonin levels cannot be measured directly. The detection in the blood is very imprecise and hardly allows any conclusions about diseases. Up to now, no method has been developed to determine the absolute serotonin content of the body. One of the reasons for this is that serotonin is practically … How can serotonin levels be measured? | Serotonin
Serotonin vs. dopamine Dopamine is another neurotransmitter of the brain. It is found in the basal ganglia and the limbic system, where it is involved in thought and perception processes and plays an important role in controlling movement.On the one hand, serotonin and dopamine are active as neurotransmitters, in different areas of the brain with … Serotonin vs. dopamine | Serotonin
Formation of mineral corticoids: Among the hormones synthesized in the zona glomerulosa are aldosterone and corticosterone. The output for the production of these hormones is cholesterol via pregnenolone and progesterone. Through further enzymatic changes (hydroxylation, oxidation) the mineral corticosteroids are finally produced. The corticosterone formed is converted to aldosterone. The receptor is located intracellularly, there … Mineral Corticoids
Formation of calcitonin: The hormone of the thyroid gland calcitonin consists of protein and is therefore a peptide hormone. In contrast to T3 – T4 hormone, this hormone is produced in the C-cells of the thyroid (parafollicular cells). The effect of this hormone unfolds on the bones, in which the bone-destroying cells (osteoclasts) are inhibited. … Calcitonin
Field of application Calcitonin is still used today in patients suffering from Paget’s disease (a disease of the skeletal system with increased and disorganized bone remodeling) who do not respond to other treatment options or for whom treatment alternatives are not suitable. One reason why other treatment would not be appropriate would be, for example, … Field of application | Calcitonin
Side effects The most frequent side effect of the administration of Calcitonin is a sudden reddening of the face. This is also known as “flush”. Other frequently occurring adverse drug reactions are a tingling sensation or a feeling of warmth in the extremities. Nausea, vomiting and diarrhoea can force a discontinuation of therapy. Hives (urticaria) … Side effects | Calcitonin
Formation of calcitriol: The steroid-like hormone calcitriol is formed from the precursor 7-dehydrocholesterol, which in turn is formed from cholesterol. The hormone passes through several stages in the course of its synthesis: First the skin under the influence of UV light, then the liver and finally the kidney. Calciol (cholecalciferol) is formed in the skin, … Calcitriol
Hormones produced in the kidney include Calcitriol and Erythropoietin This glycoprotein hormone as a hormone of the kidney is produced in the kidney and to a small extent in the liver and brain in about 90% of adults. In the kidney, cells of the blood vessels (capillaries, endothelial cells) are responsible for production. They begin … Kidney hormones
