Long-lasting problem on the differentiation of adenohypophyseal cell, which prepares them for their specific tasks (somatotropic, lactotropic ect.), becomes elucidated after recognition of the differentiational effect of transcription factor Pit-1. Expression of that factor in somatotrops results in STH secretion, contrary to lactotrops producing prolactin. Subclinical hypothyreosis (increased TSH with normal T3 and T4) endangers vessel not because of hypercholesterolemia, but because of changes in the dynamics of the blood flow. The idea of cardiotropic effect of thyroidal hormones is supported by the finding that administration of trijodthyronine to children after the surgical correction of heart malformations (cardiopulmonary bypass) improves myocardial function--it elevates cardiac output and decreases requirements on the intensive care. Receptors for hormones in tissues are flexible, they can be "heterooligomers" for dopamine and somatostatin. Mutations of mineralocorticoid receptor may cause hypertension in pregnancy and progesterone receptors have several isoforms. Receptors can be also activated by short exposition to a hormone. Glucocorticoids have probably also membrane receptors. Diabetes mellitus "type I" needn't to be immunogenic and DM type II not only results from down-regulation of receptors and subsequent insulin resistance, but it can be also caused by defects in insulin secretion. Insulin has receptors in the brain and participates in the appetite regulation. The attempt to use "desensibilisation" by peroraly administered insulin in patients with immunogenic DM had no effect. Stress affects memory mechanisms, heavy emotional stress during gravidity can bring congenital malformations. The decrease of mental functions in aged women depends on the level of free estradiol (the fraction, which is not bound to plasma proteins). Activation of dopaminergic neurons can be achieved by neurotropic growth factors. Nesiritide is a recombinant brain natriuretic hormone successfully tested in heart failure. The role of leptin in the appetite regulation in man is still not clear, other signalling molecules may have also an effect, e.g., ghrelin, which primarily stimulates STH secretion and brings about weight gain. Sildenafil influences nitrergic neurons elsewhere than in penis, for example it has positive effects in patients with oesophageal achalasia.

Capsaicin, the pungent alkaloid of red pepper (Capsicum annuum) has been extensively studied for its biological effects which are of pharmacological relevance. These include: cardio protective influence, antilithogenic effect, antiinflammatory, and analgesia, thermogenic influence, and beneficial effects on gastrointestinal system. Therefore, capsaicinoids may have the potential clinical value for pain relief, cancer prevention and weight loss. It has been shown that capsaicinoids are potential agonists of capsaicin receptor (TRPV1). They could exert the effects not only through the receptor-dependent pathway but also through the receptor-independent one. The involvement of neuropeptide Substance P, serotonin, and somatostatin in the pharmacological actions of capsaicin has been extensively investigated. Topical application of capsaicin is proved to alleviate pain in arthritis, postoperative neuralgia, diabetic neuropathy, psoriasis, etc. Toxicological studies on capsaicin administered by different routes are documented. Capsaicin inhibits acid secretion, stimulates alkali and mucus secretion and particularly gastric mucosal blood flow which helps in prevention and healing of gastric ulcers. Antioxidant and antiinflammatory properties of capsaicin are established in a number of studies. Chemopreventive potential of capsaicin is evidenced in cell line studies. The health beneficial hypocholesterolemic influence of capsaicin besides being cardio protective has other implications, viz., prevention of cholesterol gallstones and protection of the structural integrity of erythrocytes under conditions of hypercholesterolemia. Beneficial influences of capsaicin on gastrointestinal system include digestive stimulant action and modulation of intestinal ultrastructure so as to enhance permeability to micronutrients.
