Polycystic kidney disease is an inherited multisystem disorder. It causes progressive loss of kidney function, flank pain, urinary tract infection, arterial hypertension and vascular abnormalities. Until the present time the treatment of polycystic kidney disease has been symptomatic. New approaches based on cell culture of cyst wall epithelia and on the discovery of polycystins 1 and 2 have lead to novel treatment protocols to attack the origin of the disease. These protocols involve vasopressin antagonists, rapamycin and somatostatin at the present time.

Hyponatremia is the most common electrolyte derangement occurring in hospitalized patients. The study presents a case of severe hyponatremia (range 93.2 mEq/l) in 67-year-old women presented weakness and neurological abnormalities. Laboratory tests showed additional electrolyte abnormalities such as hypokaliemia, hypomphosphatemia and hypomagnesemia. The cause of syndrome of inadequate antidiuretic hormone secretion (SIADH) in reported patient was lung carcinoma.

Hormones have an influence on many tissues and organs, including the cardio-vascular system (CVS). Depending on their activity on CVS, they can be divided into 4 groups: having hypertensive or hypotensive influence and chronotropic positive or negative action. Endocrine regulation in CVS may occur in many ways. Apart from hormones usually connected with CVS regulation, other more recently, discovered ones can act on it. A few of these act directly through specific receptors in heart or vessel wall cells, whereas some act indirectly - stimulating other neuroendocrine factors. Additionally, novel mechanisms of signal transduction have been discovered for steroid and thyroid hormones, which are independent of gene transcription regulation and are - known as "nongenomic". Hormones which increase blood pressure include: urotensin II, endothelins, angiotensin II, catecholamines, aldosterone, antidiuretic hormone, glucocorticosteroids, thyroid hormones, growth hormone and leptin. On the other hand, blood pressure can be decreased by: natriuretic peptides, the calcitonin gene-related peptide (CGRP) family, angiotensin 1-7, substance P, neurokinin A, ghrelin, Parathyroid hormone-related protein (PTHrP), oxytocin, and, sex hormones. Hormones which when appearing in excess increase the heart rate are: catecholamines, endothelins, glucocorticosteroids, thyroid hormones, leptin and PTHrP. Those which decrease the heart rate include: natriuretic peptides, substance P, neurokinin A, oxytocin, angiotensin 1-7. This paper describes the contemporary view of the functions of hormones which act on the vessel tree and heart. The particular effect of mediator depends on many circumstances i.e.: hormone concentration, receptor type. It may also undergo contraregulation. The majority of those hormones play an important role in the pathogenesis of CVS diseases', which can result in the development of new medicines.

At present, a constant progress in pathophysiology understanding and treatment of the chronic heart failure (CHF) is arising. The current CHF pharmacotherapy is complex, involving factors affecting the renin-angiotensin-aldosterone system (RAAS), beta-blockers, diuretics and vasodilatators. There are also significant efforts to introduce in CHF pharmacology novel therapeutic strategies, based on the other neurohormonal mechanisms activated in CHF. They include vasopressin receptor antagonists (VRA; vaptans), endothelin receptor antagonists (ERA; sentans), agents relating to the natriuretic peptides system (neutral endopeptidase inhibitors; NEPI and vasopeptidase inhibitors; VPI) and anticytokines agents (anti TNF-alpha immunoglobulin or TNF-alpha scavenger receptor; Etanercept). In this article we briefly describe the modem approach to CHF systemic treatment.

Diabetes insipidus is caused by insufficient secretion of vasopressin (ADH) or by an inability of the kidneys to respond to ADH. Pregnancy-associated DI occurs rarely but is connected with severe complications such as preeclampsia and hepatic function abnormalities. The following paper presents the case of a 36-year-old patient who had been diagnosed with diabetes insipidus in the 34th week of pregnancy.

Apelin is a recently discovered biologically active peptide present in several isoforms that are agonists for orphan receptor APJ. Apelin and APJ receptor were found in the central nervous system and in different peripheral tissues. In the cardiovascular system the peptide is present both in the heart and in the endothelium and smooth muscles cells of the vascular wall. Acting on cardiomyocytes apelin exerts positive inotropic effect, in the endothelium it releases nitric oxide, which mediates its vasodilatory action, while acting directly on smooth muscles cells it causes vasoconstriction. Apelin interacts with other compounds regulating blood pressure; for instance with angiotensin II, vasopressin, and with the sympathetic nervous system. Special attention is focused on the possibility of positive role of apelin in hypertension, initial stages of heart failure and ischaemic heart disease. Synthesis of apelin in adipocytes permits to include this peptide among adipokines. In the adipose tissue its production is increased in obesity and by insulin. It appears that apelin may play essential role in pathogenesis of insulin-resistant obesity. In patients with type 2 diabetes apelin improves glucose tolerance in initial stages of the illness. However, further experimental and clinical studies are required for full evaluation of significance of positive and negative aspects of the role of apelin in the cardiovascular and metabolic diseases.

Treatment with some drugs may induce hyponatraemia secondary to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). This is a report of a 52-year-old man who developed hyponatraemia after starting venlafaxine administration. Serum sodium level returned to the normal range following discontinuation of venlafaxine and application of SIADH--treatment within a few days. The study shows that routine assessment of blood electrolytes is needed in patients treated with drugs affecting vasopresin secretion.

Oxytocin and vasopressin, "peptides of love and fear", except for their classic role in control of labor and breastfeeding and blood pressure regulation, are also implicated in various processes like sexual behaviours, social recognition and stress response. These hormones seems to be essential for appropriate and beneficial social interactions, play a very important role in maternal care and closeness, promote general trust and cooperation and prolong social memory. They also play a very important role in modulating fear and anxiety response, especially by regulating the hypothalamic-pituitary-adrenal axis and amygdala activity by its projections to the brain stem and hypothalamic structures. Both hormones, particularly oxytocin, appears to be activating sexual behaviour or is responsible for increased sexual arousal. Evidence from clinical trials suggests their potential role in pathogenesis of schizophrenia, depression, autism and addiction together with possible therapeutic use in the above conditions. In schizophrenia, patients with higher peripheral oxytocin levels showed less severe positive, general and social symptoms and better prosocial behaviours. Literature suggests that exogenous oxytocin may be effective as an adjunctive therapy for that illness. Some data suggest that naturally occurring autoantibodies reacting with oxytocin and vasopressin are involved in depression, eating disorders and conduct disorder genesis.

Hyponatremia is a common electrolyte disorder occurring in patients with malignancy. Typically, it runs in the form of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Among malignant diseases it is often ascertained from small cell lung cancer. In the form of paraneoplastic syndrome it may precede clinical and radiological symptoms malignant disease. Hyponatremia requires special attention because of the neurological consequences and the risk of death. We present a case of a patient in whom the occurrence of hyponatremia preceded the appearance of clinical symptoms of lung cancer and has been the reason to start the diagnosis. The normalization of serum sodium was the first signal response to chemotherapy. In contrast, a statement confirmed the recurrence of hyponatremia progression of the disease in the form of metastases to the central nervous system. Speeches hyponatremia refractory symptomatic treatment should be a cause of further investigation into the neoplastic process. Recurrent hyponatremia during or after treatment may suggest its progression. Therefore, monitoring the sodium level is required not only during treatment, but also after the oncological treatment.

The aim of this review is to present the research results and draw new conclusions about the impact of alterations in the signal transmission through the G protein-coupled receptors (GPCRs) on the formation of diseases and drug therapy. GPCR family is the largest and the most diverse group of membrane receptors. They transmit signals into the cell by interaction with different ligands, which include, inter alia, hormones, neurotransmitters, and photons. GPCRs are responsible for the proper conduction of many physiological processes such as vision, intercellular communication, the neuronal transmission, hormonal signaling and are involved in many pathological processes. They are also point on the binding pathway of multiple drugs. They are targets of nearly one third of the drugs at the current pharmaceutical market. The genes encoding GPCRs represent about 4% of the human genome. Mutations that occur in them are associated with a broad spectrum of diseases of diverse etiology. As a mutations result, there is a change in receptor activity (GPCR become inactive, overactive, or constitutively active), in the process of ligand binding and signal transduction. Changes in the GPCRs functioning can cause diseases such as retinitis pigmentosa (rhodopsin mutations), nephrogenic diabetes insipidus (vasopressin receptor mutations), obesity (melanocortin receptor mutations). Many mutational changes in genes encoding GPCR can change drug therapy of already existed diseases: heart failure (adrenergic receptors), asthma (cysteinyl leukotriene receptors). Studies concerning the structure and function of genetically modified GPCRs allow to get know a variety of mechanisms of its action, which in turn can contribute to broaden the knowledge on the etiology and pharmacotherapy of many currently incurable diseases.
