Introduction L- in a combination

Introduction L- in a combination to a dofa-decarboxylase inhibitor () causes decarboxylation inhibition on peripheries and raised absorption L- . Long suppression of secretion of Prolactinum under the influence of a combination of these agents at healthy faces specifies on mediated through braking action L-. At patients with tumours the braking effect of these bonds is considerably weakened, that testifies to disturbance of robaxin 750 central effect L- [202] ( 7-16). The first data received in this direction, specify, however, that at patients with idiopathic Prolactinum reactions do not differ from those at patients with tumours. Antagonist 2- of Histaminum Cimetidinum enlarges at healthy faces Prolactinum secretion, operating through [87, 88]. Available not numerous data testify that patients with tumours do not react to Cimetidinum [88]. Data are published that (the inhibitor of return capture of Dofaminum ) brakes secretion of Prolactinum at healthy women and at postnatal , but only at a small number of patients with idiopathic or tumours [204, 204b]. The further experience of application of this agent before it will be possible to define degree of its utility for diagnostics tumours before occurrence of radiological changes is necessary. The differential diagnosis tumours are present, possibly, at the majority of patients with chronic rising of level of Prolactinum at which it does not find other explanations.
The indisputable diagnosis a tumour demands revealing not only , but also tumour signs, and the last become perceptible at patients with excessive rising of level of Prolactinum more often. At patients at whom Prolactinum level in blood exceeds 200 ng/ml, this diagnosis will be almost for certain correct even in the absence of changes on tomograms, and the dynamic assays referred on definition of secretion of Prolactinum, in such cases, as a rule, will yield pathological results. At patients at whom Prolactinum level in blood more low 200 ng/ml, is enlarged necessity of detection changes for decision-making concerning treatment. In the literature often use terms "microadenoma" and "macroadenoma" in relation to to tumours. In a general sense they reflect a clinical estimation of the sizes the tumours, based on data, and by that ease of statement of the diagnosis. Unfortunately, these terms are inexact, are applied by different authors to a designation of different concepts, and their sense varies as newer and thin techniques allow to find out the lesser sites of erosion or deformation of a Turkish saddle. It is necessary to realise that these terms are applied to a designation of different stages of the same process. other reasons buy skelaxin of rising of level of a hormone (tab. 7 10). At careful interrogation of the patient in the anamnesis it is possible to find out reception of the preparations, capable to cause . The substances influencing on central the regulation concern these preparations, or agents first of all. From such substances now psychotropic antagonists receptors (, , ) and more often apply antidepressants, antihypertensives (a-Methyldopa, Reserpinum), antihistamine () and antiemetic (Metoclopramidum, a prochlorperazine), and also peroral contraceptives. A galactorrhea observed and at the narcomaniacs using heroin; it can appear at stimulation receptors in . , caused by reduction of brake influences by Prolactinum secretion, can be result and primary changes in , leading to integrity disturbance gipotalamo-gipofizarnoj axes. and a galactorrhea are observed sometimes owing to hypothalamus damages at a sarcoidosis. These symptoms usually give in to treatment by resolvents. Are often accompanied disturbances, such, as an eosinophilic granuloma. In such cases other signs of dysfunction of a hypothalamus, in particular which seldom meets at small tumours of a pituitary body are usually taped also. To owing to a trauma of a leg of a pituitary body can result the damages of a skull bound to fractures of the basic bone or getting wounds. Like it, along with hypopituitarism signs can cause tumours (meningiomas, an optic nerve, a cranyopharyngioma) or the tumours formed in a hypothalamus (ependymoma). Morbidity of mammary glands and sometimes galactorrhea is often found out in patients with a hypothyrosis. Though usually Prolactinum level is in norm limits, it can and raise. At a long hypothyrosis the augmentation of a pituitary body wrongly diagnosed as a tumour of this organ can develop. Unlike patients with tumours at a hypothyrosis Prolactinum reaction on is raised. At 60-70 of patients with chronic insufficiency of function of kidneys Prolactinum level raises, reaching 150 ng/ml. Prolactinum reaction on is broken, but unlike that observe at pituitary body tumours, introduction and
