Pituitary adenylate cyclase-activating polypeptide (PACAP) is a well-known neuropeptide, which also has vasomotor effects. However, little is known regarding its age-related and organ-specific vasomotor effects. We hypothesized that the vasomotor effects of PACAP depend on the tissue origin of the vessels and aging substantially modulates its actions. Thus,(More)
In this study, we hypothesized that aging alters angiotensin II (Ang II)-induced vasomotor responses and expression of vascular mRNA and protein angiotensin type 1 receptor (AT1R). Thus, carotid arteries were isolated from the following age groups of rats: 8 days, 2-9 months, 12-20 months, and 20-30 months, and their vasomotor responses were measured in a(More)
Daily body core temperature rhythm has been known to become blunted for several days following intra-abdominal implantation of biotelemetry transmitters in small rodents and about a week is required for re-establishment of stable body core temperature oscillation. In the present study carried out on mice it was found that a repetition of the same minor(More)
BACKGROUND Acetylsalicylic acid (ASA) plays an important role in the treatment and prevention of cardiovascular diseases. Metamizole (MET) is an analgesic and antipyretic medicine, it is not used as an antiplatelet drug. OBJECTIVES We aimed to examine the antiplatelet effect of MET and the possible interactions between the drugs. METHODS In our in vitro(More)
Authors carried out during one and a half year 135 anaesthesias with isoflurane. 104 of them was administered in closed, and 31 in semi-closed system. The results were compared with halothane and fentanyl anaesthesias. After brief review of the literature about isoflurane, authors evaluated their own experiences The most favourable result was the stability(More)
RATIONALE Nebivolol is known to have beta-1 blocker activity, but it was also suggested that it elicits relaxation of the peripheral arteries in part via release of nitric oxide (NO). However, the effect of nebivolol on the vasomotor tone of cerebral arteries is still unclear. OBJECTIVE To assess the effects of nebivolol on the diameter of isolated rat(More)
Vascular remodeling during chronic hypertension may impair the supply of tissues with oxygen, glucose and other compounds, potentially unleashing deleterious effects. In this study, we used Spontaneously Hypertensive Rats and normotensive Wistar-Kyoto rats with or without pharmacological inhibition of poly(ADP-ribose)polymerase-1 by an experimental compound(More)
An anaesthetic method without intubation has been used for the first time in Hungary in 107 laryngomicroscopic operations. The method includes: Vagolytic, analgetic, sedative, vasodilatator, coronary flow enhancing, antihypertensive and antitussive premedication. Administration of the sedative anaesthetic gamma-OH, void of respiratory depression, in doses(More)
Aging induces substantial morphological and functional changes in vessels. We hypothesized that due to morphological remodeling the total contractile forces of arteries increase, especially in older age as a function of age. Mean arterial blood pressure of rats and morphological and functional characteristics of isolated carotid arteries rats, from newborn(More)
