13. Avaliação da resposta inflamatória pulmonar e do transporte mucociliar em modelo de inflamação alérgica pulmonar: modulação pelo estresse induzido pela natação forçada / Evaluation of pulmonary inflammatory responses and mucociliary transport in a model of chronic allergic inflammation: modulation by stress induced by forced swimming
Background: It has increasing evidence linking the role of stress in the onset of asthma exacerbation and in the maintenance of asthmatic crises, as well as the importance of mucus production and the mucociliary clearance in the asthma physiopathology. Objectives: So, we consider relevant to evaluate in guinea pigs with pulmonary chronic allergic inflammatio

14. Expression profiles of metastasis-related genes in a cohort of childhood and adult adrenocortical tumors / Perfis de expressão de genes relacionados a metástases em uma coorte de pacientes adultos e pediátricos portadores de neoplasias do córtex da supra-renal
Adrenocortical carcinoma (ACC) is a rare neoplasm with a poor prognosis. Although molecular studies have uncovered many aspects of ACC tumorigenesis, little is known about molecular pathways involved in metastatic spread. The objective of our study is to analyze the expression profile of metastasis-related genes in a cohort of metastatic and nonmetastatic ad

15. Repercussões sistêmicas da orquiectomia bilateral, em ratos
This investigation belongs to a line of research, and its purpose was to evaluate the effects of hypogonadism secondary to orchiectomy on the organism of rats. 178 male Wistar rats were used. Of these, 54 were young (Y) and 124 were mature (M). These animals were divided into the following groups: Group 1 control, animals submitted only to incision and sutur

16. Expression of mdr isoforms in mice during estrous cycle and under hormone stimulation
The multidrug resistance (MDR) phenotype is associated with the expression of P-glycoprotein (Pgp), coded by the multigenic mdr family. Mice present the isoforms mdr1 and mdr3, which are responsible for multidrug resistance, and mdr2, that is involved in the transport of phospholipids. mdr1 expression has more recently been associated also with the secretion

17. Assessment of serum catecholamine concentrations in patients with pheochromocytoma undergoing videolaparoscopic adrenalectomy
INTRODUCTION: We analyzed the changes in serum catecholamine concentrations, i.e. adrenaline and noradrenaline, in response to surgical stress in patients with pheochromocytoma who undergone videolaparoscopic adrenalectomy. MATERIALS AND METHODS: Between January 1998 and March 2002, 11 patients underwent 12 videolaparoscopic adrenalectomies. In one case, the

18. Biodistribution studies of bee venom and spider toxin using radiotracers
The use of radiotracers allows the understanding of the bioavailability process, biodistribution, and kinetics of any molecule labelled with an isotope, which does not alter the molecule's biological properties. In this work, technetium-99m and iodine-125 were chosen as radiotracers for biodistribution studies in mice using bee (Apis mellifera) venom and a t

19. Expression of the DBA/2J Ren-2 gene in the adrenal gland of transgenic mice.
To characterize further the tissue-specific control of the mouse Ren-2 gene, and in particular its expression in the adrenal gland, we have introduced the DBA/2 Ren-2 gene into the genome of Ren-1c/Ren-1c mice. Here we report our observations on Ren-2 transgenic mice. Expression was found in the correct spectrum of tissues and included appropriate hormonal c

20. Secretion of catecholamines from adrenal gland by a single electrical shock: electronic depolarization of medullary cell membrane.
Transmural stimulation of the isolated adrenal gland of the rat and guinea pig results in secretion of catecholamine. The secretion is due to activation of cholinergic receptors of the adrenal medulla by acetylcholine released from splanchnic nerve terminals after transmural stimulation. Our aim was to see whether the same experimental technique could be use

21. The effect of changes in adrenal blood flow on adrenal cortical responses to adrenocorticotrophin in conscious calves.
1. The effect of varying adrenal blood flow on the rate at which it was estimated that adrenocorticotrophin (ACTH) was presented to the adrenal gland was related to right adrenal cortisol output in conscious calves fitted with 'adrenal clamps'. 2. Intra-aortic infusions of endothelin at either 15.0 or 7.5 pmol min-1 kg-1 produced a substantial fall in right

22. Atrial natriuretic factor receptors in rat kidney, adrenal gland, and brain: Autoradiographic localization and fluid balance dependent changes
Mammalian atria contain natriuretic peptides designated atrial natriuretic factors (ANF). Using in vitro autoradiography with 125I-labeled ANF, we have localized high-affinity (Kd = 150 pM) ANF binding sites to the glomeruli of the kidney, zona glomerulosa of the adrenal gland, and choroid plexus of the brain. The numbers of sites in both kidney and adrenal

23. Enkephalin- and somatostatin-like immunoreactivities in human adrenal medulla and pheochromocytoma.
By using the Coons indirect immunofluorescence technique, enkephalin-like immunoreactivity with a granular localization was observed in human adrenal medullary gland cells and pheochromocytomas. In two of the tumors and in a few adrenal gland cells, a somatostatin-like peptide could also be identified. Catecholamine cell types were visualized on adjacent sec

24. The role of the pituitary-adrenocortical axis in reflex responses of the adrenal medulla of the dog.
1. The release of catecholamines from the adrenal medulla, in response to carotid body hypoxia, may outlast the stimulus by more than 30 min. 2. After denervation of the adrenal gland the immediate release of catecholamines in response to carotid hypoxia is abolished, but the prolonged release remains. 3. The prolonged release of catecholamines is abolished
