The present study was conducted in order to isolate and identify the phytochemical constituents responsible for analgesic effects shown by a methanolic extract obtained from Sebastiania schottiana roots. Conventional chromatographic procedures led to the isolation of moretenone, glutinol, beta-sitosterol and stigmasterol. The structural elucidation of these(More)
Peripheral blood (PBL) and synovial fluid lymphocytes (SFL) from 18 patients with definite rheumatoid arthritis (RA) and from one patient with Reiter's disease (RD) were examined for their capacity to absorb quantitatively interleukin-2 (IL-2) from a standardized, lectin-free IL-2 source. For comparison normal ConA blasts and PBL from various inflammatory(More)
Using lectin-free IL-2 as the only initial stimulus, bulk cultures and T-cell clones were established from synovial fluid (SFL) and peripheral blood lymphocytes (PBL) of a patient with rheumatoid arthritis (RA). The cloning efficiency of growing bulk cultures was 3%–4% as evaluated by Poisson statistics and was not enhanced by the addition of autologous(More)
Polybrominated diphenyl ethers (PBDEs) and the structurally similar chemicals polychlorinated biphenyls (PCBs) disrupt the function of multiple endocrine systems. PCBs and PBDEs disrupt the secretion of vasopressin (VP) from the hypothalamus during osmotic activation. Since the peripheral and central vasopressinergic axes are critical for osmotic and(More)
The central hypotensive agent, clonidine (30 microgram/kg i.v.) has been injected in normotensive rats anesthetized with various agents. This dose of clonidine elicits usually a biphasic blood pressure response, i.e. a transient increase due to peripheral vasoconstriction, followed by a long lasting decrease. This has been observed in the animals(More)
