Our previous investigations have shown that the opioid peptide methionine-enkephalin (Met-Enk) modulates in vivo a variety of humoral and cell-mediated immune performances. In this study, rats bearing polyethylene cannulae permanently inserted into the lateral ventricles of the brain were used. Experimental allergic encephalomyelitis (EAE) was induced with(More)
Exogenous opioid peptides, and enkephalins in particular, modulate a variety of immune performances in vivo and in vitro. In this study, the immunomodulatory role of endogenous opioids was investigated by means of central and peripheral administration of four peptidase inhibitors in the rat. Animals sensitized with sheep red blood cells (SRBC) were daily(More)
To evaluate the immunomodulating activity of methionine-enkephalin (Met-Enk) and leucine-enkephalin (Leu-Enk) in the development of experimental allergic encephalomyelitis (EAE), two strains of rats, one highly susceptible to EAE (Lewis rats) and the other relatively resistant to the disease (Wistar rats) were used. The animals were given daily injections(More)
Magnetic fields (MF) can influence biological systems in a wide range of animal species and humans. We report here on the influence of static MF, locally applied to the brain area, on immune system performances in the rat. In the first series of experiments two AKMA micromagnets (M) with the influx density of 600 Gauss were bilaterally implanted (with "N"(More)
INTRODUCTION Lung cancer is the leading cause of death from malignancy in Serbia. OBJECTIVE This is a retrospective analysis of lung cancer epidemiological changes regarding to its histological type and patients' age of both genders. Data were based on surgically treated lung cancer patients from 1985 to 2005. METHODS Data were collected from 972(More)
There is a large body of evidence for the role of thymosin peptides in immunogenesis and immunity. In this paper we report on the influence of prothymosin alpha 1 (ProT-alpha 1), a hormone-like peptide derived from the calf thymus, on humoral and cellular immune reactions in the rat. Young adults received intraperitoneal injections of ProT-alpha 1 in the(More)
