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)
1. IRREGULAR COMPUTATION Modern science and engineering disciplines make extensive use of computer simulations. As these simulations increase in size and detail, the computational costs of naive algorithms can easily become prohibitive. Fortunately, sophisticated modeling techniques have been developed in many areas that that vary model resolution as needed(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)
The antimalarial activity of a series of synthetic 1,2,4-trioxanes is correlated with molecular structure by using a pharmacophore search method (CATALYST). The technique is shown to have predictive accuracy and confirms that docking between an active trioxane and the receptor, heme, is the crucial step for drug action.
