Ultrastructural alterations of intracellular stages and effects on blood forms of Trypanosoma cruzi induced in vivo by 2-amino-5-(1-methyil-5-nitro-2-imidazolyl)-1,3,4 - Thiadiazole

An electron microscopy study shows that the administration of a single dose (500 mg/kg, p.o.) of 2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1, 3, 4-thiadiazole induces in mice infected with Trypanosoma cruzi results in degenerative lesions of the intracellular stages. Ultrastructural alterations are detected as early as 6 hours after the drug administration and destruction of the parasites occurs within 18 - 36 hours. Trypomastigotes are cleared from the bloodstream 4 to 6 hours after treatment. The combined effect on both developmental stages is apparently responsible for the in vivo ejfects of this drug which is the most active drug ever tested in our laboratory in experimental Chagas' disease.

Effects of the α₂-adrenergic agonist clonidine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine in healthy volunteers.

The mechanism of action of 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) involves the carrier-mediated and potentially vesicular release of monoamines. We assessed the effects of the sympatholytic α₂-adrenergic receptor agonist clonidine (150 μg p.o.), which inhibits the neuronal vesicular release of norepinephrine, on the cardiovascular and psychotropic response to MDMA (125 mg p.o.) in 16 healthy subjects. The study used a randomized, double-blind, placebo-controlled crossover design with four experimental sessions. The administration of clonidine 1 h before MDMA reduced the MDMA-induced increases in plasma norepinephrine concentrations and blood pressure but only to the extent that clonidine lowered norepinephrine levels and blood pressure compared with placebo. Thus, no interaction was found between the cardiovascular effects of the two drugs. Clonidine did not affect the psychotropic effects or pharmacokinetics of MDMA. The lack of an interaction of the effects of clonidine and MDMA indicates that vesicular release of norepinephrine, which is inhibited by clonidine, does not critically contribute to the effects of MDMA in humans. Although clonidine may be used in the treatment of stimulant-induced hypertensive reactions, the present findings do not support a role for α₂-adrenergic receptor agonists in the prevention of psychostimulant dependence.

Implantación del distintivo de garantía de calidad ambiental en hoteles de 3*, 4* y 5* de Sitges

Este proyecto tiene como objetivo estudiar la viabilidad de la implantación del Distintivo de Garantía de Calidad Ambiental (DGQA) en los hoteles de 3*, 4* y 5* del municipio de Sitges, perteneciente a la comarca del Garraf. El criterio de selección se ha basado en el estado del hotel (abierto o cerrado) en que se encontraba en el momento del estudio. Para conocer la gestión ambiental de los establecimientos hoteleros se llevó a cabo la realización de unas encuestas elaboradas a partir de los criterios requeridos por el DGQA, tanto obligatorios como opcionales. Los resultados obtenidos muestran un elevado cumplimiento de la puntuación obligatoria, así como la totalidad de los criterios opcionales requeridos. No se han detectado diferencias significativas entre las tres categorías hoteleras. Sin embargo, sí que aparecen diferencias entre los ámbitos propuestos por el DGQA, destacando el elevado cumplimiento en integración paisajística, ruidos y vibraciones, y diseño de espacios exteriores. Por el contrario se observa una carencia relevante en los ámbitos de compras y residuos. Finalmente se han propuesto las acciones de mejora necesarias para dicha obtención, obteniendo así un presupuesto aproximado para la consecución del distintivo por cada uno de los hoteles.

Modification of oxidative status in Plasmodium berghei-infected erythrocytes by E-2-chloro-8-methyl-3-[(4'-methoxy-1'-indanoyl)-2'-methyliden]-quinoline compared to chloroquine

E-2-chloro-8-methyl-3-[(4'-methoxy-1'-indanoyl)-2'-methyliden]-quinoline (IQ) is a new quinoline derivative which has been reported as a haemoglobin degradation and ß-haematin formation inhibitor. The haemoglobin proteolysis induced by Plasmodium parasites represents a source of amino acids and haeme, leading to oxidative stress in infected cells. In this paper, we evaluated oxidative status in Plasmodium berghei-infected erythrocytes in the presence of IQ using chloroquine (CQ) as a control. After haemolysis, superoxide dismutase (SOD), catalase, glutathione cycle and NADPH + H+-dependent dehydrogenase enzyme activities were investigated. Lipid peroxidation was also assayed to evaluate lipid damage. The results showed that the overall activities of glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase were significantly diminished by IQ (by 53.5% and 100%, respectively). Glutathione peroxidase activity was also lowered (31%) in conjunction with a higher GSSG/GSH ratio. As a compensatory response, overall SOD activity increased and lipid peroxidation decreased, protecting the cells from the haemolysis caused by the infection. CQ shared most of the effects showed by IQ; however it was able to inhibit the activity of isocitrate dehydrogenase and glutathione-S-transferase. In conclusion, IQ could be a candidate for further studies in malaria research interfering with the oxidative status in Plasmodium berghei infection.
