| The occurrence of proteocephalid cestodes in tucunaré Cichla sp., captured monthly, between August 2000 and August 2001, in Paraná River, Presidente Epitácio, SP, was evaluated. From 128 specimens, 71 (55.6%) were parasitized by Proteocephalus macrophallus (Diesing, 1850) and/or P. microscopicus (Woodland, 1935). Total mean abundance and intensity were 157.08 and 223.41, respectively. The highest prevalence (90%) mean abundance (1,122.4) and intensity indexes (1,247.11) occurred in February 2001, while in September 2000 there were no observed animals infected by cestodes. No relationship between the sex of the host and parasitological indexes was found. |

| Multiple cell membrane alterations have been reported to be the cause of various forms of hypertension. The present study focuses on the lipid portion of the membranes, characterizing the microviscosity of membranes reconstituted with lipids extracted from the aorta and mesenteric arteries of spontaneously hypertensive (SHR) and normotensive control rat strains (WKY and NWR). Membrane-incorporated phospholipid spin labels were used to monitor the bilayer structure at different depths. The packing of lipids extracted from both aorta and mesenteric arteries of normotensive and hypertensive rats was similar. Lipid extract analysis showed similar phospholipid composition for all membranes. However, cholesterol content was lower in SHR arteries than in... |
