“…It is well known that zinc, like copper, is another element that interferes with cellular adsorption when it depends on metallothionein (Lal et al , 1974; Ville, 1968), a metal‐fixing protein complex with SH − . SH − can fix copper and its formation can be induced by copper itself (Lal et al , 1974; Ville, 1968). Oxidizing agents from these proteins may liberate copper.…”

Exotic marine organisms, Garveia Franciscana, called “Pelo de Oso” by the locals, were detected in Lake Maracaibo. “Pelo de Oso” constitutes one of the three components of the metal/biota/solution system that interact in Lake Maracaibo, producing biofouling and microbiological corrosion. The latter generates great economic problems, mainly: water‐pump failures. The objective of this paper was to determine the preference of these bioorganisms for materials, when immersed in Lake Maracaibo.

“…The adrenal glands markedly increased in weight-an index of stress. 43 The changes in copper and iron storage which occur during pregnancy, suckling, and infancy were reviewed by Linder and Munro in 1973. We know that during the suckling period breast milk contains little copper and iron; the amount of copper and iron stored in the infant's liver should therefore decrease in the first six months of life.…”

Since sodium diethyldithiocarbamate (SDEDTC) is known to increase the tissue uptake of copper, we have examined its effect on copper accumulation in the rat cerebellum, hypothalamus, parietal cortex and hippocampus by means of atomic absorption spectrophotometry. Acute SDEDTC (1,000 mg/kg i.p.) administration alone did not alter the regional concentration of copper in the cerebellum, hypothalamus and parietal cortex, but significantly increased it in the hippocampus, 5 h after treatment. Copper acetate (5 mg/kg) given i.p. has a stimulatory effect on copper uptake only in the hypothalamus and hippocampus. When copper acetate was administered to rats which were pretreated with SDEDTC, an especially high significant increase in the hippocampal copper level could be observed (approximately 70%), while the enhancement in cerebellar copper concentration was much more lower (approximately 20%), but yet significant. These data suggest that SDEDTC enhances the uptake of exogenous copper in all brain regions examined since the lipophilic SDEDTC-copper complexes easily penetrate the cell membranes. Furthermore, our histochemical findings indicate that--under normal conditions--copper is stored predominantly in glial cells, while following an excessive uptake this metal is also accumulated in neurons (e.g. pyramidal cells of the hippocampus and cortex).
