Acute selenium poisoning by paradise nuts (Lecythis ollaria).

Neuroprotective effect of Sapucaia nuts (Lecythis pisonis)on rats fed with high-fat diet.

BACKGROUND Lecythis pisonis Cambess is commonly known as "castanha de sapucaia" in Brazil. Chemical composition studies revealed that this nut is an excellent source of anti-oxidant minerals and of essential lipids. OBJECTIVE The aim of the present study is to assess the anti-oxidant and anti-inflammatory effect of Lecythis pisonis Cambess on the brain tissue of Wistar rats. MATERIAL AND ME...

Review: Evaluating Selenium Poisoning

Selenium poisoning in humans is reviewed from the perspective of the clinical laboratory. While evaluation of selenium poisoning is straightforward when the analytic results are markedly elevated and the patient is acutely symptomatic, distinguishing toxic from non-toxic elevations is a more frequent issue and more challenging. A significant problem is that selenium is determined as its total c...

Brazil nuts: an effective way to improve selenium status.

BACKGROUND Brazil nuts provide a rich natural source of selenium, yet no studies have investigated the bioavailability of selenium in humans. OBJECTIVE We investigated the efficacy of Brazil nuts in increasing selenium status in comparison with selenomethionine. DESIGN A randomized controlled trial was conducted with 59 New Zealand adults. Participants consumed 2 Brazil nuts thought to prov...

Sodium selenate

Human toxicity Elemental selenium metal has a relatively low order of toxicity. Acute poisoning with selenium and its salts are rare, however, in excessive amount toxic and even fatal action was documented. Normal whole blood selenium levels in adults range from 0.085 to 0.13 mg/l [2]. All selenium salts can produce toxicity by ingestion, inhalation, and percutaneous absorption, although specif...
