- ... The intestinal absorption of trivalent and hexavalent chromium (Cr) given orally (experiment I) or infused in the intestine (experiment II) was investigated in rats. The nonabsorbable form of chromium (⁵¹Cr ₂O ₃) and water-soluble and more absorbable Na ₂⁵¹CrO ₄ (the hexavalent form of Cr) were compared. Total retention of chromium given orally ranged around 15 percent of the dose, regardless of t ...

- ... Aims: To examine the hypothesis of non-immune defence mechanisms based on nitrite. Methods and Results: The acidified media (nutrient broth or citrate-phosphate buffer) under aerobic conditions with additions of physiological levels of nitrite, L-ascorbic acid, iodide and thiocyanate were used to simulate gastric juice. The bactericidal effects of acidified nitrite on Escherichia coli and lactobac ...
