Characterization Of A PorosTm-Fumonisin B1 Affinity Column For Isolating Ceramide Synthase From Rat Liver, S. Jernigan, W. B. Melchior Jr., G. R. Jenkins, K. L. Rowland, D. W. Roberts, P. C. Howard, H. Tolleson

Journal of the Arkansas Academy of Science

Fumonisin B1 is a mycotoxin produced by fungi of the genus Fusarium, common pathogens of corn and other grain plants. Toxic effects associated with fumonisin B1 include equine leukoencephalomacia, porcine pulmonary edema, rat renal carcinoma, and murine hepatocellular carcinoma. Increased risk for esophageal cancer in humans has been epidemiologically associated with consumption of corn contaminated with Fusarium, suggesting that fumonisin B1 may be involved. The biological effects of fumonisin B1 exposure result primarily from disruption of de novo sphingolipid biosynthesis via inhibition of ceramide synthase. Exposure of animals or cultured cells to fumonisin B1 results in the characteristic accumulation of …

In Vivo Interaction Between Cadmium And Essential Trace Elements Copper And Zinc In Rats, H. Hakan Aydin, Canan Çoker, Bi̇ltan Ersöz

Turkish Journal of Medical Sciences

The complex in vivo interaction between Cd, a toxic metal and essential trace elements, mainly Zn and Cu, has not been elucidated yet. The objective being the elucidation of this interrelationship, Cd was subcutaneously administered as CdCI_2 (1 mg/kg/day) for 5 consecutive days to Swiss albino male rats (n=10). After 5 days, the rats were decapitated. Cd, Zn and Cu levels were estimated in hepatic, renal, cardiac and skeletal muscle specimens. Cd was found to be significantly elevated in all tissues (p< 0.001). Zn was increased in hepatic and renal tissues (p< 0.001 and p< 0.05) compared to the controls. Cu was also significantly increased in these tissues. Myocardial and skeletal muscle tissues also manifested a significant increase in Cu and Zn in this group. It is concluded that Cd administration alters the Zn and Cu status in vivo. However, the mechanism underlying the interactions between toxic and essential elements should be further investigated.
