Multiple sclerosis causes demyelination of central nerve fibers, and it is this pathology which results in most of the symptoms of the disease. The repair of the fibers by remyelination has been advanced as a potential symptomatic therapy, but at present the conduction properties of remyelinated central fibers are not well understood. In this study the conduction properties of Schwannian or oligodendrocyte remyelinated central nerve fibers have been determined. In addition, the status of the blood-brain barrier has been examined in lesions characterized by Schwann cell remyelination. These lesions chronically lack astrocytes, a cell believed to be involved in the …

The targeting of proven anticancer drugs specifically to cancer cells would provide a unique opportunity to restrict neoplasms without damaging the cancer patient. The present research utilizes the phenomenon of illicit transport, i.e. the coupling of normally impermeant metabolites to permeant metabolites, in targeting the drug melphalan to mouse Ehrlich ascites tumor cells. The dipeptide beta-alanyl-melphalan was synthesized and tested in vitro for toxicity towards mouse Ehrlich ascites tumor cells, mouse liver cells, and mouse 3T3 embryonic cells. The parent compound, melphalan, was used as a control treatment. In addition, both melphalan and beta-alanyl-melphalan were utilized in in vivo chemotherapeutic …
