This study analyses the interest of isologous venous grafts filled with saline or with Schwann cells versus nerve grafts as guides for regeneration of the sciatic nerve in 35 Wistar rats. Electrophysiological parameters (conduction velocities and dis

We analyzed and tried to characterize substance(s) responsible for cytotoxic activities detected in culture media conditioned by non pigmented B16 melanoma cells (NPB16). The different cytological tests used showed that ultrafiltrated conditioned med

The effects of selenium compounds such as sodium selenite, sodium selenate, seleno-Dl-cystine and seleno-Dl-methionine (100 μM and 10 μM) on B16 and pigmented cloned pB16 murine melanoma cells were investigated in vitro. At the tested concentration

In this paper, we describe the isolation and structural determination of 2,7-dihydroxyapogeissoschizine, a new alkaloid from the root bark of Strychnos gossweileri. Elucidation of its structure is based mainly on 1D and 2D NMR studies; its conformati

A murine B16 melanoma parental line (B16) and two clones either pigmented (B16P) or non-pigmented (B16NP) were cocultured as aggregates with mouse 3T3 fibroblasts. In vivo, these mixed aggregates developed more aggressive tumors in the mouse than cor

Matadine, a new alkaloid, has been isolated from the root bark of Strychnos gossweileri. Elucidation of its structure is mainly based on 1H and 1D NMR studies. Its cytotoxic activity has been tested on cancer cells and normal cells. Matadine is an an

This paper describes the powerful cytotoxic action exerted by strychnopentamine (SP), a dimeric indole alkaloid extracted from Strychnos usambarensis Gilg, on B16 melanoma cells and on non-cancer human fibroblasts cultured in vitro. SP strongly inhib

The structure of strychnofluorine, an indole alkaloid isolated in 1980 from the root bark of Strychnos gossweileri, has been revised. Strychnofluorine proved to be identical with 18-hydroxynorfluorocurarine that has been isolated as a minor (contamin

In this work, we have analysed the effects of alpha-hederin, a monodesmosidic triterpenoid saponin isolated from Hedera helix, on mouse B16 melanoma cells and non-cancer mouse 3T3 fibroblasts cultured in vitro. Our results indicate that, in a serum-f
