Animal productions are the results of interactions between the genetic potential of the animal, environmental factors and nutrient supplies. These interactions modulate the endocrine system, especially the somatotrope axis. IGFBP-3 is the major carrier of the IGFs (the main growth-promoting peptide) in plasma circulating as part of a 150 kDa ternary complex with one IGF peptide and a single acid-labile subunit. The IGFBP-3 purification would allow the measure of the changes in plasma IGFBP-3 throughout the day and the development and in various physiological situations. We try to purify the bovine IGFBP-3. Firstly, we load 0,5 ml of serum onto an Hiload 16/6 Superdex 200 prep grade column, then onto an ion exchange column and finally onto an IGF-I affinity column. The purification fails perhaps because the sample is to small. Secondly, 5 ml of serum is fractionated by 3 gel filtrations. Between the first and the second filtration, the fractions containing IGF-I binding activity are pooled and concentrated. Before the third gel filtration, the fractions containing this activity are pooled anew, acidified with HCl and incubated at 4 °C for 2 hours. The third gel filtration fractions are pooled and subjected to an heparin-affinity chromatography. The elution pic shows only IGFBP-3 activity. In conclusion, our purified product contains other proteins. But the ternary complex is dissociated, so an IGF-I affinity chromatography would purify the IGFBP-3 from the elution pic of the heparin-affinity column. [less ▲]

This paper gives results of phytochemical screening on some thirty medicinal and toxic plants mainly collected in Eastern Rwanda ( national ParK of Akagera). these plants belong to variuos genera ( Acacia, Albizia, Anthocleista, Apodytes, Cassia, Cissampelos, Clematis, Dichrostachys, Fagara, Harrinsonia, Impatiens, Ipomoea, Kniphofia, Olea, Osyris, Parinari, Rhamnus, Rytigynia, Sesbania, Solanum, Strychnos, Thonningia, Tylophora, Ximenia). Previuosly no plant of this country had been chemically studied. [less ▲]

Essai de typologie industrielle des communes belges La typologie industrielle proposée dans cet article est sans conteste le premier essai de classification des communes belges intégrant à la fois l'importance du fait industriel dans la commune et le type d'industries présentes. Au départ des 36 données sélectionnées dans les statistiques du Cadastre et de l'O.N.S.S., 11 variables ont été construites. L'analyse en composantes principales a permis d'individualiser quatre facteurs rendant compte de près de 80% de la variation totale; ces quatre composantes sont représentatives de la grande industrie, de l'industrie légère, du poids industriel (part relative de l'industrie dans la commune) et des fabrications métalliques. Sur base des scores obtenus sur ces quatre composantes, il a été ensuite possible d'établir une typologie des communes en huit classes ayant chacune un profil précis, profil qui, par ailleurs, oppose sou¬vent Flandre et Wallonie, communes rurales et centres urbains.
