In a study to select anti-inflammatory medicinal plants, we have observed that extracts of Ribes nigrum significantly inhibited at a dose of 50mg/kg i.p. the carrageenan rat paw edema. We have now proved that the most active fractions contained proanthocyanidins . In the present study, we report on the isolation of three bioactive compounds: two prodelphinidins dimers and a new trimeric one. [less ▲]

Intrathoracic pressure measurement in cattle : standardized procedure

A procedure to standardize the position of an esophageal catheter (eso-cat) tip, used to measure intrathoracic pressure, was tested in ten healthy Dutch Friesians. The cattle were in normal condition with body weights (BW) between 52 and 670 kg and thoracic perimeters (TP) between 80 and 210 cm. The position of the neck and head was standardized. The eso-cat was introduced via the nose into the thoracic portion of the esophagus. The distance between the nares and the eso-cat tip (Lcat), which was positioned between the crossing point with the aorta and the caudal mediastinal lymph nodes, was measured for each animal. The regression equation, calculated between the Lcat and the BW and TP was, respectively: Lcat (cm) = 65 + 0.115 x BW (kg) (r2 = 0.99) and Lcat (cm) = 22 + 0.535 x TP (cm) (r2 = 0.97). The corresponding residual standard deviations were respectively 2.52 and 4.37 cm. The multiple and curvi-linear regression equation did not give a significantly better fit of the data [less ▲]

Fibronectin promotes rat Schwann cell growth and motility

Techniques are now available for culturing well characterized and purified Schwann cells. Therefore, we investigated the role of fibronectin in the adhesion, growth, and migration of cultured rat Schwann cells. Double-immunolabeling shows that, in primary cultures of rat sciatic nerve, Schwann cells (90%) rarely express fibronectin, whereas fibroblasts (10%) exhibit a granular cytoplasmic and fibrillar surface-associated fibronectin. Secondary cultures of purified Schwann cells do not express fibronectin. Exogenous fibronectin has a small effect on promoting the adhesion of Schwann cells to the substrate and does not significantly affect cell morphology, but it produced a surface fibrillar network on fibronectin on the secondary Schwann cells. Tritiated thymidine autoradiography revealed that addition of fibronectin to the medium, even at low concentrations, markedly stimulates Schwann cell proliferation, in both primary and secondary cultures. In addition, when cell migration was measured in a Boyden chamber assay, fibronectin was found to moderately, but clearly, stimulate directed migration or chemotaxis. [less ▲]

Fruits of Strychnos usambarensis may be cause of poisoning in Africa. The main alkaloid of an extract with CHCl3 at pH 5 has been isolated and identified as descarbomethoxydihydrogambirtannine; that alkaloid is found for the first time in the family of Loganiaceae.The structure of usambaridine Vi, alkaloid previously isolated from leaves, is now elucidated by analysis of NMR and UV spectra. Its structure corresponds to 10-hydroxy-usambarine. [less ▲]

Strychnine is unstable under light in chloroformic solution and is partly transformed in pseudostrychnine, genostrychnine (Nb-oxy-strychnine) and chloromethostrychninium (a quaternary derivative). In other respects the curarizing activity of African Strychnos (e.g. Strychnos usambarensis) is not due to isostrychnine as erroneously written by TURKOVIC (J.Pharm Belg. 1976, 31, 277-286) but to quaternary alkaloids like C-dihydrotoxiferine, C-curarine, afrocurarine and C-calebassine (cf L.ANGENOT et al. Arch. Intern. Pharmacodyn. Ther. 1975, 215, 246-258). [less ▲]

The thesis is subdivided in four parts and two annexes . the first part concerns the choice of Strychnos usambarensis based on ethnobotanical considerations; the second part is dedicated to the study of arrow poisons in the World and particularly in Africa; the third part describes the isolation of eight indole alkaoids ( 5 new and 3 known ones) and their structure determination thanks to modern spectroscopic methods.The fourth part is applied to the biosynthesis of these alkaloids and to the identification of loganic acid.The first appendix describes the phytochemical screening of 33 Rwandan plants mainly collected in the National Park of Akagera. The second appendix relates pharmacological experiments on crude fractions and some isolated alkaloids. [less ▲]
