The pharmacological properties of ten tertiary, hybrid and quaternary alkaloids isolated from the barks of Strychnos usambarensis roots have been investigated. Usambarensine, a tertiary bis-indole alkaloid, inhibits the muscarinic effects of acetylcholine. Four ammonium quaternary products (C-dihydrotoxiferine, afrocurarine ( a new compound), C-curarine and C-calebassine are potent curarizing agents. [less ▲]

Forest management problems require a great number of varied informations. The use of computers involves a rigorous organization, which has led the author to study the constitution of a data bank. The data bank described in this paper is made up of four main permanent and dynamic files separately built but strongly connected, comprising : general statistic of the studied forest, qualitative and quantitative stands descriptions and ecological informations. The basic descriptive unit is the plot, or any other fixed forest unit which allows for data and the results of treatments to be updated. In addition to the four main files, three other files are dealing with the study of various simulation problems, automatic mapping by the computer and use of informations provided by forest yield tables.
