Inflammation: the foundation of diseases and disorders. A review of phytomedicines of South African origin used to treat pain and inflammatory conditions.
The basic mechanisms of inflammation and the potential of 123 southern African plant species to be effective as chronic inflammatory disease preventive agents are reviewed.
Extraction of antibacterial compounds from Combretum microphyllum (Combretaceae)
In vitro activity of Peltophorum africanum Sond. (Fabaceae) extracts on the egg hatching and larval development of the parasitic nematode Trichostrongylus colubriformis.
Effect of temperature and light on the toxicity and growth of the blue-green alga Microcystis aeruginosa (UV-006)
The toxicity and growth of Microcystis aeruginosa from the Hartbeespoort Dam, South Africa were investigated at different temperatures and photon fluence rates under laboratory conditions, finding toxicity tended to be less at the very low and high light fluences.
The biological activity and chemistry of the southern African Combretaceae.
Naming of cyclic heptapeptide toxins of cyanobacteria (blue-green algae).
