The potential antihypertensive activity of Brazilian plants was evaluated in vitro by its ability to inhibit the angiotensin-converting enzyme (ACE). Forty-four plants belonging to 30 families were investigated. Plants were selected based on their popular use as antihypertensive and/or diuretics. The following plants presented significant ACE inhibition rates: Calophyllum brasiliense, Combretum...

OBJECTIVE To describe and to characterize the relaxing effect of an extract of the bark of Combretum leprosum on isolated arterial rings from different animals. METHODS Rings (3 to 4mm) from rabbit, rat, or porcine arteries rings were suspended in an organ bath (Krebs, 37°C, 95%O2/5%CO2) to record isometric contractions. After the stabilization period (2 to 3 hours) contractions were induced ...

WSR-88D operators have been trained to look for tornado signatures using base reflectivity and storm relative motion. Despite improvements stemming from the implementation of the WSR-88D network, these conventional signatures are not always evident in tornadic situations. At other times, these signatures may exist without tornadic development, even when environmental parameters appear favorable...

Lepidodendron hickii is tlie only anatomically preserved Carboniferous lepidodendrid with leaf cushions referable to the compression-based L. aculeatum, the type of Lepidodendron. Historically Lepidodendron has come to encompass several kinds of arborescent lycopods with distinctive vegetative and reproductive morphologies, among which no truly intermediate forms are known. These include totall...

The study investigated the antibacterial activity of crude extracts of C. edwardsii, Combretum krausii, and Maytenus nemorosa as well as their interactions with selected antibiotics against drug resistant bacterial strains. Using the rapid p-iodonitrotetrazolium chloride colorimetric assay, minimum inhibitory concentration values of plant extracts and antibiotics were determined. The interactio...

Crude methanol and water extracts of 36 plants, employed in the treatment of diseases of probable bacterial etiology by the Venda people, were screened for antibacterial activity. Combretum molle, Peltophorum africanum, Piper capense, Terminalia sericea and Zanthoxylum davyi were the most active and presented MIC values < or =1.00 mg/ml.
