Constant reduction of stratospheric ozone layer and the increase of ultraviolet radiation intensity were observed in last twenty years of the 20th century. Four tree species; Acacia amplicepsis, Acacia gerradii, Casuarina glauca and Eucalyptus intertexta grown in Experimental station of Food and Agriculture Sciences Collage, King Saud University were used to study the impact of UV-C on potentia...

Seeds of many arid habitat plants have a water-impermeable coat and can germinate only after being scarified. Bruchine seed beetles are important parasites of legume seeds in these environments, but their effect on germination can be unpredictable. Beetles deplete seed resources and can kill the embryo but also scarify seeds. We investigated the effects of a generalist parasite, Stator limbatus...

Aim of the study: To determine the pharmacological activity relevant to ulcer healing of Acacia farnesiana (aroma) leaf, a folk medicine used in the treatment of Ulcer. Materials and Methods: MEAF extract was done by using soxhelet apparatus and was further subjected to screening of the qualitative analysis of phyto chemicals. Consequently the Methanolic extract of leaf was tested against ulcer...

We report the chemopreventive activity of Acacia nilotica (Linn.) gum, flower and leaf aqueous extracts, on 7,12-dimethylbenz(a)anthracene (DMBA) induced skin papillomagenesis in male Swiss albino mice. Animals were divided into following groups: Group I (Controls) given DMBA and croton oil, with no extract ; Group II (treatment) animals treated with Acacia nilotica gum (Group II-a) (800 mg/kg ...

The routine metabolic rate of Pseudocrenilabrus multicolor victoriae, laboratory-reared, F1 offspring of parents collected from a hypoxic swamp, did not differ between sibs raised under normoxia and hypoxia. In the offspring of parents originating from a river where the oxygen levels were generally high but fluctuating, the metabolic rate of fish raised under normoxia was higher than for sibs r...

Gastrointestinal nematodes are a major threat to small ruminant rearing in the Sahel area, where farmers traditionally use bioactive plants to control these worms, including Acacia nilotica and Acacia raddiana. The main aim of this study was to screen the potential anthelmintic properties of aqueous and acetone extracts of leaves of these two plants based on three in vitro assays: (1) the egg h...
