In this study the extracts of the Iraqi herb Tribulus terrestris (Al-Hassage or Al-Kutub) was done by using of polar and non polar solvents, then the biological activity of these extractants was studied in three fields, First, the antibacterial activity (in vitro) on gram positive bacteria (Staphylococcus aureus), and gram negative bacteria (E. coli, Proteus vulgaris, Pseudomonas aerugiuosa, an...

BACKGROUND Our group previously found that up to 7% of amateur anglers in Caceres, Spain may be allergic to the larvae of Protophormia terraenovae (order Diptera, family Calliphoridae) used as live bait for fishing. OBJECTIVE To identify the pattern of major allergens in P terraenovae and other species of Calliphoridae. MATERIALS AND METHODS Extracts of P terraenovae, Calliphora vomitoria, ...

The impact of growth temperature was evaluated for the fungal plant pathogen Mycoleptodiscus terrestris over a range of temperatures (20 368C). The effect of temperature on biomass accumulation, colony forming units (cfu), and microsclerotia production was determined. Culture temperatures of 24 308C produced significantly higher biomass accumulations and 20 248C resulted in a significantly high...

Background Spermatogenesis is a process in which the gametes are produced. Dysfunction in any of part of the process could result in infertility. Tribulus terrestris is a flowering plant which traditionally is used to sexual instinct. Reports indicate that this plant could elevate blood levels testosterone and enhance libido. MaterialsAndMethods In this experimental study, twenty six mature inb...

objective: in this study, antimicrobial activities of an ethanol extract of tribulus terrestris aloneand in combination with capsella bursa-pastoris and glycyrrhiza glabra were examined in vitro against six pathogens namely streptococcus mutans, streptococcus sanguis, actinomyces viscosus, enterococcus faecalis staphylococcus aureus, and escherichia coli. materials and methods: antibacterial ac...

OBJECTIVE The aim of the current study is to investigate the influence of Tribulus terrestris extract on androgen metabolism in young males. DESIGN AND METHODS Twenty-one healthy young 20-36 years old men with body weight ranging from 60 to 125 kg were randomly separated into three groups-two experimental (each n=7) and a control (placebo) one (n=7). The experimental groups were named TT1 and...

Kin selection theory predicts conflict in social Hymenoptera between the queen and workers over male parentage because each party is more closely related to its own male offspring. Some aspects of the reproductive biology of the bumble-bee Bombus terrestris support kin selection theory but others arguably do not. We present a novel hypothesis for how conflict over male parentage should unfold i...

BACKGROUND In addition to their general role in the hydrolysis of storage lipids, bumblebee lipases can participate in the biosynthesis of fatty acids that serve as precursors of pheromones used for sexual communication. RESULTS We studied the temporal dynamics of lipolytic activity in crude extracts from the cephalic part of Bombus terrestris labial glands. Extracts from 3-day-old males disp...
