BACKGROUND Dracaena cinnabari (DC) is a perennial tree that located on the Southern coast of Yemen native to the Socotra Island. This tree produces a deep red resin known as the Dragon's blood, the Twobrother's Blood or Damm Alakhwain. The current study performed to evaluate the safety of the DC resin methanol extract after a single or 28 consecutive daily oral administrations. METHODS In ass...

Decaleside II, a novel trisaccharide isolated from the edible roots of Decalepis hamiltonii, belongs to a new class of natural insecticides. We have evaluated the mammalian safety of Decaleside II in the laboratory mouse. Our results on acute and sub acute toxicity study suggest that Decaleside II is not toxic to the laboratory mice as there were no symptoms of toxicity or mortality up to 2400 ...

2,4,6-Trichlorophenol (2,4,6-TCP) is a common chemical intermediate and a by-product of water chlorination and combustion processes, and is a priority pollutant of the aquatic environment in many countries. Although information on the toxicity of 2,4,6-TCP is available, there is a lack of information on the predicted no-effect concentration (PNEC) of 2,4,6-TCP, mainly due to the shortage of chr...

anti-oxidant properties[5]. Reinwardtia indica (family Linaceae) contains saponins, which could potentially help in the management of hyperglycemia[6–7]. We conducted acute and sub-acute oral dose toxicity studies of the test formulation in Swiss albino mice and albino Wistar rats, respectively. Single doses (10 to 5,000 mg/kg) were administered orally to mice. No treatment related deaths or cl...

background: the development of toxicity tests regarding toxic responses of different fish species could be more effectively used in predictive toxicology and risk assessment. in this study lethal concentrations (lc50-96 h) values of copper sulphate an important toxic industrial pollutant, on capoeta fusca were determined. behavioral changes at different concentrations of cuso4 were determined f...

acute liver failure (alf) is an uncommon, devastating syndrome of which over 2000 cases occur annually in the usa, with a mortality rate of about 80%. alf is de_ned by the sudden onset of hepatic encephalopathy and coagulopathy (inr_1.5) in an otherwise healthy person. the most common etiologies are acute viral hepatitis a and b, medication overdose (e.g., acetaminophen) and idiosyncratic drug ...

all aquatic organisms are directly or indirectly affected by the physical characteristics of their environment, especially the chemical composition of the water. the high concentration levels, damage tissues and interfere with the normal growth and proliferation. the aim of this research was to investigation acute toxicity of znso4 and cucl2 to gambusia holbrooki by static bioassays at differen...

the aqueous and ethanolic extracts of pedalium murex (pedaliaceae) was investigated for antipyretic activity in rats using brewer’s yeast-induced pyrexia models. brewer’s yeast (15%) was used to induce pyrexia in rats. both the extract (200 and 400 mg/kg body weight p.o produced a significant (p

the effects of hydroalcoholic extract (he) of curculigo orchioides gaertn. rhizome (hypoxidaceae) and its alkaloidal and non-alkaloidal fractions (af) and (naf) were evaluated in carrageenan-induced paw edema experimental models of inflammation. the oral administration of he, their af and naf fractions were used at doses of 100, 300 and 500 mg/kg. the effect produced by the he, af and naf fract...

Safety of medicinal plants/products is one the major areas that require more attention because high rate at which consumers use due to their availability and accessibility. Dracaena steudneri Engl. among plants being used recommended for treatment several diseases decades traditional health practitioners. Despite its frequent use, there little literature on safety. This study investigated acute...
