background: barberry (berberris vulgaris) is a well known medicinal plant in iran and has also been used as food. objective: this study was conducted to evaluate antihistaminic and anticholinergic activity of methanolic extract of barberry fruit. methods: methanolic extract was prepared and pharmacologically studied on isolated guinea- pig ileum, dose- response curves of histamine and acetylcho...

objective(s): in regard to the high incidence of asthma and the side-effects of the drugs used, finding novel treatments for this disease is necessary. our previous studies demonstrated the preventive effect of nigella sativa extract on ovalbumin-induced asthma. in addition, water-soluble substances of n. sativa extract and methanol fraction of this plant were responsible for the relaxant effec...

the stimulatory effect of the extract of portulaca oleracea (p. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. to examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. values of ec50 (the effecti...

protection of animals immunized against bacillus anthracis is usually demonstrated by challenging with an appropriate dose of a strain of bacillus anthracis that is lethal to unvaccinated animals inoculated at the same time. in this study the protective efficacy in anthrax vaccine (34f2 sterne strain spore) was evaluated in sheep, goats and guinea pigs challenged with subcutaneous inoculation o...

De México, dinámica crecimiento siete líneas maíz cont...

The study used Theory of Planned Behaviour (TPB) to understand the underlying factors for intention adopt artificial insemination (AI) technology in pig by tribal farmers Nagaland. Responses from a survey 72 Nagaland revealed strong intent which is driven favourable attitude towards and approval referent groups pig. Perceived behavioural control seems be main discriminating drivers among theory...

Since, the most susceptible laboratory animal to Foot–and–Mouth disease virus (FMDV) is guinea pig, and then one milliliter of FMDV type (O) concentrations of 106-106.5 TCID50was inoculated intradermally (ID) to 10 plantar surface of guinea pig (right side). Guinea pig adapted virus has been prepared after generalization phase, and then one milliliter of virus was inoculated intradermally to 30...

On most adrenergic and cholinergic nerve terminals, prejunctional α-adrenoceptors belonging to the α2-subtype have been identified. Activation of these receptors will decrease the release of norepinephrine. It has been reported that several isolated tissue preparations contain prejunctional dopamine receptors, the stimulation of which inhibits neurotransmission. It has remained uncertain whethe...

Pig carcasses have been used in forensic research because they share several similarities to human cadaver, including decomposition. In studies, the decomposition of pig’s cadaver for a certain time can be as model determine death human. This study was conducted relationship between days spoilage pig tissue and level average sound intensity produced by sample. Then, this study, skeletal muscles...

clinical asthma and airway responsiveness appear to be less severe when diabetes is superimposed. the aim of the present study was to determine the possible role of nitric oxide (no) in the airway reactivity under diabetic and diabetic-allergic conditions. twenty-five male guinea-pigs were divided into five groups of five each as follows: diabetic, antigen sensitized, diabetic- antigen sensitiz...
