to determine the neuropharmacological activity of the leaf extract of croton zambesicus in mice and chicks. the effect of aqueous leaf extract of croton zambesicus on thiopental sodium – induced sleeping time in mice, on gross locomotor activity (gla) in 2-day old chicks and effect of extract on apomorphine - induced stereotyped behavior in chicks were evaluated. the aqueous extract (1000 and 1...

When Dr. Charles Arntzen of Arizona State University visited Thailand in 1992, he was not expecting a moment of scientific "eureka" that would redirect his career. However, after observing a young Thai mother soothing her fussy infant with bits of banana, this plant molecular biologist was struck with an idea that is both startling and ingenious. What if, in addition to quieting her child, the ...

Background & Aim: Natural compounds can prolong the shelf life of food by inhibiting the growth of pathogenic and spoilage microorganisms. The purpose of this study was to investigate the effect of Sheng and Ziziphora alcoholic extracts (at concentrations of 500, 1000 and 1500 ppm) on physico chemical properties and microbial quality of yogurt. Experimental: </str...

crude enzyme (beta-galactosidase) extract (cee) was produced by lactobacillus ssp. bulgaricus chr hansen lb-12 and was applied in sterile milk which had been processed through ultra high temperature method (uht milk), for hydrolyzing lactose. lactosehydrolyzed milk was also produced by a pure and commercially available betagalactosidase (maxilact). optimum quantities of cee and maxilact enz...

the carob moth is one of the most devastating pests of pomegranate and some other products. various pest control measures have been undertaken in order to control this pest but none of them has been successful so far. in the current study the effects of cereal seed proteinaceous extracts including triticale and three wheat cultivars (mv17, aflak, and zare) have been studied on α-amylase and pro...

the presence of tribolium castaneum (herbst) in a stored food results in contamination and substantial economic damage due to loss of the products and a decrease in nutritional value. this study was conducted to determine the pesticidal and pest repellent activities of roots of laportea crenulata gaud. against t. castaneum. pesticidal activity was determined using surface film method, whereas, ...

in the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium leuconostoc mesenteroides nrrl b512 (f) was investigated. in comparison to blue dextran (mw≈2000 da), dextran molecular weight was reduced (mw2000 kda). flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...

the objective of present study was to investigate the effects of aqueous garlic extracts, vitamin e and n-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. twenty-five male rats were divided into five groups. animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...
