background: bifenthrin and acorus calamus linn extract were evaluated against dengue vectors in the laboratory. methods: both bifenthrin and acorus calamus linn crude hexane extract were bioassayed against the adults and larval stages of dengue vectors aedes aegypti l. and aedes albopictus(skuse) in the laboratory. results: the a. calamus crude hexane extract exhibited a larvicidal activity aga...

the purpose of this study was to evaluate the effects of scrophularia striata water extract on the quality and shelf life of the rainbow trout fillet during superchilled storage. fish samples were treated with 1% and 3% s. striata water extract and then stored at -2°c for 20 days. the samples were analyzed periodically for chemical, microbial and sensory characteristics. results indicated that ...

the major objectives of this study were to find out the mechanism behind the sapstaining fungal hyphae penetration into wood elements using electron microscope and to evaluate the exact role of phenolic compounds existing in wood vinegar towards the sapstaining fungal growth inhibition. to formulate the new environmental friendly wood preservative, we neutralized (to ph 7) wood vinegar with nao...

with using antibiotic in societies which usage of this kind of the drug without any limitation cause appear resistance against antibiotics.this survey consider to use the extract and essence of the cinnamon (which have a so many rate of planting in iran) and also survey on extract on bacteria whose cause urinary tract infections, and compare this with common antibiotics. this study was experime...

some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. the present study was designed to investigate the effect of aqueous and ethanolic extracts of teucrium polium (t. polium) on glucose movement across the dialysis tube. the t. polium powder was dissolved in ethanol and distilled water. then glucose was added to make a final concentration of 0.2 – ...

objective: the aim of the present study was to elucidate the possible biochemical improving effect in lipid metabolic that may result from continuous treatment with green tea extract in normal albino rats and those rendered hyperlipidemic by long term supplementation of fat-enriched diet. materials and methods: fifty male albino rats aged six weeks with 200±10 g weight were randomly divided int...
