abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...

the hypotensive effect of garlic has been well-documented in human subjects and animals. since endothelial activity regulates vascular reactivity in physiological and pathophysiological conditions, the aim of the present study was to investigate the effect of garlic on endothelium-dependent and independent relaxation of rat aorta for elucidation of mechanism of the garlic anti-hypertensive effe...

background: diabetes mellitus is considered one of the 5 principal causes of death in the world and is recognized as a global public health issue because of its multifactorial facets affecting essential biochemical processes in the body. this study investigated the antidiabetic and antidyslipidemic activities of the aqueous extract of cochlospermum planchonii (c. planchonii) leaves in streptozo...

Recent research has indicated that increased vulnerability to oxidative stress may be the major factor involved in CNS functional declines in aging and age-related neurodegenerative diseases, and that antioxidants, e.g., vitamin E, may ameliorate or prevent these declines. Present studies examined whether long-term feeding of Fischer 344 rats, beginning when the rats were 6 months of age and co...

abstract anti-nociceptive activity of aerial parts of phytolacca americana were investigated, using the hot plate method in mice. results of the present study showed that the aqueous methanolic extract of aerial parts of p. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (p<0.001). the activity was c...

In order to investigate the effects of allelo-pathic substances Conyza canadensis on seed germination and seedlings, this study was designed explore allelopathic water extract (CCE) pakchoi, spinach lettuce. Germination rates three crops (pakcholi, spinach, lettuce) during germination, root length, seedling height, fresh weight two (pakcholi were measured under different concentrations CCE trea...

The radioenzymatic method was used to determine the oxalate contents in common Japanese foods. High concentrations of oxalate were detected in spinach, Perilla frutescens, pepper, sesame, chocolate, and tea. Beer and coffee also contained some oxalate. Fruit and meat were low in oxalate content. Therefore, among the common Japanese foods, the most important foods to be avoided to restrict oxala...

introduction: previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of drosera spatulata (droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (pgi) nucleus is part of bra...
