the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...

conclusions the results of the present study indicate the protective effects of melissa officinalis on some sperm parameters and spermatogenesis quality in rats exposed to lead. background some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. objectives the present study aimed to determine the eff...

background & aim: a simple and rapid microwave- assisted extraction (mae) procedure was developed and optimized for the isolation of borneol and bornyl acetate from ferulago macrocarpa. ferulago macrocarpa (apiaceae) is an endemic plant in iran. experimental: dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a clevenger extraction approach under opt...

background: there are controversial reports about the exact mechanisms of lead-induced hypertension, but many factors such as alteration in the responsiveness of cardiovascular system to endogenous substances including catecholamines could be one of the mechanisms involved. in present study, the effect of exposure to 100 ppm lead acetate by drinking water (in the periods of 4, 8 and 12 weeks) o...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...

introduction: wistar rats are an outbred strain of albino rats belonging to the species rattus norvegicus. histopathological studies on the testis was carried out to determine the effects of heat and lead on male fertility by evaluating some andrological parameters of the wistar rat such as morphology of spermatozoa, sperm count and motility. the main objective of this research was to compare t...
