introduction: many people are used medicinal plants due to natural, low risks and complications, and low costs as compared with the synthetic drugs. incidence of drug resistance against chemical antimicrobial drugs has led the use of medicinal plants for treatment of infections in recent years. the aim of this study was to examine possible antibacterial effects of four herbal plants in vitro.  ...

objective: the present study is based on an ethnobotanical research project conducted in hormozgan province that is located in south of iran, bordering waters of the persian gulf and oman sea. this survey was carried out in order to recover the ethnobotanical and ethnomedicinal knowledge of the residents of this province. they are using medicinal and functional plants for treating or preventing...

the intensity of noise, heat and light were measured in 10 different groups of food processing plants with 3820 employees. noise was measured in 265 working places and if the over-all noise was more than t.l.v. (90dba), the octave band analysis was carried out. effective temperature (e.t) or corrected effective temperature (c.e.t) were measured in 183 working places and air velocity relative hu...

objective(s) due to increasing emergence of drug-resistance in helicobacter pylori isolates, traditional plants are potentially valuable sources of novel anti-h. pylori agents. in this research, anti-h. pylori activity of the organic extracts of twenty native iranian plants was determined against ten clinical isolates of h. pylori. materials and methods disc diffusion was used to determine the ...

investigations have been carried out on the indoor air pollution in .different workshops of food processing plants in iran. in order to evaluate the exposure of workers to the three most commonly used indices of air pollution ten food processing plants representing ten groups of food industry with 2.816 workers were selected. air borne contamination of different origins such cotton seed. barley...

Stomatal resistances and turgor pressures were measured during a 12-day period on leaves of bean (Phaseolus vulgaris L. cv. Contender) which were treated with kinetin, were salinized or were treated with kinetin and salinized. Stomatal resistances were highest in salt-stressed plants, and progressively lower in salt-stressed and kinetin-treated plants, control plants, and kinetin-treated plants...

Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...

Oxidative stress is a major threat for plants exposed to various environmental stresses. Previous studies found that transgenic potato plants expressing both copper zinc superoxide dismutase (CuZnSOD) and ascorbate peroxidase (APX) (referred to as SSA plants), or nucleoside diphosphate kinase 2 (NDPK2) (SN plants), showed enhanced tolerance to methyl viologen (MV)-induced oxidative stress and h...
