In the present research, the effects of static magnetic field, with or without iron on the growth, the activity of certain
enzymes (like polyphenol oxidase and phenyle alanine ammonialyase), the content of phenolic compounds and the essential oil
composition of sweet basil (Ocimum basilicum) were studied. Treatment of plants with static magnetic field with or without iron led to decrease of the growth of plants
as well as decrease in the activity of phenyle alanine ammonialyase and of phenolic compounds content. In addition in those
plants exposed to magnetic field the amount of essential oils, notably of methyl chavicol, was increased. Exposure of plants
to the magnetic field decreased the activity of polyphenol oxidase, whereas treatment of plants with iron when exposed to
magnetic field increased polyphenol oxidase activity. In this group the content of essential oil was reduced. 相似文献

This investigation was performed to evaluate the influence of the static magnetic field (SMF) on chromosomes in Vicia faba cultivated in soil from high background natural activity. Fourteen soil samples were collected from Ramsar area, in north of Iran, which the annual radiation absorbed dose from background radiation is substantially higher than the 20 mSv/year. The specific activity of the radionuclides of 232Th, 236Ra, and 40K was measured using gamma spectrometry. The collected soil samples were then divided into 2 separate groups including HR (high natural radioactivity) and LR (low natural radioactivity). The cultivated Vicia faba in both groups were continuously exposed to SMF of 15 mT for 8 days, each 8 h/day starting from 2nd day. The chromosomal aberrations were counted in both groups with and without SMF from root of samples using chromosomal aberration method. The results showed a significant difference between treated and control plants. Chromosomal aberrations including bridge, fragments, and lagging chromosomes in prophase, metaphase, anaphase, and telophase enhanced significantly in treated groups compared with controls. 相似文献

This research was carried out to evaluate the influence of static magnetic field on the rate of apoptosis in bone marrow stem
cells (BMSCs) of rats. Extracted cells were suspended in αMEM as a culture media for 48 h. After that, cells were exposed
to 15 mT static magnetic field (SMF) for 5 h, incessantly with or without FeCl2. The rate of apoptosis was then assessed via flow cytometery. The results showed that either treatment with FeCl2 or exposure to SMF enhanced the rate of apoptotic cells. Moreover, cells that were treated simultaneously with FeCl2 and SMF have higher rate of apoptosis. An increase in apoptosis by 26.5% was induced by SMF alone and an increase in apoptosis
by 28.2% was induced by a combination of FeCl2 and SMF, compared to their corresponding controls. The results recommended that the effects of SMF on apoptosis may be related
to increment of the number of free radicals in the cells. 相似文献

Synthesis and utilization of a mesoporous nickel oxide as a novel catalyst for degradation of phenol
Mesoporous nickel oxide (MNO) was synthesized by sol–gel method with saponificated chlorophyll-a (Chl-a) as template and Ni (II) acetate as starting material. XRD, surface area, pore volume, pore diameter and pore size distribution of MNO were determined. It exhibited high surface area and uniform pores with very sharp pore size distribution centered at 3.6 nm. High resolution transmission electron microscope images confirmed the results. MNO showed a high activity toward degradation of phenol at low temperature under atmospheric pressure of oxygen. 相似文献

Bio-effects of static magnetic fields on cell growth and cell death have been investigated in suspension-cultured tobacco
cells as undifferentiated, embryonic plant cell model. The cells in their logarithmic growth phase were exposed to static
magnetic field with the magnitudes of 10 mT and 30 mT for 5 h/day. Exposure to static magnetic field ceased the growth and
caused an increase in cell death of exposed tobacco cells compared to those cells which were not treated with the field. Promotion
of cell death was accompanied by a harmonized increase in the activity of peroxidase and increase of lignifcation of cell
walls. 相似文献
