The Effect of an Eextremely Low Frequency Magnetic Field on Larvae Production in the Parasite-Host System: Fasciola hepatica-Galba truncatula: a Preliminary Study.

The aim of this study was to determine the effect of an extremely low-frequency magnetic field (ELFMF) on the production of liver fluke larvae in a parasite-host system: Fasciola hepatica--Galba truncatula. Both F. hepatica eggs and F.

Extremely low frequency magnetic field and the hatching rate of Fasciola hepatica eggs, the fecundity and survival of liver fluke-infected snail, Lymnaea truncatula.

Eggs of Fasciola hepatica were exposed for 10 days to extremely low frequency magnetic field (ELFMF) at the frequency of 50 Hz and density of 2 mT (rms). The results show an accelerated hatching of F. hepatica eggs in relation to control (non-exposed) group.

Effects of extremely low-frequency magnetic fields on the oviposition of Drosophila melanogaster over three generations.

The aim of this study was to determine the effects of an extremely low-frequency 50 Hz magnetic field (ELFMF) on the oviposition and development of Drosophila melanogaster. The results show that exposure of D. melanogaster females of generation P and all the development stages of generation F1 to an ELFMF weakened the oviposition of these insects in their subsequent generations.

[In vitro level of L-ascorbic acid radical in lenses of patients with senile or diabetic cataract--preliminary study].

Introduction: To estimate the in vitro level of L-ascorbic acid radical in lenses of patients with senile or diabetic cataract using EPR (Electron Paramagnetic Resonance) spectroscopy.

Material And Methods: 24 human cataractous nuclei obtained during extracapsular removal were used. 5 of them (21%) were from diabetic patients.

Increased lipid peroxidation and ascorbic Acid utilization in testis and epididymis of rats chronically exposed to lead.

The hypothesis has been recently presented that lead may exert its negative effect at least partially through the increase of reactive oxygen species (ROS) level in tissues. However, little is known about the influence of lead intoxication on equilibrium between generation and elimination of ROS in the male reproductive system. Sexually mature male Wistar rats were given ad libitum 1% of aqueous solution of lead acetate (PbAc) for 9 months.

Effect of electric power network frequency magnetic field on embryonic development of Ascaris suum (Nematoda).

Fertilised Ascaris suum eggs were subjected to an alternating electromagnetic field of frequency 50 Hz and density 2 mT for 60 days. The developing embryos in both control and experimental cultures were examined daily under a microscope. The experiment resulted in an accelerated rate of embryogenesis in the eggs incubated in the electromagnetic field, higher rates of malformed embryos as well as much higher mortality rate of L2 larvae.

Influence of the storage time and the method of stimulation on whole blood chemiluminescence.

The ultra-weak light, chemiluminescence (CL), of stimulated leukocytes is a well-known phenomenon. Parameters of this CL are modified by many factors including laboratory procedures. The order of stimulation and enhancement (two possibilities) and two concentrations of luminol create four types of procedure, which were accomplished in five sample storage 'time points'.
