Title: Brown-colored deposits on hair of female rats chronically exposed to 60-Hz electric fields

Abstract

An increased incidence and severity of a brownish coloration of hair has been observed around the nose and on the ears of female rats that were chronically exposed to 60-Hz electric fields. Microscopic examination of the colored areas revealed a red-brown globular deposit on hair shafts in affected areas without signs of physical injury.

  • A study was undertaken to investigate subtle bioeffects in Sprague-Dawley rats chronically exposed to a 60-Hz electric field at 80 kV/m unperturbed intensity. The details of our exposure facility, artifact considerations, environmental conditions, and exposure protocol are reported in this paper. Results of electric field exposure on reproduction and prenatal and postnatal development of rats over four generations are discussed. Statistical analysis of data from 305 females, 213 pregnancies, and 2683 births revealed no effects of electric field exposure on fertility, fecundity, nurturing, survival, or sex ratio of off-spring. In the final generation, 51 pregnant females were euthanized between daysmore » 16 and 20 of gestation, and 681 fetuses were carefully examined for gross malformations. Statistical analysis indicated that exposure to the electric field produced no significant increase in gross malformations, nor were any differences noted in resorptions, orientation of fetus in utero, sex ratio, or differential frequencies of uterine horn implantation. A detailed discussion of statistical power and sensitivity is included.« less
  • The effect of 120-day exposure to a high-intensity (80 kV/m), 60-Hz electric field on histology of selected internal organs of Sprague-Dawley rats was investigated. The organs examined were the pituitary, thymus, heart, lungs, liver, spleen, right and left adrenals, right and left kidneys, and right and left testes. Histological examination of 10-micron tissue sections from randomly selected animals revealed no specific evidence of histopathologic differences between field-exposed and sham-exposed animals at the light microscopic level.
  • An automated blood sampling system was developed for use with tethered baboons (Papio cynocephalus) during concurrent exposure to 60 Hz 30 kV/m electric fields and 0.1 mT (1.0 G) magnetic fields. The system was controlled by a FORTH-based microcomputer, which operated a pump, a fraction collector, and two pinch valves. A swivel mechanism at the end of the tether allowed the baboons to move freely in their cages. The hardware and software were designed for fail-safe operation. Heparinized saline was infused at a rate of 0.5 ml/min until a sample cycle was initiated. Then, blood was drawn from the animalmore » into a storage tube at a rate of 12.5 ml/min, a sample of undiluted blood was taken from the end of the storage tube near the baboon, and the blood remaining in the storage tube was then flushed back into the animal. Use of the storage tube prevented the peristaltic pump rollers from pressing on tubing containing blood, and return of the blood diluted with saline limited the blood wasted per sample to less than 0.5 ml. The system functioned reliably in three experiments, collecting samples as scheduled 97% of the time. Although it was initially designed for and used successfully with primates in an electric and magnetic field environment, this type of system could be employed in many areas of biomedical research or medical treatment.« less
  • In recent years, there has been increased concern regarding effects of operator exposure to the electromagnetic (EM) field associated with shortwave diathermy devices. The present study was designed to investigate the effects, on rats, of repeated exposure to such an EM field. Following repeated exposure for 5 wk, a reduction in fertility occurred as indicated by a reduced number of matings in exposed rats compared to sham-irradiated rats and a reduction in the number of rats that conceived after mating. The data suggest that female operators could experience reduced fertility, if they remained close to the console for prolonged periods.more » This has particular significant for the physiotherapy profession.« less
  • This study determined whether chronic exposure of female lambs to the electric and magnetic fields (EMF) of a high voltage transmission line can alter pineal secretion of melatonin and the normal occurrence of puberty. Twenty female Suffolk lambs were assigned randomly in equal numbers to a control and a treatment group. Treatment from 2 to 10 mo of age consisted of continuous exposure within the electrical environment of a 500-kV transmission line (mean electric field 6 kV/m, mean magnetic field 40 mG). Treated lambs were penned directly beneath the transmission line; control lambs were maintained in a pen of similarmore » construction 229 m from the line where EMF were at ambient levels (mean electric field < 10 V/m, mean magnetic field < 0.3 mG). Melatonin was analyzed by RIA in serum of blood samples collected at 0.5-3-h intervals over eight 48-h periods. To assess attainment of puberty, serum concentrations of progesterone were determined by RIA from blood samples collected twice weekly beginning at 19 wk of age. Concentrations of circulating melatonin in control and treated lambs were low during daylight hours and increased during nighttime hours. The characteristic pattern of melatonin secretion during nighttime (amplitude, phase, and duration) did not differ between control and treatment groups. Age at puberty and number of subsequent estrous cycles also did not differ between groups. These data suggest that chronic exposure of developing female sheep to 60-Hz environmental EMF does not affect the mechanisms underlying the generation of the circadian pattern of melatonin secretion or the mechanisms involved in the onset of reproductive activity.« less
