University of Oklahoma Study to Quantitate Pain When Jacobson Resonance Fields Are Directed to the Heart During Activation of Cardiac Nociceptors BusinessWire, Monday, June 22, 1998 at 10:11 BOCA RATON, Fla.--(BW HealthWire)--June 22, 1998--Pioneer Services International Ltd. (OTC BB:PSVC) announced Monday approval by University of Oklahoma Health Science Center researchers to conduct a study to quantitate the activity recorded from cells in the thoracic spinal cord that respond to nociceptive afferent information (pain) from the heart. The hypothesis of the study is that cell activity in the thoracic spinal cord decreases when Jacobson Resonance magnetic fields are directed to the heart during activation of cardiac nociceptors. Professor Robert D. Foreman, chairman of the Department of Physiology and principal investigator in this study, said: "Anecdotal reports suggest that magnetic fields provide different levels of pain relief in a variety of pain patients. Well documented studies to quantitate the effectiveness of electromagnetic fields do not exist in the literature. To address the hypothesis, we will determine the effects of Jacobson Resonance magnetic field stimulation on extracellular action potentials of spinal neurons located in the gray matter of the T5-T8 spinal cord segments in rats. To demonstrate that EM field stimulation affects noxious information arising from the heart, intrapericardial injections of 'inflammatory soup' will be used to activate cardiac receptors of sympathetic afferent fibers projecting to the spinal cord. Jacobson Resonance magnetic field stimulation will be administered while spinal neurons increase their activity as a result of the chemical injections." Electromagnetic stimulation will be applied during peak evoked activity of the spinal neurons. The responses observed during the stimulation will be compared to the responses without stimulation. The protocol for magnetic stimulation will be established by Dr. Jerry Jacobson, chairman of Pioneer Services International Ltd. and optimized with the expertise of Dr. Bill Yamanashi, research professor and member of the Scientific Advisory Board for Pioneer Services. Dr. Jacobson added: "We believe this quantitative analysis will provide important insights about effects of Jacobson Resonance field effects on pain and in particular, angina pectoris. We are thankful to have such eminent and visionary experts working with us on this critically important project." Pioneer Services International Ltd. is positioned to be an innovator and leader in the field of bio-medical and bio-electromagnetic technology. For more information please contact: Dr. Frank A.
