The present study was a protocol for investigation of the effect of acetaminophen (i.p.) on pain induced by electrical stimulation. We used tail shock vocalization (TSV) test for measurement of the pain. In this test, the animals were restrained and stimulated by two electrode implanted on the middle of the animal’s tail. The latency from stimulation of the tail till vocalization of the animal ...

The effects of chronic morphine administration on the development of long-term potentiation (LTP) were investigated at the Schaffer collateral-CA1 pyramidal cell synapses of the rat hippocampal slices using primed-bursts tetanic stimulation. Significant enhancement of orthodromic population spike (OPS) was found for all stimulus intensities after tetanic stimulation. OPS enhancement was greates...

Introduction: Brain injury induced coma is the main cause of hospitalization of patients in the intensive care unit (ICU) and their consequent stressful physiological complications, which can be prevented using sensory stimulation as a therapeutic method. Nevertheless, identifying and using the optimal sensory stimulation program is crucial. Objective: The present study was conducted to de...

Background: Premature infants undergo a lot of stressors during treatment procedures in the neonatal intensive care units which causes significant physiological changes in these neonates. Multi-sensory stimulation is a broad category of interventions designed to improve the evolutionary and physiological outcomes of premature infants hospitalized in the neonatal intensive care unit to minimize ...

Background: Many physical and mechanical phenomena occur during the acupuncture and tuina regime, and pressure is one of the most basic mechanical phenomena. Objectives: To understand the cellular bio-physical mechanism of basic mechanical stimulation via acupuncture and tuina by investigating the effect of different in vitro pressures on the cel...

There are some conflicts about constancy of conduction velocity (CV) in a given tract of nervous system. By recording excitatory postsynaptic currents (EPSC) in layer IV of the somatosensory cortex we tried to clear changes in CV of thalamocortical tract of mice aged 3 to 50 days old. Field potentials and EPSC were recorded in the layer IV by stimulation of ventrobasal nucleus of thalamus (VB) ...

Background This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MaterialsAndMethods In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with human chorionic gonadotropin (HCG) on the 4th ...
