The effect of harp music on heart rate, mean blood pressure, respiratory rate, and body temperature in the African green monkey.
ABSTRACT The effectiveness of recorded harp music as a tool for relaxation for non-human primates is explored in this study.
Konigsberg Instruments Model T27F-1B cardiovascular telemetry devices were implanted into nine African green monkeys (Chlorocebus aethiops). After post-surgical recovery, animals were exposed to recorded harp music. Telemetry data were collected on heart rate, mean blood pressure, respiratory rate, and body temperature for a 30-minute baseline period before music exposure; a 90-minute period of music exposure; and a 90-minute post-exposure period, where no music was played.
No statistical differences were noted in heart rate, mean blood pressure, respiratory rate, and body temperature between pre-exposure, exposure, and post-exposure periods.
The lack of response in these African green monkeys may be attributable to their generally calm demeanor in captivity; experiments with a more excitable species such as the rhesus macaque might demonstrate a significant relaxation response to music.

ABSTRACT: INTRODUCTION: The accurate assessment of blood pressure is often a key component of preclinical cardiovascular disease/efficacy models and of screening models used to determine the effects of test agents on cardiovascular physiology. Of the many methods utilized in large animals, telemetry is becoming more widely used throughout preclinical testing, and non-human primates are playing an ever increasing role as a large animal model to evaluate the cardiovascular effect of novel test agents. Therefore, we sought to characterize pressure transducer drift of a telemetry implant in primates over an extended duration. METHODS: We instrumented ten rhesus monkeys with a Konigsberg T27F implant and a chronic indwelling arterial catheter and cross calibrated the diastolic pressure recorded by the implant to the diastolic pressure that was simultaneously recorded through the arterial catheter using a calibrated external transducer/amplifier system. RESULTS: While all implanted pressure transducers experienced driJournal of pharmacological and toxicological methods 01/2009; 59(1):35-38. · 2.32 Impact Factor
Conference Paper: Seasonal variations of agricultural fields in multifrequency SAR images[Show abstract] [Hide abstract]
ABSTRACT: From May 11 to July 31, 1992 the CLoud Experiment OberPfaffenhofen and TRAnsports (CLEOPATRA) took place as a field experiment contribution to the global energy and water cycle experiment (GEWEX/IGBP). The DLR Institute of Radio frequency technology participated with its experimental SAR system (E-SAR) in X-, C-, and L-band, HH and VV polarisations to investigate microwave backscattering mechanisms of agricultural crop types in dependence of multi-temporal ground truth observations during the growing season. The first two flying dates are compared and the differences for the beginning of the growing season investigatedGeoscience and Remote Sensing Symposium, 1993. IGARSS '93.

ABSTRACT: In this study, 27 young and healthy subjects was listening to the classical and Turkish music samples which are believed to changeable the subject's emotional state. Their effects on autonomic nervous system (ANS) are investigated by using the heart rate variability (HRV) analysis which is accepted as a non-invasive indicator of ANS. The electrocardiogram (ECG) and respiration records were made before and during the listening music samples. Heart rate variability (HRV) signals are obtained form records and power spectral densities (PSD) of HRV are estimated. According to the results of calculated parameters, during the listening to classical music samples some statistically significant changes were occurred in sympathetic and parasympathetic activities of ANS. Turkish music samples were not causes significant differences on the ANS related HRV parameters.01/2009;
