Biological Sampling & Physiological Measurement

Chronic monitoring of cardiovascular function in the conscious guinea pig using radio-telemetry

An implantable radio-telemetry device for chronic monitoring of arterial pressure and heart rate in the conscious guinea pig was validated against measurements using an exteriorized, indwelling catheter. There were no significant differences between simultaneous measurements in animals instrumented with both...

Monitoring female reproductive function by measurement of fecal estrogen and progesterone metabolites in the white-faced saki (Pithecia pithecia)

First morning void urine was collected directly in a polypropylene container hand-held under the female subject. A second container was held under the female to collect fecal material. [The group-housed] females urinated and defecated within 5-20 min. Following sample collection,...

Circadian and short-term variabilities in blood pressure and heart rate measured by telemety in rabbits and rats

Blood pressure (BP) and heart rate (HR) were measured by telemetry in conscious unrestrained rabbits to clarify the profile of their variabilities. The variabilities were assessed for two periods, 24 h (circadian rhythm) and 1 h (short-term variability), and compared...

Influences of blood sampling procedures on basal hypothalamic-pituitary-adrenal hormone levels and leukocyte values in rhesus macaques (Macaca mulatta)

Differences in housing location and the amount of room disturbance associated with blood sampling have a significant impact on cell counts, but not on ACTH or cortisol levels. We believe that the critical factor that explains our housing location results...

Refining the blood collection procedure for macaques

Training protocol is described. These findings lead to the conclusion that training nonhuman primates to cooperate during venipuncture in their familiar home environment offers a methodological refinement by eliminating significant cortisol responses.

Training nonhuman primates to cooperate during handling procedures: A review

Twenty-six reports provide detailed information of how primates can be trained to voluntarily cooperate - rather than resist - during blood collection, injection, topical drug application, blood pressure measurement, urine collection, and capture.

Training and remote monitoring of cardiovascular parameters in non-human primates

The use of "pre-invasive" implantable radio telemetry has revolutionized the collection of physiological data under stress-free conditions. It is now possible to measure accurately 'normal' baseline data of haemodynamic and electrical parameters in conscious and unrestrained monkeys. The use of...

Behavior and salivary cortisol in gorillas housed in an all male group

Tomorrow’s animal management today – semen collection in gorillas using behavioral training

Three male gorillas were trained to provide semen samples and allow a physical examination. Training was based on a standard training method - food rewards and verbal praise.

Collecting blood of macaques: An often overlooked variable in biomedical research

The findings of this survey suggest that many investigators do not recognize that the traditional manner of collecting blood can introduce uncontrolled stress variables into research findings, leading to increased data variability and therefore increasing the number of experimental animals...
