Biological Sampling & Physiological Measurement

A rat-friendly modification of the non-invasive tail-cuff to record blood pressure

In animal models, blood pressure measurement methods can be either invasive (direct) or non-invasive (indirect). The non-invasive alternative involves applying a tail-cuff for blood pressure measurement. Current standardized restraint methods involve confining the laboratory animal in plastic chambers, which can...

Refinement of a model of repeated cerebrospinal fluid collection in conscious rats

The cannulation of the cisterna magna in rats for in vivo sampling of cerebrospinal fluid serves as a valuable model for studying the delivery of new drugs into the central nervous system or disease models. It offers the advantages of...

A comparison of various methods of blood sampling in mice and rats: Effects on animal welfare

This study was conducted to investigate the effects of blood sampling on animal welfare in a total of 60 NTac:SD rats and 72 C57BL/6NTac mice of both sexes. Blood was sampled either by sublingual vein puncture, tail vein puncture or...

The gingival vein as a minimally traumatic site for multiple blood sampling in guinea pigs and hamsters

Laboratory animals are still necessary in scientific investigation and vaccine testing, but while novel methodological approaches are not available for their replacement, the search for new, humane, easy, and painless methods is necessary to diminish their stress and pain. When...

Laparoscopic technique for serial collection of para-colonic, left colic, and inferior mesenteric lymph nodes in macaques

Unlike peripheral lymph nodes (PLN), the mesenteric lymph nodes (MLN) draining the gastrointestinal (GI) tract are exposed to microbes and microbial products from the intestines and as such, are immunologically distinct. GI draining (MLN) have also been shown to be...

Measurements of core temperature in spontaneously hypertensive rats by radiotelemetry

Handling and restraint can cause significant increases in core temperature. When SH [spontaneously hypertensive] rats are not stressed or disturbed, their core temperatures are not significantly different from that of normotensive WKY [Wistar-Kyoto] rats.

Cortisol response of female rhesus monkeys to venipuncture in homecage versus venipuncture in restraint apparatus

All subjects were well habituated to blood collection, and it was not necessary to immobilize them; they readily presented a leg for venipuncture. In single monkeys venipunctured in the restraint apparatus, cortisol concentrations were on average 50% higher 15 minutes...

Impact of venipuncture on physiological research conducted in conscious macaques

A survey of 397 publications dealing with macaques was conducted. Stress-sensitive physiological data collected during venipuncture were evaluated in 58 reports. Despite of the fact that venipuncture often is a stressful event for research animals, 81% of the studies did...

Avoiding undue cortisol responses to venipuncture in adult male rhesus macaques

Six adult rhesus males were: a) habituated to actively cooperate during venipuncture away from the homecage in a treatment squeeze cage, and b) trained to actively cooperate during venipuncture in the homecage.The magnitude of cortisol increase was significant when the...
