Preface
Although much has been written about methods for the care and
production of laboratory animals, there has been a lack of compiled in-
formation on the use of animals in various fields of research. In the be-
lief that such compilation would benefit investigators conducting re-
search dependent upon the use of animals, this book was written.
"Methods of Animal Experimentation" provides information on the most
common methods for using animals as tools in the search for new bio-
logical knowledge. The authors of the individual contributions and the
editor believe that the techniques described will facilitate the most
efficient use of research animals and provide guidelines for their utmost
comfort and welfare.
The descriptions of both fundamental and well-developed techniques
of animal experimentation in various research fields should be useful to
graduate students and experienced scientists who must consider varia-
tions in research approaches. The book is a source of information for the
scientist administrator who is frequently confronted with different pro-
posed approaches to biological research projects utilizing animals.
The text is arranged according to specific research methods rather
than to organ system or disease category. This approach gives the reader
a broad view of the techniques involved in specific fields and describes
the range of usefulness of these techniques. This approach also made it
possible to select contributors expert in experimental methods and
equally well qualified in the care of laboratory animals.
The common diseases of laboratory animals are not discussed in the
text unless they are related closely to the experimental methods de-
scribed. Although not intended to be a general guide on conventional
methods of the production, care, and feeding of laboratory animals, the
book thoroughly reviews special animal care associated with each ex-
perimental technique. The book also discusses hazards involved in using
the various experimental techniques and suggests necessary safety pre-
cautions. The reader is referred to W. Lane-Petter's "Animals in Re-
search" (Academic Press, New York, 1963) for basic information on
laboratory animal care and maintenance.
The first five chapters of Volume I describe basic information, meth-
ods, and principles involved in managing animals for experimental pro-
cedures. The remaining chapters in Volume I and those in Volume II
deal with special techniques which have been demonstrated to be dis-
tinct, useful methods for using laboratory animals as a basic biomédical
research tool.

Introduction
Volumes on methodology associated with the basic science disciplines
have become commonplace. It is surprising that the techniques for using
animals in biomédical research have not been previously compiled. This
text will provide a cross section of information dealing with the tech-
niques of a wide variety of experimental procedures.
It is alarming to discover the lack of knowledge of this subject by
many graduate students in the biological sciences. The recent trend in
many disciplines toward studying isolated phenomena is resulting in a
lack of appreciation for the considerable fundamental knowledge which
may be gained by making use of experiments utilizing information from
the "whole animal." Many students in the biological sciences receive all
of their research training using tissue cultures or isolated microorganisms.
No doubt these students will reach a point in their investigations where
it will be essential to test concepts in experimental animals. Hopefully
this text will stimulate incorporation of courses in methods of animal ex-
perimentation into the curricula of these students.
It has become increasingly obvious that ideas for new avenues of re-
search are dependent upon a general knowledge of the experimental
methods that have been used in both related and unrelated research
areas. Many of the so-called "original" investigations have involved
adapting methods used in other types of studies to the individual's
problem. This text will doubtless stimulate new approaches by making
investigators aware of the methods used in other fields.
This text covers a variety of topics by individuals actively using the
techniques they describe. The descriptions of the techniques in any spe-
cific category is not intended to be exhaustive but each has an ample
bibliography and will serve to orient the reader to the pertinent litera-
ture.

I. Introduction
The purpose of this chapter is to present a résumé of the more com-
monly used techniques for the collection and withdrawal of body fluids
and infusion techniques with experimental animals. Through the years
many techniques have been used and described in periodical literature.
It is hoped that this chapter will assimilate much of this data in a readily
accessible form. The reader must be aware, however, that all available
techniques are not discussed.
Much of the material presented will be quite elementary. This is
necessary since this book will be used as a reference guide by some in-
dividuals who have not had previous experience with animal experi-
mentation. Such basic information for these people is invaluable.
ΧΑ11 illustrations for this chapter have been drawn by George Lynch, medical il-
lustrator at Wake Forest College, The Bowman Gray School of Medicine, Winston-
Salem, North Carolina.

II. Collection and Withdrawal of Body Fluids
A. Blood and Lymph Collection
1. The Mouse
a. Blood Collection. The blood volume of a 30-gm mouse is approxi-
mately 2.4 ml. However, one is seldom able to obtain more than approxi-
mately one-half this volume.
Heart puncture. This technique requires that the animal be anes-
thetized. It usually is accomplished by placing the mouse in a jar which
contains cotton saturated with ether and leaving him until his activity
ceases and he breathes with moderately deep and regular respiratory
movements. The animal is then restrained in dorsal recumbency. Figure
1 illustrates a board with clips fastened at the four corners which can be
attached to the animal's legs and tension can be applied. A 1- or 2-ml
syringe with a 25- to 27-gauge, %- to 1-inch needle is used. The thorax
is swabbed with disinfectant and the apex beat of the heart is palpated
with the index finger. This is located immediately anterior to the xiphoid
cartilage. The needle is introduced into the area of the heart and aspira-
tion applied. This is not an easy technique, and the old adage "practice
makes perfect" applies.
Tail venipuncture. This technique can be applied without the use of
anesthesia providing the mouse is restrained. However, the technique is
more easily accomplished if anesthesia is used. Place the mouse on a
flat surface under a bright light, preferably of the white "spotlight vari-
ety, and grasp the tail between the thumb and the index finger. Swab
the tail first with xylol, follow with disinfectant, and dry with a sponge. A
1- or 2-ml syringe with a 25- to 27-gauge, %- to 1-inch needle is used.
The veins are visualized laterally and dor sally on the tail. The needle is
introduced near the distal portion of the tail with the bevel up. This al-
lows one to observe directly as the needle enters the vein, and gentle
aspiration can be applied. If subcutaneous hemorrhage occurs, it is
better to move the site anteriorly along the vein. This is a very difficult
technique and requires much practice to gain proficiency.
Jugular venipuncture. Kassel and Levitan (1953) state that samples
may be drawn repeatedly from this site for several weeks if necessary.
Briefly, the mouse is held by the skin at the back of the neck and the
head is extended by fastening gauze over its upper incisors and hold-
ing this between the fingers of the left hand. The hair of the neck and
upper thorax is removed and both jugulars are easily seen. A 26-gauge
needle is used to enter the distended vessel. It is stated that weanling
mice and larger may be bled in this manner.
