﻿INSTITUTE OF PHYSIOLOGY
183
maximum number of students who can work simultaneously in this laboratory is forty.
The second floor of the southeast wing is occupied by the operation department. This consists of an anteroom for cleaning and narcotizing the experimental animals, the operation room proper (Fig. 9), and a sterilization room. The latter is provided with an autoclave, a dry sterilizing oven, and an oven heated by steam for the sterilization of instruments. The sterilization room is also provided with wash-basins for the operators.
The fitting up of the operation room corresponds to that of any of the larger surgical services. However, the operating table is constructed with a view to its particular purpose and its surface can be heated by means of electricity. In addition the operation room is fitted up with the ordinary electric installations used in most laboratories.
Besides the operation department, the second floor contains two laboratories, one of which is devoted to histological research, while the other, which is provided with a shaft driven by motor and the usual modern laboratory devices, is mainly used for metabolic research.
The department is provided with stables large enough to hold large experimental animals such as horses. In connection with the stables are pens for dogs and rabbits.
Professor V. Henriques is director of the Institute of Medical Physiology.
INSTITUTE OF BIOCHEMISTRY
The Institute of Biochemistry teaches biochemistry to the medical students who study physiology and anatomy simultaneously. The total number at any time is about 360.
The permanent staff consists of the professor, two scientific assistants, one of whom acts also as a clerk, and one attendant.
The annual official budget available for laboratory purposes is 6,400 kroner.
There are five rooms in the basement; namely, the mechanic’s and the joiner’s workshops, a room for the large centrifuge, and two preparation rooms. One of the preparation rooms is designated for the preparation of experiments to be demonstrated during the lectures; it is directly connected with the large lecture-room and the table on which the experimental fittings, etc. are placed can easily be rolled into the lecture-room. The other preparation room, which corresponds to three units, is designated for chemical work on a large scale.
The main biochemical laboratory is on the second floor. There is a large teaching laboratory with working places for forty students (Fig. 6). As the course is given four times a year 160 students can be accommo-
dated annually. Each working place is provided with a set of chemicals, water, gas, and a sink. On tables along the window fronts special experiments can be performed.
In connection with the large teaching laboratory there is a weighing room and a dark room for the students; further a preparation room, where the preparatory work for the course is carried out.
A smaller laboratory with room for twelve students only, is used for advanced and special courses.
The rest of the rooms are equipped for research and are used by the staff and guests. They are furnished in accordance with the general design of the whole institute, special installation and special fittings being employed as an exception. The majority of the larger rooms have steam pipes which have proved very useful.
Among the rooms equipped for special purposes, such as weighing room, Kjeldahl and ILS rooms, should be mentioned a refrigerating room fitted up like a small laboratory, with water, gas, compressed air, etc., so that one is able to carry out the entire experimental technic, centrifugations, etc., at a temperature of about 0°. Corresponding to this room, there is a larger one which can be adjusted to a constant, high temperature (37° C.).
Finally, there is a large dark room for polarization, colorimetry, etc.
To the Institute belong stables for animals; for the animals under experimentation, there are also rooms in the laboratory proper, and the large flat roof of the lecture-theater, which is directly connected with the rooms of the biochemical institute, is employed for animals under experimentation when it is desired to keep them in the open air.
Professor R. Ege is director of the Institute of Biochemistry.
LABORATORY OF BIOPHYSICS
The purpose of the Laboratory of Biophysics of the University of Copenhagen is to teach physics to students of medicine and to some students of natural history. The present enrolment is about 220 students of medicine and twenty students of natural history each year. The special facilities of the laboratory are also used for the teaching of advanced students of physics (four to five per year).
For research purposes the laboratory is equipped for most kinds of biophysical work, especially for work concerning x-rays, radioactive substances, and light. The laboratory is in close cooperation wdth the Finsen Institute of Medical Light Treatment and the Radium Institute of Copenhagen and thus has access to considerable quantities of radium emanation.
The laboratory is cooperating with the Danish x-ray therapists to secure the use of the international x-ray
