Experiments in the Revival of Organisms

[Music] [Music] [Applause] [Music] I [Music] I should like to tell you that I have seen some of the experiments shown in this film actually carried out at the all Russian physiological Congress as you can imagine technique is everything besides such work as you are about to see renko shares the credit for the methods of human blood transfusion which were first developed in the Soviet Union and are now practiced in this country which have saved so many lives during the war what enabled Soviet scientists to solve this problem long ago science established the fact that animal organs and tissues isolated from the whole organism can be maintained in a living state but in order to achieve this special AR official conditions must be created isolated organs can be brought to life even though they've been removed from the animal's corpse sometime after death he has a dog's heart it can function as well in artificial conditions as in a living organism and for this purpose blood is introduced into the cardiac vessels the isolated heart beats just as it did a few hours previously in the living dog the following experiment is conducted on lungs taken from an animal Bellas distend the lungs and fill them with there the Venus blood is forced into the lungs by the action of the pump the dark Venus blood passes through this tube in the lungs it takes up oxygen and becomes arterial blood the isolated lungs breathe producing the same chemical changes as in a living animal an animal's head can also live in the isolated condition here is a plan of the experiment the arterial pump takes arterial blood from the reservoir to the head while the Venus pump drains off the Venus blood the blood is arterialized in the reservoir where there is a steady flow of oxygen the artificial blood circulation ensures the metabolism necessary for the life of the head the isolated head lives on for hours and reacts to external stimuli for the isolated head even reacts to light and to sound the Revival of individual organs enabled scientists to proceed to experiment on Reviving the whole organism the Revival of the whole organism can be achieved with the help of an apparatus called the autoject the auto ejector carries out the functions of the heart and lungs as we know the Heart by its rythmical contractions supplies the body with arterial blood rich in oxygen after losing its oxygen the blood returns to the heart through the veins from then it flows into the lungs when with a fresh supply of oxygen it returns to the heart and then flows into the arteries of the organism the auto ejector works on the same principle the apparatus includes a system of pumps for supplying blood and drawing it off the arterial pump supplies the organism with arterial blood when the blood has given up its oxygen the Venus pump draws it back into the reservoir here just as in the lungs it's enriched with oxygen and returns into the organism the blood passing into the arteries of the body ensures the necessary metabolism in this way the auto ejector can perform the work of both the heart and lungs We Begin The Experiment of Revival the experiment is carried out on a dog a substance which prevents clotting is introduced into the animal's blood the dog is under an anesthetic it doesn't feel pain No Interruption of the animal's normal functions has yet occurred dog reacts to touch it's pupil are Norm a special apparatus the Chima grass registers the breathing and the function of the do dogs heart the pulse and breathing are normal the experiment begins all the blood is drained up through the Ked artery is the heart has stopped this is one of the animals last gasps this is the final bless the dog is dead without operative interference death would be final as the disintegration of the body cells would gradually set in the auto ejector is being attached before starting the Revival the arterial pump is connected with the artery the Venus pump is connected with a ve 10 minutes have elapsed since the animal died the blood removed from the animal is pumped back into its vessels by the auto ejector the auto ejector ensures a normal blood circulation in the organism replacing the action of the Dead heart and LS the artificial blood circulation gradually induces the heart to start beating again the heart's action begins to be normal first side the respiration is gradually restored the dog breathes more normally and evenly the animal's condition approaches normal we can now disconnect the auto ejector and leave the organism of a dog to maintain life with its own resources the dog soon shakes off the effect of the anesthetic the dog is still weak and can't [Music] move [Music] after 10 to 12 Days the dog returns to its normal [Music] state after the experiment dogs live for years they grow they put on weight and have [Music] families for a number of years now three dogs have been under observation in the voles Medical Institute after being survived by artificial blood [Music] circulation this dog bunny was revived in 1939 after having been dead for 8 minutes black ears is The Offspring of revived parents she herself was revived in 1939 after 11 and 1/2 minutes of death NAA was devised in 1938 after 15 minutes of [Music] death these experiments on the Revival of dogs have shown that the process has no harmful effect on the animal organism the question of the Revival of animals is one of the most interesting problems in physiology today experiments on Revival have added to the valuable all of our knowledge of experimental medicine
