3
00:00:55,99 --> 00:00:57,12
I should like to tell you

4
00:00:57,12 --> 00:01:03,42
that I've seen some of the experiments
shown in this film actually carried out

5
00:01:04,12 --> 00:01:10,84
at the all-Russian physiological
congress. As you can imagine, technique is

6
00:01:10,84 --> 00:01:11,57
everything.

7
00:01:12,88 --> 00:01:18,86
Besides such work as you're about to
see, Brukhonenko shares the credit for

8
00:01:18,86 --> 00:01:24,36
the methods of human blood transfusions
which were first developed in the Soviet Union

10
00:01:25,70 --> 00:01:31,52
and are now practiced in this country which
has saved so many lives during the war.

11
00:01:31,53 --> 00:01:36,91
What enabled Soviet
scientists to solve this problem?

12
00:01:38,86 --> 00:01:41,25
Long ago, scientists established the fact

13
00:01:41,25 --> 00:01:46,96
that animals organs and tissues isolated from the
whole organism can and did maintain a living

14
00:01:46,96 --> 00:01:50,24
state. But in order to achieve this,

15
00:01:50,47 --> 00:01:53,39
special artificial
conditions must be created.

17
00:02:08,62 --> 00:02:11,30
Isolated organs can be brought to life

18
00:02:11,60 --> 00:02:17,23
even though they've been removed from the
animal's corpse sometime after death. Here's a

19
00:02:17,23 --> 00:02:18,06
dog's heart.

20
00:02:26,23 --> 00:02:29,59
It can function as well in artificial
conditions as in a living organism.

21
00:02:30,58 --> 00:02:31,22
And for this purpose,

22
00:02:31,48 --> 00:02:37,77
blood is introduced into the cardiac vessels.
The isolated heart beat just as it

23
00:02:37,77 --> 00:02:42,90
did a few hours previously in
the living dog.

24
00:03:05,86 --> 00:03:09,02
The following experiment is conducted
on lungs taken from an animal.

25
00:03:15,91 --> 00:03:20,67
Bellows expand the lungs

26
00:03:20,67 --> 00:03:23,19
and fill them with air.

27
00:03:36,71 --> 00:03:39,93
The venous blood is forced into the
lungs by the action of the pump.

28
00:03:43,77 --> 00:03:47,77
The dog's venous blood passes
through this tube.

29
00:03:53,49 --> 00:03:59,93
In the lungs, it takes up oxygen and
becomes arterial blood.

30
00:04:09,87 --> 00:04:14,79
The isolated lungs breathe, producing the same
chemical changes as in a living animal.

31
00:04:26,88 --> 00:04:30,40
An animal's head can also live
in the isolated condition.

32
00:04:31,70 --> 00:04:33,21
Here is the plan of the experiment:

33
00:04:39,52 --> 00:04:40,53
The arterial pump

34
00:04:40,68 --> 00:04:45,18
takes arterial blood from the reservoir
to the head while the venous pump

35
00:04:45,37 --> 00:04:50,47
drains off the venous blood. The blood
is arterialized in the reservoir

36
00:04:51,05 --> 00:04:53,34
where there is a steady flow of oxygen.

38
00:05:24,03 --> 00:05:25,61
The artificial blood circulation

39
00:05:25,61 --> 00:05:29,22
ensures the metabolism necessary
for the life of the head.

40
00:05:37,95 --> 00:05:42,74
The isolated head lives on for hours
and reacts to external stimuli.

44
00:06:25,97 --> 00:06:32,53
The isolated head even reacts
to light and sound.

45
00:06:50,67 --> 00:06:57,52
The revival of individual
organs enabled scientists

46
00:06:57,52 --> 00:07:01,47
to proceed to experiment on
reviving the whole organism.

47
00:07:02,34 --> 00:07:08,62
The revival of the whole organism can
be achieved with the help of an apparatus

48
00:07:08,62 --> 00:07:10,84
called the Auto-Injector(?).

49
00:07:22,82 --> 00:07:26,68
The Auto-Injector(?) carries out the
functions of the heart and lungs.

50
00:07:28,11 --> 00:07:35,09
As we know,

51
00:07:35,09 --> 00:07:40,00
the heart's rhythmical contractions
supplies the body with arterial blood,

52
00:07:40,00 --> 00:07:41,58
rich in oxygen.

54
00:07:49,99 --> 00:07:54,08
After losing its oxygen, the blood returns
to the heart through the veins. 

55
00:07:58,87 --> 00:07:59,13
From then,

56
00:08:00,00 --> 00:08:05,89
it flows into the lungs. Whence with a fresh
supply of oxygen, it returns to the heart

57
00:08:06,69 --> 00:08:08,97
and then spills into the
arteries of the organ.

58
00:08:22,27 --> 00:08:28,47
The Auto-Injector(?) works on the same principle.
The apparatus includes a system of pumps

59
00:08:28,47 --> 00:08:30,69
for supply of blood and drawing it out.

60
00:08:45,21 --> 00:08:51,58
The arterial pump
supplies the organism with

61
00:08:51,58 --> 00:08:52,25
arterial blood.

62
00:08:54,21 --> 00:08:58,81
when the blood has given up its oxygen, 
the venous pump draws it back into the

63
00:08:58,81 --> 00:09:04,21
reservoir. Here, just as in the
lungs, it's enriched with oxygen

64
00:09:04,21 --> 00:09:09,07
and returns into the organism. The blood
passing into the arteries of the body

65
00:09:09,07 --> 00:09:11,26
ensures the necessary metabolism.

66
00:09:12,17 --> 00:09:19,12
In this way, the Auto-Injector(?)
can perform the work of both the

67
00:09:19,12 --> 00:09:21,68
heart and lungs.

68
00:09:38,93 --> 00:09:44,02
We begin the experiment of revival. The
experiment is carried out on a dog.

69
00:10:00,00 --> 00:10:06,51
A substance which
prevents clotting is

70
00:10:06,51 --> 00:10:11,19
introduced into the animal's blood.
The dog is under an anesthetic.

71
00:10:11,21 --> 00:10:13,42
It doesn't feel pain.

72
00:10:14,77 --> 00:10:17,90
No interruption of the animal's
normal functions has yet occurred. 

73
00:10:28,44 --> 00:10:32,01
The dog reacts the touch,
its pupils are normal.

74
00:10:45,66 --> 00:10:49,30
A special apparatus, the chemo-graph(?), 
registers the breathing

75
00:10:49,30 --> 00:10:55,37
and the function of the
dog's heart.

76
00:10:55,37 --> 00:10:56,32
The pulse and breathing are normal.

78
00:11:07,04 --> 00:11:12,71
The experiment begins. All the blood is 
drained out through the carotid(?) artery.

86
00:12:00,00 --> 00:12:04,83
The heart has stopped.

88
00:12:19,52 --> 00:12:24,17
This is one of the animal's last gasps.

89
00:12:30,18 --> 00:12:31,32
This is the final breath.

90
00:12:46,01 --> 00:12:47,24
The dog is dead.

92
00:13:05,66 --> 00:13:08,93
Without operated interference,
deaths would be final

93
00:13:09,31 --> 00:13:16,30
as with disintegration of the body's 
cells would gradually set in.

94
00:13:16,31 --> 00:13:19,37
The Auto-Ejector(?) is being attached 
before starting a revival.

95
00:13:21,10 --> 00:13:23,46
The arterial pump is connected 
with the artery.

96
00:13:34,02 --> 00:13:36,26
The venous pump is connected with a vein.

97
00:14:00,00 --> 00:14:08,09
Ten minutes have elapsed
since the animal died.

98
00:14:10,76 --> 00:14:16,68
The blood removed from the animal is pumped
back into its vessels by the Auto-Ejector(?).

99
00:14:21,17 --> 00:14:26,89
The Auto-Ejector(?) ensures a normal blood
circulation in the organism, replacing the 

100
00:14:26,89 --> 00:14:27,28
action of the dead heart and lungs.

102
00:15:00,70 --> 00:15:28,40
The artificial blood circulation gradually
induces the heart to start beating again.

103
00:15:32,38 --> 00:15:59,45
Heart action begins to be normal.
First sigh.

104
00:16:03,15 --> 00:16:17,38
Respiration is gradually restored.

105
00:16:25,24 --> 00:16:27,00
The dog breathes more normally
and evenly.

106
00:16:27,00 --> 00:16:35,05
An animal's condition
which is normal.

107
00:16:35,06 --> 00:16:37,26
We can now disconnect the Auto-Ejector

108
00:16:37,26 --> 00:16:53,96
and leave the organism of a dog to
maintain life with its own resources.

109
00:16:56,51 --> 00:17:03,13
The dogs soon shakes off the
effects of the anesthetic.

110
00:17:03,14 --> 00:17:04,79
The dog is still weak and can't move.

111
00:17:38,87 --> 00:17:42,73
After ten to twelve days, the dog
returns to its normal state.

112
00:17:50,79 --> 00:17:55,93
After the experiment, (the) dogs lived for
years, they grow, they put on weight,

113
00:17:55,93 --> 00:17:57,23
and have families.

114
00:18:12,15 --> 00:18:13,97
For a number of years now,

115
00:18:13,99 --> 00:18:19,79
three dogs have been under observation
in the Polonaise Medical Institute after

116
00:18:19,80 --> 00:18:30,12
being revived by 
artificial blood circulation.

117
00:18:30,14 --> 00:18:34,70
This dog, Bani(?), was revived 
in 1939

118
00:18:34,72 --> 00:18:37,45
after having been dead for eight minutes.

119
00:18:38,35 --> 00:18:44,36
Black Ears is the offspring of revived
parents. She, herself, was revived in

120
00:18:44,36 --> 00:18:48,56
1939 after eleven and a half minutes
of death.

121
00:18:48,58 --> 00:18:52,05
Naida was revived in 1938

122
00:18:52,38 --> 00:18:55,71
after fifteen minutes of death.

123
00:19:01,72 --> 00:19:04,05
These experiments, on the revival of dogs,

124
00:19:04,05 --> 00:19:08,39
has shown that the process has no harmful
effects on the animal organism.

125
00:19:08,39 --> 00:19:14,03
The question of the revival of animals
is one of the most interesting problems

126
00:19:14,03 --> 00:19:15,22
in physiology to day.

127
00:19:16,43 --> 00:19:21,02
Experiments on revival have added to the
valuable store of our knowledge of

128
00:19:21,02 --> 00:19:22,08
experimental medicine.
