EMBRYO DEVELOPMENT: ACCIDENTS SOMETIMES HAPPEN
During the third week of the life of the embryo, the heart starts to develop. It is at first only an enlargement of blood vessels which soon begins to beat and move the blood along throughout the whole body. The heart gradually changes into the shape that it holds after birth even though no blood goes from it to the lungs until the child is born and begins to breathe.
Meanwhile the blood completes its circuit for, from the vessel which normally should take it to the lungs, a broad short tube called the ductus arteriosus side-tracks it back to the main great artery, the aorta. When the child is delivered, with its first cry or gasp the lungs fill with air. After this the ductus normally closes off. Occasionally it does not; then some of the blood, which should go to the lungs to receive its oxygen, sticks to its old route by what we now call the patent (that is, open) ductus arteriosus. You can see that it is a handicap to the child to have a considerable portion of its blood un-freshened by oxygen.
Such persons are weak and physically inefficient. Sooner or later infection of the lining of this blood vessel sets in and death is likely to occur by the thirties at the latest. One of the most brilliant developments of recent surgery is the surgical closing off of the ductus, devised by Dr. Robert Gross, of Boston. When this is done, the blood then has to follow its normal course.
For many reasons development does not always go smoothly and according to schedule. It is thought that pregnancy not infrequently occurs and is then interrupted at such an early stage that it is not even suspected. Biologists with carefully conducted experiments on animals can injure embryos and cause them to develop in abnormal forms. From this it is reasoned that accidents to human embryos may cause abnormal forms.
It is usual for a human female to give off one ovum at a time. Occasionally at an early stage something causes the embryo to divide into two individuals, each of which develops normally. Then we have like, or identical, twins. They are always of the same sex and look alike. This is very different from the case where the mother gives off two ova at a time. These twins are not necessarily at all alike.
Unfortunately, whatever happens to the early embryo may occasionally result not in complete division and twins, but in partial division which may give such abnormalities as Siamese twins. In the past such occurrences seemed to be controlled by chance alone. Apparently there was no rhyme or reason in the whole matter. In recent years we are beginning to get some evidence of cause and effect.
Possibly, the first definite light on this came from Australia. About a dozen years ago a physician there studied a series of cases of congenital cataract which occurred in a period of about a year. A cataract is a change in the lens of the eye which obstructs the rays of light. This occurred to the babies at birth or soon after. A short while previously there had been an epidemic of rubella, or German measles. Investigation showed that some expectant mothers who contracted rubella during the first three months of pregnancy later had babies with congenital abnormal changes, usually cataracts.
This discovery started a series of investigations on animals. It has been found that there are numerous ways by which the embryo can be injured with resulting deformity. The stage of uterine life at which the injury occurs seems to determine the type of congenital defect.
The above tale may seem at first rather depressing, but further consideration will show a decidedly hopeful aspect. When we are in the dark as to the cause of trouble we know not what to do to avoid it. Once the cause is determined we may proceed to campaign hopefully against it. Medical history is full of evidence to this effect. In my youth “typhoid lit its dusky flame” every fall. But by that time we had learned the cause, and although we had no drug to combat it, the added knowledge as to its manner of spread and our ability to recognize it early soon enabled us to get almost complete control over it.
Today it is hard to find a case for medical students to observe. Our knowledge of vitamins has made it possible to avoid rickets, scurvy, pernicious anemia, and other deficiency diseases.
So it should be a cheering thought that the defective development of a child in the womb is not controlled by mere chance. There is always a definite cause. Our knowledge of these causes is increasing rapidly, and already we have some control over them. Better medicine, better obstetrics, and the education of prospective parents are making childbirth an even more happy prospect.
