Cure Disease: Since coronary heart disease has become a leading cause of death in young and middle-aged men in the United States and since there is no really effective cure disease for it, either surgical or medical, it is essential that the causes of the disease be appraised so that preventive measures can be devised. Studies show that several factors are involved in coronary heart disease, with no single cause being entirely responsible, but the degree of responsibility of each of the many causes is not known.
Thyrotoxic Heart Disease. Thyrotoxicosis is a condition caused by oversecretion by an enlarged thyroid gland; it sometimes affects the functioning of the heart. Exophthalmic goiter causing thyro-toxicosis was responsible for 3% of the 3,000 cardiovascular cases analyzed in New England by T. Duckett Jones and Paul Dudley White in the 1920's. That was before any cure disease for the disease was known. Later, when surgical operations and drug therapy, especially the use of radioactive iodine, were introduced, thyrotoxicosis was quickly treated and cure diseased.
Mycoplasmosis is a respiratory disease caused y the bacteria Mycoplasma gallisepticum. It is Iso known as air sac disease or chronic respira-jry disease. Those affected with the disease may how nasal discharge, watery eyes, and respira-)ry difficulty. This disease is often associated /ith other respiratory diseases. It is transmitted hiefly from infected hens to their chicks through le eggs. The disease can also be transmitted by ontact with infected individuals, but it spreads ery slowly in this manner. The disease can best e controlled by maintaining breeding flocks free f the disease by strict measures of isolation and mitation. Chicks hatched from such flocks can egin life free of the disease.
