An Epidemiological Expedition into the Interior of Africa In the early 1950s Dr. Telford H. Work and Dr. Richard Moreland Taylor traveled to the Sudan to study an outbreak of yellow fever. Flying to Khartoum, they took their equipment by train to El Obeid, and by jeep to the Nuba Mountains (spanning the southern part of the present-day post-partition Sudan and the northern part of South Sudan). Accompanied by Dr.

The work and patient population of the USPHS hospitals is outlined. Dr. John J. Walsh, director of research at the Seamen's Memorial Laboratory in New Orleans gives a report of the research activities carried out at the Laboratory. These include research in parasitic infections, in regional perfusion in the treatment of malignancies, in the dilated heart, in endoplasmic cellular membranes, in drug action at the basic macromolecular level, and in the effect of drugs on the force of the contraction of the heart muscle.

In this film, a narrator discusses with multiple visual aids the dangers of smoking. He first compares smoking cigarettes to chimneys, explaining the natural processes of the lungs and how cigarettes alter them, using a simplified lung diagram. The film shows several clips of men who have been handicapped as a result of smoking. The narrator then explains a smoking machine, which emulates human smoking and collects cigarette tar in glass bottles. Jars of tar in increasing sizes are shown to represent tar intake over time by smokers.

The mode of transmission of hereditary materials which are responsible for the inherited characteristics of all plants and animals is presented. Live action and animation are used to demonstrate what happens when the egg and sperm of red-coated and white-coated cattle meet to form the zygote and when mitosis occurs. Over animation superimposed on live shots of the resulting roan calf, the narrator explains how both sets of genes influence the color of this animal.

This program discusses the preventive, diagnostic and therapeutic measures indicated for lung cancer. The program notes that pre-cancerous lesions from smoking may be reversible and that periodic chest x-rays should be used as the primary diagnostic tool. Such pathologic conditions as the thickening of the bronchial epithelium basal cells with atypical nuclei are described through microscopic views. Radiographs and drawings of several clinical cases illustrate the inoperability of lesions due to their location.

In this film, the elementary principles of first aid for soldiers in the field are presented. The emphasis is on what the soldier should do before medical help arrives. He is shown how to put everyday objects and personal items to good use in emergency situations. The film is narrated over footage of soldiers in the field.

This film starts with a look at the cultivation of tobacco and its role in the economy, and moves on to an examination of the many substances found in cigarettes, how those substances are transformed by burning, and the harmful effect of smoking on the body. Effects on the nervous, cardiac, and respiratory systems are described and shown with animated sequences. Animal experiments that illustrate the physiological impact of nicotine, tar, and other substances are shown.

This film shows an operation performed on a woman pregnant with triplets at Hollywood Presbyterian Hospital in Los Angeles, California. One of the fetuses has died prior to birth. Doctors are shown scrubbing in preparation for surgery, then performing a laparotomy for delivery. Afterwards, the procedure for restoring the patient’s abdomen is shown. The stillborn fetus is examined, and a diagnosis is made of an interstitio-isthmal pregnancy.

This film features three elderly men, Bill, a former soldier, Frank, a former construction worker, and Harry, a former farmer, all of whom now have emphysema. An interviewer visits each man to ask about his experiences with and thoughts about the disease, starting with Bill. Bill's wife laments that he has grown very weak and can now do nothing recreational except read and weave. He is a schoolteacher, but he spends almost all of his free time in bed. Bill admits that he feels judged by people in public and is embarrassed about his condition.

This cartoon features a main character named George who finds himself feeling old, achy, and exhausted. He falls down, drops things often, and is unable to keep up with his family. George's wife suggests that he see a doctor, and he reluctantly goes. He is diagnosed with arthritis. The doctor uses scientific terminology that George cannot understand, and he feels defeated by the situation. His friends suggest a number of possible remedies for his arthritis, none of which sound promising to George. His condition worsens, and he again grudgingly visits the doctor.

This film describes cancers of the mouth, lip, throat, neck, eye, nose, and skin in both early and advanced, severe stages. It discusses the need for early diagnosis and treatment, probable causes of such cancers, the need for research, and the modern facilities available at the Veterans Hospital in Hines, Illinois. Produced by the U.S. Veterans Administration.

This film shows experiments conducted during World War II on behalf of the National Research Council to better understand decompression sickness. Dr. Edmund Newton Harvey was best known for his research on bioluminescence, but he also conducted applied research in areas such as wound ballistics and aviation physiology. In these experiments, Harvey explores the phenomenon of bubble formation in blood and tissue.

This film presents the basic principles of first aid, the circulatory system, improvised tourniquets, use of bandages, treatment of shock, burns, artificial respiration, and splints. Produced by the United States Public Health Service;.

This film shows, by means of cinefluorography, the normal lungs, bronchiogenic carcinoma, carcinoma with abscess formation, metastases of seminoma, and metastases of sarcoma with bilateral spontaneous pneumothorax.

This program presents a case of a thirty year old man with Marfan's syndrome to illustrate the surgical procedure for correcting a dissecting aneurysm of the ascending aorta with aortic valvular insufficiency. The patient's preoperative physical findings and aortograms which indicate the need for this surgery are presented. In this instance the entire ascending portion of the aorta is involved. The transverse and descending aorta are not considered unusual.
