Multifactorial analysis of human blood cell responses to clinical total body irradiation
Multiple regression analysis techniques are used to study the effects of therapeutic radiation exposure, number of fractions, and time on such quantal responses as tumor control and skin injury. The potential of these methods for the analysis of human blood cell responses is demonstrated and estimates are given of the effects of total amount of exposure and time of protraction in determining the minimum white blood cell concentration observed after exposure of patients from four disease groups.

Dosimetry for radiobiological studies of the human hematopoietic system
A system for estimating individual bone marrow doses in therapeutic radiation exposures of leukemia patients was studied. These measurements are used to make dose response correlations and to study the effect of dose protraction on peripheral blood cell levels. Three irradiators designed to produce a uniform field of high energy gamma radiation for total body exposures of large animals and man are also used for radiobiological studies.

The Value of Continued Followup in a Preventive Medicine Program
Continued monitoring of hypertension and cholesterol levels in NASA employees by regularly scheduled medical examinations prevents an increase in employee disability and cardiovascular mortality rates. Adequate therapeutic control for younger hypertensive employees is demonstrated by records on mortality and heart diseases over a period of 28 months. It confirmed the importance of systolic blood pressure as diagnostic tool for the inherent risk factor. The prevalence of additional coronary risk factors among employees with hypercholesterolemia is considerably less than in employees with hypertension.

Laboratory Aspects of Blood Lipids
Classification of blood hyperlipemias by electrophoresis or ultracentrifugation according to density fraction is described and therapeutic measures for humans with hyperlipoproteinemia are outlined. The statistically significant relationship between high serum cholesterol levels and incidence of coronary disease prescribes restricted caloric intake or physical exercise to burn excess calories as preventive measures.

The Management of NASA Employee Health Problem; Status 1971
A system for assessing employee health problems is introduced. The automated billing system is based on an input format including cost of medical services by user and measures in dollars, that portion of resources spent on preventive techniques versus therapeutic techniques. The system is capable of printing long term medical histories of any employee.

Biomedical support systems
Biomedical support hardware for SMEAT consisted basically of two systems, the inflight medical support system, and the operational bioinstrumentation system. The former is essentially a diagnostic and therapeutic kit; the latter is a belt equipped with sensors worn by the crewman to permit monitoring of his vital signs. Special attention was given during to the use and verification of the items in the systems so that changes required in the equipment could be pinpointed and effected prior to the Skylab mission. During the in-chamber testing, evaluations were made of the effectiveness of the proposed microbiology procedures, techniques, equipment, and the stability of media and reagents over the extended period of storage.

Treatment of the external epicondylitis of the humerus with a magnetic field
The therapeutic effect of a constant and varying magnetic field on epicondylitis of the humerus is studied on ninety patients. Good results are obtained from the treatment (recovery of 80%, considerable improvement in 14.5%). The method is recommended for clinical application.

Automated mass spectrometer/analysis system: A concept
System performs rapid multiple analyses of entire compound classes or individual compounds on small amounts of sample and reagent. Method will allow screening of large populations for metabolic disorders and establishment of effective-but-safe levels of therapeutic drugs in body fluids and tissues.

Experimental-clinical validation of the use of amitetravit, ATP and autologous bone marrow in radiation injuries caused by prolonged radiation
Experimental clinical studies show that early pathogenetic treatment against the effects of prolonged radiation includes amitetravit as a means of increasing natural radio resistance, ATP as protective therapeutic agent, and automyelotransplantation for early pathogenetic treatment. The high effectiveness of the combined use of ATP and amitetravit in tests on dogs indicates an ability to prevent primary damages to genetic structures and accelerated processes of reparation in the first stages of radiopathological processes.

HEW and the neurologically handicapped
Some of the neurological disorders and therapeutic devices are considered with which the Department of Health, Education, and Welfare (HEW) is most concerned. The organization of the Department, because it is a rather complex one with many different agencies involved, is also described.

Exoskeletal technology
Possible applications are considered of a master-sleeve teleoperator arm system, developed in exoskeletal space suit technology, as therapeutic aid, orthotic device, or for therapy on patients with neurological disorders.

Biological rhythms
An overview is given of basic features of biological rhythms. The classification of periodic behavior of physical and psychological characteristics as circadian, circannual, diurnal, and ultradian is discussed, and the notion of relativistic time as it applies in biology is examined. Special attention is given to circadian rhythms which are dependent on the adrenocortical cycle. The need for adequate understanding of circadian variations in the basic physiological indicators of an individual (heart rate, body temperature, systolic and diastolic blood pressure, etc.) to ensure the effectiveness of prophylactic and therapeutic measures is stressed.

Computer analysis of femoral angiograms for evaluation of atherosclerosis in post-infarct males-clinical correlates
Femoral artery atheromatous lesions were studied and their changes as a measure of therapeutic effectiveness were assessed. The incidence of coronary risk factors in 100 patients was determined. Abnormal cholesterol was present in 42 percent, abnormal triglycerides in 66 percent, abnormal intravenous glucose tolerance test in 52 percent, judged from a K value of .9 or less by the technique of Wahlbert. A history of high blood pressure was present in 32 percent. Smoking was one of the most common factors.

In-flight medical support system
The In-flight Medical Support System for Skylab was designed to provide the onboard Crew Physician or Scientist Pilot (or other crewmember if the Scientist Pilot was unable to act) with information adequate to make diagnostic assessment of those injuries or illnesses most likely to occur in the Skylab environment. The necessary diagnostic, therapeutic, and laboratory equipment needed to diagnose and to render first aid, resuscitative or supportive measures was stored in the Skylab Orbital Workshop. The resupply kit containing refrigerated laboratory and drug resupply items was stored in the Command Module.

Antihistamines reduce ulceration produced by indomethacin
Studies indicate that therapeutic application of antihistamines such as, metiamide, promethazine, or pyrilamide, may reduce occurance of gastric ulceration produced by indomethacin.
