Equipment For Local Hyperthermia Therapy Of Cancer, Charles F. Babbs, James R. Oleson, John A. Pearce

Weldon School of Biomedical Engineering Faculty Publications

Rapid improvements in hyperthermia apparatus are being achieved by industrial and university-based research groups that have already led to the marketing of a variety of commercial systems for heat therapy of malignancy. These tissue heating systems employ microwaves, capacitively or inductively coupled radiofrequency current, or high intensity ultrasound to produce controlled local heating of tumor tissues. No single system is superior to others in all applications; each has its limitations.

Characterization Of The Oscillometric Method For Measuring Indirect Blood Pressure, L A. Geddes, M Voelz, C Combs, D Reiner, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

In this study, human subjects and dogs were used to determine the ability of the oscillometric method to indicate systolic and diastolic pressure. In the human studies, the auscultatory method was used as the reference. In the animal studies, directly recorded blood pressure was used as the reference. The ability of the sudden increase in cuff pressure oscillations during cuff deflation to indicate systolic pressure was examined and found to overestimate systolic pressure slightly in man, but more in animals. Systolic pressure was encountered when the cuff pressure oscillations were about one half of their maximum amplitude. However, in both …

Biology Of Local Heat Therapy For Cancer, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Successful cancer therapy must selectively destroy tumor tissue while sparing the host's normal tissues. Local heat treatment can have such a selective effect because abnormalities in tumor blood vessels supply less oxygen to heat-stressed tumor cells and are less efficient in cooling tumor tissue by blood perfusion.

Hydralazine-Enhanced Selective Heating Of Transmissible Venereal Tumor Implants In Dogs, William D. Voorhees Iii, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

This study was designed to test the hypothesis that vasodilator drugs can enhance selective heating of solid tumors by producing a favorable redistribution of blood flow between tumor and normal tissues. Subcutaneous transmissible venereal tumor implants were heated by inductive diathermy using Helmholtz coils in 8 dogs. The temperature rise in tumor and adjacent muscle was measured before and after giving hydralazine (0.5 mg/kg i.v.). Blood flow to the tumors and underlying muscle was measured with radioactive tracer microspheres. Before hydralazine treatment mean muscle blood flow was about one-third tumor blood flow (0.11  0.02 vs. 0.28  0.09 ml/min/g), …

Theoretical Feasibility Of Vasodilator-Enhanced Local Tumor Heating, Charles F. Babbs, David P. Dewitt, William D. Voorhees, Janet S. Mccaw, Rosanna C. Chan

Weldon School of Biomedical Engineering Faculty Publications

Normal arterioles, in contrast to the abnormal microvasculature of many solid tumors, provide a target for selective drug action that can enhance local heat treatment of the tumors. Measurements of tissue blood flow with radioactive microspheres and estimates of changes in blood flow with thermal clearance methods revealed that vasodilator drugs either decreased or did not alter blood flow in hamster melanoma, rat hepatoma, and canine transmissible venereal tumor, while increasing perfusion in adjacent normal tissues 2 to 4-fold. Solutions of the bio-heat transfer equation, which take into account such selective effects of vasodilators on blood flow in normal tissues, …

Cardiopulmonary Resuscitation With Interposed Abdominal Compression In Dogs, Sandra H. Ralston, Charles F. Babbs, Mark J. Niebauer

Weldon School of Biomedical Engineering Faculty Publications

This study was conducted to evaluate the hemodynamic effectiveness of a new modification of cardiopulmonary resuscitation (CPR), termed interposed abdominal compression- CPR (IAC-CPR). IAC-CPR utilizes all the steps of standard CPR with the addition of abdominal compressions interposed during the release phase of chest compression. Ventricular fibrillation was induced electrically in 10 anesthetized dogs, and either IAC-CPR or standard CPR was initiated while arterial and venous blood pressures and cardiac output were monitored. The two CPR methods were alternated every three minutes over a period of thirty minutes. The addition of interposed abdominal compressions to standard CPR improved arterial pressures …

Highway Finance — 1981 Update, Jean E. Hittle

Indiana Local Technical Assistance Program (LTAP) Publications

This Bulletin --- "HIGHWAY FINANCE - Update 1981" --- has been compiled to provide Local Road and Street Officials with a year-end report on the results of the 1981 gas tax legislation, as well as an updated estimate of anticipated revenue for Calendar Year 1982.

Total highway-user revenue for 1981 was up some $39 million over 1980 totals; this is about 6% over the totals forecast back in July. And on the basis of the 1981 experience, the 1982 total revenue estimate is up to $393 million -- a $23 million increase over the July forecast. If the 1982 experience …

County Storm Drainage Manual 1981, Christopher B. Burke

Indiana Local Technical Assistance Program (LTAP) Publications

This manual is a comprehensive catalog of procedures, design methods and criteria, and general background information which will enable the designer to quickly learn or review the basic principles of storm drainage design. Subjects included are the precipitation and hydrological cycle, runoff and its estimation, open channels, flow in gutters and inlets, stormwater storage, and storm sewer system design. Included in the appendices are basics of statistical analysis, fundamentals of hydraulics, and a list of regulatory agencies and governmental bodies which may have jurisdiction over drainage projects.
