Comparative Analysis Of Hospital Utilization In Urban And Rural Counties, James R. Dingels Jan 1976

Comparative Analysis Of Hospital Utilization In Urban And Rural Counties, James R. Dingels

Journal of the Minnesota Academy of Science

Hospital utilization, when measured as patient days per population, exhibited generally insignificant relationships with factors concerning population characteristics, hospital resources, financial assistance, and degree of urbanization. Adjusted multivariate linear regression results indicated that number of physicians per population did possess significant effects, while other independent variables remained significant. Additional research, as well as refinement of present data, appear paramount to further validation procedures.


Chemicals And Food: An Account About Additives, Wayland E. Noland Jan 1976

Chemicals And Food: An Account About Additives, Wayland E. Noland

Journal of the Minnesota Academy of Science

Food additives are listed by functional category and discussed in terms of the scale of their use and relative risks in terms of long-term human toxicity. The greatest risks appear to lie with the antimicrobial preservative agents, and food colors (which serve only a cosmetic purpose); these and the synthetic sweeteners are discussed in relatively greater detail.


Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson Jan 1976

Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson

Journal of the Minnesota Academy of Science

Research results from studies of the physiological effects of aerosal propellants on animals and people are summarized. The papers selected for this summary were published between 1968 and 1975. Effects of the 15 chlorofluorocarbons used as propellants have been recorded on the cardiac, pulmonary and respiratory functions of a number of animal species as well as man. The fifteen propellants have been classified into four groups on the basis of their degree of toxicity. Fluorocarbon 11, the most frequently used propellant, is in group 1, the most toxic. The relative toxicity of each of the 14 other propellants compared with …


Measurement Of Permeability Of The Cell Membrane To Water, Richard Moore, Frederick Thornburgh, Donggyu Jin Jan 1976

Measurement Of Permeability Of The Cell Membrane To Water, Richard Moore, Frederick Thornburgh, Donggyu Jin

Journal of the Minnesota Academy of Science

The water permeability was measured for blood cells from normal subjects and for blood cells from patients with leukemia. The method of measurement of the kinetics of water influx employed a stopped flow apparatus. The method of calculation of results was based on irreversible thermodynamics. The measurements and calculations were both performed with the assistance of a computer. The water permeability of the leukemic cells was decreased from normal, and the values were more variable than normal. Leukemia changes the structure of the cell membrane.
