Abstract: A respiratory monitor is disclosed that includes features for conducting multiple pulmonary function tests in a single device and for detecting the presence of nitric oxide in exhaled breath. Also described is a mouthpiece that allows for separate inhalation and exhalation pathways and for filtering inhaled and exhaled breath for predetermined species prior to exhalation into the respiratory monitor. The monitor further allows for wired, wireless and network connectivity and for cloud-based systems for communicating and correlating pulmonary data as well as relevant environmental data and displaying the data for use by patients and health care professionals.

Abstract: In accordance with the invention there is provided a method of treating a human subject to prevent leakage of serum proteins from capillary endothelial junctions during a period of increased capillary permeability. The invention also provides a method for preventing the harmful effects of free radicals on cellular membranes and other organelles. The method comprises administering to a subject an effective amount of a composition comprising at least one polysaccharide selected from the group consisting of hydroxyethyl starch and dextran of varying molecular sizes and at least one member of the group consisting of superoxide dismutase, glutathione peroxidase, catalase, hydroxyethyl rutoside, cyclic adenosine monophosphate and vitamin C. The compositions contain the macromolecules in a molecular size and concentration to effectively stabilize the capillary membrane.

Abstract: There is provided a method of treating a human subject to prevent leakage of serum proteins from capillary endothelial junctions during a period of increased capillary permeability. The method comprises administering to a subject an effective amount of a composition containing hydroxyethyl starch, dextran or hydroxyethyl starch and dextran. The compositions contain these macromolecules in a molecular size and concentration to effectively seal the capillary junctions and stabilize the capillary membranes. The sealant effect is accomplished by a biophysical process due to the adhesiveness and configuration of the macromolecules, and because of their size. There is also provided a means of treating viral and other bacterial infections and cancer, by introducing into the composition of polysaccharide(s) a biological agent, preferably interleukin-2.
