Disclosed is an edema measuring method comprising the steps of: putting at least two pairs of electrodes on different locations selected in the body; making an alternating current to flow in the body via one pair of electrodes; measuring voltage appearing between the other pair of electrodes; calculating impedance on the basis of the supplied alternating current and the measured voltage; and calculating an index value representing the degree of edema on the basis of the impedance. Also, an apparatus using the method is disclosed.

A method and apparatus (100) of treating tissue adjacent a bodily conduit using thermotherapy, while preventing obstructions of the bodily conduit due to edema, includes injection of a drug-encapsulated within a heat-sensitive carrier, such as a liposome, within a region of tissue to be treated. The heat produced by the energy-emitting source (110) heats a portion of the tissue surrounding the bodily conduit to a temperature of approximately 43° C. for a time sufficient to destroy the heated portion of the tissue. In addition, the heat produced by the energy-emitting source (110) activates the heat-sensitive carrier to activate the release of the encapsulated drug and the drug targets the tissue to be heated. The focused energy of the energy-emitting source together with the compression acting on the target area can assist in delivering drugs to the target area so that a natural stent has a long term efficacy.

The present invention provides a method of treating edematous retinal disorders. The method comprises administration of a pharmaceutical formulation comprising a hydrolysis-resistant P2Y receptor agonist to stimulate the removal of pathological extraneous fluid from the subretinal and retinal spaces and thereby reduce the accumulation of said fluid associated with retinal detachment and retinal edema. The P2Y receptor agonist can be administered with therapeutic and adjuvant agents commonly used to treat edematous retinal disorders. The pharmaceutical formulation useful in this invention comprises a P2Y receptor agonist with enhanced resistance to extracellular hydrolysis, such as dinucleoside polyphosphate compounds, or hydrolysis-resistant mononucleoside triphosphate salts. The present invention also provides P1-(2′-deoxycytidine 5′-)P4-(uridine 5′-)tetraphosphate, tetra-(alkali metal) salts such as tetrasodium, tetralithium, tetrapotassium, and mixed (tetra-alkali metal) salts. The present further provides a pharmaceutical formulation comprising a P1-(2′-deoxycytidine 5′-)P4-(uridine 5′-)tetraphosphate, tetra-(alkali metal) salt, in a pharmaceutically acceptable carrier.

The present invention relates to the use of an immunogenic composition that comprises a porcine circovirus type 2 (PCV2) antigen for treatment of several clinical manifestations (diseases). Preferably, the clinical manifestations are associated with a PCV2 infection. Preferably, they include lymphadenopathy, lymphoid depletion and / or multinucleated / giant histiocytes. Moreover, the clinical symptoms include lymphadenopathy in combination with one or a multiple of the following symptoms in pigs: (1) interstitial pneumonia with interlobular edema, (2) cutaneous pallor or icterus, (3) mottled atrophic livers, (4) gastric ulcers, (5) nephritis and (6) reproductive disorders, e.g. abortion, stillbirths, mummies, etc. Furthermore the clinical symptoms include Pia like lesions, normally known to be associated with Lawsonia intracellularis infections.

Devices that employ external compression stocking-type garments in the treatment of edema, chronic wounds, deep venous thrombosis prevention or claudication all share a number of significant limitations. These include the frequent need for custom fitting to assure an appropriate fit, vigilant maintenance to assure a continued “good fit,” limited compliance with proper use by patients and difficulty of application. There is a large body of evidence demonstrating that patients often decline to wear the compressive stockings as prescribed or in the form that would be most beneficial because they find these devices to be difficult to put on and take off.Building on the limitations of existing therapies, and distilled lessons learned from the field of prosthetics and wound healing, the present invention employs vacuum-assisted negative pressure to provide compression and help pump fluid from the tissues of affected limbs. The device is embodied in the form of a flexible stocking-like garment that will utilize a pumping mechanism to generate negative pressure around the limb and thus create vacuum compression that will mobilize fluid in a limb and increase venous return to the heart. Through the use of a circumferential wrap, the present invention provides a major advance in both the distribution of vacuum and the securing of the device over the limb.

An apparatus for applying pressure to a body part comprising: a first sleeve comprising a multiplicity of pressure-applying resilient protrusions configured to apply a therapeutic pressure to a surface of the body part of a patient; and a second sleeve slidably received over the first sleeve, the second sleeve configured to apply a pressure to the first sleeve, thereby increasing the therapeutic pressure applied by the first sleeve on the limb.
