摘要:
A method for the treatment of erectile dysfunction comprises instilling intra meatally an aqueous solution containing prostaglandin-containing liposomes and a detergent for lysing the liposomes. A pharmaceutical composition for treating erectile dysfunction comprises a two-component system. The first component comprises a predetermined amount of lyophilized prostaglandin-containing liposomes. The second component comprises a predetermined volume of an aqueous solution containing a detergent, preferably PEG(9) octylphenyl ether, for lysing the liposomes. Dissolution of the lyophilized prostaglandin-containing liposomes yields a liquid composition suitable for application to the penis, preferably intra meatally, to effect erection.

A device and methods for the real-time monitoring of stem cells in a stem cell transplant. The device comprises a linear member and particle detection device configured to occupy the lumen of a catheter while the catheter is in place to administer a stem cell transplant to a delivery site in the body of a patient. Monitoring of the stem cells permits the device to provide signals to a computer processor for the determination of one or more characteristics of stem cells in the stem cell transplant.

A method is provided for inducing a systemic immune response to an antigen selected from hepatitis B and hepatitis C antigens in a mammal. The method comprises orally administering lyophilized multilamellar liposomes containing the antigen. The liposomes have a size of from 20 nm to 20 microns. The antigen-containing liposomes are absorbed in the Peyer's patches of the gut. Sufficient antigen-containing liposomes are taken up by macrophages in the Peyer's patches to induce a systemic immune response to the antigen.

A safe and inexpensive method of measuring blood flow in experimental animals using non-radioactively labeled microspheres is provided. The microspheres may be comprised of a variety of materials, including latex and agarose, and may be labeled with colored dyes or by linkage to enzymes, plant enzymes being preferred because they do not occur naturally in an animal's system. After injection and circulation of the microspheres throughout the animal's system, blood flow to particular tissue may be measured by counting the number of microspheres in the tissue sample, the initial number of microspheres in the animal's blood stream having been measured shortly after injection. In the case of microspheres labeled with colored dyes, the spheres may be counted in tissue either after separation from the tissue or while still trapped in the tissue's capillaries. Techniques for separating the microspheres from blood and tissue are also provided.

A medicament for treating cystitis and a method of treatment are provided. An agent to repair the damaged glycosaminoglycan (“GAG”) layers lining the urothelium, noted in cystitis, such as pentosan polysulfate, hyaluronic acid, chondroitin, etc., is provided in a liposomal carrier. Cystitis is treated by intravesically administering to a patient a therapeutically effective dose of the medicament.

A method is provided for inducing a systemic immune response to an antigen selected from inactivated HIV I and HIV II antigens in a mammal. The method comprises orally administering lyophilized multilaminar liposomes containing the antigen. The liposomes have a size of from 20 nm to 20 microns. The antigen-containing liposomes are absorbed in the Peyer's patches of the gut. Sufficient antigen-containing liposomes are taken up by macrophages in the Peyer's patches to induce a systemic immune response to the antigen.

摘要:
A stent or vascular graft for supporting a blood vessel or organ lumen is coated with a biodegradable, resorbable and hemocompatible surface substrate. Biologically active microspheres which controllably release the biologically active agent into the vessel wall or organ to inhibit restenosis of the stent is embedded in the stent substrate. The biologically active microspheres include encapsulated PGE1 in a water soluble polyethylene glycol mix, which over a period of time dissolves and releases the PGE1 into the vessel wall or organ.
摘要:
A process for making a volumetric determination of the quantity of a fluid, such as a liquid, by evaluation of a small sample of that fluid. The method comprises labeling microspheres with a non-radioactive substance and introducing the labeled microspheres into a body of fluid for which a determination is to be made. The microspheres are allowed to disperse in the body of fluid. Thereafter, a sample of the fluid which is of know or measurable volume, is selected. The number of microspheres present in the sample is then determined, from which a calculation of the volumetric measurement of the fluid may be made. The process is also adaptable to measuring the flow rate of a moving stream of fluid, since volume is one of the parameters of flow rate, and is also adaptable to determine the percentages of fluid components present in a mixture thereof.

A method for treating female sexual dysfunction or for female sexual enhancement comprises administering to the vagina a composition comprising a prostanoid compound having a vasodilating effect in a pharmaceutically acceptable vehicle. The amount of prostanoid compound administered ranges from about 0.05 mg to about 3 mg, and preferably from about 0.125 mg to about 1 mg. Preferably the prostanoid compound is prostaglandin E-1 and the pharmaceutically acceptable vehicle is methylcellulose.
