The invention provides systems and methods for providing a diagnostic examination to a patient, including, but not limited to a determination of the permeability of a patients' body cavity.

Systems and methods of detecting interstitial cystitis

Metastable liposomal formulations for hydrophobic drug delivery to a tissue or tissue lumen such the bladder have been developed. These are at least one micron in diameter and formed of one or more lipids having entrapped in the lipid a hydrophobic therapeutic, prophylactic or diagnostic agent. The greater stability of these liposomes, as well as the enhanced transfer of entrapped agent into the adjacent tissue, provides for better delivery, especially of hydrophobic agents such as tacrolimus which does not penetrate tissue well. The metastable liposomal formulations can be administered locally, preferably by instillation, or topically, for example, by spraying or painting, to a tissue or tissue lumen such as the bladder in need of treatment.

Delivery of agents using metastable liposomes

Provided are liposomes that encapsulate adenosine. The liposomes may be formed from sphingomyelin or a combination of sphingomyelin and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) or a combination of sphingomyelin and 1,2-dimyristoyl-sn-glycero-3-phosphorylglycerol (DMPG) or a combination of sphingomyelin, DMPG, and DMPC. The liposomes encapsulating adenosine may be used to induce cartilage regeneration, treat osteoarthritis, alleviate joint pain, and/or slow, arrest, and/or reverse progressive structural tissue damage associated with osteoarthritis or treat osteoarthritis, rheumatoid arthritis, acute gouty arthritis, and/or synovitis. The liposomes may release adenosine for up to two weeks.
