    摘要: The present invention relates to contrast agents comprising water-soluble microbubble-generating carbohydrate microparticles in admixture with at least 10% w/w relative to the overall composition of a non-surface active material which is less water soluble than the carbohydrate. The contrast agents exhibit useful levels of contrast efficiency and/or stability and may be used in diagnostic applications such as ultrasound and MR imaging.

    摘要: The invention relates to non-crosslinked non-polypeptide polymers containing biodegradable lipophilic side chains incorporating methylene diester units of the formula --[--CO--O--C(R.sup.1 R.sup.2)--O--CO--]--, where R.sup.1 and R.sup.2 each represents a hydrogen atom or a carbon-attached monovalent organic group or R.sup.1 and R.sup.2 together form a carbon-attached divalent organic group. The lipophilic moieties are biodegradatively cleavable to yield a water-soluble polymer.

    摘要: The present invention provides an acid addition salt of 5-aminolevulinic acid (5-ALA) or of a 5-ALA derivative (e.g. a 5-ALA ester) with an acid which has a pKa of about 5 or less, preferably about 3 or less, with the proviso that the acid is other than hydrochloric acid. Particularly preferred salts are those derived from acids selected from the group comprising sulphonic acid and its derivatives, hydrobromic acid, sulfuric acid, nitric acid and phosphoric acid. The salts in accordance with the invention are particularly suitable for use as photosensitizing agents in diagnosis and photochemotherapy of disorders or abnormalities of external or internal surfaces of the body.

    摘要: The invention relates to methods of introducing drugs into cells which are located in body cavities. In particular, it provides a photosensitizing agent for use in a method of introducing a drug molecule into the cytosol of a cell located within a body cavity, said method comprising the step of contacting said cell with said photosensitizing agent and said drug molecule, and irradiating the cell with light of a wavelength effective to activate the photosensitizing agent. Such methods are particularly suitable for use in the delivery of cytotoxic drugs in the treatment of cancer, especially bladder cancer, ovarian cancer, cervical cancer, lung cancer, brain cancer, colorectal cancer and cancers of the oral and nasal cavity.
