Abstract: PURPOSE: A method for editing a report using a user-defined function is provided to enable a user to edit a user-defined view by making the user define a data source, generating and displaying it as a tree type view on an inline view window. CONSTITUTION: A query sentence is written through user definition in order to write the report by editing only the data wanted to the user(S100). The written query sentence is grammatically verified(S110). The view as a tree type is generated in the inline window of an edit window by interpreting the query sentence(S130). A field of the report is edited on a report edit window of the edit window by using the tree type view(S140). An SQL(Structured Query Language) sentence corresponding to the field of the edited report is automatically generated(S150). The data matched with the SQL sentence is searched from the relational database(S160). The searched corresponding data is connected to the field according to a connection relation(S170).

Title: Prostaglandin endoperoxide H synthase biosynthesis inhibitors
IPC: A61P29/00
Filed: 1999-10-27
Abstract: The present invention describes pyridazinone compounds of formula (I) which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectively of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).

Title: Method for the treatment of cerebral ischaemia and use of erythropoietin or erythropoietin derivatives for the treatment of cerebral ischaemia
IPC: A61K38/22
Filed: 1999-12-13
Abstract: The present invention relates to a method for the treatment of cerebral ischaemia and a drug for the treatment of cerebral ischaemia in particular in humans, as occurs for example in the case of stroke patients. It was found surprisingly that peripheral administering of erythropoietin to the cerebral tissue affected by the ischaemia has a distinctly protective effect. Erythropoietin has the effect thereby that the region of the cerebral tissue which is damaged permanently, in particular in the penumbra, is dramatically reduced relative to conventional measures in the case of cerebral ischaemia without erythropoietin administration.
