    摘要: A chloramine generator is used in the manufacture of organic hydrazines wherein water is introduced into the generator to prevent plugging by the by-product ammonium chloride while preventing the chloramine from dissolving in the water. The chloramine is discharged directly into the hydrazine reactor without isolation of chloramine as an intermediate.

    摘要: This invention relates to biotechnology, more particularly, to water-soluble polymeric delivery systems for the imaging, evaluation and/or treatment of rheumatoid arthritis and other inflammatory diseases. Using modern MR imaging techniques, the specific accumulation of macromolecules in arthritic joints in adjuvant-induced arthritis in rats is demonstrated. The strong correlation between the uptake and retention of the MR contrast agent labeled polymer with histopathological features of inflammation and local tissue damage demonstrates the practical applications of the macromolecular delivery system of the invention.
