The present invention relates to a biocompatible nanoparticle and a use thereof and, more specifically, to a biocompatible nanoparticle formed by irradiation an electron beam to an aqueous solution comprising at least one substance selected from the group consisting of a polysaccharide, a derivative thereof and a polyethylene glycol, thereby inducing inter-molecular cross-linking or intra-molecular cross-linking, and to a use of the biocompatible nanoparticle in a drug carrier, a contrast agent, a diagnostic agent or an intestinal adhesion prevention agent or for disease prevention and treatment.

The present invention relates to the field of traditional Chinese medicine formulation, particularly to a composition and the preparation method and use thereof. The traditional Chinese medicine composition provided by the present invention is produced from raw materials comprising TARAXACI HERBA, GLYCYRRHIZAE RADIX ET RHIZOMA, PLATYCODONIS RADIX, CITRI RETICULATAE PERICARPIUNM and PHYLLANTHI FRUCTUS. The traditional Chinese medicine composition adopts fewer herb medicines. By reasonable combination, the various herbal medicines mutually reinforce in terms of the effects of clearing throat, anti-inflammation and reducing phlegm, exhibit obvious synergistic effect. Pharmacological tests and clinical trials indicate that the traditional Chinese medicine composition has significant throat clear, anti-inflammatory, expectorant effects (p<0.05), and has no obvious toxic and side effects.

Provided are mucolytic agents represented by formula (Ia)-(Id): ##STR00001##
where the structural variables R.sub.1, R.sub.2, R.sub.5 and R.sub.6 are as defined herein. Also provided are a variety of methods of treatment which take advantage of the mucolytic properties of the compounds represented by formula (Ia)-(Id).

Film products, especially suitable for oral delivery, which can be formed during manufacture in the form of large and/or heavy film strips or sheets and subsequently cut into uniform dosage units, each dosage unit being uniform in content and having distributed therein a linear polysaccharide, such as pullulan, a plasticizer, and an active component.

The present invention relates to pharmaceutical and nutraceutical compounds and methods for reducing inflammation, blood sugar, gastric acid, symptoms of allergy, common cold and flu, as well as treating infections and pain associated with trauma, medical procedure, and diseases and disorders in subjects in need thereof. The compounds and methods proposed by this invention are related to essentially a mixture of naturally accruing and/or synthetic substances in certain ratios, administration protocols, and delivery systems that amplify their medicinal qualities and reduce side effects, making their clinical application feasible.
