Provided is an enteric preparation for preventing and curing hyperuricemia and gout. The employing essential component of the preparation is enteric capsules of uricase. The causes of the hyperuricemia and the gout are that uric acid is over generated and / or the uric acid is diminished in discharging, and metabolic diseases increasing the density of serum uric acid. About one third of the uric acid of the human body is defecated from intestinal canals, and the uric acid entering the canals still can be reabsorbed. When the hyperuricemia and the gout happen, the proportion of the uric acid defecated from the intestinal canals is increased. The uricase is capable of rapidly effectively dissociating the uric acid. The uricase of the enteric preparation after being orally taken is disintegrated in the intestinal canals and is diffused from blood into the uric acid of the intestinal canals, preventing the uric acid from reabsorbing, thereby reducing the density of the serum uric acid, achieving the purposes of preventing and curing the hyperuricemia and the gout. The oral uricase has the characteristics of non-absorbent property by the intestinal canals, keeping out of blood circulation, no producing of antibodies of organisms and allergic response, providing a new method for preventing and curing the hyperuricemia and the gout.

An anti-rewet press fabric for paper and board machines includes a barrier layer such that during compression in the press nip, the water is forced through the barrier layer, but is prevented from flowing back to the paper web during expansion. The barrier layer comprises a continuous material possessing, for example square, rectangular, tetrahedral, circular or oblong conical inclusions with a smaller opening on the bottom than on the top of the structure. Each of these “funnels” effectively constitutes a one-way valve and creates a vacuum to prevent re-absorption of water by the paper sheet. Under pressure, the structure of the barrier layer allows water to flow into the cones and out of the smaller opening in the bottom. Upon expansion, the smaller opening in the bottom of the structure restricts backward water flow and creates a vacuum on the other side. The vacuum increases water retention in the press fabric and prevents rewetting of the paper sheet. Another embodiment of the invention is described herein, wherein the barrier layer exists as a separate fabric fed through a press section. In this embodiment, the “separate fabric” can just be the “conical inclusion sheet” itself. That is, the sheet itself constitutes an inventive belt having anti-rewet properties.
