摘要:
This invention relates to a method of diagnosing cancerous diseases, which comprises measuring the amount of UDP-N-acetylglucosamine:glycoprotein N-acetylglucosaminyl-transferase in body fluid and evaluating the increase in its amount for the diagnosis of hepatic diseases.AFP, CEA and .gamma.-glutamyltranspeptidase have hitherto been used as tumor markers for the diagnosis of hepatic cancer. But these conventional tumor markers show a positivity rate of about 60%, making early diagnosis almost impossible.The method of this invention employs UDP-N-acetylglucosamine:glycoprotein N-acetylglucosaminyltransferase as tumor marker, whereby early diagnosis of hepatic cancer can be made almost completely.

[Problems] The objective is to provide a new low-toxic drug for external use for intractable diseases, such as erosion, decubitus, and skin ulcer, that prevents cicatrization and reduces iodine accumulation on wound surfaces with sufficiently promoting healing.[Means for solving problem] Preparation of a wound treatment drug for external use containing oily bases and iodine but substantially no white soft sugar, which is a characteristic of the drug of this invention. The invented drug prevents infection through the wound surface due to a sufficient bactericidal effect of iodine, and promotes wound healing, prevents cicatrization and reduces iodine accumulation on the wound surface by maintenance of appropriate moisture in the wound surface due to a moisturizing effect of oily bases.
