The present invention is an automated image analysis framework for cervical cancerous lesion detection. The present invention uses domain-specific diagnostic features in a probabilistic manner using conditional random fields. In addition, the present invention discloses a novel window-based performance assessment scheme for two-dimensional image analysis, which addresses the intrinsic problem of image misalignment. As a domain-specific anatomical feature, image regions corresponding to different tissue types are extracted from cervical images taken before and after the application of acetic acid during a clinical exam. The unique optical properties of each tissue type and the diagnostic relationships between neighboring regions are incorporated in the conditional random field model. The output provides information about both the tissue severity and the location of cancerous tissue in an image.

[PROBLEMS] To provide lipase activity determination reagents which function by an enzymatic method. The reagents are easy to use in an ordinary clinical examination, have excellent handleability, and are excellent in accuracy and reproducibility. [MEANS FOR SOLVING PROBLEMS] Lipase activity is determined with any of reagents which comprise a low-concentration buffer and a diglyceride dissolved therein. The diglyceride is used as a substrate for lipase, whereby the liquid reagents can have long-term storage stability. One of the reagents converts a monoglyceride yielded by a lipase reaction into glycerol with the aid of monoglyceride lipase, and further contains glycerol kinase, pyruvate kinase, lactate dehydrogenase, reduced NAD, ATP, and phosphoenol pyruvate. Another reagent converts a monoglyceride yielded by a lipase reaction into glycerol with the aid of monoglyceride lipase, and further contains glycerol kinase, glucose, ADP-dependent hexokinase, glucose-6-phosphate dehydrogenase, oxidized NAD or oxidized NADP, and ATP. A further reagent converts a monoglyceride yielded by a lipase reaction into glycerol with the aid of monoglyceride lipase, and further contains glycerol kinase, glycerol-3-phosphate oxidase, peroxidase, and a dye which colors in the presence of hydrogen peroxide.
