Abstract: The invention relates to an electronic image pickup system whose depth dimension is extremely reduced, taking advantage of an optical system type that can overcome conditions imposed on the movement of a zooming movable lens group while high specifications and performance are kept. The electronic image pickup system comprises an optical path-banding zoom optical system comprising, in order from its object side, a 1-1st lens group G1-1 comprising a negative lens group and a reflecting optical element P for bending an optical path, a 1-2nd lens group G1-2 comprising one positive lens and a second lens group G2 having positive refracting power. For zooming from the wide-angle end to the telephoto end, the second lens group G2 moves only toward the object side. The electronic image pickup system also comprises an electronic image pickup device I located on the image side of the zoom optical system.

Abstract: An insertion assist device for an endoscope includes a grip, an operation portion, a liquid storage, and a tubular member. The grip includes a channel through an inside of which an insertion portion of the endoscope is inserted. The operation portion is configured to advance the insertion section by moving forward relative to the grip. The liquid storage is provided on an interior portion of the grip and configured to store a liquid. The tubular member is provided on an interior portion or an exterior portion of the insertion portion of the endoscope, is connected to the liquid storage at one end of the tubular member, and is configured to guide the liquid toward another end of the tubular member opposite to said one end.

Abstract: The purpose of the present invention is to provide a method for evaluating the possibility of suffering from pancreatic disease on the basis of the concentration of a pancreatic disease marker in a duodenal juice sample. The method for evaluating the possibility of suffering from pancreatic disease of the present invention has a step for (a) measuring the concentration of the pancreatic disease marker in a duodenal juice sample taken from a subject and a step for (b) evaluating the possibility of the subject suffering from pancreatic disease on the basis of the concentration of the pancreatic disease marker measured in step (a) and the age of the subject.
