Abstract: A pericardial-cavity observing method including: a step of inserting an endoscope sheath and an endoscope into a space between the heart and the pericardium; a step of disposing a protruding portion closer to the pericardium than an optical member is so that an angle that is formed between a centerline that passes through a center of the protruding portion and a center of the optical member and a tangent of the pericardium that passes through a foot of a perpendicular line drawn, from the center of the optical member of the endoscope, to the pericardium sagging down from the protruding portion toward the heart becomes greater than an angle formed between the centerline and an external common tangent of the protruding portion and the optical member; and a step of observing the heart by means of the endoscope.

Abstract: An apparatus including a detecting unit that detects information indicating a state of an organism from the organism or an organism specimen extracted from the organism and outputs the detected information as a current, a current-voltage conversion circuit that converts the current output from the detecting unit into a voltage, a double-integration-type A/D conversion circuit having an integration capacitor that is charged based on a voltage output from the current-voltage conversion circuit and is thereafter discharged, and a counter that measures a charge time during which the integration capacitor is charged and a discharge time during which the integration capacitor is discharged, the A/D conversion circuit converting into digital quantities the charge time and the discharge time measured by the counter, and outputting the digital quantities, and an information processing unit that calculates a state quantity of the organism based on the digital quantities output from the A/D conversion circuit.
