Abstract: A high humidity method and an apparatus are described which are useful for conditioning a pulmonary and/or a cardiovascular system in a large animal. The method broadly comprises delivering a humidified air stream at a dew point temperature greater than the environmental ambient dew point temperature to an animal's respiratory tract.

Abstract: An endoscope comprises an operating body and an inserting portion extending therefrom. A distal end section of the inserting portion is formed into a resiliently bendable section. An angularly movable member is mounted within the operating body for angular movement around a center of rotation. The bendable section is operatively connected to the angularly movable member through a pair of operating wire sections. An operating member located exteriorly of the operating body is operatively connected to the angularly movable member. A biasing mechanism is associated with the operating body and includes a spring spirally wound within a casing. One end of the spring drawn out of the casing applies a spring force to a point of action on the angularly movable member spaced from the center of rotation thereof.
