A silver halide emulsion improved in radiation resistance is disclosed, comprising tabular grains having an average aspect ratio of 20 to 500 and an average spacing between twin planes of 10 to 160 A, and at least 80% by number of the tabular grains being accounted for by hexagonal tabular grains having an adjacent edge ratio of not less than 1. A circulating pump injects maintenance water into the reactor, and the used maintenance water is pumped out to a disposal location or device by the same pump. The housing has a base plate, a surrounding wall upwardly extending from the base plate and a plurality of supporting members disposed at the top of the surrounding wall, wherein the surrounding wall defines an opening. The pivot axis is generally aligned with an insertion point at which the instrument is inserted into the patient. Also provided are compositions and methods of preventing inflammation of the heart of a subject, comprising administering to the subject an effective amount of an inhibitor of Calmodulin Kinase II, whereby the administration of the inhibitor prevents inflammation of the heart in the subject.
