説明
Abstract 1. 1. Anterior byssus retractor muscle of Mytilus (ABRM) was stimulated to contract by ACh (acetylcholine) and effects of temperature (5–30°C), FDNB (1-fluoro 2,4 dinitro-benzene) and IAA (iodoacetic acid) on tension response were examined. 2. 2. Isometric tension was highest at the temperature range of 10–20°C and decreased at higher and lower temperature than that range. 3. 3. The rate of tension decay after washing of ACh was accelerated by the increase of temperature. 4. 4. Tension redevelopment after release of 1 % during contraction was much smaller at 5°C than at 20°C. 5. 5. Tension development by ACh and the rate of tension decay after washing of ACh were remarkably decreased by the treatment of FDNB or IAA. 6. 6. The above results were discussed from the viewpoint that energy metabolism might be related to catch.
