概要 By x-ray diffraction study (at BL45XU in SPring 8), the equatorial reflection ratio of I(1,0) and I(1,1) was well related to the peak tension in rat papillary muscle, showing that a larger tension accompanies a smaller ratio. The correlation between the intensity ratio and the tension, is not mediated by the SL, but holds even when the tension varies depending on the specimen at the same SL. This is consistent with the interpretation that the intensity ratio in systole is related to the number of cross-bridges formed in contraction.
