Demonstration of the structural connections of the longitudinal muscle cells and circular muscle cells,and interconnections between the two,in the alimentary canal of an oligochaete,Branchiura sowerbyi B.

Summary The longitudinal and circular muscle cells of the alimentary canal of the oligochaete wormBranchiura sowerbyi show intercell couplings. These couplings occur between adjoining cells of the same or of the other orientation.We wish to thank Dr S. Kawaguti, Prof. emeritus of Okayama University, for his kind advice.     

Comparative analysis of phospholamban phosphorylation in crude membranes of vertebrate hearts

Summary Phospholamban, a sarcoplasmic reticulum phosphoprotein, is present in the hearts of mammalian, avian, amphibian, and fish species. Phylogenetic changes are indicated by marked differences among species in cardiac phospholamban content and by the absence of Ca²⁺/calmodulin-dependent phospholamban phosphorylation at an early developmental stage.

Calcium uptake by sarcoplasmic reticulum from nerve-intact and standard skeletal muscle grafts

Summary A freely grafted rat soleus muscle exhibits a decrease in velocity and capacity of SR calcium uptake. This deficit is not prevented by maintaining neural connections (nerve-intact graft) during grafting. Thus the greater mechanical capability of nerve-intact grafts, relative to standard grafts, is not accompanied by any enhancement of the SR tubules.     

Diltiazem prevents the damage to cultured aortic smooth muscle cells induced by hyperlipidemic serum

Summary Diltiazem, a calcium antagonist, significantly reduced the increased⁴⁵Ca uptake and the number of dead cells in cultured aortic smooth muscle cells induced by hyperlipidemic serum.     

Colchicine-induced appearance (proliferation) of smooth sarcoplasmic reticulum in arterial smooth muscle cells

Summary Colchicine treatment resulted in the appearance and proliferation of smooth sarcoplasmic reticulum in some smooth muscle cells of the aortic and pulmonary trunk walls in the rabbit. The significance of cytoplasmic microtubules and/or membrane-bound tubulin for the morphogenesis, functioning and control of smooth endoplasmic reticulum in different kinds of cells is discussed.     

The role of muscle in determining growth and size in teleost fish

Summary Rapid growth to large size in fish results from a sustained recruitment of new fibres into their axial series of myomeres. Cessation of recruitment at a small fish size leads to slow growth and a small final size of the fish. Fibre growth dynamics of fishes evidently govern growth and size through fibres' surface area to length ratios, which control their nutrient assimilation rates.
