Voltage- and Agonist-Induced Activation of Smooth Muscle of the Human Upper Urinary Tract: Different Mechanisms
1985
Smooth muscles are such a remarkably diverse group of tissues that the difference in properties between any two of them may be as great as between a smooth muscle and a striated muscle. With this diversity it is not surprising that the ways in which different stimuli initiate contraction are also extremely varied and interesting although we still know very little about the details of the mechanisms involved. In an attempt to shed some light on the cellular contraction cycle of smooth muscle of the human upper urinary tract, this article will focus on two topics: 1. Previous findings in smooth muscle research will be summarized and discussed briefly as they are pertinent to an understanding …
Papaverine in Human Bladder Muscle
1989
It is generally assumed that drugs which induce relaxation of smooth muscles may be of clinical importance in some urological disorders; such drugs are indeed widely used, for example, in the therapy of unstable bladders or to facilitate the passage of ureteral stones. Recently, papaverine has been shown to be very effective, e.g., in relaxing smooth muscles of the corpus cavernosum penis, thereby inducing erections in many impotent men (Virag 1982). The purpose of this study is to determine the relaxing properties of papaverine in isolated muscle strips from the human detrusor and to evaluate its potential clinical importance.
Direkte Dickenmessung an Muskelstreifenpräparaten und Gewebsschnitten
1967
An apparatus for direct measurement of the thickness of tissue slices and muscle strips is described. Micrometer callipers are used, the proper adjustment of which is indicated by the sudden scale deflection of an ohmmeter. In comparison with the method of calculation based on a measurement of the area of the slice, this technique is time-saving and the results are more accurate and reproducible.
