The influence of the peptide hormone relaxin on the glycosaminoglycan (GAG) metabolism was investigated in the pubic ligament of the symphysis pubis and in serum of the virgin mouse. Fresh weight DNA and GAG content per 1 ligament is significantly increased, the level of water soluble protein is not affected. A shift in the electrophoretic GAG pattern by an increasing amount of hyaluronic acid and a decreasing amount of chondroitin sulfate and dermatan sulfate can be observed. Concerning GAG-splitting enzymes (N-acetylglucosaminidase, arylsulfatase, beta-glucuronidase) the N-acetylglucosaminidase reveals a significant increase of its activity in the interpubic ligament and in the serum. The data demonstrate that relaxin treatment induces some changes in the GAG metabolism.
Information about health is a requisite for our health care system.It is presented in a variety of forms and formulations and offered mostly to promote special health products or health-related services.In view of the possibilities of new media such as computers and the internet and with respect to the overwhelming flood of health information, the question arises how to handle such information from a regulatory point of view in order to guarantee truthfulness and quality. In the following paper, four different categories of health information are identified and analyzed with respect to specific problems.Consideration is also given to whether there are measures of quality assurance available, which should be employed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
