4 Possible Causes for Histochemically Normal Type 2 Muscle Fibers, Interfibrillar and Subsarcolemmal Vacuoles

  • Myopathy with Abnormal Lipid Metabolism

    CRC Press, ٢٨‏/١١‏/٢٠٠٨ - 432 من الصفحات Already established as a 'classic' in the field, Clinical Tests of Respiratory Function presents an authoritative yet accessible account of this complex area, fusing the basic principles of respiratory physiology with applications in clinical practice across a wide range of[…][books.google.com]

  • Steroid Myopathy

    Histochemical type-2 fiber atrophy muscles were low compared to normal muscles in three glycogenolysis enzyme activities plus four glycolysis enzyme activities.[ncbi.nlm.nih.gov] All 3 groups had statistically low mean values compared to normal muscles for glycogen phosphorylase activity.[ncbi.nlm.nih.gov] This suggests that the biosynthesis and phosphorolysis of glycogen are not involved in muscle fiber atrophy, and glucocorticoid administration does not activate muscle glycogen[ncbi.nlm.nih.gov]

  • Congenital Myasthenic Syndrome 14

    Type 1 fibers had a smaller mean diameter than type 2 fibers. The random distribution of the histochemical fiber types was maintained. EP Studies.[pnas.org] The number of AChR per EP, determined with 125 I-labeled α-bungarotoxin, was normal.[pnas.org] The muscle fiber membrane potential was similar to that recorded from control muscle fibers ( Table 2 ).[pnas.org]

  • X-Linked Reducing-Body Myopathy 1A

    The muscle fibers were generally smaller than normal. Figure 2. Figure 2. Histochemical and Ultrastructural Images of Myocardial-Biopsy Specimens.[nejm.org] The patient had a marked predominance of slow-twitch, oxidative (type 1) muscle fibers ( Figure 1D ) and mitochondrial proliferation ( Figure 1F ).[nejm.org]
