Streszczenie angielskie:
To establish the ultrastructural criteria of suicide muscle cell programme-apoptosis we investigated the muscle biopsies of acute fatal spinal muscular atrophy (SMA) infants with gene survival motor neurone (SMN) exon 7 deletion. The muscle cell apoptosis was characterised by precisely sequential morphology of both cell nucleus and sarcoplasm. The most characteristic feature was the aggregation of nuclear chromatin initially into peripherally located ring and later into uniformly dense, dark masses. Accompanying features included sarcoplasmic condensation cell shrinking and fragmentation into multiple bodies. The coexistence of muscle cells at different stages of apoptosis in the same tissue section was the most prominent and specific features of suicide muscle cell progarmme. The appearance of an identical sequence of ultrastructural changes in muscle as observed in other tissues suggesrs that a unique mechanism is involved in genetically programmed cell death.

Streszczenie angielskie:
Andersen syndrome (AS) is a rare, inherited disorder characterized by periodic paralysis, long QT (LQT) with ventricular arrhythmias, and skeletal developmental abnormalitise. We recently established that AS is caused by mutations in KCNJ2, which encodes the inward rectifier K+ channel Kir2.1. In this report, we characterized the functional consequences of three novel and seven previously described KCNJ2 mutations using a two-microelectrode voltage-clamp technique and correlated the findings with the clinical phenotype. All mutations resulted in loss of function and dominant-negative suppression of Kir2.1 channel function. In mutation carriers, the frequency of periodick paralysis was 64 p.c. and dysmorphic features 78 p.c. LQT was the primary cardiac manifestation, present in 71 p.c. of KCNJ2 mutation carriers, with ventricular arrhythmias present in 64 p.c. While arrhythmias were common, none of our subjects suffered sudden cardiac death. To gain insight into the mechanismof arrhythmia susceptibility, we simulated the effect of reducdd Kir2.1 using a ventricular myocyte model. A reduction in Kir2.1 prolonged the termkinal phase of the cardiac action potential, and n the setting of reduced extracellular K+, nduced Na+/Ca2+ exchanger-dependent delayed afterdepolarizations and spontaneous arrhythmias. These findings suggest that the substrate for arrhythmia susceptibility in AS is distinct from the other forms of inherited LQT syndrome.

Streszczenie angielskie:
Deficiency of dystrophin in skeletal muscles is supposed to be responsible for all the symptoms associated with Duchenne dystrophy (DMD) and Becker dystrophy (BMD). The dystrophin-deficient mdx mice, however, are clinically almost asymptomatic. Hence, other factor(s) might be responsible for the muscle pathology in DMD and BDM. As sulfhydryl groups are involved in mainatining the structure of membranes and the protein-phospholipid interactions, total, protein-bound and free sulfhydryl groups (-SH) in DMD, BMD, limb-girdle dystrophy (LGMD) and the mdx mice muscles have been determined. A significant decrease of total and protein-bound - SH groups content and an increased proportion of free - SH groups in DMD and BMD was found. In LGMD the changes of total and protein-bound - SH groups content were less expressed. In the mdx mice muscles te content of - SH groups was generally normal, only a higher than normal proportion of free - SH groups content in old and senile animals, especially in their diaphragm, was present. To test the sercolemmal integrity, albumin/creatine kinase (CK) influx/efflux was determined. In early stages of DMD and BMD the albumin influx was increased. In advanced stages of these diseases albumin influx was not observed. In LGMD albumin penetration was present only in a few fibres. CK efflux in vitro was incrased both in early and advanced DMD cases. IN BMD adn LGMD CK efflux was increased only in early stages of the diseases. In mdx mice an increased influx/efflux of albumin/CK was stated in adult animals. The changes persisted in the mdx mice an increased influx/efflux...
