[Peritoneal dialysis in a patient with right hemiparesis, lupus nephritis, significant insufficiency of arteries of aortic arch and celiac disease: case report].

Peritoneal dialysis (PD) is a method of choice in patients in whom there are difficulties concerning creation of AV fistula. A 38-year old female patient came to our hospital because of a need of making an AV fistula. She had end-stage renal insufficiency of unknown origin.

Influence of innervation on molecular forms of acetylcholinesterase in regenerating fast and slow skeletal muscles.

Nerve-intact muscle regenerates were prepared by ischemic-toxic injury of slow soleus (SOL) and fast extensor digitorum longus (EDL) muscles of the rat. Rapid innervation of regenerating myotubes modified intrinsic patterns of AChE molecular forms, revealed by velocity sedimentation in linear sucrose gradients. Regarding their onset, the effects of innervation can be classified as early and late.

Two types of focal accumulations of acetylcholinesterase appear in noninnervated regenerating skeletal muscles of the rat.

Muscle fibers in the soleus muscle of the rat, injured by bupivacaine and free autografting, were allowed to regenerate within their old basal laminae. Histochemical and cytochemical analysis of newly synthesized acetylcholinesterase (AChE) revealed that two kinds of focal accumulations of AChE appeared in regenerating myotubes. First, AChE gets concentrated at the sites of the former motor endplates.

Molecular forms and localization of acetylcholinesterase and nonspecific cholinesterase in regenerating skeletal muscles.

Molecular forms and histochemical localization of acetylcholinesterase and nonspecific cholinesterase were analysed in muscle regenerates obtained from rat EDL and soleus muscles after ischaemic-toxic degeneration and irreversible inhibition of preexistent enzymes. Regenerating myotubes and myofibres produce the 16S AChE form in the absence of innervation. The 10S AChE form prevails over 4S form with maturation into striated fibres.
