[Endovascular revascularisation in patients with necrotic wounds and extended infrainguinal arterial disease]. / Endovaskulyarnaya revaskulyarizatsiya u patsientov s gnoino-nekroticheskimi ranami nizhnikh konechnostei s infraingvinal'nym protyazhennym porazheniem arterial'nogo rusla.

OBJECTIVE: To report own experience of endovascular interventions in patients with extended occlusive lesion (TASC II D) of the femoral-popliteal and tibial arteries and concomitant purulent-necrotic wounds. MATERIAL AND METHODS: We have analyzed literature data and own experience of endovascular interventions in patients with extended occlusive lesion (TASC II D) of the femoral-popliteal and tibial arteries and concomitant purulent-necrotic wounds. RESULTS: Endovascular strategy is preferable in a certain subgroup of patients with extended infrainguinal lesions. CONCLUSION: Considering own data, we assumed the need for routine correction of outflow pathways (simultaneous angioplasty of at least 2 tibial arteries). Primary results are encouraging, but further research is required.

[Influence of the efferent vestibular system on the vestibulo-spinal reflexes in the guinea pig]. / Vliianie éfferentnoi vestibuliarnoi sistemy na vestibulospinal'nye refleksy u morskoi svinki.

Influence of the efferent vestibular system on the vestibulo-spinal activity was investigated in the decerebrated, decerebellated guinea pigs. The efferent vestibular system was excited by electrical stimulation of the domain of efferent neurons in the medulla. Electromyographic activity of left and right triceps brachii was used as a test reaction. Muscle activity was initiated by means of the crossed extensor reflex and locomotion evoked by mesencephalic locomotor region stimulation. Adequate vestibular stimulation was performed by static shifts and cyclic tilting of an animal about a longitudinal axis. It has been demonstrated that the efferent system bilaterally inhibits the vestibulo-spinal activity. The stimulation of vestibular efferents decreases the intensity of vestibular influences, but does not change dynamics of vestibulo-spinal reflexes. Mechanisms of the vestibular efferent action on the vestibular control of the spinal motor activity are discussed.
