Abstract：
:In 6 normotensive Wistar-Kyoto (WKY) and 6 spontaneously hypertensive rats (SHRs) anesthetized with urethane and chloralose, paralyzed, artificially ventilated, vagotomized with carotid sinus nerves bilaterally cut, somatosympathetic reflex discharges were recorded in cervical and renal nerves by stimulating group II and III cutaneous afferents in the sural nerve. Only a long-circuited, late supraspinal component reflex discharge could be elicited. After averaging the responses evoked by random stimulation, the latency of the reflex discharge was significantly longer in the renal than in the cervical sympathetic nerve, equally in the WKY rat and in SHR. In WKY rats the peak of sympathetic discharge corresponded to early expiration, whereas in SHRs--to late inspiratory phase. The duration of the reflex discharge elicited in inspiration was greater in SHR than in WKY rats. In WKY rats stimuli applied during phrenic discharge produced a reflex response of longer latency and of reduced amplitude than those applied in expiration. In SHRs the latency of the reflex response in the sympathetic cervical nerve was shorter during inspiration than in expiratory phase. The timing of the sympathetic reflex responsiveness within respiratory cycle in SHR and in WKY rats corresponded to strain-dependent opposite respiratory synchronization pattern of the spontaneous sympathetic activity characterizing each strain. No respiratory modulation of the somatosympathetic reflex was observed in the renal nerve of SHR. It is concluded that both spontaneous and evoked sympathetic activity is synchronized differently in SHR and in WKY rats and this difference is both species- and strain-dependent.
