OBJECTIVE: Recently, we have demonstrated that embryonic ventral spinal cord motor neurons(ESMNs), transplanted into the distal stump of the axotomized tibial nerve, can grow into the denervated gastrocnemius muscle and form neuromuscular junctions. Our interest in study was to see whether these newly formed neuronal connections are physiologically active, and to electrophysiologically characterize the reinnervated motor units. MATERIAL AND METHODS: Three to eight weeks after transplantation rats were prepared for electrophysiological recording. Motor unit (MU) action potential and gross EMG were monitored. In eleven out of sixteen transplanted animals single unit and gross EMG were recorded after electrical stimulation of the transplant site. Total of 63 motor units were analyzed for their stimulus threshold (ST), latency and stimulus intensity, which is required to produce maximum firing. RESULTS: ST intensities activating MUs were significantly higher in transplanted animals than in controls. Maximum firing of MUs occurred at less than 1.2×T in the control but greater variation was observed in the transplanted animals ranging from 1.1×T to 1.6×T. No significant differences were found in the latencies of MU's firing following stimulation. MU firing was reversibly blocked by infusion of succinylcholine. CONCLUSION: we characterized the temporal, morphological and electrophysiological parameters of denervated skeletal muscle reinnervated by dissociated grafts of embryonic ventral spinal cord cells. MUs reinnervated by the embryonic motoneuronal transplant were physiologically active, with some properties similar to the MUs of the normal.

This study was performed to identify the effect of the hydrosalpinx fluid on sperm motility. It has been reported that the patients with hydrosalpinx show the outstandingly lower success rate than other patients having infertility by different factors. It is unclear that the cause of it is influenced by hydrosalpinx fluid directly or by secondary chronic inflammation of endometrium. We wanted to know if the hydrosalpinx fluid influences sperm motility parameters directly such that it is related to the development of infertility. Therefore, using computer assisted semen analyzer (CASA), we observed, from February to July, 1997, how sperm motility, sperm progressive motility, sperm curvilinear velocity, sperm lateral head displacement, sperm straightness and sperm linearity change after treating normal sperm with hydrosalpinx fluid to evaluate sperm function on infertility. The result was that the study group (n=32) has the tendency to differ from the control group (n=32) on sperm motility, progressive motility, curvilinear velocity, lateral head displacement, straightness and linearity. We concluded that the hydrosalpinx fluid, with varying degree, directly has the harmful effects on sperm motility parameters, that is, curvilinear velocity, lateral head displacement and linearity of sperm which are related to the hyperactivation, hence decreased capacitation.
