“…Recording of multiple unit nerve activity. Conventional nerve recording techniques were used for multiple unit recordings from the pudendal nerve efferent fiber as described in a previous report (37). The firing frequency of each filament was recorded by placing the nerve fiber across a pair of thin bipolar stainless steel wire electrodes.…”

Reflex plasticity between pelvic afferent and pudendal efferent nerve fibers was examined in anesthetized rats. Brief high-frequency electric stimulation (300 pulses at 100 Hz) of the pelvic nerve afferent fiber produced a long-lasting potentiation of the pelvic-to-pudendal reflex (PPR). This tetanization-induced potentiation was abolished by a selective N-methyl-D-aspartate (NMDA) receptor antagonist and attenuated by a non-NMDA excitatory amino acid receptor antagonist. However, the GABA(A)-receptor antagonist had no effect on this potentiation. Both intrathecal glutamate (0.1 mM, 2-5 microl it) and NMDA (0.1 mM, 2-5 microl it) induced a potentiation of PPR similar to that of tetanization. Agonist-induced potentiation was shorter than tetanization-induced potentiation. The duration of the contraction wave of intraurethral pressure, elicited by PPR, was elongated by tetanization-induced potentiation, whereas the peak pressure was not affected. All these results demonstrate that brief high-frequency stimulation of the pelvic nerve afferent fiber can induce a distinct and long-lasting modulation in PPR activity and this change may be involved in nociceptive C afferent-induced obstructive urinary dysfunctions.

Taiwan has a unique cultural milieu and integrated medical education so that is a bellwether for acupuncture research. Pioneer researches here on electrophysiology and neuroendocrine illustrate a crucial role of the central nervous system (CNS) plays in acupuncture treatment. With different frequency of stimulation, acupuncture can elicit different physiologic responses in the CNS and neuroendocrine systems. Researches in Taiwan on the autonomic nervous system (ANS), cardiovascular system, meridian theory, and acupoint specificity further shed light on the mechanism of acupuncture treatment. The strong research background in Taiwan enables clinicians here to conduct integrated trials on different disorders. Pain syndromes and neurologic disorders are the leading issues on acupuncture clinical trials. Novel concepts and studies hailed from Taiwan have great impact worldwide. In addition to pain syndromes, Taiwanese clinicians pay much attention to diverse kinds of diseases. This broadens the spectrum of acupuncture trials and clinical application of acupuncture treatment. The exploration conducted in Taiwan leads acupuncture research worldwide.
