The actions of shakuyaku-kanzoh-toh (SK), a prescription of the traditional Chinese medicine, on an isolated guinea pig ileum were studied by comparing those of shakuyaku (S) (peony root, Paeoniae Radix) and kanzoh (K) (licorice root, Glycyrrhizae Radix). SK, S and K suppressed the neurogenic contractions of ileum induced by electrical stimulation and(More)
A 51-year-old man had suffered from attacks of quadri-paresis and unconsciousness for previous three years prior to presentation. Prior to admission, he had been received anticonvulsants, but his symptoms showed no improvement. Neurological examination revealed hyper-reflexia of his left lower extremity and moderate decrease of sense of pain, temperature,(More)
The study concerned the effect of ascorbate on the contractile response induced by DMPP in the guinea-pig ileal longitudinal muscle. At 0.5-10 mM, sodium ascorbate shifted the dose-response curve for DMPP to the left and enhanced the maximum contraction. On the other hand, in the presence of ascorbate, the high potassium (40 mM)-induced contraction was not(More)
The effects of adenosine on acetylcholine (ACh) release and calcium uptake were examined in a synaptosomal fraction prepared from guinea-pig ileum myenteric plexus-longitudinal muscle. A high concentration of potassium (40 mM) and electrical pulses (ES:10Hz) caused a marked increase in the output of [3H]ACh from [3H]choline-preloaded crude synaptosomes.(More)
Regional cerebral blood flow (rCBF) was measured in 49 patients with surgically treated hypertensive intracerebral hemorrhage (putaminal hemorrhage 27: thalamic hemorrhage 22). The hematoma evacuation was performed within 14 days after the hemorrhage. For the measurement of rCBF, the intracarotid xenon-133 injection method was used. Two rCBF studies were(More)
The sites of presynaptic actions of adenosine on electrically stimulated longitudinal muscle strip of guinea pig ileum were studied with a special dual organ bath. Local stimulation (0.1 Hz) of the anal part of the strip induced a twitch response in the stimulated part and in the non-stimulated oral part; both of these twitch responses were depressed by an(More)
