When AR42J cells, an amylase-secreting pancreatic exocrine cell line, were treated with activin A, cells extended neuritelike processes, and, concomitantly, amylase-containing vesicles disappeared. Immunofluorescence and immunoelectron microscopy revealed that these processes had neurite-specific cytoskeletal architectures: neurofilaments and microtubule(More)
We examined the role of opioid receptor subtypes in the contraction and release of acetylcholine (ACh) and norepinephrine in longitudinal muscle-myenteric plexus preparations of the guinea pig ileum. [D-Ala2, N-Me-Phe4, Gly5-ol]enkephalin (DAMGO) (10(-8) to 10(-5) M) inhibited the contraction and the release of ACh evoked by 0.2 and 1 Hz of electrical(More)
Eine neue Messmethode für Durchblutungsmessungen besteht darin, dass selbstgeregelter Strom mit Hilfe des Rückkopplungsregelungssystems für die Heizung gebraucht wird. Mit dieser Methode wird der Temperaturunterschied zwischen den geheizten und den gekühlten Kontaktplatten ganz gering und konstant gehalten, so dass der Effekt der lokalen Wärmeakkumulation,(More)
Befunde bei Hunden mittels histochemischer Fluoreszenz erbringen den Nachweis des Eindringens von Catecholaminfluoreszenz-Nervenfasern in die glatten Muskelschichten der Media in der Arteria dorsalis pedis. Die Ergebnisse sind histochemisch, pharmakologisch und chirurgisch unterbaut worden.
During the 7 years from 1980 to 1986, 2860 cases of bladder tumors were registered in the Tokai Urological Cancer Registry. Among the 2860 cases, 2304 cases were selected from the registered cases for the present study. The 5-year relative (actual) survival rates were 73.8% (61.9%) of all patients; 48.9% (42.4%) in those with malignant neoplasma of urinary(More)
Oral co-administration of folic acid (pteroylglutamic acid, PteGlu) potentiates the decrease of plasma 5-methyltetrahydrofolic acid (5-CH3-H4PteGlu) concentration induced by pyrimethamine (PYR) in rats. To clarify the mechanisms of this potentiated decrease, we examined the effects of PteGlu and PYR on intestinal absorption of folates in rat jejunum loops,(More)
The aim of this study was (1) to fabricate non-woven meshes from a biodegradable polymer, poly(γ-benzylL-glutamate), by electrospinning and subsequent hydrolysis of the ester bond on the polymer side-chain in an aqueous solution of NaOH, creating surface carboxyl groups on the fibers, and (2) to determine the effect of hydrolysis time on water wettability(More)
