A nonparasitic lamprey in Japan, Lethenteron reissneri, stops feeding prior to the commencement of metamorphosis. Resumption of feeding cannot take place due to major alterations in the digestive system, including loss of the gall bladder (GB) and biliary tree in the liver. This degeneration of bile ducts is considered to depend on programmed cell death or(More)
BACKGROUND/PURPOSE A simple and objective method evaluating the bowel functions of patients with anorectal anomalies is necessary. The authors applied fecoflowmetry and saline enama test for patients with anorectal anomalies to evaluate the fecodynamics and anorectal motilities in these children. METHODS The bowel functions of 16 patients who underwent(More)
Idiopathic chronic constipation (ICC) is one of the most common clinical conditions in children. The pathophysiology is multifactorial and differs from case to case. To investigate the relationship between anorectal motility (ARM) and clinical course in children with ICC, anorectal function was evaluated using fecoflowmetry in nine children aged 2–14 years(More)
Activated hepatic stellate cells (HSCs) play crucial roles in liver fibrosis. In the course of liver injury, HSCs, which reside in perisinusoidal spaces and lose lipid droplets, morphologically change into a myofibroblastic phenotype and acquire an increased proliferation activity in what is known as the activated state. We have investigated therapeutic(More)
BACKGROUND Arginine becomes an essential amino acid after massive resection of the small bowel as a result of decreased biosynthesis of citrulline in the remaining small bowel. It is also reported that nitric oxide (NO) is synthesized from l-arginine by NO synthase (NOS), and NO is involved in the regulation of blood flow in the kidney. The authors observed(More)
A Z-shaped skin incision applying Kraissl's lines for a thoracotomy is presented herein. The center of the Z-shape is located on the intercostal space of the thoracotomy. Parallel Z-shaped lines are described on circular Kraissl's lines in the axillary region. The oblique cross-line of the Z-shape is drawn from the dorsal edge of the cranial line to the(More)
The present study was designed to assess the effectiveness of on-line plasma exchange (on-line P.E.) between septic infants and healthy adults using septic puppies. The plasma separation system consisted of a membrane plasma separator and a plasma treatment system, KM-9027 (Kurarey Co.) equipped with small 2 channel blood and plasma pumps. 5 X 10(9)(More)
Transforming growth factor (TGF) β is a pro-fibrotic cytokine. While three isoforms (TGF-β1, 2 and 3) are known, the functional differences between them are obscure. To investigate the roles of TGF-β isoforms during liver fibrogenesis, male Wistar rats were administrated carbon tetrachloride (CCl4) subcutaneously(More)
Four-week-old male Sprague-Dawley rats underwent a 90% small bowel resection. From the fourth day after surgery, they were divided into group 1 and 2, and pair-fed by elemental diets (0.8 kcal/mL, 50 mL/day) with L-arginine (n = 10) or L-glycine (n = 11) as an isonitrogenous and isoenergetic supplement for 3 weeks. They were compared with each other 3 weeks(More)
