[Thyroid function in patients with Yusho].

To evaluate chronic effect of polychlorinated biphenyl (PCB) on thyroid functions, thyroid hormone levels were studied in 115 patients with Yusho in 2002. Serum level of thyroid stimulating hormone (TSH) was elevated in 13 cases (11.3%). All of them showed normal triiodothyronine (T3) and thyroxine (T4) levels, and regarded as latent hypothyroidism. There were no significant correlations between blood PCB concentrations and TSH levels, T3 levels or T4 levels. We conclude that abnormality of TSH levels in patients with Yusho is frequent, but it may not be associated with blood PCB concentration.

Evidence-based clinical practice guidelines for acute pancreatitis: proposals.

BACKGROUND/PURPOSE: To provide a framework for clinicians to manage acute pancreatitis, evidence-based guidelines have been developed by the Japanese Society of Abdominal Emergency Medicine. METHODS: Evidence was collected by a systematic search of MEDLINE and Japana Centra Revuo Medicina. A total of 1348 papers were reviewed and levels of evidence were assessed. Practical recommendations were also graded. RESULTS: The present guidelines consist of introductions, a summary of recommendations, practice algorithms, definitions, epidemiology, diagnosis, severity assessment, and therapy. The main points of recommendation in these guidelines are: (1) measuring lipase for the diagnosis of acute pancreatitis (recommendation grade [RG], A). (2) The Severity of acute pancreatitis should be assessed using a scoring system, such as that of the Japanese Ministry of Health and Welfare or Acute Physiology and Chronic Health Evaluation (APACHE) II (RG, A). (3) Enhanced computed tomography (CT) should be used for assessment of degree of pancreatic necrosis and inflammation (RG, B). (4) Prophylactic antibiotic administration should be used for severe pancreatitis (RG, A), but not for mild to moderate pancreatitis (RG, D). (5) Gabexate mesilate should be used for severe pancreatitis (RG, B). (6) Enteral feeding should be used for all pancreatitis (RG, B). (7) Continuous hemodiafiltration and continuous arterial infusion of proteinase inhibitor and antibiotics may be of benefit (RG, C). (8) Fine-needle aspiration should be done for the diagnosis of infectious pancreatic necrosis, and if positive, necrosectomy is indicated (RG, A). CONCLUSIONS: These guidelines provide useful information for physicians to manage this troublesome disease.

Importance of N-linked sugar residues in the development of Auerbach's plexus in the rat colon: a lectin histochemical study.

The lectin-binding patterns in Auerbach's plexus in the distal portions of the rat colon from 15- to 21-day-old foetuses, newborns, and adults were examined by light and electron microscopy using 16 different lectins (ConA, RCA-1, WGA, PNA, SBA, UEA-1, DBA, LCA, PHA-L, DSA, GS-1, VVA, MPA, BPA, MAA, and PSA). The binding of ConA was shown to increase after day 19 of gestation in parallel with differentiation of Auerbach's plexus, whereas the staining intensity for DSA and RCA-1 increased after day 17 of gestation in accordance with the appearance of the plexus. At the electron microscopical level, DSA binding sites were observed to be localized mainly in the plasma membrane, Golgi apparatus, and nuclear membrane of nerve cells. Positive sites were also observed in the axolemma and in the plasma membrane of nerve cell processes, Schwann cells, and the surrounding smooth muscle cells. PSA, PHA-L, LCA, and WGA showed constant staining during the development after day 15 of gestation. Other lectins, most of which are specific for O-glycosidic mucin-type sugar residues, were essentially negative throughout the developmental stages. Moreover, N-glycanase digestion significantly diminished the positive reactions. N-linked oligosaccharides may thus play important roles in the development and maturation of the Auerbach's plexus, and may be involved in the developmental defect of the plexus, e.g. as occurs in Hirschsprung's disease.
