Abstract
This study investigated (1) protective effects of a commercially available mycotoxin adsorbent (MA) and (2) endocrine effects of in vivo exposure to zearalenone (ZEA) in cattle. The sample included a Japanese Black female cattle herd (MYT herd) that displayed persistently high urinary ZEA concentrations. A second herd (NM herd) was used as a control. Three groups from each herd were assessed: MX (n=6; MA mixed with concentrate), TD (n=6; MA applied as topdressing with the concentrate), and a positive control (n=6; no MA application). Urine and blood samples were collected at the start of MA supplementation (day 0), on the final day of supplementation (day 16), and on the final day of the sampling period (day 58 for MYT herd and day 50 for NM herd). Urinary ZEA concentrations (pg/mg of creatinine) were measured by ELISA and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Haematological and serum biochemical analyses were performed to monitor hepatic, renal, nutritional, and mineral intake statuses. Ovulation status was assessed by progesterone (P4) and antral follicle population by anti-Müllerian hormone (AMH) levels. The urinary concentrations of ZEA and its metabolites in the MX and TD groups were significantly lower (P<0.05) at day 16 compared with the control group, as measured by LC-MS/MS. The valid ratio of AMH-positive (≯0.08 ng/ml) cattle was significantly higher in the NM herd than in the MYT herd without affecting the P4-positive (≯3 ng/ml) ratio, suggesting different populations of antral follicles. Significant differences were also observed between the MX and the control in aspartate aminotransferase and γ-glutamyltransferase at day 58, suggesting preventive effects of MA supplementation. Our field trial indicated that MA supplementation of a ZEA-contaminated diet has beneficial effects in reducing ZEA absorption from the intestine of cattle, maintaining endocrine homeostasis and reversing hepatic effects.

Abstract
OBJECTIVES To determine the risk factors for the development of thyroid diseases during interferon-alpha therapy, we analyzed the patients with chronic hepatitis C who were treated with interferon-alpha. METHODS One hundred nine patients with chronic hepatitis C (77 men and 32 women, ages 20-72 yr) were treated with interferon-alpha (alpha, 48; alpha 2a, 38; alpha 2b, 23) for 14-40 wk. Thyroid function tests and seven autoantibodies were assessed at the beginning and end of interferon-alpha therapy, and every other month. A logistic multiple regression model was used in the statistical analysis of risk factors for development of thyroid diseases. RESULTS Among the 106 patients with normal pretreatment thyroid function tests, nine patients (three men and six women, ages 33-62 yr) developed thyroid diseases. However, among three patients with abnormal thyroid function tests, exacerbation of thyroid disease was not observed during interferon-alpha therapy. Logistic multiple regression model revealed that positivity for microsome antibody was a significant risk factor for the development of thyroid disease (p < 0.0001, chi 2 = 20.18). Actually, compared to patients without microsome antibody at the beginning of therapy, the incidence of thyroid diseases in the patients with pretreatment microsome antibody was very high: 3.3% (3/99) versus 60% (6/10), respectively. Six patients developed hyperthyroidism and three patients developed hypothyroidism. The patients with hyperthyroidism had atypical clinical features. CONCLUSION Our study revealed that positivity for microsome antibody at the beginning of interferon-alpha therapy is a risk factor for thyroid dysfunction.

Abstract
An association between primary sclerosing cholangitis (PSC) and chronic ulcerative colitis (CUC) is well known in Western countries, but there have been no reports on this association in Japan. We reviewed 163 consecutive CUC patients (91 males and 72 females) diagnosed from 1984 to 1990 at Tokyo Women's Medical College. Abnormal liver function tests were found in 42 patients with CUC (25.8%), but chronic liver disease was only diagnosed in seven patients (4.3%). Among these seven patients, there were four with PSC, one with small-duct PSC, one with transfusion-associated chronic hepatitis and one with Type B liver cirrhosis. No relationship was found between the documented colonic manifestations of CUC and the presence of PSC. The four PSC patients did not have a longer history of CUC at the time of diagnosis of PSC than CUC patients without PSC. At the time of PSC diagnosis, two patients were asymptomatic, one presented with right upper quadrant pain, and the other had fatigue. Three patients were diagnosed as having CUC before the onset of PSC (range 2-13 years), and the other patient had both diseases simultaneously. All four had a good prognosis. Thus PSC was the most common chronic liver disease associated with CUC in our series, and it was present in all our CUC patients with alkaline phosphatase levels exceeding twice the upper limit of normal and mild transaminase elevation.
