    Notes: Samples of maize seed were obtained from countries in Central America, Africa and Asia and assessed for fungal infection. Fusarium spp. were the largest single group of fungi present, and from these Fusarium moniliforme was the species most frequently isolated. Other fungi, including Stenocarpella (Diplodia) maydis, S. macrospora and Acremonium strictum, were also present in significant numbers. Isolates of F. moniliforme were characterized for mating populations, using RAPDs, and a number of isolates, taken at random from those assigned to specific mating groups, were also confirmed by crossing. Isolates were also characterized for fusaric acid production and significant differences in fusaric acid production were detected between isolates from different countries and regions within countries. A detailed analysis of isolates from one country, Kenya, was undertaken. The importance of the pathogens is discussed in relation to human, animal and seed health and quarantine regulations, and plant breeding objectives.

    Notes: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by a progressive obliterating fibrosis of the intrahepatic and extrahepatic bile ducts. The pathogenesis of PSC is poorly understood but it is thought to be an immune-mediated disease. The optimal therapy which successfully improves symptoms, delays progression towards liver failure and transplantation and prevents the onset of cholangiocarcinoma remains elusive. Although current treatments are used to manage cholestasis and its consequences and some of the more general complications of the disease, none of the current therapeutic agents have been shown to retard and reverse the rate of disease progression. The role of cupruretics, corticosteroids, methotrexate, anti-fibrogenic agents and ursodeoxycholic acid in the treatment of PSC is reviewed. Orthotopic liver transplantation remains the only therapeutic option for advanced PSC but the timing of transplantation remains controversial and the possibility of recurrence of the disease in the graft is increasingly recognised. It is likely that greater insight into the pathogenetic mechanisms involved in PSC will allow therapy to be targetted more specifically at the biliary epithelium.

    Notes: Abstract Liver iron concentrations were determined in 60 alcoholics with liver disease of varying severity, 15 patients with untreated idiopathic hemochromatosis, and 16 control subjects with biliary tract disease. Mean liver iron concentrations (μg/100 mg dry weight) were significantly greater in the alcoholics (156.4±7.8 (sem);P〈0.05) and in patients with idiopathic hemochromatosis (2094.5±230.7;P〈0.01) than in control subjects (53.0±7.0). Liver iron concentrations of 〉140 μg/100 mg were found in 17 alcoholics (29%) and in all 15 patients with idiopathic hemochromatosis. Liver iron concentrations 〉1000 μg/100 mg were found in all patients with idiopathic hemochromatosis but in none of the alcoholics. In the alcoholics no relationship existed between liver iron concentrations and the amount of alcohol consumed daily, the length of the drinking history, the amount of beverage iron consumed daily, or the severity of the liver disease. Serum ferritin concentrations reflected iron stores in patients with hemochromatosis and in alcoholics with minimal liver disease. However, in alcoholics with significant liver disease serum ferritin concentrations did not reflect iron stores accurately, although with normal values iron overload is unlikely. Serum iron concentration and percentage saturation of total iron-binding capacity were of little value in assessing iron status in either alcoholics or patients with hemochromatosis. Measurement of the liver iron concentration clearly differentiates between alcoholics with significant siderosis and patients with idiopathic hemochromatosis.

    Notes: Abstract Total ferritin concentration was measured in sera of 30 patients with primary liver cell cancer (PLCC) and 33 patients with cirrhosis and compared with serum alpha-fetoprotein levels as a diagnostic marker of PLCC. Serum ferritin concentration was raised in 19 patients (63%) with PLCC and 11 patients (33%) with cirrhosis. The median level was significantly higher (P〈0.001) in the PLCC group (560 μg/liter) than in the cirrhotic group (137 μg/liter), although there was considerable overlap. Serum ferritin was posititively correlated with serum aminotransferase levels in the cirrhotic patients (r=0.53,P〈0.001), reflecting hepatic necrosis, but not in the PLCC patients. The concentration of ferritin binding to concanavalin A was measured in the sera of patients with elevated total serum ferritin. Although the proportion of bound ferritin was decreased in the majority of PLCC sera compared to controls (P〈0.001), there was overlap with the cirrhotic group, making it unlikely that this assay is useful in distinguishing a tumor-specific isoferritin. Serum alpha-fetoprotein levels were elevated in 21 patients (70%) with PLCC and proved to be a highly sensitive and specific test for PLCC. There was no relationship between the alpha-fetoprotein and serum ferritin concentrations. Serum ferritin is inferior to alpha-fetoprotein as an initial screening test for PLCC, but in alpha-fetoprotein-negative patients serum ferritin may have a role in monitoring therapy. Patients with cirrhosis with normal serum alpha-fetoprotein and ferritin concentrations are very unlikely to have PLCC.

    Notes: Abstract Ethyl nicotinate was found to be a potent attractant forThrips obscuratus in peaches and apricots. The male-to-female ratio in traps was 1∶8. The chemical was more attractive than ripe fruit, with peak catches at harvest. Season-long trapping showed the efficiency of the chemical compared to unbaited traps. The chemical remained attractive for at least 2 weeks when 50 μl were placed in open 2-ml vial caps. Various pyralids, geometrids (Lepidoptera), and chironomids (Diptera) were also attracted in low numbers to ethyl nicotinate.
