The biological cycle of Caryophyllaeus brachycollis Janiszweska, 1953 (Cestoda carophyllaeidae) a parasite of Barbus meridionalis Risso, 1826 in the south of France]

Caryophyllaeus brachycollis Janiszweska, 1953 has been found for the first time in France in Barbus meridionalis Risso, 1926. Experimentally, the procercoid develops in Tubifex sp. and never in Limnodrilus sp. The different possibilities of life cycle of C. brachycollis in Europe have been compared.     

Effect of Dietary Lipids (Soybean Lecithin and Triacylglycerol) on Hepatic F-Actin Microfilaments in Cyclosporine A-Treated Rats

We studied and quantified the effect of cyclosporine A on hepatic F-actin on bile canalicular and basolateral membranes in rats fed either soybean lecithin, triacylglycerol-enriched diet, or low-fat diet by means of confocal laser scanning microscopy imaging. The phalloidin–FITC staining of F-actin was quite normal in the lecithin–cyclosporine A group but decreased significantly in the other cyclosporine A-treated groups (by 40% and 25% of control in triacylglycerol–cyclosporine A and cyclosporine A groups, respectively). The alteration of F-actin by cyclosporine A, related to cholestasis evidenced by a decrease in bile salt secretion, was prevented by dietary soybean lecithin and amplified by dietary soybean triacylglycerol.     

Esophageal-atrial fistula

We report an unusual case of an esophageal-atrial fistula in a patient with CREST (calcinosis, Raynaud's phenomenon, esophagitis, sclerodactyly, telangiectasia) variant of scleroderma. An ulcer in Barrett's esophagus perforated into the left atrium and led to systemic embolization and cerebral abscess. A review of similar reports of esophageal-atrial fistula reveals a symptom complex that includes chronic esophageal pathology, gastrointestinal bleeding, and neurological signs. An antemortem diagnosis has never been made.
