Paragonimiasis is a helminthic disease of carnivorous animals. Man is infected accidentally. It has a worldwide distribution but is mainly encountered in Southeast Asia, particularly in Korea. Other endemic areas include Africa and South America. Cerebral paragonimiasis is not rare, but pleuropulmonary manifestations are the most prevalent. They include hemoptysis (frequently rusty-colored), unilateral or bilateral pleural effusions, and pulmonary infiltrates or cavities. This constellation of symptoms often mimics those of tuberculosis. Cerebral and lung involvement has recently been investigated by CT-scan and NMR. The diagnosis is based on the identification of parasite eggs in sputum or feces, and on ELISA serology. The treatment of choice is praziquantel.

Aorto-bronchial fistula is a rare but associated with a height rare of mortality. Although most reported cases are secondary to infectious aneurysms, cases arising after surgery to correct congenital cardiovascular abnormalities have recently been described. We report the case of a 41-year-old patient with recurrent hemoptysis and a history of Fallot's tetralogy corrected in childhood. Given such a case of hemoptysis in a patient with a history of cardiovascular surgery, the correct diagnostic approach includes fiberoptic bronchoscopy, helicoidal CAT and/or NMR, and aortography. Diagnostic confirmation should be followed soon by corrective surgery.

Ligularia is mainly distributed in the western regions of China. Most of the species have been traditionally used in folk medicine for the treatment of hepatitis B, asthma, hemoptysis and pulmonary tuberculosis. In our continuation of research on antiviral components from traditional Chinese medicine, Ligularia atroviolacea was tested for inhibitory effects on hepatitis B virus (HBV). A bioassay-guided phytochemical examination of L. atroviolacea disclosed that its ethyl acetate extract, which was made up of two eremophilenolides, showed suppressive activity on the expression of HBV surface antigen (HBsAg) in the HepG2.2.15 cell line. Then a simple and effective preparative high-speed counter-current chromatography method was successfully developed for the isolation and purification of two main active metabolites, 8beta-hydroxyeremophil-3,7(11)-dien-12,8alpha;15,6alpha-diolide and 8beta-methoxyeremophil-3,7(11)-dien-12,8alpha;15,6alpha-diolide from the ethyl acetate extract of L. atroviolacea by a one-step separation using a two-phase solvent system composed of light petroleum (60-90 degrees C)-ethyl acetate-methanol-water (9:1:8:2, v/v/v). The chemical structures of the two eremophilenolides were identified by ESI-MS, (1)H-NMR and (13)C-NMR analysis. The anti-HBV activity of the two purified compounds was measured; both of them showed suppressive activity on the expression of HBsAg in the HepG2.2.15 cell line. The results support the continued and expanded exploitation and utilization of L. atroviolacea.
