An operated case of cerebral paragonimiasis miyazakii was reported. A 25-year-old man was admitted to our hospital on Jan. 25, 1982, because of weakness, sensory disorder and focal convulsion of the right upper limb. He complained of slight headache but had no sign of meningeal irritation nor inflammation. CT scan revealed a left parietal low density mass with irregular ring-like contrast enhancement. Left carotid angiogram showed stretched arteries around the mass. Laboratory findings were normal except for eosinophilie (17%). Chest X-P was normal. Operation was performed under diagnosis of glioblastoma on Aug. 6, 1982. The tumor was well-circumscribed and had a firm capsule which containing necrotic substance. The tumor was removed totally and the bone flap was also removed since slight brain swelling was seen. Histologically it proved to be a granuloma and four eggs of helminth were found in the necrotic tissue. Post operative state of the patient was satisfactory and cranioplasty was performed 3 weeks later. On Aug. 31, he began to complain of chest pain, cough and hemosputum, and chest X-P disclosed a nodular shadow in the lower lobe of the right lung. Paragonimiasis was strongly suspected because he had a history of having three fresh-water crabs (Potamon dehaani) 18 months before. But not egg was found in either sputum nor stool. Skin test with paragonimus westermani antigen was highly positive.(ABSTRACT TRUNCATED AT 250 WORDS)

Previously, we identified noscapine as a small molecule inhibitor of the hypoxia-inducible factor-1 pathway in hypoxic human glioma cells and human umbilical vein endothelial cells. Noscapine is a nontoxic ingredient in cough medicine currently used in clinical trials for patients with non-Hodgkin's lymphoma or chronic lymphocytic leukemia to assess antitumor efficacy. Here, we have evaluated the sensitivity of four human glioma cell lines to noscapine-induced apoptosis. Noscapine was a potent inhibitor of proliferation and inducer of apoptosis. Induction of apoptosis was associated with activation of the c-jun N-terminal kinase signaling pathway concomitant with inactivation of the extracellular signal regulated kinase signaling pathway and phosphorylation of the antiapoptotic protein Bcl-2. Noscapine-induced apoptosis was associated with the release of mitochondrial proteins apoptosis-inducing factor (AIF) and/or cytochrome c. In some glioma cell lines, only AIF release occurred without cytochrome c release or poly (ADP-ribose) polymerase cleavage. Knock-down of AIF decreased noscapine-induced apoptosis. Our results suggest the potential importance of noscapine as a novel agent for use in patients with glioblastoma owing to its low toxicity profile and its potent anticancer activity.

Thymus longicaulis C. Presl. (Lamiaceae) is a small aromatic perennial herb typical of the Illyric-Mediterranean flora, traditionally used as remedy for cold, flu, cough, nephritis and abdominal pain. In order to carry out a thorough chemical and biological screening of the plant and to explore phenophases influence on its polyphenol content, samples of the plant were collected at different phases during its life cycle (July/October 2012 and January/April 2013). Each sample, previously extracted using a hydroalcoholic solution, was phytochemically analyzed for its metabolic constitution applying LC-DAD-ESI-MS/MS techniques. Although identified metabolites were differently concentrated at the various collection times, T. longicaulis leaf extracts were mainly constituted by low molecular weight phenols, and flavonoids. Rosmarinic acid was found as the main metabolite in Oct12 sample. Chemopreventive efficacy of the investigated extracts, by means of their anti-inflammatory, cytotoxic and antioxidant activities, was assessed. To this purpose, each extract underwent an extensive screening towards five human cell lines: CCRF-CEM (leukemia); U251 (glioblastoma); MDA-MB-231 (breast cancer); HCT-116 (colon cancer) and MRC-5 (lung fibroblasts) through XTT [2,3bis(2-metoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H tetrazolium hydroxide] test. The ability of the extracts to counteract cyclooxygenase-2 (COX-2) expression was also evaluated by COX-2 expression assay in human THP-1 monocyte-derived macrophages. COX-2 inhibition could represent a valuable anticancer strategy as it is associated with carcinogenesis and over-expressed in a variety of human malignancies. Oct12 extract, which was particularly rich in rosmarinic acid and methylapigenin, exhibited a strong antioxidant and anti-inflammatory effectiveness.
