Aedes (Stegomyia) albopictus (Skuse, 1894) larvae were recorded for the first time in the internodes of bamboo cuts found in the Atlantic Forest in the State of Paraná, Brazil. The bamboo, Bambusa sp., was introduced in the area of Imbucuí-Mirim town, across the municipal district of Paranaguá and towards the interior of the Atlantic Forest. A total of 251 larvae of Aedes albopictus (37.9%), Culex (Microculex) spp. (13.9%), Limatus durhami Theobald, 1901 (39.8%), Toxorhynchites sp. (0.4%) and Wyeomyia spp. (8.0%) were collected from bamboo internodes filled with rain and from the terrestrial Bromeliaceae and epiphytas found near the bamboo bushes. Aedes albopictus was found in bamboo internodes containing 30 to 254 ml of rain, sometimes coexisting with Li. durhami. Borders of forest ecosystems should be characterized as risk areas for arbovirosis transmission, since they sustain the circulation of vertebrates and arthropodal hematophagus, not only in the wild but also in the anthropic areas.

The public perception of the EU in Spain varies greatly. The most positive aspects of Spanish membership are associated with the consolidation of democracy, economic growth, the introduction of the euro, the growth in employment and structural and cohesion funds, the increase in the female participation rate, and the equal opportunities policies. The analysts are in favour of common objectives in the employment policy and multi-level government. The less positive aspects of the EU are the risks of losing social protection and loss of employment in some sectors due to mergers of multinationals and delocalization of companies towards Eastern Europe. The continuous demands for reform of the welfare state, the toughening of the conditions of access to social benefit and the reform of the labour market are also seen as problematic issues. Risks of competitive cuts and social dumping.

Studies have been carried out on the method of Britton and Silvette modified by Reinecke and Kendall, for the evaluation of cortico-adrenal extracts, based on the deposition of glycogen in the liver of adrenaletomized rats. The test was performed in a total of 180 normal and adrenalectomized rats. The extracts tested were: a) an aqueous extract of cortico-adrenal cortex prepared by the Swingle and Pfiffner technique; b) the same extract added with ascorbic acid (Supracortin Labor); c) desoxycorticosterone acetate (Percortol Ciba and Syncortyl Roussell). Male rats were used, ranging from 40-200g, fed since the 18 th days old with a special diet, in which they were maintained until the day before the injection. Adrenalectomy was performed under urethane anesthesia. The fourth day after operation, food was removed and they were fasted for 24 hours. In the morning of the fifth day, injections of the material to be assayed were given at hourly and two hours intervals, during four to eight hours. One or two hours after the last injection, the animals were sacrified, the livers removed and dropped into a hot 30% solution of potassium hydroxide, and worked by Good, Kramer and Somogyi method. The glycogen was calculated as milligrams per lOOg of body and liver weight. The results obtained are shown in the tables I, II, and III. When several dosages of the same sample of extract were made (5 animals each dose), the amount of glycogen deposited in the liver per lOOg of body and liver weight, was found to be a positive function of the dose injected. The graph 2, shows these results. The synthetic compounds were ineffective. Our results are in agreement with those of Reinecke and Kendall and of Olson et al.
