Avaliaram-se diferentes concentrações de sais do meio MS (Murashige & Skoog, 1962), freqüência de subcultivos e adição de ácido ascórbico ao meio de cultura, objetivando o controle da oxidação de explantes de bananeira-'Prata' (Musa AAB) na fase de estabelecimento. Os tratamentos constituíram-se das diluições dos sais do meio MS (100%, 50% e 33,33%), subcultivos (a cada 7 dias, a cada 14 dias e a cada 28 dias) e ácido ascórbico (0 e 25 mg L-1). O delineamento experimental foi inteiramente casualizado, cujos tratamentos foram arranjados em um fatorial 3 x 2 x 2. Utilizaram-se 15 repetições. As avaliações relativas à massa da matéria fresca, altura e oxidação foram feitas aos 28 dias após a inoculação. Quando o período de subcultivos foi maior (28 dias), o crescimento em massa da matéria fresca foi reduzido em função da redução da concentração de sais do meio MS. Para meios de cultura menos concentrados e freqüência maiores de subcultivos, não houve necessidade da adição do ácido ascórbico para a redução do escurecimento e houve uma tendência de maior crescimento em massa dos explantes.

OBJECTIVE: Thrombocytosis is an adverse prognostic factor in many types of cancer. We investigated if pre-treatment increased platelet counts provide prognostic information specifically in patients with stage III and IV serous ovarian cancer which is the most common clinical presentation of ovarian cancer. METHODS: Platelet number on diagnosis of stage III and IV serous ovarian adenocarcinoma was evaluated in 91 patients for whom there were complete follow-up data on progression and survival. Survival and progression free survival of patients with normal platelet counts (150-350 ×10(9)/L) was compared with that of patients with thrombocytosis (>350×10(9)/L) by χ(2) and logrank tests. RESULTS: The median age of the patients was 66 years-old. From the 91 patients, 52 (57.1%) had normal platelet counts (median, 273×10(9)/L; range, 153-350) at diagnosis of their disease and 39 patients (42.9%) had thrombocytosis (median, 463×10(9)/L; range, 354-631). In the group of patients with normal platelet counts, 24 of the 52 patients had died with a median survival of 43 months (range, 3-100). In the group of patients with thrombocytosis, 24 of the 39 patients had died with a median survival of 23 months (range, 4-79). In the entire group of 91 patients there was a statistically significant difference of the overall survival and progression-free survival between the two groups (logrank test P=0.02 and P=0.007, respectively). CONCLUSION: In this retrospective analysis of stage III and IV ovarian cancer patients, thrombocytosis at the time of diagnosis had prognostic value regarding overall survival and progression-free survival.

En connexion avec un travail monographique sur la vallée de Ribes (Pyrénées orientales), l'auteur décrit huit associations nouvelles: Veronico (urticifoliae)-Betuletum, forêt acidophile et hygrophile propre aux versants très ombragés; Allio-Calamagrostietum arundinaceae, mégaphorbiée de l'alliance Calamagrostion; Bellardiochloo-Festucetum nigrescentis, pelouse' très acidophile peuplant les pentes rocheuses et chaudes de l'étage subalpin; Rhinantho (mediterranei)-Trisetetum flavescentis et Astrantio-Avenuletum pubescentis, prairies de fauche, la première ( al. Arrhenatherion') très étendue dans tout l'étage montagnard, la deuxième (al. Polygono-Trisetion) assez localisée dans le montagnard supérieur ; Gentianô' (luteae)-Trisetetum, type de prairie faisant le passage entre l'Arrhenatherion et le Mesobromion; et Swertio-Caricetum nigrae, bas marais d'haute montagne, silicicole mais pas nettement acidophile. Au sein de l'association Prunello-Sarothamnetum, l'auteur propose deux nouvelles sous-associations: buxetosum, la plus commune dans l'étage montagnard, et genistetosum purgantis, en contact avec le Genistion purgantis.
