Érica Alves Gonzáles Vidal / Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências da Terra, Programa de Pós-Graduação em Sistemas Costeiros e Oceânicos. Defesa: Pontal do Paraná, 26/04/2013 / Inclui referências / Resumo: O polvo comum Octopus vulgaris tem se tornado um dos cefalópodes mais estudados, devido ao seu alto valor comercial e à crescente demanda como recurso marinho em muitos países. O estudo das relações entre sua estrutura populacional e os fatores ambientais que a determinam é de fundamental importância para um maior conhecimento de sua ecologia, possibilitando a criação de medidas de conservação e manejo eficazes. Devido à presença de O. vulgaris na Marina Ponta do Poço (25°32?822?S; 48°23?283?O), dentro do Complexo Estuarino de Paranaguá e a falta de informações sobre sua dinâmica populacional, o presente estudo teve por objetivo realizar uma descrição hidrográfica do local, determinar a distribuição e abundância relativa de paralarvas, densidade de juvenis e adultos, proporção sexual e determinar o estágio de maturação gonadal dos indivíduos. Entre agosto de 2012 e janeiro de 2013, a temperatura da água variou de 19 a 28 °C e a salinidade entre 23 e 34. As velocidades de corrente tiveram máximas de 120 cm s-1 na maré vazante e 73 cm s-1 durante a enchente. A densidade de paralarvas variou entre 0 e 0,033 ind. m-3, e durante os mergulhos para o censo visual, foi estimada uma abundância relativa de polvos de 0 a 0,023 ind. m-2. Machos e fêmeas não apresentaram diferenças significativas quanto às médias de peso, comprimento do manto e distância entre os olhos, e as variáveis biométricas foram altamente correlacionadas entre si. A proporção sexual não diferiu significativamente de 1:1, e o estágio III (maturo) foi o mais frequente na primavera, sendo substituído pelos estágios I (imaturo) e II (em maturação) no verão. Os resultados mostraram que na primavera e verão há uma agregação reprodutiva de O. vulgaris na Marina Ponta do Poço, local que oferece condições favoráveis em termos de disponibilidade de abrigo e alimento, propiciando a ocorrência desde juvenis imaturos, adultos maturos, desova e eclosão das paralarvas. Além disso, as características hidrográficas permitem uma ampla dispersão de paralarvas, favorecendo uma distribuição ainda maior de O. vulgaris no Complexo Estuarino de Paranaguá, fundamental para a manutenção da população de polvos na região. Palavras-chave: Octopus vulgaris, estrutura populacional, abundância, paralarva, características hidrográficas. / Abstract: The common octopus Octopus vulgaris has become one of the most studied and well known cephalopod species due to its high commercial value and the rising market demand for this marine resource in many countries. The study of the relationship between O. vulgaris population structure and the environmental factors which determine it is fundamental for a better understanding of the ecology of the species, allowing for the creation of effective measures for its conservation and management. Given the presence of O. vulgaris in the Ponta do Poço Marina (25°32?822?S; 48°23?283?O), inside the Paranaguá Estuarine Complex, and the lack of information on its population dynamics on the coast of Paraná, this study presents a hydrographic description for the named location; an estimation of paralarval abundance; and data on juvenile and adult density, sexual proportion, biometric measurements, and individual gonadal maturation stage. Water mean temperature varied from 19 to 28 °C between August 2012 and January 2013, and salinity varied between 23 and 34. Current speed reached a maximum of 120 and 73 cm s- 1 during ebb and flood tides, respectively. Paralarval density varied from 0 to 0.033 ind. m- 3, and during visual census through SCUBA diving the relative abundance of juveniles and adults was estimated from 0 to 0.023 ind. m-2. Males and females did not show significant difference as to the mean values in weight, mantle length, and distance between the eyes, and the biometric variables were highly correlated between themselves. The sexual proportion did not differ significantly from 1:1, and the stage III (mature) was the most frequently seen during spring, while stages I (immature) and II (maturing) were the most frequent during summer. The results show that there is a reproductive aggregation of O. vulgaris at the Marina Ponta do Poço during spring and summer, a place which offers favorable conditions in terms of shelter and food availability, favoring the occurrence since immature juveniles, mature adults, spawning and paralarval hatching. Moreover, the hydrographic characteristics allow a wide dispersion of the paralarvae, providing a great distribution of O. vulgaris in Paranaguá Estuarine Complex, which is essential to maintain the population of octopuses in the region. Keywords: Octopus vulgaris, population structure, abundance, paralarvae, hydrographic characteristics.

M.Tech. / Psoriasis vulgaris (plaque psoriasis) is a chronic recurring inflammatory skin disease that manifests most commonly as well-circumscribed, erythematous papules and plaques of varying sizes, covered with silvery scales (Beers et al., 2010). The condition itself is considered to be difficult to treat and manage by many types of healthcare practitioners, due in part to its unknown aetiology/trigger and partly due to the nature of the disease itself (Medonça and Burden, 2003). The aim of this study was to ascertain the effects of a Homoeopathic complex remedy on psoriasis. A group of twenty seven participants completed the study. Participants were of both sexes, had to be between the ages of 18 and 65 and had to have been previously diagnosed with plaque psoriasis. The study was conducted over four consultations, two weeks apart, over a six week period. The study followed a double-blind, placebo controlled format. Participants were grouped into matching pairs in terms of age and severity of disease and were then randomly assigned into either the treatment or placebo group for the study duration. Participants were evaluated at each consultation using the three primary assessment tools, namely: the psoriasis area and severity index (PASI) used to assess erythema, thickness and scaling of lesions; the psoriasis disability index questionnaire (PDI), a subjective participant-orientated evaluation of the psychological impact of the disease and the 5-D itch scale used to quantitatively rate the subjective experience of pruritus. The secondary tools used at each consultation were for monitoring purposes only and were used to determine: changes in selected lesion area, as well as the effects of the intervention on the total body surface area (TBSA) affected by psoriasis. The TBSA tool was also used to determine whether new lesions developed during the study period. Using non-parametric analyses, the results of the study demonstrated statistically significant improvement in three of the five variables tested. This includes improvement in: lesion appearance (erythema, scaling and thickness) as determined by PASI; improved psychological experience of the disease quantified by PDI and improvement in the degree of pruritus. It was noted that non-parametric analyses also showed improvement in lesion area. However, lesion area measurement was a secondary tool used for monitoring purposes and it was noted that the use of the tool demonstrated short-comings with regards to consistency and reliability. Parametric analyses showed improvement of statistical significance in one of the five variables tested, namely that of pruritus levels as determined by the 5-D itch scale. It was concluded from this study that the homoeopathic complex remedy was found to be effective in the treatment of certain symptoms of psoriasis and as such should be considered as an adjunct therapy in its treatment.
