ABSTRACT
ABSTRACT The objective of this study was to assess variations of the condition factor (K1) in relation to the gonadosomatic- RGS and energy reserves (hepatosomatic - RWL and liposomatic - RFB relations) of Leptodactylus macrosternum and their relationship to climate variation in the Northeast of Brazil, Caatinga area, state of Paraiba. The animals were captured fortnightly through active collecting, between January and December 2013. Significant differences were observed in the monthly variations of K1, RGS and RFB indices in male and female L. macrosternum over the months of collection. In males, K1 showed no significant relationship with the other variables. In females, RGS values only show notable correlations with RWF and K1 values. K1 values showed significant correlations with all other weight and length ratios. Climate change in the HFOB region showed significant relationships with the variation of the indexes evaluated, with the exception of RWF. The variation of K1, RGS, RWL and RFB values over the months of collection as well as their relation with the local climatic variation, showed a brief reproductive activity for the species.

El cuerpo adiposo bucal es de gran utilidad en el tratamiento de defectos intraorales. La técnica descrita ha demostrado ser más sencilla,mejor tolerada y con menor tasa de complicaciones, que otras técnicas descriptas anteriormente. Por estos motivos es importante considerar a este elemento anatómico al momento de cerrar comunicaciones bucosinusales. El presente trabajo presenta la utilizacióndel mismo en tres casos de comunicación buco sinusal, todas de etilogía odontógena.
Fat body bucal is very useful when treating intraoral defects. The technique has proven to be simpler, more tolerable and shows a lowercomplication rate than the utilization of other techniques previously described. This is why it's important to consider this anatomic element when closing communication between oral and nasal cavities. We present the utilization of said element in three cases of communication between cavities, all of them of odontogenic etiology.

The insect fat body plays major roles in the intermediary metabolism, in the storage and transport of haemolymph compounds and in the innate immunity. Here, the overall structure of the fat body of five species of mosquitoes (Aedes albopictus, Aedes fluviatilis, Culex quinquefasciatus, Anopheles aquasalis and Anopheles darlingi) was compared through light, scanning and transmission electron microscopy. Generally for mosquitoes, the fat body consists of lobes projecting into the haemocoel and is formed by great cell masses consisting of trophocytes and oenocytes. Trophocytes are rich in lipid droplets and protein granules. Interestingly, brown pigment granules, likely ommochromes, were found exclusively in the trophocytes located within the thorax and near the dorsal integument of Anopheles, which is suggestive of the role these cells play in detoxification via ommochrome storage. This study provides a detailed comparative analysis of the fat body in five different mosquito species and represents a significant contribution towards the understanding of the structural-functional relationships associated with this organ.
