    Notes: Summary Streptozotocin diabetic rats have larger kidneys than non-diabetic rats. In the present study the rate of kidney growth during the first seven days of diabetes was correlated with the blood glucose concentration. Over a wide range of blood glucose concentrations (116–340 mg/100 ml) the kidney weight, protein content and protein/DNA ratio were closely correlated with the glucose values.

    Description / Table of Contents: Zusammenfassung Die vier Porensensillen des Maxillarpalpus von Agrion and Ischnura besitzen zwei (Sensillum Typ A), beziehungsweise fünf (Sensillum Typ B) bipolare Rezeptorzellen. Distal werden ihre Dendriten von der Dendritenscheide und dem Porusrohr umschlossen. Die Dendriteninnenglieder inserieren seitlich an den Perikarya. Die Rezeptorzellen jedes Sensillums sind von drei Hüllzellen und drei voneinander getrennten Rezeptorlymphräumen umschlossen. Rezeptorlymphraum l und 3 haben durch das Porusrohr, beziehungsweise durch das Porenkanalsystem der Cuticula Verbindung nach außen. Alle drei Hüllzellen zeigen apikal mikrovillusartige Membranstrukturen; außerdem besitzen sie je zwei Centriolen in Tandemstellung. Die Feinstruktur der Porensensillen wird mit der ähnlicher Arthropodensensillen verglichen. Funktionelle und phylogenetische Aspekte werden diskutiert.
    Notes: Summary The four single-pore sensilla on the maxillary palp of Agrion and Ischnura possess two bipolar sensory cells for A-sensilla and five for B-sensilla. Distally, their dendrites are enclosed by a dendritic sheath and a pore tube. The dendritic tips have access to the outside via the opening of the pore tube. The inner dendritic segments join the receptor cell bodies laterally. The receptor cells of each sensillum are enveloped by three sheath cells and three receptor lymph cavities. Receptor lymph cavity 1 and 3 are connected with the outside by the pore tube and a minute canal system in the cuticle, respectively. All three sheath cells show microvilluslike processes of the apical membrane. Moreover, all sheath cells contain two centrioles in tandem arrangement. The structure of the single-pore sensilla is compared with that of similar sensilla of other arthropods. Functional and phylogenetic aspects are discussed.
