Plumbago is a traditional medicinal plant in Ayurveda. The paper presents anatomical study of leaf, petiole, stem and root of two species of Plumbago namely P. zeylanica, P. auriculata and, its relevance in discrimination of these two species. Anatomical features of leaf which are of diagnostic value in delimitation of both taxa are outline of T. S.,shape and size of epidermal cells, presence of sclerenchyma surrounding the vascular bundles, number of tannins cells. Characters of taxonomic significance in petiole anatomy are outline of T. S, presence of trichomes, shape and size of epidermal cells, abundance of collenchyma, arrangement and number of vascular bundles, presence of sclerenchyma surrounding vascular bundles, number of tannin cells. The diagnostically useful anatomical features of stem to discriminate both taxa of Plumbago are degree of elevation of stem ridges, occurrence of double layered epidermis, size of epidermal cells, distinctness of endodermis, abundance and distribution of pericyclicsclerenchyama, number of vascular bundles. Anatomical features of taxonomic significance in root are width of cortex and abundance of starch grains in cortex cells, abundance and distribution of pericyclics clerenchyama, amount of vascularization, distribution, diameter and density of vessels, width of medullary ray.

Extract of a letter from John Huxham, M.D. F. R. S. to W. Watson, M.D. F. R. S. dated at Plymouth, the 10th of May, 1763. I have herewith sent you two extraordinary cases, which Mr. Francis Geach, one of our surgeons, put into my hands some time ago. I think there are some things remarkable in them. I have sent also three of the concretions found in the gall-bladder of the icteric person. The three others I reserve for making some experiments on them. They are all nearly of the same shape and size.

Anatomic studies have been performed on the leaf blade, petiole and annual shoot on six apple cultivars by means of scanning electron as well as light microscope. Four of the cultivars examined are resistant to scab (Florina, Freedom, MR-10, MR-11), whereas two of them are susceptible (Jonathan and Idared). Preliminary results suggest that differences in the width of cross sections of leaf blades, in hairyness, in the shape and size of epidermal cells, moreover, in the cross sections of petioles and shoots are considerable. Some of the anatomical properties seem to be correlated with scab resistance or susceptility of the respective cultivars. Therefore, further studies extending to other cultivars may corroborate our claims to find causal relations between anatomical traits of the leaves and disease, especially scab resistance of apple cultivars.

Shape And Size

The pore spaces in sandstones are the result of the original depositional fabric and the degree of post-depositional alteration that the rock has experienced. The largest pore volumes are present in coarse-grained, well-sorted materials with high sphericity. The chief mechanisms which alter the shape and size of the pores are precipitation of cementing agents and the dissolution of soluble components. Each process may operate alone or in combination with the other, or there may be several generations of cementation and solution.The scanning electron microscope has ‘been used in this study to reveal the morphology of the pore spaces in a variety of moderate porosity, orthoquartzites.

Chronische Entzündungen

Ein 58jähriger Mann wurde mit Übelkeit, Oberbauchschmerzen, einem palpablen Tumor im rechten oberen Epigastrium und begleitendem Fieber aber fehlender Leukozytose und CRP-Erhöhung aufgenommen. Sowohl die Ultraschalluntersuchung als auch eine im Anschluss durchgeführte Computertomographie deuteten auf einen malignen Tumor der Gallenblase mit Infiltration der Leber und begleitender Abszessformation in den Segmenten 4b und 3 hin. Die Indikation zur Entfernung des Tumors im Sinne einer Hemihepatektomie links mit Cholezystektomie und Abszessdrainage wurde gestellt. Intraoperativ fand sich dann jedoch eine chronisch-eitrige Cholezystitis ohne Beteiligung der Leber selbst, sodass nur eine Cholezystektomie durchgeführt werden musste. Die histologische Untersuchung der Gallenblase erbrachte keinen Hinweis auf ein malignes Geschehen. Der Patient erholte sich gut von dem operativen Eingriff und konnte sieben Tage später entlassen werden. Diese Fallbeschreibung zeigt die Probleme auf, die bei der Differentialdiagnostik von entzündlichen und malignen Gallenblasenerkrankungen mit Beteiligung von angrenzenden Strukturen, insbesondere der Leber, bestehen. Trotz apparativer Untersuchungen wie Sonographie und Computertomogramm ist die letztendlich richtige Diagnose häufig nur intraoperativ zu stellen und erst dann die adäquate Therapie festlegbar. Chronische Entzündungen der Gallenblase können als solide Tumoren imponieren und dann als maligne Prozesse der Gallenblase und der angrenzenden Lebersegmente fehlinterpretiert werden.
