Material and Methods: This study retrospectively evaluated 14 patients who had been operated on for acute abdo- men and had been diagnosed with Meckel’s diverticulitis (MD) in Ege University Medical Faculty Department of General Surgery, between October 2007 and October 2012. Results: Fourteen patients with a diagnosis of Meckel’s diverticulitis (MD) were retrospectively analyzed. Radiologi- cally, the abdominal computer tomography showed pathologies compatible with mechanical intestinal obstruction, Meckel’s diverticulitis and peridiverticular abscess, as well as detection of free air within the abdomen on direct abdominal X-ray. Among patients diagnosed with complicated Meckel’s diverticuli (obstruction, diverticulitis, perfo- ration) 10 patients had partial small bowel resection and end-to-end anastomosis (71.5%), three patients underwent diverticulum excision (21.4%), and one patient underwent right hemicolectomy+ileotransversostomy (7.1%). Conclusion: Meckel’s diverticulum is a vestigial remnant of an omphalomesenteric channel in the small bowel. It is a real congenital diverticular abnormality that contains all three layers of the small bowel. Surgical excision should be performed if Meckel’s diverticulum is detected in order to avoid incidental complications such as ulcer- ation, bleeding, bowel obstruction, diverticulitis or perforation.

Joseph-Hippolyte Cloquet (1787–1840) was an anatomist who, in 1815, defended a singular doctoral thesis—On odours, the sense of olfaction and the olfactory organs—then went on to publish, in 1821, the first complete treatise on rhinology. In our biographical sketch, we focus on Cloquet’s significant contributions to olfactory anatomy and physiology. His realization that odours are chemical and molecular in nature led him to formulate an accurate functional theory of the olfactory mucosa. Following a historical introduction, we review contemporary literature on the anatomical–functional understanding of olfaction and propose a (possibly deba- table) theory for the lexical deficits one encounters when trying to describe the sense of smell.

  • Johann Friedrich Meckel, the Younger (1781-1833) [1]
    Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) Johann Friedrich Meckel, the Younger (1781-1833) [1] By: O'Connell, Lindsey Keywords: Meckel's diverticulum [2] recapitulation [3] recapitulation theory [4] Meckel-Serres law [5] Johann Friedrich Meckel [6] studied abnormal animal and human anatomy in nineteenth century Germany in an attempt to explain embryological development. During Meckel’s lifetime he catalogued embryonic malformations in multiple treatises. Meckel’s focus on malformations led him to develop concepts like primary and secondary malformations, atavism, and recapitulation– all of which influenced the fields of medicine and embryology [7] during the nineteenth and twentieth centuries. Meckel was born 13 October 1781, in the university town of Halle, Germany. His father, Phillip Friedrich Theodor Meckel, and his grandfatherJ, ohann Friedrich Meckel [6] the elder, were physicians and anatomists and Meckel grew up helping his father prepare new specimens for the anatomical museum in their house. Meckel attended a local elementary school until the age of fourteen, when he traveled to Magdeburg, Germany to study at the Cathedral Gymnasium, a university preparatory school. From 1798 to 1801 Meckel attended the University of Halle [8], in Halle, Germany, where he studied medicine and anatomy. During those years at Halle, Meckel’s professors included Kurt Sprengel, Johann C. Reil, and his father. Reil was Meckel’s mentor and encouraged him to study brain anatomy. In the final year of his doctoral degree studies, Meckel transferred to the University of Göttingen, in Göttingen, Germany, where he worked on comparative anatomy with Johann Friedrich Blumenbach. After a year at Göttingen, Meckel returned to Halle and presented his thesis on cardiac abnormalities, “De Cordis Conditionibus Abnormibus” (Abnormal Conditions of the Heart), after which he received his doctorate in 1802.

Dans ces monstres, ils aperçurent la main de Dieu. En 1573 déjà, Ambroise Paré imputa leur origine au Tout-Puissant, au courroux de Dieu, à l’ima - gination maternelle, au bassin trop petit ou trop étroit, au mode de vie des femmes, à une force mécanique agissant brusquement de l’extérieur, à l’hérédité, aux maladies acciden - telles, à une quantité trop faible ou trop abondante de la semence (à l’avis d’Ambroise Paré), à une qualité inférieure de cette substance, au mélange de la semence de diverses provenances et finalement à l’influence du diable (1). Les points de vue de Jacques Auguste Blondel En 1727, Jacques Auguste Blondel (né à Paris, en 1666, mais pratiquant la médecine à Londres), publia un mémoire anonyme sur l’imagination maternelle, intitulé The Strength of Imagination in Pregnant Women Examined and the opinion that marks and deformities in children arise from thence, demonstrated to be a vulgar error (2). Blondel rejeta carrément l’effet de l’imagination maternelle sur le fœtus qui se développe dans l’utérus. Par contre, la grande majorité des médecins adhérèrent à cette théorie. Peu de temps après, Daniel Turner, chirurgien à Londres, qui, en 1714, publia le mémoire, inti - tulé Spots and Marks of a diverse Resemblance imprest on the skin of the Fœtus, by the Force of the Mother’s Fancy , déclara la guerre au docteur Blondel (3).

  • The Meckel-Serres Conception of Recapitulation [1]
    Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) The Meckel-Serres Conception of Recapitulation [1] By: O'Connell, Lindsey Keywords: recapitulation [2] Laws of Development [3] Meckel-Serres law [4] Johann Friedrich Meckel [5] and Antoine Etienne Reynaud Augustin Serres developed in the early 1800s the basic principles of what later became called the Meckel-Serres Law [6]. Meckel and Serres both argued that fetal deformities result when development prematurely stops, and they argued that these arrests characterized lower life forms, through which higher order organisms progress during normal development. The concept that the embryos of higher order organisms progress through successive stages in which they resemble lower level forms is called recapitulation. Meckel, a professor of anatomy at the University of Halle [7] in Halle, Germany, and Serres, a physician at Hôtel-Dieu de Paris in Paris, France, did not work together. Rather, in the late nineteenth and early twentieth centuries, their similar approaches, in which they compared the anatomy and embryos of different species so as to relate stages of embryonic development to the scala naturae, led other scientists to generalize their individual concepts into one general theory. The recapitulation ideas of Meckel and Serres became part of the mid-eighteenth century debate about how to explain morphological similarities between species. The concept of scala naturae, or the great chain of being, had an early proponent in Aristotle [8], who worked in Greece four centuries before the common era. Aristotle’s scala naturae arranged all organisms into a hierarchy based on the complexity of their form.

  • The Foundations of Archetype Theory in Evolutionary Biology: Kant, Goethe, and Carus Robert J
    The Foundations of Archetype Theory in Evolutionary Biology: Kant, Goethe, and Carus Robert J. Richards University of Chicago harles darwin (1809–82) was not only a creative thinker but also a creative rethinker. Darwin perceived connections among well-established concepts in biology and reconstructed them into a coherent theory of the evolution of organisms. Even Cthe principle of natural selection had its foundation in earlier ideas, especially those concerning domestic breeding; and, of course, Thomas Malthus (1766–1834) suggested a way of conceiving how population pressure under environmental constraints might perform a function similar to that of the breeder’s “picking.” Even before he formulated the principle of natural selection, how- ever, Darwin was convinced of the transmutation of species. That conviction had its proximate origins in the jolt he received in the spring of 1837 when he began sorting the specimens he had collected during his Beagle voyage (1831–36). John Gould (1804–81), the chief ornithologist at the British Museum, explained to the young naturalist that the Galapagos mocking birds, which Darwin had assumed to be varieties of a single species, were actually good, independent species. 1 That correction tripped a mind at the ready. Darwin, of course, was aware of the evolution- ary proposals of his grandfather Erasmus Darwin (1731–1802) and of John Baptiste de Lamarck (1744–1829). But two ideas in particular seem to have prepared him for drawing the transmutation inference: the idea of the morphological unity of type and that of embryological recapitulation. Without these two notions warming the possibility, Gould’s correction would not likely have struck Darwin as it did.

  • The Problem of Vertebrate Ancestry, 1859-1875
    AN ABSTRACT OF THE THESIS OF Roberta Jane Beeson for the degree of Doctor of Philosophy in General Science (Biological Science) presented on May 8, 1978 Title: BRIDGING THE GAP: THE PROBLEM OF VERTEBRATE ANCESTRY, 1859-1875 Abstract approved: Redacted for Privacy Paul Lawrence Farber Determination of the Vertebrate pedigree wasa particularly enigmatic problem for evolutionary morpholo- gists of the early post-Darwinian period. At that time, practically no characteristics were known by which the Vertebrates could be linked to any of the other animal groups. Up to the 1850's, most research in embryology and anatomy had reinforced the idea that wide differences existed in the basic structural and developmental patterns of Vertebrates and animals belonging to other branches of the animal kingdom. As a result, morphological practice was affected by a strong tradition against comparison of Vertebrates and Invertebrates. With the acceptance of the evolutionary viewpoint, it became theoretically valid to compare animals of different types, based on the possi- bility of their remote common ancestry. However, the practical matter of demonstrating that relationship with concrete evidence proved to be one of the most difficult challenges confronting early evolutionary morphology. Three different theories were proposed between 1864 and 1870, each attempting to link the Vertebratesand one of the Invertebrate groups to a hypotheticalcommon ancestor. In 1864, Franz Leydig proposed an evolutionary relationship between Arthropods and Vertebrates; in1866, Ernst Haeckel attempted to connect Vertebrates with Roundworms; and in 1868, on the basis ofnew research by Aleksandr Kovalevskii, Haeckel proposed another theory which linked Vertebrates with Tunicates. The proposals which formed the basis of the Tunicate theory becamethe center of a heated debate in the late 1860's and early 1870's.
