VARIANT POSITION OF THE GALLBLADDER ASSOCIATED WITH ABNORMAL PERITONEAL FOLD AROUND IT. Variantes en la posición de la vesícula biliar asociada con un pliegue peritoneal anormal a su alrededor
Revista Argentina de Anatomía Clínica, 2016Co-Authors: Narendra Pamidi, Srinivasa Rao Sirasanagandla, Satheesha Nayak B, Raghu JettiAbstract:Los pliegues peritoneales anomalos alrededor de la vesicula biliar son muy raros y pocos fueron reportados en el pasado. La presencia de tales pliegues peritoneales son probablemente debidos a la extension del mesenterio Ventral que forma el omento menor. En el caso presente, reportamos un pliegue peritoneal anomalo suspendiendo la vesicula biliar desde la superficie inferior del higado, a lo largo de la margen izquierda de la fosa para la vesicula biliar. Este pliegue, cuando se trazo cuidadosamente, se continuaba con el colon transverso, mesocolon transverso y tambien se encontro fusionado con la segunda porcion del duodeno. La vesicula biliar con inusuales pliegues peritoneales tiene tendencia a volvulo, una rara enfermedad que exige la intervencion quirurgica inmediata. El conocimiento de la posibilidad de tal anomalia peritoneal alrededor de la vesicula biliar facilita la interpretacion de los hallazgos de la imagen para el diagnostico apropiado. Anomalous peritoneal folds around the gallbladder are very rare and a few were reported in the past. The presence of such peritoneal folds is probably due to extension of the Ventral Mesentery which forms the lesser omentum. In the present case we report anomalous peritoneal fold suspending the gall bladder from the undersurface of the liver, along the left margin of the fossa for gallbladder. This fold, when traced carefully, became continuous with transverse colon, transverse mesocolon and also found to be merged with the second part of duodenum. The gallbladder with unusual peritoneal folds has a tendency to volvulus, a rare surgical disease which demands the immediate surgical intervention. Awareness of the possibility of such peritoneal anomaly around gallbladder facilitates the interpretation of image findings for proper diagnosis.

Lungs and mesopneumonia of scincomorph lizards (Reptilia: Squamata)
Organisms Diversity & Evolution, 2005Co-Authors: Wilfried Klein, Christian Reuter, Wolfgang Böhme, Steven F. PerryAbstract:Abstract Mesopneumonia of 28 and lungs of 44 species of scincomorph lizards are described, representing mesopneumonia in six of the seven scincomorph families and lungs of all seven families of this taxon. Except for gymnophthalmids and scincids, a family typical organization of mesopneumonia occurs. In cordylids, gerrhosaurids, xantusiids and lacertids the complete right Ventral mesopneumonium (VMp) inserts cranially on the posterior vena cava and caudally on the dorsal surface of the right liver lobe. The left VMp is attached to the ventrolateral body wall in cordylids and lacertids; in gerrhosaurids the left VMp is short and inserts on the pericardium and the posterior vena cava; in xantusiids the left VMp is reduced and the lungs are fused cranially with the pericardium. In scincids the VMp of both sides vary in length and insert on the Ventral Mesentery, or may be lacking completely. The visceral topology of the gymnophthalmids Calyptommatus and Notobachia differs from the general scincomorph pattern, with the liver and stomach elongated and situated on the right and left side of the body cavity, respectively. The left and the right VMp extend over the entire length of the lungs and insert on the Ventral Mesentery. All lungs examined in the study are single-chambered and show no major structural variability of the inner surfaces, except in lacertids, some gerrhosaurids, Cordylus , and two genera of gymnophthalmids ( Echinosaura and Neusticurus ). In these groups, rows of dorsomedial niches are present. See also Electronic Supplement at: http://www.senckenberg.de/odes/05-06.htm

The mesopneumonia and the post-hepatic septum of the Teiioidea (Reptilia: Squamata)
Acta Zoologica, 2000Co-Authors: Wilfried Klein, Wolfgang Böhme, Steven F. PerryAbstract:Klein, W., Bohme, W. and Perry, S. F. 2000. The mesopneumonia and the post-hepatic septum of the Teiioidea (Reptilia: Squamata). —Acta Zoologica (Stockholm) 81: 109–119 This study investigates the structure of the pleuroperitoneal cavity of Teiioidea. Seven of nine genera of Teiidae and eight of 35 genera of Gymnophthalmidae were dissected and the results are presented in a highly schematic two-dimensional representation. The main anatomical differences between the two families are (1) the presence of a hepatic ligament which fuses with the pericardiaco-peritoneal septum in the Gymnophthalmidae but not in the Teiidae; (2) the presence of a Ventral mesopneumonium on the right side in the Gymnophthalmidae, while this structure is secondarily lacking in the Teiidae; (3) that the post-hepatic septum of Teiidae consists of a bipartite hepatic ligament and the Ventral Mesentery, while in gymnophthalmids the hepatic ligament remains undivided. Neusticurus and Echinosaura completely lack a post-hepatic septum. The results are consistent with the hypothesis that the Gymnophthalmidae are primitive within the Teiioidea and that the Tupinambinae are the most highly derived teiids. We propose that the post-hepatic septum may restrict passive visceral movement during breathing, thereby increasing the efficiency of respiratory effort; a modification that could benefit the fitness of active, predatory teiids.
