Origin and distribution of facial nerve anatomy in van cats     

İsmail Hakkı Nur  William Pérez  Horst Erich König 《Anatomia, histologia, embryologia》2021,50(3):658-667

This study aims to reveal the morphological properties of facial nerve and the middle ear in Van cats. Study material was composed of 6 female Van cats. Dissections were performed under a Zoom Stereo Microscope. There was no plexus buccalis in Van cats. The chorda tympani was observed to pass through an opening in the tympanic cavity, emerge through a small opening just behind the retroarticular process, and join the lingual nerve. A rounded anatomical formation with a size of 2.75 ± 0.3 mm was found to be located within the mastoid process of the temporal bone between the facial nerve and the auricular branch of the vagus nerve. The stapes nerve was not present. The geniculate ganglion was very prominent and about 1.00 mm high. The deep petrosal nerve was observed to emerge from the plexus tympanicus. The bulla tympanica was 18.96 ± 0.10 mm long, 13.03 ± 0.20 mm wide and 13.16 ± 0.20 mm high. After leaving the mandibular nerve, the n.tensoris tympani coursed caudally around the a.maxillaris, formed an ansa, entered the tympanic cavity through the canalis musculotubarius and reached an end in the m. tensor tympani. Due to the scarcity of studies on the middle ears of Van cats, it is thought that this study will fill a gap in the field of veterinary anatomy.  相似文献

Fluorine-containing intermediates for pesticides     

Rudolf P. J. Braden  Erich Klauke 《Pest management science》1986,17(4):418-429

Compounds containing fluoro- or fluoroalkyl-substituents often show interesting biological activities. However, the high cost of introducing fluorine into a molecule may make the manufacture of a compound with excellent biological activity too expensive for commercial viability. The cheapest source of fluorine is hydrogen fluoride but most fluorine substitution reactions described in the literature make use of alkali metal fluorides which, although more convenient to handle in the laboratory, are much more expensive. This paper describes the use of hydrogen fluoride in new synthetic routes to a number of intermediates for the manufacture of commercially useful pesticides. These include compounds containing the dichlorofluoromethylsulphenyl radical, derivatives of perfluoro-2,5-diazahexa-2,4-diene, various aromatic fluoro compounds and some fluorinated benzodioxoles and benzodioxenes.  相似文献   

N-(pyrid-3-yl)thioureas and derivatives as acaricides. II. Quantitative structure-activity relationships and chemodynamic behaviour     

Alfons Pascual  Alfred Rindlisbacher  Heinz Schmidli  Erich Stamm 《Pest management science》1995,44(4):369-379

The biological activity of a series of N-(pyrid-3-yl)thioureas and -carbodiimides, analogues of the insecticide/acaricide diafenthiuron, towards the carmine spider mite (Tetranychus cinnabarinus Boisd.) and the two-spotted spider mite (T. urticae Koch) was analysed using QSAR methodology. A canonical correlation analysis allowed for the establishment of a prediction model and the identification of outliers within that model. The chemodynamic behaviour of certain compounds in the two series, including these outliers, determined by using photochemical experiments in the laboratory as well as in the glasshouse, was shown to be responsible for anomalous results obtained in the biological tests. It was found from the above study that the biological activity towards both spider mite species is extremely sensitive to the kinetics of formation of the carbodiimides from the corresponding thioureas and to the photostability of the former. The results obtained with a thiourea which underwent no appreciable photochemical transformation into the corresponding carbodiimide supported the hypothesis that the thioureas are also in-vivo propesticides of the acaricidal carbodiimides.  相似文献   

Compendium of the history of veterinary anatomy of Rumania: for the 100th birthday of one of their most famous anatomists,Vasile Ghetie     

König HE 《Historia medicinae veterinariae》2003,28(2):54-63

The lessons of veterinary anatomy, firstly it was called "Zootomie", began in Rumania in 1853 and took place at educational establishments for ambulances and at schools for human medicine. The first veterinary school of the country was opened at the 16th of May 1861. The academically trained anatomy began with Prof. Constantin Gavrilescu. The most famous representative of anatomy was Prof. Vasile Ghetie (1903-1990). His act of life positions him beside the great anatomists of the gone century Schmaltz, Barone and Grau.  相似文献   

Natural bovine lentivirus type 1 infection in Holstein dairy cattle. II. Lymphoid tissue lesions     

Snider TG  Coats KS  Storts RW  Graves KF  Cooper CR  Hoyt PG  Luther DG  Jenny BF 《Comparative immunology, microbiology and infectious diseases》2003,26(1):1-15

Bovine immunodeficiency virus (BIV) in Holstein cows was associated with morphologic evidence of lymphoid organ deficiency. Cows were subjected to normal management practices including parturition and lactation without adverse environmental stresses. During the clinical disease process there was marked weight loss and wasting with frequent and severe concurrent infections. Lymphoid follicular hyperplasia and dysplasia in lymph nodes, and hypertrophy and hyperplasia in hemal lymph nodes were characteristics of the lymphoid tissues. Atrophy of lymphoid cell compartments with depletion of lymphocytes and a lymphocytic lymphoid folliculitis were components of the lymphoid system pathology. The nodal tissue lesions resembled those observed in feline, simian, and human lentiviral disease. A functional correlation with immune system deficiency was the development of multiple bacterial infections which failed to resolve after appropriate therapy. The BIV-associated disease syndrome in dairy cows may be useful as a model system for investigation of the pathogenesis of the lymphoid organ changes that occur in humans and animals with lentiviral infection.  相似文献

Lignin chemistry—past,present and future     

Erich Adler 《Wood Science and Technology》1977,11(3):169-218

Summary Some pertinent results and views from the earlier history of lignin chemistry, pointing to the importance of the arylpropane skeleton, are outlined. Later development, beginning with the dehydrogenation theory and experimental studies on the dehydrogenative polymerization of p-hydroxycinnamyl alcohols, is then reviewed. Finally, recent degradative work resulting in a detailed picture of lignin structure is discussed.  相似文献
