• Article: [Craniogenesis in the laughing gull (Larus ridibundus L.). The reconstruction of the basic plan of the bird].

  E Weber
  [show abstract] [hide abstract]
  ABSTRACT: To contribute to the knowledge of the cranium of older bird embryos, the chondrocranium and osteocranium of the Black-headed Gull (Larus ridibundus) are described. The chondrocranium of the Black-headed Gull is compared with the chondrocranium of other bird species with special consideration of functional and phylogenetic aspects. As a result a "grundplan" of the bird chondrocranium is reconstructed. Most of the chondrocranial autapomorphies of birds are connected with the enlargement of the eyes, the development of a beak and a prokinetic skull, and the reduction of the olfactory system.

• Article: [Kinematics and dynamics of the temporomandibular joint and of the movements of the mandible].

  F K Fuss
  [show abstract] [hide abstract]
  ABSTRACT: In order to analyze the complicated movements of the mandible as the open-closing movement and the protrusio are, it is useful to evaluate the basic kinematic principles and reduce them to simple technical constructions. Both the open-closing movement and the protrusio could be reduced to 4-bar links, which were used to simulate the movements with help of a computer. Besides, the polodes and the curves of points in the muscular attachments could be constructed. The 2 entirely different 4-bar links have 3 things in common: The resting system - cranium, the moving system - mandibula, and 1 of the 2 arms connecting these 2 systems - the ligamentum laterale. As this ligament is taut during movements it can be considered a "guiding ligament" representing 1 of the 3 determining components of the mandibular movements. The other of the 2 arms has no anatomical equivalent; this arm, however, is "replaced" by the 2 other determining components of the mandibular movements: the joint and the muscles. The curves, which the Caput mandibulae describes, are practically identical for the open-closing movement and the protrusio despite of the different 4-bar links and these curves exactly correspond to the Discus articularis, taut by the upper part of the M. pterygoideus lateralis. The muscles do not only just move the mandibula, but they are also the component, which can choose between the different mandibular movements. By means of the curves, which points in the muscular attachments describe, the function of the masticatory muscles could be analyzed exactly.

• Article: [The relationship between the gait of humans and the hip joint structure in the frontal plane].

  S Blumentritt
  [show abstract] [hide abstract]
  ABSTRACT: The forces at the hip joint acting between the femur head and acetabulum are significant for the function properties a lifetime. These forces are determined by the geometry of skeleton and the dynamic of limbs motions. The interaction of hip joint anatomy, gait dynamics, and joint force is described biomechanically. The connections are verified by 35 adults. The results of this investigation allow to conclude that individual variants of macroscopic hip joint anatomy are founded by the relation between maximum loading during gait and hip joint structure. The correlation between the angle of weight-bearing-surface and the hip joint force direction is very significant. For a normal hip joint function, the anatomical structure of the acetabulum is essential more important as that of the coxal femur.

• Article: [The ontogenesis of the manubrium sterni in Tupaia belangeri].

  S Eickhoff
  [show abstract] [hide abstract]
  ABSTRACT: The morphogenesis of the manubrium sterni was studied in a series of dated embryos of Tupaia belangeri. In addition to the sternal bands, the "paired suprasternal Anlage" takes part in the shaping of the manubrium sterni as reported by Klima (1968) for other mammals. It forms skeletal elements that mediate between the clavicle and the manubrium: the sternocalvicular ligament and the paired prominence on the dorsal surface of the manubrium, which underlies the clavicles. The paired prominence corresponds to the praeclavium present in some therians. Very probably, the discus articularis of the sternoclavicular articulation of some primates can be attributed to the suprasternal Anlage. There was, however, no indication that the ossa suprasternalia of primates develop from the suprasternal Anlagen: In Tupaia these Anlagen do not form the cranial part of the manubrium. Klima's "unpaired Anlage" develops differently in Tupaia than in other therians. It consists of connective tissue and is not integrated into the manubrium. It presents an insertion surface for the M. pectoralis major, which shifts its origin onto the manubrium, after the sternal bands have fused. The homology of the "unpaired Anlage" and the "pars chondralis interclaviculae" is doubtful.

• Article: [Preliminary study of an interdisciplinary examination of the body height proportions of Germans in the 19th century and of the influence of living conditions. I.

  ABSTRACT: Researches about the influences of the nutritional conditions on body-height need interdisciplinary co-operation of Anthropology, History, and Dietetics. Such a team will be difficult succeed in joining. Especially interesting for human sciences are nutritional-constitutional researches on German populations in the 19th century, because in this century multifarious varieties exist within the German settlement. Author hopes, that preliminary original researches and first trends in results facilitate the joining of such an interdisciplinary team. In part I of this inquiry, the necessity for nutritional-constitutional researches are justified, problems are treated and mustering-statistics, the most important data-material, are collected for the political regions of that time from North to the kingdom Württemberg. The kingdom Württemberg of course is the political region with the most continuous data-series, but the data-material is poor on body-height-means and needs new statistical treatments. Less data are particularly available from the middle of the German settlement.

• Article: [Preliminary studies of an interdisciplinary inquiry of the body height proportions of Germans in the 19th century and of the influence of living conditions. II.

  ABSTRACT: In Part I of this examinations, preliminary original researches about the constitutional situations in Germany from the North to the kingdom Württemberg has been presented. In this part II, such preliminary researches follow for the other southern part of the German settlement. With references to Baden, Alsace-Lorraine, and Bavaria first since the second part of the 19th century, comprehensive anthropological data exist, but these contain valuable and differentiated data material. A first analysis for this German data material does not reveal regular relation-ships between body-height, urban and rural life, and geographical altitude. But there are relation-ships between wealthy and poor social classes and between educated and heavily working people, and there exists a negative trend in the body-height-means from the North and South to the middle of the German settlement with minima in Saxony and in several regions in Southern Germany. As spread for the different means about 160 to more than 170 cm is to estimate. The spread seems to be broader in the second half of the 19th century, presumably because the better life-conditions does not hold for all Germans in the same manner. About of the beginning of the 20th century, the body-height-means show an increase with may by interpreted as an kind of rehabilitation after times of emergency in the early industrialization and of difficulties in food supply.

• Article: Localization of intermediate filament proteins in various structures of the human placenta as revealed by immunoperoxidase technique.

  J Mirecka, M Hanarz
  [show abstract] [hide abstract]
  ABSTRACT: Formalin-fixed, paraffin embedded fragments of normal human placenta were subjected to immunoperoxidase technique with the use of Dako Kits appropriate for detection of vimentin, desmin, and cytokeratins (K 660, 530, and 518 respectively). Distribution of the intermediate filament proteins in syncytiotrophoblast, connective tissue of villous stroma, walls of blood vessels as well as in cells of basal plate and placental islets was compared. General pattern of staining and its localization was characteristic for each of the 3 types of antibodies. In spite of that, most structures observed revealed the presence of more than one type of intermediate filament proteins, with the exception of syncytiotrophoblast containing cytokeratins only. Staining of blood serum and of connective tissue matrix with anti-desmin and anti-cytokeratin antibodies was also observed, whereas fibrinoid remained always negative.

  [show abstract] [hide abstract]
  ABSTRACT: To avoid neuralgic pain as consequence of damaging the nasodental nerve during surgical treatment of chronic maxillary sinusitis by the Caldwell-Luc-approach, the accurate knowledge of the nasodental nerve's course might be useful for the surgeon. Therefore, the anatomy of this nerve was evaluated by dissection of 23 human specimens. The nasodental nerve is the largest single branch of the infraorbital nerve's Rr. alveolares superiores anteriores. The first course of the nasodental nerve in the roof of the maxillary sinus has a (mean) length of 14 mm on the right and 16 mm on the left side. Mostly it accompanies the infraorbital nerve in the canalis infraorbitalis and leaves this common channel 4 mm on the right and 6 mm on the left behind the infraorbital foramen. The next part of the nerve, which is orientated from laterocranial to mediocaudal, is found in the front wall of the antrum Highmori and has a length of 18 mm at the right and 20 mm at the left. Next it leaves the sinus through a tiny channel at the angle between the front and the medial wall of the maxillary sinus. On the last course, the nerve runs in the lateral wall of the nose 8 mm at the right and 9 mm at the left behind the rim of the apertura piriformis.

• Article: On the fine structure of the parotid gland of tufted capuchin monkey, Cebus apella.

  [show abstract] [hide abstract]
  ABSTRACT: The parotid gland of the tufted capuchin monkey (Cebus apella) was examined by scanning and transmission electron microscopy. In general the ultrastructural morphology of this gland appears similar to that described in spider and squirrel monkeys. This study has established that the gland is serous. Acinar cells, which contain a well developed granular endoplasmic reticulum and a prominent GOLGI complex, produce a single secretory material. Myoepithelial cells are present around acini and around intercalated ducts. The intercalated ducts, which are composed of cells that show no evidence of secretory activity, lead into striated ducts.

• Article: Modifying effects of calcium on aluminum induced toxicity in mammalian tissues in vivo.

  A K Roy, G Talukder, A Sharma
  [show abstract] [hide abstract]
  ABSTRACT: Oral administration of calcium, following by aluminium or together with Al, has been found to counteract the toxic effects of the latter metal as observed in histological preparations of liver, brain, kidney, and bone of laboratory albino rats. No such improvement was seen if Ca was administered after Al. The protection afforded by Ca against Al toxicity may be due to the previous occupation by Ca ions of the binding sites of Al ions in the affected organs.

  [show abstract] [hide abstract]
  ABSTRACT: Ultrastructural changes of endothelial cells of the mesenteric microcirculatory bed were morphometrically and statistically examined on a total of 32 male R-rats 15, 30, 60, and 120 min after a traumatic-haemorrhagic shock (THS). Significant changes of various parameters were observed at all times after shock compared with a control group (8 animals). The findings can be divided into 2 main forms of reaction, namely activation and injury. At all times overlapping occurred and endothelial cells were considerably heteromorphic. Severe, possible irreversible injuries were rare.

• Article: Fine structure of the boundary tissue of the seminiferous tubuli of the vampire bat (Desmodus rotundus, G.; Microchiroptera).

  A M Orsi, C A Vicentini, S M Dias, M H Moreno
  [show abstract] [hide abstract]
  ABSTRACT: Structurally the boundary tissue of the vampire bat seminiferous tubuli showed 2 to 5 layers of connective tissue in which elongated contractile cells and lamellar and/or fibrillar collagen were noticed. This boundary tissue forms the seminiferous tubular lamina propria. Its structure was more complex around the seminiferous tubuli near the Capsula testicularis than between the adjacent and contiguous tubuli into the testicular lobuli. The whole ultrastructural organization of the seminiferous lamina propria was described here.

  ABSTRACT: Although Cave (1987) accepts the theory that the Meckelian ossicles originate from the maxilloturbinals, evidence given in his study in fact supports the opinion of Klima and van Bree (1985) that the Meckelian ossicles arise from elements of the nasal floor, solum nasi, of the embryonic nasal capsule, in particular from the lamina transversalis anterior and the cartilago paraseptalis.
