  • Female reproductive system morphology of crab-eating fox (Cerdocyon thous)
           and cryopreservation of genetic material for animal germplasm bank
    • Authors: L. C. Machado; K. C. S. Roballo, F. S. Cury, C. E. Ambrósio
      Abstract: The sprawl of the urbanization and road network process without building ecological corridors contributes to the high mortality rates and a threat to the population decline of wild species such as the crab-eating fox. A strategy for the ex situ conservation is the study of the reproductive biology of the species and cryopreservation of their genetic heritage through the formation of an animal germplasm bank. This research is in accordance with the principles adopted by Brazilian College of Animal Experimentation. Reproductive systems of Cerdocyon thous females (n = 7) were examined macroscopically and microscopically by histological techniques and scanning electron microscopy. Gross features showed the shape of the ovaries was similar to a bean, and the elongated oviducts lengths were between 5 and 8 cm, with body of the uterus (3 cm) with long and narrow uterine horns (9–11 cm). The cervix was as a single annular conformation carrying out communication between the uterus and the vagina. The vagina has lengthened and circular muscle and the vulva with dense anatomical conformation with a quite pronounced clitoris. In addition, with regard to the establishment of a cell line (fibroblasts) for the gene bank enrichment, cells showed a low clonogenic capacity, especially when compared to domestic dogs, which can be explained by “in vitro” environment, age and diet of the animal. However, it was possible to create a bank of limited cell number. This study had morphological and preservationist character and aimed to help at long term in the conservation of wild animal's genetic resources.

  • The location of projection neurons to the biceps brachii muscle in the
           telencephalon of the pigeon
    • Authors: J. H. Park; J. H. Ahn, S. Y. Choi, J. H. Cho, T.-K. Lee, I. H. Kim, J.-C. Lee, J. H. Choi, I. K. Hwang, Y. J. Lee, E. Lee, S. Park, J. Lim, K. Seo, M.-H. Won
      Abstract: Few studies regarding the anatomical distribution of motor neurons innervating muscles of the arm have been demonstrated in avian brains. The purpose of this study was to finely determine the localization of cerebral neurons innervating the biceps brachii muscle in the pigeon. The cholera toxin B subunit (CTB) was employed as a retrograde tracer to determine the location of neurons controlling the biceps brachii muscle in the telencephalon following intramuscular injection in male pigeons (n = 7), which were killed 14 days after intramuscular injection with CTB. We found that CTB-labelled neurons were located contralaterally in the hyperpallium apicale of the rostral telencephalon and that most of the CTB-labelled neurons were pyramidal in shape. This study shows that CTB is easily taken up by nerve terminals which innervate the biceps brachii muscle of the pigeon and that cerebral motor neurons controlling the biceps brachii muscle are located in the hyperpallium apicale.

  • Sexual dimorphism in jaw muscles of the Japanese sparrowhawk (Accipiter
    • Authors: H. Wang; J. Yan, Z. Zhang
      Abstract: Materials suitable for anatomical research of raptorial birds are rare. Bird-eating raptors show distinct inter-sexual differences in body size and parental roles. The large females catch larger prey and prepare small morsels to feed their young using their hooked beaks. Here, we investigated the architectural properties of different jaw muscles of the Japanese sparrowhawk (Accipiter gularis) and examined whether there is sexual dimorphism in their architectural design. The results showed that musculus depressor mandibulae, the opener of the lower jaw, was characterized by relatively long fascicle length, whereas musculus pterygoideus was characterized by its larger mass and physiological cross-sectional area (PCSA) in both sexes. Females have the potential capacity to produce rapid and strong bites by their significantly longer fascicle length of M. depressor mandibulae and larger mass and PCSA of M. pterygoideus. For body size-matched gender, jaw muscles of males had fibres of relatively longer length than females, enabling greater velocity and excursion. Architectural characteristics of jaw muscles, together with the absolute dimorphism (the fascicle length of M. depressor mandibulae, the muscle mass and PCSA of M. pterygoideus) and relative dimorphism in the muscle mass of M. pterygoideus, reflect dietary difference and asymmetric parental roles between the sexes.

  • Asymmetrical size and functionality of the pampas deer (Ozotoceros
           bezoarticus) testes: Right testis is bigger but left testis is more
           efficient in spermatogenesis
    • Authors: Rodolfo Ungerfeld; Matías Villagrán, Lorena Lacuesta, Noelia Vazquez, William Pérez
      Abstract: Information about gonadal asymmetries in ruminants is very scarce. In this work, we performed three complementary studies to compare characteristics of both testes: (i) weight and size of offspring and adult dead males; (ii) the tissue:fluid relationship determined by ultrasound scanning; and (iii) the spermatogenic status using fine needle aspiration cytology. The right testis was heavier than the left one in both offspring and adult animals and had greater width and volume in adult males than the left one. The ultrasound pixel intensity was similar in both testes. The right testis tended to have more spermatogonia (p = .06) and had a greater percentage of early spermatids (p = .004) than the left testis. On the other hand, the left testis had a greater percentage of spermatozoa (p = .05). The left testis had a greater spermatozoa/spermatogonia ratio (p = .02) and tended to have more spermatozoa/Sertoli cells ratio (p = .07). The spermatogenic index tended to be greater in the left than in the right testis (p = .06). Overall, we concluded that the right testis of pampas deer males is bigger but according to the cytology, it seems to be less spermatogenically effective than the left one, but these differences are not explained by different tissue:fluid ratio in each testis. Although differences were greater in adults than in offspring, asymmetry was observed even in just born offspring.

  • Identification of telocytes in the porcine heart
    • Authors: H. Tay; T. Vandecasteele, W. Van den Broeck
      Abstract: Recently, a new interstitial cell type called telocyte has been identified. Telocytes are found in many organs including the heart, where they are especially well described. However, their presence in the porcine heart has not yet been proven. The pig is a valuable animal model in research because of its resemblance with man, making it interesting to determine whether telocytes can be found in pigs as well. The focus of this study is the identification and ultrastructural description of telocytes in the heart tissue of pig. Using transmission electron microscopy, telocytes were found in both left and right atrium and ventricle, usually close to cardiomyocytes and/or blood vessels. Their most important characteristic is the long cytoplasmic processes called telopodes, which have a moniliform aspect, measure tens of μm and usually have a thickness below 0.2 μm. This unique morphological feature enables telocytes to be recognized from other interstitial cells such as fibroblasts. Additional observations include the ability to release extracellular vesicles and to make contacts with other structures such as endothelial cells, suggesting a role in intercellular communication.

  • Histological characterization of umbilical cord in alpaca (Vicugna pacos)
    • Authors: L. M. Barrios-Arpi; J.-L. Rodríguez Gutiérrez, B. Lopez-Torres
      Abstract: The histomorphometric features of umbilical cord constituents in seven foetuses of alpaca (Vicugna pacos) from Cerro de Pasco, Department, Peru, were determined. Sections of 2–5 cm of umbilical cord were fixed in 10% neutral buffered formalin and processed for light microscopy. Standard histological slides stained with haematoxylin and eosin, Masson's trichrome and Van Gieson's trichrome were obtained. Histologically, common features of umbilical artery and vein were observed as well as mucous connective tissue, some cell features that compound this tissue constituted by cells presented features of myofibroblasts. Among most important findings that were observed, the lumen of umbilical vein was obliterated into star-shaped form with the thinner umbilical artery wall; the smooth muscles and fibroblast were comparatively more in number in umbilical artery than that of umbilical vein, and the tunica media was larger in dimension than the tunica adventitia in umbilical vein. Conclusively, this histological study features an observation of the umbilical cord of alpaca foetuses and shows the similarity between them and those of other mammal species, including dromedaries and South American camelids.

  • TGF-β1 attenuated branching morphogenesis of embryonic murine
           submandibular gland through Smad3 activation
    • Authors: P. Gao; X.-H. Qiao, L.-M. Gou, Y. Huang, Q.-H. Li, L.-J. Li, X.-Y. Wang, C.-J. Li
      Abstract: Transforming growth factor-β1 (TGF-β1) plays several crucial regulatory roles in multiple physiological and pathological processes. The aim of this work was to investigate the role of TGF-β1 in branching morphogenesis of salivary gland. We harvested and cultured submandibular salivary glands (SMGs) from murine embryos, which were then treated with exogenous TGF-β1, or its neutralized antibody, Smad3 inhibitor, or Smad3 small interfering RNA (siRNA). Our results suggested that TGF-β1 attenuated branching morphogenesis of embryonic murine SMG via Smad3 activation, thus playing a negative regulatory role in salivary gland development.

  • Microtomographic Parameters and Nanoindentation of the Hoof of Girolando
    • Authors: B. M. Assis; L. A. F. Silva, C. R. O. Lima, F. J. F. Sant'Ana, G. P. Santos, V. A. S. Vulcani, R. E. Rabelo
      Abstract: The aim of this study was to describe the microstructure of the pigmented and depigmented hoof capsule of Girolando cattle by bi- and tridimensional microtomography and nanoindentation, analysing the possible relation between these findings and the susceptibility of such animals to podal diseases. To carry out the microtomography and the nanoindentation, duplicated samples were collected from the dorsal wall, abaxial wall and pre-bulbar sole of the hoof capsule. Material collection was performed in 40 medial digits of thoracic limbs and 40 lateral digits of pelvic limbs. The bidimensional microtomography showed that the dorsal wall of the thoracic and pelvic limbs presented higher density, followed by the abaxial wall, and finally by the sole, with the lowest density. Moreover, the hoof capsule of cows of Girolando breed is a compact, non-porous material, and constituted by extratubular and intratubular keratin. By the tridimensional microtomography, it was possible to measure the angles of the corneal tubules in relation to the periople and the claws in the different regions of the hoof capsule, which were 90° for the dorsal wall, 55° for the abaxial wall and 70° for the sole. The tridimensional microtomography also showed corneal tubules of different diameters: 17, 51, 85, 119 and 153 μm. The nanoindentation test, when performed in different regions of the hoof capsule, did not reveal significant difference of Vickers hardness in the evaluated areas. However, we verified a larger elastic module of these regions on the transversal cut of the corneal tubules compared to the longitudinal cut.

  • Morphology of the thoracic limb of goat as evidenced by gross osteology
           and radiology
    • Authors: M. Makungu; B. Merere
      Abstract: The objective of this study was to provide the detailed normal gross osteology and radiographic anatomy of the thoracic limb in goats as a reference for clinical use and in biomedical research. Radiography of the thoracic limb was performed in five small East African goats. Radiographic findings were correlated with bone specimens from four adult small East African goats. The scapula was narrow. The major tubercle was large and extended proximally above the head of the humerus. The lateral supracondylar crest was less prominent. The lateral and medial epicondyles of the humerus were almost of the same size. The lateral surface of the lateral condyle of the humerus presented a prominent depression for the origin of extensors of the carpus and digits. The cranially located radial notch was deep seated and the radial tuberosity was represented by a rough area located nearer to the head of the radius. The fifth metacarpal bone was seen in all animals. The morphology of the thoracic limb of small East African goats indicated the presence of powerful extensor muscles and is restricted to forward and backward movements as an adaptation to terrestrial lifestyle.

  • Morphological Studies of the Tongue of the Egyptian Water Buffalo (Bubalus
           bubalis) and Their Lingual Papillae Adaptation for Its Feeding Habits
    • Authors: N. E. R. El-Bakary; M. M. A. Abumandour
      Abstract: This work was conducted to describe the morphological characters of the tongue of Egyptian water buffalo (Bubalus bubalis). The lingual root and the dorsal middle region of apex and body in addition to the dorsal and ventral surface of lingual tip were devoided from any fungiform papillae. The lingual tip contains conical papillae only. The ventral surface of lingual apex was divided into two portions by the U-shaped fungiform line into papillary and non-papillary region. Histological investigation on the lingual surface epithelium and lamina propria submucosa reflects differences in these layers in different parts of the tongue. By SEM, there are two subtypes of filiform papillae: caudally directed papillae on dorsal surface and rostrally directed papillae on the lateral region of ventral surface of lingual apex. There are two subtypes of conical papillae: small slightly rostrally directed papillae on dorsal and ventral surface of lingual tip and large posteromedially directed papillae on dorsal surface of lingual root. The rounded circumvallate papillae consisted of round bulb surrounded by deep circular groove, which surrounded by circular pad. Higher magnification of filiform papillae indicates the presence of microcrests separated by microgrooves, and these microgrooves consisted of microrodes. The fungiform surface having micropores on the tip of elevated tubercle for taste buds pores. All these observed structures (microcrests, microgrooves, microrodes, tubercles, microridges) in a higher magnification allow animals to transport food particles through the oral cavity and help in the defensive behaviour. There are strong correlations between the tongue anatomical characteristics and its functions.

  • Ultrastructural, Sensory and Functional Anatomy of the Northern Elephant
           Seal (Mirounga angustirostris) Facial Vibrissae
    • Authors: H. Smodlaka; I. Galex, L. Palmer, J. A. Borovac, W. A. Khamas
      Abstract: Vibrissae (whiskers) play a key role in underwater orientation in foraging phocids through vibrotactile sensation processing. Our aim was to evaluate the structure of northern elephant seal (NES) vibrissae by means of light (LM) and transmission electron microscopy (TEM), in order to elucidate their function. Vibrissal follicles were processed using standardized laboratory methods and LM/TEM techniques. Individual follicular axonal numbers were counted and axonal diameter measured and averaged. NES have mystacial, rhinal, supraorbital and labial vibrissae. The vibrissal follicles are histologically subdivided into a ring, upper and lower cavernous sinuses (LCS). Each vibrissa is innervated by the deep vibrissal nerve. The average number of axons per large mystacial vibrissa is 1804 (±123), rhinal 985 (±241), supraorbital 1,064 (±204) and 374 (±65) in labial vibrissa. The entire vibrissal system carries an estimated 148 573 axons, and mystacial vibrissae alone have 125 323 axons. Axonal conduction velocity for each vibrissal type is 55.26 m/s for labial, 56.58 m/s for rhinal and 35.88 m/s for mystacial vibrissae. TEM and LM revealed a plethora of mechanoreceptors within the vibrissal follicles: Merkel cell-neurite complexes, lanceolate and pilo-Ruffini end organs. A vast number of sensory axons projecting from the entire vibrissal system indicate that the vibrissal sensory area takes up a large proportion of phocids’ somatosensory cortex. In conclusion, NES has highly sensitive and finely tuned vibrotactile vibrissal sense organs.

  • Morphology and Classification of Right Ventricular Bands in the Domestic
           Dog (Canis familiaris)
    • Authors: L. A. Cope
      Abstract: Ventricular bands, also designated as ‘false tendons’, are described as single or multiple strands that cross the ventricles and have no connection to valvular cusps. Previous work indicates these strands are present in the ventricles of humans and some animal hearts and not always associated with cardiac pathologies. Despite these previous studies, the published literature is limited in documenting the morphology of these strands and incidence in animals. In this study, examination of 89 hearts showed six types of ventricular bands in the right ventricle of the domestic dog. These bands were classified according to their prevalence and points of attachment. Type I extended from the interventricular septum to the ventricular free wall, type II connected a musculus papillaris parvus to the ventricular free wall and type III connected trabeculae carneae on the interventricular septum. Type IV connected the trabeculae carneae on the ventricular free wall, type V interconnected papillary muscles and type VI connected the interventricular septum to a papillary muscle. While the study of these ventricular bands provided additional information on the cardiac anatomy of the domestic dog, it also showed their clinical importance. Several studies have proposed that their position in the ventricle may interfere with cardiac catheterization and pacemaker lead placement or be misinterpreted during echocardiography.

  • Morphologic and Cytochemical Characteristics of the Blood Cells of the
           Yellow-Bellied Slider (Trachemys scripta scripta)
    • Authors: J. D. Hernández; P. Castro, P. Saavedra, P. Ramírez, J. Orós
      Abstract: The increasing prevalence of yellow-bellied sliders (Trachemys scripta scripta) as pets in the European Union and also its utilization as animal models for experimental purposes makes crucial an accurate classification of their blood cells. The aim of this work was to provide a morphologic classification based on the cytochemical characteristics of the blood cells of 15 yellow-bellied sliders. Cytochemical stains included benzidine peroxidase, chloroacetate esterase, alpha-naphthyl butyrate esterase (with and without sodium fluoride), acid phosphatase (with and without tartaric acid), Sudan black B, periodic acid–Schiff and toluidine blue. Nuclear and cellular dimensions were also measured based on quick Romanowsky-type stained smears. Besides erythrocytes and thrombocytes, five types of white blood cells were identified: heterophils, eosinophils, basophils, lymphocytes and monocytes. The cytochemical patterns of heterophils, eosinophils and basophils were unique compared to those described for other chelonians. This paper provides a useful guideline for clinical settings and further haematological studies of this species.

  • Microstructure and Hardness of Buffalo's Hoofs
    • Authors: B. M. Assis; L. A. F. Silva, C. R.O. Lima, R. F. Gouveia, V. A. S. Vulcani, F. J. F. Sant'Ana, R. E. Rabelo
      Abstract: The aim of this study was to describe the microstructure of hoof capsules of the buffalo. In addition, the study emphasized the morphometric aspects of the horn tubules, the Vickers nanohardness of the dorsal and abaxial walls and sole of the digits of the thoracic and pelvic limbs of the buffalo. The abaxial wall in the thoracic and pelvic digits showed larger diameter of the horn tubules when compared to all dorsal wall and sole. In addition, the abaxial wall of the thoracic digits showed larger diameter of the horn tubules when compared with the pelvic digits. According to the three-dimensional microtomography, the dorsal wall was higher in density compared with the abaxial wall. The latter exhibited an intermediate density, while the sole showed the lowest density. The Vickers nanohardness test showed that there was no difference in hardness and resistance between the experienced regions. However, the elastic modulus was greater on the transversal section of the hoof capsule. In conclusion, the results of the current study show that modern technologies such as microtomography and subsequent imaging can be used to investigate details of the basic morphology in different regions of the buffalo's hoof.

  • Ultrastructure of Lingual Papillae in Common Chimpanzee (Pan troglodytes)
           Foetus, Newborn and Adult Specimens
    • Authors: J. F. Pastor; M. Barbosa, F. J. De Paz, I. San José, M. Levanti, J. M. Potau, J. A. Vega, R. Cabo
      Abstract: Among primates, the two recognized species of chimpanzees (common chimpanzee, Pan troglodytes; pygmy chimpanzee, Pan paniscus) are considered to be the most similar to humans. Importantly, in mammals, the food intake behaviour largely determines the tongue morphology, including the type, proportion and distribution of gustatory and non-gustatory tongue papillae. The lingual papillae form during its development and mature in post-natal life depending on the different feeding. In this study, we have used scanning electron microscopy to analyse the age-related changes in the lingual papillae of foetal, newborn and adult P. troglodytes. Four main types of lingual papillae, denominated filiform, fungiform, foliate and vallate, and one subtype of filiform papillae called conical papillae, were found. The main age-related changes observed in all kinds of papillae were a progressive keratinization and morphological complexity along the lifespan. During the foetal period, there was scarce keratinization, which progressively increases in young animals to adulthood. The number of filiform increased with ageing, and both filiform and fungiform papillae in adult tongues are divided into pseudopapillae. On the other hand, the vallate papillae vary from smooth simple surfaces in foetal tongues to irregular surfaces with grooves and pseudopapillae (microscopic papilla-shaped formations within the papilla itself) in adults. These results describe for the first time the age-related variations in the three-dimensional aspect of lingual papillae of the chimpanzee tongue and provide new data to characterize more precisely these structures in the human closest specie.

  • Facets of Clinical Appearance and Aetiology in an Unusual Bovine Amorphus
    • Authors: J. Weber; N. Rudolph, M. Freick
      Abstract: Amorphus globosus is a rare entity, more common in the cow but also reported in mares, buffaloes and goats. In respect of both development and clinical presentation, this abnormity can be evolved very variably. Previously, it has been discussed whether it is a form of twin pregnancy or placental teratoma. This case report deals with morphology and genetic observations in an unusual bovine amorphus globosus exhibiting a rudimentary clitoris and vulva, gut-like structures and rudimentary bones. The amorphus globosus was shown to be dizygotic to the normal male twin using the BovineSNP50 v2 BeadChip and had a genetical female sex. Aspects of aetiology and pathogenesis as well as the possible impact of amorphus globosus in the emergence of freemartinism are discussed.

  • Development of the New Zealand White Rabbit Eye: I. Pre- and Postnatal
           Development of Eye Tunics
    • Authors: M. Abdo; S. Haddad, M. Emam
      Abstract: The New Zealand white (NZW) rabbit has been and is right now regularly utilized in ophthalmic surgery evaluation. Inside NZW rabbit eye, the visibility of ocular structures throughout surgical procedure is fantastic. Younger rabbits are used in different ages for the evaluation of ophthalmic surgery. Complete studies of ocular development in the NZW rabbits have not been reported previously. The aim of the present investigation was to describe the major landmarks and the time course of the pre- and post-natal development of the complete eye tunics of the NZW rabbit to give a superb model as well as a fruitful area for further ophthalmological investigations. Serial histological sections of NZW rabbit prenatal (E13–E28) and post-natal (P1–P14) stages were examined, respectively. The eye of the NZW rabbit developed in a similar manner to that of the human and domestic animals eyes; the principal differences were at the time of occurrence of certain developmental events, absence of pigmentation which represent an exploited benefit for ophthalmic surgery, remarkable Bowman's membrane at E25, poor developed ciliary stroma and juvenile retinal layer until P9. In human, the basic morphogenetic processes of the development of eye tunics are completed towards the end of the first half of gestation period. However, the latter represents the beginning stage of the development of eye tunics in the rabbit. Thus, allowing various extensive ophthalmic researches to be performed.

  • Expression of hLAMP-1-Positive Particles During Early Heart Development in
           the Chick
    • Authors: T. H. Abd-Elhamid; M. L. Conway, A. R. Sinning
      Abstract: Heart development requires coordinated activity of various factors, the disturbance of which can lead to congenital heart defects. Heart lectin-associated matrix protein-1 (hLAMP-1) is a matrix protein expressed within Hensen's node at Hamburger–Hamilton (HH) stage 4, in the lateral mesoderm by HH stages 5–6 and enhanced within the left pre-cardiac field at HH stage 7. At HH stages 15–16, hLAMP-1 expression is observed in the atrioventricular canal and the outflow tract. Also, the role of hLAMP-1 in induction of mesenchyme formation in chick heart has been well documented. To further elucidate the role of this molecule in heart development, we examined its expression patterns during HH stages 8–14 in the chick. In this regard, we immunostained sections of the heart during HH stages 8–14 with antibodies specific to hLAMP-1. Our results showed prominent expression of hLAMP-1-positive particles in the extracellular matrix associated with the pre-cardiac mesoderm, the endoderm, ectoderm as well as neuroectoderm at HH stages 8–9. After formation of the linear heart tube at HH stage 10, the expression of hLAMP-1-stained particles disappears in those regions of original contact between the endoderm and heart forming fields due to rupture of the dorsal mesocardium while their expression becomes confined to the arterial and venous poles of the heart tube. This expression pattern is maintained until HH stage 14.This expression pattern suggests that hLAMP-1 may be involved in the formation of the endocardial tube.
