Zur Genesis des myozytären Bewegungsapparates
Authors: Preuss F. 
Published: June 2007

AbstractLiving beings not only have measurable, but also unmeasurable (psychologic) dimensions. The latter are illustrated by the directing of the myocytic locomotor apparatus. All parts of the morphologic and physiologic reflex arch obey determined psychic influences about which can be drawn conclusions upon behavior. The analysis of these influences reveals the reflex arch to be a response angel, the perception or sentiment side and the expression or feeling side of which are governed by the vertex as the switching or decision center. The origin of the two sentiments (delight and dislike) and the two feelings (hate and love) is derived biologically.

Morphology of the Vesicular and Bulbourethral Glands in Barrows and the Changes Induced by Diethylstilboestrol
Authors: Lauwers H. , Nicaise M. , Simoens P. , Vos N. R. De 
Published: June 2007

AbstractThe macroscopic and light microscopic structure of the vesicular and bulbourethral glands was investigated in male pigs, which were castrated early in life and examined at slaughter weight. The vesicular glands showed a constant morphological pattern while in the bulbourethral glands an individual variation was observed in the number of mucous acini and the amount of interstitial tissue. In spite of this variation in the normal structure, the latter gland as well as the vesicular gland showed reliable changes after treatment with diethylstilboestrol.
Histochemische Untersuchungen an der Klauenepidermis des Schweines
Authors: Von Geyer H. 
Published: June 2007

AbstractThe unaltered epidermis of the hoof of 21 Landrace pigs of different ages was examined histochemically for substances which could be important for normal keratinization, quality of horn or in pathological processes. These were PAS‐positive substances, SH‐ and SS‐groups, lipids, calcium and phosphate as well as the enzymes lactate dehydrogenase, succinate dehydrogenase, ATP‐ase, alkaline and acid phosphatase, beta‐glucuronidase and non‐specific esterase. The histochemical results can be very different in various pans of the hoof. The medullary spaces of the horn tubules in the stratum corneum contain carbohydrates as well as hydrolytic enzymes such as acid phosphatase, beta‐glucuronidase and non‐specific esterase. These enzymes and the carbohydrates may increase in pathological processes.
Localization of the Motoneurons Innervating the Hindlimb Muscles in the Spinal Cord of the Domestic Fowl
Authors: Ohmori Yasushige , Watanabe Tohru , Fujioka Toshitake 
Published: June 2007

AbstractThe origins of the motor nerve fibers supplying the individual hindlimb muscles were elucidated in the fowl by the retrograde degeneration method. Chromatolytic cells were seen in the ipsilateral lamina 9 of the lumbosacral enlargement. Motoneurons innervating the individual hindlimb muscles were localized in the characteristic position of lamina 9. Both hip and thigh muscles are supplied by motoneurons of almost all the columns in lumbar segments and by those of dorsolateral columns in sacral segments, while the shank and foot muscles are supplied by motoneurons of ventromedial columns in sacral segments. The origins of the dorsal cord of the lumbosacral plexus are situated laterally in the lamina 9 and those of the ventral cord are located medially in it.

Histologische und ultrastrukturelle Untersuchungen am Vaginalepithel des Rindes
Authors: Wrobel K.‐H. , Laun G. , Hees H. , Zwack M. 
Published: June 2007

SummaryHistological and electron microscopical examinations of the vaginal epithelium of the cowThe vaginal epithelium of the cow was not uniform. Its structure depended on the place from where a sample was taken, the hormonal status of the animal, and other (individual) factors. From each of 23 cows 11 tissue samples were taken at equal distances from the entire length of the vagina. Some cows had low blood hormone values, others were under gestagen dominance and still others under the influence of estradiol. In cows with low blood hormone values, tissue samples 1 and 2 (E 1 and E 2), which corresponded to the fornix and its junction with the vagina proper, showed an epithelium of one or two layers of cylindrical cells. Tissue samples E 3 to E 5 (cranial half of the vagina) were dominated by an epithelium consisting of three layers, i. e. two layers of basal cells and one variably shaped layer of apical cells. In E 6 to E 10 (caudal half) the height of the epithelium increased from three to about ten cell layers; a stratum intermedium of variable thickness could be discerned. Tissue sample Ell (vestibule) had a non‐cornified squamous epithelium of multiple layers. Cows under the influence of gestagen had an epithelium which in principle was similar to the above findings. In cows under the influence of estradiol, the rate of cell proliferation was increased, the epithelium was thicker throughout, showed an active tendency of desquamation, and that in the vestibule had the potential to become cornified. Free cells (lymphocytes and plasma cells) were found in all areas; they were more numerous in animals under the influence of gestagen. In animals under the influence of estradiol also neutrophils were encountered.PAS‐positive mucosubstances containing acid groups were found in the apical cells of the cranial end of the vagina. These substances could be responsible for a typical reaction (Kuppenreaktion) in the epithelial type that featured a stratum intermedium. Apart from folds the vaginal epithelium contained genuine intraepithelial and subepithelial glands.
Licht‐ und elektronenmikroskopische Untersuchungen der Samenblasendrüse (Glandula vesicularis) des Bullen
Authors: Amselgruber W. , Feder F.‐H. 
Published: June 2007

SummaryLight and electron microscopical study of the vesicular gland of the bullThe vesicular glands of six adult bulls were studied grossly and with the microscope. Corrosion casts (of the duct system) examined with the dissecting microscope and the SEM clearly showed that the gland was tubulo‐alveolar.The light microscope showed two rows of tall glandular cells. The basal epithelial cells (termed “dwarf lipid‐cells”) contained uni‐ as well as plurivacuolar lipid droplets. In the tall glandular cells fine lipid droplets were seen mainly in the supranuclear cytoplasm.Electron microscopical examinations permit division of the tall glandular cells into three compartments, shown in a semischematic drawing. The results of this study allow the conclusion that the basal “fat cells” and the peroxysomes of the tall glandular cells are related to the formation of prostaglandins.
Electrophysiologic Studies of the Cutaneous Innervation of the External Genitalia of the Female Dog
Authors: Spurgeon T. L. , Reddy V. K. 
Published: June 2007

SummaryThe cutaneous innervation of the external genitalia of the female dog was studied using electrophysiologic recording of evoked afferent activity in peripheral branches of the caudal cutaneous femoral, superficial perineal, and genitofemoral nerves, and the dorsal nerve of the clitoris. The observed cutaneous distribution was comparable to that of the male dog, with expected but relatively minor variation due to differences in morphology of the external genitalia. A speculative developmental sequence for the cutaneous innervation of the external genitalia was presented incorporating the distribution of the nerves studied to homologous structures between the sexes.
über die Adenosintriphosphatasen des fetalen Dickdarmepithels Licht‐ und elektronenmikroskopische Untersuchungen am Caecum des Rindes (Bos primigenius taurus)1,2
Authors: Wille K.‐H. 
Published: June 2007

SummaryThe adenosintriphosphatases of the fetal large intestinal epithelium. Light and electron microscopical studies of the bovine cecum (Bos primigenius taurus)Light and electron microscopical examinations were made of the Mg++‐, (Mg++‐Na+‐K+)‐ and the Ca+‐ATPases on the cecal epithelium of bovine fetuses.The light microscope revealed the substances as continuous black lines, occupying in the area of the villi the entire height of the epithelium and in the area of the crypts only the apices of the cells. The electron microscope often revealed granules on inter‐ and perigranular cytoplasmic structures of the goblet cells. In concert with the light microscopical finds, however, the precipitates were found primarily as continuous black between the microvilli on the outer layer of the plasmalemma both in the area of the villi and of the crypts. The lateral cell borders of the epithelial cells showed intercellular reaction products only in the areas of the villi; there were also marked unspecific intracellular reactions. Cell junctions and desmosomes were always free of precipitates.It was not possible to demonstrate further stimulation of the Mg++‐dependent basic activity by Na‐ and K‐ions, neither was it possible to see differences in activity and locale between the Mg++‐activated and the Ca++‐ATPase. Generally, the intensity of the reactions was remarkably and evenly strong during the entire fetal period examined.An attempt was made to interpret different functional aspects of these enzyme complexes, possibly related to transport activity of these fetal intestinal epithelial cells.

Authors: Chamorro C. A. , Paz P. de , Fernandez J. G. , Fernandez M. , Villar J. M. 
Published: June 2007

SummaryHead mesoderm cells from chick embryo at stage 10 were cultured onto coverslips. The mesoderm cells with bipolar aspect were studied by means of scanning electron microscopy. Several features of the filopodia and lamellipodia of these cells, as number, length and width were quantified and the results ire discussed in view of the role proposed for these projections in the cellular locomotion. Moreover, the morphological characterization here carried out permits to have comparison with other cellular types of the same culture or between cultured cells of different stages of chick embryo development.
Evolución morfológica en el epitelio seminífero del Cerdo en diferentes edades (Sus scrofa de la raza Landrace)*
Authors: Orsi A. M. , Dias S. Mello , Moreira J. E. , Camilli J. A. 
Published: June 2007

SummaryThe morphological development of the seminiferous epithelium in the pig at different ages (Sus scrofa, Landrace breed)In the Pig, Landrace breed, were observed, at different ages, among 15 to 210–220 days, the morphological patterns of the seminiferous epithelium that lines “cordonal” tubules at 15 to 30 days of postnatal and “luminal” tubules at 120 to 210–220 days of age. Although some morphological events of cellular differentiation were observed at 120 days, and the spermatogenesis process apparently could be observed at 180–190 days, really the overall characteristics of the cellular differentiation in the seminiferous epithelium, with the presence of luminal spermatozoa, were observed at 210–220 days of age. This last stage is considered as the puberal age.
Das Wollen und Wissen der Tiere als evolutionstheoretischer Forschungsgegenstand
Authors: Preuss F. 
Published: June 2007

SummaryWill and knowledge of animals as topic of evolution‐theoretical investigationsOnly living beings have a will for action, and all living beings with the exception of man can will nothing else but to survive. The innate will drives them to self‐preservation, species‐preservation, and self‐organization. Only man can renounce to do so. This uniform will is supported by the most differentiated knowledge. In cells this knowledge is chemical and by sensation; in animals it is physical and by sensation. It senses and remedies three bodily needs: hunger, disease, and propagation. Only know‐how can remedy needs. The need for knowledge is therefore the primary need, and improvement of knowledge is the decisive evolutionary change.Chemical knowledge by sensation in most cases is genetic, ground‐conscious, and hereditary knowledge. In physical knowledge acquired by sensation, ground‐consciousness is lifted to the instinct‐conscious level of the nerve cells through which learning‐consciousness is developed further. The laws governing this are described elsewhere.

A Morphologic and Biochemical Evaluation of the Spider Syndrome in Suffolk Sheep
Authors: Troyer D. L. , Thomas D. L. , Stein L. E. 
Published: June 2007

SummaryThe distal radial growth plates of six pairs of spider‐affected and non‐affected lambs were compared after light and electron microscopic evaluation. Light microscopy revealed regions within the spider‐affected physes that lacked the distinctly columnized appearance of the normal ones. However, provisional calculation as revealed by von Kossa staining did not differ between the two groups; nor were there marked ultrastructural differences between control and spider lamb growth plate chondrocytes or matrices. The spider growth plates were also studied after concanavalin A and wheat germ agglutinin lectin histochemistry. Intracellular and extracellular staining patterns did not differ from previously reported normal patterns. Finally, SDS‐PAGE analysis of collagen extracted in the native state from spider‐affected cortical bone revealed that it is comprised of type I collagen that is normal in its primary structure; furthermore, there is no type III collagen present.
The Arterial Supply of the Male Reproductive System in the Hamster
Authors: Rerkamnuaychoke W. , Kurohmaru M. , Nishida T. 
Published: June 2007

SummaryThe major arteries, the testicular, deferential, prostatic, internal pudendal and external pudendal arteries, supply the male genital organs of the hamster. The same arterial patterns are found in three strains, except that the external pudendal artery arises from the external iliac artery or internal iliac artery in the APG strain, but only from the external iliac artery in the CBN and ACN strains. The deferential and prostatic arteries form the arterial loop on the dorsal surface of the ventrolateral lobe of the prostate. This loop may play some importance parts in the functional interaction between the epididymis and the prostate. The caudal epididymal artery arises more frequently from the spermatic cordai portion of the testicular artery than from the cranial epididymal artery, and it never arises directly from the abdominal part of the testicular artery as reported in the rat, mouse and rabbit. The deferential artery may join with the cranial vesicular artery to form the common trunk (umbilical artery), but sometimes these arteries arise directly from the internal iliac artery.
Morphogenesis of the Epithelium and the Lamina Propria of the Rumen in Bovine Fetuses and Neonates
Authors: Amasaki H. , Daigo M. 
Published: June 2007

SummaryDevelopmental changes in the mucous membrane of the rumen in bovine fetuses were observed by scanning electron microscopy (SEM). The ruminal epitheliums were obtained from 20 bovine fetuses and 4 bovine neonates. The samples were divided into 3 groups. Group 1 was examined in the epithelial surface by SEM. Group 2 was examined in the surface of the lamina propria and the reverse face of the epithelium by SEM, after having separate the epithelium from the lamina propria by Scallata's PBS‐EDTA method. Group 3 was examined in histological aspect.The ruminal papillae appeared first in early in the 5th month of gestation. On the other hand, the papillae of the lamina propria appeared first in early 4th month or late 4th month of gestation. It seemed that the formation of papillae in the lamina propria always preceded that of ruminal papillae. Meanwhile, some epithelial cells were exfoliated from the ruminal surface cells during late 4th month to early 5th month of gestation. Ruminal surface cells came to have keratohyaline granules from the 5th month of gestation onward.
Chromogranin‐ and Somatostatin‐containing Neuroendocrine Cells in the Porcine Uterus An Immunocytochemical Study
Authors: Vittoria A. , Paino G. , Mura E. la , Budetta G. , Cecio A. 
Published: June 2007

SummaryEndocrine cells scattered in organic mucosae were defined “Neuroendocrine” (NE) cells because they constitute a section of the Diffuse Neuroendocrine System (DNES). Such cells have never been evidentiated in the normal endometrium. By means of histochemical and immunohistochemical techniques NE celis, some of which contain the hormone somatostatin, are described in the glandular epithelium of the uterine horn in non‐pregnant, non‐castrated, young and adult sows. As is known, the uterine horn is the organ of pregnancy in the pig. The localization, distribution and morphology of the uterine NE and somatostatin‐containing cells are reported and the importance of their function, in the pregnant and non‐pregnant porcine uterus, is mooted.
