in the central area of mass. Many tumor cells had invasive tendency to adjacent tissues. These characteristic histopathologic features were consistent with cutaneous histiocytic sarcoma. IHC revealed that the tumor cells expressed positive reactions for vimentin, lysozyme, MHC class Ⅱ,CD18, and Iba-1, but negative for CD3, CD79 α and E-cadherin. Conclusions: Histiocytic sarcoma is a round... -

leukocyte antigens characteristic of dendritic cell differentiation including CDla, CD1c, and CD11c [2]. By contrast to the high prevalence of histiocytoma in the dog, cutaneous histiocytoma is very rarely recognized in the cat and the tumor does not feature in the majority of published surveys of feline cutaneous neoplasia [1]. In the study, we describe the histopathologic characteristics... -

syringohydromyelia because characteristic changes of the diameter or area ratio between spinal cord and vertebral canal can provide useful information for differentiating these cervical diseases. The ratio of the diameter of spinal cord to that of vertebral canal in the cervical vertebra has been previously evaluated using radiographic myelography [6]. In the present study, we measured the... The height, width, and cross-sectional area of the vertebral canal and spinal cord along with the area ratio of spinal cord to vertebral canal in the cervical vertebra were evaluated in images obtained using computed tomography (CT). Measurements were taken at the cranial, middle, and caudal point of each cervical vertebra in eight clinically normal small breed dogs (two shih tzu, two miniature schnauzers, and four mixed breed), 10 beagles, and four German shepherds. CT myelography facilitated... -

melamine. (C) Cell number decreased evidently and cellular shape became irregular when the melamine concentration was 0.25 mg/mL. Characteristic cell atrophy appeared. (D) Cell number decreased drastically and many cells were damaged when the melamine concentration reached 2.5 mg/mL. ×40. melamine concentration increased, the growth of T. pyriformis was inhibited and its generation time was... This study assessed the toxicity of melamine against the unicellular eukaryotic system of Tetrahymena (T.) pyriformis exposed to 0, 0.05, 0.25, 0.5, 2.5, and 5 mg/mL of melamine. Cell growth curves of different cultures, the half maximum inhibition concentration (IC50) value of melamine, and morphological changes in cells were obtained via optical and transmission electron microscopic observation. The effects of eleven melamine concentrations, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5 and 5... -

term that takes into account the characteristic histologic features of the tumour and does not refer to its behaviour that can be benign or malignant. Although the case was histologically categorised as a low grade malignancy, it exhibited biological features of a high grade malignancy, as it metastasised to the lungs and caused extremely severe cerebral and cerebellar compression that led... Multilobular tumour of bone (MTB) is an uncommon tumour and is usually located in the skull. A 13-year-old mixed breed dog was presented with a two-week history of progressively worsening vestibular dysfunction and cognitive abnormalities; it appeared demented and showed asymmetric ataxia and hypermetria of all limbs. The owner opted to have the animal euthanised. Necropsy revealed a large mass occupying the right occipital, parietal and temporal bones, severely compressing the cerebellum and... -

in the lymph nodes. Characteristic liquefaction, calcification, and laminated, caseous abscess were not observed in this case. The numbers of acid-fast bacteria were extremely abundant in lung and lymph nodes than in cattle. These findings are consistent with previous reports [4, 16]. M. bovis transmission and susceptibility of individual animals to the organism are influenced by host genotype and... in diameter were scattered in the whole lung. Bronchial and mediastinal lymph nodes were also enlarged. Histopathologically, lungs had typical classical tuberculous granulomas, multiple abscesses, and numerous macrophages and Langhans giant cells infiltration in alveolar lumen. In the lymph nodes, there were small clusters of necrosis and infiltration of numerous macrophages, epithelioid cells, and Langhans giant cells. With the acid-fast staining, numerous mycobacteria were revealed in the lung... -

B cells， pancreatic acinar cells， hematopoetic RBL cells， and nonsecre tory CHO fibroblasts. Each type of cell shows a characteristic time course of exocytosis and endocy tosis. However， one feature was shared by all secre tory cells: the existence of two components of exocy tosis with markedly different time constants. Ampero metric measurements indicated that L V exocytosis was... -

By the 7 ~ 10 days after injury, the animals were producing extensive simultaneous movements of the hip, knee and ankle.

dent acidification was determined in the presence or absence of Na 3V04. As shown in Fig. 9, only early · endosomes exhibited the vanadate dependent sti- mulation of acidification activity, characteristic of the vanadate-mediated inhibition of Na+-K+-ATPase. ..PAGE:9 -Isolation and Chracterization of Endosome Subpopulation - 205 .. l! ., u .. ! 0 ::s ii: g IL ~ ., u .. ! 0 ::s ii: g... Endosomes lower their internal pH by an ATP-driven proton pump, which is critical to dissociation of many receptor-ligand complexes, the first step in the intracellular sorting of internalized receptors and ligands. Endosomes are known to exhibit n great range of pH values that can vary between 5.0 and 7.0 within a single cell although the factors that regulate endosomal pH remain uncertain. To evaluate the morphological and topological differences of endosomes in the different stages, confocal... -

Kim A i 200 mg BK0.04M B 1200 mg BK0.04M C I 200 mg PAD5M BK0.04M Fig. 1. Effects of _bradykinin on the isometric con- tractions of guinea-pig gastric smooth muscle. A. Bradykinin induced characteristic contractile respon- ses, which are composed of a rapid contraction-transient relaxation-slowly developing contraction. B. Bradykinin- induced contraction was not changed by pretreatment... a calcium-releasing action of bradykinin front the intracellular calcium pool, because such change was blocked by pretreatment with caffeine. Bradykinin-induced contraction was also blocked by pretreatment with caffeine. From these results, it is suggested that bradykinin induces a calciumrelease and contraction through the B2 receptor of guinea-pig gastric smooth muscle. Enhancement of slow wave activity is an indirect action of bradykinin through enteric nerve cells embedded in muscle strip.
