Abstract

Primary lung cancers, or tumors originating in the lung, are relatively uncommon in dogs. The objectiveof this study was to describe the canine lung carcinoma that serially transplanted into severe combinedimmunodeficiency (SCID) mice, in order to established cell line from this tumor cell.  Morphology andcharacteristic of this canine lung carcinoma in SCID mice by histopathological and ultrastructuralexaminations with metastatic lesion in lung were also examined.  Histopathologically, the tumor masswere consisted of cuboidal to columnar cells with papillary pattern, uniform in size, the nuclei were oftenvariable in size, and some cells have vacuole on their cytoplasms.  Glandular forms were predominant withlobulated pattern, ductal pattern with papillary injected into tube-like structure were also encountered.Mitotic figures commonly found with inflammatory reaction were sometimes present in the interstitiumand lumen gland.  Ultrastructural analysis of the tumor cells showed round to oval cells with one or moreprominent nucleoli.  The cells possessed numerous mitochondria, smooth endoplasmic reticulum, andindividual cells which were interconnected via desmosomes.  Tonofilament characterize by long cytoplasmicmaterial was encountered.  Positive reaction of the round to oval tumor cells to anti keratin antibodyconfirmed that their epithelial cell nature.  Lung metastatic lesions were found in SCID mice aftertransplantation and this phenomenon indicated that canine lung carcinoma is tumorigenic to SCID mice.

Abstract

Physiological aging or aging due to oxidative stress decrease glutathione level in the hippocampuswhich impacts the respons impaired hippocampus celuller. Hippocampus cellular respons disorderscharacterized with decreased viability, increased mortality, and the shortening of the axons of neurons.One way to improve hippocampus cellular respons is to  increase the levels of glutathione and theconcentration of glutathione precursor. One compound that provides glutathione precursors is alanine-glutamine dipeptide. This research was designed to obtain the improve of hippocampus cellular responsresult from the administration of 7% alanine-glutamine dipeptide concentration of aged or oxidative-stressed rats. The improvement of hippocampus cellular respons affect  the improvement of the hippocampus function. The experimental rats were assigned into a completely randomized design consisted of threefactors with 2x2x2 factorial arrangement. The first factor was the age of the experimental rats, consistedof two levels i.e., 12 and 24 months. The second factor was oxidative stress consisted of two levels, i.e.,without and with oxidative stress. The third factor was alanine-glutamine dipeptide administrationconsisted of 2 concentrations, i.e. 0% and 7%. The results showed that  administration of 7% alanine-glutamine dipeptide improved level of glutathione in the hippocampus either in younger (58,76%) or aged(125,81%) rats or in normal (76,47%) and in oxidative-stressed rats (97,26%). These antioxidant hadmediated the respons improve viability, mortality, and long axons responses of neurons at younger (4,11%,37,07%, and 12,58%) or aged (6,91%, 37,85%, and 32,84%) rats, in normal (3,25%, 29,21%, and 21,04%)and oxidative stress (7,80%, 43,01%, dan 25,56%) rats. This research concluded that the alanine-glutaminedipeptide 7% increased glutathione levels.  This increased level affected the improvement of cellularresponds in aging hippocampus, physiological aging, or aging due to oxidative stress in rats.

Abstract

Study of the pathogenicity of gumboro virus (very virulent Infectious Bursal Disease virus, vvIBDV) oflocal isolates was performed in broilers. The chickens were grouped into four: i) infected with vvIBDV; ii)vaccinated with commercial vaccine + challenge with vvIBDV; iii) vaccinated using locally produced vaccine+ challenged with vvIBDV; and iv) control group (unvaccinated animals). Pathogenecity was analyzedbased on the sequence of infection; the distribution and degree of gross pathology and histopathologylesions on bursa Fabricius, spleen and thymus in relation to the presence of the antigen (IBDV Ag) whichwas detected using immunohistochemistry technique. During the acute phase (1-3 days following theexperimental infection) hyperemia and exudation on the bursa Fabricius were observed in the infectedgroup and the two vaccinated-challenged groups. Similarly, hyperemia was also observed on the spleenand thymus. Whilst during the chronic stages (at 7 and 14 days following the experimental infection) thebursa showed atrophy. Upon histological examination, the bursa showed interstitial edema, hemorrhage,infiltration of heterophyl cells and fibroblast hyperplasia. The bursa lymphoid follicles were depleted dueto cells necrosis and apoptosis. Plica epithelial layer was wrinkled and the Goblet cells metaplasia formedhyper plastic cysts. In the spleen and thymus severe reticulo endothelial cells proliferation was observedduring the acute stage and tended to decline during the chronic stage. During the acute and chronic stagescells containing IBDV Ag were detected in the bursa Fabricius, distributed within the mantle zone andgerminal center of lymphoid follicles in the two vaccinated-challenge groups. Whereas in the infectedgroup, the IBDV antigen were detected up to 7 days post the infection. Nevertheless, neither IBDV antigenwas detected in the spleen nor in the thymus in all the experimental groups. The results of this studyclearly explained the ferocity of vvIBDV of local isolates.
