1. Experimental autotransplant of spleen / Autotransplante experimental de baço
The spleen is a lymphoid organ that plays important part in the organism defense, participating in filtration processes, phagocytosis and immunoglobulin production. Histologically, is formed by a stroma and the parenquima being its cellular arrangement differentiated in white and red pulps. The main cellular types in the splenic structure are: T and B lympho

2. The subcutaneous auto-transplantation ovaries and follicular depletion in domestic catas (felis catus) / Autotransplantação de ovário no subcutâneo e consumo folicular em gatas domésticas (felis catus)
The main goal of this study was to establish the follicular depletion of the remaining and implanted ovaries in the subcutaneous in domestics cats after 120 days, by quantification and morphometric classification, and with respect to the preservation of the tissue organization. Thirteen female domestic cats (Felis catus) were used, distributed into two group

3. The subcutaneous auto-transplantation ovaries and follicular depletion in domestic catas (felis catus) / AutotransplantaÃÃo de ovÃrio no subcutÃneo e consumo folicular em gatas domÃsticas (felis catus)
O objetivo desse estudo foi estabelecer o consumo folicular do ovÃrio remanescente e do implantado no subcutÃneo de gatas domÃsticas apÃs 120 dias pela quantificaÃÃo e classificaÃÃo morfomÃtrica dos mesmos e em relaÃÃo à preservaÃÃo da organizaÃÃo tecidual. Foram utilizadas treze gatas (Felis catus), sem raÃa definida, distribuÃdas em dois

4. Avaliação dos efeitos tóxicos do cianeto e do tiocianato no período perinatal. Estudo em ratos / Evaluation of toxic effects of cyanide and thiocyanate during perinatal period. Study in rats
The aim of the present study was to determinate the toxic effects of long-term exposure to KCN and KSCN in rats, during perinatal period. Initially, it was achieved the toxicokinetics study of the thiocyanate in female rats, in three different physiological states: estrogenic, gestation and lactation. These animals received, per os, in the drinking water or

5. Transitional Versus Surgical Menopause in a Rodent Model: Etiology of Ovarian Hormone Loss Impacts Memory and the Acetylcholine System
Clinical research suggests that type of ovarian hormone loss at menopause influences cognition. Until recently ovariectomy (OVX) has been the primary rodent model to examine effects of ovarian hormone loss on cognition. This model limits evaluations to abrupt and complete ovarian hormone loss, modeling less than 13% of women who receive surgical menopause. T

6. Pathogenesis of classical swine fever: B-lymphocyte deficiency caused by hog cholera virus.
Hog cholera, also known as classical or European swine fever, is caused by hog cholera virus, a member of the genus Pestivirus. It is shown here that the end stage of lethal infection in the natural host is associated with a dramatic depletion preferentially of B lymphocytes in the circulatory system as well as in lymphoid tissues. Already at the onset of di

7. Lymphocyte Depletion in Ileal Peyer’s Patch Follicles in Lambs Infected with Eimeria ovinoidalis
A total of 14 lambs were experimentally infected with Eimeria ovinoidalis in two separate experiments in two consecutive years. Nine lambs served as uninoculated controls. Material was collected from the ileum 2 weeks after infection in eight lambs and 3 weeks after infection in six lambs. Lambs examined 2 weeks after infection had normal follicles. After th

8. Reaccumulation of thyroglobulin and colloid in rat and mouse thyroid follicles during intense thyrotropin stimulation. A clue to the pathogenesis of colloid goiters.
Since Marine's observations some 50 years ago, it has been generally accepted that colloid goiters invariably result from colloid repletion of originally hyperplastic goiters after cessation of the goitrogenic stimulus. However, clinical observations suggest that many goiters never go through a stage of hyperplasia, but are colloid-rich from the beginning. W

9. Establishment of gastric Campylobacter pylori infection in the neonatal gnotobiotic piglet.
Campylobacter pylori, a gram-negative microaerophilic bacterium, has been implicated in the genesis of human gastritis, dyspepsia, and gastroduodenal ulceration. Previous attempts to reproduce the diseases in conventional laboratory animal species have been unsuccessful. To determine if neonatal gnotobiotic piglets were susceptible to C. pylori, we orally ch

10. Role of M cells in initial antigen uptake and in ulcer formation in the rabbit intestinal loop model of shigellosis.
Strains of Shigella flexneri with different invasive and pathogenic potentials were inoculated into the intestinal lumen of acutely ligated loops in nonimmune rabbits. After 90 min, tissues processed for ultrastructural as well as light microscopy showed that the bacilli were phagocytosed by M cells over lymphoid follicles of Peyer's patches and carried in v

11. An HIV-1 transgenic rat that develops HIV-related pathology and immunologic dysfunction
We report, to our knowledge, the first HIV type 1 (HIV-1) transgenic (Tg) rat. Expression of the transgene, consisting of an HIV-1 provirus with a functional deletion of gag and pol, is regulated by the viral long terminal repeat. Spliced and unspliced viral transcripts were expressed in lymph nodes, thymus, liver, kidney, and spleen, suggesting that Tat and

12. BAFF: a local and systemic target in autoimmune diseases
BAFF (B lymphocyte activating factor of the tumour necrosis factor family) is a vital homeostatic cytokine for B cells that helps regulate both innate and adaptive immune responses. Increased serum levels of BAFF are found in a number of different autoimmune diseases, and BAFF is found in inflammatory sites in which there is lymphoid neogenesis. BAFF antagon
