| ABSTRACT This study aimed to determine the histological features of the endometrium of bitches, as well as the cell proliferation at specific moments of diestrus, 10, 20, 30, 40, 50 and 60 days post ovulation, correlating the endometrial thickness with the uterine cell proliferation and the metabolic state (weight, blood glucose and plasma cholesterol) of the animals. Therefore, the right and left uterine horns of 26 clinically healthy bitches submitted to ovariohysterectomy were histologically analyzed 10, 20, 30, 40, 50 and 60 days post ovulation. The hematoxylin-eosin and AgNOR staining techniques were performed. All parameters were evaluated by ANOVA and post-hoc Tukey test (p<0.05). The correlation between endometrial thickness and uterine cell... |

| Mitotic index, nuclear diameter, number of nucleolar organizing regions, and Ki-67 expression, in hair follicle tumors of 82 dogs were evaluated. Tissue specimens were used to prepare sections for histological staining for number of nucleolar organizing region and immunohistochemical staining for Ki-67. Tumors were classified as trichoblastoma (n=32), benign trichoepithelioma (n=30), pilomatricoma (n=7), malignant trichoepithelioma (n=6), infundibular keratinizing acanthoma (n=5), and tricholemmoma (n=2). Head, dorsum, and limbs were the most affected sites. Malignant trichoepithelioma presented significantly higher mitotic index, number of nucleolar organizing regions and Ki-67 expression. Regarding benign neoplasms, trichoblastoma presented significantly... |

| Twenty BALB/c mice were inoculated with cell suspension of Ehrlich tumor. Ten mice were inoculated in the cushion plant (solid form) and the other 10 in the peritoneum (ascitic form). Animals were euthanized on different times (7 and 14 days). Cytological and histological slides, immunohistochemical (PCNA) analysis and NORs silver impregnation technique were performed. The results showed more proliferation on the 7th day in the ascitic form and on 14th day in the solid form, using both analyses (PCNA and AgNORs). The alterations observed in the Ehrlich tumors proliferation activity suggested that the growth curve is different between ascitic and solid forms. In the first one, the proliferation peak occurs on the seventh day and in the solid tumor the... |

| Adult male mongrel dogs were subcutaneously transplanted with the canine transmissible venereal tumor (TVT) on the hypogastric region. Twelve specimens of tumors were collected, half during the proliferative phase and the other half during the regressive phase. Fragments of the tumor were fixed in 10% buffered formalin and routinely processed for light microscopy. Sections of 4µm were stained by Schorr or AgNOR or either immunostained for MIB1 (Ki67). Schorr stain, AgNOR and MIB1 showed an increased proliferative activity through mitotic index, nuclear argyrophilic protein stain and cycling tumoral cells in the growing tumors, respectively. All of the three cell proliferation markers were able to distinguish the TVT in both evolution phases. MIB1... |

| Quarenta e cinco mastocitomas cutâneos caninos foram graduados histologicamente com o uso de hematoxilina-eosina. Foram empregados os métodos azul de toluidina e região organizadora nucleolar argirofílica (AgNOR) para, respectivamente, evidenciar os grânulos citoplasmáticos e avaliar o índice de proliferação celular. Diversas características histológicas foram observadas, como distribuição das células na pele, tamanho, forma, aspecto de citoplasma e núcleo, quantidade de estroma, presença de eosinófilos e alterações associadas. Com base nessas caracteríscas, 37,8% dos mastocitomas foram classificados como grau I, 51,1% como grau II e 11,1% como grau III. A média geral de AgNOR nos mastocitomas foi de 1,9 (1,2 a 4,3) e as médias para os graus I, II e III... |

| RESUMO Objetivou-se com este estudo avaliar o processo de cicatrização de feridas de coelhos tratadas com extrato de barbatimão (S. adstringens) associado a células mononucleares autólogas da medula óssea (CMMO). Utilizaram-se 20 coelhos, distribuídos em quatro grupos: B, extrato de barbatimão; CB, CMMO com extrato de barbatimão; CS, CMMO com solução fisiológica; S, solução fisiológica. Foi avaliada a presença de crosta, hiperemia, secreção, hemorragia, reepitelização, área da ferida e tempo de cicatrização. No terceiro, sétimo, 14º e 21º dias pós-operatório, realizou-se a biópsia das feridas e avaliaram-se os indicadores dos processos de inflamação e de reparo, com destaque para o colágeno, na coloração picrosírius, bem como de proliferação celular, na... |

| The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with conventional methods (Giemsa staining, silver staining of the nucleolus organizer regions-AgNOR, and C-banding) and fluorescence in situ hybridization (FISH) with 18S and 5S ribosomal DNA probes in five species of the Prochilodus genus (Prochilodus argenteus, Prochilodus brevis, Prochilodus costatus, Prochilodus lineatus and Prochilodus nigricans) collected from different Brazilian hydrographic basins. The results revealed conservatism in chromosome number, morphology, AgNORs 18S and 5S rDNAs location and constitutive heterochromatin... |
