| Estudou-se a ocorrência de apoptose nos placentomos de cabras gestantes intoxicadas experimentalmente com o cipó-preto (Tetrapterys multiglandulosa A.Juss.). Analisou-se morfometricamente a intensidade do processo de apoptose nas células trofoblásticas em cabras controle (grupo III) e em animais submetidos a diferentes dosagens (grupos I e II) de cipó-preto. O grupo I foi composto por quatro cabras gestantes que receberam 10gramas/kg de peso vivo de folhas verdes da referida planta. No grupo II, quatro cabras gestantes receberam 20 gramas/kg de peso vivo de folhas verdes. A quantificação morfométrica da apoptose demonstrou que nas cabras tratadas a apoptose ocorreu com maior intensidade quando comparada com a obtida em animais do grupo-controle. Diferentes... |

| 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... |

| The thymic morphometry analysis was used for determining apoptosis and atrophy of the thymus of eight puppies inoculated with canine distemper virus (CDV). Three healthy dogs were used as negative controls. Sections, 5µm thick, were stained by HE and Shorr, and the latter were evaluated by morphometry. CDV nucleoprotein was detected by immunohistochemistry. Morphometric results confirmed lymphoid hypotrophy in CDV inoculated dog thymuses, more stroma, less parenchyma and higher apoptotic index/field than negative control (not inoculated) puppies. Apoptosis plays a role in the mechanism of thymus atrophy that develops in canine distemper. |
