    Rodents comprise most of the mammalian class. There are currently 2,021 species, organized into 443 genera and 29 families. Hedgehogs (Coendou villosus), are animals that in captivity, reproduce with some ease and become tame. In the urban and metropolitan region their presence is becoming common and this can be identified by the number of accidents involving dogs in the yard, registered in veterinary clinics. This work aimed to describe macroscopically the reproductive apparatus of Coendou villosus (hedgehog) to better clarify the anatomy of this important organ in the wild rodent model, since very little is known about this species. We compared the results obtained with other rodent species already studied. For the macroscopic description of the male reproductive system, 2 animals from donations were used, these animals ended up dying after attack by dogs.

    Estudo histológico da glândula pineal de Nasua nasua (Quati) empregando microscopia de luz
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2007-11-30) FAVARON, Phelipe Oliveira; MANÇANARES, Celina Almeida Furlanetto; AMBRÓSIO, Carlos Eduardo; CASALS, Juliana Barbosa; MIGLINO, Maria Angélica; CARVALHO, Ana Flávia de
    Nasua nasua or coati is a mammal of the carnivorous order and Procyonidae family. They are animals that live in flocks and have a wide geographical distribution throughout South America. The pineal gland is an endocrine gland, whose melatonin synthesis is influenced by the light and dark periods of the day. The objective of this work was to describe the histology of the coati pineal gland, evaluating its arrangement and cellular composition. For this work, 5 pineal glands were used, which were processed according to routine tissue processing techniques and then a paraffin was included. The pineal gland microscopically has a shape similar to a small pine cone and is divided into 3 parts: apex, body and base. The predominant cells in the glandular parenchyma were pinealocytes, which have large, rounded nuclei with little apparent cytoplasm. Externally the coati pineal gland is lined by a connective tissue capsule from which septa depart into the gland. Secretions were observed at the glandular apex.
