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

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.

Reproductive losses in the southern region of Brazil have been a major problem for sheep farmers and studies in the area report that the weight of lambs at birth when greater than 4Kg allows it to survive during the winter period in which they are born. Due to the need for greater weight at birth, to ensure greater survival, numerous procedures have been performed in an attempt to promote lower mortality. The purpose of this work was to verify the influence of shearing on transplacental glycogen transport and its supposed relationship with the increase in birth weight in lambs (Ovies aries). For the realization of the project 9 sheep of the Australian Merino breed were used which were raised at the Federal University of Rio Grande do Sul - Porto Alegre / RS) - UFRGS in collaboration with the Lutheran Brazilian University - ULBRA. The animals were divided into 2 groups: the first with 5 sheared animals (OVE) at 70 days of the perinatal period and the second with four animals that were kept as control (OVC). The fetuses were collected through a surgical cesarean section performed at the end of pregnancy. For comparative purposes, placental and fetal weight were initially measured; to characterize the placenta, the number of placentons and the length, width and thickness of the placentonium were quantified, with the aid of a caliper. The collected placental material was fixed, dehydrated, diaphanized and included in paraffin, for later making slides and quantifying glycogen. As a partial macroscopic result, the placentas of the sheep in the sheared group had a weight 13% greater than those in the control group, in the fetuses the difference was more expressive, the weight of the fetuses sampled in the sheared group was 25% greater than those in the second group. The differences between the measures of thickness, length and width were insignificant, but always with higher rates in the tested group.
