Adrenal glands of Spix's yellow-toothed cavy (Galea spixii, Wagler, 1831): morphological and morphometric aspects.
Considering the physiological importance and need of greater morphophysiological knowledge of adrenal glands, the aims of present study were compare the morphometric data between left and right adrenal of male and female; perform a histological, scanning and transmission electron microscopy study showing tissue constitution of glands; finally, in order to define the presence and correct site of...
متن کاملUltrastructure of spermatogenesis in Spix's yellow-toothed cavy (Galea spixii).
This was a pioneer study of the spermatogenic process from the onset of puberty in Spix's yellow-toothed cavies (SYC, Galea spixii) bred in captivity. The study aimed to characterize fine structure of spermatogenesis. Twelve testes from pubertal and post-pubertal SYC males were studied using transmission electron microscopy. Spermatogenesis can be divided into three phases: proliferation, meios...
متن کاملChorioallantoic placentation in Galea spixii (Rodentia, Caviomorpha, Caviidae)
BACKGROUND Placentas of guinea pig-related rodents are appropriate animal models for human placentation because of their striking similarities to those of humans. To optimize the pool of potential models in this context, it is essential to identify the occurrence of characters in close relatives. METHODS In this study we first analyzed chorioallantoic placentation in the prea, Galea spixii, a...
متن کاملImmunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle
BACKGROUND The synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex with the redox partner NADPH-cytochrome P450 oxidoreductase (CPR) for activity. Previous studies have identified expression of steroidogenic enzy...
متن کاملExperimental infection parameters in Galea spixii (Rodentia: Caviidae) with Leishmania infantum chagasi.
In order to better understand the epidemiological transmission network of leishmaniasis, an endemic disease in Northeast Brazil, we investigated the susceptibility of Spix yellow-toothed cavies (Galea spixii) to the Leishmania infantum chagasi parasite. Nine cavies were experimentally infected, separated into three groups and monitored at 30, 90 and 180 days, respectively. Amastigotes were iden...
