Aspectos toxicológico, clínico-patológico e ultraestrutural das intoxicações iatrogênica e experimental por vitamina D em coelhos

São descritos aspectos toxicológicos, clínico-patológicos e ultraestruturais de coelhos intoxicados iatrogênica e experimentalmente por vitamina D por via subcutânea. Clinicamente, os animais evidenciaram sinais de insuficiência cardiovascular como ascite e edema pulmonar, hiporexia, anorexia, diarréia mucosa, emagrecimento e apatia. As clássicas alterações de mineralização e, por vezes, osseificação, do sistema cardiovascular, bem como as alterações de rins, pulmões, estômago, entre outros órgãos, foram reproduzidas com administrações subcutâneas de solução oleosa de colecalciferol (vitamina D3 não-ativada).

Estimativa do surto de crescimento puberal pela avaliação das vértebras cervicais em radiografias cefalométricas laterais

The aim of this research was to estimate the skeletal growth and development by observingradiographically the morphological changes of the first, second and third cervical vertebrae, according to the method proposed by Hassel &Farman32 (1995) in patients who were going through the outbreak of pubertal growth. The radiographic inspection of the cervical vertebrae was performed by means of cephalometric radiographs and the outbreak of pubertal growth was identified through the events of ossification of the hand and wrist. For that purpose, we selected thecephalometric radiographs and hand•wrist radiographs of 110 Brazilianleukoderms, male and female,with chronological age ranging from 8 to 14,6 years old for the girls and from 9,5 to 15,4 years old for the boys.The results showed that there was a statistically significant correlation between the maturation indicators of the cervical vertebrae and the patients who were going through the outbreak of pubertal growth. The conclusion was that the radiographic evalution of the changes of the cervical vertebrae, in the cephalometric radiographs, is an alternative parameter, which is reliable and practical in the skeletal evalution, and the it completes the range of information that must be obtained from the patient under orthodontic treatment and that it can, circumstantially, replace other methods of evalution

Tomographic imaging of lunulae in capybara knees

The lunulae, ossification of the meniscus, are found in several species of rodents. Some studies suggest that the lunulae may be anatomical features, because there are not any pathological findings in microscopy. The objective of this study was to investigate the presence of lunulae in capybara knees, the world's largest rodent, by simple tomographic scans and three-dimensional reconstruction. For this purpose, we used two adult capybaras, in which both knees were evaluated. The lunulae were visualized with three-dimensional images, and revealed a total of two cranially. With the presence of lunulae confirmed, the capybara may be included in the group of rodents that have this structural feature, which can also contribute to the distinction between pathological processes and normal anatomic structures on imaging tests.

Diabete moderado induzido em diferentes fases da vida de ratas Wistar: repercussões na reprodução materna e na freqüência de anomalias fetais

Experimental models are necessary to elucidate pathophysiological mechanisms not yet understood in humans. To evaluate the repercussions of the diabetes, considering two methodologies, on the pregnancy of Wistar rats and on the development of their offspring. In the 1st induction, female offspring were distributed into two experimental groups: Group streptozotocin (STZ, n=67): received the β-cytotoxic agent (100mg STZ/kg body weight - sc) on the 1st day of the life; and Non-diabetic Group (ND, n=14): received the vehicle in a similar time period. In the adult life, the animals were mated. After a positive diagnosis of pregnancy (0), female rats from group STZ presenting with lower glycemia than 120 mg/dL received more 20 mg STZ/kg (ip) at day 7 of pregnancy (2nd induction). The female rats with glycemia higher than 120mg/dL were discarded because they reproduced results already found in the literature. In the mornings of days 0, 7, 14 and 21 of the pregnancy glycemia was determined. At day 21 of pregnancy (at term), the female rats were anesthetized and killed for maternal reproductive performance and fetal development analysis. The data were analyzed using Student-Newman-Keuls, Chi-square and Zero-inflated Poisson (ZIP) Tests (p<0.05). STZ rats presented with increased rates of pre (STZ=22.0%; ND=5.1%) and post-implantation losses (STZ=26.1%; ND=5.7%), reduced rates of fetuses with appropriate weight for gestational age (STZ=66%; ND=93%) and reduced degree of development (ossification sites). Conclusion: Mild diabetes led a negative impact on maternal reproductive performance and caused intrauterine growth restriction and impaired fetal development

Effect of essential oil from Citrus aurantium in maternal reproductive outcome and fetal anomaly frequency in rats

Citrus aurantium L., commonly known as bitter orange, is widely used in folk medicine, but there is little data in the literature about the s on pregnancy. The aim of the present study was to evaluate the influence of essential oil obtained from fruits of Citrus aurantium on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant Wistar rats were randomized into four groups (n minimum = 12 animals/group): G1 = control, G2 to G4 = treated with essential oil from C. aurantium at dose 125, 250 and 500 mg/kg, respectively. Rats were orally treated, by gavage, with plant essential oil or vehicle during pre-implantation and organogenic period (gestational day 0-14). On gestational day 20 the rats were anaesthetized and the gravid uterus was weighed with its contents and the fetuses were analyzed. Results showed that the treated group with 500 mg/kg presented decreased placental weights and placental index, although the treatment with bitter orange essential oil did not show any alteration in maternal reproductive performance, toxicological , changes in ossification sites, and malformation index. In conclusion, the treatment of Citrus aurantium essential oil was not teratogenic and did not alter the maternal reproductive outcome.
