Analysis of Fetal and Placental Development in Rats after Administration of Hydroalcoholic Extract from the Root of Petiveria alliacea L. (Phytolaccaceae) International Journal of Morphology
Maia,Carina Scanoni; Teixeira,Valéria Wanderley; Teixeira,Álvaro Aguiar Coelho; Pontes Filho,Nicodemos Teles.
We investigated the effect of hydroalcoholic extract the Petiveria alliacea root on fetal and placental development female rats pregnancy. Thirty female rats were mated and divided in groups: I - rats treated with placebo and sacrificed on the 7th day; II - rats treated with hydroalcoholic extract and sacrificed on the 7th day; III - rats treated with placebo and sacrificed on the 14th day; IV - rats treated with hydroalcoholic extract and sacrificed on the 14th day; V - rats treated with placebo for analysis of the offspring; VI - rats treated with hydroalcoholic extract for analysis of the offspring. The extract was administered by gavage in the dosage of 18mg/kg body wt., in 5th day of pregnancy. The implantation sites and placenta were fixed in Bouin...

Effect of the Treatment with Dexamethasone, for 10 and 15 Days, on the Fertility in Induced Rats to Polycystic Ovaries, by Constant Illumination International Journal of Morphology
Moraes,Eleonora de Figueiredo; Wanderley Teixeira,Valéria; Teixeira,Álvaro Aguiar Coelho; Silva,Welma Emídio da; Batista,Ana Paula Castor; Lemos,Ana Janaína Jeanine Martins de.
The present study had the objective of obtaining information about fertility in rats treated with dexamethasone for 10 and 15 days consecutively, to polycystic ovaries, induced by constant illumination. It was used 40 albino rats (Rattus norvegicus albinus), aged 90 days, form the lineage Wistar, which were split, randomly, in four groups, each constituted of 10 animals, namely: Group I - rats kept in a clear/dark cycle for 12/12 hours, and after 100 days submitted to fertility evaluation (control); Group II - rats kept under constant illumination during 100 days and then submitted to fertility evaluation; Group III - rats kept under constant illumination during 100 days, then treated with dexamethasone for 10 days and submitted to fertility evaluation;...

Evaluation of the Estral Cycle in Rats after Treatmen twith Dexamethasone for Polycystic Ovaries, Induced by Constant Illumination International Journal of Morphology
Barros,Heitor Arôxa; Moraes,Eleonora Figueredo de; Maia,Carina Scanoni; Teixeira,Álvaro Aguiar Coelho; Teixeira,ValériaWanderley.
The study aimed at obtaining basic information about estrous cycle in rats treated with dexamethasone, for polycystic ovaries, induced by constant illumination. It was used 30 female rats (Rattus norvegicus albinus) from the lineage Wistar, with 90 days years old, divided according the following groups: Group I - rats maintained in a light/dark cycle for 12/12 hours, and after 100 days submitted to the cyclicity evaluation (control); Group II - rats maintained under constant illumination during 100 days and after submitted to the cyclicity evaluation; Group III - rats maintained under constant illumination during 100 days and after treated with dexamethasone for five days, and, then, submitted to the cyclicity evaluation. The results showed that after 100...

Histological Evaluation of the Induced Endometriosis in Rats, after Treatment with Dexamethasone International Journal of Morphology
Batista,Ana Paula Castor; Conceição,Ana Paula Maria da; Moraes,Eleonora de Figueiredo; Teixeira,Álvaro Aguiar Coelho; Wanderley Teixeira,Valéria.
The present research had the purpose to analyze morphologically the sites of endometrial implants on the external area of the musculature of the anterior abdominal wall of female rats, treated with dexamethasone. For so, these 15 albino female rats were used (Rattus norvegicus albinus), of the lineage Wistar with 90 days of age, that were submitted to the induction of the endometriosis, and divided in the following groups: Group I ­ induced female rats to endometriosis and evaluated after 21 days (control); Group II ­ induced female rats to endometriosis and after 21 days, treated with dexamethasone for 10 days; Group III - induced female rats to endometriosis, and after 21 days, treated with dexamethasone for 15 days. The dexamethasone was administered in...

Histopathology of Organs from Neonate Offspring Born to Female Rats Exposed to Sublethal Doses of Biological and Synthetic Insecticides International Journal of Morphology
dos Santos,Hilda Michelly Paiva; Teixeira,Valéria Wanderley; Teixeira,Álvaro Aguiar Coelho; da Silva,Rosimere; Lemos,Ana Janaina Jeanine Martins; Neto,Clovis José Cavalcanti Lapa; Ferreira,Cintia Giselle Martins.
The current annual consumption of insecticides in agriculture in Brazil is over three million tons. The exposure happens through food that is contaminated with toxic waste and respiratory and dermal absorption. Biological control with Bacillus thuringiensis Berliner (Bt) has assumed increasing importance replacing the use of conventional insecticides. However, the tests used to justify approval for use and market release of Bt products, and the protocols used to assess the development of toxicity, are extremely superficial. In addition, more studies comparing effects between males and females and during pregnancy and lactation have not been conducted. Thus, the hypothesis tested in this study was if the administration of the XenTari® WG (Bacillus...

Ultrastructure of the antennal sensilla of Alabama argillacea (Hübner, 1823) (Lepidoptera: Erebidae) Rev. Bras. entomol.
Santos,Andrezo Adenilton; Wanderley-Teixeira,Valéria; Cruz,Glaucilane dos Santos; Navarro,Daniela Maria do Amaral Ferraz; Alves,Luiz Carlos; Brayner,Fábio André; Teixeira,Álvaro Aguiar Coelho.
Abstract Insects have several types of sensilla, the characterization of which has been fundamental to understanding the mechanisms of sensory perception in different species. This study aimed to describe the ultrastructure of the sensilla present on the antennae of Alabama argillacea (Hübner, 1823) (Lepidoptera: Erebidae), an important pest of cotton (Gossypium hirsutum L.) crops, as well as their possible variation between sexes. To do this, the antennae of males and females of A. argillacea were analyzed using scanning electron microscopy. Sensilla morphometry was assessed using photomicrographs, from which the lengths and basal and apical diameters of sensilla were measured using the ImageJ program. Seven types of sensilla were identified on the...
