Estudo comparativo da área ocupada pelos corpos pedunculados no cérebro de duas espécies de abelhas (Hymenoptera, Apoidea)

The present study compare the size of the corpora pedunculata (mushroom bodies) of Exomalopsis aureopilosa a quasi-social specie and Apis mellifera a eusocial specie of bees. The aim was to correlate the developmental degree of such structures with the behavior complexity. The results show that the female specimens of both species have the corpora pedunculata with same relative size. However the area occupied by the neurones cellular bodies (glomeruli) is greater in the workers of A. mellifera. In other way in E. aureopilosa the total size of the corpora pedunculata is larger in females, but the glomeruli area is relatively larger in the male.

Predação de morcegos (Phyllostomidae) pela cuíca d’água Chironectes minimus (Zimmermann, 1780) (Didelphimorphia, Didelphidae) e uma breve revisão de predação em Chiroptera

Bats are predated for some of vertebrates and invertebrates. Some opportunistic species preys these animals' prisoners in nests during procedures of capture in field. This study records the predation of Carollia perspicillata (Linnaeus, 1758) and Sturnira lilium (E. Geoffroy, 1810) for Chironectes minimus (Zimmermann, 1780) on riparian forest of the brook Talhadinho belonging of the São Paulo, São Paulo, Southeast Brazil, and also presents a lifting previous of mammalian what they present the same one behavior opportunistic predatory, discussing measures simple to avoid this type of predation.

Obstrução intestinal e enterotomia em tigre d’água (Trachemys dorbignyi)

Intestinal obstruction occurs in chelonian mainly due parasitism and foreign bodies, as stones and sand. An intestinal compaction was described in a five year-old male d'orbigny's slider which was taken to the Veterinary Medical Teaching Hospital of the UNICASTELO, at Fernandopolis, SP, Brazil, presenting anorexia for a week, severe dehydration and stupor. Definitive diagnostic was performed by radiographic exam and great amount of intestinal radiopac substance was detected. The animal went through emergency celiotomy for removing the intestinal foreign bodies. Inhalatory anesthesia with isofluorane was used for anesthesia induction and manutention. After local antisepsy, a 4cm(2) oblique opening was conducted on plastron by using a vibratory saw. Peritoneum was cut, intestines exteriorized and enterotomy performed. During the surgery, the animal was radiographed to confirm the complete taken out of the foreign bodies. Mononylon 4-0 strand was applied for intestinal suture in two planes. The plastron piece that was taken out was replaced and set with epoxy resine and gaze on the surgical window, making it waterproof. In the postoperative time, animal was medicated with analgesics for two days and pentabiotics for five days. Oral creamy diet was used with oral tube from the second to tenth day, what provided a great clinicosurgical recovering.

Lipoperoxidação, perda de viabilidade celular e diminuição da liberação de IL-8 de neutrófilos humanos na presença de corpos cetônicos

Type-1 diabetes patients suffer from frequent episodes of acidosis caused by an increased fatty acid metabolism and consequently increased plasma level of acetoacetate (AcAc) and β-hydroxybutyrate (β-HOB). This article describes a study of the effects of pathological concentrations of AcAc and β-HOB on lipoperoxidation, cell viability and the release of the CXCL8 (IL-8) cytokine by activated neutrophils. Neutrophils from healthy donors were isolated by density gradient (Histopaque® 1077/1119) and incubated with the ketone bodies. Lipoperoxidation was determined as thiobarbituric acid reactive substances (TBARS). The cell viability was evaluated by the release of intracellular lactate dehydrogenase. The release of CXCL8 was measured by ELISA in a 24-h culture of opsonized zymosan-stimulated neutrophils. AcAc, but not β-HOB, provoked a dose-dependent increase in the neutrophil membrane lipoperoxidation (p<0.05; r =0.9915). In the cytotoxicity assay, a dose-dependent release of LDH was observed when the neutrophils were incubated with AcAc in concentrations up to 40 mM (p<0.05). β-HOB was devoid of effect. The release of CXCL8 was inhibited by AcAc and β-HOB in a dose-dependent manner. In conclusion, these results suggest that the accumulation of ketone bodies in diabetic patients could be involved in their usually increased susceptibility to infection.
