Closure of large wounds using rubber bands in rabbits

OBJECTIVE: to verify the effectiveness of the rubber elastic band in the treatment of large wounds of the body wall of rabbits by means of traction of its edges. METHODS: we studied 30 New Zealand rabbits, divided into three groups (n=10): Group 1- healing by secondary intention; Group 2- removal and eutopic repositioning of skin as full thickness skin graft; Group 3- Approximation of wound edges with elastic rubber band. In all animals, we removed a segment of the back skin and subcutaneous tissue down to the fascia, in accordance with an acrylic mold of 8cm long by 12cm wide. All animals were observed for 21 days. RESULTS: two animals of groups 1 and 2 had wound abscess. In Group 2, there was partial or total graft loss in 90% of animals. The complete closure of the wounds was observed in four animals of Group 1, six of Group 2 and eight of Group 3. There was no difference between the scar resistance values of groups 2 and 3, which were higher than those in Group 1. The scars of the three groups were characterized by the presence of mature connective tissue mixed with blood vessels and inflammatory infiltration, predominantly polymorphonuclear. CONCLUSION: the tensile strength of the wound edges with rubber elastic band is as efficient as the skin graft to treat rabbits' large body wounds.

Efeito anticoccidiano de extrato hidroalcoólico de Artemisia annua em camas de aves contaminadas com Eimeria sp

Resumo O objetivo deste estudo foi avaliar a eficácia do extrato hidroalcoólico de Artemisia annua frente a oocistos de Eimeria sp. em camas contaminadas. O extrato foi produzido com 7 dias de percolação a 4°C, sendo posteriormente realizada a marcha fitoquímica; dosagem de fenóis totais, quantificação de artemisinina, ensaio antioxidante e teste de toxicidade. Para testar a atividade anticoccidiana, camas de aves compostas de cepilho de árvores foram contaminadas com 5000 oocistos. Foram formados quatro tratamentos, em triplicata, nos quais foram usadas diferentes concentrações, sendo G1: 12mg/mL, G2: 8mg/mL, G3: 4mg/mL e C-: água. Após a contaminação, foram aspergidos, 800 mL dos extratos nas diferentes concentrações sobre as camas e coletadas, em triplicatas, 10 cm2 de cada local, aleatoriamente, nos tempos: 0, 3, 6, 24, 48, e 72 horas após a aplicação. Nas análises fitoquímicas, foram evidenciados diversos compostos com propriedades antiparasitárias, como flavonoides e taninos. O fitoterápico continha 59,409±1,47μg/dL de artemisinina. O produto na concentração de 12mg.mL-1 apresentou eficácia entre 45,5 e 42,1%. Os resultados dos testes bioquímicos, juntamente com os encontrados no teste anticoccidiano, evidenciaram que o extrato produzido possui alto potencial para combater Eimeria sp.

Semi-automatic measurement of visual verticality perception in humans reveals a new category of visual field dependency

Previous assessment of verticality by means of rod and rod and frame tests indicated that human subjects can be more (field dependent) or less (field independent) influenced by a frame placed around a tilted rod. In the present study we propose a new approach to these tests. The judgment of visual verticality (rod test) was evaluated in 50 young subjects (28 males, ranging in age from 20 to 27 years) by randomly projecting a luminous rod tilted between -18 and +18° (negative values indicating left tilts) onto a tangent screen. In the rod and frame test the rod was displayed within a luminous fixed frame tilted at +18 or -18°. Subjects were instructed to verbally indicate the rod’s inclination direction (forced choice). Visual dependency was estimated by means of a Visual Index calculated from rod and rod and frame test values. Based on this index, volunteers were classified as field dependent, intermediate and field independent. A fourth category was created within the field-independent subjects for whom the amount of correct guesses in the rod and frame test exceeded that of the rod test, thus indicating improved performance when a surrounding frame was present. In conclusion, the combined use of subjective visual vertical and the rod and frame test provides a specific and reliable form of evaluation of verticality in healthy subjects and might be of use to probe changes in brain function after central or peripheral lesions.
