Further study on the vascular basis for the reimplantation of the hand amputated through the palm 总被引:1,自引:0,他引:1
Summary Based on the anatomic data obtained from earlier studies on the vascular anatomy of the hand, the vascular architecture in the palm of the hand was studied on 60 sides of unembalmed adult upper extremities. Each palm was divided into 64 squares by 8 sagittal and 8 transverse sections. The vascular architecture in these squares and the arterial relations between them were observed and measured by angiography, operative microscopic dissection and computerised three-dimensional reconstruction. According to the pattern of the blood-vessels, the amputated palms can be classified into 4 types. The anatomic basis for the vascular anastomosis in each type is defined. There are three key-areas for the blood-supply of the palm and their significance is discussed. Apart from the 4 types of transversely amputated palms, the repair programe of the blood-vessles in 4 types of common obliquely amputated palms are also discussed.
Etude complémentaire de l'anatomie vasculaire de la main pour la réimplantation des amputations transpalmaires
Résumé Sur la base de données anatomiques obtenues lors de précédents travaux sur l'anatomie vasculaire de la main, l'architecture vasculaire palmaire a été étudiée sur 60 extrémités supérieures de cadavres d'adultes, non embaumés. Chaque paume a été divisée en 64 carrés par 8 sections sagittales et 8 sections transversales. L'architecture vasculaire à l'intérieur des carrés et les relations artérielles entre eux ont été étudiées et mesurées par angiographie, dissection au microscope opérateur et reconstruction computérisée en 3D. Les paumes amputées ont été regroupées en 4 types d'après la distribution des vaisseaux sanguins. Les données anatomiques concernant les anastomoses vasculaires sont précisées. Il existe trois zones clés pour l'irrigation de la paume. Leur importance quant à l'irrigation de la main est exposée. Outre la division des paumes amputées transversalement en 4 types, le programme de réparation de vaisseaux dans les 4 types d'amputations obliques communes de la paume et aussi discuté.相似文献

In this study, Tithonia diversifolia Helms. (A Gray), Aloe secundiflora (Miller) and Azadirachta indica (A. Juss) plant extracts were used to make herbal soaps while Thevetia peruviana (Schum) seed oil was used to make a herbal lotion for skincare. The soaps were tested for the growth inhibition of Escherichia coli, and Candida albicans. The lotion was evaluated against Staphylococcus aureus and E.coli. Although Tithonia diversifolia soap exhibited the highest inhibitory effect on the test bacterial strains, it had the least inhibition against C. albicans. Results from this study indicated that the ‘Tithonia diversifolia’ soap would have superior skin protection against the tested bacteria but would offer the least skin protection against C. albicans. The herbal lotion inhibited S. aureus and E. coli in a concentration dependent manner, however, the inhibitory effect was more pronounced on S. aureus. 相似文献

The Joro spider toxin (JSTX-3), derived from Nephila clavata, has been found to block glutamate excitatory activity. Epilepsy has been studied in vitro, mostly on rat hippocampus, through brain slices techniques. The aim of this study is to verify the effect of the JSTX-3 on the epileptiform activity induced by magnesium-free medium in rat CA1 hippocampal neurons. Experiments were performed on hippocampus slices of control and pilocarpine-treated Wistar rats, prepared and maintained in vitro. Epileptiform activity was induced through omission of magnesium from the artificial cerebrospinal fluid (0-Mg2+ ACSF) superfusate and iontophoretic application of N-methyl-D-aspartate (NMDA). Intracellular recordings were obtained from CA1 pyramidal neurons both of control and epileptic rats. Passive membrane properties were analyzed before and after perfusion with the 0-Mg2+ ACSF and the application of toxin JSTX-3. During the ictal-like activity, the toxin JSTX-3 was applied by pressure ejection, abolishing this activity. This effect was completely reversed during the washout period when the slices were formerly perfused with artificial cerebrospinal fluid (ACSF) and again with 0-Mg2+ ACSF. Our results suggest that the toxin JSTX-3 is a potent blocker of induced epileptiform activity. 相似文献
