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

PURPOSE: To report the results of managing dislocated posterior chamber intraocular lenses (PC IOLs) by externalizing the haptics through a clear corneal incision. SETTING: The Retina Center at Pali Momi, Aiea, Hawaii, USA. METHODS: This retrospective consecutive series comprised cases in which a dislocated PC IOL was managed with pars plana vitrectomy. With this method, the dislocated PC IOL is retrieved and stabilized in the anterior chamber. The haptic is externalized through a clear corneal incision for suture knot placement and then reinserted. A scleral fixation suture is placed 1.25 mm posterior to the limbus under a scleral flap. RESULTS: The study included 14 eyes of 14 patients with a minimum follow-up of 6 months (median 15.4 months). There were 2 subluxated PC IOLs, 11 posteriorly dislocated PC IOLs, and 1 in-the-bag IOL dislocation. Postoperative vision and/or visual symptoms were stable or improved in 86% of eyes. Two eyes had worse vision caused by conditions not related to surgery including chronic cystoid macular edema from latanoprost use and optic atrophy. All IOLs were well fixated and stable, although 1 eye with asymmetric haptics had a slightly tilted IOL. CONCLUSIONS: Dislocated PC IOL management by externalizing the haptic through a clear corneal incision stabilized the IOL in the anterior chamber, minimized intraocular operative manipulations, and allowed easier placement of the opposite haptic over residual capsule, if available. Stable fixation was achieved without dislocation or IOL-related complications recurring. 相似文献

胃癌癌前病变癌变机制及其逆转的研究进展 总被引:23,自引:7,他引:16
王冠庭 《世界华人消化杂志》2000,8(1):1-4
胃癌癌前病变与胃癌的发生关系,日益受到重视,近几年来特别强调幽门螺杆菌为引起慢性萎缩性胃炎与胃癌的重要危险因子.因此,许多学者进一步深入研究幽门螺杆菌感染对发生胃癌的危险性,胃癌癌前病变发生癌变的机制以及如何使其逆转,是预防和降低胃癌发病的重要课题. 相似文献
