PURPOSE To determine the structure and function of a system of large blood vessels integrated in the bony canal between the orbit and the inferior nasal duct. METHODS Thirty-one dissected lacrimal systems of adults were analyzed by using gross anatomy, histology, and electron microscopy as well as corrosion vascular casts. RESULTS More than two thirds(More)
The lacrimal sac and nasolacrimal duct are surrounded by a wide cavernous system of veins and arteries comparable to a cavernous body. The present study aimed to demonstrate the ultrastructure of the nervous tissue and the localisation of neuropeptides involved in the innervation of the cavernous body, a topic not previously investigated.

In 5 newborn infants with severe valvular aortic stenosis, left ventricular angiocardiography revealed conspicuous pathologic-morphologic findings consisting of a fine network of contrast medium opacification in the region of the posterior wall. Subsequently performed histologic examination of tissue removed from the involved regions showed, in addition to(More)
Colorectal surgery is still burdened by a comparatively high rate of anastomotic leakages. The benefits of different fibrin gluing techniques (fibrin adhesive Tissucol, also with collagen tissue; gentamicinincorporated collagen-fibrinogen lyophilisate) were studied in the rat colon. In the early postoperative course (up to 24h p.o.), the sutures that were(More)
Pathogenesis and morphology of postoperative intraperitoneal adhesions were studied experimentally in rats (n = 240). The number of adhesions after excision of the serosal layer shows a dynamic development with periods of growth and lysis. The intraperitoneal application of normal saline decreases the amount of adhesions during the first week; the(More)
