[Classical Kaposi's sarcoma. Study of the lymphatic system of lower limbs].

Eight patients with classical Kaposi's sarcoma histologically confirmed underwent lymphoscopic and/or lymphographic exploration of the lower limbs where the lesions were located. In all patients lymphoscopy showed abnormal images ranging from irregular distribution of the colouring agent to "starlike images" and dermal reflux. Lymphography was performed in 3 patients and demonstrated, in 2 of them, "lymphatic pools", obvious hyperplasia of the superficial lymphatic vessels and areas of lymphangectasia. The finding in all 8 patients of dynamic abnormalities of the lymphatic system should encourage further investigations in this field, notably to detect a possible correlation between lymph stasis, disorders in regional immunity and the development of classical Kaposi's sarcoma.

Computed tomography of the cranio-cervical lymphatic system: anatomical and functional considerations.

As an initial route of the spread of inflammatory and neoplastic pathology, the complex lymphatic system of the cervical region assumes an important part of the examination in patients with extra-axial disease of the head and neck. In addition, the often overlooked cranio-facial lymphatics must also be routinely investigated in order to forward the understanding and sensitivity of the neuroradiologic evaluation of primary sites of disease propagation from these areas.

Significant changes in intestinal lymphatic system and immune response elicited by Peyer's patch excision in adult rats.

The effect of deprivation of Peyer's patches (PP) on transport of lymphocytes through intestinal lymph and intestinal mucosal immune responses was investigated in rats. All visible PP in the rat small intestine were excised in order to examine the roles of PP in the intestinal lymphatic system and mucosal immune responses of the intestine. Two weeks after the experimental excision of PP, lymphocyte transport in intestinal lymph was significantly decreased in PP-excised rats without significant changes in lymphocyte subsets as compared with sham operated control rats. Lymphocyte subsets as determined morphometrically in the intestinal mucosa showed no significant alteration in PP-excised rats. There was a significant decrease in the number of immunoglobulin A (IgA) containing cells in the intestinal mucosa of PP-excised rats, while IgM and IgG containing cells showed no statistically significant changes in number. Conversely, the macrophages in the intestinal mucosa increased in number, suggesting the enhanced accessory functions of these macrophages. Antigen-specific immune response was further studied in PP-excised rats using intraduodenal priming and challenge with cholera toxin (CT). Both the determinations of cells producing antigen-specific antibody in the intestinal mucosa using anti-CT antibody and those of cells secreting anti-CT Ig in the intestinal lymph by enzyme-linked immunospot (ELISPOT) assay showed a significant reduction of CT-specific antibody production in PP-excised rats compared with controls. Peyer's patches appear to have an important role in lymphocyte transportation through intestinal lymph and also in mucosal immune responses.

Distribution and fine structure of the lymphatic system in the human testis.

The distribution of lymph vessels in the human testis was investigated using ink injection methods, and light and electron microscopy. Lymph capillaries occur in the septula testis but are absent in the intertubular tissue. They consist of endothelial cells provided with an incomplete basal lamina and anchoring filaments of the adjacent connective tissue. Frequently, the endothelial cells are separated by gaps measuring up to 2 micron. The lymph capillaries of the septula testis are connected to lymph vessels in the rete testis and tunica albuginea. These vessels have occasional smooth muscle cells and valves. At the posterior margin of the testis, the network of lymph vessels merges into collecting ducts, which together with vessels derived from the rete testis are drained by the lymphatic system in the spermatic cord.

[Effects of vagotomy on the lymphatic system of the small intestine].

Vagotomy in experiments induces compensatory dilatation of the lymph vessels of the small intestine, which is directed at correction of the microcirculatory shifts encountered in the postoperative period in the form of venous stasis and edema of the wall of the small intestine. Vagotomy leads to slowing down and terminal shift of digestion and exclusion of the duodenal lymph vessels from the process of absorption and transportation of fat. The restoration of the morphology and function of the lymph vessels in the late postoperative period is determined by the type of vagotomy. Microcirculation and the state of the lymphatic system improve more rapidly and fully after selective proximal vagotomy.

[Lymphatic system changes after the endolymphatic administration of an oil-based solution of dibunol].

Endolymphatic infusions of a 10 percent solution of dibunol in iodolipol or chromolymphotrast were given for prevention of lymphogenic dissemination of rectal cancer. Certain changes in X-ray pattern of lymphogenic metastases developed due to prolonged intravascular retention of the contrast agent. Under such conditions metastatic lesions took the form of collateral lymph flow development and enlargement and deformation of lymph nodes. The diagnostic value of lymphography appears to be still higher when several symptoms of metastatic involvement of the lymphatic system are in evidence.
