Abstract: Human leukocyte-derived lipoxin A (LXA; 5S,-6R,15S-trihydroxy-7,9,13-trans-11-cis-eicosatetraenoic acid) inhibits the cytotoxic activity of human natural killer (NK) cells. LXA and three of its isomers were prepared by total organic synthesis and assayed for activity with human NK cells. Dose-response studies showed that biologically derived LXA and synthetic LXA were equally effective in inhibiting NK cell cytotoxicity. 6S-LXA, with its 6S-OH group in an (S) configuration, proved to be approximately half as potent as LXA. In contrast, 6S-11-trans-LXA and 11-trans-LXA displayed virtually no inhibitory activities. The methyl esters of both LXA and 6S-LXA proved to be more potent than their corresponding free acids. Thus, LXA inhibition of NK cells displays clear-cut stereochemistry. In the absence of putative inhibitors, NK cells bind to their targets to form conjugates. This event is followed by polarization of the NK Golgi apparatus, which moves towards the plasma membrane that is in contact with the target cell. However, in the presence of either the methyl ester or free acid of LXA, the Golgi apparati of NK cells bound to their targets were randomly oriented. In contrast, neither 6S-11-trans-LXA nor the potent NK inhibitor prostaglandin E2 affected the polarization. Furthermore, although prostaglandin E2 resulted in a decrease in NK-target cell binding efficiency, LXA and its isomers failed to affect conjugate formation. Together these results indicate that LXA-induced inhibition of NK cytotoxicity does not act on NK cell binding but may block cytotoxicity by disrupting "signals" involved in the specific orientation of the Golgi. Thus, this latter event may appear to be important in cytotoxicity.

Abstract: For the treatment of familial hypercholesterolemia, Liposorber LA-40 was clinically applied. The Liposorber is a commercially developed affinity adsorbent for plasma perfusion which selectivity adsorbs low density lipoproteins and very low density lipoproteins and is specially designed for plasmapheretic treatment of hypercholesterolemia. The Liposorber column, containing activated cellulose beads having an affinity for lipoprotein containing apolipoprotein-B, has an excellent adsorption capacity, excellent selectivity, minimum albumin loss. This new apheresis system was applied to 2 clinical cases. After seven months of trial perfusion every 2 weeks, patient condition was good, with a level of total cholesterol under 300 mg/dl. No replacement fluids were given during or after treatment. In this paper, clinical results of these patients were shown and the mechanism of adsorption of this specific adsorbent was discussed.

Abstract: This article describes the immunologic and pulmonary abnormalities and the chemical composition of pleural effusion fluid in a patient with intestinal lymphangiectasia as they are effected by therapeutic measures during a 7-year period. Lymphedema was first noticed in the patient at 3 years of age, and pleural effusions developed 7 years later. Thoracentesis demonstrated that the right pleural fluid was yellow, clear, and had the composition of lymph. The left pleural fluid was milky and had a higher triglyceride and lymphocyte content than the right pleural fluid. Complete removal of pleural fluid transiently increased total lung capacity to a maximum of 52% predicted. Strict dietary management with a low-fat and high-protein diet resulted in a transient partial reversal of circulating lymphopenia and low T cell concentration. This was accompanied by a decrease in lymphocyte and T cell concentration in the pleural fluid. Unstimulated mononuclear cells from pleural fluid synthesized increased amounts of DNA, and added mitogens or antigens further increased DNA synthesis. Dietary therapy had a minimal effect on this DNA synthesis. Despite circulating hypogammaglobulinemia, normal antibody activity was detected. The proportion of B cells in pleural fluid was greater than that in the circulation, and dietary therapy did not alter this difference. Pulmonary physiology improved during the initial 9-month period of diet therapy, but then the rate of fluid accumulation increased, causing respiratory compromise. Stability was achieved by a right-sided pleurodesis, followed 18 months later by a left pleurodesis with the addition of a shunt to provide internal lymph drainage.
