Abstract
Abstract
IL-8 is a chemotactic cytokine with proinflammatory and growth-promoting activities. Recently it has been shown to influence several functions of keratinocytes, including HLA-DR expression, chemotaxis, and proliferation by binding to a specific receptor. Because psoriasis vulgaris is characterized by epidermal hyperproliferation and infiltration of inflammatory cells, we investigated the expression of IL-8 and its receptor in normal and psoriatic epidermis using semiquantitative reverse-transcriptase-polymerase chain reaction. In addition the mRNA levels of the proto-oncogenes c-ras, c-raf, c-myc, and HER-2 were also investigated as potential growth-promoting stimuli in psoriatic epidermis. IL-8 mRNA was only detected in lesional psoriatic epidermis, and IL-8R-specific mRNA was found to be 10 times increased in lesional psoriatic epidermis. There was no significant difference in the protooncogene mRNA levels. In order to test the relevance of the massively increased IL-8R levels in psoriatic epidermis, we investigated the effect of the antipsoriatic drug FK-506 on specific IL-8 and IL-8R mRNA expression. FK-506 dose dependently inhibited IL-8R expression and function. Our data suggest that in psoriatic skin, elevated IL-8 levels and markedly increased IL-8R expression may act in concert to induce the cardinal signs of psoriasis--epidermal hyperproliferation and leukocyte infiltration. IL-8R may prove a molecular target for antipsoriatic drugs such as FK-506.

Abstract
Polymorphonuclear leukocyte (PMNL) infiltration is an important characteristic in psoriatic lesions. The proinflammatory 8-kD peptide interleukin-8 (IL-8) is present in psoriatic scales and possesses a high chemotactic activity on human neutrophils, which may relate to its role in psoriasis. Its chemotactic activity is mediated via specific receptors on PMNL. The goal of our work was to ascertain whether PMNL infiltration in psoriasis can be accounted for by functional abnormalities of the circulating PMNL due to alterations in the IL-8 receptor density or affinity (or both). Results of radioligand binding studies performed in 10 psoriatic patients, 10 patients with atopic eczema and 11 normal controls showed no difference in receptor affinity (Kd) between the groups. However, a slight but significant elevation in IL-8 receptor density was seen on PMNL from psoriatic individuals (31,230 +/- 3,237 binding sites per cell) compared to those from normal volunteers (24,152 +/- 2,643) and atopic eczema patients (24,092 +/- 2,743). Increased number of IL-8 receptors may, besides elevated cutaneous IL-8 concentrations, contribute to the intraepidermal accumulation of PMNL in psoriasis.

Abstract
The concentration of protein in the cerebrum of sheep after a period of feed restriction (group 2) was lower (94.5 +/- 10.2) than in normally fed sheep of group 4 (101.4 +/- 9.4 mg/g wet weight). In the group 2 the concentration of protein in the M. longissimus dorsi and in the M. semimembranosus was also smaller. A high DNA-concentration was determined in the intestinal lymph nodes, in the spleen and in the lung. The DNA-concentration of the testes of group 2 (7.17 +/- 2.92) was higher than that of the group 4 (4.46 +/- 1.70 mg/g w. w.), also that of the renal fat tissue (0.39 +/- 0.18 resp. 0.20 +/- 0.09). The highest protein: DNA-relation in group 4 was found in the fat tissue (203.5: 1) and the lowest in the spleen (15.3: 1). A high RNA-concentration was analysed in the lymph nodes, in the spleen and in the lung. The RNA-concentration in the fat tissue of group 2 (0.34 +/- 0.13) was higher that that in group 4 (0.15 +/- 0.08 mg/g w. w.).

Abstract
In lambs after weaning with a body weight of 16.3 +/- 1.5 kg (group 1) and in sheep after a period of fattening with an increase of the body weight of 72.2 +/- 13.6 (group 2), of 184.4 +/- 12.2 (group 3) respectively of 302.1 +/- 24.3 g per day (group 4) the concentration of the components mentioned in the title was analysed in blood and plasma. The hematocrit, the concentration of Hb in the blood and that of total protein, of nonprotein-N, of Na, of Ca, of the iron-binding capacity and of Zn as well as the activity of the 5 enzymes in the plasma of the sheep of group 4 were higher than that of the group 2. Stress by the transport and stunning increased the concentration of free fatty acids in the plasma. The significance of the results for the clinical-chemical diagnosis is discussed.

Abstract
We recently detected specific high-affinity binding sites for 12(S)-HETE, the main arachidonic acid metabolite in skin, on epidermal cells. The putative receptor is involved in keratinocyte chemotaxis toward 12(S)-HETE, which points to its participation in wound healing. In an effort to further characterize the 12(S)-HETE receptor, we investigated its regulation by various cytokines. Of the tested cytokines, only interferon (IFN)-gamma led to a massive induction of the 12(S)-HETE receptors. The effect was dose and time dependent and blocked by cycloheximide. The up-regulation of 12(S)-HETE receptors by IFN-gamma may represent an amplification mechanism of the assumed role of 12(S)-HETE in skin wound repair.

Abstract
Liver, strategically positioned within the circulation system, is a major trap for circulating tumor cells. Trapping and killing of tumor cells may be mediated by Kupffer cells and natural killer cells. In addition to these spontaneously cytotoxic cells, we isolated T-killer cells and antibody-producing cells from the liver after immunization with xenogeneic cells. Since tumor surveillance may include T-killer cells and antibody-dependent killer cells, the liver is able to attack tumor cells by "natural" and "induced" cytotoxic mechanisms.

Abstract
Natural cytotoxic cells from rat spleen and rat liver, (isolated using the collagenase method) were found to be cytotoxic against different lines of human gliomas: T406, T508, T705, HeRo, HeRoCl 1, HeRoCl 8, and HeRo-SV 7/114. After 18 h the lytic units ranged from 75 to 251 in the liver and from 5 to 24 in the spleen. Analyzing the ratio of lysis at 4 h/18 h, it may be concluded that this natural killing is predominantly macrophage (Kupffer cell)-dependent. Lysis by Kupffer cells cannot be increased by transforming glioma cells with SV40. Experiments with SV40-transformed mouse fibroblasts (3T3) and virus-transformed human cell lines (SV80) suggested a "SV40" receptor on Kupffer cells. Thus Kupffer cells have receptors for glioma cells and SV40-dependent membrane structures.

Abstract
Sinusoidal rat liver cells spontaneously kill tumor cells in vitro. They have the same preferences as do spleen cells for certain types of tumor cells, YAC-1, P815, BSP73Asml, BSP73As, EB, EsB, and L5222. Metastasizing tumor cells are less sensitive than their nonmetastasizing counterparts. Not all effector cells are Kupffer cells. These nonmacrophage killer cells share some features with classical natural killers: (a) fast reactions (4 h); (b) high toxicity against YAC-1 cells; (c) sensitivity to anti-asialo GM1 globulin; (d) similar age dependency; (e) short biological halflife (approximately 1 day) (deduced from radiation experiments); (b) silica particle insensitivity; and (g) nonadherence. The natural killing potency of the liver is higher than that of the spleen. The reduction of tumoricidal capacity of the liver in germ-free animals suggests environmental influences. Tumoricidal capacity (organ capacity) is increased in rats chronically fed thioacetamide, carbon tetrachloride (CC14), dimethylaminoazobenzene, and N-nitrosomorpholin.

Abstract
A bibliometric analysis of source items recently published in German-language gynaecology journals and one German-language journal covering a broader field of medicine yielded but one publication linked with prenatally diagnosed congenital malformations and their surgical treatment. Thus, journals usually assessed by the gynaecologist are in this respect at present not a useful source of information for the practitioner outside specialised centres. In order to explore the usefulness of Bildschirmtext (BTX, Videotex), a new electronic medium, as an alternative in counselling for congenital malformations and similar rare medical problems, an experimental database was constructed. Pages giving data on diagnostic pathways, incidence, prognosis, specialised treatment centres and suggested further reading on abdominal wall defects were compiled and are stored in a central computer of the German Federal Postal Services. Data are accessible via the regular telephone network and a specially equipped TV set. The method, although still experimental, is considered useful for offering medical intelligence to the medical professional outside specialised centres.

Abstract
Mammalian erythrocytes loose their normal circulatory pattern following desialylation by sialidase and are trapped in the liver. The mechanism responsible for this phenomenon has been studied by a new scintigraphic method. We report here that the retention of asialo-erythrocytes in the liver is due to the interaction between a lectin-like receptor on Kupffer cells and terminal D-galactosyl residues exposed on erythrocytes after sialidase treatment. The major findings supporting the conclusion are: First, kinetics of asialo-erythrocyte accumulation in the liver are identical in conventional and germfree animals, demonstrating that the presence of serum antibody is not essential. Second, trapping of asialo-erythrocytes can be substantially inhibited by intravenous injection of N-acetyl-D-galactosamine or galactosylated bovine serum albumin, other saccharides or glycoproteins are less or not at all effective. This specificity pattern is characteristic for the D-galactose-specific lectin on Kupffer cells. It therefore appears that the retention of sialidase-treated erythrocytes in the liver is lectin- and not antibody mediated.
