These findings are consistent with the observation that jntestinal lymphocytes newly formed in mesenteric lymph nodes predominantly home in on the intestine again.\& The degree of histologic alteration within different tissues indicates that the graft and the host may survive the lesions of the lymphatic tissues, whereas the severe intestinal lesions following GVHR may easily cause death of the recipient. With regard to clinical sman bowel transplantation two statements can be made: (l) GVHRIL play a significant role in small bowel trans~ plantation. (2) To minimize their biologic importance, a selective elimination of the graft's Jymph nodes by irradiation or surgical resection should be considered in view of the remarkable difference between GVHRIL in lymph nodes and in the graft's intestinal wall itself.}, subject = {Chirurgie}, language = {en} } @article{WaagaKrzymanskiUlrichsetal.1993, author = {Waaga, AM and Krzymanski, M. and Ulrichs, Karin and Wierusz-Wysocka, Bogna and M{\"u}ller-Buchholtz, Wolfgang}, title = {Hematological effects of the new immunosuppressive drug 15-deoxyspergualin}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-44701}, year = {1993}, abstract = {Since systematic hematological studies on blood and bone marrow changes after treatment with 15-Deoxyspergualin (DOS) are lacking, a quantitative assessment was performed fourteen or twenty eight days after intraperitoneal application of DOS to rats. Further observations done 7 and 14 days after discontinuation of DOS administration allowed analysis of banc marrow regeneration. DOS induced lymphocytopenia, granUlocytopenia and anemia with a decrease of bone marrow cellularity due to suppression of cell maturation. The effect was dose-dependent and bone marrow as well as blood changes were observed in animals treated with doses from 0.5 to 10.0 mg/kg DOS. Within 14 days after termination of the treatment, rapid recovery with normalization of all hematological parameters was observed. In the light of our data, these hematological side effects may not be a major disadvantage, if DOS is used in doses below 2.5 mg/kg, and for a course of therapy which is limited to 7 to 14 days.}, subject = {Chirurgie}, language = {en} } @article{WinotoMorbachUlrichsHeringetal.1990, author = {Winoto-Morbach, S. and Ulrichs, Karin and Hering, BJ and Leyhausen, G. and M{\"u}ller-Ruchholtz, W.}, title = {Lectins for electromagnetic purification of islets from humans and large mammals}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-45430}, year = {1990}, abstract = {No abstract available}, subject = {Chirurgie}, language = {en} } @article{KekowUlrichsMuellerRuchholtzetal.1988, author = {Kekow, J{\"o}rn and Ulrichs, Karin and M{\"u}ller-Ruchholtz, Wolfgang and Gross, Wolfgang L.}, title = {Measurement of rat insulin.

IR! measurement in rats can be made more sensitive, accurate, and practical, as demonstrated by a new modified enzyme-linked immunosorbent assay (ELlSA). It is characterized by indirect binding of an anti-insulin antibody by an antiglobulin antibody and uses the principle of competitive saturation. In this ELlSA, IRI can be determined in a wide range of concentrations, corresponding to the standards. The standard curve ranges from 100 to 0.049 ng/mllRI (1 ng/ml - 23.4 JLU/ml - 172 pM rat insulin). The statistical analysis shows between- and within-assay coefficients of variation of :515\%.
