Sultonium ions are possi sulfur ions with Ihe sulfur bearing three substiiwnts. The best known suifonfwn fan fs S-adenosyknethionine (SAM). SAM has a labile msthyl group and acts as a methyl group donor in many transmethylarton reactions. SAM fs found to be towered in human cirrhosis. About 35 years ago. CMlenger et at.

sulfonium ions, when treated with alkali, were corwetled imo their volatile sultii methyl pfopyl sulftt and methyl butyl suttii. meseions~haveakMlemethylgrwpandmayalsoservea?i methyl donors. The aim of this audy was to develop reliable methods to measure the sutfonium iof0s in urfrm and serum of the dog and to investigate the relation hstwen the concentration of these ions and hepatic enoephalopathy (HE). Resuns: We davelopod a simple and vely sonshtte GC-MS method to measure the dog‘s sulfonium ions, after theic conversion into the respeot’nre sunides, using our advanced technique of he&space sampling and preconcentration onto Tenax trap tubes. Besides in urine. we were able to delect these ices also in serum of the dog. We found four sulfonium ions wkh struuc(ure:R,=methyl and R,=n-pfopyl. iso-butyl, n.butyl, or n-pentyl; X yet unknown. The total concentration d these sulfonium ions in the urine d 18 normal dogs varied from 15 to IW fimoVI. The concernration in serum was about 100 tknes smaller. In 13 out Or 16 dogs with HE, these suKonium fons were CMnplecely absent, while onty 3 dogs gave normal values. Thts dflerence between normal do&s and doas with HE was highly Sign’Mant. The relation between the absence of the dog’s sutkmium ions and the presence of HE has to be further evaluated.

240 ACUTE PHASE REACTION AFTER LIVER TRANSPLANTATION: CYTDKINES AND THEIR PRODUCTS
. 11s. . W.Vocel. W.E.Aulitzkv. M.Herold, R. reiter. C Huber. T.A.Lu~~I Dept.Internal Medicins and Surgery, Univ. Hospital ,Innsbruck, Austria Dept.Derm.11, Vienna The aim of this study was to investigate serum levels of tumor necrosis factor alpha (TNF-a), IL-S, neopterin and C-reactiveprotein (CRP) in patients after orthotopic liver transplantation and to relate findings to clinical complications. Serum samples were collected from 16 patients every alternate day from transplantation until discharge. Concentrations of TNF-a and neopterin were performed using commercially available RIA's. CRP wa* measured with a nephelometric method and IL-6 using a sensitive bioassay. In six out of eight patients with acute cellular rejections, elevated levels of TNF-a and neopterin were detected. IL-6 and CRP concentrations were only markedly elevated in three out. of eight rejection cases. Bacterial infections- showed a different pattern with primarily increased concantrations of IL-6 and CRP. The highest absolute levels of TNF-a and IL-6 were observed in a patient with severe CMV disease. Evaluation of TNF-a. IL-S. CRP and neopterin may be useful in distinguishing typical complications following liver TX.
