    Description / Table of Contents: Zusammenfassung Der genetische Polymorphismus des menschlichen Inter-Alpha-Trypsin-Inhibitors (ITI) wurde mit Hilfe der isoelektrischen Fokussierung an Sialidase-behandelten Seren untersucht. Der pH-Bereich war von 3,5 bis 9,5, an die Elektrophorese schloß sich ein passiver Blot an mit anschließendem Enzym-ImmunoEssay. Bei 400 Blutspendern aus West-Japan wurden 8 vereinfachte Bandenmuster beobachtet, von denen 6 durch die bereits früher beschriebenen polymorphen Allele ITI*1, ITI*2 und ITI*3 erklärt werden konnten. Die anderen Phänotypen waren Produkte eines neuen und seltenen 4. Allels, welches als ITI*4 bezeichnet wurde und dessen Expression ebenfalls mit der Annahme eines autosomalen kodominanten Erbganges konsistent ist. Die Frequenz dieser Allele war 0,440, 0,526, 0,030 und 0,004. Die theoretische Ausschließungschance für Putativväter in Vaterschaftsfällen wurde mit 0,228 errechnet. Das ITI-System ist ein nützlicher genetischer Marker für die forensische Hämogenetik in der japanischen und europäischen Bevölkerung.
    Notes: Summary The genetic polymorphism of human interalpha-trypsin inhibitor (ITI) has been investigated in sialidase-treated samples by isoelectric focusing on polyarcrylamide gels with a pH range 3.5–9.5 followed by passive blotting with enzyme immunoassay. In 400 blood donors from western Japan, 8 simplified band patterns were observed, 6 of which could be explained by the previously described 3 polymorphic alleles, ITI*1, ITI*2, and ITI*3. The others were products of a new and rare fourth allele designated ITI*4, whose expression is also consistent with autosomal codominant inheritance. The frequency of these alleles was 0.440, 0.526, 0.030 and 0.004, respectively. The theoretical exclusion rate for putative fathers in paternity cases was calculated to be 0.228. The ITI system is a useful genetic marker for forensic hemogenetics in Japanese and in Europeans.

    Notes: Abstract Interleukin-1 (IL-1β), tumour necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) were measured in serum from children with measles using an immunoradiometric assay. The IFN-γ level was increased in 52 out of 54 patients in the acute phase of measles (〈7 days of illness), and then declined to an undetectable level in the convalescent phase. Neither IL-1 nor TNF could be detected during the course of the illness. The mean serum IFN-γ level was at its peak on day 4 and could be detected over a 7-day period after the onset of fever, coinciding with the febrile period (6.9±1.5 days). In the acute phase, the phytohaemagglutinin responses, absolute number of platelets, total lymphocyte counts, CD3+, CD4+, CD8+ cell counts and the CD4/8 ratio were depressed, while stab cell number and lactate dehydrogenase levels were higher than those in the convalescent phase. Using Spearman rank sum test, the IFN-γ level was correlated negatively with the peripheral lymphocyte (P〈0.01), CD3+ (P〈0.05), CD4+ (P〈0.05) cell counts and the CD4/8 ratio (P〈0.05) and correlated positively with the stab cell count (P〈0.01) but not with any other parameter. When the acute phase findings were compared between 28 complicated and 40 uncomplicated patients, the former were younger (P〈0.01) and had higher maximum body temperature during the illness (P〈0.05) than the latter, there was no difference in their IFN-γ levels. These results show that endogenous IFN-γ appears in the circulation during the acute febrile phase of measles, but does not contribute directly to any complication of the disease.
