ABSTRACT
We show that electronic Raman scattering affords a window into the essential properties of the pairing potential V(k,k') of iron-based superconductors. In Ba0.6K0.4Fe2As2 we observe band dependent energy gaps along with excitonic Bardasis-Schrieffer modes characterizing, respectively, the dominant and subdominant pairing channel. The d(x(2)-y(2)) symmetry of all excitons allows us to identify the subdominant channel to originate from the interaction between the electron bands. Consequently, the dominant channel driving superconductivity results from the interaction between the electron and hole bands and has the full lattice symmetry. The results in Rb(0.8)Fe(1.6)Se(2) along with earlier ones in Ba(Fe(0.939)Co(0.061))(2)As(2) highlight the influence of the Fermi surface topology on the pairing interactions.

1013 ALAT-attacks--in addition to the frequent asymptomatic onset of the disease and the high tendency of chronicity a typical symptom of the non-A, non-B hepatitis--were statistically analysed on 333 patients (of these 216 with uniform parenteral source of infection). 52% of the patients showed a multiphasic course. The aim of the analysis was the exact mathematical description of the attack-behaviour and the discovery of presumed regularities. The investigation of the periodicity of the attacks showed a maxima of spectral density corresponding to a 7-day-rhythm. The trend function of the ALAT-amplitudes in the time-course was assessed as an exponential function. Between mono- and multiphasic ALAT-courses no significant differences existed concerning the clinical picture (icteric--anicteric--subclinical), but as regards the late prognosis the multiphasic courses exhibited highly-significantly more transitions into chronic hepatitis. From the time-serial analysis of the attacks can be deduced for practical application that the reliable detection of non-A, non-B hepatitis cannot be guaranteed with weekly screenings. Screenings at 2-day-intervals which take into consideration the attack-behaviour and the ascertained time of incubation are recommended.

It is reported on immunoglobulin long-term courses in 107 female patients with non-A/non-B-hepatitis. There were statistically significant differences between the group with healing (n = 35) and the group with chronic persisting hepatitis (n = 70) in the IgG- and IgA-values. The immunoglobulin courses in the chronic aggressive hepatitides (n = 2) were not statistically evaluated on account of the small number of cases. It is concluded (in analogy to the investigations of the behaviour of immunoglobulins in hepatitis B) that particularly the IgG course analysis is suitable to reveal the chronification of the non-A/non-B-hepatitis prognostically with high probability.
