Tibody EIA using the neoepitope-specific MoAb aE11 as PI3Kδ-IN-2 catching antibody. Albumin escape rate (AER; tc 99m-labeled albumin), serum protein (S-Protein), and hematocrit (Hct) were determined. After verifying typical information distribution (skewness < 1.5) Student's t-test was performed by rankordered stepwise testing. Data are mean ?SD. Results: Septic animals showed marked renal deposition of TCC. Other results, see Table.Table Baseline Sepsis TCC ( ) S-Protein (g/l) AER ( ) Hct ( ) 29 ?1 29 ?2 104 ?40 43 ?4 Control 118 ?37 42 ?2 SepsisConclusion: Although plasma levels of TCC declined over study period, in septic animals marked renal depositions of TCC indicated complement activation. Since AER increased and serum protein levels decreased, capillary loss of TCC into organ tissue may explain our findings in part. We conclude that in septic shock with substantial CLS plasma levels of TCC may not reflect degree of complement activation.Reference:1.

Methods: Over a 6 month period 35 patients with proven infection and severe sepsis or septic shock for at least 3 days' duration were monitored on a daily basis during their stay in the intensive care unit (ICU) until discharge from the ICU or death. In 19 out of these 35 patients one or more peaks in G-CSF serum concentrations occurred. Eleven of these 19 patients survived, eight patients died. A longitudinal analysis of G-CSF serum concentrations, phagocytotic activity of granulocytes and surface expression of monomeric Fc receptor type I (CD64, FcRI) on granulocytes was performed by ELISA technique (R D Systems, Minneapolis, MN, USA) and flow cytometry (PhagotestTM; Orpegen, Heidelberg, Germany) and CD64 (clone 22; Immunotech, Krefeld, Germany), respectively on a daily basis. Results: A G-CSF peak was defined as an increase of at least 30 from one day to the other, followed by a decrease of at least 15 on the next day. The following results are expressed as median (min ?max) values. In seven episodes there was a parallel course of the G-CSF peak and phagocytosis with an increase in phagocytosis by 37 (6?0 ). In 11 episodes, phagocytosis continuously increased and remained on a higher level after the increase of 10 (1?64 ) from day 1 up to day 2. In 10 episodes, there was a decrease by 40 (17?6 ) at the day of the G-CSF peak, followed by an increase by 58 (6?22 ) on the next day. In 12 episodes, there was no increase PubMed ID: (n = 4) or perhaps a lower (n = 8) by 24 (three?six ) more than all days. Conclusions: A peak in G-CSF serum concentration was followed by a continuous improve in phagocytosis at the similar day in 7, and a delayed improve in 21 out of 40 episodes, but no raise or even.
