Nuclear stopping from 0.09A to 1.93A GeV and its correlation to flow.

We present a complete systematics (excitation functions and system-size dependences) of global stopping and side flow for heavy ion reactions in the energy range between 0.09A and 1.93A GeV. For the heaviest system, Au+Au, we observe a plateau of maximal stopping extending from about 0.2A to 0.8A GeV with a fast drop on both sides. The degree of stopping, which is shown to remain significantly below the expectations of a full stopping scenario, is found to be highly correlated to the amount of side flow.

Azimuthal dependence of collective expansion for symmetric heavy-ion collisions.

Detailed studies of the azimuthal dependence of the mean fragment and flow energies in the Au+Au and Xe+CsI systems are reported as a function of incident energy and centrality. Comparisons between data and model calculations show that the flow energy values along different azimuthal directions could be viewed as snapshots of the fireball expansion with different exposure times. For the same number of participating nucleons more transversally elongated participant shapes from the heavier system produce less collective transverse energy. Good agreement with Boltzmann-Uehling-Uhlenbeck calculations is obtained for a soft nuclear equation of state.

[Incidence and clinical manifestations of hepatitis C virus infection in patients on hemodialysis].

Hepatitis C virus infection is a very important problem among patients on maintenance hemodialysis. To determine incidence and clinical manifestations of hepatitis C virus infection, we tested blood samples of patients on hemodialysis in 1992 and 1994 using ELISA a HCV test of second generation. In 1992 46 out of 119 patients (38%), and in 1994 36 out of 122 (29%) patients on hemodialysis were aHCV positive. Duration of dialysis program and level of serum aminotransferases were significantly higher in the group of aHCV positive patients had received more blood transfusions per year, but not significantly higher than HCV negative patients. These results with knowledge about common routes of HCV transmission, demand strict preventive measures in dialysis units, routine and regular HCV testing of patients' blood samples and serum aminotransferases level, and isolation of HCV positive patients and machines.

[The effect of septic complications on recovery in acute renal insufficiency in patients with multiple injuries].

Septic complication in patients (pts) with ARF are among the most important causes of mortality, especially in pts with polytrauma and multiple-organ failure. Prevention procedures, early and accurate diagnosis and persistent treatment in time are necessary to avoid septic shock. During the period od 27 months (1992-1994), 25 pts with wounds inflicted in war and AFT were treated by haemodialysis. Eighteen (72%) pts had septic complication. Eleven (71%) of them recovered from ARF, while 7 (39%) pts died despite the undertaken procedures. Nine pts (81%) with septic complication and ARF who improved their renal function were treated by one or more nephrotoxic antibiotics. Haemodialysis was initiated when average BUN concentration was 35.7 mmol/l and plasma creatinine level about 0.8 mmol/l. Simultaneously with symptomatic and substituting therapy, and surgical correction of polytrauma, approximately 9 haemodialysis in the period of 21 day were necessary for ARF recovery. In the group of pts who had no improvement of renal function, 6 (85%) received 1 or more nephrotoxic drugs. Approximately 5 haemodialysis were done in these pts, in a shorter period of time. In polytraumatized pts with ARF with septic complication, factors which potentiate hypercatabolism aggravate the prognosis of ARF, increase mortality, require a greater number of haemodialysis and significantly prolong the recovery time of ARF.
