Clinical Study of Rhodanese Enzyme in Renal Failure Patients

Rafidain Journal of Science, Volume 28, Issue 4, Pages 1-7

The research involved clinical study of rhodanese enzyme and its relation with some biochemical parameters in renal failure.
The result demonstrated a significant increase in the activity of rhodanese and metallo-endopeptidase and in concentration of urea, and potassium while a significant decrease activity of sulfate oxidase, thiosulfate oxidase and arylesterase and in concentration of albumin and sodium in renal failure patients compared with control.
The results also demonstrated a significant decrease in the activity of rhodanese in male compared with female in each of patients and control groups.
Correlation coefficients between rhodanese and biochemical parameters of renal failure patients showed that activity of rhodanese has negative correlation with activity of sulfate oxidase, thiosulfate oxidase and concentration of albumin while appositive correlation with activity of metallo –endopeptidase and concentration of urea in renal failure patients.
These results provide evidence of a major role for rhodanese enzyme in renal failure, which led to consider it as a marker for renal failure and its relation with biochemical parameters in patients group.

Assessing the Environmental Situation for Excretion Management Stations in Al – Qayyarah Refinery

Rafidain Journal of Science, Volume 28, Issue 4, Pages 8-22

The study was accomplished for the evaluation of the efficiency of the processing station of excretion in Al – Qayyarah refinery, which is located in the area of Al – Qayyarah town toward the south east direction of Mosul city / Iraq. For this purpose, monthly samples were collected for five months from November 2013 to February 2014. Physical, chemical and biological tests were carried out on the samples including Electrical Conductivity, Total Dissolved Solid, Turbidity, Hardness, pH, Sulphate, Sodium and Potassium ions, Heavy metals, Oil,Chemical Oxygen Demandand the Total number of bacteria. The results of this study showed that there was clear variations in the values of those variables before and after treatment,such that values of the acidic function before treatment ranged between (7-8.1) compared with the value after treatment which ranged between (6.9-8.2).the values of Electrical Conductivity was (460-720)µmhos/cm before treatment while the values after treatment was(350-630)µmhos/cm the rate of total hardness before treatment was (233.8) mg/L compared with it’s rate after treatment (238.6) mg/L the nitrates ranged between(0.403-1.341)mg/L before treatment and (0.470-1.423) mg/L after treatment and for sulphate the values ranged between (56.16-67.416) mg/L before treatment compared with values after treatment which was (55.33-69.83) mg/L, the values of concentration for the heavy metals(Pb, Co, Cd, Cu) before treatment was (1.536-1.627), (0.05793-0.06644), (0.04794-0.04821), (0.5378-0.5733) mg/L and thevalues after treatment was (1.324-1.410), (0.06899-0.07814), (0.04845-0.06227), (0.5623-0.5825) mg/L and the total number of bacteria was between (100-1100) cell/ ml before treatment comparedwithresults after treatment (300-3000) cell/ml. The results show that the station’s pollutants removal was not efficient.
