Coliform bacteria and nitrate levels were examined by multiple tube fermentation method and ultraviolet spectrophotometric screening method, respectively. The values of fecal coliforms and total coliforms were expressed in most probable number/100 mL. PH was measured in the field. It was noticed that significantly (P<0.05) lowest means of fecal coliforms (191.00±29.04), total coliforms (523.33±35.19) and nitrate (2.97±0.05 mg/lit) were in station 1 that was located at the most upstream point. The downstream stations showed the highest levels of fecal coliforms (800.00±00.00), total coliforms (1600.00±00.00) and nitrate (16.00±0.01 mg/lit) as a result of domestic sewage discharges and agricultural land runoff. No significant differences found between pH levels in the stations. Nonsignificant variations were observed with regard to pH, nitrate and coliforms concentrations in the studied months at 95% confidence level. Fecal and total coliform counts were positively correlated with each other and with nitrate levels (P<0.01). There was also a positive correlation between pH and total coliform levels at 95% confidence level.

The aim of this study were to evaluate expression level of FasL in whole blood from patients with Relapsing-Remitting (RR) form of MS, and to survey the association of FasL expression with risk, Expanded Disability Status Scale (EDSS) and duration of the disease. We compared FasL expression in 50 RR-MS patients with 50 healthy controls by Taqman Real time PCR technique.
