  The drought stress in one of the most significant environmental stress limiting the plant production over the agricultural lands of the world. Since, the stress caused by the pesticide paraquat (1, 1-dimenthyl-4, 4 bipyridilium dichloride) is similar to water stress which decreases the chlorophyll content of the leaves, paraquat tolerance is successfully used to determine the wheat genotypes resistant to drought. This study was carried to determine the Paraquat (PQ) tolerance of 64 bread wheat genotypes. The parameters of SPAD values before and after paraquat treatments, chlorophyll loss caused by paraquat and correspondingly calculated Paraquat Sensitivity Indexes (PSI) was investigated in this study. Significant differences were observed among the wheat genotypes with regard to all of the investigated parameters. SPAD values of genotypes before PQ treatment varied between 33.6-51.3 and varied between 28.8-47.0 after PQ treatment. Chlorophyll loss of genotypes due to PQ treatments was between 2.0-23.3%. PSI values of genotypes were found to be between 0.18-2.10. The varieties Cetinel, 2000, Alparslan, Sultan 95, Karahan and KirmiziYerli were found to be the most tolerant and Ankara 093/44, Ak 702, Haymana 79 and Conkesme varieties were found to be the most sensitive genotypes.

  Aim:The aim of this study was to elucidate serum levels of IL-6, IL-8, TNF-α, CRP, and HSP 70 in patients with active or inactive Behcet`s disease.
Materials and methods: The study included 50 patients who met the International Study Group criteria for Behcet`s disease. Of these, 26 had active disease and 24 had inactive disease. The control group was comprised of 25 age- and sex-matched healthy participants. Serum levels of IL-6, IL-8, TNF-α , CRP, and HSP 70 were measured.
Results: In patients with active disease, significantly higher mean serum levels of IL-6, IL-8, TNF-α, and CRP were found compared to patients with inactive disease or in controls (overall, P < 0.05). In patients with active disease, the mean serum level of HSP 70 was significantly higher than that of the control group (P = 0.02). In patients with inactive disease it was higher compared to the controls but with a significance level close to 0.05 (P = 0.044). However, HSP 70 levels did not differ significantly between patients with active disease and patients with inactive disease (P = 0.93).
Conclusion: The results of our study suggest that serum IL-6, IL-8, TNF-α, and CRP levels are increased in patients with active Behcet's disease. HSP 70 levels in both active and inactive disease groups were higher than in controls, though it was significant only in the active group. This suggests that HSP 70 has a role in the chronic nature of Behcet`s disease, with HSP 70 expression possibly not falling to normal levels in the inactive phase of the disease.
