This study was carried out to determine the elimination levels of heavy metal rise resulting from wastewater in agricultural areas irrigated with wastewater, by means of the extraction of the canola (Brassica napus L.) plant. Therefore, the summery Licolly variety of canola (Brassica napus L.) plant was grown by applying wastewater at different moisture levels (Control: 20 kPa, S1: 20 kPa, S2: 35 kPa, S3: 50 kPa, S4: 65 kPa, S5: 80 kPa). Total Cu, Zn, Pb, Cd, Cr, Ni, and Hg concentrations were determined in the harvested plants. At the end of this study, accumulation of Cd, Ni, and Pb could not be determined in the plants, and while the accumulation of Cu, Zn, and Cr was statistically significant, the accumulation of Hg was found to be insignificant.

In this research which was carried out inSuleymanDemirel University Research and Application Farm during 2007 and 2008 years, apple leaf area index (LAI) and leaf water potential (LWP) were observed in Jersey Mac (V1) and Williams Pride (V2) young apple varieties budded on M9 rootstock irrigated with different irrigation methods. Drip (D), subsurface drip (SD), surface (S) and undertree micro sprinkler (M) irrigation methods were used in the research. The amount of applied irrigation water was as much as 100% of Class A Pan evaporation measured during five days irrigation intervals. The amount of irrigation water was ranged between 348.3 (D, SD) – 1186 (S, M) mm depending on irrigation methods during the experimental years. Furthermore, maximum and minimum crop evapotranspiration values were determined as 426.1 (DV2) and 1334.7 (MV2) mm respectively. LAI values related to treatments ranged from 0.32 to 0.52 in 2007, 0.73 to 1.12 in 2008. LAI values increased by approximately 126.3% for all treatments. In both years, generally, the highest LAI values were observed in drip irrigation (D) for both varieties. Linear correlation (r=0.99, n=16) was obtained between fruit yields and leaf area index (LAI) values of the apple trees. Leaf water potential (LWP) measurements were repeated one day before and after irrigation during the irrigation period. The measurements were also conducted once along a day in the middle of the season. Changes in value of LWP were similar among the treatments.

The frequency of obturator nerve damage due to pelvic diseases, fractures or gynecologic procedures is uncertain. In the present study, we investigated the effect of FK506, a potent macrolide antibiotic and immunosuppresant, on obturator nerve recovery at morphological and functional levels. Forty female Wistar rats were randomly divided into four groups (control, sham, FK506-treated, vehicle-treated). In half of animals (FK506-treated and vehicle-treated) an obturator nerve crush (30 seconds clamp) was created. In FK506-treated group FK506 administration (1 mg/kg/day, subcutaneously) was performed on each postoperative day. All the rats were functionally evaluated by pinch and adduction tests preoperatively and postoperatively at one, two, three and four weeks after nerve injury. On the 28th postoperative day obturator nerve samples were collected and analyzed qualitatively by light and electron microscopy. FK506 treatment resulted in dramatic improvement in nerve function and in the ultrastructure of nerve fibers suggesting its therapeutic potential in traumatic obturator nerve injury.
