Wild relatives of wheat are one of the important genetic resources for using in breeding programs. In this study, a set of diploid wild wheat possessing D genome (Aegilops tauschii Coss.) were evaluated for some photosynthetic-related traits under two control and water deficit stress conditions. Under stress condition, Analysis of variance showed significant differences among accessions for chlorophyll a, chlorophyll b, carotenoid content, photosynthesis capacity, maximum quantum yield of PSII and seedling fresh and dry biomasses. Water deficit stress reduced all traits and the highest reduction was recorded for seedling fresh and dry biomasses as well as chlorophyll b, respectively. Furthermore, genetic parameters were affected by water deficit stress so that stress condition increased all parameters compared with the control condition. Under stress condition, the genetic gain showed an increasing pattern and it ranged from 3.46 to 54.04. The highest genetic gain value was obtained for the seedling fresh weight (54.04%), chlorophyll b (29.93%) and photosynthesis capacity (26.44%), respectively. In both control and stress conditions, the highest environmental, phenotypic and genotypic coefficient of variances (ECV, PCV and GCV, respectively) were recorded for the last mentioned traits. In general, regarding the high level of genetic diversity in Ae. tauschii species, as well as a high rate of heritability for measured traits, future comprehensive evaluation on this germplasm, is recommended.

Daclizumab is a monoclonal antibody directed against CD25 subunit of interlukin 2 receptor. Several studies have shown the effectiveness of daclizumab on reduction of acute rejection in renal transplantation with regular or limited dose. The present study assessed the outcomes of 3 and 5 years follow-up of a prospective case-control trial comparing safety and efficacy of induction therapy with two doses of daclizumab، compared with no induction treatment، in renal transplant recipients.

This clinical-trial study was started in 2006 on 140 living donor kidney recipients admitted to kidney transplant ward of Kerman Afzalipour hospital، Iran. These patients were randomly assigned into two 70 patients، intervention and control groups. All patients received cyclosporine، mycophenolate mofetil and prednisolone. Intervention group recieved daclizumab at a dose of 1 mg/kg before transplantation and then two weeks later، also. All patients were followed up for 3 and 5 years for graft and patient survival and side effect of daclizumab، so.

After 3 years، 58 patients remained in case and 61 in control group. Function of transplanted kidney was evaluated on base of calculated glomerular filtration rate (GFR)، and after 3 and 5 years، were same between two groups. Rate of sepsis was same between two groups but infection with varicella zuster، in first 6 months after transplantation، was significantly more in intervention group (P = 0. 04).

Daclizumab did not have any effect on patient or graft survival. It did not increase the rate of sepsis but might increase the rate of varicella zuster infection.

Hypertension, hyperuricaemia and nephrotoxicity are some common side-effects of Cyclosporine A (CsA) treatment in renal transplant recipients. Previous studies suggest that Calcium Channel Blockers (CCB) can increase serum level of CsA and may improve graft function in patients receiving CsA. The aim of this study was to evaluate the effects of Diltiazem and Amlodipine on cyclosporine dose adjustment with respect to trough and 2-hour concentrations in renal transplant recipients treated with CsA.

This observer-blind randomized clinical trial was performed on 120 renal transplant recipients treated with CsA. Patients received either Amlodipine (5-10mg/day) or Diltiazem (90-180mg/day) for 3 months and were compared with control group receiving no CCB. Data were analyzed using ANOVA, Post Hoc and Correlation tests.

Diltiazem significantly decreased CsA dosage (20%) from 162.03 ± 40.6 mg/dl to 128.5 ± 25.5 mg/dl (P=0.000) and Amlodipine, too, decreased it to 140.5 ± 22.3 mg/dl (13%) which was significant (P=0.008). Trough concentration in patients who had received Amlodipine were significantly higher than control group (P=0.019). Diltiazem significantly decreased Cholesterol Level (P=0.027) but other parameters were not significantly different between Amlodipine / Diltiazem and control groups.

Diltiazem and Amlodipine were well tolerated in co-administration with CsA with no adverse effect on graft function and did not affect blood pressure or heart rate. Our findings support that these two CCBs can be used in clinical settings to reduce the administered dose of cyclosporine
