The possible role of curcumins in protecting the pulmonary function of smokers should be further investigated in clinical studies.AcknowledgmentsWe thank the MedChemExpress Indolactam V participants in South East Singapore, Geylang East Home for the Aged, Presbysterian Community Services, Thye Hua Kuan Moral Society, Henderson Senior Citizens’ Home, and People’s Association for their support and assistance in the study.

Impaired renal function is frequently observed in patients with renal allograft. Deterioration of renal transplant function is mostly due to chronic allograft nephropathy, which is characterized by chronic interstitial fibrosis, tubular atrophy, vascular occlusive changes, and glomerulosclerosis [1]. Gray-scale ultrasound and Doppler TBHQ web measurements are established noninvasive imaging techniques which have become a routine method for evaluating kidney allografts. Morphologic changes, including the size, parenchymal echogenicity, and corticomedullary differentiation, of the kidney allograft on gray-scale ultrasound may occur in a graft with dysfunction. Furthermore, Doppler measurements may aid in the management of established renal disease by identifying complications in the allograft. Previous studies showed discrepant results whether renal arterial resistive index may predict future events, for example the decrease of 50 or more in creatinine clearance, allograft failure, or death [2?]. However, for clinical practice, measurements of renal arterial resistive index are even more important to highlight the current status of renal allografts. To date there are no data available about the validation of the renal arterial resistive index in terms of stage of kidney disease. Now, we investigated the optimal threshold value of renalarterial resistive index as assessed by Doppler ultrasonography determining chronic kidney disease stage 4 or higher in patients with renal allograft.Patients and Methods Ethics StatementAll research involving human participants was approved by the local ethics committee (Den Videnskabsetiske Komite for Region Syddanmark, reference number: S-20070059). Informed consent was obtained and all clinical investigation has been conducted according to the principles expressed in the Declaration of Helsinki. Written informed consent was obtained from all patients before entry into the study. In a cross-sectional study Doppler ultrasonography of the kidney graft was performed in 78 consecutive patients (53 male, 25 female; median age, 54 years, interquartile range, 44 to 66 years) with renal allograft at least three months after transplantation who were seen in our outpatient clinic. Inclusion criteria were the following: 1. Patient with renal allograft at least three months after transplantation. 2. No signs of apparent intercurrent illness. 3. Presence of informed consent. Exclusion criteria were the following: 1. Absence of informed consent. 48 patients (62 )Renal Arterial Resistive Indexreceived kidneys from living related donors, 30 patients (38 ) from deceased donors, and median time interval since transplantation was 35 months (interquartile range, 10 to 88 months). At the time of the present investigation all patients were amb.On pulmonary function.
