The calcineurin inhibitors (CNIs) [cyclosporin A (CsA) and tacrolimus (Tac)] are currently the most widely prescribed drugs for maintenance of immunosuppression after renal transplantation. These immunosuppressants are associated with side effects such as hyperlipidemia. We evaluated the differential effects of different CNIs on serum lipid parameters in renal transplant patients. Moreover, the aim of this study is to investigate the relationships between doses and blood levels of CNIs, and blood levels of CNIs and lipid parameters retrospectively. Two groups of 98 non-diabetic renal transplant patients, each treated with different CNIs, were studied: group A (n = 50, mean age: 31 ± 10 years), CsA, mycophenolate mofetil/azathioprin, steroid; group B (I = 48, mean age: 34 ± 12 years), Tac, mycophenolate mofetil/azathioprin, steroid. In renal transplant patients, CNIs blood levels and doses were examined at 1, 3, 6, 9, and 12 months after transplantation. Biochemical laboratory parameters including plasma lipids [total-cholesterol (CHOL), low-density lipoprotein (LDL)–CHOL, high-density lipoprotein (HDL)–CHOL, and triglycerides (TG)], CNI levels and doses were examined at 1, 3, 6, 9, and 12 months after transplantation. None of the patients received anti-lipidemic drugs during the study period. Blood levels of CNIs were detectable in all whole-blood samples by Cloned- Enzyme-Donor Immunoassay (CEDIA). The relationship between CNIs blood levels and CHOL, (LDL)–CHOL, HDL–CHOL, TG were evaluated. The mean serum CHOL levels and LDL–CHOL levels of patients in group A were found significantly higher than the patients in group B during the 12 month of follow up (p < 0.05). There was no significant difference in TG and HDL–CHOL plasma levels between group A and group B (p > 0.005). In group A the daily dose of CsA was significantly correlated with the mean blood levels of CsA at the 1st and 3rd months (r = 0.387, p = 0.005; r = 0.386, p = 0.006), respectively. In group A, the daily dose of CsA was significantly correlated with the mean serum TG levels during the 12 month of follow up (r = 0.420, p = 0.003). In group B, the daily dose of Tac was significantly correlated with the mean blood level of Tac (r = 0.335, p = 0.020) at the 1st month. No correlation was found between mean Tac blood levels and lipid parameters during the 12-month of follow up (p > 0.05). Significant positive correlation was observed between the CsA blood levels and LDL–CHOL levels (r = 0.338, p = 0.027) at the 3rd month. In the renal transplant patients with well functioning grafts, CsA therapy is associated with increased CHOL and LDL–CHOL ratio which represents an increased atherogenic risk tended to be associated with CsA. Serum LDL–CHOL levels may be effected by blood CsA levels.  相似文献

Chen Peng  Zhou Jun-fu 《浙江大学学报(A卷英文版)》2001,2(4):448-452

Objective: To study the changes of oxidative metabolism and lipoperoxidative metabolism in patients with acute viral myocarditis (AVM), and to research pathological chain reactions of a series of free radicals, and oxidative damage and lipoperoxidative damage in AVM patients' bodies. Methods: A random paired control design was used to investigate 70 cases of AVM patients and 70 cases of healthy adult volunteers (HAV) on the basis of contents of nitric oxide (NO), lipoperoxide (LPO) in plasma, and LPO in red blood cell (RBC) as well as activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) in RBC as revealed by spectrophotometric assays. Results: Compared with the average values (AV) of the above biochemical parameters (BP) in the HAV group, the AV of NO in plasma, and LPO in plasma and in RBC in the AVM group were significantly increased (P=0.0001), while the AV of SOD, CAT and GSH-Px in the AVM group were significantly decreased (P=0.0001). Conclusion: The findings in this study suggested that in the AVM patients bodies the metabolism of NO was disturbed, and the pathological chain reactions of a series of free radicals were so severely aggravated, as to cause the oxidative damage and lipoperoxidative damage in the AVM patients' bodies.  相似文献

Sulfide-containing waste streams are generated by a number of industries. It is emitted into the environment as dis- solved sulfide (S2- and HS-) in wastewaters and as H2S in waste gases. Due to its corrosive nature, biological hydrogen sulfide removal processes are being investigated to overcome the chemical and disposal costs associated with existing chemically based removal processes. The nitrogen and sulfur metabolism interacts at various levels of the wastewater treatment process. Hence, the sulfur cycle offers possibilities to integrate nitrogen removal in the treatment process, which needs to be further optimized by appropriate design of the reactor configuration, optimization of performance parameters, retention of biomass and optimization of biomass growth. The present paper reviews the biotechnological advances to remove sulfides from various environments.  相似文献
