Margaret Attwood 《Action Learning: Research and Practice》2007,4(2):191-198
Can the development, both clinical and managerial, of practitioners involved in healthcare be enriched by connecting action learning principles and practice with research on ‘tempered radicals’? Might such connection also assist the efforts of patients and their advocates to create more holistic approaches to patient care? This paper explores these questions with reference to a UK Department of Health project to improve renal services. The prime focus is the experience of a set of set advisers who ‘held the ring’ on the project, supporting the work of the sets and attempting to make sense of the emerging learning. 相似文献

Present investigation shows that hydroethanolic extract of Moringa oleifera (MOHE) and its isolated saponin (SM) attenuates DMBA induced renal carcinogenesis in mice. Isolation of SM was achieved by TLC and HPLC and characterization was done using IR and 1H NMR. Animals were pre-treated with MOHE (200 and 400 mg/kg body weight; p.o), BHA as a standard (0.5 and 1 %) and SM (50 mg/kg body weight) for 21 days prior to the administration of single dose of DMBA (15 mg/kg body weight). Administration of DMBA significantly (p < 0.001) enhanced level of xenobiotic enzymes. It enhanced renal malondialdehyde, with reduction in renal glutathione content, antioxidant enzymes and glutathione-S-transferase. The status of renal aspartate transaminase, alanine transaminase, alkaline phosphatase and total protein content were also found to be decreased along with increase in total cholesterol in DMBA administered mice. Pretreatment with MOHE and SM significantly reversed the DMBA induced alterations in the tissue and effectively suppressed renal oxidative stress and toxicity. 相似文献

Urinary abnormalities were evaluated in 100 renal stone patients with first episode of renal stone having age 22 to 45 years
from both sex and compared to 100 normal healthy control group having same age group from both sex. Twenty-four hours urinary
oxalate, calcium, uric acid, sodium, magnesium, phosphorus and citrate were estimated. The urinary pH was also determined.
In stone formers urinary oxalate, calcium, sodium and uric acid excretions were significantly higher when compared with control
group. Whereas citrate, phosphate and magnesium excretion were significantly lower in stone formers when compared with control.
The pH of urine in stone formers was lower than the controls. High dietary intake of purine rich diet causes elevated excretion
of uric acid, which leads to calcium oxalate crystal formation and precipitation. Other risk factors such as urinary oxalate,
calcium also related to formation of renal calculi.
Hypocitraturia is the main cause of renal calculi along with hypomagnesiuria and hypophosphaturia in the patient of Marathwada
region. On the basis of urinary abnormalities further stone formation in the patient can be prevented by dietary modifications. 相似文献

Accurate monitoring of blood cyclosporin C2 levels is vital to prevent over immunosuppression and acute renal toxicity in
patients who receive organ transplant. The matrix used to dilute patients’ C2 samples prior to the assay affected the final
measured values. Hence there was a need to develop a method of dilution that would accurately estimate C2 levels when cyclosporin
levels were beyond the calibration range of the method employed. Whole blood, cyclosporin free hemolysate and cell and protein
free supernatant obtained after pretreatment of normal blood were used to dilute patients’ C2 samples. C2 was measured in
188 patients using the supernatant method of dilution. C2 was correlated with Co and dose of cyclosporin received by the patient.
The use of cell and protein free supernatant obtained after pretreatment of normal blood as a C2 diluent detected higher levels
of C2 in the sample. Measured C2 correlated significantly with Co and the cyclosporin dose received by the patient. The uniformly
aqueous cell and protein free supernatant ensures uniform dilution of the patients’ C2 sample and measures higher cyclosporin
levels. 相似文献

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

Vitamin B12 being water soluble is excreted in the urine when administered in excess. The probability of finding an abnormally excess
serum concentration would be almost surreal. We report a peculiar clinical situation that may impact the vitamin B12 immunoassay on the Roche Elecsys 2010 due to excess analyte concentration. In separate episodes (Feb and June 2010), the
Biochemistry laboratory of a tertiary-care hospital, Kolkata, India, encountered two critically ill patients with background
chronic kidney disease (CKD), low urine output, and on cyanocoabalamin supplementation, who had serum vitamin B12 concentrations far exceeding expected values; even post dialysis. The B12 assays (pmol/l) were performed using electrochemiluminiscence immunoassay on Roche Elecsys 2010, the assay validity confirmed
by concomitant quality control runs. The immunoassays failed to deliver results, flagged with “signal level below limit”. Biotin therapy was ruled out as a possible interferent. In the first episode, re-assay of a repeat draw yielded same outcome;
outsourcing on Immulite provided concentration of >738 pmol/l. Serial dilution gave result of >29520 pmol/l on Elecsys 2010.
In the second, we gained from past experience. Vitamin B12 concentration >59040 pmol/l was conveyed to the treating nephrologist the very day. The B12 immunoassay on the Elecsys 2010 employs sequential incubation steps for competitive binding that is compromised in the event
of abnormally excess B12 concentration in patient sera akin to the prozone effect. This knowledge may be beneficial while assaying sera of CKD patients
to avoid financial loss due unnecessary repeats and delay in turnaround time. 相似文献
