The results of an experimental and clinical study on the benzydamine binding and distribution in vaginal mucosa are presented, employing benzydamine solution for gynaecological use. When applied first to rats, the mean amount of the drug in their vaginal mucosa became 3.65 +/- 2.99 micrograms/g of fresh tissue with a significant difference between control and treated animals, without detectable amounts in the plasma. When applied to humans, the mean amount of benzydamine assayed in 17 specimens of vaginal mucosa was 9.72 +/- 6.24 micrograms/g. It was greater than the range of animal anti-inflammatory concentration (2-8 micrograms/g) established by pharmacological studies on this drug and justified the local benefits from benzydamine treatment of vaginal inflammation. Benzydamine assayed in seven volunteers with healthy vaginas showed that the drug cannot be detected in the plasma. 相似文献

The aim of this study is to valorize the watermelon seeds treated with hexane for the removal of reactive yellow 145 from aqueous solutions. The effects of physico-chemical parameters such as pH, adsorbent dose, temperature and dye concentration on the removal of dyes were evaluated. The kinetic study of the adsorption of reactive yellow 145 on watermelon seeds adsorbent perfectly followed the pseudo-second-order kinetic model. The Langmuir, Freundlich, Temkin, Elovich and Dubinin-Radushkevich models were studied. It was proved that the experimental data fitted well to the Freundlich model, which signifies that the phenomenon of adsorption is done in multilayers on heterogeneous surfaces. The finding of this paper asserts that this material is a good and low-cost adsorbent that can be used for the removal of dyes from aqueous solutions. 相似文献

Introduction
Cyclophosphamide (CPM) is used empirically in the treatment of progressive multiple sclerosis. The purpose of this study was to evaluate its efficacy in naive patients with progressive multiple sclerosis.Patients and methods
Thirty-one patients were retrospectively included (17 secondary multiple sclerosis, 14 primary progressive multiple sclerosis), and received infusions of CPM (600 mg/m2) every eight weeks, for 18 months. Evaluation was based on time to EDSS progress.Results
Among patients with secondary progressive multiple sclerosis, 94% were stable or improved at six months, 77% at 12 months, and 75% at 18 months. The same result was reported in 69.2% of primary progressive multiple sclerosis at six months, 64% at 12 months, and 55.5% at 18 months. We found no difference between the two groups.Conclusion
Our results suggest that the CPM is efficient in progressive multiple sclerosis; however, its place must be reconsidered before establishing an international consensus for treatment; open label studies are needed to validate the present findings. 相似文献15.

Purpose Insulin resistance, implying depressed cellular sensitivity to insulin, is a risk factor for type 2 diabetes and cardiovascular
disease. This study is the first step towards the development of a technique of insulin resistance measurement in humans with
a new tracer of glucose transport, [123I]6-deoxy-6-iodo-D-glucose (6DIG).
Methods We investigated 6DIG kinetics in anaesthetised control rats and in three models of insulin-resistant rats: fructose fed, Zucker
and ZDF. The study of myocardial 6DIG activity was performed under two conditions: first, 6DIG was injected under the baseline
condition and then it was injected after a bolus injection of insulin. After each injection, radioactivity was measured over
45 min by external detection via NaI probes, in the heart and blood. A tri-compartment model was developed to obtain fractional
transfer coefficients of 6DIG from the blood to the heart.
Results These coefficients were significantly increased with insulin in control rats and did not change significantly in insulin-resistant
rats. The ratio of the coefficient obtained under insulin to that obtained under basal conditions gave an index of cardiac
insulin resistance for each animal. The mean values of these ratios were significantly lower in insulin-resistant than in
control rats: 1.16 ± 0.06 vs 2.28 ± 0.18 (p < 0.001) for the fructose-fed group, 0.92 ± 0.05 vs 1.62 ± 0.25 (p < 0.01) for the Zucker group and 1.34 ± 0.06 vs 2.01 ± 0.26 (p < 0.05) for the ZDF group.
Conclusion These results show that 6DIG could be a useful tracer to image cardiac insulin resistance. 相似文献

Alcohol consumption may be associated with risk of colorectal cancer (CRC), but the epidemiological evidence for an association with specific anatomical subsites, types of alcoholic beverages and current vs. lifetime alcohol intake is inconsistent. Within the European Prospective Investigation into Cancer and Nutrition (EPIC), 478,732 study subjects free of cancer at enrolment between 1992 and 2000 were followed up for an average of 6.2 years, during which 1,833 CRC cases were observed. Detailed information on consumption of alcoholic beverages at baseline (all cases) and during lifetime (1,447 CRC cases, 69% of the cohort) was collected from questionnaires. Cox proportional hazard models were used to examine the alcohol-CRC association. After adjustment for potential confounding factors, lifetime alcohol intake was significantly positively associated to CRC risk (hazard ratio, HR=1.08, 95%CI=1.04-1.12 for 15 g/day increase), with higher cancer risks observed in the rectum (HR=1.12, 95%CI=1.06-1.18) than distal colon (HR=1.08, 95%CI=1.01-1.16), and proximal colon (HR=1.02, 95%CI=0.92-1.12). Similar results were observed for baseline alcohol intake. When assessed by alcoholic beverages at baseline, the CRC risk for beer (HR=1.38, 95%CI=1.08-1.77 for 20-39.9 vs. 0.1-2.9 g/day) was higher than wine (HR=1.21, 95%CI=1.02-1.44), although the two risk estimates were not significantly different from each other. Higher HRs for baseline alcohol were observed for low levels of folate intake (1.13, 95%CI=1.06-1.20 for 15 g/day increase) compared to high folate intake (1.03, 95%CI=0.98-1.09). In this large European cohort, both lifetime and baseline alcohol consumption increase colon and rectum cancer risk, with more apparent risk increases for alcohol intakes greater than 30 g/day. 相似文献

We conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition, to examine the associations between prediagnostic serum concentrations of C-peptide, insulin-like growth factor binding protein (IGFBP)-1 and IGFBP-2, and endometrial cancer risk. Among pre- and post-menopausal women, who were not currently using exogenous hormones, 286 women developed incident endometrial cancer during an average 5.1 years follow-up. Using risk set sampling, 555 matched control subjects were selected. In conditional logistic regression models adjusted for matching factors only, endometrial cancer risk increased with increasing serum levels of C-peptide (relative risks (RR) for the top vs. bottom quartile = 2.13 [95% confidence interval (CI) 1.33-3.41], p(trend) = 0.001, and decreasing serum levels of IGFBP-2 (RR for the top vs. bottom quartile = 0.56 [95% CI 0.35-0.90], p(trend) = 0.03, but was not significantly associated with IGFBP-1 levels (RR for the top vs. bottom quartile = 0.76 [95% CI 0.47-1.21], p(trend) = 0.25). In BMI-adjusted models, only the C-peptide association remained marginally statistically significant (RR for the top vs. bottom quartile = 1.56 [95% CI 0.94-2.57], p(trend) = 0.05 for C-peptide; 0.84 [95% CI 0.50-1.40], p(trend) = 0.74 for IGFBP-2; and 1.08 [95% CI 0.65-1.78], p(trend) = 0.86 for IGFBP-1 levels). These associations were stronger among nonfasting women (< or =< or =6 hr since last meal; 63% of subjects) but were not evident among fasting women, although the interactions were not statistically significant. The C-peptide-risk association was substantially attenuated after adjustment for free estradiol in postmenopausal women (RR for the top vs. bottom quartile = 1.28 [95% CI 0.67-2.45], p(trend) = 0.42. Our results provide modest support to the hypothesis that hyperinsulinaemia is a risk factor for endometrial cancer. 相似文献

A 14-year-old girl with juvenile dermatomyositis developed extensive and debilitating calcinosis, unresponsive to colchicine, while muscle involvement subsided. Pamidronate (2 mg/kg/year) produced dramatic improvement of pain and function within 2 months and calcinosis had completely resolved by 2 years. No new calcifications have been noted with a 5-year follow-up. 相似文献

OBJECTIVES: intermittent pneumatic compression (IPC), an established method of deep-vein thrombosis prophylaxis, is also an effective means of leg inflow enhancement, improving the walking capacity and ankle pressure of claudicants, long-term. This study, using duplex ultrasonography, compares the haemodynamic effect of IPC of the (a) foot (at 120 mmHg [IPC(foot/120 mmHg)], and 180 mmHg [IPC(foot/180 mmHg)]), (b) calf (IPC(calf), 120 mmHg) and (c) both simultaneously (IPC(foot+calf), 120 mmHg), on the venous outflow of 20 legs of normals and 25 legs of claudicants. RESULTS: the peak and mean velocities, volume flow and pulsatility index in the superficial femoral and popliteal veins of both groups increased significantly with all IPC modes (p<0.001). IPC(foot+calf)produced the highest enhancement followed by IPC(calf)(p<0.01), which was more effective (p<0.001) than either IPC(foot/180 mmHg)or IPC(foot/120 mmHg). The venous volume expelled with IPC(calf)and IPC(foot+calf)was 2-2.5 and 3-3.5 times that with IPC(foot/180 mmHg)respectively. Velocity enhancement with IPC was similar between groups and the superficial femoral and popliteal veins. IPC(foot/180 mmHg)produced higher (p<0. 01) flow velocities than IPC(foot/120 mmHg)in both groups and veins examined; however, differences were limited. CONCLUSIONS: all IPC modes proved effective, IPC(foot+calf)generating the highest venous outflow enhancement. Higher venous volumes expelled with IPC(foot+calf)explain its reported superiority on leg inflow over the other modes. Increase of applied pressure from 120 to 180 mmHg with IPC(foot)offered only a small outflow improvement. Venous haemodynamics at rest and with IPC in claudicants do not differ significantly from those in healthy subjects. 相似文献
