Such research evidence as exists on effective drug strategies in prevention and education draws attention to the importance of involving parents along with other community agencies and school governors. Much depends nevertheless on the way in which 'involvement' is interpreted and the assumptions that are made about parents' knowledge of drugs and drug education as well as their attitudes to drug issues. As the age of initial experimentation and contact with drugs continues to fall, the importance of enskilling parents to support drug education programmes for 5 year olds and upwards continues to rise. This paper reports the first wide ranging survey of parents' knowledge of drugs and drug issues across an entire English county embracing younger as well as older children. The need for more coordinated, informed and systematic guidance to parents is established. 相似文献

Day care surgery in otolaryngology is gradually gaining popularity all around the world and the scope of day care surgery has improved significantly in recent years. 380 patients underwent ear, nose and throat surgery during the period Sep 2002–Aug2004. All the cases were done under local anaesthesia. Strict criteria were adopted for admission and discharge of the patients. Most of the patients (90.6%) who underwent ENT day care surgery did not experience unusual peroperative or postoperative discomfort. There was no case requiring postoperative admission to a hospital. There was a high degree of patient preference and satisfaction to day care surgery. Following proper guide lines for day care surgery and strict admission and discharge criteria has gone a long way in making day care surgery a success. It can be concluded that high medical standards can be achieved with low expenditure with this form of management. 相似文献

The kinetics and mechanism of the inhibiting action of toluene on the Ce(IV) initiated polymerization of acrylonitrile were studied together with the effects of [M], [Ce(IV)], [Toluene], [HClO4], [NaClO4], and [Acetic acid] on the rate of polymerization. The values of composite rate constant kkt/kpkoki for toluene (and substituted toluenes) was calculated by plotting [M]/Rp versus [M]?1. A very significant observation in the present study was that the plot of [M]/Rp versus [M]?1 gave a negative intercept, which seems to be a general observation for all inhibiting substrates. On the basis of the experimental data, it could be concluded that the benzyl radical obtained by hydrogen abstraction, and not a chain transfer, is responsible for the inhibition. 相似文献

One hundred ninety (190) serum samples and 52 control samples consisting of high risk individuals were screened for anti HCV antibody by 3rd generation ELISA test. The prevalence rate was found to be 1.57% in total but it was 2.12% in healthy voluntary blood donors. All were males between the age group of 21 to 40 years. All the control samples were found to be seronegative for anti HCV ab. 相似文献

IgM associated primary diffuse mesangial proliferative glomerulonephritis. 总被引:2,自引:3,他引:2 下载免费PDF全文
Twenty-three cases of IgM associated primary diffuse mesangial proliferative glomerulonephritis are presented. In 18, IgM was the sole localising host immunoglobulin, and it was the predominant globulin in five; C3 was also present in 18. Light microscopy revealed variable diffuse and global mesangial proliferation in all cases, with additional focal global sclerosis in 16, focal segmental sclerosis in 15, and small capsular crescents in seven. Material for electron microscopy was available from 19 patients; in 13, occasional intramesangial electron dense deposits were identified, and in 18 there were irregular, rather ill defined areas of increased electron density in mesangial regions. Clinically, 14 patients presented with the nephrotic syndrome, and nine had asymptomatic proteinuria. During follow-up, only 10 patients showed no change in renal function or improved; the remainder showed increasing hypertension and/or renal function deterioration and four developed end stage renal failure. It is suggested that IgM associated mesangial proliferative glomerulonephritis should be considered as a distinct clinicoimmunopathological entity. 相似文献

Ambient temperature related sleep changes in rats neonatally treated with capsaicin. PHYSIOL BEHAV 00(0) 000-000, 2004. The study was conducted on adult male Wistar rats, neonatally treated with capsaicin to destroy the peripheral warm receptors. The sleep-wakefulness was recorded for 5 h at an ambient temperature (T(amb)) of 18, 24, 30 and 33 degrees C on different days. The rectal temperatures (T(r)) of the rats were studied on exposure to 6 and 37 degrees C for 2 h to assess their thermoregulatory ability. The changes in the behavioral thermoregulation were assessed by noting the thermal preference of rats when they were placed in an environmental chamber with 3 interconnected compartments maintained at 24, 27 and 30 degrees C. Slow wave (SWS) and rapid eye movement (REM) sleep were decreased at 18 degrees C and increased at 30 degrees C, in control rats. There was a decrease in REM sleep and no change in SWS when T(amb) was raised from 30 to 33 degrees C. However, in neonatally capsaicin treated rats, sleep was increased even at 33 degrees C, though there was no significant change in sleep when T(amb) was increased from 18 to 24 degrees C. Capsaicin treated rats showed thermoregulatory deficiency at 37 degrees C but the thermal preference was unaltered in these rats. The results suggest that the central warm receptors can produce alteration in sleep at different T(amb), even in absence of peripheral warm receptors. The behavioral thermoregulation was unaffected in these rats, though their ability to defend the body temperature in warm environment was affected. 相似文献

Background
Arsenic in groundwater and its accumulation in plants and animals have assumed a menacing proportion in a large part of West Bengal, India and adjoining areas of Bangladesh. Because of the tremendous magnitude of the problem, there seems to be no way to tackle the problem overnight. Efforts to provide arsenic free water to the millions of people living in these dreaded zones are being made, but are awfully inadequate. In our quest for finding out an easy, safe and affordable means to combat this problem, a homeopathic drug, Arsenicum Album-30, appears to yield promising results in mice. The relative efficacies of two micro doses of this drug, namely, Arsenicum Album-30 and Arsenicum Album-200, in combating arsenic toxicity have been determined in the present study on the basis of some accepted biochemical protocols. 相似文献8.

In order to investigate the ameliorative potential of L-ascorbic acid on intensive swimming exercise induced testicular oxidative
stress, 18 Wistar male rats (age: 3 months, weight: 127.5 ± 5.3 g) were randomly divided into the following groups: (i) control
group (CG,n = 6); (ii) experimental group (EG,n = 6); and (iii) supplemented group (SG,n = 6). An exercise protocol of 3 h swimming per day, five days per week was followed for 6 weeks in EG and SG with no exercise
in CG. In SG, L-ascorbic acid was supplied orally at a dose of 25-mg/kg of bodyweight each day for 6 weeks. A significant
decrease (P < 0.05) was noted in paired testicular weights, epididymal sperm count, testicular Δ5, 3β-hydroxyseroid dehydrogenase, 17β-hydroxyseroid dehydrogenase, plasma levels of testosterone luteinizing hormone, follicle
stimulating hormone, prolactin, the numbers of preleptotine spermatocytes, midpachytene spermatocytes and stage 7 spermatids
of stage VII seminiferous epithelium cycle in EG when compared with CG. A significant elevation (P < 0.05) in plasma corticosterone and testicular content of malondialdehyde along with a significant reduction (P < 0.05) in glutathione, ascorbic acid, α-tocopherol, superoxide dismutase, catalase and glutathione-peroxidase, and glutathione-S-transferase
were noted in testes of EG compared with CG. No significant change was noted in final bodyweight or numbers of spermatogonia-A
among the groups. Furthermore, L-ascorbic acid supplementation restored the above parameters to the control level.
Conclusion It can be concluded that intensive swimming exercise induced oxidative stress causes dysfunctions in the male reproductive
system, which can be protected by L-ascorbic acid. 相似文献

The water-soluble glucan was obtained from Pleurotus florida fruit bodies by hot water extraction, ethanol precipitation, DEAE cellulose dialysis and Sephadex G-75 gel filtration. The
structural information of the glucan was achieved by chemical (hydrolysis, methylation, periodate oxidation) and spectroscopic
(1H and 13C) analyses, indicated a repeating unit built up of (1→6)-linked D-glucose. The following structure has been determined for
the repeating unit: →6)-α-D-Glcp-(1→ This fraction exhibited significant macrophage activity through the release of nitric
