Prostate Specific Antigen (PSA) has emerged as the most applicable and important tumor marker for carcinoma prostate. In the
present study PSA was determined in serum of healthy subjects, patients of benign prostate hypertrophy (BPH) and Carcinoma
Prostate (Ca−P) to evaluate its diagnostic efficiency in day to day management of prostate cancer patients and in differentiating
patients of early prostate cancer from those with BPH. Receiver operating characteristic curve (ROC) revealed 2 ng/ml and
10 ng/ml cut off serum PSA level for BPH and untreated carcinoma prostate patients (Ca−P). An extremely significant increase
(P<0.0001) was observed in mean PSA concentration in BPH patients and adenocarcinoma prostate patients when compared to healthy
males. Clinical relevance of PSA was highlighted by a case study of cancer patient prior to any therapy till death. 相似文献

The goal of this study was to determine the stability of Total Prostrate Specific antigen (PSA-T) and Free Prostrate Specific
Antigen (PSA-F) in archival serum stored at 4°C and −20°C and subjected to temperature shift due to interruption in power
supply. Our study showed that PSA-T was stable up to 285 days and PSA-F was stable for 158 days under these conditions. Since
power supply interruption is an unavoidable problem in developing nations, our study has implication on the validity of measurement
of PSA-T and PSA-F in serum that was not properly stored due to emergency situations and for certain types of retrospective
studies. 相似文献

A series of polysulfonamide （PSA）/TiO 2 modifier nano-composite films were successfully prepared by in-situ polymerization at a low temperature based on 4, 4-diaminodiphenylsulfone and terephthaloyl chloride in the common solvent N, N-dimethylacetamide （DMAc）. It was shown that the nano particles were well dispersed in the polymer substrate. Mean-while, PSA/TiO 2 /modifier composites exhibited good UV-resistant properties and mechanical properties. In addition, the composites’ heat stability improved. These prepared composites are promising in preparing spinning solution and might have potential application in heat-resistant fiber. 相似文献

As a special and extensive type of advertising, public service advertising(PSA) has become an important cultural phenomenon. Same as commercial advertisement, PSA can also convey cultural values. Out of similar purposes, however, PSA for disasters between China and other western countries contain many differences. Aiming to reveal the cultural differences, this paper undertakes the analysis of PSA for disasters of China and other western countries from the perspective of inter-cultural communication. 相似文献

The serum PSA is universally accepted as the useful and clinically relevant tumor marker for monitoring therapy and identifying
early recurrence in patients of carcinoma prostate throughout the world. However, application of serum PSA is limited to screening
for early adenocarcinoma prostate among males above fifty years of age.
Serum PSA concentration varies from one population to another in different parts of the world. Many groups of workers have
selected 4 ng/ml of serum PSA as upper limit of normal range without giving due consideration for age specific increase in
serum PSA. There is no single report available on normal decade wise age specific reference intervals for serum PSA in Indian
males.
The present study is undertaken to establish age specific reference intervals in healthy Indian males from 20–89 years belonging
to subpopulation of Andhra Pradesh from South India. Our results revealed lowest concentration of 95 percentile serum PSA
in Indian males compared to other populations globally. Contrary to this, healthy Afro Americans were found to have highest
concentration of serum PSA compared to all other populations. 相似文献

公益广告是人类智慧的象征,烙有各国文化的痕迹。很多学者已经针对广告做出了系列研究,但是对公益广告的跨文化研究与比较却少之又少。因此,笔者决定从中西方文化差异方面来对中西的公益广告进行比较与研究,以期对中西文化的跨文化研究作出微薄贡献。 相似文献

The reintroduction of universal free admission to the government-sponsored museums is often cited by politicians and commentators as one of the principal cultural policy achievements of the current Labour administration. Both in terms of increasing the total number of visits to the sponsored museums and in encouraging new visitors from priority groups the policy has been a demonstrable success. The complexities of the data generated in support of free admission have hitherto, however, gone largely unexamined. This article therefore explores the ways in which government has gone about measuring the impact of its free admission policy. It traces the history of free admission to museums and galleries as a concept, before setting out the background to the reintroduction of universal free admission to those museums sponsored by the Department for Culture, Media and Sport (DCMS) that had introduced charging in the 1980s and 1990s. It then considers ways in which the impact of the policy can be measured, through use of the data generated by the 23 performance indicators used by DCMS in the funding agreements that it has with each of the museums. The article then considers the various factors that need to be taken into consideration in any assessment of the impact of the free admission policy, including the effect of new capital investment. The article concludes by suggesting that further work is needed to isolate the precise impact of free admission, particularly on attracting new audiences to museums and galleries. 相似文献

目的研究前列腺特异性抗原（Prostatespecific antigen,PSA）检测用于前列腺癌筛查的临床价值。方法收集1044例住院人群PSA检测资料与前列腺癌检出率进行统计分析。结果 1044例中有16.57%（173例）血清中PSA有不同程度增高,最高值在300 ng/ml以上,且随年龄增大其增高程度及增高比例逐渐增加;前列腺癌检出率为0.957%,在50~79岁人群检出率为6.4%。结论前列腺特异性抗原检测用作前列腺癌的常规筛查临床价值不高,用于高危人群筛查有较高的临床价值。 相似文献
