Cardiopulmonary resuscitation is unlike any other medical intervention in its emotional impact. Its original use in reversible conditions has been replaced by its expected use in irreversible ones. The history of this transformation and its psychological concommitants are reviewed. New York State is unusual in having a ‘DNR’ law where resuscitation is the default position unless actively refused by patient or surrogate. The paradoxical genesis of this law, and its complex effect on a tertiary care hospital are described. Attention is focused on the emotional stresses on medical staff, and the extensive teaching program mounted by the institution's ethics committee to enable a positive adaptation. The difficulties inherent in surrogate decision-making are also reviewed. © 1997 John Wiley & Sons, Ltd. 相似文献

Fungi are a heterogeneous jumble coming together from three kingdoms of organisms. The True Fungi represent a kingdom of its own and are positioned closer to the Animalia than to the Plantae. At present the Fungi are divided into five Divisions. Species pathogenic for humans are found in the Divisions Zygomycota, Ascomycota and Basidiomycota. The Pneumocystidales are now classified in the Ascomycota. The Malasseziales are included in the Class Ustilaginomycetes. Essential characteristics for the classification of Fungi are derived from ultrastructure, chemistry, and more recently also from molecular biology of these organisms. None of these methods can stand for its own, all characteristics must be included. 相似文献

A case of rhinoentomophthoromycosis in a boy of 11 years is reported for its rarity in India. The various difficulties in its diagnosis and its response to treatment are discussed. Although the culture may be negative in these cases, the unmistakable histopathological picture is always confirmatory. 相似文献

肺癌是全球发病率和死亡率较高的恶性肿瘤。细胞从正常状态转变为肿瘤的过程中,细胞内蛋白质表达谱必然会发生一系列变化,肿瘤分子标记物就是细胞在非正常状态下产生的分子.以高通量结合生物信息学为特点的蛋白质组学分析技术可以从细胞整体水平上检测到这种变化近年来,为了降低肺癌的死亡率并提高其治疗效果,研究人员利用这一新的手段如利用激光捕获显微切割技术和双相凝胶电泳结合基质辅助激光解析电离飞行时间质谱(MALDI-TOF MS)和表面增强激光解析电离色行时间质谱(SELDI—TOF MS)寻找有效的肺癌标记物。本文对蛋白质组学技术在肺癌生物标志物研究中的应用作了综述。 相似文献

A 26-year-old man presented with a swelling in the right side of face and CT scan revealed a destructive tumor in the right maxilla. Tumor recurred within 5 years of its excision and histopathological examination revealed a clear cell odontogenic carcinoma. The rarity of this tumor, occurrence in maxilla and young age of the patient are some of the rare features which need documentation. The importance of its diagnosis and various differential diagnoses are discussed. 相似文献

Thalidomide, infamous for its teratogenic potential is now emerging as a therapeutic option for many disorders owing to its immunomodulant and anti-angiogenic effect. The demonstration of its ability to inhibit experimental angiogenesis in corneal micro-pocket assay in experimental animals led to the speculation that it might prove to be effective in certain angiogenesis dependent tumors. However, contrary to expectations, it failed to prevent tumor growth in certain animal models. The clinical study evaluating the effects of thalidomide in large number of patients suffering from refractory myeloma have shown encouraging results. Further trials are in progress to evaluate its effects in various other malignancies. In this review, various experimental and clinical studies demonstrating anti-angiogenic and anti-tumor effect of thalidomide are discussed with emphasis on its mechanism of action. 相似文献

Punarnavine (PN) has been isolated from the roots of Boerhaavia diffusa L. (Nyctaginaceae). It is an important medicinal plant with a vast historical ethnopharmacological background. Its identification resulted from the interrogation of ‘Punarnava’, a tribal medicinal product. The molecule exhibited its position as incipient anticancer therapeutic agent. The inhibition of NFκB, ATF-2, c-Fos, and CREB-1 are one of the underlying mechanisms of anticancer action along with modification of the immune system. These signalling molecules are upregulated in the cancer microenvironment. Punarnavine also modified the release of interleukins, i.e., upregulated IL-2, IL-7, IL-10, IL-12, IFN-γ, while downregulated IL-1β, IL-6, TNF-α, VEGF, and GM-CSF. Punarnavine has exhibited its anticancer potential in murine melanoma cell lines, breast cancer and its metastasis to lungs, liver, and lymph nodes by modifying apoptotic pathways and even suppressing metastatic genes like TIMP-1, TIMP-2, MMP-2, MMP-9 and VEGF. The pharmacokinetic and basic drug discovery properties are also discussed concerning in silico databases. This approach exhibited PN as a successful molecule for drug development. The drug-likeness, solubility, GIT absorption, drug metabolism, and bioavailability of PN are promising of its drug candidature and therefore need further detailed studies to ascertain its clinical potential. This article is a preview of the preclinical anticancer profile of Punarnavine, including the computational approach of its drug-like properties. 相似文献

Giant intrasacral schwannoma is a rare cause of a retrorectal mass in an adult patient. Only 21 such tumors have been reported. The diagnosis of this intraosseous nerve sheath tumor is heralded by its minimal symptoms in relation to its often striking radiographic findings and is verified by its unique morphology. Surgical resection is complex because of its anatomic location and propensity for local recurrence. The need for adequate tumor removal must be balanced against the preservation of nerve function. The presentation, diagnosis, and management of intrasacral schwannomas are reviewed, as exemplified in this case presentation and literature review. 相似文献

Genetic toxicity and potential carcinogenicity of taxol 总被引:4,自引:1,他引:3
The activity of the antineoplastic agent taxol depends uponits ability to inhibit tubulin disassembly in dividing cells.We show here that taxol gives a strong positive response inthe mouse bone marrow micronucleus assay. This is the firstreport of its genetic toxicity. The majority of antineoplasticagents are carcinogenic to humans, and the majority of humancarcinogens are active in the mouse bone marrow micronucleusassay. The present data therefore indicate a carcinogenic potentialof taxol for humans, which should be considered in the risk-benefitanalysis of its increasing clinical use. 相似文献
