It is now widely accepted that fatty liver disease is one of the commonest causes of cirrhosis and liver cell cancer (even in the absence of cirrhosis), in its own right as well as being an important cofactor for the progression of other diseases e.g. viral hepatitis. While much work has been done on developing non-invasive techniques for assessing liver disease, the liver biopsy remains the benchmark against which these tests have to be validated as well as providing information that cannot be obtained in any other way. This review describes the histological features that alcoholic and non-alcoholic liver disease have in common (e.g. fatty change, ballooning and Mallory–Denk bodies) as well as identifying those that are more characteristic of each of them (e.g. nuclear vacuolation in non-alcoholic fatty liver disease and a florid fatty liver hepatitis in alcoholic fatty liver disease). Recent developments in the assessment of the degree of fatty change are described. 相似文献

Sandalwood (Santalum album L.) is a fragrant wood from which oil is derived for use in food and cosmetics. Sandalwood oil is used in the food industry as a flavor ingredient with a daily consumption of 0.0074 mg/kg. Over 100 constituents have been identified in sandalwood oil with the major constituent being alpha-santalol. Sandalwood oil and its major constituent have low acute oral and dermal toxicity in laboratory animals. Sandalwood oil was not mutagenic in spore Rec assay and was found to have anticarcinogenic, antiviral and bactericidal activity. Occasional cases of irritation or sensitization reactions to sandalwood oil in humans are reported in the literature. Although the available information on toxicity of sandalwood oil is limited, it has a long history of oral use without any reported adverse effects and is considered safe at present use levels. 相似文献

Monoliths with chiral surface functionalization for enantioselective capillary electrochromatography
The state-of-the-art in CEC enantiomer separations with monolithic capillary columns is comprehensively reviewed. The various types of monolithic columns comprising in situ organic polymer monoliths, molecularly imprinted polymer (MIP) monoliths, silica monoliths and monoliths made from particles are discussed with a focus on materials’ synthesis, chemistry and properties as well as column aspects. Monolithic MIP-type porous layer open-tubular (PLOT) columns are treated herein as well. From this survey of the literature, the authors come to the conclusion that monolithic silica capillaries appear to become the preferred column type for CEC enantiomer separations of low-molecular drugs and other chiral pharmaceuticals or chemicals. 相似文献

OBJECTIVE: Health related quality of life (HRQL) has become an important outcome measure in the treatment of psychiatric disorders. This long-term observational study examined ziprasidone-induced improvement in satisfaction with HRQL in schizophrenia patients treated under real-world conditions. METHOD: Seventy schizophrenia patients with persistent symptoms or troublesome side effects were assigned to a 12-month, open-label, flexible-dose (40-160 mg/d), large-scale, naturalistic trial. Outcome measures were taken at baseline, 6, and 12 months, and included the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), severity of symptoms, distress, and side effects. RESULTS: Thirty-two patients fully completed the study protocol. Patients reported poorer general HRQL compared with healthy subjects. At the end of the study, significant improvement in general activity, and satisfaction with life was observed. The effect sizes for these changes were moderate (0.55, and 0.72, respectively). After Bonferroni correction for multiple comparisons improvement in satisfaction with general activity remained significant. No significant changes were noted in other Q-LES-Q dimensions. Improvement in general activity was associated with a reduction in the severity of symptoms and emotional distress, but was unrelated to the ziprasidone daily dose, side effect scores, and concomitantly prescribed antidepressants, anxiolytics, mood stabilizers, or antiparkinson drugs. CONCLUSION: This study indicates that ziprasidone treatment resulted in the improvement of the satisfaction with general activity that tended to increase over time, from month 6 onwards. This effect was associated with reduction in the severity of clinical symptoms, and emotional distress. 相似文献
