碘化油在防治大鼠试验地方性甲状腺腫上的效用

地方性甲状腺腫,俗叫鹅喉,古称癭,是一种由于食物及饮水中的碘不足人体需要所引起的疾病。内陆高原山区地带的水土中往往缺乏碘,所以这些地区出产的食物也缺乏碘。我国的西南(如云南、广西北部、贵州西南部及四川西部),西北(如青海、甘肃、宁夏及内蒙古南部),东北(如河北北部、热河及辽宁西部),以及山东南部及湖南东南部居民多患地方性甲状腺腫。这样看来,这种病在我国发生的地域甚广,被害的人民众

Garlic (Allium sativum) and onion (Allium cepa): a review of their relationship to cardiovascular disease

Garlic and onion have been used for millenia in the traditional medical practice of many cultures to treat cardiovascular and other disorders. Both Allium species, their extracts, and the chemical constituents of these plants have been investigated for possible effects on cardiovascular disease risk factors--both definite (hyperlipidemia, hypertension and hyperglycemia) and suspected (platelet aggregation and blood fibrinolytic activity). Action of these Allium species on blood coagulability is more clearly defined than their effect on the other risk factors. While many of the studies have serious methodological shortcomings, there is some evidence to suggest that use of certain formulations of garlic and/or onion is accompanied by favorable effects on risk factors in normal subjects and in patients with atherosclerotic disease. The possibility of toxicity resulting from acute and chronic ingestion of large amounts of these plants or their extracts is unresolved. Accordingly, further clinical and epidemiological studies are required before the role of these plants in the prevention and control of cardiovascular disorders is understood and can be realized. Additional research in this area is recommended.     

Bioavailability of selenium from selenium-enriched green onions (Allium fistulosum) and chives (Allium schoenoprasum) after 'in vitro' gastrointestinal digestion

Three sample preparation methods--proteolysis to determine the initial species distribution, and an in vitro gastric and gastrointestinal digestion to assess the bioavailability of selenium--were applied to extract the selenium from selenized green onion and chive samples. Ion exchange chromatography was coupled to a high-performance liquid chromatography-ICP-MS system to analyze the selenium species of Allium samples. The difference in the selenium accumulation capability of green onions and chives was significant. Chive accumulated a one order of magnitude higher amount of selenium than did green onion. After proteolysis of both types of Allium plants, high amounts of organic selenium species such as MeSeCys, SeCys2 and SeMet became accessible. In the case of Se(VI)-enrichment, selenate was the main species in the proteolytic extract. After simulating the human digestion, the organic species were just slightly bioavailable compared with the results from proteolysis. The inorganic selenium content of the selenized samples increased significantly and SeOMet could be detected from the extracts. As an effect of the significant pH change between the gastric and the intestinal tracts, two oxidation processes took place: selenite oxidized to selenate, while SeMet oxidized to SeOMet.     

Allium sativum (garlic) and atherosclerosis: A review

This paper reviews research published in recent years concerning the effects of garlic on lipid metabolism and atherosclerosis. In both animal and human studies, components of garlic have been shown to lower cholesterol and triglyceride levels. Garlic has also been shown to change blood lipoproteins and to affect coagulation parameters. The available data suggest that garlic may be of value in either the prevention or treatment of atherosclerotic diseases. Further research in this area is warranted.

Allium vegetable intake and risk of acute myocardial infarction in Italy

Background  Interest in potential benefits of allium vegetables has its origin in antiquity, but the details of these benefits are still open to discussion. Only two epidemiological studies considered the relation between dietary intake of allium vegetables and cardiovascular diseases. Aim of the study  To provide further information we analysed the relationship between onion and garlic intake and acute myocardial infarction (AMI). Methods  We used data from a case–control study of 760 patients with a first episode of non-fatal AMI and 682 controls admitted to the same hospitals. Information was collected by trained interviewers using a validated and reproducible food-frequency questionnaire. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were obtained after allowance for recognized confounding factors. Results  Compared with non-users, the ORs of AMI for subsequent categories of onion intake were 0.90 (95% CI: 0.69–1.21) for <1 portion of onion per week and 0.78 (95% CI: 0.56–0.99) for ≥1 portion per week. For garlic, the ORs were 0.84 (95% CI: 0.66–1.09) for intermediate and 0.94 (95% CI: 0.68–1.32) for high use, compared with no or low use. Conclusion  The current study, the first from Mediterranean countries, suggests that a diet rich in onions may have a favourable effect on the risk of AMI.     

Fructans and major compounds in onion cultivars (Allium cepa)

The moisture, ash, protein, Brix degree, glucose, fructose, sucrose, total fructans and total sugar, total and insoluble fibre contents were quantified in five traditional onion cultivars from Tenerife (Guayonje, San Juan de la Rambla, Carrizal Alto, Carrizal Bajo and Masca) and a commercial cultivar (Texas Early Grano 502). The ratio between insoluble and soluble dietary fibre (IDF:SDF) and between glucose and fructose (G:F) were also determined. There were differences between cultivars in all the studied variables except for the IDF:SDF ratio. Carrizal Bajo and Carrizal Alto presented the highest moisture content and lowest protein, fibre, sugars and total fructans contents. In contrast, the Texas cultivar had the highest total and insoluble fibre and glucose contents, the Masca cultivar had the highest ash and protein contents, the Guayonje cultivar had the highest fructose and total sugar contents, and the San Juan de la Rambla had the highest Brix degree and total fructan contents. Significant differences in many of the parameters analyzed were observed between the two seed origins for the Guayonje and San Juan de la Rambla cultivars. Many correlations were observed between the parameters analyzed. The onion samples tended to be classified according to the cultivar when applying discriminant analysis.

Effects of typheramide and alfrutamide found in Allium species on cyclooxygenases and lipoxygenases

Typheramide (N-caffeoyltyramine) and alfrutamide (N-feruloyltyramine) are phenylpropenoic acid amides found in plants. In this article, typheramide and alfrutamide were isolated from Allium sativum (garlic) and Allium fistulosum (green onion), their chemical structures were confirmed using nuclear magnetic resonance spectroscopic methods, and the potential effects on cyclooxygenases (COXs) (COX 1 and 2) and lipoxygenases (LOXs) (5- and 15-LOX) were investigated. Typheramide and alfrutamide inhibited COX 1 by 74% (P?相似文献
