维生素与矿物质：托起生命之重

一个体重70千克的成年人．如脱水后，只剩25千克．其中蛋白质12千克．脂肪7千克．碳水化合物3千克．其他包括维生素与矿物质3千克，可见，维生素与矿物质在人体中的含量是微乎其微的，然而维生素和矿物质却是人体生理功能重要的维护，据美国《科学导报》称．人体若没有维生素和矿物质．会在10天内死亡，另有资料显示．人体70％的疾病．是由于营养素失衡引起。

营养素补充剂老人需要吗

营养素补充剂是由一种或多种人体必需的营养素组成的,如维生素和矿物质.营养素补充剂中含有的维生素和矿物质同天然食物中含有的相同.一般情况下,人体是通过摄入食物来获得这些维生素和矿物质的,但营养素补充剂不是以食物为载体,而是以胶囊、片剂和口服液等剂型出现,但营养素补充剂不是药物,所以不能将营养素补充剂作为药物用于治疗疾病.

15种小零食 饭后吃一点

1葵花子，可以养颜。葵花子含有蛋白质、脂肪、多种维生素和矿物质，其中亚油酸的含量尤为丰富。亚油酸有助于保持皮肤细嫩，防止皮肤干燥和生成色斑。2花生，能防皮肤病。花生中富含的维生素B2，正是我国居民平日膳食中较为缺乏的维生素之一。因此有意多吃些花生，不仅能补充日常膳食中维生素B2之不足，而且有助于防治唇裂、眼睛发红发痒、脂溢性皮炎等多种疾病。     

甲亢的骨质与矿物质代谢变化 附100例观察与文献复习

甲状腺机能亢进(简称甲亢)是比较常见的一种内分泌疾病,除表现有典型的高能代谢率症候群、甲状腺肿及/或突眼外,一些长期患者还会合并骨质疏松等变化与矿物质代谢紊乱,且与甲状腺的功能及活性维生素D代谢产物有关。我们于1978～1982年共观察了100例住院甲亢患者的骨质变化,及其     

Degraded and undegraded carrageenans and experimental gastric and duodenal ulceration

The prevention of histamine-induced gastric and duodenal ulceration in the guinea-pig has been examined using a series of undegraded and degraded carrageenans. Undegraded carrageenans were active at lower doses than degraded carrageenans. The high viscosity of the undegraded carrageenans in solution prevented their use in larger doses. Degradation of carrageenan without serious loss of sulphate, gives a product which allows the dose to be increased to an extent that its effect more than offsets the slight loss in activity caused by the degradation. No single feature of carrageenan structure can be related to anti-ulcer activity although degradation, and hence reduction of molecular size, generally reduces activity. Sulphate contents over 30% have little apparent effect on activity; κ-carrageenans were not consistently different in anti-ulcer activity from Λ-carrageenans. This contrasts with the antipeptic activity of carrageenans where κ-carrageenans are less active than their Λ-counter-parts. As with antipeptic activity, the degree of anti-ulcer activity is probably determined by a combination of structural features which includes molecular size and polyanionic properties.     

Affective and Anxiety Disorders and Alcohol and Drug Dependence:

Depression and anxiety frequently coexist in patients with substance use disorders. This clinically-oriented article examiens the relationship between these conditions and emphasizes data showing that substances of abuse can cause signs and symptoms of both depression and anxiety. These substance-related syndromes appear to have a different course and prognosis than uncomplicated, independent anxiety and major depressive disorders, and clinicians should consider the role of alcohol and other drugs in all patients presenting with these complaints. The authors will also outline an approach for diagnosing and managing patients with the combination of a substance use and depressive or anxiety disorder.

Glucosidase and fucosidase inhibitors and Advances in nucleosides and nucleotides.

The American Chemical Society Symposium "Glucosidase and fucosidase inhibitors" took place on 1 April 1998 and was organized by Professors Zbigniew J Witczak (UConn, School of Pharmacy, CT, USA), Kuniaki Tatsuta (Waseda University, Tokyo, Japan) and Waldemar Priebe, MD (Anderson Cancer Center, University of Texas, USA). Professor Witczak provided introductory remarks including the status of existing glucosidase inhibitors, and chaired the morning session, which consisted of six lectures. The symposium was well received, and was particularly attractive for those interested in networking, as attendance was about sixty. In addition, some participants and attendees presented posters on the subject during the regular poster session organized by the Division of Carbohydrate Chemistry.
