含中草药成分造纸法再造烟叶的制备

介绍了一种造纸法含中草药成分再造烟叶的制备工艺。该工艺应用了类似造纸的原理,将中草药与烟草混合萃取后,取其纤维制成高填充值的纸叶,萃取液经低温真空浓缩处理后浸涂到该纸叶上。该工艺扩大了中草药的用药范围,有效成分可较灵活控制,提高了中草药原料的利用率。制成的含中草药成分再造烟叶充分保留了不溶性有效药用成分,与烟香谐调,安全性好,同时具有较高的填充值,可以明显降低卷烟的制造成本。

Quality of life and breast cancer survivors. Psychosocial and treatment issues

Vitamin A deficiency is one of the most common nutrient deficiency syndromes in children from developing countries. It is also correlated with the increased severity and incidence of certain infections. Until recently, vitamin A research was focused on preventing xerophthalmia and blindness in Third World Countries and on the development of synthetic retinoid molecules, with lower toxicity than vitamin A, for the treatment of skin diseases. However, there has been a major shift of emphasis in the last five to ten years. There is a risk of death from xerophthalmia, primarily from complications with infectious diseases. Intermittent treatment with the very large doses of vitamin A prescribed to combat blindness was shown to be effective. This suggests that vitamin A may affect specific elements of the immune system. High-dose vitamin A supplements have been given, at widely-spaced time intervals, to preschool children in communities where vitamin A deficiency causes xerophthalmia and blindness, over the last 20 to 30 years. A strong correlation between mortality and xerophthalmia was identified. Death then became the principal outcome measured because it was easier to detect than xerophthalmia, particularly in large clinical trials in high risk regions where clinical expertise was minimal and vitamin A deficiency was a commoner cause of death than blindness. Other, food-based approaches to the treatment and prevention of vitamin A deficiency, involving foods naturally rich in retinol or carotenoid, or foods artificially fortified with these nutrients, should be developed.
