“北参南七”说法的由来

正人参作为我国名贵中药材之首,有着家喻户晓的知名度,被称为百草之王。但人们对人参家族的成员,与人参并称"北参南七"的三七却知之甚少。其实,三七和人参都是五加科人参属植物,是名副其实的亲兄弟。现代植物学研究证明,三七与被誉为百草之王的人参、西洋参是近亲,它们同属五加科人参属植物,并都以皂苷为主要有效成分。但它们既有相同之处,又有明显的不同点,区别在于药用价值和药理作用的不完全相同。

人参化学成分和药理作用研究进展

人参在《神农本草经》中被列为上品药物,具有"多服久服不伤身、轻身益气不老延年"的作用。其在中医药临床领域中具有悠久的历史,然传统研究进展十分缓慢,属于古代朴素研究阶段。由于现代科技的飞速发展,对人参的研究也得到了突飞猛进的突破。查阅国内外人参在神经系统、抗肿瘤、心脑血管免疫功能等方面的研究资料,并对其进行分类概述。总结了人参的药理作用,为进一步揭示人参的药理作用提供科学依据。

Amylolytic activity in stored potato tubers. 1. Estimation usingp-nitrophenyloligosaccharides

Summary Methods for the estimation of amylolytic activity are reviewed. A procedure for the routine extraction of amylolytic activity from freeze-dried powder prepared from potato tubers is described. The extraction medium is buffered at pH 7.0 and contains glycerol, dithiothreitol, calcium chloride and the non-ionic detergent, nonidet P-40. α-Amylase activity and exoamylolytic activity were estimated in crude extracts of potato tubers using the substrates, blockedp-nitrophenyl-maltoheptaoside andp-nitrophenyl-maltopentaoside respectively. These substrates are included in kits supplied by Biocon, (UK) Ltd to measure the α- and ?-amylase activity in cereals. The validity of using these kits for the determination of α- and ?-amylase activity in potato tuber tissue is discussed.     

The origin and distribution of the golden nematode and its potential in the U.S.A.

Potato cyst-nematodes,Globodera pallida andG. rostochiensis (golden nematode), and their preferred host, the potato, originated in the Andes of South America. Both were introduced into Europe from the Andean region, the potato about 1570 and the nematode nearly 300 years later. Potato cyst-nematodes are believed to have been introduced into Europe in the 1850’s along with potato collections from the Andes for use in breeding for late blight resistance, but the nematodes went unnoticed until 1881. Since that time the nematodes have spread to virtually everywhere that potatoes are grown, as one or both species have now been reported from 47 countries. It is believed that the golden nematode was introduced into the U.S.A. from Europe on military equipment brought back after the First World War to Long Island, NY, but the nematode was not recognized until some 20 years later. Yield losses in countries with general infestations of potato cyst-nematodes are probably 9% or more; the potential for losses is greatest in countries where average yields are greatest, such as the U.S.A. Good resistance to the pathotype of the nematode that occurs in the U.S.A. is commercially available. If all potatoes grown in the U.S.A. contained this resistance, further spread would be restricted and the golden nematode could perhaps be eliminated from the U.S.A.; but the present supply and diversity of resistant varieties are insufficient for the total potato acreage. Restricting spread of the golden nematode in the U.S.A. minimizes costs borne by growers and government agencies in dealing with the pest. At present, the most promising approach to restricting spread is through management systems developed for keeping nematode densities below the critical level above which spread will occur. If the golden nematode is to be contained, management systems must eventually be applied to all potato acreages. Increased research effort is needed to develop resistant varieties, resistance to a broad range of pathotypes, nematode management systems, and biological control     

Fiber formation model for electrospinning. II. Stable jet voltage

The major concern in electrospinning process is the occurrence of jet formation. In order to study physical properties of the solution and process parameters, stable jet voltage model is developed to predict the stabilized jet in electrospinning. Break-up frequency model, that predicts behavior of drop breaking, is the theoretical background for stable jet voltage model. This newly developed model based on the previous work gives a clue to produce stable nano thickness fibers and the results are compared with the experimental data by PVP electrospinning. The result of stable jet voltage modeling shows that surface tension is the most important factor and molecular weight and concentration are both negligible for surface tension of solutions. Surface tension of the solution depends on the types of solvent. Therefore, surface tension of solution has different values of stable jet voltage. The stable jet voltage model that predicts the most similar experimental value is SIC hemispherical model under force mode.     

INTERNATIONAL EXCHANGE OF HERBAGE SEEDS AND THE O.E.C.D. HERBAGE SEED SCHEME

The use of the correct variety has an important influence on the economic use of sown grassland. The production of seed must be done in such a way that the essential characters of varieties are preserved. The O.E.C.D. Herbage Seed Scheme provides a sound basis for seed production, and has made possible the wider exploitation of good seed growing areas. The technical basis for some of the rules is discussed. It is concluded that in the 8 years in which the Scheme has been operating there has been a significant change in the pattern of seed use with a greater emphasis on the better varieties.     

A review of the biology and control of selected weed species in the genus Oxalis: O. stricta L., O. latifolia H.B.K. and O. pes-caprae L.

This review considers the distribution, weed problems, biology and control of Oxalis stricta, O. latifolia and O. pes-caprae. The rhizomatous O. stricta is a persistent seed-producing weed which invades horticultural crops in North America. Chemical control is generally most effective in situations where soil-applied residual herbicides can be used; in turfgrass however, foliage-applied herbicides provide suppression only. O. latifolia is widely distributed in a range of annual and perennial crops growing in temperate and tropical locations. This pernicious perennial weed reproduces exclusively by asexual structures, underground bulbs, stolons and tubers. The complexities of the perennating system have rendered ineffective a wide range of herbicide families as a means of restricting the spread of O. latifolia. Similarly, cultural methods of control have not been successful. O. pes-caprae also grows and perennates from bulbs. This weed is essentially a problem in cereal crops in Southern Australia and Mediterranean fruit orchards. Cultural and chemical control difficulties and inadequacies are similar to those in O. latifolia. Future research strategies involving weed physiology, herbicide action and cultural control including biological control are discussed in relation to obtaining improved control methods for the selected Oxalis species.     

The breeding system of Ornithopus sativus Brot. subsp. sativus

Genetic traits within Ornithopus sativus Brot. make it suitable for breeding as a forage legume in agriculture. The breeding system of O. sativus must be understood to stabilize valuable traits once developed. Hybridization between white‐flowered and pink‐flowered genotypes of O. sativus revealed the white flower colour to be inherited recessively to pink, while early flowering showed genetic dominance over late flowering (d = 0.5). The pink flower colour was always associated with red pigmentation on seedling hypocotyls, which provided a pragmatic aid in the selection process. Pollination of O. sativus is largely autogamous, but examination of hypocotyl colour of seedlings from white‐flowered trap plants placed among pink‐flowered plants in a sward indicated a xenogamic cross‐pollination rate of 25% is possible. This significant level of cross‐pollination revealed opportunities for breeding desirable traits within the species, while providing a warning that shifts in population structure could occur in response to selection pressure.

GRASSLAND RECORDING. IV

The traditional method of calculating field output by the utilized-starch-equivalent (U.S.E.) system is compared with a recommended simpler and quicker method. The concept of calculating a U.S.E. factor is introduced and forms the basis for the new method. A monthly U.S.E. factor is used, in conjunction with monthly cow-day (CD.) records to calculate U.S.E. Savings of at least 50% may be expected. Agreement between the two methods is very close and the more seasonal nature of the calculation for sheep and non-milking cattle under the new method may be preferable.
