麝香鼠养殖商机无限

麝香鼠俗名青根貂。是一种产香、肉、皮毛药用、保健化妆品高效经济动物。与麝鹿齐名,过去生产的中药保健品、化妆品所需的动物香料都是靠麝鹿分泌的麝香和灵猫分泌的灵猫香。现在麝鹿已成频于灭绝的动物,其麝香原料及产品已被禁用。灵猫不仅繁殖难、饲养难,灵猫香极少,且杂质较多,在应用范围上受到很多限制。而麝鼠香则自然而然地成频于枯竭的动物香料的重要补充。麝香鼠原产于北美洲,后引进原苏联和我国。

特种畜禽养殖的前景分析

特畜养殖品种如梅花鹿、马鹿、小尾寒羊、肉狗、肉兔、小型猪、香猪、麝鼠、海狸鼠、果子狸、竹鼠、蛇、蛤蚧等在我国已经形成一定规模。梅花鹿、马鹿受国外市场冲击,使我国自产的鹿茸及其制品销售受阻。因此,不宜盲目发展。小型猪、香猪、麝鼠、海狸鼠、竹鼠等养殖品种由于前几年被炒种者炒作，挫伤了养殖者的养殖积极性，消费市场和加工相对滞后，全国存量逐渐减少，预计年养殖前景相对看好。果子狸属于国家保护动物，目前多为暂养，不宜大量发展。过去几年肉鸽一直看好，市场平稳，肉鸽养殖趋向稳中有升，

高山栲水提液对云南松种子发芽的化感效应

为了解混交树种高山栲对云南松的化感作用,用高山栲各器官水提液对云南松种子的发芽进行处理。结果表明,高山栲鲜叶、枝干、树皮、树根,枯落叶水提液对云南松种子的发芽和芽的生长均有一定的影响。所有样品的水提液均表现出在高浓度下对云南松种子发芽和芽的生长有明显抑制作用,随着水提液浓度减小,抑制作用减弱、消失甚至转变为促进作用的规律;其中枝干和鲜叶水提液对云南松种子发芽和芽的生长作用强度最大;发芽效果不同指标对高山栲各器官水提液作用的敏感性次序是:鲜重>根长>发芽率>胚轴长。说明在营造云南松和高山栲混交林时,高山栲比例适当减小将有利于云南松的天然更新和生长。     

Anti-inflammatory activity of Dalbergia sissoo leaves

The possible anti-inflammatory activity of the 90% ethanolic extract of Dalbergia sissoo leaves (DSELE) was studied in different models of inflammation in rats after oral administration at doses of 100, 300 and 1000 mg/kg. DSELE significantly inhibited carrageenin, kaolin and nystatin-induced paw oedema, as well as the weight of granuloma induced by a cotton pellet. It also inhibited dye leakage in acetic acid-induced vascular permeability test in mice. DSELE was devoid of ulcerogenic effect on the gastric mucosa of rats in acute and chronic tests. In acute toxicity studies, it was found to be safe up to 10.125 g/kg, p.o. in the rat. It was concluded that the D. sissoo leaf extract possessed significant anti-inflammatory activity (in acute, sub-acute and chronic models of inflammation) without any side effect on gastric mucosa.     

Intestinal antiinflammatory activity of a lyophilized infusion of Turnera ulmifolia in TNBS rat colitis

Turnera ulmifolia is a plant popularly known in Brazil and South America as chanana. Some species of Turnera are widely used in folk medicine for different types of inflammatory diseases. In this study, the preventive intestinal antiinflammatory activity of a lyophilized infusion obtained from the aerial parts of T. ulmifolia was tested in the trinitrobenzenesulphonic acid (TNBS) model of rat colitis. The results obtained revealed that pretreatment to colitic rats with the extract, at 250 and 500 mg/kg, significantly attenuated the colonic damage induced by TNBS. This beneficial effect was associated with an improvement in the colonic oxidative status, since the infusion prevented the glutathione depletion that occurred as a consequence of the colonic inflammation. On the other hand, this antioxidant activity was confirmed in in vitro studies. In conclusion, the preventive effect exerted by the lyophilized infusion of T. ulmifolia in the TNBS model of rat colitis is probably related to its antioxidant properties, due to its flavonoids content.     

Antiinflammatory activity of the aqueous leaf extract of Byrsocarpus coccineus

The antiinflammatory effect of the aqueous leaf extract of Byrsocarpus coccineus was evaluated using the carrageenan and egg albumin induced rat paw edema, xylene induced mouse ear edema and formaldehyde induced arthritis inflammation tests. The extract administered orally at doses of 50, 100, 200 and 400 mg/kg b.w produced a significant (P<0.05) dose dependent inhibition of edema formation in all four methods used. The results obtained suggest that the aqueous leaf extract of B. coccineus is endowed with effective antiinflammatory activity mediated via either inhibition of phospholipase A(2) (PLA(2)) activity or cyclooxygenase cascade and by blocking the release of vasoactive substances (histamine, serotonin and kinins). These findings seem to justify the use of the plant in traditional African medicine in the treatment of inflammation, including arthritic conditions.

越南的林业

越南地理位置优越,气候适宜,土壤肥沃,有较优良的林木适生环境和较丰富的森林资源。但是由于60、70年代的战争破环和80年代以来的大面积森林砍伐,原始天然林已大面积减少。近年来越南把严格保护天然林,大力发展人工林作为林业的首要任务,使林业生产有了较大改观。本文主要介绍越南森林资源概况、自然保护区建设、造林以及林业机构等方面的情况。     

Winter wheat pests and their natural enemies under organic farming system in Slovakia: Effect of ploughing and previous crop

Organic farming system of winter wheat was investigated in Solvakia over three years, 1995–1997. The system was carried out on a small scale (four plots of 50 m²). Neither pesticides nor inorganic fertilisers were applied. Effect of two treatments, ploughing and previous crop, on the community of pests and natural enemies was surveyed. There were two types of ploughing (shallow and deep) made in autumn before sowing. As previous crops, silage-maize and alfalfa were used each season. The effect of all factors was analysed by multivariate method, redundancy analysis (RDA) and Monte Carlo permutation to assess statistical significance. During three years, 37 taxons of pests and 27 taxons of natural enemies were recorded. The results of RDA showed that the community of insects (pests and natural enemies) was mainly influenced by temporal variation. The highest abundance of all insects was observed in 1996. The effect of the two treatments on the community of pests and natural enemies was less obvious. Pests were found to be significantly more influenced by ploughingthan by previous crop. Most of pests occurred more abundantly on plots with shallow ploughing and on plots after maize. Abundance of natural enemies were, however, significantly affected by previous crop. Majority of them were more abundant on plots after maize than after alfalfa. Ploughing had only marginally significant effect on natural enemies that were more abundant on shallow ploughed plots. Both ploughing and previous crop had only negligible effect on species diversity of natural enemies.
