Clay materials of the quarry of bingerville (district of Abidjan) have been characterized by chemical analysis, X-rays diffraction, infrared spectroscopy and thermal analysis. These materials contain kaolinite (41% - 84%), illite (4% - 10%), quartz (14% - 27%), goethite (2% - 5%) and small amount of rutile (1%) that are not toxic minerals. They also contain some heavy metals which are beneficial to human biological activity (cobalt, copper, molybdenum, zinc) in tiny quantities. Some other heavy metals (lead, cadmium) which are considered as poisonous for human are present in very low content. The samples characterized by relatively fine grains are moderately crystallized. Their specific surface area varied from 26 to 43 m2·g—1. The mineralogical and physicochemical characteristics of these samples are like ones known for their healing properties. The consumption by internal way of studied materials, although it may be beneficial, requires a sifting to remove coarse grains (Φ > 2 μm) and a previous microbiological control.

This study reports on the safety and putative probiotic properties of bacillus amyloliquefaciens b-1895 and bacillus subtilis KATMIRA1933. According to the bacterial reverse mutation (Ames) test, cell-free supernatants of b. amyloliquefaciens b-1895 and b. subtilis KATMIRA1933 were not mutagenic. The two strains co-aggregated with Escherichia coli and Pseudomonas aeruginosa, and cell-free supernatants inhibited the growth of Streptococcus intermedius and Porphyromonas gingivalis. Endospores of b. amyloliquefaciens b-1895 and b. subtilis KATMIRA1933 were tolerant to 0.3% (w/v) bile salts and survived incubation for 4 h in MRS broth at pH 2.0 to 3.0. The ability of the two strains to produce antimicrobial compounds potentiates their application in health care formulations, personal care products, food and animal feed.

developments in laser diagnostic medicine

中国激光 1980年第Z1期 127-127页

作者： leon Goldman,M.d. director Laser Laboratory Medical Center University of Cincinnati director Laser Laboratory Medical Center University of Cincinnati

Significant developments have been made in laser diagnostic medicine since the earlyexperiments with laser micro-emission spectroscopy. Now, the field of laser diagnosticspectroscopy has been expanded tremendously with new techniques, especially with infraredlasers. Lasers are important in immunology now and for the future, especially with nephe-lometry and cell sorter techniques. Investigations have been started also on cardiovas-cular dynamics with laser, technology. Laser transillumination research continues forbreast cancer diagnosis. Laser communications, information handling and transmissionof x-ray pictures are additional applications for laser medicine. So now, laser diagnosticmedicine can be combined with laser surgery for the good of man, now and for thefuture.

在世界大部分养护管理水平较高的狗牙根草坪上,春季死斑病(全蚀病)(SdS)是一种非常严重的病害。本研究是为了确定(1)如果将原来巴感染春季死斑病的草坪放置在低温条件下,是否会降低狗牙根的再生性;(2)无病的和罹病的狗牙概枝条其再生性是否不同。从无病和以前曾受SdS侵染的小区中取样并放入温度为-3℃或-5℃的人工生长室内。在温室里,草样在光照下生长30d,然后再在黑暗条件下生长20d。每个阶段刈剪再生枝条,烘干并称重。结果表明,随低温逆境的加剧,***对狗牙根草坪的伤害加深。染病的狗牙概若处在低温下受害严重。田间受害多发生在12月份以后。但气温达到-5℃(时间≥1h)时间越早,SdS病对草坪的危害发生的也就越早。

目的评估A＋C群脑膜炎球菌多糖疫苗的安全性。方法以A＋C群脑膜炎球菌多糖疫苗为观察组，伤寒Vi多糖疫苗为对照组，按整群随机分层配对的原则，将研究现场分为108个组群，观察组和对照组各分配54个组。对两组同时建立接种反应监测系统，按统一表格和方法对两组的接种反应进行监测、记录，并进行流行病学调查。结果两组共接种34543人，其中A＋C群脑膜炎球菌多糖疫苗接种18167人，伤寒Vi疫苗接种16376人。A＋C群脑膜炎球菌多糖疫苗速发接种反应率为0．44‰，一般接种反应率为0．38％o；伤寒Vi疫苗速发接种反应率为0．79％，一般接种反应率为0．73％o；跟踪随访接种反应对象共1239人，其中接种A＋C群脑膜炎球菌多糖疫苗的771人，接种伤寒Vi疫苗的468人。接种后第1天，A＋C群脑膜炎球菌多糖疫苗组的局部反应发生率要明显高于伤寒Vi疫苗（X^2。=13．98，P=0．0002）；接种后第2—3天局部反应和全身反应的发生率，两组差异无统计学意义；两组各自接种人群和未接种人群发热发生率的差异无统计学意义，两组已接种人群的发热发生率差异也无统计学意义；两组均未发现严重反应。结论 A＋C群脑膜炎球菌多糖疫苗与伤寒Vi疫苗均可在不同年龄组人群开展大规模接种，局部及全身接种反应轻微，接种反应率低，有良好的安全性。
