The pine caterpillar is one of the most important pests of pine trees in China. Be-cause there are some disadvantages to apply chemical control of this pest, an urgentneed of using microbial methods as a supplementary measure is evident. The results ofthe preliminary test are very promising. The results are as follows: 1. The application of B. thuringiensis var. thuringiensis to control the pine cater-pillar seems to be very effective. In future it may develop into a new and powerfulweapon in pest control work. 2. The concentrations of the bacterial suspensions should be raised with the in-crease of larval instars. The range is approximately between 15×10~6--2.7×10~8 sporesper c.c. 3. High temperature resulted in a quick infection and death of the larvae. There-fore, the application of this method in June, July and August will give better results,though in cold and wet seasons, for example in March and April in central China, thecontrol is also effective. 4. The applications of B. thuringiensis var. thuringiensis with very dilute concentra-tions of chemical insecticides, such as 666, DDT and Diptrex, will give quicker andbetter results. This is a promising method. Dusting is valuelessly.

本文系应用苏云金杆菌(Bacillus thuringiensis var.thuringiensis)粉制剂防治马尾松毛虫(Dendrolimus Punctatus Walk.)的试验结果,试验表明此菌的致病力高,防治效果好,大有应用的前途。应用时,菌剂的浓度应随幼虫龄期的增加而递增,含孢子数的有效幅度为1,500-27,000万/c.c.死亡率可达90-100%。此菌如与稀浓度化学药剂(如666、DDT、敌百虫)混合使用,防治抵抗力较强的4-7龄幼虫,效果更好。

A strain of hydrocarbon-oxidizing bacterium isolated from local garden soil by enrichment culture method grew profusely in paraffin oil culture medium. All nalkanes of C_(12)-C_(18) as well as paraffin wax (m. p. 58-60℃) are easily oxidized by this microorganism, but their lower homologs and branched alkanes are quite resistant to the oxidation. The respiratory quotient of n-hexadecane and n-octadecane were found to be 0.44 and 0.47 respectively.The microbial oxidation of fatty alcohols (C_8-C_(18)) is similar to that of the corresponding alkanes. The rate of oxygen consumption of C_8-C_(18) fatty acids (10~(-3)M Na-salt) is nearly the same. These results may further support the hypothesis that the alkane oxidation most likely passes through the intermediate steps of the corresponding alcohol and fatty acid and finally enters the β-oxidation system.Some aromatic, naphthenic and other related compounds have also been tested.They showed either neglegible oxygen uptake or even suppressed the endogenous respiration.Azide, cyanide, iodoacetate, heavy metals(Hg~(++),Cu~(++), Co~(++))and α,α'-dipyridyl(5×10~(-5)to 5×10~(-3)M) inhibited the oxidation of n-hexadecane as well as n-hexadecyl alcohol to the extent of more than fifty per cent.The mechanism of the hydrocarbon oxidation by this bacterium and the enzyme systems possibly involved were discussed.

我们从土壤中分离得到一株烃类氧化菌,在石蜡油培养液中振荡培养,繁殖迅速,菌体呈亲油性。该菌能够氧化C_(12)、C_(14)、C_(16)、C_(18)等正烷和石蜡(熔点58—60℃)。正辛烷和正癸烷的氧耗率低于或等于内源。异烷似较难氧化。对正十六烷和正十八烷的呼吸商依次为0.44 和0.47。该菌对脂肪醇的氧化性能与烷类相似。C_(12)—C_(18)脂肪醇氧耗率相当高,低于正癸醇的醇类的氧化则不明显。C_8—C(18)脂肪酸钠盐(10~(-3)M)的氧耗率大抵相等。苯、甲苯(以上为饱和水溶液)、萘、蒽、菲、四氢萘、十氢萘、胆甾醇、胆酸钠(10~(-3)M)和高级脂肪醇硫酸酯的氧化都不明显或有抑制作用。各种浓度的迭氮化钠、氰化钠、碘醋酸、Hg~(++)、Cu~(++)、Co~(++)、a,a′-二联吡啶对菌氧化正十六烷和正十六醇有不同程度的抑制作用。根据以上结果,对菌体内烷烃的氧化途径及酶的性质作了某些推测和讨论。

Following this lead, seven active principles were isolated, all being derivatives of the dibenzo ( a, c ) cyclooctane system.

( 6 ) In recent years, Fructus Schizandrae was found to have therapeutic effects on certain chronic viral and chemical hepatitis, particularly in lowering SGPT. Following this lead, seven active principles were isolated, all being derivatives of the dibenzo ( a, c ) cyclooctane system. These principles were found to have a multiplicity of pharmacological activities on the liver in animal experiments.( 7 ) We have screened herbal preparations for antibiotic substances. For example, Salvia miltiorrhiza Bunge was shown to contain ingredients active against Strains of Staphylococcus aureus resistant to the commonly employed antibiotics. Ten active principles have been isolated and identified. We have also screened traditional Chinese and folk medicine for anti-inflammatory drugs. A peptide isolated from Musk has been shown to have inhibitory effect on inflammation of the ear in mice when given intraperitoneally or intravenously. The anti-inflammatory potency of this peptide was 6 times that of hydrocortisone on mg/kg basis.( 8 ) On changing the structure of scopoletin 6~morpholinoethoxy-7-methoxy-coumarin was synthesized. Pharmacological studies showed that this compound possesses not only asthmolytic action but also antiallergic action. In rats, the PCA and PLA reaction, degranulation and release of histamine from mast cells were all significantly inhibited by the injection of this compound. In order to find a drug selectively inhibitory to the activity of certain type of lymphocytes relative to the production of IgE, a preliminary study on the immunopharmaco-logy of a Chinese herb, Flores fonatanthus pumilus, was carried out.( 9 ) For antiparasitic drugs, several natural constituents with new struc-turs have been isolated from traditional Chinese and folk medicine,such as Ying-zhaosu ( an antimalarial ) , Hemerocallin and Cucurbitine ( antischistosomals ) and Toosendanin and Agrimophol ( anthelmintics ) .(10) Modern scientific techniques, such as microbial fermentation and tissue culture, were also applied to the excavation of effective drugs. For example, we have succeeded in cultivating Ganoderma and Armillaria mellea by a submerged cultivation method and cultivating Ginseng callus by a static culture method,
