  food patch
In a thin layer in the middle of the halocline, we inserted a food patch that consisted of 0, 2500, 5000 or 10?000 T.
      
The presence of a food patch had a pronounced effect on the vertical distribution of larvae.
      
This effect depended upon the algal density of the food patch and varied with dietary conditioning.
      
The greater number of algal cells in the digestive tracts of larvae from treatments with a food patch than in those without a patch confirmed that larvae were feeding on the microalgal cells of the patch.
      
To our knowledge, this is the first study to experimentally show an aggregative behavioural response of invertebrate larvae to a food patch.

A new method for the biological assay of vegetable purgatives based on the numbers of wet faeces excreted by groups of mice after dosing is described. The relation of the number of wet faeces per group of mice to the logarithm of the dose was found to be linear. A cage has been specially designed for this assay and it has been found advantageous to incorporate a definite proportion of water in the diet during test. 40 mice divided equally into 4 groups were used in each assay. 2 groups received the standard...

A new method for the biological assay of vegetable purgatives based on the numbers of wet faeces excreted by groups of mice after dosing is described. The relation of the number of wet faeces per group of mice to the logarithm of the dose was found to be linear. A cage has been specially designed for this assay and it has been found advantageous to incorporate a definite proportion of water in the diet during test. 40 mice divided equally into 4 groups were used in each assay. 2 groups received the standard preparation and the other 2 groups received the test preparation. The standard deviation of a single determination based on 9 such assays was estimated to be 15.7 per cent. For rhubarb and its preparations, a“6-point”assay is advocated. With suitable restric-tion in the design of the assay, it is possible to calculate the potency by simple methods. Powdered crude drugs are used as laboratory standards in the assay of senna and rhubarb. The doses of cascara bark required to produce distinctive responses are too inconveniently large to be administered in suspension. It was found possible to use a potent extract of cascara in place of the powdered bark as a laboratory standard. Examples of the assay and the subsequent calculations are given. The method described is not only convenient in use but also gives a comparatively high degree of accuracy. The method has been successfully applied to senna leaf, senna fruit, rhubarb, cascara sagrada and extracts and commercial preparations made from these drugs, pure glycosides(sennosides A and B) and pure anthracene compounds(aloe emodin and aloe-emodine anthranol).

(1)本文详述植物性泻药的一种新的生物测定法,此法係用小白鼠在服药后所排出的濕粪数为基础,以定泻药的效价。(2)小白鼠服药後所排出的湿粪数与剂量指数的关係经证明为一直线。(3)本法所用鼠笼係特别设计,并证明在饲料内加入一定量的饮水,具有多种优点。(4)番泻效价的测定,每次用小白鼠4组,每组10只。2组给与标准品,另外2组给与试验品。根据9次试验的结果,试验的标准差是15.7%.(5)大黄效价的测定,以采用“6点”法为宜,即每次试验用小白鼠6组,3组给与标准品,另外3组给与试验品,所得的准确度与上述相仿。波希鼠李皮浸膏的效价测定,则用“4点”法或“6点”法均可。(6)所有试验一律采用粉状生药为实验室的比较标准,但是波希鼠李皮的效价太低,它的粉末不适於作为标准之用,可用波希鼠李皮乾浸膏来代替,作为比较标准。(7)本文对於效价测定及其计算方法都举例说明,并介绍了比较常法为简捷的相关效价计算法。(8)本法不但方便易行,而且有相当高的准确度;曾用在番泻、大黄、波希鼠李皮及其制剂,以及一些纯粹的蒽醌衍生物的效价测定,都获得了满意的结果。

A series of 8 new compounds with the dithia-dihydrostibiol structure has been compared for the therapeutic activities against schistosomiasis japonica in white mice. Each drug, thoroughly mixed with the finely powdered food, was fed to healthy mice for 14 days, and the LD_(10) and LD_(50) were evaluated. At the dosages of LD_(10) and LD_(50), each drug was fed to treat diseased mice (beginning on the 36th day after percutaneous infection on abdomen with 40 cercariae per mouse) for 14 days. After a holding period...

A series of 8 new compounds with the dithia-dihydrostibiol structure has been compared for the therapeutic activities against schistosomiasis japonica in white mice. Each drug, thoroughly mixed with the finely powdered food, was fed to healthy mice for 14 days, and the LD_(10) and LD_(50) were evaluated. At the dosages of LD_(10) and LD_(50), each drug was fed to treat diseased mice (beginning on the 36th day after percutaneous infection on abdomen with 40 cercariae per mouse) for 14 days. After a holding period of another 14 days mice were killed. Both portal system and liver were carefully scrutinized for worms. Basing on the average number of worms remained in each mouse, the therapeutic effects of out of the 8 compounds were better than that of tartar emetic administered orally.

用小白鼠试验8种二硫锑五环化合物,在同一毒性水平上比较对於日本血吸虫病的疗效。每种药物与饲料粉混匀喂饲健康小鼠14天,求出LD_(10)及LD_(50)。以这两个剂量,分别治疗病鼠(每鼠腹部皮肤感染40条尾蚴,5周後开始给药)14天,然後停药14天解剖,详细检查门静脉系统与肝内的余存虫。根据平均每鼠余存虫数,以吐酒石为标准,比较各药的疗效。结果发现Sb-1及Sb-19口服疗效较吐酒石为优。

Subjecting rats to a temperature of 78-90℃ for 5-6 minutes or a temperature of-2℃ for one hour depleted the ascorbic acid content of the adrenals. The depletion was significantly less in rats fed a diet containing 5% Panax ginseng powder for 3 weeks or in rats given a 50% aqueous extract of Ginseng (2.4 ml/animal) orally one hour before the stress. Normal rats subjected to high temperature stress appeared either unable to move or showed clonic convulsions. These rats did not regain their normal activity until...

Subjecting rats to a temperature of 78-90℃ for 5-6 minutes or a temperature of-2℃ for one hour depleted the ascorbic acid content of the adrenals. The depletion was significantly less in rats fed a diet containing 5% Panax ginseng powder for 3 weeks or in rats given a 50% aqueous extract of Ginseng (2.4 ml/animal) orally one hour before the stress. Normal rats subjected to high temperature stress appeared either unable to move or showed clonic convulsions. These rats did not regain their normal activity until 20-60 minutes after their removal from the oven. Most rats fed Ginseng appeared normal after staying 5-6 minutes in an oven at 78-90℃; none of these animals convulsed. The results indicate that the activity of the adrenal-pituitary system is inhibited by the administration of Panax ginseng. The mechanism involved may be that Ginseng interfered with the nervous control of the pituitary or that Ginseng has adrenocorticohormone-like action.

将白鼠置於78—90℃的烤箱5—6分钟或-2℃的冰箱一小时,可使动物肾上腺内的丙种维生素含量降低。以含5%人参粉末的饲料连续饲养三周,或於实验前一小时以50%人参水浸剂2.4毫升/鼠灌胃一次後,再使动物接受温度刺激,则肾上腺内丙种维生素含量的降低显著减少。经过高温刺激的动物,未服人参者或踡伏不动,或表现剧烈阵发性痉挛,经20—60分钟始渐恢复,而服用人参者,只个别动物有短时踡伏现象,无表现痉挛者。以上结果表明,服人参後脑下垂体——肾上腺的活动受到抑制,此作用可能由於人参抑制了垂体的神经管制,亦可能为人参有肾上腺皮质激素样作用。
