The blood concentrations of cephazolin were determined in 8 hemodialysis patients during dialysis or in the interval,following administration of drug via catheterized tube for dialysis or VI route. According single compartment model,the t1/2 of drug was calculated by two-points method, The results showed that t1/2 were 6.76±1. 62h,48.1±21.5h,respectively.

In addition, the two main technique problems, two-points NUC algorithm implemented by hardware and ensurement of image frame integrality, are discussed .

When he designs the grandiose blueprint of chinese socialist construction and guides the practice of chinese revolution and construction, DENG Xiao ping insists on the "Theory of Two-points" as the basic principle of methodology all the time.

The obtained results are applied to a one-sided two-points tangential interpolation for matrix functions.

Starting with the determination of the two-points function in the Landau gauge given by Wightman and Strocchi, we build a more economic realization of this gauge, following the basic principles they have proposed.

Solar wind measurements on board several spacecraft were used to study the two-points correlations of the solar wind plasma structures.

We use this result to discuss some applications concerning the two-points blow-up of CP2.

Such plans are called 'valid' if they obey the classical two-points condition on the operating characteristics.

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates (I) and (II) are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion. In the absence of electromagnetic phenomena the theory reduces practically to Einstein's theory.

In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile is suitable for two...

In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile is suitable for two points pick, which gives great facilities to handling and transpotation. Besides, 18% of steel saving can still be made. This paper only presents the principle and calculations. The testing results will be given later.

Three hundred and eleven herb drugs (most of which are used in chinese medicine) and 47 composite recipes were screened for antitumor activity in animals. The drugs or recipes were selected from those commonly used in Chinese medicine in the treatment of neoplasms or tumorous diseases or from drugs that belong to the same genus or the same species as certain known antitumor herbs. The preparations employed included decoctions, tinctures, extracts, electrophoretic fractions and such constituents as alkaloids,...

Three hundred and eleven herb drugs (most of which are used in chinese medicine) and 47 composite recipes were screened for antitumor activity in animals. The drugs or recipes were selected from those commonly used in Chinese medicine in the treatment of neoplasms or tumorous diseases or from drugs that belong to the same genus or the same species as certain known antitumor herbs. The preparations employed included decoctions, tinctures, extracts, electrophoretic fractions and such constituents as alkaloids, essential oils, glycosides etc. Ehrlich carcinoma (both the ascitic and the solid from) and sarcoma 180 were routinely employed for the screening; whereas other mouse tumors including spindle-cell sarcoma, sarcoma AK, reticulo-cell sarcoma L_2, sarcoma B_(22) and spon- taneous carcinoma of the breast, as well as rat tumors, Yoshida ascites sarcoma and Walker carcinoma 256 were also used in some of the tests. The drugs were given once daily and, with a few exceptions, for 6—14 days. Essential oils and soluble crystalline substances were given intraperitoneally or subcutaneously while the rest were administered through stomach tube. Inhibition of tumor growth by 30% or more in the case of solid tumors or prolongation of survival by 3 days or more in the case of ascites tumors were taken as the criteria for antitumor activity. Of the 358 preparations screened 3 (0.8%) showed definite antitumor effects, namely the essential oil of Atractylodes macrocephala Koid (白术), the tincture of Bombyx batryticatus (殭蚕) and Ye Ke San (a composite recipe meaning "powder for dysphagia"), 350 were ineffective and the results of the remaining 5 were inconclusive. Contrary to our experimental data clinical observations on neoplastic patients have claimed encouraging results for many of the composite recipes tested in the present investigation. As the assessment of antitumor therapy requires large scale and prolonged observations, further clinical and experimental investigations are necessary before definite opinions on the effectiveness of these recipes are to be expressed. The question arises as to the cause of the low incidence of positive screening results. To the authors, two points seem to be worthy of consideration. Firstly, in the crude preparations, like decoctions and extracts, effective antitumor contituents, if present, most likely exist in very low concentrations, and sometimes may even be lost or inactivated during processing. Secondly, the nature, actions and potency of the crude preparations are subjected to the influences of a number of variables. These include differences or irregularities in species, district of cultivation, time of harvesting and conditions of preservation and preparation. The non-uniformity of even one of these variables may introduce significant differences in the quality of the final preparation and this in turn would lead to variability of the screening results and difficulty in assessing the antitumor effects. It would be preferable to extract the crystalline constituents of the herb drugs for antitumor screening experiments or as an alterative to make refined preparations from which certain "inactive" constituents like tannins, sugars, gums etc. are removed so as to render concentration of the effective constituents possible.
