1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Immune modulating activity of ethanol extracts from Glycyrrhiza uralensis Fisch was investigated by conserving growth characteristics of several human cell lines. All of the samples did not show severe cytotoxicity on normal human liver cell line, WRL-68, showing less than 25% inhibition of cell growth. The crude extract and its fractionized samples (F1 and F3) inhibited the growth of human hepatoma, Hep3B, down to ca. 70% of normal cell growth in adding 1.0 g l(-1) of fraction F3. The result of anticancer experiments was well matched to the results of antimutagenicity using Chinese Hamster Lung cell lines(CHL V79). In adding 1.0 g l(-1) of fraction F1, the growth of human B cell was enhanced, up to 60% of control growth. The secretion of two kinds of cytokines, Interleukin-6 and Tumor Necrosis Factor-alpha from human B cells was also enhanced in adding the crude extract, but not the standards such as Glycyrrhizin (GL) or 18,beta-glycyrrhetinic acid (GM). It was found that both of the apoptosis and differentiation were more accelerated in supplementing the crude extract and fraction F1 than in adding the standards. A spot was found only in the crude extract and fractions, not standards by Thin Layer Chromatography(TLC) analysis. It tells that there must be another unknown component in crude and/or fraction F1 as a possible candidate of immune modulators. This component seems to be a derivative of a monomer, GM since its R(f) was close to the monomer. It was also interesting that glycyrrhizin, a major component in G. uralensis Fisch was biologically activated by first being hydrolyzed by an enzyme.
