Effects of ginsenosides on carbachol-stimulated formation of inositol phosphates in rat cortical cell cultures.
Article in Neurochemical research, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
We examined the effect of ginseng total saponins (GTS) on phosphoinositide metabolism stimulated by activation of muscarinic receptor using rat cortical cultures. Carbachol stimulated formation of [3H]inositol phosphates ([3H]InsPs) by 3.3-fold over basal level in [3H]inositol-prelabeled cells. Pretreatment of GTS inhibited formation of [3H]InsPs evoked by carbachol by 70%-90%. Addition of GTS alone had no effect on the basal formation of [3H]InsPs. The inhibitory effect of the GTS on carbachol-stimulated formation of [3H]InsPs was dose- and time-dependent. IC50 was 6.0 +/- 2.8 microg/ml. We also examined the effect of GTS on [3H]InsP1, [3H]InsP2, or [3H]InsP3 formation evoked by carbachol. Although GTS had no effect on the basal [3H]InsP1, [3H]InsP2, or [3H]InsP3 formation, pretreatment of GTS inhibited [3H]InsP1, [3H]InsP2, or [3H]InsP3 formation evoked by carbachol, respectively. Addition of individual ginsenosides such as ginsenoside Rb1, Rc, Rd, Re, or Rg2 had no effect on the basal formation of [3H]InsPs, whereas pretreatment of ginsenoside Rb2, Rc, Rd, Re, Rf, Rg1 or Rg2 inhibited formation of [3H]InsPs evoked by carbachol by 79%-89%. The results suggest that the inhibitory effect of GTS and its individual ginsenosides on carbachol-stimulated formation of [3H]InsPs in cortical neurons could be one pharmacological action of Panax ginseng.
