Preparation of Self-microemulsion Solids of Kaempferia galanga (L.) Volatile Oil and Its Effect on Rats with Gastric Ulcer.
Article in AAPS PharmSciTech, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
Kaempferia galanga volatile oil (KVO), the main effective component of the medicinal plant Kaempferia galanga L., possesses a variety of pharmacological activities such as anti-inflammatory, antioxidant, and anti-angiogenic activities and has therapeutic potential for gastric ulcer (GU). However, poor solubility as well as instability limits the clinical application of KVO. In this study, K. galanga volatile oil self-microemulsion solids (KVO-SSMEDDS) were prepared to improve its bioavailability and stability, and the therapeutic effects were evaluated in a rat model with GU. The ratio of oil phase, emulsifier, and co-emulsifier in the KVO-SMEDDS prescription were optimized by plotting the pseudo-ternary phase diagram with the star point design-response surface method. Based on the optimal prescription, self-microemulsifying drug delivery system (SMEDDS) was prepared as solid particles (S-SMEDDS). The prepared KVO-SSMEDDS had a rounded and non-adhesive appearance, formed an O/W emulsion after dissolution in water, and had a uniform particle size distribution with good stability and solubility. It was administered to GU model animals, and the results showed that a certain dose of KVO-SSMEDDS solution could increase the content of gastric mucosal protective factors PGE2, TGF-α, and EGF in gastric tissues and serum, and the expression of inflammatory factors IL-8 and TNF-α was downregulated. Meanwhile, the expression of the NF-κB/COX-2 pathway proteins was inhibited. In conclusion, the prepared KVO-SSMEDDS has good dispersion, solubility, and stability and has a therapeutic effect on rats with GU.
