Fig. 8From: Exploration of the mechanisms underlying the beneficial effect of Luo Tong formula on retinal function in diabetic rats via the “gut microbiota–inflammation–retina” axisEffect of LTF and CaD on gut microbiota in a rat model. A The α diversity of the gut microbiota. B Bray–Curtis distance PCoA. C The levels of Firmicutes and Bacteroidetes, and the ratio between the two bacteria. D Heatmap represents the hierarchical clustering based on the microbial composition at the genus level. Data are expressed as mean ± SD (n = 6) (*p < 0.05: vs. normal control group; △p < 0.05: vs. diabetic control group)Back to article page
