Objective: Vasculitis is the basic pathological change of systemic lupus erythematosus (SLE). Radix Paeoniae Rubra (RPR), a traditional Chinese herb with the function of reducing blood stasis, has anti-inflammatory and immunoregulatory properties. This study explored the effects of RPR on the kidneys of lupus-like symptoms of mrl (MRL/lpr) mice from the perspective of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and platelet endothelial cell adhesion molecule-1 (PECAM-1). Methods: Eighteen MRL/lpr lupus model mice were randomly divided into three groups, the model control group, prednisone-treated group, and RPR-treated group, and 6 C57BL/ 6 mice were classified as a control group. After the mice had been treated for 12 weeks, the expression of ICAM-1, VCAM-1 and PECAM-1in the kidney was determined by immunohistochemistry and Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Results: After 12 weeks, there were significant differences in body weight in the model, prednisone and RPR groups compared with the normal group (P <0.05). Pathological observation: Compared with the model group, the proliferation of inflammatory cells infiltrated glomeruli and interstitial cells in prednisone and RPR groups were reduced, and renal pathological damage was reduced. Compared with the model group, urine protein level of prednisone and RPR groups were reduced with no significance (P> 0.05). The mRNA expression levels of ICAM-1 and VCAM-1 were significantly reduced in the prednisone group and RPR group compared with the model group (P <0.05 or P <0.01). Meanwhile, the immunohistochemistry expressions of ICAM-1 and VCAM- 1 expressed in the kidney were significantly reduced in the prednisone group and RPR group (P <0.01 or P <0.05). However, The mRNA expression level and the immunohistochemistry expressions of PECAM-1 expressed in the kidney were reduced in each treatment group (prednisone group and RPR group), but these differences were not significant (P>0.05). Conclusions: ICAM-1, VCAM-1 and PECAM-1 expression in the model group was found to be significantly increased. In addition, RPR could reduce the expression of ICAM-1, VCAM-1 and PECAM-1 in MRL/lpr lupus mice as effectively as prednisone, which may result in the dosage reduction of prednisone, thus decreasing the toxicity and improving the efficacy of prednisone - based treatment of SLE.

Synbiotic cheese made of goat milk, bacterial starter Lactobacillus rhamnosus, and porang glucomannan has been reported to have anti-inflammatory effects. This study aimed to determine the effect of synbiotic cheese on gene expression and protein levels of intercellular cell adhesion molecule-1 in a rat model of gastric injury. Male Wistar rats were divided into six groups. For 28 days, three groups received an increasing dosage of synbiotic cheese and one group received one dosage of probiotic cheese. For comparison, there was a placebo group receiving nothing and another group receiving indomethacin alone. On day 29, all rats received 20 mg/kg indomethacin intragastrically to induce gastric injury. Twenty-four hours later, rats were euthanized, and gastric tissue was taken for the quantification of intercellular cell adhesion molecule-1 gene and protein expressions. The results showed that pretreatment of synbiotic cheese caused significant suppression of intercellular cell adhesion molecule-1 expression. Synbiotic cheese at a dose of 0.36 g/day significantly suppressed intercellular cell adhesion molecule-1 protein expression (P < 0.05), whereas synbiotic cheese at a dose of 0.72 g/day significantly suppressed both gene expression and protein levels of intercellular cell adhesion molecule-1 (P < 0.05) compared to the indomethacin alone group. We conclude that synbiotic cheese may protect from gastric injury through modulation of intercellular cell adhesion molecule-1.
