Sepsis is an acute condition caused by the systemic inflammatory response syndrome to an infection. There are very few drugs that could improve the severe conditions in patients with sepsis. Hence, it is important to consider different treatment options. In this survey, we studied the effect of adenosine N1-oxide (ANO) and pioglitazone on rats with cecal ligation and perforation (CLP). They were randomly divided to four groups (n = 10) including Group A: as control group receiving normal saline, Group B: the rats with CLP as surgical control group, Group C: the rats receiving ANO, and Group D: the rats receiving pioglitazone. Interleukin (IL) -6, IL-1β, tumor necrosis factor alpha (TNF-α), nitric-oxide (NO) in serum blood and superoxide dismutase (SOD), catalase (CAT) malondialdehyde, (MDA) and myeloperoxidase (MPO) in liver and spleen homogenates were measured. The amount of antioxidant enzymes in the spleen and liver, and finally cell viability and rats’ survival were investigated. The measurement of blood serum nitric-oxide and survival of all groups of rats were also performed. The results indicated that both drugs could cause a decrease in IL-1β, IL-6, TNF-α and NO in rat blood serum and MDA and MPO in the liver and spleen homogenates, however, a significant increase in SOD and CAT in the liver and spleen homogenates in rats that received ANO and pioglitazone was observed compared to rats with CLP group. Cell viability and rats’ survival were significantly improved in rats that received ANO and pioglitazone compared to rats with CLP group. Adenosine N1-oxide showed stronger and more effective effects.

Autoimmune diabetes is one of the most common metabolic diseases with increasing prevalence in the past decades in which pancreatic Langerhans β cells are destroyed and lead to lack of insulin due to increased blood sugar. One of the consequences of diabetes is glomerular disease of the kidney, also called diabetes nephropathy. Different studies have been carried out on the effects of triterpenoids and their medicinal effects on diabetes mellitus. betulinic acid, a pentacyclic triterpenoid of Terpenes, is found in bushes and trees. Its medical effects are also approved by many studies. In this survey, we studied the effect of betulinic acid on diabetic inbred C57BL/6 male mice. They were randomly divided to three groups. Group A: Consisted of healthy mice which received citrate buffer. Group B: Diabetic mice without any treatment and group C: Treated diabetic mice with betulinic acid. The level of blood insulin level, fasting blood glucose, C-peptide, TNF-α, IFN-γ, and IL-1 cytokines were measured and pathologic studies of the kidney were performed. The results showed that betulinic acid could increase insulin and C-peptide, and decrease fasting blood sugar, kidney lesions and TNF-α, IFN-γ, IL-1 in the treated groups. The differences were significant except for IL-1. Betulinic acid through reduction of inflammatory cytokines could have positive effects on inflammatory and autoimmune disease including autoimmune diabetes.
