Objective: To investigate the protective effects and possible mechanisms of ferulic acid on diabetic nephropathy by observing the effects of ferulic acid on the level of inflammation and autophagy in glomerular mesangial cells induced by high glucose.

Methods: SV40 MES 13 cells were cultured and randomly divided into the following groups: normal group (Control, 5.6 mmol/L glucose), mannitol group (Man, 30 mmol/L mannitol), high glucose group (HG, 30 mmol/L glucose), ferulic acid group (FA, 30 mmol/L glucose + 12.

Diabetic nephropathy (DN) is one of the most serious microvascular complications following diabetes mellitus (DM). Ferulic acid (FA), a phenolic acid widely found in plants, has multiple pharmacological effects such as anti-oxidation, anti-inflammation and anti-tumor. However, the current research on FA in the field of DN is insufficient.

Article Synopsis
  • - The study examined how different doses of ketoconazole (KCZ) impact liver and testis functions in Kunming mice, dividing them into four groups: a normal group and three KCZ treatment groups with varying doses (30 mg/kg, 50 mg/kg, 70 mg/kg).
  • - After 3 weeks of treatment, results showed that KCZ significantly increased liver enzyme levels (AST and ALT) and decreased testicular enzyme activities (γ-GT, ACP, LDH) compared to the normal group, indicating physiological damage.
  • - Histological analysis revealed pathological changes, including denatured liver cells and reduced spermatogenic cells in the testis, with greater damage observed at higher doses of KCZ,

Diabetic nephropathy (DN) is one of the complex and severe complications of diabetes mellitus (DM). Icariin (ICA) is a flavonoid extracted from the leaves and stems of Herba epimedii with a wide range of pharmacological effects, such as anti-osteoporosis, anti-fibrosis, anti-aging, anti-inflammation and antioxidation. The purpose of our study was to explore the renal protective effect of ICA on DN in mice and its possible mechanisms.

Testicular damage is the anomaly that will often accompany diabetes mellitus. Thus, this study aimed to investigate the role that total flavonoids of Epimedium (TFE) played against streptozotocin (STZ)-induced diabetic testicular dysfunction and to elucidate the mechanism of action. The diabetic rat model was induced by vein injection of STZ in healthy rats.

Objective: To study the effect of ursolic acid on cardiomyopathy in mice with diabetes induced by high-fat diet combined with low dose streptozotocin, and to explore its possible mechanism.

Methods: Thirty male ICR mice were randomly divided into control group (=10) and moulding group (=20), the mice in the two groups were fed with regular diet and high-fat diet respectively for 6 weeks, and then the mice in the moulding group were injected with streptozotocin (30 mg/kg) for 5 successive days to induce diabetes mellitus (DM). Fasting blood glucose (FBG) was measured after 9 days.

Objective: To investigate whether total triterpene acids (TTAs), isolated from Cornus Fructus, attenuates renal function by reducing oxidative stress and down-regulating the expression of transforming growth factor β1 (TGF-β1).

Methods: Diabetes was induced by an injection of streptozotocin (40 mg/kg intravenously). Thirty rats were randomly divided into three groups: control group, diabetic model group and TTAs treatment group (50 mg/kg, intragastrically) administrated for 8 weeks from 5th to 12th week.

In order to search for novel potential agents for the treatment of chronic kidney diseases (CKD), nitric oxide (NO)-releasing derivatives (5a-c) of ferulic acid were synthesized and characterized by MS, 1H NMR, and elementary analysis. They showed different NO-releasing rate in the absence or presence of L-cysteine in vitro. In the adenine induced CKD rats, these compounds revealed reno-protective effect via lowering blood urea nitrogen (BUN), creatinine (Cr) in serum and malondialdehyde (MDA) in kidney, increasing NO and superoxide dismutase (SOD) level in kidney.
