Objective: The aim of the present study was to evaluate the possible protective effect of Plantago major (P. major) extract against doxorubicin (DXR)-induced renal inflammation in rats. Materials and Methods: 80 male albino rats were randomly divided into 8 groups as follows: control, DXR, Ext (extract) 600, Ext1200, dexamethasone+DXR, vitamin E+DXR, Ext600+DXR, and Ext1200+DXR. Duration of the study was 35 days and DXR was intravenously injected on the 7th day of the experiment. Tumor necrosis factor-alpha (TNF-α) production and monocyte chemoattractant protein-1 (MCP-1) expression levels were assessed in the left kidney. Serum creatinine concentration and osmolarity were determined on the 1st, 14th, 21st, 28th and 35th days of the experiment. Results: DXR caused a significant increase in renal expression of MCP-1 and TNF-α production compared to control animals. Administration of dexamethasone, vitamin E and P. major extract significantly improved the expression of these inflammatory mediators compared to DXR group. Compared to day 1 in DXR group, serum osmolarity showed a significant increase on days 21, 28 and 35. Also, on these days, serum osmolarity in DXR group was significantly higher than that on the same days in control group. In Vit E+DXR and Ext 1200+DXR groups, there was no significant changes in serum osmolarity among different days of the study. However, in these groups, serum osmolarity on days 21, 28 and 35 showed a significant decrease compared to the same days in DXR group. Conclusion: Present results suggest that hydroethanolic extract of P. major protected renal tissue against DXR–induced renal inflammation.

Objective: Plantago major (P. major) is one of the medicinal crops in the world which has therapeutic properties for treatment of respiratory and gastrointestinal diseases. Theophylline is commonly used for the treatment of respiratory diseases. In this study, we investigated the protective effects of hydro-alcoholic extract of P. majoron lung in asthmatic male rats. Materials and Methods: 32 male adult rats were randomly divided into 4 groups: The control group (C) received normal saline; Asthma (A) group received a normal diet; Asthma group treated with Theophylline (200 mg/kg b.w.) (T); Asthma group which received p.major (100 mg/kg b.w.) (P). Asthma was induced by citric acid, 0.1 mg in form of spraying. The injection of P.major extract and theophylline was administered intraperitoneally for four weeks. At the end of the treatment, all of the rats were sacrificed and lungs were taken out, fixed, and stained with H&E, toluidine blue, and PAS, then histological studies were followed with light microscope. Results: Results showed that, in asthmatic group, the mean number of mast cells was significantly increased (p

Results: Results showed that, in asthmatic group, the mean number of mast cells was significantly increased (p<0.05). Thickness of alveolar epithelium and accumulation of glycoprotein in airways was increased. Moreover, in some of alveolar sac hemorrhaging was observed. Administration of p.major extract in asthmatic rats restored these changes towards normal group. Conclusion: The present study revealed that P. major compared with theophylline, has a protective effect on lung in asthmatic rats. [ABSTRACT FROM AUTHOR]

Objectives: The cause of a large category of acute renal failures is secondary as a result of using drugs. Cisplatin is one of the most effective anti-tumor drugs, but its use is limited due to renal toxicity. Plantago major is an annual plant belonging to the plantain family (Plantaginaceae). It has many therapeutic effects such as anti-inflammatory, analgesic, and antioxidant. It is used traditionally to treat demodicosis, infectious and respiratory diseases, and tumors. This study aimed to determine the effect of hydro-alcoholic extract of Plantago major on cisplatin-induced renal toxicity in rats. Materials and Methods: In this study, 60 male Wistar rats were equally divided into six groups including control group, cisplatin (7 mg/kg BW IP), vitamin E (100 mg/kg BW IP), and 70% hydro-alcoholic extract of Plantago major (300, 600, 1200 mg/kg BW PO) combined with cisplatin. For 21 days all rats in vitamin E and extract groups received vitamin E and extract of Plantago major, respectively. Cisplatin was injected on the sixth day. All rats were placed in metabolic cages and their 24-hour urine and blood samples were collected 1 and 5 days before and, 9, and 15 days after injection of cisplatin. Blood samples were collected, 6, and 12 days after cisplatin injection. To compare resulting biochemical parameters the mean results of 0 and 5 days (pre cisplatin injection days) were compared with 2 mean results of 8, 9 and 12 days. Mean concentration differences of serum urea, creatinine and potassium between days 0 and 5 and 8, 9, and 12 were determined. Results: Cisplatin lead to a significant increase in serum urea and creatinine levels and insignificant increase in serum potassium level compared with the control group. Serum urea, creatinine, and potassium levels were significantly reduced in rats which received vitamin E and the Plantago major extract in various doses. Conclusion: The results of our study show that vitamin E and Plantago major reduced the elevated serum levels of urea, creatinine and potassium probably due to antioxidant activity. Therefore, vitamin E and Plantago major have a protective role against cisplatin-induced renal toxicity. [ABSTRACT FROM AUTHOR]
