Abstract:
This article was aimed to study anti-inflammatory effects of petroleum ether extract from Citrullus lanatus vine (PEECLV) and explore the mechanism. The methods of ear swelling with xylene, increasing of peritoneal capil-lary permeability, and paw edema with egg albumin were used in the establishment of mice models, respectively. Granuloma with cotton pellet, and paw edema with carrageenan were used in the establishment of rat models, re-spectively. Observation was made on anti-inflammatory effects of PEECLV. The content of nitrous oxide (NO) and nitric oxide synthase (NOS), as well as the level of TNF-α and IL-1β in blood serum were measured among granu-loma with cotton pellet rat models. Contents of malondialdehyde (MDA), prostaglandin E2 (PGE2), 5-HT, histamine (His), and protein in inflammatory exudates from the paw edema with carrageenan rat model, as well as contents of NO and NOS in blood serum, and activity of superoxide dismutase (SOD) were measured in order to study the possi-ble anti-inflammatory effects. The results showed that PEECLV can suppress the ear swelling with xylene, the in-creasing of peritoneal capillary permeability, and the paw edema with egg albumin in mice, as well as granuloma with cotton pellet, paw edema with carrageenan in rats. It had anti-inflammatory effects at different degrees. The content of NO and NOS, as well as the level of TNF-α and IL-1β in blood serum were reduced in granuloma with cotton pellet rat models. The content of MDA, PGE2, 5-HT, His, and protein content were reduced in inflammatory exudates from the paw edema with carrageenan rat model. The increasing of NO and NOS in blood serum was inhib-ited. And the activity of SOD was increased. It was concluded that PEECLV had certain anti-inflammatory effects. Its mechanism may be related to the influence of the production of inflammatory mediators and antioxidant.
