BACKGROUND/AIMS Acute pancreatitis (AP) is an inflammatory disease characterized by acinar cell damage and inflammation of the pancreas with infiltration of leukocytes, predominantly neutrophils. We investigated whether neutrophil depletion protects against experimental AP induced by L-arginine. METHODS AP was induced in C57BL/6 mice via two intraperitoneal L-arginine (4 g/kg) injections. Mic...

Calcitriol, a metabolite of vitamin D, is often used in osteoporosis clinics. However, the material has other bioactivities; for example, it accelerates angiogenesis, has anti-inflammatory properties, and inhibits oxidative stress. We investigated the effects of calcitriol in a random skin flap rat model. "McFarlane flap" models were established in 84 male Sprague Dawley rats, divided into two ...

Gastro-oesophageal reflux is frequent in chronic airway diseases and is considered a trigger for symptoms. In animal models, bilateral vagotomy or muscarinic antagonists prevent the increase in airway resistance and the microvascular leakage induced by acute oesophageal acid instillation. The present study investigates lung inflammation and remodelling in an animal model of chronic gastro-oesop...

BACKGROUND Rodent mesenchymal stem/stromal cells (MSCs) enhance repair after ventilator-induced lung injury (VILI). We wished to determine the therapeutic potential of human MSCs (hMSCs) in repairing the rodent lung. METHODS In series 1, anesthetized rats underwent VILI (series 1A, n = 8 to 9 per group) or protective ventilation (series 1B, n = 4 per group). After VILI, they were randomized t...

A rat model of sarcomatoid mesothelioma, mimicking some of the worst clinical conditions encountered, was established to evaluate the therapeutic potential of intracavitary curcumin administration. The M5-T1 cell line, selected from a collection established from F344 rats induced with asbestos, produces tumors within three weeks, with extended metastasis in normal tissues, after intraperitoneal...

Inflammatory bowel diseases, such as ulcerative colitis, cause significant morbidity and decreased quality of life. The currently available treatments are not effective in all patients, can be expensive and have potential to cause severe side effects. This prompts the need for new treatment modalities. Enoxaparin, a widely used antithrombotic agent, is reported to possess anti-inflammatory prop...

OBJECTIVE Crocin, as an active constituent of saffron, has many biological functions including antioxidant and anti-inflammatory activities. The present study was aimed to investigate the effects of crocin and chlorpheniramine on local edema induced by histamine. MATERIALS AND METHODS Local edema was induced by subcutaneous injection of histamine (100 μl, 0.1%) in ventral surface of right hin...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

Paeonol is an active component of Moutan Cortex Radicis and is widely used as an analgesic, antipyretic, and anti-inflammatory agent in traditional Chinese medicine. We wanted to determine the role of paeonol in treating adult respiratory distress syndrome (ARDS). We established an acute lung injury (ALI) model in Sprague-Dawley rats, which was similar to ARDS in humans, using intratracheal adm...
