INTRODUCTION Tendon injuries are notorious for slow and functionally inferior healing. It is claimed that cell-based therapy would result in faster and more efficient healing of injured tissues with less postoperative complications. Given the limitations associated with ex vivo cellular expansion, we tried to evaluate the possible effects of intratendinous(More)
Generation of reactive oxygen species (ROS) leads to serious tissue injuries. The effect of cyclopiazonic acid (CPA) on oxidative stress markers in the liver and kidneys of broiler chicks was studied. Ten-day-old male broiler chicks (Ross 308) were assigned into the control and test groups, which received normal saline and 10, 25, and 50 μg/kg CPA,(More)
This study aimed to investigate the protective and regulatory effects of silymarin (SMN) and melatonin (MEL) on streptozotocin (STZ)-induced diabetic changes in cytochrome P450 3A2 (CYP 3A2) and glutathione peroxidase (GPX) expression and antioxidant status in the liver. Male Wistar rats were divided into five groups, including: control (C), untreated(More)
Cerebral coenurosis is the intermediary larval stage of Taenia multiceps, which affects intermediate hosts, particularly sheep and goats. In this report, gross and microscopic features of three scarce natural coenurosis cases, a one-year-old ram and two lambs of 7 month old from a flock are explained. At necropsy, numerous small cysts measuring 5 to 10 mm(More)
Adipose tissue is a good source for isolation of cells with stem-cell-like properties. The effects of undifferentiated cultured bone marrow stromal cells (BMSCs) and omental adipose-derived nucleated cells (OADNCs) on peripheral nerve regeneration were compared in a rat nerve regeneration model. A 10-mm sciatic nerve defect was bridged using a vein graft.(More)
The aim of this study was designed to evaluate the possible protective effects of Nigella sativa (NS) on the neuronal injury in the sciatic nerve of rats. The rats were randomly allotted into one of the three experimental groups: A (control), B (only trauma) and C (trauma and treated with NS); each group contain 10 animals. Sciatic nerve injury was(More)
Reconstruction of vascularity is an early event in fracture healing and upregulation of angiogenesis may therefore promote the formation of bone. We have investigated the potentiality of autogenous free nonvascularized greater omentum to stimulate the formation of bone in an experimental hypertrophic nonunion model. Twelve dogs assigned into two identical(More)
BACKGROUND Spinal motoneuron neuroprotection by vitamin B12 was previously reported; the present study was carried out to evaluate neuroprotectivity in the dorsal root ganglion sensory neuron. METHODS In present study thirty-six Wister-Albino rats (aged 8-9 weeks and weighing 200-250 g) were tested. The animals were randomly divided into 6 groups which(More)
In recent years, cell transplantation has become a focus of attention and reliable outcomes have been achieved in regeneration of the sciatic nerve. The effect of undifferentiated bone marrow stromal cells (BMSCs) on peripheral nerve regeneration was studied using a rat sciatic nerve regeneration model. A 10-mm sciatic nerve defect was bridged using an(More)
BACKGROUND Diabetes in humans induces chronic complications such as cardiovascular damage, cataracts and retinopathy, nephropathy and polyneuropathy. The most common animal model of human diabetes is streptozotocin (STZ)-induced diabetes in the rat. The present study investigated the effects of Nigella sativa hydroalcholic extract on glucose concentrations(More)
