The routine diagnosis of Neospora caninum abortion is based upon histopathologic changes in fetal tissues and identification of tissue parasites by immunohistochemistry. Confirmation of N. caninum infection by immunohistochemistry has low sensitivity. In the present study, we examined the utility of PCR in detecting N. caninum infection in fetal tissues from spontaneous bovine abortion. DNA was...

The expression of the c-myc gene product in renal cell carcinomas was examined by immunostaining with monoclonal antibody (m,\h) MYC-1. The effects of preservation and fixation of tissues on staining were first examined. In cryostat sections fixed with 4% buffered formalin for 15 min, staining was observed in the nucleus. On the other hand, in paraffin sections after fixation with 10% formalin,...

background: studies have emphasized the effect of trigonella foenum-graecum extract on the reduction of pain and inflammation. objective: in this research we investigated the mechanisms of trigonella foenum-graecum extract in reducing pain and inflammation induced by formalin. methods: male albino mice (weight 20 - 25 g) were evaluated through the injection of 2 microliters of formalin to the p...

This study investigated the role of g-aminobutyric acid (GABA) and GABAA receptors in the spinal cord in the expression of pain behaviors evoked by injection of formalin in concentrations ranging from 0.25 to 2.5% in the hindpaw of the rat. Two approaches were used. The first approach compared the effect of drug treatment to saline at each concentration of formalin. The second approach examined...

objective(s): there are many reports about the role of rostral ventromedial medulla (rvm) in modulating stress-induced analgesia (sia). in the previous study we demonstrated that temporal inactivation of rvm by lidocaine potentiated stress-induced analgesia. in this study, we investigated the effect of permanent lesion of the rvm on sia by using formalin test as a model of acute inflammatory pa...

Disinfection tests were conducted on eggs from rainbow trout Oncorhynchus mykiss, cutthroat trout O. clarkii, and brown trout Salmo trutta to evaluate hydrogen peroxide (H2O2) as an egg disinfectant. A daily drip of 500 mg/L hydrogen peroxide for 35 min on eyed brown trout eggs safely led to significantly reduced bacterial abundance relative to untreated controls, but abundance did not differ s...
