objective(s) there are some reports that the teratogenic effects of cyclophosphamide (cpa) can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. echinacea purpurea extract is antioxidative and immunomodulator drug. mesna (sodium 2-mercaptoethane sulfonate) is used for decreasing side effects of cpa, especially hemorrhagic cystitis. in this study, we...

In this study, the production of aflatoxin B1 (AFB1) and cyclopiazonic acid (CPA) was investigated in toxigenic and non-toxigenic Aspergillus flavus with respect to expression of aflR, veA and laeA genes that are involved to toxins production. A. flavus strains were cultured in YES broth at 28 °C for 4 days and the presence of (AFB1) and (CPA) was confirmed and measured by TLC and HPLC. The exp...

background: gallic acid (ga) is an endogenous plant phenol known to have antioxidant, free radical scavenging ability, anti‑inflammatory, anti‑cancer, and anti‑fungal properties. the aim of this study was to assess the protective effect of ga on cyclophosphamide (cpa)‑induced hepatotoxicity in male wistar rats. methods: sixty rats were grouped into six groups of 10 rats per group. group 1 recei...

Aspergillus oryzae strains are used extensively in the food industry. Some of these strains excrete alpha-cyclopiazonic acid (CPA), a mycotoxin which may provoke toxicoses in rats. Physicochemical methods may reveal the presence of this toxin, but they are inadequate to screen CPA-nonproducing (CPA-) strains. CPA production is revealed by either bacterial growth inhibition or alkalinization of ...

background: autophagy as a cellular pathway facilitates several immune responses against infection. it also eliminates invading pathogens through transferring content between the cytosol and the lysosomal vesicles and contributes to the cross-presentation of exogenous antigens to t lymphocytes via mhc class i pathway. autophagy induction is one of the main targets for new drugs and future vacci...

H1 receptor histaminergic antagonist, chlorpheniramine (CPA) participates in cognitive performance in various animal models. However, little is known regarding the effects of CPA microinjection into the amygdala on emotional behavior. The purpose of this study was to investigate whether CPA microinjection into the amygdala has the same effect on two models, one anxiety- and the other fear-media...

The purpose of this study was to characterize the concentration-response effects of cyclophosphamide (CPA) with and without dexamethasone (DEX; 10 microM) on the expression of CYP3A4 and CYP2B6 in cultured human hepatocytes at concentrations representative of standard- and high-dose CPA therapy (25 to 750 microM). CPA produced concentration-dependent increases in CYP3A4 and CYP2B6 activity and ...
