Cover for Zearalenone: an estrogenic mycotoxin with immunotoxic effects.

This chapter presents a study aiming to verify if zearalenone (ZEA), like oestrogen, can induce alterations in some immune parameters in female ovariectomized Wistar rats. Results revealed that female rats treated with ZEA for 28 days showed a decreased food intake and a significantly lower body...

Cover for Immunotoxic and toxic evaluation of subchronic exposure to saxitoxin in rats.

Forty male rats were equally divided into 4 groups and administered with saxitoxin (STX) at 0, 10, 30 and 90 µg/kg body weight by gavage for 28 days. Bone marrow, lymphocyte proliferation and histopathology of selected tissues were analysed after euthanasia. It was shown that body weight gain, food ...

Cover for Production of a saxitoxin standard from cyanobacteria.

A methodology for the production of a saxitoxin (STX) standard from cyanobacteria (Raphydiopsis brookii strain SPC 338) was developed. The cyanobacterium was cultured in 5-litre culture bottles in ASM-1 medium, pH 7.4 at 22±1°C, under continuous light at an irradiance of 45-50 mmol m-2 s-1 and...

Cover for Comparative study of monocrotaline toxicity on peritoneal macrophage activity when dosed for 14 or 28 days.

This study evaluated if monocrotaline (MCT) administration to rats for 28 days has a modulatory effect on nitric oxide (NO) production by peritoneal macrophages (MO). MCT from Crotalaria spectabilis was dissolved and mixed with 1.0% phosphoric acid solution. Distilled water was then added to...
