Apocynin reduced doxycycline-induced acute liver injury in ovariectomized mice.

To determine the physiological role of estrogen in the development of liver injury, we examined the sensitivities of sham and ovariectomy (ovx) mice against doxycycline (DOXY)-induced acute liver injury. Ovx or sham operation was performed in C57BL/6J wild-type female mice of eight weeks of age. Sham mice and ovx mice were treated with DOXY (240 mg/kg ip) 8 weeks after the operation, 30 min after apocynin (5 mg/kg) or saline administration.

Interleukin-6 modulates oxidative stress produced during the development of cisplatin nephrotoxicity.

Aims: We reported that interleukin-6 (IL-6) plays a protective role in the development of cisplatin-induced acute renal failure (ARF) through upregulation of anti-oxidative stress factors. In this study, we examined the effects of dimethylthiourea (DMTU), a hydroxyl radical scavenger, on the development of cisplatin-induced ARF in wild-type (WT) and IL-6(-/-) mice to determine how IL-6 contributes to modulation of oxidative stress caused by cisplatin.

Main Methods: WT and IL-6(-/-) male mice were given either cisplatin (30 mg/kg) or saline intraperitoneally.
