Postnatal development and fertility of offspring from mice exposed to triphenyltin (fentin) hydroxide during pregnancy and lactation.

Fentin or triphenylthin (TPT) is an organotin compound (OTC) widely used as an agricultural fungicide and miticide. It is well known that TPT exerts adverse effects on the reproductive and immune systems and may disrupt the endocrine system, raising concerns regarding the risks posed by exposure to this metal on environmental and human health. In this study the effects of maternal exposure to TPT at doses of control (0), 1.

Prophylactic effects of short-term acupuncture on Zusanli (ST36) in Wistar rats with lipopolysaccharide-induced acute lung injury.

Objective: To evaluate the prophylactic effects of short-term manual acupuncture stimulation on Zusanli (ST36) on acute lung injury (ALI) caused by lipopolysaccharide instillation in Wistar rats.

Methods: Thirty-two Wistar rats were randomized into 4 groups (n=8) classified by the absence or presence of lipopolysaccharide instillation [negative (NC) and positive control (PC), respectively], and performance of sham or real needle stimulation [sham (SA) or real (RA) acupuncture, respectively]. Manual acupuncture was performed daily for 5 minutes over four consecutive days (days 1 to 4).
