Table 3 Group size, body weight and hepatosomatic index for male and female offspring

From: Long-term effects of environmentally relevant doses of 2,2',4,4',5,5' hexachlorobiphenyl (PCB153) on neurobehavioural development, health and spontaneous behaviour in maternally exposed mice

Gender Group N BW PND21 BW Week16 HSI Week16

  1. The animals were exposed to PCB153 throughout gestation and lactation, via maternal consumption of spiked feeds based on fish or casein. High dose feeds (Fish High PCB and Casein High PCB) contained ~1500 μgPCB153/kg feed. Data are presented as mean ± SEM of offspring that survived to week16.
  2. HSI = Hepatosomatic index, BW = body weight, PND = Postnatal day. Groups with different superscript letters are significantly different, within the same gender (Mann-Whitney U, p < 0.01).
