Apolipoprotein E (apoE), a lipid transporting protein, has been postulated to participate in nerve regeneration. To better clarify apoE function in the olfactory system, we evaluated the amount and distribution of apoE in the olfactory bulb following olfactory nerve lesion in mice. Olfactory nerve was lesioned in 2- to 4-month-old mice by intranasal(More)
The apolipoprotein E4 (apoE4) genotype is a major risk factor for Alzheimer's disease (AD); however, the mechanism is unknown. We previously demonstrated that apoE isoforms differentially modulated neurite outgrowth in embryonic neurons and in neuronal cell lines. ApoE3 increased neurite outgrowth whereas apoE4 decreased outgrowth, suggesting that apoE4 may(More)
Hepatic hemopoiesis is apparent in the chicken embryo on day 7 of incubation (Hamburger and Hamilton Stage 30), and a peak in hemopoietic activity occurs on day 14 (Stage 40). During this period, the differentiation of hemopoietic cells was examined by light microscopy and by transmission and scanning electron microscopy. Glycol methacrylate sections were(More)
The effects of dietary protein on the metabolism of butylated hydroxytoluene (BHT) were examined in the present study by comparison of the pharmacokinetics of BHT in rats fed different levels of dietary protein. Groups of young female rats were fed diets containing 24%, 8%, or 4% protein, as supplied from casein, for 4 weeks. At the end of the feeding(More)
Hemopoiesis in the liver of the chicken embryo begins on day 7 of incubation (Hamburger and Hamilton Stage 30) and peaks on day 14 (Stage 40). During this time frame, the differentiation of hepatic cells was examined by light microscopy, transmission and scanning electron microscopy, and morphometry. The avian liver is a closely packed mass of dendriform(More)
Individual and combined effects of dietary protein and butylated hydroxytoluene (BHT) were investigated. Groups of young, female rats were fed diets containing 24, 8, or 4% protein for 5 weeks. During the fifth week, BHT was administered intragastrically to half the rats in each group at 250 mg/kg/day for 7 days. Reduction of protein intake, particularly to(More)
