The effect of carbon fiber after 6 month instillation on mouse

Project description:Gifu Prefecture and Gifu University are developing technologies for recycling used carbon fiber because the waste disposal process is highly cost and energy intensive. However, generation of carbon fiber dust during the recycling process is a serious issue, especially in the occupational environment. Recycling requires carbonization by partial firing treatment at 500℃ followed by firing treatment at 440℃: these processes produce dust as a by-product. In this study, three types of carbon fibers; before recycling, after carbonization, and after firing were evaluated for their toxic effects on mice. It is important to study the influence of carbon fibers on human health at a gene expression level.

Gene expression profiles in rat lung following intratracheal instillation with single-wall carbon nanotubes

Project description:Gene expression profiling of the rat lung following intratracheal instillation with single-wall carbon nanotubes (SWCNTs) was employed to gain insights into these molecular events. We attempted to characterize time-dependent changes in the gene expression until 754 days after intratracheal instillation with SWCNTs suspensions at 0.2 mg (L-SWCNT) and 0.4 mg (H-SWCNT) injected dose per rat, and to identify the shift from the acute-phase to the chronic-phase phase on the basis of evaluation at the molecular level.

Gene expression profiles in rat lung following intratracheal instillation with single-wall carbon nanotubes (SWCNTs)

Project description:Gene expression profiling of the rat lung following intratracheal instillation with SWCNTs was employed to gain insights into these molecular events. We attempted to characterize time-dependent changes in the gene expression until 754 days after intratracheal instillation with SWCNTs suspensions at 0.2 mg (L-SWCNT) and 0.4 mg (H-SWCNT) injected dose per rat, and to identify the shift from the acute-phase to the chronic-phase phase on the basis of evaluation at the molecular level. Groups of nine-week-old male Wistar rats (n= 6 per group/ time point) were intratracheally instilled with single-wall carbon nanotubes (SWCNTs) suspended in 0.4 ml distilled water including 0.1% Triton X-100 as a single injection 0.1 mg (L-SWCNT) and 0.4 mg (H-SWCNT) SWCNTs/ rat). Control groups received 0.1% Triton X-100 (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 M-BM-0C with a chow diet ad libitum, and dissected at 3 days, 7 days, 30 days, 90 days, 180 days, 365 days and 754 days post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Gene expression profiles in rat lung following intratracheal instillation with impurity-free single-wall carbon nanotubes

Project description:To further development of our gene expression approach to assess the effects of manufactured nanomaterials at the transcriptional level, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish characterization of physicochemical properties of impurity-free single-wall carbon nanotubes (SWCNTs). We have prepared two types of dispersed the SWCNTs, namely relatively small bundles and a short linear shape (CNT-1) and large bundles and a long linear shape (CNT-2), and attempted to characterize time-dependent changes in the gene expression of lung tissues until 90 days after intratracheal instillation with SWCNTs suspensions at 0.4 mg injected dose per rat. Groups of nine-week-old male Wistar rats (n= 4 per group/ time point) were intratracheally instilled with single-wall carbon nanotubes (SWCNTs) suspended in 0.4 ml of 1.0mg/mL bovine serum albumin (BSA) as a single injection 0.4 mg SWCNTs/ rat. Control groups received 1.0mg/mL BSA (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 M-BM-0C with a chow diet ad libitum, and dissected at 1day, 3 days, 7 days, 30 days, and 90 days post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Gene expression in the spleen; effect of maternal exposure to carbon black nanoparticle

Project description:The aim of this study was to investigate the effects of administration of carbon black nanoparticle (CB-NP) to pregnant mice on the development of lymphoid tissues in infantile mice. Pregnant ICR mice were treated with a suspension of CB-NP 95 microg/kg/time) by intranasal instillation, twice, on gestational day 5 and 9. Spleen and thymus were collected from offspring mice at 5 days post-partum.
