The trigemino-cerebellar projections of the rats were studied by introducing HRP microelectrophoretically in to various deep icerebellar nuclei (dentate nucleus, ND; interpositus nucleus, anterior part, NIA; interpositus nucleus, posterior part, NIP; fastigial nucleus, NF). The results indicate that all nuclei of the trigeminal nerve give their projections to bilateral (mostly ipsilateral) deep cerebellar nuclei. Most of them come from the interpolar and oral subnuclei of the spinal nucleus of the trigeminal nerve. The caudal subnucleus of the spinal nucleus of the trigeminal nerve and the principal sensory nucleus of the trigeminal nerve (VP) take the second place. Least of all come from the mesencephalic nucleus (ME) and the motor nucleus (MO) of the trigeminal nerve. In addition, cells in the region ventrolateral to the motor nucleus (VMO) and in the root of the trigeminal nerve (VR) also project to deep cerebellar nuclei. Fibers coming from ME terminate mostly in NF and NIA. Fibers from the spinal nucleus of the trigeminal nerve and VP terminate more in NIP and ND. Fibers from MO terminate in NF, NIA and ND. Fibers from VMO and VR have the same termination as those from the sensory nuclear complex of the trigeminal nerve.

To study the function of lipoprotein lipase (LPL)with Asn291 Ser and Lys312insC compound mutation in LPL gene knockout heterozygous (LPL~(+/-)) mice. The results showed that triglycerides, free fatty acids, blood glucose and weight of LPL~(+/-) mice were higher than those of c57 mice(P<0. 05). The expressions of LPL Mrna and LPL protein of LPL~(+/-) group were lower than those of c57 group(P<0.05). The injection of Asn291Ser +Lys312insC protein caused little change of the lipid mass and LPL activity,but the injection of normal LPL protein induced obvious decrease of lipid mass and increase of the LPL activity.

Objective To investigate the effect of Alzheimer' s beta-amyloid (Aβ) on the production and the translocation in cytoplasm of retinoid receptor-α (RXRα). MethodsN2awt cells were treated with Aβ peptide or amyloid protein precursor(APP695) transfection. The nucleus were separated from the cytoplasm by kit. The quantity of RXRα in the nucleus and cytoplasm was detected by Westernblot. The translocation of RXRα in the nucleus and cytoplasm of above N2awt cells or of the cortex cells in the brains of Alzheimer' s disease (AD) patients and their normal control groups was observed by immune fluorescence. ResultsIn N2awt cells, the increasing APP or Aβ had no significant effect on the production of RXRα but resulted in RXRα exporting into cytoplasm, the ratio of RXRα in cytoplasm increased from 3.2% (in control group) to 17.6% (in APP+ group) and from 3.8% (in control group) to 14.3% (in Aβ + group) respectively; compared with normal cortex cells, the translocation of RXRα in the cytoplasm of the cortex cells in the brains of AD increased significantly. ConclusionAβ may affect RXRα exporting into cytoplasm.

A novel method was established for the qualitative and quantitative determination of fatty acids in Channel Catfish muscle by gas chromatography-electron ionization-mass spectrometry (GC-EI-MS) after supercritical carbon dioxide fluid extraction (SFE-CO_2). The extraction parameters for the methodology were optimized). The optimal conditions were extraction pressure of 25 MPa at 45 ℃ and extraction time of 100 min at the rate of carbon dioxide 30 L/h. The fatty acids in the muscle oil were derived by boron-trifluoride method). The saponification time was 10 min, and the esterication time was 20 min. The obtained fatty acid methylesters were separated by gas chromatography using a HP-Innowax capillary column, and were detected by electron) ionization) mass spectrometry. Full scan mode and SIM mode were used for the qualitative and quantitative analysis), respectively. In the SIM mode, saturated fatty acids were determined with m/z 74, mono-unsaturated) fatty acids were determined with m/z 55, double-unsaturated fatty acids were determined with m/z 67, and polyunsaturated fatty acids were determined with m/z 79. The detection limits of 14 fatty acids were 2.2-20.0 μg/L(S/N=3)), and the quantitative limits were 7.39-59.85 μg/L(S/N=10). The recoveries fell in the range from 90.0% to 111.2%(n=4), and the relative standard deviation was between) 2.0% and 5.9%. This effective, sensitive and reproducible method can be used for the determination of fatty acids in Channel Catfish muscle sample.
