Effects of prenatal exposure to ethanol on the number of axons in the pyramidal tract of the rat.

We examined the effect of gestational ethanol exposure on the number of axons in the caudal pyramidal tract. Between gestational day (G) 6 and G21, inclusive, pregnant rats were fed a liquid ethanol-containing diet (Et), an isocaloric liquid control diet (Ct), or a diet of chow and water (Ch). On postnatal day 30, the offspring of these rats were killed and their caudal medullas were processed for electron microscopy.

Effects of 60 Hz electric and magnetic fields on maturation of the rat neopallium.

This study was undertaken to determine the effects of extremely low frequency (ELF; 60 Hz) electromagnetic (EM) fields on somatic growth and cortical development, as well as biochemical and morphological maturation, of the rat neopallium. On the fifth day of pregnancy, female rats were put in pairs into plastic cages that were housed in a specially constructed apparatus for irradiation under three separate sets of combination and intensity: 1) 1 kV/m and 10 gauss; 2) 100 kV/m and 1 gauss; and 3) 100 kV/m and 10 gauss. The dams were exposed for 23 h daily, from days 5 through 19 postconception, after which they were returned to cages outside the exposure apparatus until they littered.

Effects of 60 Hz electric and magnetic fields on the development of the rat cerebellum.

The effects of extremely low frequency (ELF) electromagnetic (EM) fields on the maturation of the rat cerebellum were studied. Newborn rats were exposed to 60 Hz electric and magnetic fields under three different combinations in a specially constructed apparatus. The pups were irradiated for 7-8 h daily, with a 30-min interruption for nursing.

Effect of prenatal exposure to ethanol on the ultrastructure of layer V of mature rat somatosensory cortex.

Recent data have shown that the structure and function of layer V pyramidal neurons, e.g. corticospinal neurons, is altered by prenatal exposure to ethanol.

Immunocytochemical localization and immunological characterization of vitamin D-dependent calcium-binding protein in the bullfrog cerebellum.

Antiserum prepared against rat renal calcium-binding protein (CaBP) was used with the unlabeled antibody peroxidase-antiperoxidase (PAP) technique to localize the 28,000 molecular weight CaBP in the cerebellum of the bullfrog, Rana catesbeiana. Whole brains of premetamorphic tadpoles and adults were fixed in Bouin's solution for 2 or 24 h and embedded in paraffin. 8-microns parasagittal sections were prepared and treated by the PAP method.
