17. Adenosine 3′,5′-Monophosphate in Rat Pineal Gland: Increase Induced by Light

Author

Ebadi, Manuchair S., Weiss, Benjamin, and Costa, Erminio

Abstract

Rats were maintained in alternating periods of 12 hours of light and 12 hours of darkness. The concentration of adenosine 3′,5′-monophosphate in pineal gland was six times higher at the end of the light period than at the end of the period of darkness. This effect of light was abolished in blinded animals.

18. Adenyl Cyclase Activity in Rat Pineal Gland: Effects of Chronic Denervation and Norepinephrine

Author

Weiss, Benjamin and Costa, Erminio

Abstract

Adenyl cyclase activity in the pineal gland of rats was determined by measuring the rate of formation of radioactive cyclic 3′,5′-adenosine monophosphate from 14C-labeled adenosine triphosphate. Norepinephrine added in vitro to pineal homogenates enhanced this activity, while denervation of the pineal gland by superior cervical ganglionectomy did not significantly reduce it. The enzyme in these denervated glands was more responsive to the stimulatory effects of norepinephrine.

Abstract

Magnetic fields are proposed to have played a critical role in some of the most enigmatic processes of planetary formation by mediating the rapid accretion of disk material onto the central star and the formation of the first solids. However, there have been no experimental constraints on the intensity of these fields. Here we show that dusty olivine-bearing chondrules from the Semarkona meteorite were magnetized in a nebular field of 54 ± 21 μT. This intensity supports chondrule formation by nebular shocks or planetesimal collisions rather than by electric currents, the x-wind, or other mechanisms near the sun. This implies that background magnetic fields in the terrestrial planet-forming region were likely 5-54 μT, which is sufficient to account for measured rates of mass and angular momentum transport in protoplanetary disks., Thomas F.
