    Notes: Summary Previous studies indicate that the pineal gland alters prolactin secretion, and it was suggested that at least part of the effect of the pineal hormone melatonin on prolactin release may be mediated by the hypothalamic structures. In this study, pinealectomy and lesions of the suprachiasmatic nuclei were found to alter serum levels of prolactin in the same direction, an effect that was counteracted by daily afternoon melatonin administration. Melatonin, but not other pineal indoles, also prevented sulpiride-induced prolactin secretion in pinealectomized or suprachiasmatic nuclei-lesioned and ovariectomized rats, which suggested that the pineal gland can modulate prolactin secretion by acting through a dopamine mechanism independent of hypothalamic suprachiasmatic structures.

    ZnO transducers on InSb for low-temperature ultrasonics (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 5199-5201

    Notes: A reproducible method for the fabrication of ZnO transducers on InSb substrates is described. These transducers are being used for ultrasonic attenuation measurements over a wide low-frequency range (90–600 MHz) at very low temperatures(0.1–4.2 K). They have been characterized by their x-ray diffraction patterns, their insertion loss, and their contribution to the acoustic attenuation in InSb at low temperatures.

    Effects of Pinealectomy and Continuous Light on Mating Behavior of Male Rats (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of pineal research 6 (1989), S. 0

    Notes: The role of pinealectomy and continuous light in the regulation of sexual activity was studied in the male rat. The parameters studied in order to evaluate the sexual behavior were initial latency, ejaculatory latency, refractory period, neuromotor activity, number of ejaculations, intromissions (false, real, and total) and percentage of ejaculating male rats. Pinealectomy as well as continuous light induced a marked facilitation of the animal's sexual behavior as shown by the shorter initial latency and refractory period, as well as by the increase in the number of intromissions (real and total) showed in the tests. However, the ejaculatory latencies did not change. There was also an enhanced neuromotor activity. An increase in the number of ejaculations as well as in the percentage of ejaculating male rats was produced by continuous light. From the results it is concluded that pineal hormones play an important role in male rat sexual behavior.
