    Hydroxyproline concentration in soluble and insoluble material from serum treated with trichloroacetic acid in postpartum mice (1986)

    Details
    ISSN: 1420-9071
    Schlagwort(e): Hydroxyproline concentration ; serum ; trichloroacetic acid ; postpartum ; mice

    Thema: Biologie , Medizin
    Notizen: Summary The hydroxyproline concentration in both the soluble and insoluble material from trichloroacetic acid-treated serum from postpartum mice was determined. The hydroxyproline concentration in the insoluble material increased, but that in the soluble material did not increase during the uterine involuting period.

    Sleep-enhancing effects of far-infrared radiation in rats (1988)
    Springer
    International journal of biometeorology 32 (1988), S. 92-94 
    Details
    ISSN: 1432-1254
    Schlagwort(e): Far infrared ; Slow wave sleep ; Light period ; Circadian activity-rest cycle

    Thema: Geographie , Physik
    Notizen: Abstract Unrestrained male rats continuously exposed to far-infrared radiation exhibited a significant increase in slow wave sleep (SWS) during the light period but not in the dark period. The change was largely due to the elevated occurrence of SWS episodes but not to the prolongation of their duration. Paradoxical sleep was not affected throughout the observation period except for a significant decrease at the end of the dark period. Thus the far-infrared radiation exerted a sleep modulatory effect closely related to the circadian activity-rest cycle.

    The role of the anteroventral 3rd ventricle area in the osmotic control of paraventricular neurosecretory cells (1989)

    Notizen: Summary To obtain electrophysiological evidence of an involvement of the anteroventral 3rd ventricle (AV3V) area in the osmotic control of neurohypophysial hormone release, extracellular action potentials of paraventricular (PVN) oxytocinergic and vasopressinergic cells during osmotic stimulation induced by i.p. injection of 1.5 M-NaCl solution were obtained from urethane anesthetized AV3V-lesioned, intact and sham-lesioned lactating rats. In intact and sham-lesioned rats the electrical activities of both oxytocinergic and vasopressinergic cells increased in response to the i.p. injection of hypertonic saline. After electrolytic lesion of the AV3V, the responsiveness of both types of cells to osmotic stimuli was severely impaired, whereas oxytocinergic cells were still capable of responding to suckling stimuli by displaying high frequency discharges of action potentials preceding milk-ejection. These results provide electrophysiological evidence that destruction of the AV3V area selectively impairs osmoregulatory input to PVN neurones and that the area has osmosensitive elements which activate the PVN neurosecretory cells when plasma osmotic pressure rises.

    Facilitation of milk ejection-related activation of oxytocin-secreting neurones by osmotic stimulation in the rat (1987)
    Springer
    Experimental brain research 65 (1987), S. 312-316

    ISSN: 1432-1106

    Notizen: Summary Extracellular recordings were made from antidromically identified neurosecretory cells in the paraventricular nucleus of the hypothalamus in urethane-anesthetized lactating rats. Sixty-six percent of the rats tested (n=80) showed reflex milk ejections during suckling. Oxytocin neurones could be distinguished from other neurosecretory neurones by a characteristic high-frequency burst of spikes displayed before a reflex milk ejection. Twenty-three of the oxytocin neurones recorded from twenty-three individual animals were tested for the effect of intraperitoneal injection of 1.5 M NaCl (1 ml), which raised the plasma osmotic pressure from 299.3±2.4 (SE) mosmole/kg to 313.0±2.4 mosmole/kg. The injection significantly increased not only the firing rate of the oxytocin neurones (from 1.7±0.3 spikes/s to 4.9±0.6 spikes/s) but also the number of spikes per burst (from 53.6±7.4 to 75.5±7.5) and burst duration (from 3.38±0.22 s to 3.80±0.18 s). The amplitude of reflex milk ejection was also increased to 1.9 times. However, the injection did not change the interval between bursts. On the other hand, intraperitoneal injection of 0.15 M NaCl affected neither these parameters of oxytocin neurones nor the amplitude of milk ejection. Some of the antidromically identified neurones recorded in the rats which showed no detectable reflex milk ejection during suckling displayed intermitent bursts of action potentials. Ten of these neurones in ten individual rats were tested for the effect of 1.5 M NaCl. The number of spikes per burst was significiantly increased and reflex milk ejection was induced by the injection in eight of these rats. Then the bursts became milk ejection-related. These results indicate that increased plasma osmotic pressure influences the milk ejection reflex by enhancing the burst activity of oxytocin neurones which precedes reflex milk ejection.
