Abstract In order to investigate whether a calcium channel blocker could modulate the protein kinase C activity in normal and estradiol pretreated rat pituitary, female Wistar rats were treated or not (controls) with ± PN 200-110 (3 mg · kg−1 · day−1, sc) for 8 days or with estradiol cervical implants for 8 or 15 days, alone or in combination with PN 200-110 the last 8 days. Estradiol treatment induced a significant increase in plasma prolactin levels and pituitary weight. PN 200-110 administered to normal rats did not modify these parameters, whereas it reduced the effects of the 15 days estradiol treatment on prolactin levels (53.1 ± 4.9 vs 95.0 ±9.1 μg/l, p<0.0001) and pituitary weight (19.9 ± 0.4 vs 23.0 ± 0.6 mg, p <0.001), to values statistically comparable to those measured after 8 days of estradiol treatment. PN 200-110 alone did not induce any change in protein kinase C activity as compared with controls. In contrast, PN 200-110 treatment significantly counteracted the large increase in soluble activity and the decrease in the particulate one induced by estradiol between day 8 and day 15. We conclude that PN 200-110 opposed the stimulatory effects of chronic in vivo estradiol treatment on plasma prolactin levels and pituitary weight and that this regulation was related to a concomitant modulation of the protein kinase C activity.

Before And After

In the scope of studies that investigate the effects of manipulation in verbal antecedents upon the related non verbal behavior, the present study evaluated the effect of differential reinforcement of one response class (choice of phrases about positive aspects about reading, interpreted as tacts with positive qualifying autoclitics) upon other class (the choice of reading behavior), reinforcing choices of phrases about positive aspects of reading and observing its effects upon the emission of reading behavior. It were registered activities and photographs chosen before and after the training. During training, four phrases appeared in a computer screen and just the choice of one of them (related to reading) was reinforced with points. The results indicated an augment of the choices in reading behavior as well as in the time of reading for the majority of the participants and an augment of the choices of choosing photographs related to reading, when compared to the results of the baseline. The results are interpreted according to behavior verbally governed.
