Abstract

In this study we investigated the prospect of microwave‐induced alteration of ^45^Ca^2+^ efflux from rat neural tissue at low pulse repetition frequencies and low power densities under in vitro conditions. Rat cerebral tissue, preloaded with ^45^Ca^2+^, was exposed to pulsed‐microwave radiation (1‐GHz carrier frequency) according to one of several PRF‐power density exposure schemes: 16 Hz at 0.5, 1.0, 2.0, or 15 mW/cm^2^, or 32 Hz at 1.0 or 2.0 mW/cm^2^ average power density. Measurements of radioactivity in the efflux medium and in the tissue sample were used to calculate an efflux value for each sample. The results indicate that the radiation conditions used did not alter calcium efflux in rat brain tissue.

N-Arylcarbamoylpyrazolines with various substituents at the para position of the carbamoyl benzene ring inhibited ATP-dependent Ca2+-uptake in synaptosomes prepared from the rat brain. The activity of these compounds was evaluated as log( 1/15,), the reciprocal logarithm of half inhibitory concentra

Background: Bis-diamine induces cardiac defects, including conotruncal anomalies in rat embryos when the agent is administered to the mother. To evaluate the teratogenic effects and mechanism of bis-diamine, we performed morphological and immunohistochemical analyses of early rat embryos cultured in
