Background and Objective: Effects of electeromagnetic exposure on different parts of neruous system and memory of humans and animals has been established. In spite of important human studies, animal studies have been more precise and comprehensive. Extremely low frequency electromagnetic fields (ELF, <300Hz), have been reported to induce a variaty of behavioral and physiological function change...
Background & Aim: Peripheral cannabinoid and glycine receptors are involved in food intake regulation. This study was conducted to investigate the possible interaction between these two receptors in regulating food intake. Methods: This is an experimental study which was conducted on forty male Wistar rats. In the first phase of the experiment, the rats simultaneously received intraperitonea...
Two cases have been described, that of the marine planarian Bdelloura and that of the starfish Asterias forbesii, in which strychnine reverses reciprocal inhibition. These facts indicate that the nervous systems of these invertebrates function in a manner similar to those of the earthworm and vertebrates. Moreover, it would seem that strychnine acts upon some chemical component of the neuron wh...
Although （i） spinal cord disinhibition can cause spontaneous burst activities in the phrenic nerve and （ii） this propriospinal network be harnessed to allow diaphragm function after a injury, characteristics of are unclear. To characterize network, we cut isolated from neonatal rats aged 0-4 days into four blocks consisting three segments （C3-C5, T6-T8, L2-L4, L6-S2）, motor were recorded C4, T7...
1. Strychnine sulfate 0.000069 M decreased percentage attachment to the substratum by Amoeba proteus in 0.0029 M NaCl from 77.3 to 1.3, in 0.0029 M KCl from 40.8 to 2.5, in 0.002 M CaCl(2) from 73.3 to 68.0, in 0.002 M MgCl(2) from 85.5 to 83.3. 2. Frequency of ingestion of chilomonads by Amoeba proteus is increased by adding strychnine sulfate to solutions of NaCl, KCl, or CaCl(2). Frequency o...
