This work deals with study of role of the hairplate and of campaniform sensillae (CS) on legs of the cockroach Periplaneta americana in the system of walking control. Three receptors were shown to induce their regulatory, correctional effect on the rhythm of the cockroach steps depending on the external circumstances. These effects are mainly realized only(More)
Isatin, an endogenous indole, has previously been shown to inhibit atrial natriuretic peptide (ANP)-stimulated particulate guanylate cyclase activity. Here, it was shown that it can be transported to human platelets where it inhibited nitric oxide (NO)-stimulated soluble guanylate cyclase activity obtained from human platelets. The effect was most(More)
We report here our studies of the characteristics of the structural-functional organization of the leg apparatus of the dragonfly Aeshna grandis, in larvae of the final instar, whose legs have a locomotor function, and in adult winged individuals (imagoes), whose legs have lost their locomotor function and are used mainly as traps to catch prey in the air.(More)
Topographic anatomy of ascending (AN) and descending (DN) neurons of the supraesophageal and thoracic ganglia in the nervous system of winged insects (Pterygota), representatives of the infraclasses Palaeoptera (Odonata, Aeschna grandis, dragonfly) and Neoptera (Blattoptera, Periplaneta americana, cockroach), was studied. These insects differ in ecological(More)
