WebBackground: Chronic sensory-predominant polyneuropathy (PN) is a common clinical problem confronting neurologists. Even with modern diagnostic approaches, many of … WebThe cryptonephric Malpighian tubules within the rectal complex are bathed in fluid within a functional compartment, the perinephric space, which is separate from the haemolymph. In this study, the scanning ion-selective electrode technique (SIET) was used to measure transport of Na+ and K+ across the rectal complex and across multiple regions ...

Webknown as ‘cryptonephric complex’. This system facilitates the reabsorption of water and, therefore, is more highly developed in insects that feed on dry substances or live in a relatively dry environment and therefore need to retain water [4,7]. Notably in beetles that feed on dry substance, a special arrangement WebMas-DPII has no effect on fluid transport across the larval cryptonephric complex. M. sexta diuretic hormone (Mas-DH) and CRF-related insect diuretic peptides from Acheta domesticus, Locusta migratoria, and Periplaneta americana also cause similar increases in the production of cyclic AMP by the Malpighian tubules of both larval and adult M. sexta.
WebThe rectal or cryptonephric complex is a structure in which the terminal parts of the Malpighian tubules are closely associated with the rectum. It withdraws water from the rectal contents, thereby limiting fecal water loss, and is even capable of withdrawing water from unsaturated air. Webcryptonephridial system An arrangement of the excretory system in certain beetles and lepidopteran larvae in which the distal blind endings of the Malpighian tubules are held against the wall of the rectum by a perinephric membrane.
WebMay 1, 1993 · It appears that in this complex Mas-DH is acting on a Na + /K + /2Cl − co-transporter, presumably on the basal membrane of the cryptonephric Malpighian tubules, because Mas-DH-stimulated fluid absorption by the cryptonephric complex is inhibited by bumetanide or the removal of Cl -, Na + or K + from the haemolymph side of the tissue.

Extracts of the brain/corpora cardiaca/corpora allata (Br/CC/CA) complex of Manduca sexta larvae elicit an antidiuretic effect, measured by an increase in fluid reabsorption across the cryptonephric complex of larval M. sexta.
