Regions of specialization for water absorption across the skin of Bufonid and Ranid anurans were identified by immunohistochemistry and Western blot analysis, using antibodies raised against arginine vasotocin (AVT)-stimulated aquaporins (AQPs) that are specific to absorbing regions of Hyla japonica. In Bufo marinus, labeling for Hyla urinary bladder-type AQP (AQP-h2), which is also localized i...

OBJECTIVE To compare the pulmonary absorption characteristics of two insulin solutions-humalog (insulin lispro) and Novolin R (Biosynthetic Human insulin) with in vivo and in vitro methods. METHODS Investigate the pharmacodynamics in Sprague Dawley (SD) rat model (in vivo studies) and permeability across Rana catesbeiana pulmonary membrane (in vitro studies) of Biosynthetic Human insulin (BHI...

Cut fibers from Rana temporaria and Rana pipiens (striation spacing, 3.9-4.2 microns) were mounted in a double Vaseline-gap chamber and studied at 14 degrees C. The Ca indicator purpurate-3,3' diacetic acid (PDAA) was introduced into the end pools and allowed to diffuse into the optical recording site. When the concentration at the site exceeded 2 mM, step depolarizations to 10 mV were applied ...

This article considers the natural regulators of blood-sucking Simuliidae subzone mixed forests on territory Belarus and Ukraine. In forests, major preimaginal phases bloodsucking blackflies are microsporidia (Polidyspirenia simulii, Polidyspirenia sp., Thelohania fibrata, Amblyospora bracteata, A. varians), fungi mermithides (Gastromermis boophthorae). Caddisfly larvae (Hydropsyche angustipenn...

Seventeen kinds of enzymes and two kinds of blood proteins cxtracted from 1777 frogs of47 populations of Rana nigremacutata, 220 frogs of l2 populations ofR. brevipoda brevipodu and 340 frogs of 11 popuLations ef R. breviPoda Porosa were analyzed by the method ofhorizontal starch-gel electrophoresis. There were 7.6 phcnotypes produced by 4.1 alleles on the average at each of 28 leci. Thc gene f...

The order o f ossification of bones in the skeleton of Rana pipiens during larval growth and metamorphosis has been determined from observations on specimens fixed in 70% alcohol and stained with alizarin red S . The axial skeleton ossifies i n a generally cephalo-caudal sequence, beginning with the parasphenoid bone at Taylor-Kollros stages IV-IX, followed by vertebrae (V-IX) and then the uros...
