The work is devoted to the methods of obtaining the thermosensitive copolymeric hydrogels based on the NIPAAm with acrylic acid and its derivatives such as acrylamide, acrylonitrile, and methylacrylate. The mechanisms of thermoinitiated phase transitions in hydrogel matrices and the regularities of the thermoinitiated release of model compounds and drugs (aniline, novocaine, and sodium diclofenac) from copolymeric hydrogel are investigated.

The method of diagnostics of aromatic compounds on the example of novocaine, aspirin and anthracene is presented. The method is based on optical detection of photoluminescence spectra at ultraviolet laser (266 nm) excitation. Employing this method the photoluminescence spectra are obtained which allows one to establish the differences of the composition and structure of compounds. The developed method can be used for analysis the quality of the large class of luminescent bioactive structures under the ultraviolet radiation. (authors)

To study influence parapancreatic microirrigation on morphological and functional condition of a pancreas and transformations of enzymatic activity of blood serum and enzymatic activity of lymph of a chest lymphatic channel after an operative trauma of a duodenum. Research is executed on 140 not purebred dogs which have been divided into six groups and united in two series. In the first series (30 dogs) were studied changes pancreatic exosecretion in the postoperative period of resection of duodenum (group 1.1), in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 1.2) and after resection of duodenum with application parapancreatic microirrigation (group 1.3). In the second series (110 dogs) were studied frequency of development of acute pancreatitis, enzymatic activity of blood serum and enzymatic activity of lymph of thoracal lymphatic duct after resection of duodenum (group 2.1) and in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 2.2) and after resection of duodenum with application parapancreatic microirrigation (group 2.3). Application parapancreatic microirrigation does not lead to oppression pancreatic exosecretion at the first o'clock after duodenotomy, and substantially reduces the pancreatic hypersecretion observed in the postoperative period of resection of a duodenum. In addition, application parapancreatic microirrigation reduces frequency of development of acute pancreatitis and promotes less expressed increase enzymatic activity of blood serum and enzymatic activity of lymph thoracal lymphatic duct at development of the given complication after operational trauma of duodenum in comparison with resection of duodenum and after a resection of a duodenum executed against infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain.

Under analysis are etiology, clinical picture and diagnosis of a septic thrombosis of cavernous sinuses in 28 patients. The authors have shown the interrelationship between local manifestations of the disease, injuries of the brain and its sheaths and septic complications (abscessing pneumonia as the most severe of them). A scheme of the complex treatment of patients with thrombosis of the cavernous sinus is proposed. The leading role in this treatment is played by intracarotid infusion of antibiotics in combination with anticoagulant drugs, vasodilatatory agents and novocaine as well as the therapy of septic complications (abscesses of the face and hairy part of the head, meningoencephalitis, pneumonia).
muscles during ischaemia, as observed by Matthews, weight discrimination and the capability of hitting targets with objects of different weights were not significantly altered, even during the painful phase of fatigue. V - A nervus digitalis volaris proprius was stimulated with A.C. current of 60 cycles at a just tolerable intensity. After three minutes of stimulation the initial paresthesias and pain had almost disappeared, and were followed by numbness and increased sensory thresholds in the field of distribution of that nerve. A few seconds after stimulation was interrupted, sensation was again normal in that field. Comparable phenomena were observed under normal conditions, in the absence of ischaemia. VI - Novocaine block of a finger in the ischaemic side did not influence "pins and needles", which appear after arrest of circulation is released. Therefore, the field of origin of the "pins and needles" does not seem to be the receptor field (Weddell and Sinclair but more probably the nerve fibers themselves (Lewis, Kugelberg. VII - As is well known, "pins and needles" are accentuated by tapping the fingers and, much less, by pressing them. Thermic and painful stimulation have no effect on these paresthesias. Tapping would probably stimulate muscle and touch receptors. On the basis of our observations and Kugelberg's physiological analysis, we are inclined to consider the nerve fibers of these receptors as the field of origin of these paresthesias. VIII - No accentuation of "pins and needles" was found by (a tapping an anesthetized finger, nor (b pressing the muscles; but (c tapping the fingers does reinforce these paresthesias, also during the phase when simple pressure has the opposite effect of extinguishing them. So, it seems that accentuation is related to specific nerve fibers, but it is only brought about when a special function is at play. Therefore, enhancement of those paresthesias is limited to the correlated function of proprioceptors and touch receptors
