Abstract
BACKGROUND The high mortality rate of patients with acute myocardial infarction (AMI) remains the most pressing issue of modern cardiology. Over the past 10 years, there has been no significant reduction in mortality among patients with AMI. It is quite obvious that there is an urgent need to develop fundamentally new drugs for the treatment of AMI. Angiotensin 1-7 has some promise in this regard. OBJECTIVE The objective of this article is analysis of published data on the cardioprotective properties of angiotensin 1-7. METHODS PubMed, Scopus, Science Direct, and Google Scholar were used to search articles for this study. RESULTS Angiotensin 1-7 increases cardiac tolerance to ischemia/reperfusion and mitigates adverse remodeling of the heart. Angiotensin 1-7 can prevent not only ischemic but also reperfusion cardiac injury. The activation of the Mas receptor plays a key role in these effects of angiotensin 1-7. Angiotensin 1-7 alleviates Ca2+ overload of cardiomyocytes and reactive oxygen species production in ischemia/reperfusion (I/R) of the myocardium. It is possible that both effects are involved in angiotensin 1-7-triggered cardiac tolerance to I/R. Furthermore, angiotensin 1-7 inhibits apoptosis of cardiomyocytes and stimulates autophagy of cells. There is also indirect evidence suggesting that angiotensin 1-7 inhibits ferroptosis in cardiomyocytes. Moreover, angiotensin 1-7 possesses anti-inflammatory properties, possibly achieved through NF-kB activity inhibition. Phosphoinositide 3-kinase, Akt, and NO synthase are involved in the infarct-reducing effect of angiotensin 1-7. However, the specific end-effector of the cardioprotective impact of angiotensin 1-7 remains unknown. CONCLUSION The molecular nature of the end-effector of the infarct-limiting effect of angiotensin 1-7 has not been elucidated. Perhaps, this end-effector is the sarcolemmal KATP channel or the mitochondrial KATP channel.

Abstract
A comparative analysis of the infarct-limiting activity of δ- and κ-opioid receptors (OR) agonists was carried out on a model of coronary occlusion (45 min) and reperfusion (120 min) in male Wistar rats. We used selective δ2-OR agonist deltorphin II (0.12 mg/kg), δ-OR agonists BW373U86 and p-Cl-Phe DPDPE (0.1 and 1 mg/kg), selective agonists of δ1-OR DPDPE (0.1 and 0.969 mg/kg), κ1-OR U-50,488 (0.1 and 1 mg/kg), κ2-OR GR-89696 (0.1 mg/kg), and κ-OR ICI-199,441 (0.1 mg/kg). All drugs were administered intravenously 5 min before reperfusion. Deltorphin II, BW373U86 (1 mg/kg), p-Cl-Phe DPDPE (1 mg/kg), U-50,488 (1 mg/kg), and ICI-199,441 had a cardioprotective effect. The most promising compounds for drug development are ICI-199,441 and deltorphin II.

Abstract
An analysis of published data and the results of our own studies reveal that the activation of a peripheral δ2-opioid receptor (δ2-OR) increases the cardiac tolerance to reperfusion. It has been found that this δ2-OR is localized in cardiomyocytes. Endogenous opioids are not involved in the regulation of cardiac resistance to reperfusion. The infarct-limiting effect of the δ2-OR agonist deltorphin II depends on the activation of several protein kinases, including PKCδ, ERK1/2, PI3K, and PKG. Hypothetical end-effectors of the cardioprotective effect of deltorphin II are the sarcolemmal KATP channels and the MPT pore.

Abstract
Purpose. This work investigates the relations between the production of reactive oxygen species (ROS) by epicardial adipose tissue (EAT) adipocytes and parameters of glucose/insulin metabolism, circulating adipokines levels, and severity of coronary atherosclerosis in patients with coronary artery disease (CAD); establishing significant determinants describing changes in ROS EAT in this category of patients. Material and methods. This study included 19 patients (14 men and 5 women, 53−72 y.o., 6 patients with diabetes mellitus type 2; 5 patients with prediabetes), with CAD, who underwent coronary artery bypass graft surgery. EAT adipocytes were isolated by the enzymatic method from intraoperative explants obtained during coronary artery bypass grafting. The size of EAT adipocytes and ROS level were determined. Results. The production of ROS by EAT adipocytes demonstrated a direct correlation with the level of postprandial glycemia (rs = 0.62, p < 0.05), and an inverse correlation with serum adiponectin (rs = −0.50, p = 0.026), but not with general and abdominal obesity, EAT thickness, and dyslipidemia. Regression analysis demonstrated that the increase in ROS of EAT adipocytes occurs due to the interaction of the following factors: postprandial glycemia (β = 0.95), postprandial insulin (β = 0.24), and reduced serum adiponectin (β = −0.20). EAT adipocytes in patients with diabetes and prediabetes manifested higher ROS production than in patients with normoglycemia. Although there was no correlation between the production of ROS by EAT adipocytes and Gensini score in the total group of patients, higher rates of oxidative stress were observed in EAT adipocytes from patients with a Gensini score greater than median Gensini score values (≥70.55 points, Gr.B), compared to patients with less severe coronary atherosclerosis (<70.55 points, Gr.A). Of note, the frequency of patients with diabetes and prediabetes was higher among the patients with the most severe coronary atherosclerosis (Gr.B) than in the Gr.A. Conclusions. Our data have demonstrated for the first time that systemic impairments of glucose/insulin metabolism and a decrease in serum adiponectin are significant independent determinants of oxidative stress intensity in EAT adipocytes in patients with severe coronary atherosclerosis. The possible input of the interplay between oxidative stress in EAT adipocytes and metabolic disturbances to the severity of coronary atherosclerosis requires further investigation.

Abstract
BACKGROUND Age and diabetes are risk factors for arterial hypertension. However, the relationship between age, connective tissue growth factors, vascular aging and arterial hypertension while on a the high-carbohydrate high-fat diet (HCHFD) remains poorly understood. PURPOSE To estimate the relationship between humoral factors, the morphological changes of aorta and impaired blood pressure regulation under the influence of age and a HCHFD. METHODS A study was carried out in male Wistar rats, which were divided into the following groups: 1st (n = 15) - naive young rats; 2nd (n = 15) - young rats, exposed to HCHFD; 3rd (n = 14) - naive old rats; 4th (n = 12) - old rats exposed to HCHFD. The age of old rats was 540 days, and young rats 150 days at the end of the diet. HCHFD contained proteins 16%, fats 21%, carbohydrates 46%, including 17% fructose, 0.125% cholesterol, 90 days. Blood pressure and body weight were measured weekly, carbohydrate metabolism, histological signs of changes in the aorta, serum transforming growth factor-β (TGF-β), connective tissue growth factor (CTGF), fibronectin, and endothelin-1 levels were determined one week after the onset of diet. RESULTS The severity of arterial hypertension and its histological signs in the aortic wall was found to be most pronounced in elderly rats kept on a HCHFD. In young rats kept on a HCHFD, arterial hypertension was transient. An increase in systolic blood pressure has a positive correlation with the degree of obesity, serum fibronectin, and endothelin-1 content, and impaired carbohydrate metabolism. The rise in diastolic blood pressure has a positive correlation with the serum CTGF, endothelin-1, fibronectin levels and aortic wall thickness, and impaired carbohydrate metabolism. A rise in the serum concentration of fibronectin was also associated with increased endothelin-1, TGFβ and CTGF serum levels. CONCLUSION This study indicated that an increase in blood pressure in old rats with a high-carbohydrate high-fat diet is due to a disturbance of a structure of the vascular wall, the release of fibronectin, which can occur under the influence of carbohydrate metabolism disorders, endothelin-1, TGFβ and CTGF.

Abstract
Takotsubo syndrome (TS) is a rare but dangerous disease that can be fatal. The pathogenesis of TS is not well understood because there is no animal model of TS that fully mimics TS. It has now been documented that stress exposure (24 h) of rats induced the state which is similar TS in human: contracture damage of myofibrils, elevation of the serum creatine kinase MB level, increased 99mTc-pyrophosphate (99mTc-PYP) accumulation in the heart, QTc interval prolongation, and contractility dysfunction of the heart. Immobilization stress resulted in an increase in coronary blood flow. Emotional stress increased the serum catecholamine level. Blockade of β1-adrenergic receptor (AR) prevented stress-induced cardiac injury (SICI). Blockade of β2-AR aggravated stress-induced cardiac injury. Stimulation of β2-AR increased cardiac tolerance to stress. Inhibition of β3-AR, α1-AR had no effect on SICI. Blockade of peripheral muscarinic receptors or α2-AR aggravated SICI. Pretreatment with the selective β1-AR antagonist atenolol attenuates stress-induced cardiac contractility dysfunction, but recovery of cardiac contractility is not complete. There is indirect evidence that circulating catecholamines play an important role in SICI. Consequently, the activation of β1-AR plays a significant role in SICI. However, there are other receptors which are also involved in SICI and require further investigation.

Abstract
A humoral mechanism of cardioprotection by remote ischemic preconditioning (RIP) has been clearly demonstrated in various models of ischemia-reperfusion including upper and lower extremities, liver, and the mesenteric and renal arteries. A wide range of humoral factors for RIP have been proposed including hydrophobic peptides, opioid peptides, adenosine, prostanoids, endovanilloids, endocannabinoids, calcitonin gene-related peptide, leukotrienes, noradrenaline, adrenomedullin, erythropoietin, apolipoprotein, A-I glucagon-like peptide-1, interleukin 10, stromal cell-derived factor 1, and microRNAs. Virtually, all of the components of ischemic preconditioning's signaling pathway such as nitric oxide synthase, protein kinase C, redox signaling, PI3-kinase/Akt, glycogen synthase kinase β, ERK1/2, mitoKATP channels, Connexin 43, and STAT were all found to play a role. The signaling pattern also depends on which remote vascular bed was subjected to ischemia and on the time between applying the rip and myocardial ischemia occurs. Because there is convincing evidence for many seemingly diverse humoral components in RIP, the most likely explanation is that the overall mechanism is complex like that seen in ischemic preconditioning where multiple components are both in series and in parallel and interact with each other. Inhibition of any single component in the right circumstance may block the resulting protective effect, and selectively activating that component may trigger the protection. Identifying the humoral factors responsible for RIP might be useful in developing drugs that confer RIP's protection in a more comfortable and reliable manner.

Abstract
The active ingredient extracted from the peat humic substances was characterized by physicochemical parameters evaluated by UV- and IR-spectroscopy, titration, and elemental (C, H, N) analysis. The cardiovascular effects of this ingredient were examined on isolated Langendorff-perfused rat heart. It was found that the active substance in a concentration range of 0.01-0.1 mg/ml produced a vasodilating effect; in addition, it decreased the end-diastolic and left-ventricular developed pressures.

Abstract
CB receptor agonist HU-210 exhibits an infarction-limiting effect during in vitro reperfusion of the heart after focal ischemia. This effect is paralleled by a decrease in left-ventricular developed pressure and double product. In addition, HU-210 reduces end-diastolic pressure during the reperfusion period, which indirectly attests to reduced Ca2+ overload of cardiomyocytes.

Ischemic postconditioning was modeled by 3 cycles of reperfusion (30 sec) and ischemia (30 sec). Cardiomyocyte necrosis was assessed by the level of creatine phosphokinase in the perfusate. Postconditioning reduced the release of creatine phosphokinase from the heart by 30%. The cardioprotective effect of ischemic postconditioning was eliminated after inhibition of protein kinase C with cheleritrin or after blockade of δ-isoform of protein kinase C with rottlerin. These findings attest to participation of protein kinase C-δ in the realization of the cardioprotective effect of postconditioning.

Abstract
Remote ischemic preconditioning prevents reperfusion cardiomyocyte apoptosis and has the infarct-limiting effect which is maintained in the experiments on the isolated perfused heart. Remote preconditioning promotes to recovery the contractility of the heart during reperfusion, but did not affect the incidence of occlusion and reperfusion of ventricular arrhythmias. Remote preconditioning has a mild anti-inflammatory effect. Presented article is a review and formulated conclusions based on the published literature data.

Abstract
We studied the effects of μ-opioid receptor activation in vivo and in vitro on the tolerance of isolated perfused rat heart to global ischemia (45 min) and reperfusion (30 min). Stimulation of μ-receptors in vivo by intraperitoneal administration of μ-opioid receptor agonist DAMGO (0.1 mg/kg) reduced reperfusion release of creatinine phosphokinase and promoted aggravation of postischemic systolic and diastolic dysfunction of the isolated heart. Activation of μ-opioid receptors in vitro by addition of selective agonist DAMGO in a concentration of 170 nM to perfusion solution had no effect on necrotic death of cardiomyocytes and aggravated reperfusion stunning of the heart.

Abstract
Protein kinase Cepsilon (PKCepsilon) is a target for reactive oxygen species (ROS). It is activated with reaction products of OH* with phospholipids, which presumably include hydroperoxides of fatty acids or alkylperoxy radicals. Activation of PKCs with reactive oxygen species promotes to mito-K(ATP) channel opening and MPT pore (mitochondrial permeability transition pore) closing thereby it is increasing the resistance of cardiomyocytes to hypoxia-reoxygenation. P38 kinase and tyrosine kinases are targets of ROS. Hydroxyl radical or signaling molecules, resulting from its metabolism, may contribute to the activation of p38-kinase that increases the cardiac tolerance to the impact of ischemia-reperfusion. Src tyrosine kinase and P13-kinase apparently are not targets of ROS. The cardioprotective effect of ROS may be due to the activation of transcription factors NFkappaB and CREB.

Abstract
In Russia inhospital lethality after acute myocardial infarction is 16.5-16.7%. The part of patients perishes even after recanalisation of infarct-related coronary artery as a result of reperfusion cardiac injury. Experimental data indicate that adenosine receptor agonists and opioids can prevent reperfusion damages of heart that is mimic postconditioning phenomena. Data of clinical observation show that adenosine during intravenous infusion or intracoronary administration during thrombolysis or percutaneous coronary intervention exert infarct reducing effect and eliminate manifestation of of "no-reflow" phenomenon. Clinical data indicate that morphine is able to prevent cardiac reperfusion injury in human. Thus, analysis of published data testifies that adenosine and opioid receptor agonists can be prototype for development of drugs for prophylaxis of reperfusion heart injury.

Abstract
Reactive oxygen species (ROS) are triggers of ischemic preconditioning (IP). On the role of intracellular messengers of such cardioprotective effect of preconditioning claim: O2*, H2O2, OH*. However, we cannot exclude the possibility that other reactive oxygen metabolites also involved in the IP. Presented data suggest that IP enhances the production of ROS. The source of ROS may be mitochondrial respiratory chain and NADPH oxidase. Exogenous reactive oxygen species (O2*, H2O2) mimic the cardioprotective effect of preconditioning. Preconditioning prevents free radical damage of the heart during ischemia-reperfusion. The protective effect of IP is the consequence of reducing the production of ROS or the result of increased formation of endogenous antioxidants. Antioxidant enzymes are not involved in the protective effect of IP. Cardioprotective effect of many compounds (bradykinin, opioids, acetylcholine, phenylephrine, tumor necrosis factor-α, volatile anesthetics, protonophores, diazoxide, angiotensin II) depends on the increased production of ROS.

Abstract
Investigated the involvement of the endogenous opioid agonists attack in the implementation of the cardioprotective effect of postconditioning, playing with the model of isolated perfused on Langendorf rat heart. It is established that this phenomenon occurs when using three sessions reperfusion (30 s) and ischemia (30 s) played at the end of the period 45-min global ischemia. Using the selective blocker of different subtypes of opioid receptors, which was added in perfusion solution in early reperfusion period, found that the stability of the heart to action ischemia-reperfusion in ischemic postconditioning is implemented through the activation of the Delta-1 opioid receptor. Suggests that the mechanism cardioproteguoe phenomenon of postconditioning significant role belongs synthesized in the myocardium of endogenous opioids.

Abstract
It was established that short-term ischemia/reperfusion evokes an increase in myocardial tissue of enkephalin levels. A blockade of delta-opioid receptors abolishes the cardioprotective effect of ischemic preconditioning both in vivo and in vitro. An inhibition of kappa-opioid receptors abolishes the cardioprotective effect of ischemic preconditioning only in vitro. Agonists of mu-, delta1- delta- and kappa1-opioid receptors mimic the cardioprotective effect of preconditioning. Consequently, it can be argued that endogenous opioid peptides are triggers of ischemic preconditioning.

Abstract
Adaptation to cold promotes an increase in blood T3 and T4 levels in men and animals. The long-term cold exposure can induce a decrease in concentration of serum total and free T3 in human due to an enhancement of this hormone clearance. Endogenous catecholamines during adaptation to cold raise iodothyronine deiodinase D2 activity in brown fat due to α1-adrenergic receptor stimulation. Triiodothyronine is an inductor of iodothyronine deiodinase expression in brown fat, liver and kidney. Iodothyronine deiodinase D2 plays an important role in adaptation of organism to cold contributing to the high adrenergic reactivity of brown fat. At adaptation to cold T3 interacts with T3Rβ, it is formed T3Rβ-RXR complex, which binds to DNA with following transcription of UCP-1 and UCP-3 genes and UCP-1 and UCP-3 protein synthesis and uncoupling oxidative phosphorylation and an increase in heat production, where T3Rβ is T3-receptor-β, RXR is retinoid X-receptor, UCP is uncoupling protein. Triiodothyronine contributes to normal response to adrenergic agents of brown fat due to T3Rα activation. Sympatho-adrenomedullary and thyroid systems act as synergists in adaptation to cold.

Abstract
Parameters of respiration, transmembrane potential, and Ca(2+)-binding capacity of mitochondria isolated from Langendorff-perfused hearts of rats adapted to normobaric hypoxia were analyzed. Ischemia and reperfusion modeling in intact and adapted animals reduced Ca(2+)-binding capacity of mitochondria, which indicated increased sensitivity of mitochondrial permeability transition pores (MPTP) to calcium ions. These changes were accompanied by a decrease in transmembrane potential, ADP/O coefficient (ratio of added ADP to oxygen consumption in State 3), and inhibition of State 3 respiration. At the same time, adaptation attenuated the negative effect of ischemia and reperfusion on the functional state of mitochondria.

Abstract
Habitation within the polar circle increases cardiovascular mortality rate and particularly increases mortality as a result of coronary events. The main reason of elevation of mortality from these diseases is a dyslipidemia which developed more among alien population residing long time in Far North. Dyslipidemia is less found among aboriginal population of Arctic Circle keeping traditional way of life and respectively it is low rate of mortality from coronary heart disease. The data showed that low rate of dyslipidemia among aboriginal population of North regions depends on fish consumption which is high content of Ω3-polyunsaturated fatty acids.

Abstract
Authors submitted an analysis of papers given up an involvement of protein kinases in heart ischemic postconditioning. This analysis of literature source allowed to authors affirms that signaling system of postconditioning can involve kinases: PKC, PI3K, Akt, MEKl/2, ERK1/2, MTOR, p70s6K, GSK3b, PKG and also eNOS, NO, GC, motoKATP channel, ROS, MPT pore. At the same time it is unclear a real contributions of kinases mTOR, p70s6, AMPK and GSK3b in the mechanism of infarct limiting impact of postconditioning. It is required a further study of the chain of signaling events following JAK2 and p38 kinase activation. The knowledge of Ras and Raf-1 role in postconditioning has hypothetical character. The tyrosine kinase significance in postcondi-tioning is unclear, particular Src kinase, which plays an important role in the regulation of cardiac tolerance to an impact of ischemia and reperfusion.

Abstract
Irreversible cardiomyocyte damage was induced by 45-min global ischemia followed by 30-min reperfusion in Langendorff-perfused isolated rat heart. Cell damage was assessed by the release of creatine phosphokinase into the perfusate. The hearts were subjected to the following postconditioning protocols: 1) three cycles of 10-sec reperfusion and 10-sec ischemia, total cycle time 20 sec; 2) six cycles of 10-sec reperfusion and 10-sec ischemia, total cycle time 20 sec; 3) three sessions of 20-sec reperfusion and 20-sec ischemia, total cycle time 40 sec; 4) 6 cycles of 20-sec reperfusion and 20-sec ischemia, total cycle time 40 sec; 5) 3 cycles of 30-sec reperfusion and 30-sec ischemia, total cycle time 60 sec. It was found that only postconditioning with a total cycle time of 40 sec or 60 sec prevents myocardial reperfusion injury.

Abstract
The role of cyclic nucleotides (cAMP, cGMP) and Ca(2+)-ATPase of the sarcoplasmic reticulum in the mechanism of cardioprotective effects of selective δ(1)- and κ(1)-opioid receptor agonists DPDPE and U-50488 was studied under conditions of global ischemia and reperfusion of isolated and perfused rat heart. Activation of both types of opioid receptors 2-fold reduced the reperfusion release of creatine phosphokinase. The cardioprotective effect of U-50488 was paralleled by a 2-fold decrease in cAMP content in the myocardium, while DPDPE did not modify the content of cAMP throughout the experiment. None of these substances changed the content of cGMP in the myocardium. The cardioprotective effect of DPDPE was not observed after inhibition of sarcoplasmic reticulum Ca(2+)-ATPase with cyclopiazonic acid. The cardioprotective effect of U-50488 was associated with reduction of cAMP level in the myocardium, while the cytoprotective effect of DPDPE was mediated by opioidergic modulation of Ca(2+) transport at the level of the sarcoplasmic reticulum.

Abstract
From 1984 in N.N. Burdenko Surgical clinic of I.M. Sechenov MMA more than 500 horizontal gastroplasties (HGP) were performed for the treatment of patients with extreme degree of alimentary-constitutional obesity. In 1996 for the first time in our country HGP was performed, including laparoscopic method, with use of regulated silicon bandage "Lap-Band" (LB) made by "Bioenterics", USA. Laparoscopic HGP was performed in 29 patients (7 males, 22 females), aged from 23 to 60 years, mean age was 34.2 +/- 10 years. Minimal body weight was 85 kg, maximal--180 kg, mean--131 +/- 27.2 kg. Mean body mass index was 47 +/- 9.9 kg/m2. Open operations were performed in 14 cases, laparoscopic operations--in 15 cases. 11 laparoscopies were performed in initial stages in very stout patients and in the absence of laparoscopic equipment. In 3 cases the conversion from laparoscopic to open operation was necessary: in 1st case because of hemorrhage from lesser omentum's vessels, when hemostasis cannot be performed by laparoscopy; in 2nd case as a result of bronchospasm associated with tense pneumoperitoneum in the patient with bronchial asthma; in 3rd case because of significant enlargement and rigidity of liver left lobe, which didn't permit to create the space for manipulations in cardial portion of the stomach. The mean bed day turnover after traditional HGP with LB and after laparoscopic HGP was 12.2 and 5.4 respectively. Intraoperative complication was observed in one case--hemorrhage from lesser omentum's vessels. One complication was observed in immediate postoperative period, on the 6th day after traditional HGP: the eventration as a result of hard diarrhea due to antibacterial treatment was diagnosed. One more complication was observed in a year after traditional HGP: small stomach evacuatory function disorders as a result of its significant dilatation. These disorders occurred because of gastric mucosa inflammatory edema, decrease of anastomosis diameter and frequent vomiting due to aspirin taking. In this case the repeated operation--bandage's reposition was performed. There were no other complications. The rate of repeated operations was 4% which agrees with literature data.

Abstract
The results of 361 plastic operations in 296 patients with morbid obesity late after horizontal gastroplasty were analyzed. Plastic and corrective operations aimed at removal of redundant lipocutaneous "aprons" at the anterior abdominal wall, thighs, thoracic wall, gluteal region and the arms, represent a final stage of surgical treatment of patients with morbid obesity. The indications, technique and the results of plastic operations performed from 1985 to 1998, are thoroughly elucidated. The analysis of early postoperative complications has established, that it a reasonable to perform such operations 1-3 years after gastroplasty when body weight stabilizes and there are no vitamin deficiency, iron deficient anemia, hypoproteinemia, hydroionic disturbances or other complications of the later period. Complex prophylactic measures for prevention of pyoseptic and thromboembolic complications in patients with obesity late after gastroplasty permits to avoid severe complications and lethal outcomes in patients after plastic operations.

Abstract
The analysis of the first 14 operations of horizontal gastroplasty in patients with end-stage alimentary constitutional obesity was carried out, the operations being performed according to standard (9 patients) as well as laparoscopic method (5 patients). The mean body mass made up 133.6 kg, the mean height being 167.8 cm. Patients age was from 22 to 42 years. All the patients operated by laparoscopic method were women. Technique of laparoscopic horizontal gastroplasty is described, indications and contraindications to the operation are established. It is demonstrated, that laparoscopic gastroplasty, as well as previously performed 530 horizontal gastroplasties with the help of fluoric-lausan goffer band, performed in clinic since 1984, in present time is one of the most perspective method of surgical correction of obesity. The application of this method results in substantial and steady decrease of body mass of the operated patients with minimal risk of complications during surgical procedure as well as in postoperative period.

Abstract
The results of aspirative lipectomy in patients with 2nd and 3rd stage of alimentary-constitutional obesity are analysed. The effectiveness of lipectomy with surgical creation of a small ventricle and without previous surgery, has been demonstrated. The criteria of patients selection, based on their somatic and psychic features, are formulated. Aspirative lipectomy has certain advantages over other types of plastic surgery as it has the minimal rate of postoperative complications.
