Abstract. Introduction. The problem of providing effective care to patients with burn injuries remains far from being finally solved. Due to significant immune disorders that occur against the background of thermal damage, the use of immunomodulatory drugs remains promising. Therefore, the aim of this study was to analyze the effectiveness of systemic use of the immunomodulatory drug Liastenum® in the complex treatment of patients with burn injuries. Materials and methods: The study involved 35 patients with burn injuries with the index of damage severity ranging from 30 to 60 units. Patients in the main group (n = 15) in addition to the usual treatment received an immunomodulator Liastenum®, which was administered intramuscularly at a dose of 2 mg once every 3 days (course dose — 10 mg). Treatment of patients in the comparison group (n = 20) did not involve the use of drugs with targeted immunocorrective action. Examination of patients included laboratory immunological examination of venous blood with assessment of various parts of the immune system and determination of the “Neutrophilic granulocytes form factor” indicator, which was performed on the 3rd, 14th, 21st day after the injury. The results of the study and their discussion. The obtained results allowed to confirm the ability of Liastenum® to stimulate the functional activity of neutrophilic granulocytes, restoring the phagocytic reserves of these cells, to normalize the level of lymphocytes and their individual subpopulation forms. In general, the action of the immunomodulatory drug was characterized by a balanced effect on the cellular, humoral parts of the immune system, phagocytosis. Conclusions. The effectiveness of systemic use of immunomodulatory drug Liastenum® in a comprehensive program of care for patients with burn injuries by balanced correction of immune disorders was laboratory established.

The influence of trauma on parameters of humoral immunity changes has been studied. The study includes 52 patients with various forms of traumatic illness, aged 18-69 years (37,91±4,28). The control group consisted of 16 patients who had undergone a routine surgery not related to the pathology of musculoskeletal system. All patients of the main group were divided into 3 groups according to the severity of their condition. Analysis of parameters of cellular link of immune system was performed by defining the pool of B-lymphocytes (CD22+ lymphocytes), determination of main classes' immunoglobulins, and calculation of integrated indicators. The highest expression (immune disorders of II-III grades) of changes of cellular immunity was observed in patients with severe traumatic illness (detailed clinical picture). Surgical intervention, even without traumatic injury significantly affect cellular immunity, but in patients with traumatic illness immunity disorders were significantly higher than in the comparison groups.

Summary Aim: Determination of the range of regional blood flow and fluoride influx during normal incorporation of revascularized fibula grafts used for mandibular reconstruction. Evaluation, if healing complications are preceded by typical deviations of these parameters from the normal range. Assessment of the potential influence of using “scaled population-derived” instead of “individually measured” input functions in quantitative analysis. Methods: Dynamic F-l 8-PET images and arterialized venous blood samples were obtained in 11 patients early and late after surgery. Based on kinetic modeling regional blood flow (K1) and fluoride influx (Kmlf) were determined. Results: In uncomplicated cases, early postoperative graft K1 - but not Kmlf -exceeded that of vertebrae as reference region. Kmn values obtained in graft necrosis (n = 2) were below the ranges of values observed in uncomplicated healing (0.01 13-0.0745 ml/min/ml) as well as that of the reference region (0.0154-0.0748). Knf values in mobile non-union were in the lower range - and those in rigid non-union in the upper range of values obtained in stable union (0.021 1-0.0694). If scaled population-derived instead of measured input functions were used for quantification, mean deviations of 23 ± 17% in K1 and 12 ± 16% in Kmlf were observed. Conclusions: Normal healing of predominantly cortical bone transplants is characterized by relatively low osteoblastic activity together with increased perfusion. It may be anticipated that transplant necrosis can be identified by showing markedly reduced F− influx. In case that measured input functions are not available, quantification with scaled population-derived input functions is appropriate if expected differences in quantitative parameters exceed 70%.

ABSTRACT Various techniques for sensitising erythrocytes and latex particles with gonadotrophins, particularly with HCG, are described. The haemagglutination inhibition reactions are generally interpreted by means of »erythrocyte settling patterns«. By a new method of evaluating these patterns a relatively precise quantitative determination is possible. Latex agglutination inhibition reactions on slides are particularly suitable as rapid qualitative tests. In cases where the maximum attainable sensitivity of the agglutination inhibition tests is insufficient, e. g. for determining LH concentrations in urine, the hormone in the test fluid has to be concentrated or extracted. An alternative method is a modified haemagglutination inhibition test for large volumes which is applicable to unconcentrated urine. Due to non-specific inhibitions the above-mentioned tests cannot be applied to unprocessed serum. Agglutination inhibition tests with HCG are already well advanced, pregnancy diagnosis being their main application. Now that highly purified HCG is available, a satisfactory specificity for these tests can be attained. If the immune system for HCG is used for estimating LH, it has to meet additional specificity requirements. Furthermore, the measure of cross-reaction and the choice of standard merit special attention. Finally, a literature survey is given of test systems in which LH and FSH were used as antigens.

The Impact

Abstract Introduction Skeletal muscle is a major site for whole-body glucose disposal, and determination of skeletal muscle glucose uptake is an important metabolic measurement, particularly in research focussed on interventions that impact muscle insulin sensitivity. Calculating arterial-venous difference in blood glucose can be used as an indirect measure for assessing glucose uptake. However, the possibility of multiple tissues contributing to the composition of venous blood, and the differential in glucose uptake kinetics between tissue types, suggests that sampling from different vein sites could influence the estimation of glucose uptake. This study aimed to determine the impact of venous cannula position on calculated forearm glucose uptake following an oral glucose challenge in resting and post-exercise states. Materials and Methods In 9 young, lean, males, the impact of sampling blood from two antecubital vein positions; the perforating vein (‘perforating’ visit) and, at the bifurcation of superficial and perforating veins (‘bifurcation’ visit), was assessed. Brachial artery blood flow and arterialised-venous and venous blood glucose concentrations were measured in 3 physiological states; resting-fasted, resting-fed, and fed following intermittent forearm muscle contraction (fed-exercise). Results Following glucose ingestion, forearm glucose uptake area under the curve was greater for the ‘perforating’ than for the ‘bifurcation’ visit in the resting-fed (5.92±1.56 vs. 3.69±1.35 mmol/60 min, P<0.01) and fed-exercise (17.38±7.73 vs. 11.40±7.31 mmol/75 min, P<0.05) states. Discussion Antecubital vein cannula position impacts calculated postprandial forearm glucose uptake. These findings have implications for longitudinal intervention studies where serial determination of forearm glucose uptake is required.

Relevance. The study of the etiological structure, clinical features of congenital infections and the immune status of children with perinatal HIV contact will help to improve the program for the diagnosis, treatment and prevention of these diseases.Objective. To characterize the clinical features of congenital infections and changes in the immune system in children with perinatal HIV contact, taking into account their HIV status.Methods. A clinical, serological, molecular genetic, cytological, immunological examination of 203 children with perinatal HIV contact, including 91 HIV-positive patients and 112 HIV-negative patients.Results. Congenital infections were diagnosed in 43.3% of children with perinatal HIV contact. They were characterized by a predominance of cytomegalovirus (30%) and Chlamydia trachomatis (14.3%) in the etiological structure; those infections proceeded as a mono-infection (61.4%) or in a localized form (52.5%). In the group of HIV-positive children, congenital infections developed in 68.1% of patients. In most cases congenital infections were caused by cytomegalovirus (45.1%), herpes simplex virus (6.6%) and bacteria (11%); they proceeded as an associated infection (46.8%), and in a clinically manifest localized (61.3%) and generalized forms (33.9%). The clinical features of congenital infections in HIV-infected children were associated with more significant disorders in the immune system, especially in T-cell link.Conclusion. The revealed clinical and immunological features of congenital infections in children with perinatal HIV contact must be considered during diagnostic, therapeutic and preventive procedures.
