The efficacy of antiplatelet therapy with acetylsalicylic acid (aspirin) and the frequency of cardiovascular events development in patients with arterial hypertension
Abstract. It has been shown, that the decrease of indices of aggregation of leukocytic-thrombocytic suspension in the presence of adrenaline according to optical aggregatometry by 50% and more (in 7-8 days of aspirin intake) in comparison with the initial level is associated with reliable reduction in the number of cardiovascular events during 1,4±0,8 y. that allows to consider the given criterion as aspirin resistance. The conclusion is made that the frequency of resistance to ASA revealed by the end of early postcrisis period in patients with arterial hypertension makes up 67%. The quantity of emergency calls and hospitalizations due to diseases of the cardiovascular system is reliably larger in patients suffering from arterial hypertension with revealed on the basis of optical aggregatometry data resistance to aspirin during 1,4±0,8 year.

Subclinical atherosclerosis in patients with rheumatoid and reactive arthritis
Abstract. 75 patients with rheumatoid arthritis (RA), 41 patients with reactive arthritis and 28 healthy subjects without clinical manifestations of atherosclerosis or any risk factors of its development were studied. All patients underwent ultrasonic investigation of the arterial vessels with the reactive hyperemia test, measurement of the intima-media thickness (IMT) of carotids and sizing up of the total area of atherosclerotic plaques lesion. It has been determined, that RA is accompanied by functional and organic atherosclerotic changes of arterial vessels. These signs of atherosclerosis in RA positively correlate with the patient’s age, duration of the disease, Ritchie index, C-reactive protein level, proatherogenic changes in lipid profile. In patients with RA atherosclerotic plaques were detected. The total area of atherosclerotic plaques lesion is associated with rheumatoid factor and C-reactive protein level. The reliable sings of ReA atherogenesis induction were not revealed. Arterial vessels changes registered in this group reliably did not differ from those found in the control group of healthy persons.
Clinicolaboratory characteristics of gastroduodenal pathology in adolescents of pre-conscription and military age
Abstract. 239 adolescents of pre-conscription and military age (16-27 years) were examined: 74 – with functional dyspepsia syndrome, 52 – with erosive-ulcerous pathology of the stomach and duodenum, 113 – the control group. Macrotrophic and microtrophic somatotypes in adolescents of pre-conscription and military age are factors increasing the feasibility of gastroduodenal pathology development (р<0,05) and associated (rs>0,3; р<0,05) with the estimation of pain syndrome and immunity parameters. Gastroduodenal pathology influence effects (р<0,05) on the reduction of cellular immunity characteristics and the increase of humoral immunity characteristics were revealed. The content of blood serum transforming growth factor b1 (TGF- b1) in adolescents of pre-conscription and military age is higher (р<0,05) in gastroduodenal pathology and is associated (r>0,3; р<0,05) with the intensity of clinical manifestations, isolated cardiac connective tissue defects, trophology status, proatherogenic changes of blood lipids, adaptation body mechanisms tension, determined by hormonal and psychovegetative status indices and suppression of cellular immunity.
The dependence of IL-1a and TNF-a content on the activity of the pituitary-adrenal system in patients with low vegetative reactivity in the preoperative period and their correction
Abstract. The content of IL-1a, TNF-a, and the activity of the pituitary-adrenal system (PAS) in the preoperative period in patients with low vegetative reactivity and their correction with diazepam were analyzed.
29 patients hospitalized for planned operation and 17 persons of the control group were examined. The vegetative status was evaluated by means of vegetative indices, the level of ACTH and cortisol was determined by RIA method, the content of cytokines was determined by enzymoimmunoassay. It has been established, that in the preoperative period in patients with the prevalence of parasympathetic activity and low vegetative reactivity when PAS activity is practically not changed the indices of IL-1adecrease and those of TNF- increase. Diazepam administration during two days of the preoperative period to such patients reduces parasympathetic influence and PAS activity, raises vegetative reactivity that contributes to increase of the content of IL-1a and decrease of TNF-a . Thus, diazepam administration to patients with the prevalence of parasympathetic activity and low vegetative reactivity during two days of the preoperative period reduces PAS activity, promoting IL-1a synthesis.

The influence of perinatal damage of the central nervous system in newborns on the level of proteins of acute phase of inflammation
Abstract. Dynamics of the level of proteins of acute phase of inflammation in newborn children with perinatal damages of the CNS was investigated. It has been found that such children have a tendency towards growth of concentration of the investigated proteins in the blue blood in comparison with the funic one. The average correlation relationships between the levels of С3 and С4 complement components, ferritin and LDG, МВ – fractions of CPK and LDG have been established. The weak interrelation has been established between С3 complement component and a1 - acidic glycoprotein, С3 complement component and LDG, С4 complement component and a1 - acidic glycoprotein, CPK and its МВ – fraction, CPK and GGT. It has been determined that the presence of perinatal damage of the nervous system in a newborn child does not influence an average level of proteins of acute phase of inflammation, however, the level of С3 complement component, a1-acidic glycoprotein, CPK and GGT in newborns with perinatal damage of the CNS is reliably lower, than in children without any pathology of the nervous system. And on the contrary, the levels of С4 complement component, МВ – fractions of CPK, ferritin and LDG in them are reliably higher in comparison with children of the control subgroup.

Therapeutic effectiveness of sodium dalteparine in patients with torpid generalized common psoriasis
Abstract. Therapeutic effectiveness of low molecular heparin – sodium dalteparine aganist the background of traditional treatment was studied in 33 patients with torpid generalized common psoriasis: 18 persons had often recurrent course of the disease (PASI 25,1±0,5) and 15 – persistent recurrent one (PASI 37,3±0,8).
During 8-10 days sodium dalteparine (2500 IU /d) was injected subcutaneously into the abdominal field. The mean duration of patients staying in the hospital was 19,5±0,2 days. After treatment PASI score less than 8 was determined in patients with often recurrent course of psoriasis and in persons (18-30 years) from general group with torpid course that correlated with the significant improvement of skin psoriatic process (PASI -75).
The administration of sodium dalteparine contributes to the reduction of prothrombin potential of blood plasma in patients with often recurrent course of psoriasis that correlated with the marked clinical effect in this group of patients. No significant effect of sodium dalteparine on the number of thrombocytes, coagulation time of capillary blood was found. Hemorrhagic complications were also not observed in these patients.
In 6 months stable remission after the treatment was preserved in 72,2% of patients with often recurrent psoriasis. During 4-6 months relative remission was noted in 53,2% of persons with persistent recurrent course of the disease.

The peculiarities of hemostasis disorders in widespread psoriasis vulgaris with different course
Abstract. The disorders of hemostasis in widespread psoriasis vulgaris are a matter of discussion in medical literature. It remains unclear in which clinical form of generalized psoriasis the changes in hemostasis are most vividly manifested.
The character of hemostasis changes is thought to depend on clinical peculiarities of psoriasis vulgaris course. The most striking changes in hemostasis are revealed in patients with frequently relapsing forms of the disease. In patients with constantly relapsing psoriasis such changes are expressed to a lesser extent than in those with frequently relapsing disease. The hemostasis changes in patients with frequently relapsing disease are manifested mainly by lower levels of the protein С and by the increased concentrations of fibrinogen in the blood serum. This fact testifies to the important role of increasing coagulation potential in the pathogenesis of psoriasis, especially in case of relapsing disease, which requires hemostatic correction by drugs or medical methods reducing the prothrombogenic potential in patients’ blood.

The reaction of hypophysial – thyroid system to sensibilization of host organism with Ascarides somatic proteins
Abstract. The state of the histological structure, morphometric indices of the thyroid gland as well as the levels of thyrotropic hormone, triiodothyronine and thyroxin in the blood serum of Wistar line rats, sensitized with somatic proteins from the skin-muscular sac of adult Ascarides were studied.
It has been established that sensibilization of host organism with Ascarides somatic proteins causes changes of thyroid gland histological structure and its morphometric indices which are characterized by the enlargement of follicles, accumulation of colloid substance in them, reduction of follicular epithelium height and the size of its nuclei. These changes point to suppression of thyroid gland activity that is proved by the decreased levels of hypophysis thyrotropic hormone, triiodothyronine and thyroxin in the blood serum.

Zymozan activated autoserum in the treatment of the primary form of bacterial keratitis
Abstract. The aim of this study was to evaluate the efficacy of zymozan activated autoserum application in complex treatment of the primary form of bacterial keratitis.
The research was conducted on 36 patients with the primary form of bacterial keratitis. The 1st group included 22 patients (traditional treatment), the 2nd group consisted of 14 patients (traditional treatment + autoserum activated by zymozan (АSАZ)). The efficacy of treatment was evaluated with the help of impression cytology of the cornea.
The application of ASAZ in complex treatment of the primary form of bacterial keratitis promoted the development of the early beginning (Ме=2,5; р=0,041) and duration reduction of ulcerous-inflammatory defect epithelization by 3,5 days (р=0,002).
Zymozan activated autoserum application is an effective means to activate phagocytosis, proliferative and reparative processes during bacterial keratitis primary form treatment.
Application of zymozan activated autoserum in the treatment of experimental bacterial keratitis
Abstract. The aim of this study was to evaluate the efficacy of zymozan activated autoserum application in complex treatment of bacterial keratitis.
The experimental research was carried out on 102 rabbits. Bacterial keratitis was caused by intralamellar trepanation of the cornea and its subsequent contamination. The animals were divided into five groups: the 1st group – the first day after the damage and contamination of the cornea, the 2nd group – without treatment; the 3rd group – antibacterial treatment; the 4th group – zymozan activated autoserum treatment; the 5th group – the combined treatment (antibacterial treatment and that with zymozan activated autoserum).
Cytologic and histologic researches of the cornea were carried out on the 1st, 3rd, 7th, 14th and 30th days of observation. Statistical processing of the obtained data was performed using the program «STATISTICA 6.0».
It was determined that the application of zymozan activated autoserum resulted in positive dynamics of the clinical course of the disease. Its usage promoted clarification of the ulcerous-inflammatory zone due to phagocytosis enhancement as a result of the increase in the number of macrophages, activation of proliferative and reparative processes.
Zymozan activated autoserum application in complex treatment of bacterial keratitis is expedient for the purpose of decrease of the inflammatory reaction and activation of reparative processes in the cornea.
Transillumination diagnosing of dystrophic changes in the anterior section of the eye
Abstract. The aim of the study was to assess the diagnostic value of a simplified, inexpensive transillumination (TI) technique as a method to visualize CB glaucomatous changes.
The prospective study involved 57 (105 eyes) patients with the confirmed glaucoma diagnosis. In a darkened clinic room, the transilluminator was placed on the temporal part of the upper eyelid and then moved with the eyelid far behind the globe. The TI effects and CB were studied through the translucent sclera.
In the glaucoma group, TI revealed depigmentation of CB. Characteristic TI defects and narrowing of the plicata band were found in 50% of eyes with mild glaucomatous damage, in 71% with moderate damage and in 85% with severe damage. Tonography revealed correlation of decrease of aqueous humor production with CB changes.
TI indicated the actual condition of CB mass and iris depigmentation. CB visualization can be used as an effective and simple diagnostic method to reveal additional information about glaucomatous damage.

The influence of exogenous phenol compounds on the processes of morphogenesis in callus culture of the lilac (syringa vulgaris l.)
Absract. The influence of exogenous phenol compounds (PhC) and their precursors on the content of PhC and realization of the morphogenetic potential in the lilac callus culture of the flower origin has been studied. During the investigation it has been found that when callus is cultured on the media in the presence of exogenous phenol compounds and their precursors on the 20th day of cultivation the content of the amount of phenol compounds in callus culture of the lilac is 6-10 times higher in comparison with the control medium. The most effective medium for the induction of morphogenetic processes turned out to be the medium containing 6,1 mg/l of rutin + 1,65 mg/l of phenylalanine (medium 5). Inclusion of exogenous phenol compounds in the cultivation medium helps to reduce the time of growing callus to maximize accumulation of phenol compounds three times.
