    The research aim was to study the dynamics of biogenic amines in the brain, tumor and intact skin of urokinase (uPA) gene knockout mice on day 21 of the B16/F10 melanoma growth.Material and methods. The study included male and female uPA gene knockout (-uPA, n = 38) and wild type mice (+uPA, n = 61). Melanoma was transplanted subcutaneously. Levels of biogenic amines were studied by ELISA in tissues obtained on day 21 of carcinogenesis.Results and discussion. Intact (-uPA) mice showed an increased total content of biogenic amines: in the skin - due to noradrenaline increase by 4.8 times in males and by 4.9 times in females, histamine - by 3.6 times in males and by 1.6 times (p < 0.05) in females, serotonin - by 3.4 times in males and by 8.3 times in females; in the brain - due to noradrenaline increase by 3.5 times in males and by 3.2 times in females, dopamine by 2.1 times in males and by 2.9 times in females, while histamine content decreased. Melanoma development in (-uPA) mice was characterized by: lower levels of adrenaline with high NA concentrations and an increase in the serotonin metabolism in the brain; higher histamine concentrations in the tumor and higher serotonin levels in the skin; similar to (+uPA) mice levels of adrenaline (males) and noradrenaline in the tumor and higher levels of adrenaline in the tumor and histamine in the skin in (-uPA) females.Conclusions. The uPA gene knockout limits the development of stress at the central regulatory level due to lower levels of A together with increasing serotoninergic mediation in the brain, as well as modulates the immune antitumor response due to higher levels of histamine in the tumor and 5 serotonin in the skin, as a result of lower monoamine oxidase activity, in mice with B16/F10 melanoma

    The structure and mechanical properties of polymer films obtained from natural latex and filled by clay suspensions were investigated. It was shown that surface modification of the clay particles by alkylbenzyldimethylammonium chloride decrease film properties. Mixing of latex with untreated bentonite lead to the inorganic layers reagregation and dehydratation at the drying stage but supports high mechanical properties due to parallel orientation of the clay particles.Π˜Π·ΡƒΡ‡Π΅Π½Π° структура ΠΈ Ρ„ΠΈΠ·ΠΈΠΊΠΎ-мСханичСскиС свойства ΠΏΠΎΠ»ΠΈΠΌΠ΅Ρ€Π½Ρ‹Ρ… ΠΏΠ»Π΅Π½ΠΎΠΊ Π½Π° основС Π½Π°Ρ‚ΡƒΡ€Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΊΠ°ΡƒΡ‡ΡƒΠΊΠ° «РСвултСкс», Π½Π°ΠΏΠΎΠ»Π½Π΅Π½Π½Ρ‹Ρ… слоистыми силикатами Π½Π° стадии латСкса.

    The state of antioxidant system (the activity of catalase and ceruloplasmine), the intensity of chemiluminescence, and oxidative modification of proteins were studied in blood plasma of 61 patients with ovarian cancer (cystadenocarcinoma) III–IV stage in state of remission and ones with a local recurrent tumor. The dynamics of these indices was analyzed in dependence of recurrent tumor vascularization. The statistically significant changes of the activity of some links of antioxidant system were found, as well as chemiluminescence intensity increase in blood plasma. The level of oxidative modificated protein molecules was raised, the most expressed for products of the main character (530 nm). The dynamics of level of carbonyl derivatives of the neutral and main character (370 and 530 nm) was opposite directed during intensification of recurrent tumour vascularization and increase in speed of blood-groove in a recurrent tumorΠ£ 61 больной Ρ€Π°ΠΊΠΎΠΌ яичников (цистадСнокарцинома) III–IV стадий Π² состоянии рСмиссии ΠΈ с Π»ΠΎΠΊΠ°Π»ΡŒΠ½Ρ‹ΠΌ Ρ€Π΅Ρ†ΠΈΠ΄ΠΈΠ²ΠΎΠΌ ис- слСдованы Π² ΠΏΠ»Π°Π·ΠΌΠ΅ ΠΊΡ€ΠΎΠ²ΠΈ ΠΈΠ½Ρ‚Π΅Π½ΡΠΈΠ²Π½ΠΎΡΡ‚ΡŒ Ρ…Π΅ΠΌΠΈΠ»ΡŽΠΌΠΈΠ½Π΅ΡΡ†Π΅Π½Ρ†ΠΈΠΈ, состояниС ряда звСньСв антиоксидантной систСмы (Π°ΠΊΡ‚ΠΈΠ²Π½ΠΎΡΡ‚ΡŒ ΠΊΠ°Ρ‚Π°Π»Π°Π·Ρ‹, Ρ†Π΅Ρ€ΡƒΠ»ΠΎΠΏΠ»Π°Π·ΠΌΠΈΠ½Π°) ΠΈ ΡƒΡ€ΠΎΠ²Π΅Π½ΡŒ ΠΎΠΊΠΈΡΠ»ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠΉ ΠΌΠΎΠ΄ΠΈΡ„ΠΈΠΊΠ°Ρ†ΠΈΠΈ Π±Π΅Π»ΠΊΠΎΠ² общСпринятыми спСктрофотомСтричСскими ΠΌΠ΅Ρ‚ΠΎΠ΄Π°ΠΌΠΈ.

    The purpose of the study was to reveal special features of the Π’16/F10 melanoma growth in urokinase (uPA) geneΒ knockout mice with and without chronic neurogenic pain (CNP). Material and methods. The study included male andΒ female Π‘57Π’L/6 mice (n = 102) and C57BL/6-Plautm1.1BugThisPlauGFDhu/GFDhu mice with uPA gene knockoutΒ  (n = 48). Mice of the main subgroups underwent subcutaneous transplantation of Π’16/F10 melanoma 2 weeks afterΒ bilateral ligation of sciatic nerves (CNP model); mice of the same strain with standard melanoma transplantation servedΒ as controls. Results and discussion. Survival of uPA gene knockout mice did not differ from that of normal animals – 1.5 times higher in females than in males (p < 0.05), with melanoma onset in gene-deficient mice a week earlier. TheΒ dynamics of tumor growth had pronounced gender differences: in females, the tumor did not grow and its maximalΒ volume prior to death was 1.0 cm3, while tumors in males were characterized by an active growth with two peaks ofΒ volume increase (weeks 2 and 4). Melanoma was weakly metastatic – solitary metastases to the lungs (in females) orΒ no metastases, but pulmonary and heart hemorrhages were noted (in males). CNP decreased the survival of uPA geneΒ knockout females, as well as of normal animals, but did not influence the survival of males; primary tumors in genedeficientΒ mice appeared a few days later than in controls but their growth was more intense, with diminished genderΒ differences. Increased metastasis was manifested by the initiation of metastatic lesions to the lungs and liver in males,Β with maintained pulmonary hemorrhages, and by increased number of metastatic foci in the lungs together with theΒ appearance of pulmonary hemorrhages in females. Conclusions. The influence of uPA gene knockout on the courseΒ of Π’16/F10 melanoma differs in male and female mice. CNP enhances malignant tumor growth, diminishing genderΒ differences, and activates melanoma metastasis

    Aim. To study the levels of reduced and oxidized glutathione (GSH and GSSG, respectively), as well as the thiolΒ status in gastric cancer (GC) tumors of various histological types and grades.Materials and methods. The indicators were determined by ELISA methods in tumor, peritumoral and visuallyΒ intact tissues obtained during surgery from 52 patients with GC: 18 patients had a G1-2 adenocarcinoma (AC), 8Β with G3 AC, 6 with signet ring cell cancer (SRCC), 14 with combined gastric lesions (CGL) – AC with signet ringΒ cell fragments, 6 with patients with a component of undifferentiated cancer, G4.Results. In the groups of patients with low-differentiated and undifferentiated tumors, the GSH content in the tumorΒ tissue and the peritumoral zone was higher than in the group of patients with well- and moderately-differentiatedΒ tumors. Tumor GSH levels in G3 AC and SRCC exceeded the values in visually intact tissues. Moreover, in theΒ visually intact tissue of patients with SRCC, GSH level was reduced relative to G1-2 AC and CGL. GSH in allΒ tissues of patients with CGL was higher than in patients with G1-2 AC. The lowest level of GSSG in the tumorΒ tissue was registered in SRCC: 27.5% lower than in G1-2 AC and 30.3% lower than in G3 AC. Patients withΒ undifferentiated tumors (G4 AC) had the highest GSH content in all studied tissues: by 29.9% in tumor; by 40.7%Β in peritumoral zone; and in visually intact tissue not only GSH, but also GSSG was increased by 22.5–25.5% inΒ comparison with AC G1-2. G4 AC was also characterized by a sharp increase in the thiol status in tumor tissuesΒ by 80.2 and 89.9% higher than in visually intact and peritumoral tissues, and it was statistically higher than in ACΒ G1-2, AC G3, SRCC and CGL. The ratio of GSH and GSSG was the most informative.Conclusion. Poor AC differentiation (in the row G1-2, G3, G4) and a change of histological tumor type (AC, SPLΒ and SRCC), i.e. an increase in tumor aggressiveness, were accompanied by the enhancement of reductive processesΒ in tumor tissue, as evidenced by the statistically significant increase in the GSH/GSSG coefficient and a sharpΒ increase in the thiol status in G4 AC.ЦСль.

    Local synthesis and metabolism of sex hormones allow the skin to regulate autonomously both nociceptive reactions and proliferative processes in various pathologies. The purpose of the study was to reveal theΒ influence of chronic neurogenic pain on the balance of sex hormones in the skin, tumor and perifocal area inΒ male mice in the dynamics of Π’16/F10 melanoma growth. Material and methods. The study included Π‘57Π’L/6Β male mice. Animals were divided into the main group – animals with Π’16/F10 melanoma transplanted afterΒ the development of chronic neurogenic pain (n=25), comparison group (n=27) – animals with standard tumorΒ transplantation, controls – males with chronic neurogenic pain (n=8), and intact mice (n=8). Levels of estradiolΒ (E2), estrone (E1), testosterone (T), progesterone (P4) (CUSABIO, China), estrogen receptors – ERΞ±, ERΞ²Β (Π‘loud-Clone Corp. USA, China), progesterone (RP4) and androgens (RA) (CUSABIO, China) were determined in 10 % homogenates of skin, tumor and perifocal tissues 1, 2 and 3 weeks after Π’16/F10 melanomaΒ transplantation using standard ELISA test systems adapted for experimental animals. Results. Chronic neurogenic pain causes an imbalance of sex steroids with marked hyperestrogenism. The imbalance is achievedΒ by increased content of estradiol and receptors of estrogen, increased concentration of progesterone withΒ inhibition of its receptor apparatus, as well as reduced levels of testosterone with increased concentration ofΒ androgen receptors. Melanoma in animals with chronic neurogenic pain grows and develops in a target organΒ with an altered steroid balance, which leads to changes in the tumor characteristics. Chronic neurogenic painΒ and B16/F10 melanoma has a unidirectional effect on the local hormonal status of the skin.Π›ΠΎΠΊΠ°Π»ΡŒΠ½Ρ‹ΠΉ синтСз ΠΈ ΠΌΠ΅Ρ‚Π°Π±ΠΎΠ»ΠΈΠ·ΠΌ ΠΏΠΎΠ»ΠΎΠ²Ρ‹Ρ… Π³ΠΎΡ€ΠΌΠΎΠ½ΠΎΠ² ΠΏΠΎΠ·Π²ΠΎΠ»ΡΡŽΡ‚ ΠΊΠΎΠΆΠ΅ ΠΎΡΡƒΡ‰Π΅ΡΡ‚Π²Π»ΡΡ‚ΡŒ Π°Π²Ρ‚ΠΎΠ½ΠΎΠΌΠ½ΡƒΡŽ Ρ€Π΅Π³ΡƒΠ»ΡΡ†ΠΈΡŽ ΠΊΠ°ΠΊ Π½ΠΎΡ†ΠΈΡ†Π΅ΠΏΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ€Π΅Π°ΠΊΡ†ΠΈΠΉ, Ρ‚Π°ΠΊ ΠΈ ΠΏΡ€ΠΎΠ»ΠΈΡ„Π΅Ρ€Π°Ρ‚ΠΈΠ²Π½Ρ‹Ρ… процСссов ΠΏΡ€ΠΈ Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… патологичСских состояниях.

    Introduction. Cytochrome C in mitochondria transfers electrons from complex III to complex IV, and it is a signaling molecule in the apoptosis realization.The objective was to evaluate the level of cytochrome C in cell mitochondria in various organs of female mice with standard and stimulated growth of experimental B16/F10 melanoma.Methods and materials. The experiment was performed on female C57BL/6 mice (n=168). The groups were: intact animals (n=21); controls with a model of chronic neurogenic pain (CNP) (n = 21); group M β€” standard B16/F10 melanoma transplantation (n=63), group CNP + M β€” B16/F10 melanoma transplantation 3 weeks after CNP model creation (n=63). The level of cytochrome C (ng / mg protein) were measured by ELISA (Bioscience, Austria). Statistical analysis of results was performed using the Β«Statistica 10.0Β» program.Results. After 1 week of standard melanoma growth, an increase in the level of cytochrome C by 2.7 and 1.7 times was detected in mitochondria of the brain and liver; by the 3rd week, it decreased in the liver and skin by 1.7 times. In melanoma mitochondria, the level of cytochrome C was lower than in the skin of intact animals: by 2.5 times after week 1, by 4.5 times after week 2, and by 4.6 times after week 3. After 1 week of stimulated melanoma growth, the level of cytochrome C decreased compared control values: by 2.2 times in the brain, by 1.9 times in the liver, by 1.4 times in the skin; by week 3, it decreased by 4.8 times in mitochondria of the brain, by 4.7 times β€” in the liver, by 2.3 times β€” in the heart, by 1.9 times β€” in the skin. In melanoma mitochondria, the level of cytochrome C was lower than in the skin of intact animals: by 15.3 times after week 1, by 10.3 times after week 2, and by 8.8 times after week 3.Conclusion. Low level of cytochrome C were found in melanoma mitochondria in standard and stimulated tumor growth. The data can be used in the experiment and in clinic for using exogenous cytochrome C as an agent slowing down the malignant process.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.
