ANALYSIS OF THE EFFICIENCY OF COMPLEX TREATMENT OF PATIENTS WITH GENERALIZED PERIODONTITIS ACCORDING TO THE CHANGES IN THE ACTIVITY OF BLOOD SERUM ENZYMES

Introduction. The mechanisms of generalized periodontitis (GP) development and methods of its treatment remain obscure, so it is important to study changes in the activity of enzymes responsible for maintaining homeostasis, as well as the inclusion of medicines that regulate them into the complex treatment. Aim of research is to study the influence of comprehensive treatment in patients with GP on the dynamics of the activity of indicator blood serum enzymes in different observation periods. Methods. There were examined 29 people with a healthy periodontium and 143 patients with GP aged 19-45 years, somatically healthy, before, immediately after the treatment, after 6 and 12 months. Patients were divided into subgroups with chronic (A) and acute (B) course: IA and IB – the initial degree; IIA and IIB – the I degree; IIIA and IIIB – the II degree. The activity of lactate-dehydrogenase (LDG), arginase and sorbitol dehydrogenase (SDG) in blood serum has been studied. In addition to the basic periodontal therapy, the microalgal medicine Spirulina platensis was prescribed endogenously, and the paste with the same amount of spirulina powder and enterosorbent and 0.05% chlorhexidine bigluconate solution was exogenously prescribed. Results. In patients with IA and IB subgroups, LDG activity has increased in 1.37- and 1.48-times (p1 <0.01; p1 = 0.001). Under the influence of treatment, it has decreased in all patients, especially after 6 months – in 1.33- and 1.50-times (p2<0.001), but after 12 months it has been increased more (p2> 0.05; p2 <0.05). Arginase activity in IA and IB subgroups has reduced in 1.23- and 1.31-times (p1<0.05; p1=0.005). Due to the therapy, it has increased immediately, after 6 and 12 months, respectively in 1.23- and 1.26-times; in 1.21- and 1.25-times, and in 1.20-1.23-times (p2<0.05; p2> 0.05; p1> 0.05). In subgroups IA and IB, SDG activity has increased in 1.15- and 1.17-times (p1> 0.05), and after the treatment it has decreased immediately in 1.14- and 1.16-times (p2 <0.05); later it increased, but differed slightly from the norm (p1> 0.05). LDG activity in subgroups IIA and IIB has increased in 1.38- and 1.54-times (p1 <0.01; p1=0.001). After the treatment in subgroup IIA, it has decreased in 1.21-times immediately and after 6 months (p2<0.005), and a year later it has increased (p2>0.05; p1>0.05); in subgroup IIB it has decreased in 1.33-, 1.39- and 1.24-times (p2<0.05; p2<0.01; p2 <0.05 and p1> 0.05). In subgroups IIA and IIB, arginase activity has reduced in 1.32-times (p1=0.001). Immediately after the treatment in subgroup IIA, it has increased in 1.21-times (p2=0.005), and subsequently decreased (p2> 0.05). In the IIB subgroup, its increasing was 1.31-, 1.27- and 1.25-times (p2 <0.05), and the difference with the norm was insignificant. SDG activity in subgroups IIA and IIB has increased in 1.18- and 1.24-times (p1 <0.05; p1=0.01). After the treatment, it has decreased at all terms in both subgroups similarly: 1.13- and 1.16-times; 1.17- and 1.17-times; 1.12- and 1.10-times (p2 <0.05; p2 <0.05; p2> 0.05) and it differed slightly from normal one. The largest increase in LDG activity was found in subgroups IIIA and IIIB – 1.45- and 1.62-times (p1≤0.001). As a result of therapy immediately, after 6 and 12 months it has decreased in 1.18- and 1.20-times; 1.26- and 1.23-times; 1.13- and 1.15-times (p2 <0.05; p2 <0.05; p2> 0.05; p1> 0.05). In subgroups IIIA and IIIB, arginase activity has reduced in 1.32- and 1.37-times (p1≤0.005). Treatment has increased the indices in group IIIA in 1.22-, 1.22- and 1.18-times (p2<0.05), and in group IIIB it immediately increased in 1.25-times and then decreased (p2 <0.05; p2> 0.05). The activity of SDG in IIIA and IIIB subgroups has increased in 1.31-times (p1=0.001). Under the influence of therapy in subgroup IIIA, it has decreased immediately, after 6 and 12 months in 1.17-, 1.22- and 1.13-times (p2 <0.05; p1> 0.05), and in subgroup IIIB it initially decreased, but after a year it has increased (p2>0.05) and the difference with healthy people became significant. The altered indices of activity of enzymes studied in patients with GP did not exceed the reference values, but showed a violation of the enzyme system, which was regulated by the treatment. Prior to therapy, reliable (p<0.05-0.005) strong correlations were found between these parameters: LDG with SDG (r> 0.71) and arginase with SDG (r> -0.90). After the treatment, they were not found, six months later one correlation has restored, and a year later – both have restored, which indicates the necessity for the maintenance of endogenous therapy after six months. Conclusion. GP is accompanied by significant (p1<0.05-0.001) changes in the enzymes activity in the blood: in LDG and SDG, it is increased, and in arginase – it is reduced. Comprehensive treatment has regulated these disorders, especially immediately and after 6 months (p2<0.05-0.001). The activity of LDG and SDG of the initial and the I degree immediately and after 6 months and arginase at the initial degree after 6 and 12 months became the closest to norm. In the GP of the II degree, the data of healthy people were not achieved, but the difference with them was insignificant (p1> 0.05).

STUDY OF THE ACTIVITY OF SOME RAT SERUM ENZYMES IN THE DYNAMICS OF EXTRAHEPATIC CHOLESTASIS

Extrahepatic cholestasis occurs with mechanical obstruction of the main extrahepatic or main intrahepatic ducts. The most common cause of extrahepatic cholestasis is common bile duct stones. This article describes hypertension in the bile ducts and acholysis developing in cholestasis, which cause serious functional and morphological changes in the liver and lead to the rapid growth of liver insufficiency. Thus, in the dynamics of extrahepatic cholestasis development there are significant shifts in blood serum of experimental animals, manifested by hyperfermentemia. These changes indicate the involvement of the liver in the pathological process, which naturally requires their correction.

Correlation of Oxidative Stress and Hepatoprivial Syndrome in Dogs with Comorbidity of Babesiosis and Dirofilariasis

The comorbidity of babesiosis and dirofilariasis in dogs is an important clinical problem, despite the significant achievements of recent years in understanding the pathogenesis of this mixed invasion. It has been established that the leading pathogenetic component in the development of the cytolytic syndrome with this comorbidity in dogs is oxidative stress resulting from the mismatch of the prooxidant and antioxidant resources of the cell under the influence of Babesia canis parasitism. On the basis of morphological, biochemical and ultrasonographic studies, a direct correlation was found between oxidative stress and hepatoprivial syndrome in dogs with comorbidity of babesiosis and dirofilariasis. Hepatoprivial syndrome was accompanied by the development of hypochromic anaemia, leukocytosis, hyperproteinemia, hypoglycemia, a disorder of pigment metabolism and an increase in the catalytic activity of serum enzymes, which indicated a violation of the metabolic activity of the liver and damage to its parenchyma. The activation of lipid peroxidation processes in the hepatocytes contributed to an increase in the catalytic activity of the blood serum enzymes in sick animals, and to a decrease in the antioxidant defence of sick dogs, due to a relative decrease in the level of vitamin A in the blood. Thus, the comorbidity of babesiosis and dirofilariasis in dogs enhances the oxidative syndrome that underlies the pathogenetic mechanisms of this mixed invasion, thereby increasing the degree of involvement in the pathological process of the liver, which is manifested by hepatoprivial syndrome.

Effect of N- 3, 4-Dichlorophenyl -N, N-Dimethylurea (Diuron) Herbicide to Serum Biochemistry of Clarias gariepinus

Assessing the effect of Diuron herbicide on post juvenile African catfish (Clarias gariepinus) using specific biochemical markers could provide vital information concerning the health status with regards to electrolyte determination. The fishes were subjected to different concentrations of diuron of (0.5, 0.75, 1.0, 1.25, and 1.5mgL-1 respectively) for 96hrs and the alterations in the serum enzymes, metabolites and ion level were determined. The lethal concentration (LC50) value of the herbicide was 1.0mg L-1 for 96h of exposure. During the experiment different behavioural changes were observed and recorded and blood samples were collected after 96hours of experiment to check for the effect of fish exposed to different concentration of diuron herbicide and the parameters observed were serum enzymes (ALT, ALP, AST and LDH). Biochemical examination was also carried out to know the changes in Total protein, glucose and cortisol level. Ion level examination was carried out to assess changes in sodium (Na+), potassium (K+) and chloride (Cl-). It was observed that there were significant differences (P˂0.05) in the serum enzymes analysis, biochemical examination and ion level examination and these parameters revealed differences with varying concentrations of diuron herbicide. Thus, diuron possesses toxicity effects on C. gariepinus Keywords: Herbicide, Clarias gariepinus, serum enzymes

Effects of concurrent eight-week aerobic trainings and Rosa canina L. fruit hydroalcoholic extract on liver enzymes and malondialdehyde of liver in male rats following an acute aerobic exercise until exhaustion

Background: Rosa canina L. has high levels of carotenoids, flavonoids and, vitamin C antioxidant compounds that can withstand the destructive effects of exhaustive exercise-induced oxidative stress. The present study aims to investigate the effects of concurrent eight-week aerobic training and Rosa canina L. fruit hydroalcoholic extract on some liver enzymes and malondialdehyde of liver in male rats following an acute aerobic exercise until exhaustion. Methods: The present research was an experimental study. Forty male Wistar rats were randomly divided into four groups (N=10): placebo (without exercise + distilled water 2 ml supplement), supplement (without exercise + Rosa canina L extract, 100 mg/kg), exercise (8 weeks exercise + distilled water 2 ml), combined (8 weeks exercise + Rosa canina L extract, 100 mg/kg). At the end of the experiment, half of the rats were killed immediately before exhaustive exercise; while the other half were killed immediately after performing an acute exhaustive exercise on the treadmill. Serum enzymes AST, ALT, and hepatic malondialdehyde levels were measured by ELISA and thiobarbituric acid methods, respectively. Results: The results show that in all groups except the combined group serum AST, ALT, and malondialdehyde of the liver were significantly increased following an acute exhaustive exercise compared to the prior exhaustive exercise (P<0.05). Conclusion: The use of Rosa canina L Fruit hydroalcoholic extract with aerobic exercise prevented the increase of hepatic malondialdehyde and serum enzymes AST, ALT levels following an acute exhausting exercise.

In vivo evaluation of inorganic nanoparticle complexes against CCL4 induced hepatotoxicity

Background: Combination of different chemotherapy drugs and nanoparticles as a carrier have shown promising delivery system in cancer treatment. Doxorubicin is considered as a potent anticancer drug. However, it’s off target activities and possible side effects, make its use limited. Recently, in the field of nanomedicine, different nanoconjugates have been developed as a unique platform for the delivery of therapeutic drugs. Objective: The aim of present study was to evaluate the best possible combination for efficient delivery of DOX with combination of gold, silver and zinc oxide nanoparticles to target site against carbon tetrachloride induced rat hepatotoxicity. Methodology: Effect of different conjugates administrated for 14 consecutive days was evaluated. Results: In comparison to DOX, Au:DOX, ZnoO:DOX and Ag:DOX showed less sign of liver fibrosis as evaluated by serum enzymes and histo-pathological analysis. However, among all the conjugates, Ag: DOX conjugate showed most significant results. The serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase values were (111.2 ± 38.21, 323.2 ± 46.88 and 303.6 ± 73.80 respectively) very close to control group (72.2 ± 19.41, 368 ± 59.78 and 259.4 ± 61.54 respectively). Conclusion: Our results demonstrated that Ag: DOX may exhibit hepato-protective activity against CCl4 induced liver damage.

Evaluation of Crossbreeding Parameters for Immunocompetence and Serum Enzyme Profile in a Partial Diallel Cross Involving Three Genetic Groups of Chicken

Background: Poultry production in rural India is mostly a non-intensive venture comprising native chicken with low production potential but higher disease resistance and adaptability. Present study is attempted for developing a suitable cross for rural poultry production as well as identifying the genetic groups that are nicking well through a partial diallel cross. Methods: A partial diallel cross using three genetic groups/ breeds of chicken viz. coloured synthetic male line (CSML), Local native chicken (Desi) and CARI-Red as the parent lines was designed. CSML was used as male and CR as female line only. The progenies were evaluated for crossbreeding parameters viz. combining abilities and heterosis for immune response and serum enzyme profile to identify the best combining parent lines.Result: Significantly higher (P less than 0.05) cell-mediated (CMI) and humoral immune response (HIR) and immune organ (spleen, bursa of fabricius and thymus) weights were recorded in CR purebred followed by Desi purebred, while CSML purebred exhibited lowest immunity. Variances for SCA differed significantly (P less than 0.001) for HIR and immune organ weights. Inconsistent but significantly higher (P less than 0.01) serum enzymes (AST, ALT and ALP) and AST/ALT ratio were recorded in triple cross and D x CR. Variances for SCA differed significantly (P less than 0.05) for serum enzymes. Results revealed that the CARI-Red and Desi were the improver parent lines for better immunocompetence and serum enzyme profile, respectively in the crosses.

Clinical-biochemical status of hens due to changes of battery cages height location

In the conditions of industrial poultry farming, the body of hens is constantly exposed to numerous technological stressors, the least studied of which are long-term ones, that can provoke chronic stress. One such technological stressor is an increase in the level of cage equipment, which is used by producers to obtain a larger amount of products from 1 m2 of poultry area. The aim of this work was to study the physiological state of the hen’s body based on the clinical biochemical analysis of their blood serum, depending on the battery cages height. In the conditions of a modern complex for the production of edible eggs in a poultry house with an area of 2 915 m2, 4 groups of hens were formed, each of them was kept on a separate floor-analogue in terms of area and cage equipment. Each floor was equipped with «Big Dutchman» 3-tier battery cages. Battery cages of each floor were separated from each other by a lattice floor so that cages of 1–3 tiers entered up to the 1st floor, 4–6 tiers – up to the 2nd, 7–9 tiers – up to the 3rd, and 10–12 tiers – up to 4th floor of cage equipment. Biochemical parameters and activity of hens blood serum enzymes were determined on a BioChem FC-360 biochemical analyzer. For this, 30 blood samples with a volume of 1.0–1.5 ml were taken from axillary veins of laying hens in each group at the age of 18 weeks (at the beginning of the study) and at 52 weeks. It was found that increasing the layering of cage equipment does not have a negative impact on the hen’s body. So, for keeping hens in cages of multi-tier battery cages located on floors 2–4 (4–12 tiers), the biochemical status and activity of their blood serum enzymes were within the physiological norm. Whereas, for hens kept in battery cages of the a multi-tiered system on the 1st floor there was an increase in glucose levels of 60.5–71.0%, creatinine – by 9.7–12.3%, phosphorus – 82.6–100.0%, was observed a decrease in calcium to phosphorus ratio 46.7–50.0%, which was confirmed by an increase in the activity of alkaline phosphatase by 22.3–27.0%, as well as an increase in the activity of aspartate aminotransferase by 3.2–13.8%, lactate dehydrogenase - by 48.5–65.1% and gamma-glutamyl transferase – by 16.4–20.6%. It has been proven that the main consequences of chronic stress caused by keeping hens in the lower floor cells of the multi-tiered battery cage are reflected in the biochemical parameters of their serum, namely increased glucose, creatinine, enzyme activity and violation of calcium to phosphorus ratio.

Activity of hydrolytic enzymes of innate immunity in bacterial and coronaviral pneumonia.

The aim of this work was to study the enzymatic activities of hydrolases in the blood serum of patients with bacterial pneumonia, pneumonia caused by SARS-CoV-2 and practically healthy volunteers who made up the comparison group. A number of blood serum enzymes related to innate immunity were determined: lysozyme, elastase, BAPNAamidase and deoxyribonuclease activity. Results: it was shown that blood serum in pneumonia caused by SARS-CoV-2 has the highest level of elastase and lysozyme activities, which significantly (p<0,001) exceeded the corresponding activities of sera amongst patients with bacterial pneumonia and in the comparison group. It was also found that trypsin-like activity of blood serum was increased in bacterial pneumonia in comparison with pneumonia caused by SARS-CoV-2 (p <0,001). There were no statistically significant differences in the level of deoxyribonuclease activity of blood serum among analyzed groups.
