Abstract Peritoneal adhesions are seen frequently after abdominal surgery and can cause serious complications. We aimed to evaluate the effects of the oral use of diclofenac sodium and ellagic acid on formation of postoperative adhesions in rats Studies have shown that agents with anti-inflammatory properties and antioxidant substances can prevent adhesion by decreasing oxidative stress. We compared and evaluated the effects of ellagic acid that has strong antioxidant and anti-inflammatory properties and the nonsteroidal anti-inflammatory diclofenac sodium on peritoneal adhesion development in our experimental study. Laparotomy was performed with a midline incision under general anesthesia and an adhesion model was created on the antimesenteric side of the cecum in Groups I, II, and III. Group I received 85 mg/kg ellagic acid and Group II, 50 mg/kg diclofenac sodium through the nasogastric catheter while Group III received no medication. Only laparotomy was performed in Group IV. The rats were sacrificed at the end of the 14th day. Following macroscopic scoring, tissue samples were removed and subjected to biochemical and histopathologic evaluation. The degree of adhesion and the malondialdehyde level were decreased (P < 0.05), and glutathione level increased (P < 0.05) in Group I compared to Group II and Group III. The effects of ellagic acid on the prevention of peritoneal adhesion were found to be stronger than diclofenac sodium. This can be explained by the fact that ellagic acid is a strong antioxidant and decreases oxidative stress with anti-inflammatory and anti-angiogenic effects.

Objective Although Achilles tendon ruptures can have many causes, they are known to develop most commonly with trauma. Nonsteroidal anti-inflammatory drugs (NSAID) and low doses of corticosteroids are used in the medical treatment of tendon ruptures. Ellagic acid (EA), which also has an anti-inflammatory effect, has been reported to show its effect via cyclooxygenase 2 (COX2) inhibition as well. The effects of EA and diclofenac sodium on tendon healing were compared in this study. Methods We used a total of 18 male New Zealand rabbits in 3 groups with 6 in each. The study was performed under general anesthesia with a xylazine-ketamine combination. After a defect was created in the right Achilles tendon of all the rabbits, group I was administered diclofenac sodium and group II was administered EA for 1 week, whereas the control group (group III) was not administered anything. Postoperative follow-up was provided for all groups. Results Euthanasia was performed in all subjects at the end of the eighth week, and the tendons were compared in terms of macroscopic and histopathologic features and tensile resistance. Although there was no statistically significant difference in the tensile resistance Newton values of group I and group II, these values were higher than in the control group, and the NSAI group values were statistically significantly higher than in the control group. Conclusions We concluded that EA and NSAIs could be effective in the recovery of tendon integrity and tensile strength and increasing the movement capacity in pathology caused by tendon damage because of their anti-inflammatory features.

BACKGROUND: Gamma glutamyltransferase (GGT) was reported recently to be associated with inflammation, oxidative stress and increased amino acid. However, role of GGT in insulin resistance pathomechanism is not exactly known. Therefore correlation of GGT with inflammation, oxidative stress and elevated amino acid, in men with central obesity need to be confirmed.METHODS: A cross-sectional study was designed. Men with central obesity were recruited and selected. Anthropometric parameters, creatinine, hs-CRP, fasting glucose, fasting insulin, glutathione peroxidase (GPx) activity, GGT, plasma total cysteine (tCys) and fatty liver were measured. Subjects were then divided in 4 groups based on waist circumference (WC) and fatty liver: Group I: WC ≤100 cm, without fatty liver; Group II: WC ≤100 cm, with fatty liver; Group III: WC >100 cm, without fatty liver; Group IV: WC >100 cm, with fatty liver. All biochemical characteristics in each group were then statistically analyzed.RESULTS: Seventy-two men with central obesity were selected. Numbers of subjects in each group were: Group I: n=33; Group II: n=5; Group III: n=17; Group IV: n=17. We found significant difference of HOMA-IR between Group I and IV, significant correlation between GGT and HOMAIR, and significant negative correlation between tCys with HOMA-IR in Group IV.CONCLUSION: GGT was significantly correlated with HOMA-IR in men with WC >100 cm and fatty liver. Further investigation with more subjects is necessary to determine clear GGT cut-off to distinguish subjects with fatty liver and insulin resistance.KEYWORDS: GGT, hs-CRP, GPx, tCys, HOMA-IR, insulin resistance

Purpose:  To evaluate the reliability of the visibility of the central incisor & the canine for the cervico incisal positioning of anterior maxillary teeth related to age & sex while the upper lip was in repose in dentate patients & the development of rehabilitation recommendations for edentulous individuals with regard to the location of the maxillary incisal edge Methodology: 308 subjects [152 Males & 156 Females] belonging to the age of 30 to 59 years were selected using a simple stratified random technique. There were three age and sex groups: Group I was 30 to 39 years old, Group II was 40 to 49 years old, and Group III was 50 to 59 years old. The vertical distances (in mm) between the lower border of the upper lip and the right maxillary central incisal edge and canine tip were measured and recorded using adhesive tape marked with millimetres. A single examiner recorded all the measurements and the values were tabulated and subjected to statistical analysis. Results: Men in Groups I and II had maxillary central incisor exposure ranging from +6 to -1mm, whereas males in Group III had exposure ranging from +5 to -2mm. There was an exposure range of +6 to -2 mm in females in Group I, +7 to -2 mm in Group II, and +5 to -2 mm in Group III for the central incisors. While the canine exposure in Group I and II and Group III ranged from +2 to -4mm in females, the exposure ranged from +3 to -3mm in men of all ages. In all groups, females had statistically significant (P0.05) more central incisor and canine exposure than men. Conclusions: The canine visibility was less variable in all the age groups and in both males and females in comparison to the central incisor. When restoring edentulous individuals, the average canine exposure dimension can be employed for cervico-incisal location of the anterior maxillary teeth.

Objective: To analyze, measure, compare, prove, and evaluate effectiveness of silodosin, diclofenac sodium, and the combination of both drugs in pain management after stent removal. Materials & Methods: Thirty-three patients were divided into three groups. Group I was given diclofenac Sodium 50 mg, group II was given silodosin 8 mg and group III was given the combination of diclofenac sodium 50 mg and silodosin 8 mg. The Wong Baker Pain Scale (WBPS) was assessed serially: two hours before the DJ stent removal, during DJ stent removal, and after the DJ stent removal (2 hours and 24 hours after). The data was analyzed by ANOVA and Kruskal-Wallis test. Results: In this study, 33 patients who underwent DJ stent removal were obtained. Wong Baker was presented in median (min-max) form. The WBPS study in each group did not differ statistically significant. Lowest WBPS during DJ stent removal was found in group III. Group III was better and statistically significant in reducing pain compared to group I and group II (p<0.05). WBPS two hours after removal in each group decreased and group III was better and statistically significant in reducing pain compared to group II, whereas group III compared to group I had an equivalent effectiveness. While the WBPS 24 hours after removal had the same value and did not differ significantly. No side effects or adverse events were found in the use of diclofenac sodium, silodosin, and their combinations. Conclusion: Single oral dose of diclofenac sodium combined with silodosin is effective to reduce pain after DJ stent removal.

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

Curcumin, a natural phenolic compound is an anti-tumor agent with anti-inflammatory and anti-oxidant properties. The aim of this research was to evaluate oxidative stress levels, the antioxidant activity and Curcumin concentrations by high performance liquid chromatography (HPLC) in an acute experimental inflammation induced by Turpentine oil (intramuscular 0.6 mg kg-1 body weight) and to compare a prophylactic versus a therapeutic regimen of Curcumin (oral suspension of 150 mg Curcumin kg-1 rat weight). Sixteen adult male Wistar rats were assigned to four groups: Control, Group I (Curcumin only), Group II (Curcumin administration, then induced inflammation after 1 hour) and Group III (induced inflammation then Curcumin administration after 2 hours). Oxidative stress was assessed by measuring serum malondialdehide and carbonylated proteins, while systemic and local total antioxidant capacity was determined by ABTS. Local tissue changes (muscle, kidney, liver) were analysed using histopathology. Results showed that acute inflammation significantly increased lipid peroxidation in Groups II and III compared to Control and Group I. A significantly reduced total antioxidant capacity (ATBS) was present in serum and kidney in Group II, also in muscle and kidney in Group III. ABTS levels were significantly increased only in the liver tissue of the animals in Groups II and III with induced inflammation as compared to Group I. This study proved the potential of Curcumin in reducing oxidative stress in both prophylactic and therapeutic regimens.

We have studied the effects of group I, II, and III metabotropic glutamate receptor (mGluR) agonists on rhythm generation by the gastric circuit of the stomatogastric ganglion (STG) of the Caribbean spiny lobster Panulirus argus. All mGluR agonists and some antagonists we tested in this study had clear and distinct effects on gastric rhythm generation when superfused over combined oscillating or blocked silent STG preparations. A consistent difference between group I agonists and group II and III agonists was that group I agonists acted excitatory. The group I-specific agonists l-quisqualic acid and ( S)-3,5-dihydroxyphenylglycine, as well as the nonspecific agonist (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid accelerated ongoing rhythms and could induce gastric rhythms in silent preparations. The group II agonist (2S,1′S,2′S)-2-(carboxycyclopropyl)glycine (L-CCG-I) and the group III agonist l(+)-2-amino-4-phosphonobutyric acid (l-AP4) slowed down or completely blocked ongoing gastric rhythms and were without detectable effect on silent preparations. The action of L-CCG-I was blocked partially by the group-II-specific antagonist, (RS)-1-amino-5-phosphonoindan-1-carboxylic acid [(RS)APICA], and the group-III-specific antagonist (RS)-α-methyl-4-phosphonophenylglycine completely blocked the action of l-AP4. Besides its antagonistic action, the group-II-specific antagonist (RS)APICA had a remarkably strong apparent inverse agonist action when applied alone on oscillating preparations. The action of all drugs was dose dependent and reversible, although recovery was not always complete. In our experiments, the effects of none of the mGluR-specific agonists were antagonized or amplified by the N-methyl-d-aspartate (NMDA)-receptor-specific antagonistd(−)-2-amino-5-phosphonopentanoic acid, excluding the contamination of responses to mGluR agonists by nonspecific cross-reactivity with NMDA receptors. Picrotoxin did not prevent the inhibitory action of L-CCG-I and l-AP4. We conclude that mGluRs, probably similar to those belonging to groups I, II, and III described in mammals, may play a role as modulators of gastric circuit rhythm generation in vivo.

Abstract: Aspirin is one of the non-steroid-anti-inflammatory drugs. Its pharmacodynamic effects are as an analgesic, antipyretic, anti-inflammatory, anti-thrombotic, and uricosuric agent. The side effects of aspirin are on the respiratory tract, the gastrointestinal tract, blood, metabolic processes, endocrine functions, pregnancy, hypersensitivity, and drug interaction. The purpose of this study was to evaluate the macroscopic and microscopic features of wistar rat stomachs after the administration of aspirin. This was an experimental study, using nine wistar rats divided into three groups equally. Group I, the control group, was given a food pellet only. Group II was given the pellet, added with aspirin 21 mg daily for 10 days. Group I and Group II were terminated on day 11. Group III was given the pellet, added with aspirin 21 mg/day for 10 days, and was terminated on day 14. All the wistar rat stomachs were examined macroscopically and microscopically. The results showed that the control group had a macroscopically normal stomach architecture, and the mucosa layers and rugae were intact and looked pinkish white. The groups treated with aspirin still showed normal stomach architecture, and the mucosa layers and rugae were intact but looked more palid than that of the control group. Microscopically, the stomach walls of the control group were normal, but groups treated with aspirin for 10 days revealed edema of the lamina propria, dilatation of capillaries; and predominantly neutrophilic infiltration in the lamina propria. Ceasing of aspirin administration showed a resolution of the inflammatory process, marked by diminished infiltration of PMN cells and tisuue edema. Conclusion: Aspirin treatment of 21 mg a day for 10 days revealed histopathologically acute gastritis of the wistar rat stomach walls. The inflammatory reaction was diminished after the cessation of aspirin.

Summary. Inflammation and pain can lead not only to a deterioration in the patient’s condition, but also to such local consequences as: bone resorption, loss of soft tissue volume, an increase in the wound healing time and patient rehabilitation in general. Inflammation-induced bone resorption in the area of implantation with direct prosthetics, caused by the activity of cytokines and prostaglandins, negatively affects the entire result of treatment of dentition defects in general. This is because the quality and quantity of bone tissue is one of the key points in the success of prosthetics on dental implants, therefore, pharmacological support of dental implantation and direct prosthetics is an important component of treatment. Purpose: to investigate the effect of inflammation and pain on peri-implant bone tissue at the stages of dental implantation and direct prosthetics and scientifically substantiate pharmacological support in order to prevent inflammatory bone resorption. Materials and methods. A clinical prospective study of 57 patients was carried out at the stage of dental implantation and direct prosthetics with randomization according to the type of pharmacological accompaniment: 1) group I received anti-inflammatory therapy in the form of a balanced inhibitor of COX-1, COX-2 and 5-LOG – nimesulide and analgesic therapy – dexketaprofen trometamol; 2) group II received anti-inflammatory therapy – a selective COX-2 inhibitor – meloxicam and analgesic therapy – ibuprofen; 3) group III did not receive anti-inflammatory and analgesic therapy due to contraindications to the use of non-steroidal anti-inflammatory drugs. Patients of groups I, II, III underwent: clinical, radiological and functional research methods by monitoring the state in dynamics. Results. According to the data obtained, the indices of pain intensity in group I were significantly lower (p < 0.05) as of 1 and 2-d days, compared with groups II and III. The stabilization of inflammatory processes in group I was recorded on the 2-d day. There was a significant decrease (p < 0.05) in the signs of the inflammatory process in patients of group I on the 3rd day (3.01±0.11 units), and on the 7-th day – their complete absence (1.12±0.23 units). In group II, significant regression of inflammation was noted on the 4th day (3.14±0.12 units), and on the 7-th day, minimal signs were observed (2.04±0.17 units). A decrease in signs of inflammation in group III occurred from the 5th day (3.31±0.28 units), and inflammatory phenomena were observed on the 7th day of the study (2.65±0.27 units). In group I, there was a significant stop in the loss of stability of the connection between the bone tissue and the dental implant on the 20-th day (65.08±1.03 points). As of the 25-th day, in patients of group I of the study, there was significantly higher (p < 0.05) indicators of the coefficient of stability of the implant (66.21±1.40 points) in relation to group II of patients (62.93±0.94 points), in who used selective COX-2 inhibitors, and group III (62.90±0.75 points), where NSAID’s were not used. The loss of marginal bone around the dental implant during the study period in group I was 0.5±0.23 mm CI, in group II – 1.1±0.34 mm, in group III – 1.3±0.28 mm. Side effects in group I of the study were recorded in 5.3 % of patients taking drugs nimesulide and dexketoprofen, and in 15.8 % of those in group II who took drugs meloxicam and ibuprofen. Conclusions. Complex pharmacological support of dental implantation and direct prosthetics on implants in the treatment of dentition defects, consisting of perioperative analgesia – dexketoprofen trometamol, as well as nimesulide for anti-inflammatory therapy, made it possible to influence the trauma-induced bone resorption in the implantation area by controlling inflammation. As a result, on the 20-th day in the patients of the group I of the study, a significant stop was noted in the loss of stability of the connection of the bone tissue and the dental implant (65.08±1.03 units), and on the 25-th day of the study in the group I it was found significantly higher (p < 0.05) indicators of the coefficient of stability of the implant and less loss of height of marginal bone tissue in relation to groups II and III of patients. This pharmacological complex made it possible to achieve stabilization of pathological processes in soft tissues – stopping the formation of edema on the 2-d day, a significant decrease (p < 0.05) of signs of the inflammatory process on the 3-d day (3.01±0.11 points) and to implement effective pain prevention at the stages of dental implantation and direct prosthetics.
