Abstract The haemato-biochemical indices and oxidative stress markers in horses naturally infected with Trypanosoma evansi were evaluated by analyzing the level of these parameters between T. evansi infected (microscopically positive patent group and PCR positive latent group) and infection free horses. To compare the hemato-biochemical indices and oxidative stress indicators, horses were divided into three categories based on diagnostic test employed and positive results obtained. These included Romanowsky stained slide positive group (Group I; n = 6), PCR positive group (group II; n = 28) and negative control group (group III, n = 30), revealing parasitologically positive patent, molecular positive latent and disease free status of horses. A significant reductions in total erythrocytes count (TEC, P = 0.01), haemoglobin (Hb, P = 0.01) and packed cell volume (PCV, P = 0.04) was noticed both in group I and group II while significant neutrophilia and lymphocytopenia was observed in group I when compared to negative control group. Substantial increase in creatinine (CRTN, P = 0.032) and gamma glutamyl transferase (GGT, P = 0.012) in group I while significant decrease in glucose (GLU, P = 0.04) and iron (Fe, P = 0.01) were noticed in both group I and group II in comparison to group III. A significant difference in lipid peroxides (LPO, P = 0.01) with highest level in patent group I (15.33 ± 0.53) followed by PCR positive latent group (14.09 ± 1.66) indicates higher lipid peroxidation in erythrocytes and oxidative stress in decreasing order when compared with infection free control horses (9.83 ± 0.97). Catalase (CAT, P = 0.01) was significantly lower in parasitological (0.82 ± 0.14) and molecular positive cases (1.27 ± 0.35) in comparison to control group (3.43 ± 0.96). The levels of superoxide dismutase (SOD, P = 0.01), reduced glutathione (GSH, P = 0.01) and ferric reducing antioxidant power (FRAP, P = 0.01) were significantly lower in parasito-molecular positive cases as compared to infection free control horses. An inverse correlation of RBC count with LPO and GSH and a direct correlation with catalase, SOD and FRAP was revealed. Overall, the observed substantial decreases in the oxidative parameters like catalase CAT, SOD, GSH and FRAP activities with remarkably elevated levels of LPO indicate high exposure of erythrocytes to oxidative damage in T.evansi infected horses.

  The niacin in energy drinks has metabolic product that cause oxidative stress and liver damage, while the liver damage can be prevented by hepatoprotective agents. Scoparone in Artemisia vulgaris L. can act as a hepatoprotector by its antioxidant effect. This study aimed to investigate the effectivity of Artemisia vulgaris L. extract as a hepatoprotector in wistar hepatocytes induced by niacin. This study used 25 male rats which were divided into 5 groups: normal, the negative control, the positive control, the treatment group I, and II. Treatment was conducted for 28 days. The samples were terminated and the hepatocyte were prepared for histological examination. Histological appearance was catagorized as mild, moderate, and severe damage with or without inflamatory cells activity. The data analysis by Kruskal Wallis showed significant difference (p<0,001). Further analysis by Mann Whitney revealed significantly difference (p<0,05) between normal group and all groups, negative control group and positive control group, and positive control group and treatment group I, but not significantly difference between negative control group and treatment group I, negative control group and treatment group II, positive control group and treatment group II, and between treatment groups. The study concluded that the effectivity of Artemisia vulgaris L. extract has not been proven as a hepatoprotector but further study is needed to draw a definite conclusion.   Keywords: energy drink, niacin, Artemisia vulgaris L., hepatoprotector

Abstract Introduction The aim of obturation in the root canal is to completely seal the canal space to eliminate all the portals of entry and exit between root canal and periodontal space. Various techniques have been developed to achieve a hermetic seal. Materials and Methods As many as 150 extracted human maxillary central incisors were taken for the study. Biomechanical preparation was done up to F5 protaper file. According to different obturation techniques, samples were divided into six groups, keeping 30 samples in experimental and 15 samples in control groups. Group I–Lateral Condensation, Group II–Thermafil, Group III–Beefill, Group IV–GuttaFlow, Group V–Positive Control group, Group VI–Negative Control group. After obturation, the samples were immersed in 2% Rhodamine-B dye for 24 hours. Each sample was longitudinally sectioned to examine under confocal laser scanning microscope. Statistical Analysis The results were evaluated with ANOVA and posthoc Tukey honest significant difference (HSD) comparison test. Results The mean values of dye penetration of different groups were Group I (Lateral Condensation) 1.51 ± 0.451, Group II (Thermafil) 0.918 ± 0.399, Group III (Beefill) 1.30 ± 0.559. Group IV (GuttaFlow) 0.655 ± 0.396, Group V (Positive Control group) 1.96 ±0.046, Group VI (Negative Control group) 0 ± 0. The lowest mean value of apical microleakage was found in GuttaFlow amongst all experimental groups. Conclusion It can be concluded that the GuttaFlow obturating material exhibited better apical sealing ability with canal walls.

Abstract At any moment, the continuous usage of medications can accompanied by DNA damage and the accumulation of such damages can cause serious consequences. Antidepressants are long-term used drugs and the incidence of their genotoxic impacts cannot be excluded. Therefore, this work was designed to investigate the possible genotoxic effects of the commonly used antidepressants (fluoxetine and amitriptyline) in adult male rats. Detection of DNA damage in individual cells was assessed by comet and micronucleus assays in three different cell populations i.e. liver, testis and bone marrow tissues of 24 swiss albino adult male rats. The animals were randomly allocated into three groups of 8 rats each: Group I - rats orally-administered distilled water via gavage tube for four weeks as a negative control. Group II - rats orally-treated with fluoxetine hydrochloride solution (7.2mg/kg/day) via gavage tube for four weeks. Group III - rats orally-treated with amitriptyline hydrochloride solution (27mg/kg/day) via gavage tube for four weeks. The results showed that both drugs (Group II and Group III) induced the same extent of DNA damage, as evidenced by a significantly higher DNA fragmentation in liver and testis tissues with increased frequencies of micronuclei formation in bone marrow tissues as compared with the negative control (Group I). These findings indicates that both Fluoxetine and Amitriptyline have genotoxic potentials and can induce the same extent of cytogenetic damage in rats. Special precautions and medical supervision should be taken in consideration with their uses.

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.

The previous study reported that Etlingera elatior (Wualae) has activity as immunostimulant with dose at 300 mg/kg BW and 400 mg/kg BW. Formulating natural product into effervescent granule (GE) can increase practicality and interest to consume traditional medicine. This study aims to investigate the immunostimulant activity of Wualae ethanolic extract in the effervescent granule. Wualae was macerated with ethanol then formulated into effervescent granule at dose 300 mg/kgBW and 400 mg/kgBW. Formulations were evaluated. Animals were divided into 4 groups and treated with: group I (positive control); group II (negative control); group III (GE dose at 300mg/kgBW); and group IV (GE at dose 400mg/kgBW) for 7 days and at days 8, groups were infected by Staphylococcus aureus intraperitoneally. Immunostimulant activity was measured by calculating the Specific Phagocytic Activity (SPA) of macrophage. Data collected from the evaluation and measurement of the SPA then analyzed using SPSS. Results from the evaluation were considered good except the moisture content of effervescent granule. Results from SPA was found that effervescent granule at dose 300 mg/kgBW and at dose 400 mg/kgBW have 26.33% and 32.5% consecutively with significance 0.02 (p<0.05). Thus, effervescent granule has comparable phagocytosis activity with positive control.

ABSTRACTObjective: Studies about the dispersion of hydroxyl ions through dentin of endodontically retreated teeth are scarce. The present study aims at examining the diffusion of calcium hydroxide in vitro by recording the pH changes of retreated root canal using two types of calcium hydroxide preparations. Materials and Methods: A total of 45 recently extracted single-rooted mandibular first premolars were collected and cleaned from calculus and remains of periodontal tissue. The teeth so collected were stored in thymol 10% solution till use. During collection, teeth with cracks, open apices, and restorations were excluded. Root canal preparations were performed using Protaper rotary system files, till #F3 file. All canals were obturated using cold lateral condensation and zinc oxide-based sealer. After 7 days, all gutta-percha were removed and the canals were irrigated with normal saline. The teeth were then randomly distributed into three groups. Canals in Group I were kept empty without any dressing to serve as a negative control group, Canals in Group II were filled with a freshly prepared mixture of calcium hydroxide powder with normal saline solution, and Group III was filled with Metapex. Periodically, the calcium hydroxide material was removed and the pH was measured using pH meter at 7, 10, 14, and 30 days. Results: The pH values of Group II and III ranged between 9.2 and 11.2. This was found to be highly significant against the negative control group. After 7 and 10 days, freshly mixed Ca(OH)2 showed the higher pH than the creamy Metapex, and statistically the difference was highly significant after 10 days (P<0.001). After 14 days, Metapex group pH was higher than freshly mixed Ca(OH)2, but it was not statistically significant as they reached nearly the same pH after 30 days (P>0.05). Conclusion: All Ca(OH)2 preparations had high pH around the roots after 7 and 10 days. Metapex continued to have higher pH after 14 days.
