Malachite green (MG) dye, besides coloring is used as an effective aquaculture therapeutic. The present study assesses the mitigating ability of Emblica officinalis (EO) fruit extract against the dye induced chronic (60 days) cyto-toxicity in Cyprinus carpio. For this, four experimental groups were maintained: group I—control, group II—MG, group III—EO (positive control), group IV—MG + EO. The study was made at three tiers: detailing structural anomalies using a light microscope and transmission electron microscope (TEM), biochemical estimation of antioxidant enzymes, and lipid peroxidation and molecular analysis of expression patterns of HSP70, and CYP1A genes. MG intoxication resulted in necrosis, cytoplasmic vacuolation, glycogen depletion, abundant macrophages, loss of cell integrity and prominent nuclear alterations. Significant (p < 0.05) inhibition in the activities of catalase (CAT), superoxide dismutase (SOD), glutathione-S-transferase (GST) and reduced glutathione (GSH), along with an elevation in malondialdehyde (MDA) levels, occurred after 60 days of MG exposure. CYP1A and HSP70 genes presented a significant change in their expression in MG treated fish. Whereas oral supplementation with EO significantly restored the histo-architecture, normalized the altered enzymatic activity, reduced the oxidative stress level and regulated the expression of HSP70 and CYP1A genes. Thus, it can be concluded that EO acted as an effective ameliorant against malachite green induced cyto-toxicity in Cyprinus carpio.

  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.

In the present study the cardioprotective effects of curcumin, a herbal polyphenolic compound, against sodium fluoride (NaF)-induced toxicity in rat heart was evaluated. Fifty rats were divided into five experimental groups containing 10 rats each. Group I received standard water and diet and was used as a normal group; groups II and III were pretreated with curcumin intraperitoneally for 7 days prior to NaF intoxication. Group IV was pretreated with vitamin C, a standard antioxidant, intraperitoneally for 7 days prior to NaF intoxication and used as a positive control group. The animals in group V were intoxicated with NaF for the same time and used as a control group. There was a significant increase in lipid peroxidation along with a decrease in superoxide dismutase activity in the homogenates of tissues of the NaF-treated animals. Curcumin pretreatment in animals prior to fluoride intoxication normalized the levels of biochemical parameters measured.

Multidrug-resistant tuberculosis (MDR-TB) is a tuberculosis infection that is resistant to the treatment at least two of the most powerful anti-tuberculosis drugs, such as Isoniazid and Rifampisin. Increased cases of MDR-TB in morbidity and mortality become obstacles in the control of tuberculosis (TB), thus requiring supportive treatment of natural ingredients that can contribute in the treatment of TB, such a noni fruit. The main objective of this study was extract of noni fruits to inhibition the growth of strain MDR-TB bacteria, and compered it with the anti-TB drugs. The Morinda c. Linn (Noni) fruits was extraced by ethanol (96%). The extract was filtered through whatman No.1 filter paper, evaporated to dryness on a water bath until the solvent evaporated completely and yield of the crude extract. The experiment were divided into 3 groups, i.e.: negative control: group I; positive control: group II; crude extracts noni fruit: group III: combinations of crude extracts noni fruit and anti-TB drugs (K, AK, and OF). Each group was divided into three groups’ doses of 30 mg/ml, 40 mg/ml and 50 mg/ml. The Anti-tuberculosis activities of extracts noni fruit and K, AK, and OF against TB-MDR bacteria were tested by susceptibility test using proportion method in Lowenstein-Jensen (LJ) media.The anti-tubercular activity of noni fruits was determined by the minimum inhibitory concentration (MIC) of the bacterial growth at various doses 30 mg/ml, 40 mg/ml, and 50 mg/ml. The research design used post-test only contol group, and analyzed using analysis of variance and post hoct test. The extracted of Morinda c.Linn (noni) fruits have antitubercular activity to inhibiton of growth MDR-TB bacteria at various doses (p value=0,000). At a dose 30 mg/mlthe mean rate of the growth colonies of MDR TB-bacteria whit the mean rate 59,00 ± 27,81, and at a dose 40 mg/ml was1,50 ± 2,81. While at a dose of 50 mg/ml the bacterial colonies of MDR-TB did not grow in media. The combination of Morinda c.Linn (noni) fruit with anti-tuberculosis drugs, was the smallest groups to inhibit and eliminate MDR-TB bacteria at a dose 30 mg/ml(0,00 ± 00.00). The experimental results confirmed the extracted of Morinda c.Linn (noni) fruits have antitubercular activity as well as anti-TB drugs, and the combination of the extracted of Morinda c.Linn (noni) fruits and anti-TB drugs was the best groups to inhibiton of growth MDR-TB bacteria.   Keywords: TB-MDR Bacteria, Morinda c.

There has been little information and much confusion regarding the genotoxic effects of fluoride. The purpose of this study was to examine the spermatogenic influence of sodium fluoride (NaF) on the germ cells by means of the mouse sperm morphology test. Male mice of genotype B6C3F1 were obtained at about eight weeks of age and maintained on a low-fluoride diet (<0.2 ppm F) and distilled water ad libitum throughout the experiment. At approximately 13 weeks of age, the animals were randomly assigned to eight groups. Group I was intubated with the Maximum Tolerable Dosage (MTD) of NaF (70 mg/kg). Groups II through VI received NaF by stomach intubation at doses of 35, 20, 10, 1, and 0.1 mg/kg, respectively. Group VII served as a negative control and was intubated with distilled water. The positive control, Group VIII, was exposed to a known mutagen, cyclophosphamide (20 mglkg, i.p). The animals were treated daily for five days, and killed by cervical dislocation 35 days after the first exposure to chemicals. Slides of sperm from the cauda epididymides were prepared and blindly scored for morphological abnormalities. Weight of the testes was recorded, and the femurs were saved for fluoride (F) analysis. Analysis of bone F demonstrated the effective absorption of fluoride following intubation. The counts of abnormal sperm and the weights of the testes for mice exposed to NaF doses up to the MTD were not significantly different from those of the negative control. The results of this study showed that NaF did not have adverse effects on mouse sperm morphology.

Objectives: Hepatotoxicity is the most complicated side effect of isoniazid (inh)in the patient treated for tuberculosis. In causes 8–30% hepatotoxicity in the developing world.Metabolism of INH produces a metabolite, called acetyl isoniazid. In this study hepatoprotectiveeffect of honey, in isoniazid induced animal model was assessed. Study Design: Randomizedcontrol trial. Setting: Saidu Medical College, Saidu Sharif Swat, KP. Period: October ToDecember 2017. Material and Methods: 40 healthy male rabbits were assigned randomly tothe group i, ii, iii and iv by using lottery method. Ten animals were grouped each row. Theisoniazid-induced hepatotoxic model was created by giving 50 mg inh/kg orally on daily basisfor eleven days. Group i was taken as negative control group ii as a positive control. Group iii andiv were experimental groups treated with 50 mg /kg/day and 100 mg /kg/day buckwheat honeyrespectively for eleven days. SPSS Version 16 software was used, mean, s.d. were determinedin all the groups. Values of serum bilirubin, sgpt, and alkaline phosphatase were comparedwith each other using pairt-test. Results: SGPT, Serum bilirubin, and alkaline phosphatasewere obtained in all the animals. Comparing group 1 negative control with group 2, 3 and 4shows statistical significance, (p=0.00). Comparing group 2 positive control with 3 and 4 showsstatistical significance, (p=0.00). Further comparing group 3 with group 4 also shows statisticalsignificance (p=0.00). Conclusion: From the above finding, it has been revealed that honeyhas got a protective effect in regressing hepatitis that has been induced in rabbit’s model byhigh doses of isoniazid. Related studies performed in which different chemicals and drugs havebeen tried for their protective role in isoniazid induced hepatitis also shows a similar type ofresults.
