Immunosuppressant and steroid therapy for SLE have not shown satisfactory results. Another method of therapy that is being developed is vaccines and escalating dose immunotherapy using self-antigen. The aim of this study was to assess the balance of immune cells through the ratio of pro-inflammatory and anti-inflammatory cells and cytokines in SLE using self-antigen dsDNA therapy. Methods: Female Balb/c mice 6-8 weeks old separated randomly to negative control group and pristane induced lupus (PIL) mice group. PIL mice groups were injected pristane intraperitoneally. Twelve weeks after the injection, the mice were evaluated for clinical and serological manifestations (anti-dsDNA levels). Mice with lupus signs were divided into four groups; positive control group: PIL mice without EDI dsDNA therapy, treatment A: PIL mice with EDI dsDNA therapy dose I (0.01μg/ml, 0.1μg/ml, 1μg/ml), treatment B: PIL mice with EDI dsDNA therapy dose II (0.1μg/ml, 1μg/ml, 10μg/ml), and treatment C: PIL mice with EDI dsDNA therapy dose III (1μg/ml, 10μg/ml, 100μg/ml). dsDNA were injected once a week and the dose was increased every week. Samples were analyzed for active/inactive dendritic cells ratio, Th1/Th2 cells ratio, Th17/Treg cells ratio and IL-17/TGF-β levels ratio. Results: Escalating dose antigen specific therapy with dsDNA injection of third dose reduced active/inactive dendritic cells ratio (p=0.000), Th1/Th2 cells ratio (p=0.010), Th17/Treg ratio (p=0.004) and decrease IL-17/TGF- β levels ratio (p=0.004) significantly compared to positive control. Conclusion: Escalating dose antigen specific therapy with dsDNA injection of dose III was able to regulate balance ratio of inflammatory cells and cytokines in PIL mice thus the immune tolerance may improve compared to control groups.

Spirulinasp.is an alga that has antioxidant and anti-inflammatory potential.Phycocyanin contained in Spirulina platensis can reduce tumor necrosis factor-? levels, neutrophils, and M2 macrophages in inflammation. This research aims to investigate the anti-inflammatory activity of S. platensisin a mice wound model. Thirty-two male Wistar rats were incised and divided into 4 groups. The first therapeutic group (X1) received S. platensisextract at a dose of 500 mg/kgBW/day, and the second therapeutic group received S. platensisextract at a dose of 750 mg/kgBW/day. The negative control group (C1) received a saline solution and the positive control group (C2) received diclofenac sodium 20mg/kgBW/day. Serum TNF-? levels examined by the Enzyme-Linked Immunosorbent Assaymethod. Neutrophils and M2 macrophages were calculated by tissue biopsy and hematoxylin-eosin (HE) staining. Data analysis was performed with ANOVA test and LSD Post-Hoc Test. The average levels of serum TNF-? on the 14-day were 394.50; 180.33; 2,980.33; and 607.42 pg/ml for X1, X2, C1 and C2, respectively. The average neutrophils number on the 14-day were 8.00; 6.83; 14.67; and 11.17 for X1, X2, C1 and C2, respectively. The average macrophage number in the 14-day was 15.50; 19.17; 6.33; and 11.17 for X1, X2, C1 and C2, respectively. We found significant differences between TNF-? levels, the number of neutrophils, and the number of M2 macrophages. The administration of S. platensisextract at a dose of 750 mg/ kgBW/day reduces serum TNF-? levels, neutrophil count, and increases M2 macrophages in skin incisional mice model.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.

Methanol poisoning is a hazardous intoxication characterized by visual impairment and formic acidemia. The therapy for methanol poisoning is alcohol dehydrogenase (ADH) inhibitors to prevent formate accumulation. Ranitidine has been considered to be an inhibitor of both gastric alcohol and hepatic aldehyde dehydrogenase enzymes. This study aimed at testing ranitidine as an antidote for methanol acute toxicity and comparing it with ethanol and 4-methyl pyrazole (4-MP). This study was conducted on 48 Sprague-Dawley rats, divided into 6 groups, with 8 rats in each group (one negative control group [C1], two positive control groups [C2, C3] and three test groups [1, 2 and 3]). C2, C3 and all test groups were exposed to nitrous oxide by inhalation, then, C3 group was given methanol (3 g/kg orally). The three test groups 1, 2 and 3 were given ethanol (0.5 g/kg orally), 4-MP (15 mg/kg intraperitoneally) and ranitidine (30 mg/kg intraperitoneally), respectively, 4 hours after giving methanol. Rats were sacrificed and heparinized, cardiac blood samples were collected for blood pH and bicarbonate. Non-heparinized blood samples were collected for formate levels by high performance liquid chromatography. Eye balls were enucleated for histological examination of the retina. Ranitidine corrected metabolic acidosis (p = .025), decreased formate levels (p = .014) and improved the histological findings in the retina induced by acute methanol toxicity.

ABSTRACT Background: Recent studies showed that Interleukin-8 (IL-8), activated cytokine immune response which plays an important role in the development of acute and chronic gastritis. Harmless anti-inflammatory therapeutic alternatives have been proposed, for example, the consumption of Sechium Edule Jacq. Swartz (chayote). Antioxidant (flavonoid) and cell regeneration (alkaloid) agents were found in chayote. This study aimed to determine the effect of chayote Sechium Edule Jacq. Swartz extracts on the level of IL-8 in Wistar rats with aspirin- induced gastritis. Subjects and Method: This was a randomized controlled trial (RCT) conducted at the laboratory of Mathematics and Natural Science, Universitas Sumatra Utara from January to February 2020. A total of 35 male Wistar rats was selected for this study and randomly allocated into 7 groups: (1) Negative control; (2) Positive control; (3) 100 mg/ kg BW chayote ethanol extract ; (4) 200 mg/kg BW chayote ethanol extract; (5) 100 mg/ kg BW chayote ethyl acetate fraction; (6) 200 mg/kg BW chayote ethyl acetate fraction; and (7) 20 mg omeprazole. The rats in positive control and treatment groups were induced with aspirin (200mg/ kg BW). The negative control group received no intervention. The dependent variable was level of IL-8 measured by ELISA. The independent variables were treatment status. The data were analyzed by One Way Anova and post hoc test. Results: The mean differences of IL-8 level were not statistically significant between study groups (p= 0.327). Mean of IL-8 level was higher in positive control group (Mean= 160.80; SD= 6.90) than in negative control group (Mean= 141.20; SD= 10.98). The lowest IL-8 level was in 100mg/ kg BW chayote ethanol extract group (Mean= 149.94; SD= 40.4), followed by 200mg/ kg BW (Mean= 152.4; SD= 30.73) and 100mg/ kg BW (Mean= 164.60; SD= 25.04) chayote ethyl acetate fraction groups, 20 mg omeprazole group (Mean= 170.60; SD= 21.58), and 200 mg/ kg BW chayote ethanol extract group (Mean= 176.80; SD= 10.98). Conclusion: The low dose (100mg/ kg BW) chayote ethanol extract has the most potential antiinflammation effect on in vitro gastritis with the lowest IL-8 level of all doses of chayote ethanol extract, chayote ethyl acetate fraction, and omeprazole.

Objective: The aim of this work was to study the biochemical characteristics of coconut milk and its antigenic effect on the Balb/c mice immunized with α-lactalbumin protein, as well as its consequences on the structure of the intestinal epithelium.Methods: To achieve the objective of the study, an electrophoresis was realised on a polyacrylamide gel to determine various proteins contained in coconut milk. In addition, Lowry’s method was used to determine the amount of proteins in the formula. The antigenicity of coconut milk in sera was also studied using the Enzyme-Linked Immunosorbent Assay (ELISA) method. For the histological study, 21 w-old mice Balb/c were used and distributed in three groups of 7 mice each. Group 1, received a standard feed with no treatment (Negative control), group 2 and 3 received respectively a standard feed (Positive control) and coconut milk for a period of 28 d after being immunized with α- lactalbumin.Results: Analysis of the data revealed that the rate of proteins of cow’s milk is higher than that of the coconut milk ( p0.01). However, after carrying out the electrophoresis analysis, the coconut milk showed the absence of intact proteins. The anti α-Lactalbumin IgG titers significantly increased in positive control groups that received coconut milk (p<0.0001). Moreover, there was an increase of the intestinal villi height of mice fed with coconut milk, in the structure level of their intestinal epithelium compared to the negative control group.Conclusion: The findings of the study provide the evidence that coconut milk is a possible alternative to the cow’s milk formula in case of allergy.
