Immunomodulator is an ingredient or drug that can modulate immune system functions and activities. This study was conducted to determine the effect of ethanol extract of Melophlus sarasinorum sponge on macrophage phagocytosis activity. Twenty four male mice balb/c were divided into six groups. The first group received 100 mg/kg of ethanol extract of Melophlus Sarasinorum sponge, the second group received 200 mg/kg of ethanol extract of Melophlus sarasinorum sponge, the third group received 300 mg/kg of ethanol extract of Melophlus Sarasinorum sponge and the fourth group received 400 mg/kg of ethanol extract of Melophlus Sarasinorum sponge. The positive control group received Phyllanthus niruri linn extract (Stimuno®) 0,13 mg/g and the negative control group received NaCMC 0,5%. The extract was orally administered from first day to seventh day. On the eighth day, each of the mice was injected Staphylococcus aureus bacteria (SA) 0.5 mL intraperitoneally. Macrophage cell activity is calculated from smears of peritoneal fluid of mice. Increased doses of ethanol extract of Melophlus sarasinorum sponge increase the amount of macrophage phagocytosis activity that are 25,25% (negative control), 61,5% (positive control), 55,75% (100 mg/kg), 60,75% (200 mg/kg), 62,25% (300 mg/kg) dan 66,25% (400 mg/kg). The results showed that the ethanol extract of Melophlus sarasinorum sponge has the potential as immunomodulator at a doses of 300 mg/kgBB and 400 mg/kg with no significantly different effectiveness with positive control in increasing macrophage cell phagocytosis activity based on the result of post-hoc statistical test of Tukey (sig.> 0,05).

SUMMARY This in vitro study evaluated the effect of six surface treatments on the shear bond strength of three resin-modified glass ionomers (RMGIs) to dentin. Occlusal surfaces of caries-free third molars were reduced to expose only dentin. Surface treatments were smear layer intact (negative control), Cavity Conditioner, EDTA, Ketac Primer, Self Conditioner, and etching with 35% phosphoric acid followed by the application of Optibond Solo Plus. Filtek Z250 composite resin bonded with Optibond Solo Plus served as a positive control. Conditioning agents were used according to the manufacturers' instructions. After surface treatments, Fuji II LC, Riva LC, Ketac Nano, and Filtek Z250 were placed in copper-band matrices 5 mm in diameter and 2 mm in height and were light-cured for 20 seconds. Specimens were stored in 100% humidity for 24 hours, after which they were placed in deionized water for 24 hours at 37°C. They were then tested under shear forces in an Instron Universal Testing Machine at a crosshead speed of 0.5 mm/min. A two-way analysis of variance and Tukey honestly significant difference statistical analyses (p&lt;0.05) indicated significant interaction between RMGIs and conditioning agents. Acid etching followed by Optibond Solo Plus provided highest bond strengths for all three RMGIs, which were not statistically different from the positive control.

Introduction The aim of this in vitro study was to assess and compare the effect of different intermediary bases on microleakage between tooth and a nanocomposite interface in Class II box cavities in primary teeth. Methods Standard Class II box cavities were prepared in 52 primary molars and randomly divided into 9 groups according to the intermediary base used (Multicore Flow, Fuji II LC, SDR, Smart Dentin Replacement, and Biodentine). All specimens were subjected to thermocycling and prepared for microleakage testing and evaluation. Results There was significant difference in the mean ranks of microleakage between the 9 groups, which was observed in the gingival side (p<0.0001) and the occlusal side (p<0.0001). The mean ranks microleakage was significantly higher with experimental SDR, experimental Multicore Flow, and positive control materials when compared with the other 6 groups. The microleakage mean ranks were statistically significantly lower in experimental Fuji II LC, experimental Biodentine, and all negative control groups when compared with the other 3 groups. Conclusions Microleakage is affected by the application of intermediate material. Experimental Biodentine and Fuji II LC showed the lowest microleakage while experimental SDR and experimental Multicore Flow showed the highest microleakage.

AbstractThere is a need for new targets to specifically localize inflammatory foci, usable in a wide range of organs. Here, we hypothesized that the cleaved molecular form of CD31 is a suitable target for molecular imaging of inflammation. We evaluated a bioconjugate of D-P8RI, a synthetic peptide that binds all cells with cleaved CD31, in an experimental rat model of sterile acute inflammation. Male Wistar rats were injected with turpentine oil into the gastrocnemius muscle two days before 99mTc-HYNIC-D-P8RI (or its analogue with L-Proline) SPECT/CT or [18F]FDG PET/MRI. Biodistribution, stability study, histology, imaging and autoradiography of 99mTc-HYNIC-D-P8RI were further performed. Biodistribution studies revealed rapid elimination of 99mTc-HYNIC-D-P8RI through renal excretion with almost no uptake from most organs and excellent in vitro and in vivo stability were observed. SPECT/CT imaging showed a significant higher 99mTc-HYNIC-D-P8RI uptake compared with its analogue with L-Proline (negative control) and no significant difference compared with [18F]FDG (positive control). Moreover, autoradiography and histology revealed a co-localization between 99mTc-HYNIC-D-P8RI uptake and inflammatory cell infiltration. 99mTc-HYNIC-D-P8RI constitutes a new tool for the detection and localization of inflammatory sites. Our work suggests that targeting cleaved CD31 is an attractive strategy for the specific in vivo imaging of inflammatory processes.

Objective: The current study was carried out to evaluate the anthelmintic activity of the rhizome extract of Curcuma longa as an alternative source of effective remedies for nematodiasis.Methods: The anthelmintic activity of the C. longa was assessed in vitro against Haemonchus spp., a gastrointestinal (abomasum) parasite of goats. Different concentrations of the extracts (1 mg/mL, 2.5 mg/mL, 5 mg/mL, and 10 mg/mL) in phosphate-buffered saline (PBS) were tested, and the results expressed in terms of time of paralysis (minute) and time of death (minute) of the worms. Albendazole (1 mg/mL) was used as a reference (positive control) and PBS as a control group (negative control).Results: The qualitative phytochemical analysis of the methanolic extract (ME) of the plant disclosed the presence of alkaloids, glycosides, terpenoids, flavonoids, tannins, saponins, phenol, anthraquinone, and carbohydrates; whereas, the aqueous extract (AE) showed the presence of alkaloids, carbohydrate, flavonoids, and saponins. Both ME and AE of the C. longa (rhizome) expressed significant efficacy (p≤0.05) in causing paralysis as well as the death of the worms within 12 h of exposure at all tested concentrations, as compared to the negative control. The rhizome extracts of C. longa showed dose-dependent efficacy in causing paralysis of the worm motility and the final progression to death. The results showed that the ME at 10 mg/mL was significantly more potent (p≤0.05) over the AE.Conclusions: This study concluded that the rhizome extract of C. longa exhibited potent anthelmintic efficacy against the nematode parasite, Haemonchus spp.
