ABSTRACT This study demonstrated the capacity of bacteriocin-producing lactic acid bacteria (LAB) to reduce intestinal colonization by vancomycin-resistant enterococci (VRE) in a mouse model. Lactococcus lactis MM19 and Pediococcus acidilactici MM33 are bacteriocin producers isolated from human feces. The bacteriocin secreted by P. acidilactici is identical to pediocin PA-1/AcH, while PCR analysis demonstrated that L. lactis harbors the nisin Z gene. LAB were acid and bile tolerant when assayed under simulated gastrointestinal conditions. A well diffusion assay using supernatants from LAB demonstrated strong activity against a clinical isolate of VRE. A first in vivo study was done using C57BL/6 mice that received daily intragastric doses of L. lactis MM19, P. acidilactici MM33, P. acidilactici MM33A (a pediocin mutant that had lost its ability to produce pediocin), or phosphate-buffered saline (PBS) for 18 days. This study showed that L. lactis and P. acidilactici MM33A increased the concentrations of total LAB and anaerobes while P. acidilactici MM33 decreased the Enterobacteriaceae populations. A second in vivo study was done using VRE-colonized mice that received the same inocula as those in the previous study for 16 days. In L. lactis-fed mice, fecal VRE levels 1.73 and 2.50 log10 CFU/g lower than those in the PBS group were observed at 1 and 3 days postinfection. In the P. acidilactici MM33-fed mice, no reduction was observed at 1 day postinfection but a reduction of 1.85 log10 CFU/g was measured at 3 days postinfection. Levels of VRE in both groups of mice treated with bacteriocin-producing LAB were undetectable at 6 days postinfection. No significant difference in mice fed the pediocin-negative strain compared to the control group was observed. This is the first demonstration that human L. lactis and P. acidilactici nisin- and pediocin-producing strains can reduce VRE intestinal colonization.

The objective of this study was to evaluate the use of the Kowa HA-2 applanation tonometer in measuring intraocular pressure (IOP) in cats. Ten healthy eyes were used in an ex vivo study in which the calibration curve for manometry vs. tonometry was determined by artificially raising the IOP in 5 mmHg increments up to 60 mmHg (10-60 mmHg). Both eyes of 10 anesthetized cats were studiedin vivo to compare manometry vs. tonometry. In the ambulatory study, 78 healthy eyes, 7 eyes with glaucoma and 20 eyes with uveitis were evaluated by tonometry, which was performed with topical anesthesia and 1% fluorescein eye drops for the formation of fluorescein semicircles. The correlation coefficient (r²) between the manometer and the Kowa HA-2 tonometer was 0.993 and the linear regression equation was y = 0.0915x + 0.0878 in the ex-vivo study. In the in vivo study, the IOP values (mean±SD, in mmHg) in manometry were 15.6 ± 1.1(14.0 – 17.5) and in tonometry were 15.5 ± 1.2(13.5 – 17.2), with no significant difference (P > 0.05) between manometry and tonometry. In ambulatory study, using the Kowa HA-2 tonometer, the IOP values (mean±SD, in mmHg) were 15.0 ± 1.5 (11.8 – 18.3) for the healthy eyes, 38.4 ± 8.1(29.6 – 53.7) for glaucomatous eyes and 10.4 ± 2.0(5.3 – 12.2) for eyes with uveitis. There was a strong correlation and accuracy between the IOP values with the manometry and the Kowa HA-2 tonometer. In the ambulatorystudy the IOP values obtained with the tonometer were compatible for animals with healthy eyes and with clinical signs of glaucoma and uveitis. We conclude that the Kowa HA-2 tonometer can be used in the measurement of IOP in cats, since it is a practical and accurate method in this species.

AIM: To assess dimensional change and antimicrobial activity of disinfectants substances incorporated during the dental stone manipulation. MATERIAL AND METHOD: In vivo - microorganisms were collected in alginate molds of 30 volunteers inoculated on BHI agar and incubated at 37 °C for 24 hours. The molds were cast with type IV gypsum, manipulated with saline (G1), 1% sodium hypochlorite (G2) and 4% chlorhexidine (G3), replacing the water. After setting of plaster with 1 hour two collections on models were made. After 24 hours, the readings were performed. The Kruskal-Wallis and Wilcoxon tests with confidence interval of 99% and 95% respectively were used. In vitro - Müeller Hinton agar petri dishes were inoculated with S. mutans (ATCC25175), S. sanguis (ATCC10556) and E. faecalis (ATCC29212), over which were placed steel rings filled with the same substances of the in vivo study. After deposition of gypsum and incubation, halos were measured with a digital caliper and data were submitted to ANOVA and Tukey's test with confidence interval of 95%. Dimensional Change - With a metallic matrix and a perfectly adapted tray, the insertion axis and force used for moulding and obtain 30 specimens in type IV gypsum were standardized, following the same distribution of the study groups in vivo. The specimens were measured by Image Pro Plus software and data were submitted to ANOVA and Tukey's test with confidence interval of 95%. RESULT: Data from the in vivo study demonstrated a significant difference between the mold and each model (p<0.001). In the Wilcoxon test there was no significant difference between groups of models. At the in vitro test, G2 showed greater inhibition zones in all micro-organisms tested compared to G3, but with respect to dimensional changes, there was a significant difference between solutions and metallic standard, where G3 caused less change than G2. CONCLUSION: Chlorhexidine 4% showed to be the most suitable disinfectant.

ABSTRACT Objectives: The aim of this in vivo study was to investigate the preventive effect of two different adhesives on enamel demineralization and compare these adhesives with a conventional one. Materials and Methods: Fifteen patients requiring the extraction of their first four premolars for orthodontic treatment were included in the study. One premolar was randomly selected, and an antibacterial monomer-containing and fluoride-releasing adhesive (Clearfil Protect Bond, Kuraray Medical, Okayama, Japan) was used for orthodontic bracket bonding. Another premolar was randomly selected, and a fluoride-releasing and recharging orthodontic adhesive (Opal Seal, Ultradent Products, South Jordan, Utah) was used. One premolar was assigned as a control, and a conventional adhesive (Transbond XT, 3M Unitek, Monrovia, Calif) was used. The teeth were extracted after 8 weeks, and the demineralization areas of the 45 extracted teeth were analyzed using microcomputed tomography with software. Results: There was no significant difference between the white spot lesion (WSL) rates of the adhesives (P &gt; .05). The volumes of the WSLs varied from 0 to 0.019349 mm3. Although Opal Seal showed the smallest lesion volumes, there was no significant difference in volumetric measurements of the lesions among the groups (P &gt; .05). Conclusions: The findings indicated no significant differences between the preventive effects of the adhesives used in this in vivo study over 8 weeks.

Saliva is a complex secretion consisting of 99% of water and remaining 1% of organic and inorganic molecules. Sucrose and starches are the predominant dietary carbohydrates in modern societies. Among all the foods consumed by children, chocolates and biscuits are the most common. Therefore this present in vivo study was conducted to assess the acidogenic effect of commercially available biscuits on salivary pH among 10 to 15 years old children. Study Design used in the study was In Vivo clinical study (Pilot Trail). The population collected in the survey was children between the age group of 10 - 15 years old children. 4 Groups were considered and 10 in each group. Group 1: Hide and Seek, Group 2: Good Day, Group 3: Dream and Cream, Group 4: Oreo. Sampling method used in the study was conducted as simple random sampling. Ethical approval of the study was obtained from Saveetha Institutional Review Board. Informed consent of the children were obtained from the parents. Descriptive statistics were expressed by means of mean and standard deviation. Shapiro Wilks test used to test the normality of the data set. Kruskal Wallis test was used to find the difference in mean Salivary pH between the groups and within the groups at Baseline, Immediate and after 15 min, 30 mins. A statistically significant difference in mean Salivary pH was observed between the groups at Immediate and after 30 mins (p<0.05). The mean Salivary pH was significantly dropped in Oreo, Dream cream and Hide & Seek groups at various time-periods. Based on the results of the present study, it can be concluded that maximum drop in mean salivary pH was observed in Group IV followed by Group II and Group I. It was observed that in all the groups, the pH gradually got back to near normal levels due to the buffering mechanism of saliva.
