Efeito da desinfecção e do tempo de armazenagem na molhabilidade de moldes de alginato

The cares at the manipulation of the alginate (condensation, disinfection of the impression and the time elapsed until the leak of the plaster) deserve special attention considering the great amount of distortions occurring every time the impression is not fill of plaster in a brief space of time and appropriate storage conditions. Besides its adaptation to the plaster suffers influence of the events happened after the impression is removed of the mouth. The purpose of this research was to evaluate the wetting capacity of three brands of alginate (Jeltrate™,Hydrogum™ e Orthoprint™) by the plaster type III (Rio™) under the influence of disinfection by sodium hypochlorite 1% sprays and the time of storage of 15 minutes,30 minutes, 1 hour, 6, 12 and 24 hours. There were made 60 impressions of each brand of alginate divided in two groups (water and sodium hypochlorite 1%) rearranged after the application of the sodium hypochlorite spray according to the storage time (15 or 30 minutes and 1,6,12, or 24 hours). On the surface of the impressions 2ml of plaster were flowed, proportioned and condensed in agreement with manufacturer‘s instructions. After the final setting expansion the casts were sectioned vertically and medially, regularized at the cut surface (emery paper 400) and setted for reading the contact angle at the microscope Carl Zeiss. The obtained results, submitted to statistical treatment (ANOVA) revealed significant differences when compared the employed solutions (water and sodium hypochlorite 1%) and the time of storage. The sodium hypochlorite 1% exhibited the smallest contact angles and the times of storage of 15 minutes and 6 hours the smallest and larger angles, respectively. It can be concluded that the alginate impressions exhibited larger adaptation to the plaster when disinfected by hypochlorite of sodium 1% and stocked by 15 minutes.

Adição de plasma bovino em salmouras para injeção de coxão duro bovino (m. Biceps femoris) e seus efeitos no pH e na carga microbiana de bifes cozidos embalados à vácuo e mantidos sob refrigeração

The physical (pH) and microbiological (psychotrofi c microorganisms and lactic bacteria) characteristics of beef outside round (m. Biceps femoris) injected (15%) with brines free of polyphosphates containing and sodium lactate or sodium lactate and sodium diacetate and liquid bovine plasma (PLL and PLO) or dehydrated bovine plasma (PDL, PDO) were evaluated along with beef cuts injected with brines free from plasma, but containing polyphosphates and bacteriostatic agents (CL and CO) and non injected beef cuts (IN), comprising seven treatments of cooked and vacuum packaged beef steaks stored under refrigeration (6ºC) during 43 days. No differences in pH were detected among raw or cooked injected treatments, although IN showed lower pH value in raw beef cuts. The addition of liquid or dehydrated bovine plasma did not affect the microbial load after whole muscles pasteurization, but increased the bacterial counts in cooked beef steaks during refrigerated storage, comparing to treatments with no plasma addition (CL and CO). The storage temperature (6ºC), usually found during commercialization of meat increased the microorganisms growth rate affecting the microbiological quality, especially when plasma was added to the brine.

Investigação da poluição por metais tóxicos no córrego do Cintra

Cintra stream is the major receiver of treated effluent from sanitary, hospital and research laboratory sewage from the UNESP campus in Botucatu, Rubião Júnior District, São Paulo state; and it has shown evidence of diffuse contamination by metals along it. Analyses of the most toxic metals (Pb, Cu, Fe, Ni and Zn) were carried out by using an atomic absorption spectrometer AA-6.800 - Perkin Elmer, analyst 700. ANOVA followed by the Tukey test were used for data analyses at 5% significance level. The main objective of this study was to compare current data on metal levels with data from other studies, in the same area, and of the same nature, conducted before and after implementation of chemical residue management by the university in 2008. Also, it aimed at identifying and quantifying possible diffuse and punctual contamination. Sites S1 and S2 showed punctual contamination, while diffuse sources were observed between S4 and S5. The quality of water in the Cintra Stream improved after establishment of the program of laboratory chemical residue management in the Campus of UNESP.
