Tratamento orgânico de resíduos de rúmen bovino

The organic wastes need to be adequately managed, in order to avoid the environmental pollution and damage to the public health. So, this work aimed to study the composting process using two methods: manual and mechanized, for the treatment of bovine ruminal waste. This residue is generated in large proportions during the bovine slaughter process, and it can lead environmental degradation and contamination, or even damage to the public health, when not treated. For the initial adjustment of the composting parameters, it was incorporated the residue of coffee husks. The manual composting system was done by the manually aerated piles, while the mechanized composting system was done in a reactor coupled to a compressor that enabled the aeration of the system. The proportions used in both systems were: 90% bovine rumen (R) and 10% coffe husks (CC); 85% bovine rumen and 15% coffe husks; 80% bovine rumen and 20% coffe husks. The parameters determined during the monitoring of the composting process were: temperature, pH, moisture, organic matter, ash, organic carbon, Kjeldahl nitrogen and C/N ratio. The results obtained during the monitoring of the piles and reactors presented similar behavior, except for the parameters Kjeldahl nitrogen and C/N ratio. When compared to the “Instrução Normativa no 25 de 23/07/2009 do Ministério da Agricultura, Pecuária e Abastecimento”, the organic produced composts with the best results were: pile 2 (85% R; 15% CC) and reactors 1 (90% R; 10% CC) e 2 (85% R; 15% CC)

Proliferação e Morte Celular (Apoptose) avaliadas em ratos Lewis após tratamento com mistura de praguicidas em baixas doses

The use of pesticides in Brazil has intensified over the years. And since 2009 it was ranked as the largest market for pesticides worldwide. The consequential diffuse contamination of the environment is therefore due to the increasing number of chemicals of different classes, origins and modes of action. Little is known about the action of pesticides on human health in situations of co-exposure. Possible toxic effects are not restricted to agricultural and industrial workers, but also the general population that may be exposed continuously to its residues in food and water. Although these pesticides are mostly present in the environment at low doses, it must be considered that possible cumulative or synergistic effects may occur when there are concurrent or sustained exposure for two or more of these agents, which can lead to late manifestation of subclinical damages, sometimes irreversible. Thus, the specific objective of this study was to assess the effect of carcinogenesis promotion of a mixture of pesticides at low doses and analyze the phenomena of cell proliferation and apoptosis in rat liver. A total of 50 male Lewis rats was separated into 5 groups for 8 weeks in a medium term hepatocarcinogenesis model. The three different classes of pesticides (dieldrin, dicofol, endosulfan, dichlorvos and permethrin), whose residues were detected by ANVISA during the period from 2001 to 2005 in tomatoes cultures, were added to the feed of rats initiated to hepatocarcinogenesis with diethylnitrosamine (DEN- 200mg/kg ip). We used two different mixtures, one with no toxic effects at doses (MEX1) referring to the NOEL (no-observed-effect level) and another at doses LOEL / LEL / LOAEL (Lowest-observed-effect level / Lowest-effect level / Lowest -observed-adverse-effect level), to the installation of adverse effects (MEX2), derived from chronic studies.

Avaliação dos aspectos dosimétricos no tratamento de câncer de tireóide com Iodo-131

The 131I (radioactive iodine) is one of the most used radionuclides in nuclear medicine for diagnosis and treatment. The present study evaluates the dosimetric aspects related to radioiodine therapy after thyroidectomy in patients with thyroid cancer. The samples were studied with 50 patients undergoing treatment, by assessing the exposures of workers (nursing assistants, staff hygiene, medical and physical), the general public (accompanying and family members) and on the environment. To evaluate the workers, was made a survey of the environmental conditions of the room radioiodine and routines adopted by them during the treatment period. Estimating the dose equivalent per month for each employee, we observed that the maximum levels obtained for nursing assistants, the team of hygiene, medical and physicians were considered low in relation to the extent permitted by law. In order to assess the public, some situations have been suggested for the calculation of equivalent doses in which it was possible to verify the fundamental importance of isolating the patient in the 2 days first. Regarding the environment, the radioactive waste generated by patient had volume of 1.0 m3 and activity estimated at 0.91 mCi, taking a decay time for eliminating them about 75 days to reach the allowable value of 2 μCi / kg system of collecting garbage. Therefore, all radioactive waste removed from the patient's room should be sent to the warehouse for temporary storage of radioactive waste, located away from normal work areas
