Abstract: the influence of reforestation was evaluated during two season periods (february and october) in sites planted with corymbia citriodora and leucaena_leucocephala through microorganism counts (bacteria, fungi, actinomycetes, and nitrite oxidizers) and microbial activity (respiratory and urease activities). an atlantic forest and a bare soil site were used as controls. the general trends of the variables in the different soils were: atlantic forest or l. leucocephala > c. citriodora > bare soil. the microbial populations in l. leucocephala and c. citriodora soils were significantly higher (p < 0.05) than that found in the bare soil. similar results were obtained for respiratory and urease activities. the microbiological variables of the soil under l. leucocephala were comparable or even superior to that found under atlantic forest. an improvement in the microbiological soil variables was observed in the soil under c. citriodora when compared to the soil without vegetation. these results can be attributed to an increasing amount of total organic c of the soils under l. leucocephala and c. citriodora in relation to the soil without vegetation. although most results obtained in february presented higher values than in october, the sampling period did not have a consistent controlling influence on these variables.

International Archives of Otorhinolaryngology , 2013,
Abstract: Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

Abstract: background: the auditory steady state response (assr) is an electrophysiological procedure that evaluates, at the same time, the hearing thresholds of both ears at various frequencies. this procedure reduces the time of testing and enables the stimulation of levels close to 125db hl, characterizing residual hearing. aim: to verify the applicability of the assr to determine the hearing thresholds in different levels of sensorineural hearing loss. method: 48 individuals aged 7-30 years, with different levels of hearing loss were assessed. the pure tone audiometry (pta) and the assr were carried out in following carrier frequencies 0.5; 1; 2 and 4k hz. the carrier frequencies in the assr were modulated in amplitude and frequency, with multiple dicotic stimulation for mild and moderate hearing loss. simple stimulation was used to test the other hearing deficit levels. results: there was a significant association (p<0.01) between the thresholds obtained in the pta and in the assr for all of the tested frequencies, especially for the severe levels. however, for some patients, the hearing loss level was overestimated in the assr. conclusion: the assr can be used to estimate the pta threshold; nevertheless, it should not be analyzed in an isolated way, but seen as a complementary procedure to the behavioral auditory assessment.
