Monitoramento de variáveis de qualidade da água do Horto Ouro Verde - Conchal - SP

O presente trabalho foi desenvolvido em área do Horto Ouro Verde, de propriedade da International Paper do Brasil, localizado no município de Conchal - SP, tendo por objetivo monitorar algumas variáveis de qualidade da água em duas condições do uso do solo (mata nativa e eucalipto). Para tanto, coletou-se água mensalmente em seis pontos ao longo do curso d'água, de maneira representativa dos diferentes usos do solo. As variáveis analisadas foram temperatura (T), oxigênio dissolvido (OD), matéria orgânica (MO) e potencial hidrogeniônico (pH). Foram encontradas diferenças significativas na matéria orgânica para os pontos P3 (mata nativa) e P6 (eucalipto), e no oxigênio dissolvido para os pontos P1 (mata nativa) e P6 (eucalipto), e quando comparadas às médias do somatório dos efeitos em cada tipo de manejo do solo, não houve diferenças significativas para todas as variáveis estudadas.

Background: Canine hip dysplasia (HD) is characterized by hip joint laxity and subluxation. It is the most common cause of osteoarthritis in dogs, especially in larger breeds. Its management includes nutritional supplements, nonsteroidal anti-inflammatory drugs, physical therapy, acupuncture or surgical procedures. Implantation of gold beads in acupuncture points and trigger points around a joint has been used in the treatment of osteoarthritis in dogs for at least 30 years. Gold bead implants(GBI) acts as continuous acupuncture stimulation and trigger point treatment in canine HD with long lasting results. Electrophysiological investigations of trigger points reveal dysfunctional muscle spindles which indicate that the electrical activity of active loci arises from extrafusal motor endplates.Case: This is a report on the use of acupuncture and GBI for bilateral HD in a nine year old female German Shepherd. The patient has a HD non-responsive to anti-inflammatory drugs and was unable to stand up or walk by its own. Radiographs showed marked dysplasia, significant subluxation with the femoral head partly out of a shallow acetabulum and massive secondary arthritic bone changes, mainly on the right side. The animal was submitted to eight acupuncture sessions with seven days interval. After the first acupuncture session the use of NSAID was interrupted. After eight weeks the dog was considered rehabilitated and underwent GBI in acupoints and trigger points as maintenance treatment. During the one-year follow-up period the improvement remained unchanged with no need of analgesics.Discussion: It has been suggested that acupuncture or GBI can treat the chronic pain resulting from osteoarthritis induced by HD. According to AP theory, GBI is permanent and long-lasting acupoint stimulation. Moreover, the method is inexpensive, quick and easy to perform, with no postoperative pain or need of exercise restriction. Although gold is extremely corrosion-resistant, the surface of the gold implants stimulates a reaction from the immune system causing an oxidative liberation of gold ions with anti-inflammatory actions. It is well known that gold ions are effective inhibitors of the respiratory burst of neutrophils and monocytes and the proliferation of lymphocytes. These findings suggest that gold implantation, on a local scale, mimics the anti-inflammatory and pain-relieving effect of drugs with chemically bound gold ions. The relatively slow speed of the process results in a limited liberation of gold ions securing that they are taken up almost exclusively by cells close to the implant. The nine year old female German shepherd had a positive response to acupuncture with pain relieve and locomotor rehabilitation. For the nine year old female German shepherd previous acupuncture sessions to GBI resulted in no post-implant worsening period. Indeed, the association acupuncture/GBI does not have the anti-inflammatory drugs undesirable effects and brings long lasting results. In conclusion, GBI therefore should be considered for canine HD when conservative or medical treatments fail to give the desired effect.

Acurácia do teste de escada utilizando o consumo máximo de oxigênio como padrão-ouro

Objective: To determine the accuracy of the variables related to the fixed-height stair-climbing test (SCT) using maximal oxygen uptake (V̇O 2 max) as the gold standard. Methods: The SCT was performed on a staircase consisting of 6 flights (72 steps; 12.16 m total height), with verbal encouragement, in 51 patients. Stair-climbing time was measured, the variables 'work' and 'power' also being calculated. The V̇O2 max was measured using ergospirometry according to the Balke protocol. We calculated the Pearson linear correlation (r), as well as the values of p, between the SCT variables and V̇O2 max. To determine accuracy, the V̇O 2 max cut-off point was set at 25 mL/kg/min, and individuals were classified as normal or altered. The cut-off points for the SCT variables were determined using the receiver operating characteristic curve. The Kappa statistic (k) was used in order to assess concordance. Results: The following values were obtained for the variable 'time': cut-off point = 40 s; mean = 41 ± 15.5 s; r = -0.707; p < 0.005; specificity = 89%; sensibility = 83%; accuracy = 86%; and k = 0.724. For 'power', the values obtained were as follows: cut-off point = 200 w; mean = 222.3 ± 95.2 w; r = 0.515; p < 0.005; specificity = 67%; sensibility= 75%; accuracy = 71%; and k = 0.414. Since the correlation between the variable 'work' and V̇O2 max was not significant, that variable was discarded. Conclusion: Of the SCT variables tested, using V̇O2 max as the gold standard, the variable 'time' was the most accurate.

Cavas históricas de ouro do Jaraguá: o que resta para se preservar?

The Historical Jaraguá Gold Caves are vestiges of excavations in weathered rock, dating back to the Brazilian colonial times, situated NW of Jaraguá peak, in the São Paulo municipality (SP). The areas were investigated to support historical preservation innitiatives. The excavations have lateral steep slopes and a narrow fat bottom zone, occupied by dense vegetation. The trace of the excavations is sinuous, trending N40-50W, in accordance to a transition zone of Neoproterozoic rocks: metapelites and metapsamites by the SW side and calc-silicate rocks and amphybolites at NE. The structural control results from three successive deformation phases. Urban expansion and road construction, during the last 30 years, have strongly impacted the areas: (I) Base of Quebra-Pé hill; (II) Jardim Britânia; (III) Morro Doce; (IV) Nova Anhangüera Park. A 5 th site was disfgured by earthworks. The Jardim Britânia area is partly discharacterized by earthflls; this however does not impede further protection actions. This framework allows to recommend authorities: (1) to permit immediate preservation of these areas; (2) to develop programs to build an integrated site for scientifc diffusion or an educational center for exhibition of rocks, ores and mineral samples; (3) to support the interest of some owners to preserve the area called Morro Doce, (4) to put forward a few proposals for educational use of the excavations, by production of feld guides on the historic sites. The alternatives will help keeping alive the memory of mining in the São Paulo State.
