ABSTRACT
BACKGROUND: Cigarette smoke contains a large number of types of oxygen free radicals and cytotoxic components. Passive smoking will impair respiratory and cardiovascular system functions, and result in oxidative damage of skeletal muscle and decreased exercise ability. OBJECTIVE; To investigate the effect of phellinus igniarius crude polysaccharides on the exercise capacity and free radical metabolism of skeletal muscle in mice suffering passive smoking, so as to provide ideas for the prevention and treatment of peroxidative damage of skeletal muscle and depression of exercise capacity in rats suffering passive smoking. METHODS: Twenty-one male Kunming mice were randomly assigned to three groups: Gavage with phellinus igniarius crude polysaccharides and suffering passive smoking (phellinus group), gavage with distilled water and suffering passive smoking (control group), and only gavage with distilled water (blank group). After 4 consecutive weeks, the mice were forced to take an exhausted swimming, and sacrificed subsequently. Exhausted swimming time was recorded. The bilateral gastrocnemius muscle tissues were obtained, in which the vitality of superoxide dismutase, catalase, glutathion reductase and Ca2+-Mg2+-ATP and Na+-K+-ATP activity, and the concentration of malonaldehyde were measured. RESULTS AND CONCLUSION: (1) The swimming time of mice in the control group was shorter than that in the blank group (P 0.6, P 0.6, P < 0.05), and negatively correlated with the concentration of malonaldehyde (r < -0.6, P < 0.05). (5) In summary, phellinus igniarius crude polysaccharides can improve the antioxidative enzyme activity of skeletal muscle, inhibit lipid peroxidation reaction, and thus increase exercise ability of mice suffering passive smoking. The study was approved by the Ethical Committee of Jiangxi Normal University, approval No. 201703.
ABSTRACT
O objetivo com este estudo foi estabelecer os intervalos de referência de diferentes analitos séricos em Ozotoceros bezoarticus bezoarticus de vida livre. Foram coletadas amostras de sangue de 54 fêmeas e 14 machos adultos, capturados no Pantanal de Mato Grosso do Sul. A determinação das concentrações de cálcio total, albumina, colesterol total, creatinina, glicose, fósforo, proteína total, triglicerídeos e ureia séricas e a atividade das enzimas alanina aminotransferase, aspartato aminotransferase, creatina quinase fração MB e fosfatase alcalina foi realizada em equipamento automático. Valores de globulinas, cálcio total e proporções (razões) entre analitos foram realizados por meio de cálculo matemático. Esta é a primeira descrição do intervalo de referência de parâmetros bioquímicos séricos em veado-campeiro de vida livre do Pantanal de Mato Grosso do Sul. O tamanho da amostra e a distribuição dos dados indicam que os valores médios obtidos são representativos e podem ser usados para a monitorização da saúde, do estado nutricional e do diagnóstico de enfermidades nesse estrato populacional.(AU)
The objective of the present study is to establish the reference intervals of different serum analytes in free - living Ozotoceros bezoarticus bezoarticus. Blood samples were drawn from the 54 females and 14 males, adults, captured in the Pantanal of Mato Grosso do Sul. A determination of total calcium, albumin, total cholesterol, creatinine, glucose, phosphorus, total protein, triglycerides, and serum urea concentrations and an activity of the enzymes alanine aminotransferase, aspartate aminotransferase, creatine kinase MB fraction and alkaline phosphatase were performed in automated equipment. Values of globulins, total calcium and proportions among analytes were performed by means of mathematical calculations. This is a first description of the reference parameters for serum biochemistry of free - living pampas deer in the Pantanal of Mato Grosso do Sul. Sample size and distribution of data indicate that the mean values obtained are representative and can be used for a health monitoring, nutritional status, and diagnosis of diseases in this population stratum.(AU)

O artigo pretende desenvolver o argumento de que a noção de carne (chair, em francês) - que constitui o conceito mor da ontologia selvagem de Maurice Merleau-Ponty - pode funcionar como uma referência ontológica para a noção winnicottiana de mãe suficientemente boa. Para tanto, numa primeira parte descreve-se a noção de carne; em seguida, a noção de mãe suficientemente boa para, por fim, articular os dois níveis de teorização: o ontológico e o ôntico, numa relação em que um nível referenda o outro, discriminando, nesse mesmo processo, o espelho materno winnicottiano do lacaniano (já que este último implica, necessariamente, uma alienação do bebê no desejo da mãe).
This article intends to develop the argument that the notion of flesh (chair, in French) - which constitutes the principal concept of Merleau-Ponty's savage ontology - can work as an ontological reference for Winnicott's notion of good enough mother. For this purpose, it describes the notion of flesh; then, the notion of good enough mother, to finally articulate both levels of theorization: the ontological and the ontic ones, in a relation of mutual reference. At the same time, it discriminates Winnicott's conception of maternal mirror from Lacan's one (since this one implies, necessarily, an alienation of the baby in the mother's desire).
ABSTRACT
Objective To evaluate the application and initial experience of laparoscopy in kidneypreserving surgery for savage giant hydronephrosis. Methods This series included 6 cases of savage gianthydronephrosis (2 men and 4 women;age range,15 -57 years;mean age,28 years).Of them 5 cases weredetected when visiting doctors due to flank pain,abdominal mass,and the rest one by B-ultrasound duringpregnancy.Four cases had hydronephrosis on the left;and 2 cases,on the right.The quantity of hydronephro-sis was 2250 -8300 ml,respectively.None had development on IVU examination.Of them,3 cases had con-genital ureteropelvic junction (UPJ) obstruction;2 had multiple stones in infracalices secondary to UPJ ob-struction;1 had stones in pelvis with polyp formation.Relieving obstruction,pyeloplasty,nephroplication andnephropexy were performed via laparoscope. Results All the operations were successful.The operativetime was 2.5 -5.0 h;the blood loss was 50 -150 ml,and the mean postoperative hospital stay was 7.2 d.The postoperative follow-up ranged from 3 to 24 months. Three months after operation,B-ultrasound showedthat giant hydronephrosis was markedly relieved in 5 cases (the renal sinus separation was 1.8 m,2.0 cm,2.5 cm,2.5 cm and 2.8cm,respectively),and in the rest 1 case the kidney was slightly smaller than nor-mal.IVU examination was performed every 3 months after operation, and different degrees of developmentappeared in all cases.During the follow-up,no obvious ureteropelvic anastomotic stricture was found on retro-grade pyelography (RGP). Conclusions The protective renal treatment via laparoscopy for savage gianthydronephrosis is a feasible and minimally invasive technique that provides the same clinical and radiograph-ic results as open operation.
