Acupuntura no tratamento de discopatias intervertebrais em cães

The intervertebral disc disease is considered a major neurological disorder involving the spinal cord, being a disease commonly seen in dogs in clinical practice of small animals. The pathophysiology of most discopathies have not been fully elucidated, but it is known that the symptoms observed will depend on the severity of spinal cord compression and location of spinal injury, ranging from localized pain to complete paralysis. Through a detailed clinical examination and laboratory tests, we choose the most appropriate treatment for each patient, which can be conservative, through the use of anti-inflammatories, analgesics and acupuncture or surgical, through decompression techniques. Acupuncture, therapeutic method of ancient Chinese medicine, uses the stimulation of specific points on the body in order to balance the body's physiological. The action mechanism of acupuncture in discopathies has not been fully elucidated, but its analgesic effects, anti-inflammatory and restoration of sensory and motor function are known, showing results as good as surgical therapy

Efeito da silibinina sobre o fator de transcrição nuclear-kB e produção de citocinas inflamatórias por células mononucleares de gestantes portadoras de pré-eclâmpsia

Pre-eclampsia (PE) is a complication of human pregnancy characterized by hypertension and proteinuria after 20 weeks of gestation. Its incidence varies from 5% to 7% of pregnancies and is a major cause of morbidity and maternal and fetal mortality. This is a multisystemic disease, with focus on vascular dysfunction and is closely related to the exacerbated activation of the immune system. In addition to increased activation of monocytes and granulocytes, there is an elevated production of proinflammatory cytokines in pregnant women with PE. The nuclear transcription factor-kB (NF-kB) is present in the cells of the immune system and is responsible for transcription of genes related to inflammation. Whereas the PE is associated with intense inflammatory response, the use of substances modulating the activity of NF-kB factor could be useful in alleviating the inflammation present in these patients. Silibinin is the main component of silymarin, a polyphenolic extract obtained from fruits and seeds of Sylibum marianum with potent hepatoprotective, anti-inflammatory and anti-fibrotic activities. The silibinin mechanism of action includes the ability to inhibit NF-kB activation and, consequently, its migration to the nucleus. The objective of this study was to assess whether silibinin modulates the activity of NF-kB and the production of inflammatory cytokines in mononuclear cells of patients with PE. We evaluated 34 pregnant women with PE, 20 normotensive pregnant women (GN) and 15 non-pregnant women (NG). Peripheral blood mononuclear cells (PBMC) were obtained from those groups of women and cultured in the presence or absence of silibinin (5 uM or 50 uM) and stimulated or not with lipopolysaccharide (LPS) for 18 h to obtain supernatant for determination of tumor necrosis factor-alpha (TNF-α) and interleukin-1 (IL-1β) by enzyme immunoassay (ELISA). The cells were...(Complete abstract click electronic access below)

Utilização da acupuntura no tratamento de cães com discopatia intervertebral

The intervertebral disc diseases have a high casuistic in clinical routines veterinary among dogs. These conditions can cause pain, paresis or paralysis of limbs depending on the degree of injury. Clinical signs are not limited to the intervertebral disc, other anatomical parts are included. In conventional medicine, treatment may be surgical or clinical, by the use of corticosteroids with muscle relaxants. Acupuncture was an alternative to treating these diseases due to its anti-inflammatory and analgesic effects. Although there are few studies for the treatment of discopathies, acupuncture triggers the release of substances such as dynorphins, beta-endorphins and serotonin, among others; that act inhibiting somatic and visceral pain. Electroacupuncture is used to potentiate the effects of acupuncture. It can be performed with different frequencies according to the clinical evolution. However there are different opinions related to the greater efficacy in relation to acupuncture. The restraint and monitoring of the treated animal are important factors for its recovery. The association between acupuncture and conventional treatment (surgical or clinical) achieved better results than acupuncture alone. This proves that acupuncture can be considered an option in order to minimize the complications of surgery or assist in patient recovery

Bases Científicas da Acupuntura

Acupuncture is a technique belonging to traditional Chinese medicine that has existed for over 3000 years. It consists of stimuli by pressure, needling, heat and electrical stimulation of the skin at specific points to restore the health of patients. This technique has been increasingly incorporated into the West and therefore the research explaining its various mechanisms become very important to translate these ancient skills. This article is a literature review summarizing the basic concepts, historical and local, anti-inflammatory and neurological effects acupuncture in the body

Doenças osteoarticulares em pequenos animais

Osteoarticular diseases are very frequent in small animals, especially dogs. Osteoarthritis is the most common degenerative arthropathy in cats and dogs. It is one of the most important skeletal disease in small animals and it is divided into two broad classes: secondary and genetics. The secondary is originated from situations that can cause joint instability like as trauma, ligament problems and obesity among others. The gene for osteoarthritis comes from hereditary problems such as hip dysplasia, elbow dysplasia and other diseases that can cause articular instability. The hereditary osteoarticular diseases are important only because they can result in the osteoarthritis. It is important to prevent the joint instability and consequently the clinical signs that affect the quality of life of the animals. The most common clinical signs are intermittent claudication, a decrease in performance, reluctance to jump and climb ladders among others. To prevent the clinical signs or mitigate them, the treatments need to be focused on pain control and especially restoration of the affected joint. The treatments most used are the medical and surgery. Anti-inflammatory and analgesics are used in large scale for pain control and to inhibit inflammatory mediators. Furthermore, medical treatment includes weight reduction, physiotherapy and proper nutrition along with anti-inflammatory and analgesics. Surgical treatments are indicated if there is an inadequate response to medical treatment. Physiotherapy is often used in conjunction with other treatments. Besides the reduction of weight is essential and obesity is unacceptable. Cats also suffer from osteoarthritis, but the diagnosis is rarer than in dogs. Usually the cat’s owners relate the reluctance to jump and drop in performance with senility, and when the disease is diagnosed is already in... (Complete abstract click electronic access below)

Stability at different temperatures of turmeric oleoresin encapsulated in maltodextrin/gelatin matrices by freeze-drying

Turmeric (Curcuma longa L.), which has been used for long time as a spice, food preservative and coloring agent, is a rich source of beneficial phenolic compounds identified as curcuminoids. These phenolic compounds are known for their antioxidant, anti-inflammatory and antimutagenic properties, among others. On the other hand, they are very susceptible to oxidation, requiring protection against oxygen, light and heat. This protection can be achieved by microencapsulation. In this work, the characteristics and the stability of turmeric oleoresin encapsulated by freeze-drying using mixtures of maltodextrin and gelatin as wall materials were studied. Encapsulated turmeric oleoresin was stored at –20, 25 and 60 °C, in the absence of light, and analyzed over a period of 35 days for curcumin and total phenolic contents and color. Results showed that the samples produced with 26% maltodextrin/0.6% gelatin and 22% maltodextrin/3% gelatin presented good encapsulation efficiencies and solubility. In general, the method of encapsulation employed originated products with satisfactory thermal stability, although the encapsulated materials with a higher proportion of maltodextrin in relation to gelatin had better stabilities, especially at –20 and 25 °C temperatures.

Magnetically drivable nano-bio-conjugate mimicking free curcumin redox behavior

Curcumin possesses wide-ranging anti-inflammatory and anti-cancer properties and its biological activity can be correlated to its potent antioxidant capacity. Novel maghemite (gamma-Fe3O4) nanoparticles, characterized by a diameter of about 10 nm and possessing peculiar colloidal properties and surface interactions, called Surface Active Maghemite Nanoparticles (SAMN), were superficially modified with curcumin by simple incubation, due to the presence of under-coordinated Fe(III) atoms on nanoparticle surface. The resulting curcumin-modified SAMNs (SAMN@curcumin) were characterized by transmission electron microscopy (TEM), FTIR, Mossbauer, EPR and UV-Vis spectroscopy. The redox properties of bound curcumin were tested by electrochemistry. Finally, SAMN@curcumin was studied in the presence of different electroactive substances, namely hydroquinone, NADH and ferrocyanide, in order to assess its electrochemical behavior. Moreover, SAMN@curcumin was electrochemically tested in the presence of one of the most diffuse reactive oxygen specie, such as hydrogen peroxide, demonstrating its stability. SAMN@curcumin in which curcumin is firmly bound, but still retaining its redox features represents a feasible adduct: a magnetically drivable nano-bio-conjugate mimicking free Curcumin redox behavior. The proposed nanostructured material could be exploited as magnetic drivable curcumin vehicle for biomedical applications.

The therapeutic potential of exercise to treat cachexia

To discuss the role of physical exercise in the attenuation of cancer cachexia-associated symptoms, and upon the outcome of chemotherapy, with special focus on the anti-inflammatory role of chronic exercise. The review addresses the recent findings regarding the positive effects of endurance and strength exercise training upon metabolic dysfunction, systemic inflammation and body composition alterations in the syndrome of cachexia. The employment of different exercise protocol strategies, in respect to intensity, duration, work load and in concomitance with pharmacological treatment is considered. Cachexia is a multifactorial wasting syndrome afflicting patients with cancer, chronic obstructive pulmonary disease, chronic heart failure, trauma, among other diseases. This condition markedly compromises the quality of life, treatment outcome and survival. Recent literature indicates an unequivocal role of chronic exercise in modulating cachexia and other cancer-associated dysfunctions. Exercise is proposed as a complementary treatment in cancer, and represents a function-preserving, anti-inflammatory and metabolism-modulating strategy with low cost, and high versatility and availability. Furthermore, exercise decreases cancer recurrence and presents a positive impact on public health management, reducing hospitalization and medication costs.
