Transport of amino acids from milk whey by Caco-2 cell monolayer after hydrolytic action of gastrointestinal enzymes

The bioavailability of amino adds from milk whey protein hydrolysates was evaluated using diffusion of the substances through semi-permeable membranes (dialyzability) and transport by Caco-2 cell cultures. The hydrolysates with low degree of hydrolysis (LDH) and high degree of hydrolysis (HDH) were obtained after 120 min of reaction time at 50 degrees C after the initial addition of pepsin, followed by the addition of trypsin, chymotrypsin and carboxypeptidase-A. The proteins and hydrolysates were further subjected to in vitro digestion with pepsin plus pancreatin. HPLC was used to determine the concentrations of dialyzable amino adds (48.4% of the non-hydrolyzed proteins, 63.2% of the LDH sample and 58.3% of the HDH sample), demonstrating the greater dialyzability of the hydrolysates. The LDH and HDH whey protein hydrolysates prepared with pepsin, trypsin, chymotrypsin and carboxypeptidase-A showed only 14.7% and 20.8% of dialyzable small peptides and amino acids, respectively. The efficiency of absorption was demonstrated by the preferential transport of Ile, Lou and Arg through a layer of cells. In the LDH hydrolysate, Tyr was also transported. Prior high- and low-degree hydrolysis of the whey provided transport by 5.7% and 6.6%, respectively, in comparison with 23% for non-hydrolyzed proteins, considering the total amount of these amino adds that was applied to the cells.

Carbohydrate-Dependent, Exercise-Induced Gastrointestinal Distress

Gastrointestinal (GI) problems are a common concern of athletes during intense exercise. Ultimately, these symptoms can impair performance and possibly prevent athletes from winning or even finishing a race. The main causes of GI problems during exercise are mechanical, ischemic and nutritional factors. Among the nutritional factors, a high intake of carbohydrate and hyperosmolar solutions increases GI problems. A number of nutritional manipulations have been proposed to minimize gastrointestinal symptoms, including the use of multiple transportable carbohydrates. This type of CHO intake increases the oxidation rates and can prevent the accumulation of carbohydrate in the intestine. Glucose (6%) or glucose plus fructose (8%-10%) beverages are recommended in order to increase CHO intake while avoiding the gastric emptying delay. Training the gut with high intake of CHO may increase absorption capacity and probably prevent GI distress. CHO mouth rinse may be a good strategy to enhance performance without using GI tract in exercises lasting less than an hour. Future strategies should be investigated comparing different CHO types, doses, and concentration in exercises with the same characteristics.

Tuberculose e sua importância para a pecuária brasileira

Tuberculosis due the large number of victims that come attacking in recent years has become a major concern in the World Health Organization. It is caused by a bacterium that is becoming increasingly resistant to drugs, because it requires long periods in treatment that are not always followed correctly. AIDS has contributed much in recent years with increased morbidity and mortality of Mycobacterium. The Ministry of Agriculture, Livestock and Supply (MAPA) of Brazil in 2001 created the National Program of Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT) establishing guidelines such as: sets the method to diagnose, control and certify herds free of disease. Joining the program is voluntary

Endoscopia do trato gastrointestinal de cães e gatos

Endoscopy of the gastrointestinal tract is a specialized minimally invasive diagnostic method and with both diagnostic and therapeutic possibilities. It is divided into two major groups, the rigid and flexible endoscopy. The first most widely used for visualization of body cavities that do not have a light, like the chest, for example, and the second for those with light as the gastrointestinal tract. In Brazil there are few professionals, veterinary hospitals or clinics that offer this type of service. Thus, endoscopy is an area of expertise of the veterinarian who is in huge expansion and has shown great applicability with excellent results in both clinical medicine and surgical small animals

Tratamento de tuberculose: estudo de interações farmacocinéticas da Isoniazida

O tratamento convencional da tuberculose constitui-se pela administração simultânea dos fármacos isoniazida (INH), rifampicina (RMP) e pirazinamida (PZA) durante dois meses, seguida por quatro meses da associação INH e RMP. Esta estratégia resulta em sucesso terapêutico na maioria dos casos quando existe obediência do paciente ao regime posológico. O abandono do tratamento tem sido relacionado ao longo período de exposição aos fármacos e ao aparecimento de efeitos adversos, entre eles, a hepatotoxicidade induzida por INH. O período prolongado de tratamento, seus efeitos adversos, a alta taxa de abandono do tratamento e o aparecimento de cepas resistentes aos fármacos convencionais tem estimulado a busca de novas alternativas terapêuticas para a tuberculose. Neste sentido tem sido proposto o uso da fluoroquinolona Ciprofloxacina(CIPRO) no esquema terapêutico da tuberculose, em associação com INH e RMP. Embora a associação de INH, RMP e CIPRO apresentem efeitos antibacterianos sinérgicos in vitro e supostamente seja proveitosa para o tratamento da tuberculose, sua influência sobre a hepatotoxicidade da isoniazida não é conhecida

Tratamento da tuberculose: estudo de interações farmacocinéticas da pirazinamida

Convencionalmente o tratamento da tuberculose se dá pela administração simultânea dos fármacos pirazinamida (PZA), rifampicina (RMP) e isoniazida (INH) durante dois meses, seguida por quatro meses da associação INH e RMP. A medicação é de uso diário e deve ser administrada de preferência em uma única dose em jejum ou, em caso de intolerância digestiva, junto com uma refeição. Esta estratégia resulta em sucesso terapêutico na maioria dos casos quando existe obediência do paciente ao regime posológico. O abandono ao tratamento pelo paciente tem sido relacionado ao longo período de exposição aos fármacos e ao aparecimento de efeitos adversos, entre eles, a hepatotoxicidade principalmente em pacientes geriátricos que apresentam deficiências nutricionais ou etilismo crônico. A utilização de associações medicamentosas, como no tratamento da tuberculose, pode resultar em interações farmacocinéticas. Considerando a importância do metabolismo da PZA no desenvolvimento da hepatotoxicidade, a capacidade de indução ou inibição enzimática dos fármacos e a probabilidade de interação farmacocinética entre a PZA, a INH e a RMP, é possível que esta associação resulte em diferentes perfis farmacocinéticos com conseqüente alteração de efeitos hepatotóxicos. Assim, o presente trabalho visa avaliar os efeitos da administração simultânea de INH e RMP sobre os parâmetros farmacocinéticos da PZA em um grupo de animais (coelhos albinos) sob tratamento com PZA e outro com PZA+INH+RMP bem como os níveis de biomarcadores de hepatotoxicidade – as transaminases AST e ALT – antes e após a administração de doses múltiplas destes fármacos

Brucelose e tuberculose como doenças ocupacionais em matadouros-frigoríficos de bovinos no Brasil

Tuberculosis and brucellosis are important diseases in national scenario, as they affect national cattle and can be transmitted to human, as they are zoonosis. The transmission risk increases mostly for those who have strict contact with animals, as is this case of slaughterhouse workers. This paper presents a bibliographic review of data referent to both diseases occurring in bovine slaughterhouse workers in Brazil, characterizing as occupational zoonosis diseases. We still have few data available of this subject, what raise difficulties to know the real incidence of both diseases in national cattle and in people who work in contact with animals, and most of the time are not instructed to the risk that they are exposed and how to prevent it. It’s important to know which is the situation of both diseases so that prevention and even eradication measures can be taken, as we know the Veterinary has an essential function in this matter, protecting animal health as much as protecting national public health
