A ultra-sonografia do pâncreas é eficaz em diagnosticar o diabete melito tipo 1 e tipo 2?

Este trabalho foi realizado para verificar se a ultra-sonografia do pâncreas oferece dados auxiliares na classificação de diabéticos adultos dos tipos 1 e 2. O tamanho e a ecogenicidade do pâncreas foram determinados pela ultra-sonografia em 81 diabéticos, sendo 20 do tipo 1 e 61 do tipo 2 (53 obesos e oito não-obesos). Os pacientes tipo 2 obesos diferiram dos demais por apresentarem área total e diâmetro ântero-posterior do corpo do pâncreas significativamente maiores. Quanto à ecogenicidade pancreática, esta estava aumentada com maior freqüência nos diabéticos tipo 2 obesos que nos diabéticos tipo 1. Consideramos, assim, que a ultra-sonografia do pâncreas constitui metodologia auxiliar na classificação de diabéticos entre os tipo 1 e 2, sendo menos eficaz quando os últimos não são obesos.

Herpes Virus Bovino tipo 1 (BoHV-1) como posible causa de encefalitis en bovinos de la región del Magdalena Medio Colombiano. Estudio serológico y análisis epidemiológico

The bovine Herpesvirus type 1 and type 5 (BoHV-1 and BoHV-5), causing diseases and significant economic losses in farms of worldwide. Both affect the nervous system of cattle, although BoHV-5 has been the most associated with this type of pathogenesis. Given the death of animals with nervous symptoms and negative diagnoses for rabies virus in the area of study, this research focused on the detection of positive reactors to bovine herpes virus serum neutralization. We collected 518 blood samples from animals without Herpesvirus vaccine, in the municipalities of Caparrapi, Cimitarra, Honda and Victoria, in the Middle Magdalena River Region. In addition, epidemiological information useful to discuss neurological disease was collected through primary and secondary sources. For the analysis of data was used chi-square test by identification of relationship between evidence of viral infection and the variables recorded. The results revealed that 286 cases were positive for Herpesvirus infection, corresponding to a prevalence of 55.5%, however, there was no statistical relationship (p < 0.05) between the presence of antibodies and the variables analyzed. In conclusion, some cases of neurological disease in cattle in this region could be due to infection with herpes viruses. We discussed about the presence of BoHV-1 and BoHV-5 in the ambient, diagnosis and monitoring plans, as well as economic losses, which may cause in herds in this area.

Analise citotoxica de esparfloxacino e seus produtos de degradaçao em células mononucleares humanas

Sparfloxacin, a difluorquinolone derivative, is a potent antibacterial agent active against a wide range of gram-positive and gram-negative organisms including Streptococcus pneumoniae, Staphylococcus aureus, methicillin resistant S. aureus, Legionella spp, Mycoplasma spp; Chlamydia spp. and Mycobacteria. A drawback of fluorquinolones is their photoreactivity. Sparfloxacin has been studied in terms of therapeutic activities. However, few reports about analytical methods of sparfloxacin are available in the literature. The aim of this study was to determine cytotoxic effects, using sparfloxacin reference substance (SPAX-SR), sparfloxacin tablets (SPAX-COMP) and sparfloxacin tablets submitted UV light during 36 hours (SPAX-COMP.36) solution, and two isolated products (7 and 9) of SPAX-SR submitted UV-C light, in concentrations of 31.25, 62.5, 125 and 250 μg/mL by in vitro mononuclear humane culture cells. The results, statistically analyzed by Teste de Tukey, showed SPAX, SPAX-COMP and SPAX-COMP.36 solutions could reduce the cells number in these conditions. These results could not be observed for products 7 or 9. These results can suggest that isolated product can be less cytotoxic than SPAX-SR, is method can also be used to identified products degradation of sparfloxacin in stability study. However, the low activity achieved with sparfloxacin submitted to UV-light is a source of concern and requires further investigation about its photodegradation mechanism.

Insulina pancreática de ratos diabéticos tipo 1 submetidos a um protocolo de treinamento físico individualizado

Since diabetes mellitus is considered a world public health problem, the present study aimed to evaluate oral glucose tolerance (TTGo) and pancreatic insulin concentration (PIC) of type I diabetic rats subjected to an individualized exercise training protocol. A total of 40 adult Wistar rats were used, half of which induced to diabetes by alloxan (32 mg/kg) endovenous injection, and divided into four groups (10 per group): Sedentary Control (SC), Trained Control (TC), Sedentary Diabetic (SD) and Trained Diabetic (TD). The physical training consisted of swimming, 1 h/day, 5 days/week during 8 weeks, supporting overload equivalent to 90% of the individual anaerobic/aerobic metabolic transition determined at the beginning of the experiment. The rats of SD and TD groups presented body weight reduction in relation to controls, which was less accentuated in TD group. Water and food ingestion increased in the diabetic groups in relation to controls. The areas under the serum glucose curve during the GTTo of diabetic groups were higher than the controls. Physical training attenuated this elevation. The diabetic groups showed reduced PIC when compared to both control groups. The physical training protocol employed improved glucose homeostasis and attenuated the body weight loss of diabetic animals but did not alter pancreatic insulin concentration. © FTCD/FIP-MOC.

Avaliação sorológica de Parainfluenzavirus Tipo 1, Salmonella spp., Mycoplasma spp. e Toxoplasma gondii em aves silvestres

Newcastle disease, salmonellosis and mycoplamosis are the most important infectious diseases in poultry. Toxoplamosis is a common disease in urban environment. The present study investigated serologic evidence of these diseases in captive and wildlife birds, with rapid plate agglutination test, haemagglutination inhibition test, and modified agglutination test. In a total of 117 blood serum samples, 20 showed the presence of Toxoplasma gondii, Mycoplasma gallisepticum, and Salmonella spp. antibodies. Amazona aestiva was the specie with the highest number of positive individuals (13/20). We also verified the first detection of T. gondii antibodies in birds of prey from Mivalgo chimachima and Rupornis magnirostris species.
