Introduction: Visceral leishmaniasis (VL) is a disease caused by protozoa of the genus Leishmania and transmitted by sandflies. Brazil is one of the most important endemic areas for the disease, being necessary monitoring of the occurrence of the disease through active epidemiological surveillance. Adenosine deaminase (ADA) is an enzyme that catalyzes the deamination of adenosine to produce inosine and ammonia....
Introduction: Visceral leishmaniasis (VL; kala-azar) is a serious zoonosis that can be lethal, especially in untreated patients. Due to the fact that the State of Ceará is still an important area of transmission of VL, and based on the constant reports of the urbanization process of the disease in the country, it was necessary to monitor the occurrence of cases of leishmaniasis through epidemiological surveilla...
The triterpene mixture, a - and h -amyrin, isolated from Protium heptaphyllum resin was evaluated on capsaicin- evoked nociception in mice. Orally administered a - and h -amyrin (3 to 100 mg/kg) significantly suppressed the nociceptive behaviors—evoked by either subplantar (1.6 A g) or intracolonic (149 A g) application of capsaicin. The antinociception produced by a - and h -amyrin against subplantar capsaicin...
Adenosine deaminase (ADA – E.C.3.5.4.4.) is a fundamental enzyme in the catabolism of the purines. It catalyzes the deamination of adenosine or 2’deoxy-adenosine producing ammonium and inosine or 2’-deoxyinosine, respectively. Its activity is expressed by two isoenzymes presented in three isoforms. ADA1 (36 kDa) and ADA1 bound to CD26 (280kDa) are widely distributed in the body tissues. Their action is particul...
