Tri-phasic fever in dengue fever.

Dengue fever is an acute febrile illness with a duration of 2-12 days. Our observational study observed the 24-h continuous tympanic temperature pattern of 15 patients with dengue fever and compared this with 26 others with fever due to a non-dengue aetiology. A tri-phasic fever pattern was seen among two-thirds of dengue fever patients, but in only one with an inflammatory disease.

Evaluation of potential antiamnesic activities of aqueous extract of Vitex trifolia leaves against scopolamine induced amnesia and in normal rats.

Background: The goal of this study was to evaluate the cerebroprotective and cognition-enhancing activities of the aqueous Vitex trifolia (Vt) L. (Verbenaceae) leaf extract against scopolamine-induced amnesia and in normal rats.

Methods: Reference or working memory and long-term memory in rodents were tested by experimental paradigms like passive avoidance (PA) and T-maze (TM), respectively.
