Heart Rate Variability (HRV), a measure of parasympathetic regulation of cardiac activity, has been associated with the capacity to regulate autonomic arousal.

This study aimed to evaluate the antihyperglycemic and antioxidant activities of the lectin isolated from (BTL). Diabetes was induced in Wistar rats through low-dose streptozotocin injections. Following the confirmation of hyperglycaemia, the animals were treated with 150 mM NaCl, glibenclamide, or BTL at 600 or 900 mg/kg.
