Chemical Modification of the Histidine Residue in Phospholipase A, (Naja naja naja)

Reaction of phospholipase A, (Naja naja naja) with pbromophenacyl bromide leads to almost complete loss of enzymatic activity. The rate of inactivation is pa-dependent with ,pK, = 6.9 for the ionizing residue. p-Bromophenacyl bromide modifies 0.5 mol of histidinelmol of enzyme as judged by amino acid analysis and incorporation studies with W-labeled reagent. The rate of inactivation is affected...

Proteomic characterization of the thermostable toxins from Naja naja venom

Naja naja snake venom presents abundant thermostable peptides. Many of them possess useful pharmacological activity that may be employed for drug development. For the proteomic characterization of such toxins, in the present study, Naja naja venom solution was heated up to 100°C for 10, 30, 60, 120, 180 and 300 minutes and protein fractions of non-heated and heated venom were analyzed by twodim...

Immunization studies with Naja naja venom detoxified by photooxidation.

Differential Effects of Naja naja atra Venom on Immune Activity

Previous studies reported that Naja naja atra venom (NNAV) inhibited inflammation and adjuvant arthritis. Here we investigated the role of NNAV in regulation of immune responses in mice. Oral administration of NNAV to normal mice showed significant increase in natural killer cell activity, B lymphocyte proliferation stimulated by lipopolysaccharides, and antibody production in response to sheep...

In Vitro and in Vivo Neutralizing Potential of Terminalia Arjuna Bark Extract against Naja Naja Venom

Envenoming’s by snake bite to involve medical emergencies and its clinical management is by the administration of antivenom. As antivenom was reported to induce early or late adverse reactions against human beings, snake venom neutralizing potential for aqueous bark of Terminalia arjuna extract was tested for the present research by in vitro and in vivo methods against Naja naja venom. In vitro...
