Effect of Nigella sativa supplementation on lung function and inflammatory mediatorsin partly controlled asthma: a randomized controlled trial.

Background: Nigella sativa and its derivatives have been reported to have anti-inflammatory and bronchodilator effects, but the effects have been evaluated in only a few clinical studies.

Objectives: To determine the effect of N sativa supplementation on inflammation of the airways and limitation of airflow in partly controlled asthma patients.

Design: Single-blind, placebo-controlled, randomized study.

Synergistic interaction of adenosine diphosphate-epinephrine and epinephrine-collagen in aggregation of human platelets.

Background: Efficient hemostasis in human body depends on a complicated series of events which actively involve blood platelets. Platelets exhibit diverse responses in a variety of agonists. In vivo, most of the agonists act in synergism, causing aggregation of platelets.
