During my graduate school years at University of Kansas, I worked mainly on acid-base balance, especially on the estimation of intracellular pH. Subsequently, I went to Mayo Clinic and Mayo Foundation as a post-doctor, my major research work was involved with respiratory function. Since then, my research activity was mainly focused on respiratory physiology. However, during early period of 1990s, I was involved with a group of investigators at University of Kentucky (also at NTU) working on the problem related to pulmonary hypertension. Accordingly, I continued these two fields (respiratory function and pulmonary hypertension) of research work until my retirement at NTU Medical Center, July of 2003. After my retirement, in addition to the adjount appointment at NTU Medical Center, I have served as a consultant at MDS Pharma Services in Peitou, Taipei. My main responsibility at MDS is to check or to edit reports prior to their delivery to clients. In addition, I help to develop projects related to respiratory field required by customers.

  1. Before my retirement (August of 2003), the respiration physiology laboratory had focused work related to function of the lungs. The main research includes following two topics:
    Lung and airway function. For more than a decade, we have used physiological and pharmacological methods to investigate the relationship between airway/lung function and noncholinergic nervous system. Previously, it is known that there are two (sympathetic and parasympathetic) systems which innervate the lungs. About 10-20 years ago, researchers found another (noncholinergic) system which belongs to neither sympathetic nor parasympathetic system. This new nervous system is easily activated by capsaicin and releases tachykinins (mainly substance P and neurokinin A). In the lungs, tachykinins cause increases in secretion, vascular extravasation (edema), and airway constriction. In my laboratory, we are focused on effects of tachykinins on airway constriction. In this aspect, this type of research may be associated with asthma since breathing difficulty in asthmatic patients is usually caused by airway constriction. We have employed antioxidants and tetrodotoxin to prevent or attenuate airway constriction caused by the activation of noncholinergic system. Thus, oxygen radicals and axon reflex play an important role in noncholinergic airway constriction.
  2. Pulmonary hypertension. We employed two methods to induce pulmonary hypertension in experimental animals: monocrotaline and chronic hypoxia. Monocrotaline is purified from the extract of a plant (Crotalaria spetabilis) and induces pulmonary hypertension about three weeks following subcutaneous injection. Two weeks of hypoxic exposure causes also pulmonary hypertension. This is because both monocrotaline and chronic hypoxia induce augmented proliferation of smooth muscle and connective tissues on the pulmonary vascular wall. Thickening of the vascular wall causes a decrease in luminal dimension and an increase in pulmonary arterial pressure (pulmonary hypertension). When tachykinins was depleted by capsaicin pretreatment, pulmonary hypertension induced by monocrotaline or chronic hypoxia was significantly attenuated. Thus, we suggest that tachykinins play an important role in the development of pulmonary hypertension.
