Colloidal lanthanum as a marker exists in extracellular space and does not crossthe intact plasma membrane in normal condition.Consequently,it may be used todemonstrate the change of plasma membrane permeability at cellular level.Theabdominal aorta was constricted in 33 rats for 10 days,so as to establish a modelof myocardial hypertrophy.The outer and inner layers of left ventricle wall of theheart were removed and fixed immediately in 2% glutaraldehyde and 0.1 M cacody-late buffer(pH 7.4)containing 1% La(NO_3)_3 for 3 hours.In normal control tissuethe lanthanum tracer was confined to the extracellular space,basement membraneand intercalated disc.In inner layer of left ventricular wall of the experimental group,the lanthanum was deposited on the outer membrane of the mitochondria.In somemyocytes of the outer layer of left ventricular wall,their structure appearedmorphologically normal,but intracellular lanthanum appeared.Thus lanthanum canbe used as a sensitive indicator of membrane permeability in early stage of themyocardial hypertrophy.

Chronic obstructive pneumonia cancer transformation refers to the malignant transformation of long-term repeated chronic inflammation of the lung. Traditional Chinese Medicine believes that the etiology and pathogenesis of chronic obstructive pneumonia cancer transformation always belong to the deficiency of origin and excess of signs. Chronic obstructive pulmonary disease causes damage to the qi of the lung, spleen and kidney. Qi is yang, and qi deficiency leads to yang deficiency. Yang deficiency and abnormal warm would result in qi stagnation, phlegm coagulation and blood stasis. It is the key to the transformation of chronic obstructive pneumonia cancer. Kidney yang is the root of yang qi. Deficiency of kidney yang is the initiating factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of lung yang is the fundamental factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of kidney yang and deficiency of spleen yang are the driving factors for the transformation of chronic obstructive pneumonia cancer. Therefore, this article discussed the role of kidney yang in the transformation of chronic obstructive pneumonia cancer from the theory of "Qi Zhu Xu Zhi", in order to broaden the thinking of clinical diagnosis and treatment of the disease.
