We seek to look into changes of immune-competent cells by two commonly utilized HF, including Shi-Quan-Da-Bu-Tang (SDT) and Bu-Zong-Ye-Qi-Tang (BYT). However, the effects of both formulae on levels of leukocyte subsets are not yet defied. After administration of immno-suppressant to animals, the effects by HFs on the augmentation for subsets of leukocytes, CD positive cell counts of lymphocytes, and the cytokine-producing cells are measured. Our results show that SDT augments the level of lymphocytes, while BYT increases the level of granulocytes. In our clinical study with 15 healthy volunteers, positive cells for CD2, CD11b, CD14, IL-4, IL-1β and IFN-γ in peripheral blood are increased significantly 15 days after the ingestion of HFs. In rodents, compromised host as well as normal animal is administered with cancer chemotherapeutic agent (Mytomycin-C). Our observations show that SDT regulates phagocyte activities of the immune system, introducing it against intracellular parasite, and that BYT augments intercellular pathogen through humoral immunity. We discuss the significance and mechanism of HFs on the level of leukocyte subsets in number and function that are considered to be potential indicators for the evaluation of TCM modalities. We also propose an idea that TCM exhibits tonic effects via enhancing the ability to fight against infection and bacteria, as well as turning the multi-drug resistant bacteria to the sensitive ones. Together with these evidences, we suggest an ideal remedy for the compromised to fight host against pathogens. Moreover, we try to modify these hemopoietic formulae to more digestive forms. This modification brings to the significant lifted up for antibody producing cells and anti-oxidative activity for phagocytic cells.展开更多

Cardiotoxicity is uncommon but life-threatening manifestations such as myocardial infarction may manifest owing to 5-FU-induced coronary artery spasm. Administering smaller doses of the drug, more frequently than not, decreases the risk of cardiotoxicity compared to large doses or with continuous infusions. We present a case of ST-segment elevation in a patient without known coronary artery disease who had presented following continuous 5-FU infusion. Coronary angiogram confirmed absence of coronary artery disease and intravenous calcium channel blockers administration was commensurate with the patient’s improvement in symptoms. We discuss the literature on 5-FU and its association with coronary artery spasm, and also briefly review chemotherapy-induced cardiotoxicities to help better prepare internists and other primary health care providers to face similar challenges, particularly of the uncommon but potentially life-threatening manifestations.展开更多
