The malignant behavior of the tumor cells are related to the changes in the structure of the membrane glycoprotein and lipid. It is said that the malignant hyperplasia of the tumor cells could be inhibited if the chains of saccharic molecule exposed on the cell-surface membrane were covered with plant lec-展开更多

Hematoporphyrin derivative （HPD） photosensitization therapy both for diagnosis and cure of solid neoplasms has been shown to be hopeful. So far some molecular mechanisms of HPD-photosensitization have been reported....Hematoporphyrin derivative （HPD） photosensitization therapy both for diagnosis and cure of solid neoplasms has been shown to be hopeful. So far some molecular mechanisms of HPD-photosensitization have been reported. A single oxygen （1O2） mechanism is generally thought to be predominar, but contributions from a free展开更多

Specifical receptor proteins, such as glycoprotein which is located in the lipid bilayers and stretches to the surface of the cell membrane take part in many important physiological activities. Those saccharous chains can specifically combine with plant lectins and produce agglutination, then the malignant展开更多
