Welcome to Lee Lab !

Thank you for visiting our web page!

@Already 19 years have passed since this campus opened in April 2001 at Hibikino. One year before that, in 2000, I was working at the installation office for the establishment of the Faculty of Engineering (University of Kitakyushu) on the sixth floor of the International Conference Hall in Kokura. Thus, my activity in this campus actually have reached 20 years, which feel like it passed really fast. Some of them, who worked together at that time, have already retired and I have also become middle-aged.

@Although there were not so many students since I had opened Lee Laboratory in 2001, fortunately, I was able to come to the present without interrupting research. I would like to thank all the graduates and researchers who had spent a lot of time in the laboratory, although they all have gone to their own lives. Compared to 19 years ago, our research has apparently been extended to several areas, but I figure there is still plenty of work to do to achieve our goals.

@Recently, our research that has investigated a relationship between disease and odor found a very interesting result, which can be used to non-invasively diagnose oral cancer from volatile organic metabolites excreted from saliva through the collaboration with Kyushu Dental University. For the first time in the world, we have demonstrated that the identified salivary volatile organic compounds can be divided into three groups, named such as "newly produced", "increased or decreased", and "disappeared", respectively, which are changed according to the progression of cancer. We analyzed saliva samples from 12 cancer patients and 8 healthy people, and succeeded in determining the presence or absence of cancer with a probability of more than 90%. The outcome of this study is that "odor information" of oral cancer has been elucidated, but it is likely that the same method also can be applied to the diagnosis of other cancers such as lung cancer and gastric cancer. We eventually aim to establish it as a new cancer diagnostic technology, including the development of sensing devices that can diagnose cancer just by blowing our breath. We look forward to your continious interest in Lee Lab.
