New Perspectives of HIV/AIDS Therapy Study.

HIV/AIDS (acquired immune deficient syndrome), a human infectious disease was once listed as the No. 1 disease killer in US (1993). After the invention of antiviral drug cocktails-high active anti-retroviral therapy (HAART), most HIV-infected patients can survive much longer than with single antiviral drugs or vaccines alone.

Absorption, distribution and excretion of ¹⁴C-probimane in mice bearing lewis lung carcinoma.

Spontaneous neoplasm metastasis, a fatalist pathological feature of cancer, is a long-evolving, multi-steps process that can now only be treated or controlled by drugs or immuno-modulators. Probimane (Pro), as a representative of the well-known class of antimetastatic agents âBisdioxopiperazine compounds (Biz)â, is systematically studied for its absorption, distribution and excretion in mice bearing Lewis lung carcinoma by a radioactivity-detective method in this investigation. It is found that the (14)C-Pro concentrations in different normal organs of mice at 2 hrs are very high and dramatically declined at 24 and 48 hrs.

Different spontaneous pulmonary metastasis inhibitions against lewis lung carcinoma in mice by bisdioxopiperazine compounds of different treatment schedules.

Spontaneous neoplasm metastasis, a fatalist pathological feature of cancer, is a long-evolving, multi-steps process that can now only be treated or controlled by drugs or immuno-modulators. As we have previously hypothesized, each drug or immuno-modulator might act differently within various stages of a metastasis. Therefore any researches helping to determine these differences will be beneficial for updating therapeutics for metastasis.
