Protective effect of HHKV extract on lymphocytes in persons with and without cancer bearing oxygenated stress in vitro

The study on blood samples of 20 cancer patients in Hanoi Cancer Hospital and 10 healthy subjects showed that peripheral blood lymphocytes of cancer patients and healthy subjects contacting with low concentration H2O2 (10-8 mol) were damaged dramatically. At the present of HHKV extract 30 mcg/ml in same condition of oxygenated stress lymphocytes were protected partly. There was a higher statistically significant difference of imfulse number in these samples in comparing with no HHKV samples. Apart from antioxidant effect, HHKV had also a stimulant effect in the transformation of lymphocytes. The responses of lymphocyte samples with PHA in healthy persons were 8894.60701.49 and in cancer patients 1890.86459.30

Lymphocytic protective effect of HHKV in elderly with oxidant stress

A study on the lymphocytic protective effect of HHKV was carried out on 20 samples of lymphocyte precipitated from peripheral blood of elderly. The lymphocytes suffered the oxidant lesion and exposure with HHKV. The results have shown that the HHKV recovered the function of lymphocytes with the oxidant lesion to normal level. These results indicated that the HHKV helped the elderly to limit the oxidant lesions for cells, which are responsible for immunoresponse and improve the ability of response to unspecific immune.
