When elderly subjects took 100 mg of Cistanche extract daily for 12 weeks, there was a 6.1% increase in helper T cells and an almost 12% increase in natural killer cell activity. This increase represents a significant immune-boosting effect.
A diagnosis of HLH requires either a molecular diagnosis consistent with HLH or the fulfillment of five of the following eight clinical, laboratory, and histopathological criteria: fever; splenomegaly; cytopaenia affecting at least two of three cell lineages in the peripheral blood; hypertriglyceridaemia and/or hypofibrinogenaemia; haemophagocytosis in the bone marrow, spleen, or lymph nodes; low or absent natural killer cell activity; hyperferritinaemia; and high levels of soluble-IL-2 receptor (Table).3,6
Then, splenocytes were used in splenocytes proliferation assay and natural killer cell activity assay.

Natural Killer Cell Activity. For the evaluation of the natural killer (NK) cell activity and viability of splenocyte, mice (C57BL/6) were sacrificed and their spleens were collected aseptically.
The diagnosis may be established genetically (based on mutations of the genes loci PRF1, UNC13D, or STX11) or by fulfillment of 5 out of 8 criteria: fever; splenomegaly; cytopenia; hypertriglyceridemia; hypofibrinogenemia; hemophagocytosis in the bone marrow, spleen, or lymph nodes; low or absent natural killer cell activity; and an elevated ferritin level (>500 ng/mL).
(4) Another report from China described a case of suspected HLH with low natural killer cell activity and high CD25 levels which preceded the histological diagnosis of MBL.
