[Pharmacological studies on erzhi pills]

Area of Science:

• Immunopharmacology
• Traditional Chinese Medicine

Background:

• Prednisolone can suppress immune function.
• Carbon tetrachloride (CCl4) is a known hepatotoxin.
• Assessing the immunomodulatory effects of herbal medicines is crucial.

Purpose of the Study:

• To investigate the immunomodulatory effects of Erzhi Pills.
• To evaluate the protective effects of Erzhi Pills against prednisolone-induced immunosuppression and CCl4 intoxication.
• To compare the efficacy of Erzhi Pills with Steamed Ligustrum lucidum.

Main Methods:

• Mice were treated with Erzhi Pills and/or prednisolone.
• Immunological organ weights were measured.
• Specific immune responses including sheep red blood cell antibody (SRID) precipitation, plaque-forming cell (PFC) hemolytic activity, and carbon clearance rates were assessed.
• Hepatoprotective effects against CCl4 were evaluated.

Main Results:

• Erzhi Pills significantly increased the weights of immunological organs.
• The pills counteracted the immunosuppressive effects of prednisolone.
• Erzhi Pills enhanced SRID precipitation, PFC hemolytic activity, and carbon clearance.
• Erzhi Pills demonstrated protection against CCl4-induced liver injury.
• Steamed Ligustrum lucidum exhibited comparable effects to Erzhi Pills.

Conclusions:

• Erzhi Pills possess significant immunomodulatory and hepatoprotective properties.
• Erzhi Pills can mitigate drug-induced immunosuppression.
• Steamed Ligustrum lucidum shares similar therapeutic actions with Erzhi Pills, suggesting potential synergistic or shared active components.
