Abstract

OBJECTIVE:

To study the effects of four kinds of traditional Chinese herbal compound, Sini powder, Banxiahoupu soup, Ganmaidazao soup and Guizhigancaolonggumuli soup, on the experimental acute stress behaviors and the hypothalamus-pituitary-adrenal gland axis.

METHOD:

Rats were divide into 7 groups:

  1. normal group,

  2. model 1 and

  3. model 2 groups,

  4. Sini powder group,

  5. Banxiahoupu soup group,

  6. Ganmaidazao soup group, and

  7. Guizhigancaolonggumuli soup group.

 

The behaviors of the rats and their CRH of the hypothalamus, ACTH of plasma and CORT of serum (by the means of radio-immunity) were detected.

 

RESULT:

 

 

Sini powder could reduce the crossing times of open-field test( P < 0.01) and the contents of CRH and CORT (P < 0.01, P < 0.05);

 

Banxiahoupu soup could extent the still time of tail-hanging test ( P < 0.05) and the content of CRH (P < 0.05);

 

Explanation by Joe Hing Kwok Chu

Cortisol (CORT)  becomes high during stress condition. Cortisol is triggered by ACTH (adrenacorticotropic hormone) secreted by the pituitary gland, which in turn is trigger by CRH (corticotropic releasing hormone) secreted by the hypothalamus.

The above path (connection) is called:

  1. hypothalamic–pituitary–adrenal axis (HPA or HTPA axis), or

  2. limbic–hypothalamic–pituitary–adrenal axis (LHPA axis) , or

  3. hypothalamic–pituitary–adrenal–gonadotropic axis
