title: [Effect of 5 warm-hot nature Chinese drugs for promoting blood circulation and removing blood stasis on 5-HT, NE, and endocrine hormones of rats of cold coagulation and blood stasis syndrome].
abstract: OBJECTIVE
  To study the mechanism of warm-hot nature Chinese drugs (WHNCD) for promoting blood circulation and removing blood stasis (PBCRBS) for intervening model rats of cold coagulation and blood stasis syndrome (CCBSS).
  
  
  METHODS
  CCBSS rat model was set up in outbred SD rats using ice water immersion method. Totally 300 successfully modeled CCBSS rats were randomly divided into 5 groups according to the principle of balance weight, 60 in each group. Contents of triothyrone (T3), tetraiodothyroine (T4), progesterone (P), 5-hydroxytryptamine (5-HT), and noradrenalin (NE) were paralleledly detected in all groups. Then rats in each group were subdivided into 6 subgroups as the model group, the curcuma group, the Ligsticum Chuanxiong group, the safflower group, the Rhizoma Corydalis group, and the Olibanumg group. Besides, 5 normal control groups were set up for 5 indices, 50 rats in total. We need 70 rats (7 groups) to finish observing 1 index, 350 rats in total for 5 indices. Except those in the model group and the normal control group, rats were administered with corresponding decoction at 20 g crude drugs/kg body weight by gastrogavage, 3 mL each time, once daily for 7 successive days. Equal volume of normal saline was given to rats in the normal control group and the model group. Contents of T3, T4, P, 5-HT, and NE were detected before treatment and 1 week after treatment.
  
  
  RESULTS
  Compared with before treatment in the same group, T3 increased in the Ligsticum Chuanxiong group and the Olibanumg group, 5-HT increased in the Ligsticum Chuanxiong group, T4, NE, and P increased in all medicated groups (P < 0.05). Compared with the normal control group, contents of T3, T4, 5-HT, NE, and P in the model group decreased (P < 0.05). Compared with the model group, contents of T3, T4, 5-HT, and NE increased in each medicated group (P < 0.05). There was statistical difference in contents of P between the Ligsticum Chuanxiong group and the Olibanumg group (P < 0.05).
  
  
  CONCLUSIONS
  WHNCD for PBCRBS had regulatory roles in serum contents of T3, T4, P, and NE in modeled rats of CCBSS. They could promote the thyroid gland-gonadal axis function, enhance the function of the endocrine system, which might be one of the pharmacodynamic mechanism of WHNCD for PBCRBS in intervening CCBSS.
