ABSTRACT. Shuangren-Anshen capsule (SAC) is a traditional Chinese herb that was improved in our laboratory. An orthogonal experiment [L 9 (3) 4 ] was used to optimize the extraction conditions. In vivo, a hemorrhage mouse model was established and the hemoglobin contents of normal control, model control, and treated mice were measured. Additionally, the sedative and hypnotic effects of SACs were assessed based on pharmacological parameters such as changes in locomotive activity, forelimb raising, sleep latency, sleep duration, and number of mice that fell asleep. Brain tissue was sectioned and stained to detect 2 X.X. Liu et al. Genetics and Molecular Research 15 (3): gmr.15038806 changes in cell morphology by microscopy. The optimum extraction was achieved with 3 cycles of decoction for 120 min each with a 10-fold volume of water added. In the model control group, hemoglobin content significantly decreased and pharmacological parameters increased (P < 0.01) relative to that in the normal control group. Compared to the model control group, the group treated with 0.9 g/kg SAC showed significant (P < 0.05) increase or decrease in hemoglobin content and all pharmacological parameters except sleep duration. The groups treated with 1.8 or 3.6 g/kg SAC and the positive control group also showed significant alterations in hemoglobin content and pharmacological parameters (P < 0.05). In addition, SAC exhibited a protective effect on the morphological structures of the damaged nerve cells in the mouse model. Thus, an optimal extraction process was successfully identified. The pharmacological data also suggests that the drug can improve sleep quality. SAC treatment was shown to cause changes in hemoglobin content and cell morphology in a mouse model.
