Chinese Herbal Medicine Alleviates Thyroidectomy-Induced Cardiopulmonary Exercise Dysfunction in Rats

Figure 4

Oral treatment with the herbal formula B307 (CHM) effectively improved neck subcutaneous blood flow and cardiac ejection function in TD rats. (a) Neck subcutaneous microcirculatory flow imaging among sham, CHM, TD, and TD + CHM rats by using moorFLPI laser Doppler imager. Neck subcutaneous blood flow of sham rats with CHM treatment were markedly greater than those sham rats without CHM treatment. While neck subcutaneous blood flow of TD rats with CHM treatment were markedly greater than those TD rats without CHM treatment. (b-c) Statistical comparison of quantified neck subcutaneous blood flow and cardiac ejection function among sham, CHM, TD, and TD + CHM rats. Neck subcutaneous blood flow and cardiac ejection function of TD rats were significantly lower than those of sham rats but significantly higher in TD + CHM rats than in sham rates. The results are shown as mean ± SEM (, , N = 5 for each group, two-way ANOVA followed by Student–Newman–Keuls multiple comparison posttest).
