Abstract:
ObjectiveTo explore the effect of the swimming training on the microcirculations in cochlea in guinea pigs after chronic hypoxia.Methods28 guinea pigs were divided into normal control group (group A) which were outside of cabin and chronic hypoxia model group (group B) randomly. 4 weeks after, the model group were divided into the model control group (group B1), medical treatment group (group B2) and swimming training with medical treatment group (group B3). The blood flow of the cochlea (CBF) were measured using laser Doppler flow. The spiral ligament spreaded-slice optical lens was used to observe the vascular veins, capillary appearance and red blood cells (RBC) counts.Resultsthe CBF of group A was(98.075±5.08)% ,while that of group B1 was(86.80±2.12)%(P<0.01 vs group A), that of group B2 was (89.14±4.12)%(P<0.05 vs group B1), that of group B3 was (91.18±5.02)%(P>0.05 vs group B2, but P<0.01 vs group B1).ConclusionSwimming training can facilitate the improvement of the swelling on the thin blood vessel and the microcirculation in cochlea under chronic hypoxia environment with ligustrazine in guinea pigs.
