Abstract

Hypoxia as one of the most common clinical disturbances in pregnancy period can cause destructive changes in motor sensory cortex and can lead to imperfect organization in motor reactions. Crocin, a water-soluble carotenoid, is the most active ingredients of saffron and a lot of studies declare its positive effectiveness on improving motor activity. Since the hypoxia intensity affects its malicious amount on movement, in this paper, we have studied the effect of crocin in three maternal hypoxia protocols with different oxygen intensities on motor activity and balance in rat offspring. In this experiment, female rats (Wistar) were used on the 20th day of pregnancy. The rats were randomly divided into eight experimental groups: sham, crocin, hypoxia with three different intensities: 10% oxygen and 90% nitrogen for 1 h (hypoxia-ɪ), 7% oxygen and 93% nitrogen for 1 h (hypoxia-ɪɪ), 7% oxygen and 93% nitrogen for 3 h (hypoxia-ɪɪɪ) and treated-crocin hypoxia groups. To produce hypoxia, pregnant rats were placed in a hypoxia box. In crocin group, rat offspring received 30 mg/kg crocin via IP injection at P14–28. Control group also received saline injection at the same time. Finally, balance and motor activity in offspring were measured respectively by rotarod and open-field devices. Results showed that motor activity significantly decreased in hypoxia-ɪɪɪ group as compared with sham group (p < 0.01). Balance in hypoxia-ɪɪɪ group significantly decreased as compared with sham group (p < 0.05). As a result, crocin treatment improved all these changes. The results of this study implied that both hypoxia duration and intensity have profound effects on motor activities impairments.
