Bottom Line: Forth group, as sham, was injected saline from GD1-14, and finally control which was received neither MA nor saline.Fetus body weight and crown-rump length showed significant decrease in third compared to first and second groups (p≤0.001).There were significant differences in head circumference in control and sham compared to third group (0.5 (0.5-0.6), 0.6 (0.5-0.8), 0.4 (0.4-0.5) cm respectively, p≤0.001).

ABSTRACT

Background: Methamphetamine (MA) is one of most common illicit drugs which were reported that nearly half of MA consumers are women. MA can cross through placenta and affects pregnancy and fetus development.

Objective: Our aim was to evaluate effects of injected MA on crown-rump length, head and placental circumference, body weight, histological changes and apoptosis in fetus.

Materials and methods: Twenty-four NMRI pregnant mice were randomly divided into five groups. First, second and third groups were injected intraperitoneally 10 mg/kg/day MA during gestational days (GD): GD1-7, GD8-14, and GD1-14, respectively. Forth group, as sham, was injected saline from GD1-14, and finally control which was received neither MA nor saline. On GD15 cervical dislocated pregnant mice, fetus and placenta were weighed and fetus crown-rump length was measured. Hematoxylin and Eosin staining and TUNEL assay were applied to assess histological changes and apoptosis respectively.

Results: Fetus body weight and crown-rump length showed significant decrease in third compared to first and second groups (p≤0.001). There were significant differences in head circumference in control and sham compared to third group (0.5 (0.5-0.6), 0.6 (0.5-0.8), 0.4 (0.4-0.5) cm respectively, p≤0.001). Also fetus that treated with MA showed lower placenta circumference compared to control and sham groups. Histological changes such as exencephaly, hemorrhage and immature fetus were observed in second and third groups. Apoptotic cells in second and third groups were higher than controls, but differences were not significant.

Conclusion: It seems MA abuse during pregnancy can cause morphological and histological changes in mice fetus but the exact mechanism remains unclear.

Abortion rate in groups; there is no significant different in treated groups compared to control and sham groups (first, second and third groups were injected 10mg/kg/day of MA respectively, from GD1 to GD7, GD8 to GD14 and GD1 to GD14).

Figure 2: Abortion rate in groups; there is no significant different in treated groups compared to control and sham groups (first, second and third groups were injected 10mg/kg/day of MA respectively, from GD1 to GD7, GD8 to GD14 and GD1 to GD14).

Mentions: The data showed that different rates of abortion were gained in all groups, but the differences were insignificant (Figure 2). Birth was also observed in treated, control and sham groups, but there was pointless difference when it was compared between groups (Figure 3).
