Endometriotic implants were induced surgically in female Wistar albino rats, which were randomly divided into three groups. The rats in group I (n=10) and group II (n=9) were given 2.5 mg/kg/day intraperitoneal and oral atorvastatin, respectively, for 28 days. Group III (n=9) was given no medication (control). The mean volume and weight of explants in group I were significantly lower (both P < 0.05) compared with group III. Histopathological score of the implants was significantly lower in groups I and II, when compared with group III (P < 0.01 and P < 0.05, respectively). There were significant reductions in explant concentrations of vascular endothelial growth factor and matrix metalloproteinase 9 in group I (P < 0.01 and P < 0.001, respectively) and group II (both P < 0.01) compared with group III while staining due to tissue inhibitor of metalloproteinase 2 was significantly higher in group I (P < 0.01) and group II (P < 0.01) compared with group III. Moreover, explant concentration of superoxide dismutase was significantly increased in groups I and II compared with group III (both P < 0.05). In conclusion, atorvastatin causes significant regression of endometriotic implants in rats. Moreover, intraperitoneal atorvastatin seems to be more effective than oral atorvastatin.

Elevated level of hs-CRP is a useful parameter in the severity of clinical risk of pre-eclampsia in patients with BMI < 25 kg/m(2) at third trimester.

This study has shown that maternal vitamin D deficiency is related with an increased risk of SGA delivery. Further studies are needed to explain the relationship with vitamin D deficiency and poor perinatal outcomes.

Melatonin induces the regression of endometriotic implants in rats by modulating implant levels of SOD, MDA, VEGF, MMP-9 and TIMP-2.
