Abstract:

Asparagus racemosus Willd. (Family Liliaceae), also known as female reproductive tonic, is traditionally used across the Sub-Himalayan region in Uttarakhand, India for treatment of epilepsy and disorders of female reproductive system. Therefore, in this study, we investigated the anticonvulsant effect of A. racemosus in a mouse model of catamenial epilepsy. We artificially increased progesterone and neurosteroid levels (a state of pseudo-pregnancy) in adult Swiss albino female mice by injecting pregnant mares' serum gonadotropin (PMSG) (5 IU s.c.), followed by human chorionic gonadotropin (HCG) (5 IU s.c.) after 46 h. In the following 10 days, A. racemosus treatment was given along with measurement of progesterone, estradiol, and corticosterone levels in the blood. Neurosteroid withdrawal was induced by finasteride (50 mg/kg,i.p.) on treatment day 9. Twenty-four hours after finasteride administration (day 10 of treatment), seizure susceptibility was evaluated with the sub-convulsant pentylenetetrazole (PTZ) dose (40 mg/kg i.p.). Four hours after PTZ, animals were assessed for depression like phenotypes followed by euthanasia and separation of brain parts (cortex and hippocampus). The results showed that PMSG and HCG treatment elevated progesterone and estradiol levels. Treatment with finasteride increased seizure susceptibility and depression due to decreased progesterone and elevated estrogen levels coupled with decreased monoamine and elevated corticosterone levels. A. racemosus treatment, on the other hand, significantly decreased seizure susceptibility and depression like behaviors, possibly because of increased progesterone, restored estradiol, corticosterone, and monoamine levels. We concluded that herbal formulations using A. racemosus root extracts may be used as monotherapy or adjuvant therapy along with available AEDs for the better and safe management of catamenial epilepsy as well as comorbid depression.
