Tamsulosin vs Naftopidil in Medical Expulsive Therapy for Ureteral Stones — A Randomized Controlled Study.

The aim of the present study was to compare the efficacy of naftopidil and tamsulosin in the management of ureteral stones. A total of 92 patients with symptomatic, single < 10 mm ureteral stone, were enrolled in a prospective study and randomized into two groups. Group 1, received 0.4 mg tamsulosin daily, whereas Group 2, received 50 mg naftopidil daily. Patients were followed –up for up to 6 weeks. The primary end point was stone expulsion rate and secondary end points were stone expulsion time , the rate of interventions such as uretero-renoscopy, ureteric stenting and extracorporeal shock wave lithotripsy and side effects. There were no significant differences between the groups with respect to age, sex, stone size and location. Stone expulsion rate were 76% and 56% in the tamsulosin and naftopidil group respectively. No significant difference in the stone expulsion time and the rate of interventions between the two groups. The finding suggest that tamsulosin is superior to naftopidil for stone expulsion therapy.

The Anticonvulsant Effect of Eupatorium Birmanicum DC Leave Extract Alone and in Combination with Phenytoin Against MES Seizure in Albino Mice.

To evaluate the anticonvulsant activity of aqueous extract of Eupatorium birmanicum DC leave (EB) alone and in combination with phenytoin against MES seizure in albino mice. Method: Aqueous extract of EB was prepared using Soxhlet apparatus. The anticonvulsant effect of the extract was tested on prescreened albino mice at 3 doses (200, 400 & 800 mg/kg). After 1 hr of oral administration of EB the animals were subjected to MES seizures by convulsiometer with a current of 45 mA for 0.2 sec via transauricular electrodes and the duration of the THLE was recorded. Sub-anticonvulsant dose of phenytoin was also determined and the effect of its combination with the most effective dose of EB tested. Results: EB aqueous extract exhibited significant anticonvulsant activity in the MES model at doses 400 mg/ kg (p<0.01) & 800 mg/kg (p<0.001). This reduction in the duration of THLE at 800mg/kg of EB was further reduced significantly (p<0.001) when combined with subanticonvulsant doses of phenytoin (10mg/kg). Conclusion: The aqueous extract of E. birmanicum leaves showed significant anticonvulsant activity in MES seizure model in albino mice and it significantly increased the anticonvulsant effect of phenytoin in the same animal model.
