Gmel(H. abyssinica) flower. Methods: Mice were infected with(150 ± 10) Schistosoma mansoni cercariae by paddling technique. Crude extracts were administered orally for five consecutive days at doses of 300, 600 and 1 200 mg/kg/day along with 200 mg/kg/day praziquantel and 3% tween 80 given as a control. Results: E. kebericho root extract showed a statistically significant(P < 0.05) reduction in fecal egg count of 64.44%, 42.96% & 26.82% and worm burden of 65.71%, 47.86% & 31.43% at treatment doses of 1 200 mg/kg/day, 600 mg/kg/day and 300 mg/kg/day, respectively. Similarly, H. abyssinica flower extracts showed a significant(P < 0.05) reduction in fecal egg count up to 84.57%, 77.06% & 63.89% and worm burden of 91.43%, 81.43% & 70.71% at a respective dose levels. In addition, a significant(P < 0.05) reduction in liver granuloma score was observed in all H. abyssinica administered dose groups and E. kebericho at 1 200 mg/kg/day dose group as compared to infected untreated control group. Conclusions: H. abyssinica and E. kebericho crude extracts show a promising antischistosomal activity.展开更多

It may or may not have clinical manifestations. They include low back pain and/or lower limb pain and weakness, and double incontinence. Early diagnosis and treatment provide a good outcome. Aim: To describe the clinical, radiologic, and therapeutic data of 7 patients with Spinal Schistosomiasis. Patients and Methods: In this retrospective clinical case study, the medical records of 7 patients with spinal cord pathologies admitted to Aswan University Hospital from May 2014 to May 2017 were reviewed. All were male aged from 17 to 30 years old (mean ± SD, 20 ± 9.5 yr.;median 21 yr.), with neurological deficit in the form of lower limb weakness and sphincter disturbance. All were treated by decompressive laminectomy and debulking of the intramedullary lesion followed by medical treatment. Results: The outcome of our patients was good as 4/7 patients (57%) presented a full recovery, 3/7 patients (43%) presented a partial recovery without functional limitations and none presented a partial recovery with limitations or no response. Conclusion: High index of suspicion should be raised in the differential diagnosis of patients with clinical or radiological evidence of Spinal Cord Schistosomiasis, as early diagnosis can guarantee a better prognosis and avoid the occurrence of serious sequels. The association of corticosteroids and antischistosomal drugs is related to the best outcome. The role of surgery is decompression, particularly in the granulomatous or pseudotumoral form, and to obtain material for definite histopathological diagnosis in doubtful cases.展开更多
