Quality of life of patients operated for lumbar stenosis at the Yaoundé Central Hospital.

Several studies have been conducted in many African countries on lumbar stenosis but none on the quality of life of patients after surgery. We conducted this study to evaluate the quality of life of patients following surgery indicated for lumbar stenosis. A cross-sectional study from January 2010 to December 2015 in the neurosurgery department of the Yaoundé Central Hospital.

Aryl benzofuran derivatives from the stem bark of Calpocalyx dinklagei attenuate inflammation.

Calpocalyx dinklagei Harms (Fabaceae) is a tropical medicinal tree, which is indigenous to Western Africa. A phytochemical study of this local plant species from its stem bark has led to the isolation of two previously undescribed aryl benzofuran derivatives, named dinklagein A and B, together with eight known compounds. Their chemical structures were elucidated by use of extensive spectroscopic methods (IR, HREI-MS and 1D and 2D NMR).
