The posterior interosseous nerves of 58 cadaver forearms of black South Africans were dissected to study their order of branching. In 43 specimens (74%), the most common order of branching was: extensor carpi radialis brevis; supinator; extensor digitorum; extensor carpi ulnaris; extensor digiti minimi; abductor pollicis longus; extensor pollicis brevis; extensor pollicis longus and extensor indicis. In 15 specimens (26%) different variations of the nerve were observed, some of which are reported for the first time.

The objective of the study was to evaluate the chronic cytotoxic effect of very low nontoxic aluminum (Al) in the drinking water of rats. The control group (10 rats) received deionized water, whereas the two experimental groups (10 rats each) received Al in a dose of 5 mg and 20 mg/kg bw/day, respectively. Al was applied in their drinking water during the 6-month duration of the study.

Variations of the arterial and venous pubic anastomoses (APA, VPA) were studied. Forty-four percent of the APA were replaced by an obturator artery arising from the inferior epigastric and 25% by an obturator artery arising from the external iliac. Seven percent of the VPA were replaced by a single obturator vein, 37% by the superior companion of a double obturator vein, and 2% by a double obturator vein.

The sample was obtained from four one-year-old Chacma baboons (Papio ursinus). Blocks of tissue were prepared according to the method of Farnum and Wilsman (1983) and examined by transmission electron microscopy.
