Distribution of the motor nerve supply of the thenar and hypothenar muscles of the hand

The distribution of the muscular branch of the median nerve to the thenar muscles and the deep branch of the ulnar nerve to the hypothenar muscles was studied in 30 palmar regions from adult cadavers of both sexes ranging from 40 to 70 years. The patterns of the distribution of the motor branch of the median nerve were classified into three groups according to the site, direction and number of individual branches. In ten of the 30 hands, a correlation was found between the ulnar and median nerves. The deep branch of the ulnar nerve gave three motor branches to the hypothenar muscles and its end usually supplied the deep head of the flexor pollicis brevis

Study of circulating progenitor cells and granulocyte macrophage colony stimulating factor in preeclamptic pregnancies

To study the circulating progenitor cells in preeclampsia, 20 patients with preeclampsia, 24 healthy pregnant females in the 3rd trimester and ten nonpregnant healthy age matched females were included in this work. For all subjects, number of circulating progenitor cells, serum level of granulocyte macrophage colony stimulating factor [GM-CSF] and total and absolute leukocytic count were investigated. It was concluded that the number of circulating progenitors decreased in preeclamptic patients due to a decreased production of colony stimulating activity by the diseased placenta. The negative correlation between neutrophil count and number of GM-CFCs showed that other factor[s] could participate in the production of neutrophils in this multi- factorial disease
