After World War II, Harvard researcher Edwin Joseph Cohn (1892-1953) devised a small centrifuge in which a donor's blood could be quickly separated into its components and stored more efficiently. The centrifugal force employed divides the heavier red blood cells from the lighter plasma.

Beginning in October 1948, weekly meetings of the Formed Elements Group of Cohn's laboratory staff and associates were held to discuss research and developments in plasma fractionation and blood preservation and storage. These meetings resulted in the establishment of the Blood Characterization and Preservation Laboratory in January, 1951.

While the first bowls for the Cohn centrifuge were made of glass, the examples here show later refinements, the one made of stainless steel, the other a single use, disposable bowl, developed by Allen D. Latham, Jr.

Latham Bowl, Plastic, Single-Use, 1972-2007. Two clear and white plastic components. The largest is a bulbous plastic bell-shaped body. The body appears to have two main pieces: an exterior clear plastic shell and a white plastic interior bulb. The second piece of the unit is a clear plastic drum with a long metal cylinder threaded through its center.

Cohn Centrifuge, stainless steel, 1952-1972. Two metal components. The majority of the piece is composed of a bulbous metal body that tampers to a circular flat end. The widest point of the body has a thick metal band around its diameter. The body's hallow interior has several distinct chambers. The second piece of the cell separator inserts into the larger body. It is composed of a circular metal drum from which extends a thin cylinder with a plastic tip. When inserted into the body only the base of the drum is visible.

This collar was worn by a Boston streetcar motorman who was subject to attacks of dizziness and loss of consciousness on the job. Upon examination at Massachusetts General Hospital, it was determined that when the motorman turned his head, his stiff shirt collar pressed against the right carotid sinus, triggering a fainting attack. "Pulse and blood pressure measurements were made with the patient turning his head from side to side while wearing one of his celluloid collars. These movements caused pressure on the carotid sinuses, and resulted in slight slowing of the heart rate, fall in blood pressure as much as 40mm. Hg systolic, sometimes dizziness, but not fainting. The patient was advised to wear a soft collar, which he has done for the past month. In that time has had no more attacks of dizziness or fainting."

Dr. Soma Weiss (1899-1942) described this case in his article, "Carotid sinus reflex in health and disease," published in Medicine, v. 12 (1933).

The specimen is of dissected superior and inferior maxillary nones showing arrested development of permanent tooth germs, natural absorption of roots of temporary centrals. Also a few examples of extracted permanent teeth with arrested development-(showing 6 teeth). These specimens are mounted in glass globe.

]]> ]]> ]]> Border lines of knowledge, in some provinces of medical science is a published and somewhat expanded version of Holmes’ introductory lecture to the students at Harvard Medical School at the opening of term on November 6, 1861. Although he refers to human anatomy as “an almost exhausted science,” Holmes goes on to list some of his own anatomical observations:

“The nucleated cells found connected with the cancellated structure of the bones, which I first pointed out and had figured in 1847, and have shown yearly from that time to the present, and fossa masseterica, a shallow concavity on the ramus muscle, which acquires significance when examined by the side of the deep cavity on the corresponding part in some carnivore to which it answers, may perhaps be claimed as deserving attention."

Holmes continues, commenting on the discovery of this artifact, as he notes how:

"I have also pleased myself by making a special group of the six radiating muscles which diverge from the spine of the axis, or second cervical vertebra, and by giving to it the name stella musculosa nuchæ. But this scanty catalogue is only an evidence that one may teach long and see little that has not been noted by those who have gone before him.”

The soldier entered Massachusetts General Hospital on November 3, 1865. At that time the arm swung freely without pain. Surgeon Henry Jacob Bigelow removed three more pieces of bone with a trephine, scraped the interiors with a gouge, wired the two sections together, and splinted the arm exterior. No union occurred.
On March 1, 1866 Bigelow performed a second operation with further bone removal and wiring resulting in a stiffening of arm, but patient fell on June 10, 1866 and re-broke the humerus. On January 12, 1867 a third operation was performed with further wiring resulting in paralysis of the upper arm, although no nerve was known to be severed. This operation resulted in union of the fracture but the paralysis continued. The post-operative arm was seven inches shorter than the patient's healthy arm.

Folch-Pi and Lees describe the cumbersome process in a 1951 article in the Journal of biological chemistry, “To a filtrate from proteolipide A was added an equal volume of acetone, and, after mixing, the solution was allowed to stand at 4° overnight. A precipitate that had formed was collected by centrifugation and dried in a vacuum desiccator at room temperature to constant weight. 0.6 gm. of a white powder was obtained (proteolipide B).”
