This Month in History: Pay No Attention to the Doctor Behind the Iron Curtain

A young, bespectacled version of the Wizard of Oz, Dr. Frank N. Low, lived up to the great and powerful legacy as a member of LSUMC’s anatomy faculty, venturing behind the Iron Curtain in 1958. His travels came at a time of international tension, but in the name of science, Dr. Low’s survey of electron microscope usage in laboratories across Europe proved invaluable in transcending the iron divide and promoting cross-cultural cooperation.

Remarking on the “exotic” subway of Moscow, the “finely developed” Russian sense of humor, and the popularity of the play, “Klop” the Bedbug, in his interview with the Times-Picayune, Dr. Low appears to have enjoyed his surroundings overseas. He even brought home an object known as the “Tartar Menace” that would turn out not only to be lucky for Low, but also for his research assistant, a previous “Glimpse of the Past” honoree, Dr. Marilyn Zimny, who upon receipt of the figurine received news that she had been awarded a research grant for $28,000. The “Tartar Menace” appears to refer either to a group of indigenous Mongol peoples called the Tatars or Tartars, or the Greek myth of Tartarus, a section of the underworld. Despite its violent etymology, the figurine kept Dr. Low safe from even a stubbed toe on his journey.

And lucky we are that it did, for Dr. Frank N. Low’s contributions to the scientific world were momentous. As of a 1953 article, “Dr. Low’s study provide[d] proof of the existence of a complete covering of the tiny blood vessels in the lung. The presence of this covering, medically known as a pulmonary epithelium has long been in doubt. The significance of [his] discovery is that it is an explanation of how air is excluded from the lung tissue, a destructive process. This is why lung surgery is so cautiously practiced.”

His triumphs also include authoring a renowned text, Electron Microscope: Atlas of Normal and Leukemic Human Blood, acquiring an electron microscope for LSUMC, and pioneering scanning electron microscopy (SEM) and freeze-etch/freeze-fracture technology. His impressive career culminated in his later life with the establishment of the Annual Dr. Frank N. Low Research Day at the University of North Dakota. He returned to LSU at the end of his career to work under Dr. Zimny in the anatomy department until his death in 1998. This memorial article shows how truly respected and loved he was. Now, if only we could find his “Tartar Menace!”

This Month in History: Dr. Marilyn Zimny and the Great Squirrel-Stronaut

This month in 1960, the Times-Picayune ran an article entitled, “Ground Squirrel Called Ideal Space Traveler.” In the article, Dr. Marilyn Zimny, scientist at the LSU Medical School and avid squirrel-enthusiast, tells of the amazing potential for ground squirrels to travel in outer space and to serve as instruments of research on forced-hibernation scenarios and metabolism studies.

Being so adaptable to extreme conditions, the squirrels appear to be ideal candidates for researching regulated slowing of metabolism as they are able to hibernate for long periods of time without damaging their vital organs: heart, brain, and kidneys remain intact. Advancement in this area of reduced energy consummation would possibly provide some insight into the development of a drug that could force a lower metabolism and thus a decreased need for food, water, and oxygen, a state perhaps preferable for astronauts during prolonged space travel and servicemen in cold climates.  This drug could also reduce blood flow during recovery periods after a heart attack or stroke.

Although I can find no evidence that ground squirrels have indeed been launched into space, a slew of animals pre-dated human travel. The list of adventuring animals includes rhesus and squirrel-monkeys as well as mice, rats, rabbits, fruit flies, a guinea pig, a cat, chimpanzees, dogs, etc. These brave animals helped determine the conditions necessary for humans to survive spaceflight.

Dr. Zimny’s fascination with squirrels penetrated her personal life as well as her professional development—professing to own over 160 at the time of this article and in search of more (an abundance can apparently be found in some Chicago golf courses). She authored “Metabolism of some carbohydrate and phosphate compounds during hibernation in the ground squirrel,” published in the Journal of Cellular and Comparative Physiology, “Carbohydrate metabolism in ground squirrels during the summer season,” published in Comparative Biochemistry and Physiology, among many others. Zimny continued her study of the rodents in order to develop a field of research that would include them as test subjects.

Her career at LSU began in 1954, leading her to a full professorship approximately ten years later. According to one Faculty Vignette, her students “were affectionately known as her ‘ground squirrels.’” She went on to become the first female department head at the LSU School of Medicine in 1975, and although she passed away in January 2006, her legacy lives on in her renown. A recent article on POPSCI tells about the successful induction of hibernation in arctic ground squirrels. Dr. Zimny’s warm regard for the critters appears well-places as they continues to be relevant to the study of metabolism regulation.
