Degeneration Accompanying Inbreeding

Inbreeding Degeneration in Tetrahymena.

NBREEDING degeneration has been observed in many higher plants and animals I and its physical basis and its bearing on the genetic economy of these organisms have been widely discussed (GOWEN 1952; LERNER 1954). While some genetic problems such as gene action, mutagenesis and genetic recombination have been actively and profitably pursued with microorganisms, relatively little work on inbreedin...

Progression of spondylolysis to isthmic spondylolisthesis in an adult without accompanying disc degeneration: a case report.

Progression of spondylolysis to spondylolisthesis in adults is very rare. It is always accompanied by disc degeneration at the slip level, or at a lower level. The intervertebral disc is indeed the main structure that opposes the anteriorly directed shear forces. Of course, the disc degeneration might also be a consequence, rather than a cause of the slip. The authors describe an unusual case o...

Amino-aciduria accompanying untreated pernicious anaemia and subacute combined degeneration of the spinal cord.

Weaver and Neill (1954) reported abnormal excretions of taurine, sometimes accompanied by over-excretion of lysine, cystine, and leucine, in the urine of five patients suffering from pernicious anaemia. In one patient with subacute combined degeneration of the spinal cord in whom the blood picture was normal, they found that taurine alone was excreted in abnormal quantities. After treatment wit...
