Compensatory Hypertrophy of the Spleen
Following the removal of half of the spleen in young adult rats there is a compensatory enlargement of the remaining portion of about 50 per cent while in mature rabbits no such compensatory hypertrophy follows a similar procedure. It is uncertain whether this difference is due to a difference in the function of the spleen in the two species or to the fact that the rats were infected with Barto...
متن کاملCompensatory Hypertrophy of Thymus Gland
We recently have reported several studies concerning the marked stimulation of growth and regeneration that occurs in the thymus gland of rats, of any age, following double suprarenalectomy (1-3). We showed that, as the result of such a procedure, marked hyperplasia of the involuting thymus, with enlargement of the same, occurs with great constancy. In line with these studies, we undertook a se...
متن کاملChemical aspects of compensatory renal hypertrophy.
has been known for over a century that when 1 of the kidneys of a laboratory animal has been surgically removed or is not functioning properly, its partner undergoes a compensatory hypertrophy in which both cell size and cell number increase (20, 21, 33). The mechanism of this compensatory growth is unknown. An obvious possi bility is that it is due to a single kidney having to carry out the wo...
متن کاملFunctional correlates of compensatory renal hypertrophy.
The functional correlates of compensatory renal hypertrophy were studied by micropuncture techniques in rats after the removal of one kidney. The glomerular filtration rate increased to roughly the same extent in the whole kidney and in individual surface nephrons, resulting in a greater amount of sodium delivered to the tubules for reabsorption. The fraction of the glomerular filtrate absorbed...
متن کاملCompensatory Hypertrophy of the Adrenal Cortex
1. Removal of one adrenal in the albino rat is followed by hypertrophy of the remaining gland. In the case of female rats 90 days of age this compensatory hypertrophy amounted to 61 per cent. 2. The increase in size of the whole gland is due entirely to hypertrophy of the cortex. This increase in cortical tissue amounted to approximately 91 per cent and was due in large part if not entirely to ...
