with new connective tissue. The basement membranes of the
tubes are thickened, and are accompanied by bands of con-
nective tissue. The intertubular capillaries are partly dilated,
partly small and fatty.
The atrophy consists, therefore, in a suppression of the
function of a number Buy Aerovent of the tubes, with obliteration of some
of the Atrovent Online blood-vessels and increase of the interstitial tissue.
Both processes, that in tlie epithelium and that in the con-
nective tissue, can occur separately, but are usually combined.
4. Amyloid Degeneration. — He describes this form in
much the same way as other authors. He regards the degen
eration of tlie vessels only as a complication Order Atrovent Online of the paren-
chymatous and interstitial change.
5. The Fatty Kidney. — There is an infiltration of the epi-
thelium with fat, or a fatty degeneration. The condition is
described in the same way as the diffuse granular degeneration
ofKlebs.
It will be seen from the preceding abstracts that, while
these authors have apparently observed the same forms of kid-
ney-diseases, their interpretation of them is very different.
1. They all describe a form of disease in which the kidney
is large and the cortex white, with or without hsemorrhagic
spots, and which occurs with scarlet fever, and after exposure
to cold.
Frerichs describes this as tlie Generic Atrovent first and second stage of
Bright's disease. The principal feature of the lesion is the ex-
udation of fibrine into and between the tubes. The degenera-
tion of the epithelium is secondary to this.
Yirchow gives the most prominent share to the changes in
the epithelial cells and their parenchymatous inflammation.
George Johnson considers the lesion to consist in a des-
quamation of the renal epithelium, and does not speak of any
exudation between the tubes
CHEONIC DIFFUSE NEPHRITIS. 249
Grainger Buy Cheap Atrovent Stewart describes the lesion in the same way as
Frericlis, but does not put any exudation between the tubes.
Dickinson describes the lesion under the name of acute
tubal nephritis, in the same way as Johnson does.
Klebs calls Order Atrovent it interstitial nephritis. There is an accumu-
lation of serum in the lymphatics and interstitial tissue, and an
emigration of white blood-oflobules into the interstitial tissue.
The degeneration of the epithelium is secondary to this,
Rindjleiscti admits two forms, one in which the princi-
pal changes are in the epithelium, and one in which Purchase Atrovent Online they are
in the interstitial tissue.
Rosendein^ like Rindfleisch, admits two forms.
2. They describe a chronic form Cheap Atrovent of disease, occurring in
connection with exhausting diseases, and not attended by
acute symptoms. The kidney is of medium size, or large ; the
cortex white and opaque. Buy Atrovent Online
Freriohs does not describe this.
Johnson describes the condition under the names of chronic
non-desquamative disease, granular fat kidney, and mottled fat
kidney. In the granular fat kidney the white cortex is mot-
tled with yellow spots; in the mottled fat kidney the cortex
is mottled red and yellow. The lesion consists in a fatty and
granular degeneration of the tubes.
Stewart calls it simple fatty degeneration.
Dickinson calls it chronic tubal nephritis.
Klebs calls it diffuse granular degeneration, and the pro-
cess a degeneration and not an inflammation.
Rindfleisch includes it under the name of parenchymatous
nephritis.
Rosenstein describes two varieties under the names of
catarrhal nephritis and fatty degeneration.
3. They describe a form of disease characterized by atrophy
of the kidney, with thinning and roughening of the cortex.
Frerichs makes this the third stage of Bright's disease.
Johnson calls it chronic desquamative nephritis.
Stewart describes it under two different heads, as the
third stage of the inflammatory form, Buy Atrovent and as the cirrhotic
or contracting kidney.
DicMnson calls it granular degeneration.
250 CHR0JV7IC DIFFUSE liTEPHRITIS,
Klebs calls it the third stage pf interstitial nephritis.
Ixindjieisch says it may be the result of parenchymatous
or of interstitial nephritis, or of both Purchase Atrovent combined,
