Flashcards in GPHT LAB - Adv and Disadv Part 2 Deck (35):
1

adv
prevents formation of troublesome post mortem precipitated acid formalin pigment

10% buffered formalin

2

disadv
preserves poorly the RBC

Heidenhain's Susa solution

3

disadv
prolonged fixation of large specimens

Heidenhain's Susa solution

4

adv
excellent as routine fixative

formol sublimate
formol saline sublimate

5

adv
produces little or no shrinkage of tissues

formol sublimate
formol saline sublimate

6

disadv
does not preserve the thick slices of tissues thus not to be used for more than 1 cm thick specimen sections

formol sublimate
formol saline sublimate

7

adv and disadvantages are similar to formol sublimate

formol saline sublimate

8

adv
permits excellent staining of nuclei

zenker's solution

9

adv
recommended for tissues to be stained by one of the trichrome technique

zenker's solution

10

disadv
not stable after the addition of acetic acid

zenker's solution

11

adv
gives excellent nuclear fixation

zenker's formol

12

adv
preserves cytoplasmic granules well

zenker's formol

13

adv
excellent fixative for pituitary and BM tissue

zenker's formol

14

disadv
prolonged fixation of tissue produces brown scum

zenker's formol

15

adv
yellow stain is useful when handling fragments of tissues

bouin's solution

16

disadv
should never be used for preserving kidneys because of extreme distortion

bouin's solution
bouin's fluid

17

adv
excellent for nuclear elements (chromosomes)

flemming's fluid

18

adv
permanently preserves fats

flemming's fluid

19

disadv
deteriorates rapidly thereby it must be prepared immediately before its use

flemming's fluid

20

adv
fixes and dehydrates simultaneously

carnoy's

21

adv
most rapid of all fixatives

carnoy's

22

disadv
causes excessive shrinkage and hemolysis of RBC

carnoy's

23

disadv
only small pieces of tissues may be used

carnoy's
newcomer's

24

adv
gives better nuclear fixation than flemming's fluid

bouin's fluid

25

adv
useful for minute fragments as the yellow color given to tissue makes it easier to locate the specimen

bouin's fluid

26

disadv
cytoplasmic structres such as mitochondria are distorted or dissolved

bouin's fluid

27

adv
tissue require only one change of absolute alcohol before clearing

newcomer's fluid

28

adv
only small amount of fixative is required
5-10x the bulk of the tissue

champy's fluid

29

disadv similar to flemming's fuid

champy's fluid

30

adv
more penetrating than chromium fixatives

regaud's fluid (moller)

31

disadv
preserves fats

regaud's fluid (moller)

32

disadv
needs post-chroming

regaud's fluid (moller)

33

adv
demonstrates Rickettsia and other bacteria

orth's fluid

34

adv
preserves myelin better than buffered formalin

orth's fluid

35

disadv similar to regaud's fluid

orth's fluid
