1898Boston Med. & Surg. Jrnl. 25 Aug. 194/2 In the few cases of purulent ophthalmia that have been treated with protargol the length of the course of the disease has apparently only been slightly shortened, but the severity of the attack has been decidedly lessened. 1907J. H. Parsons Dis. Eye xxix. 580 In more severe cases..protargol, 15 to 20 per cent., should be rubbed into the margins of the lids with a stumpy camel's hair brush. 1938Stain Technol. XIII. 154 Protargol exhibits an isoelectric point roughly about pH 4, at which acidity it is precipitated, hence it might be expected to behave somewhat like a dye by having its selectivity altered by variation of pH of the staining mixture. 1976Acta Zool. LVII. 117 The figures demonstrate the close connection between the surface cilia as shown by SEM [sc. scanning electron microscopy] and the subsurface kinetosomes revealed by the protargol impregnations. |
