TL;DR: Phacoemulsification with and without anterior and equatorial capsular vacuuming led to less initial LEC density in the capsular bag than ECCE, however, because cell proliferation rates among the 3 groups were only marginally affected, near 100% removal of LEC at the time of cataract extraction may be necessary to prevent PCO.

TL;DR: The redistribution of Fe within the cell after 20 h of Tempol treatment appears to render the cells more vulnerable to oxidative stress, likely due to its effects on Fe metabolism, perhaps by reducing the availability of Fe for incorporation into ferritin and Fe-dependent enzymes as well as enlarging a low molecular weight pool of Fe which may be capable of catalyzing damaging free radical reactions.

TL;DR: Incubation of lenses in solutions containing EDTA or following freezing and thawing suggested that much of the Mg is present in a bound form, and adjustment of the external Mg level in the presence of A-23187 indicated that the internal 'free' Mg concentration was about 3 mM, suggesting that about 35% of the lenticular magnesium is bound.

A PHARMACOLOGICAL ANALYSIS OF CHLORIDE TRANSPORT ACROSS THE AMPHIBIAN CORNEA

JOURNAL OF PHYSIOLOGY-LONDON, 325(APR), 481–492.

By: P. Bentley* & M. Mcgahan

MeSH headings : 4,4'-Diisothiocyanostilbene-2,2'-Disulfonic Acid; 4-Acetamido-4'-isothiocyanatostilbene-2,2'-disulfonic Acid / analogs & derivatives; 4-Acetamido-4'-isothiocyanatostilbene-2,2'-disulfonic Acid / pharmacology; Animals; Biological Transport, Active / drug effects; Bucladesine / pharmacology; Bufo marinus; Bumetanide / pharmacology; Calcimycin / pharmacology; Chlorides / metabolism; Cornea / metabolism; Dinoprostone; Epinephrine / pharmacology; In Vitro Techniques; Meclofenamic Acid / pharmacology; Models, Biological; Prostaglandins E / pharmacology; Quinacrine / pharmacology; Trifluoperazine / pharmacology
TL;DR: Active Cl, but not Na, transport across the toad cornea was inhibited by mepacrine, which is a phospholipase A2 inhibitor; trifluoperazine, which blocks the action of calmodulin; and meclofenamic acid, which inhibits synthesis of prostaglandins. (via Semantic Scholar)

STIMULATION OF TRANS-EPITHELIAL SODIUM AND CHLORIDE TRANSPORT BY ASCORBIC-ACID - INDUCTION OF NA+ CHANNELS IS INHIBITED BY AMILORIDE

BIOCHIMICA ET BIOPHYSICA ACTA, 689(2), 385–392.

By: M. Mcgahan* & P. Bentley*

MeSH headings : Amiloride / pharmacology; Animals; Ascorbic Acid / pharmacology; Biological Transport, Active / drug effects; Bufo marinus; Chlorides / metabolism; Cornea / metabolism; Epithelium / drug effects; Epithelium / metabolism; Ion Channels / drug effects; Ion Channels / metabolism; Kinetics; Pyrazines / pharmacology; Sodium / metabolism
TL;DR: The effect of ascorbic acid on Isc when it was on the aqueous humor side of the cornea could be blocked by bumetanide but that due to the vitamin's presence on the tear side was unchanged, and these effects were additive. (via Semantic Scholar)

ALPHA-AMINOISOBUTYRIC-ACID EFFLUX FROM THE CORNEA OF THE TOAD, BUFO-MARINUS

JOURNAL OF PHYSIOLOGY-LONDON, 315(JUN), 253–266.

By: M. Mcgahan

MeSH headings : Aminoisobutyric Acids / metabolism; Animals; Biological Transport / drug effects; Bufo marinus; Cornea / metabolism; Endothelium / metabolism; Epithelium / metabolism; Hydrogen-Ion Concentration; In Vitro Techniques; Sodium / pharmacology
TL;DR: Although the largest amount of AIB accumulated by the cornea was present in the epithelium, evidence is presented that the endothelium and stromal keratocytes may also concentrate and retain amino acids. (via Semantic Scholar)

INHIBITORY-ACTION OF DIDS ON CHLORIDE TRANSPORT ACROSS THE AMPHIBIAN CORNEA

JOURNAL OF PHYSIOLOGY-LONDON, 304(JUL), 519–527.

By: P. Bentley* & M. Mcgahan
