CALCIUM-METABOLISM OF THE RABBIT LENS

EXPERIMENTAL EYE RESEARCH, 36(1), 57–66.

By: M. Mcgahan*, B. Chin* & P. Bentley*

MeSH headings : Animals; Calcium / metabolism; Calcium-Binding Proteins / metabolism; Hydrogen-Ion Concentration; In Vitro Techniques; Lens, Crystalline / drug effects; Lens, Crystalline / metabolism; Male; Osmolar Concentration; Rabbits
TL;DR: Efflux of Ca from the lens was unchanged, under experimental conditions, by metabolic inhibitors, by EGTA, verapamil, TFP and vanadate, and in the presence of metabolic inhibitors (iodoacetate plus cyanide) lenticular Ca rises. (via Semantic Scholar)

SOME OBSERVATIONS ON THE MAGNESIUM-METABOLISM OF THE RABBIT LENS

EXPERIMENTAL EYE RESEARCH, 36(1), 67–73.

By: M. Mcgahan*, B. Chin* & P. Bentley*

MeSH headings : Animals; Calcimycin / pharmacology; In Vitro Techniques; Lens Cortex, Crystalline / drug effects; Lens Nucleus, Crystalline / drug effects; Lens, Crystalline / drug effects; Lens, Crystalline / metabolism; Magnesium / metabolism; Male; Osmolar Concentration; Rabbits
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

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)
