| [relationship between the endocochlear potential and metabolism in the vascular stria of the inner ear]. | effects of dihydrostreptomycin, etacrine acid and atph on the endocochlear potential in guinea-pigs depended on the dosage and means of administration. dihydrostreptomycin suppressed the potential only when perfusing the perilymphatic space or being microinjected into the endolymphatic duct. i. v. administration of etacrine acid suppressed the potential with its following partial restoration. i.v. administration of atph in large doses suppressed the potential for a short period but did not preve ... | 1977 | 69557 |

| silver staining the caveolae intracellularis of smooth muscle. | bodian silver staining of guinea-pig taenia coli produces a regular distribution of silver at the periphery of the smooth muscle cells. electron microscopic analysis of this precipitate revealed that the membrane of the caveolae intracellularis was the only structure at the periphery of the cells that consistently exhibited a high affinity for silver. thus, this staining method demonstrates that caveolae are distributed over most of the cell surface in an orderly pattern. | 1977 | 69622 |

| autoantibodies to zona pellucida: a possible cause for infertility in women. | human and pig ovaries were tested by agar gel diffusion and found to contain several cross-reacting (common) antigens. at least one common antigen was located in the zona pellucida as determined by indirect immunofluorescence. serum samples from 22 infertile women were tested on pig eggs by immunofluorescence, and six of these samples produced strong and nine produced moderate reactions with the zona pellucida. the autoantibodies may be responsible for infertility in these women. | 1977 | 70076 |
