Ocular Hypotensive Effect of the α2-Adrenergic Agonist, Lofexidine

Description: A selective a2-adrenergic agonist, lofexidine, significantly reduced intraocular pressure (lOP) in intact ocular normotensive NZW rabbits, producing a differential dose-dependent decrease in IOP in'the ipsilateral and contralateral eye. Contralateral IOP reduction was most observable at low doses. Unilateral superior cervical ganglionectomy and extraocular muscle excision studies were undertaken to elucidate the factors influencing differential IOP reduction by lofexidine. Similar significant c… more

Degradation of Phenolic Acids by Azotobacter Species Isolated from Sorghum Fields

Description: Sorghum plants excrete phenolic acids which reduce subsequent crop yields. These acids accumulate in field soil by combining with soil and clay particles to form stable complexes which remain until degraded by bacterial metabolism. The amount of phenolic acids in soil samples were obtained by gas chromatography measurements, while Azotobacter populations were obtained by plate counts in 40 sorghum field samples from Denton County, Texas. One can conclude that increasing the Azotobacter populati… more

The Reproductive Consequences of Carriers of Methylenebisacrylamide-Induced Balanced Reciprocal Translocations in Mus Musculus

Description: N,N'-methylenebisacrylamide (MBA) was studied because of its effectiveness in inducing heritable translocations in germ cells of male mice. The health impact of translocations was studied through anatomical analysis of the progeny of semisterile translocation carriers. As expected, the semisterility of translocation carriers resulted primarily from embryonic death during periimplantation stages due to unbalanced chromosome sperm segregants. Among conceptuses that survived to mid- and late-gesta… more
