A procedure has been developed for the determination of ferbam (ferric dimethyldithiocarbamate) by converting it into ferbam-phenanthroline complex, which is dissolved in acetone + water (1 + 1 by volume), and the absorbance measured at 490 nm against a reagent blank. Beer's law is obeyed over the concentration range 0–8–20-0 mg litre?1 in the final solution. The method is sensitive, selective and can be used for the direct determination of ferbam in commercial samples, in mixtures with various other dithiocarbamates (ziram, zineb, maneb, etc.) and from grains (rice and wheat) and apples. The limit of determination from foodstuffs is 0–4 mg kg?1. 相似文献
A number of quinazolin-4(3H)-one carbothioamides, pyrazoles, pyrazolones and tetrazole derivatives have been synthesised by the reaction of 2-hydrazino-3-(4-substituted phenyl)-quinazolin-4(3H)-ones with the appropriate aryl isothiocyanate, acetyl acetone, ethylacetoacetate and nitrous acid. All the compounds were tested in vitro for antibacterial, insecticidal and antifungal activity and found to have some activity. 相似文献
Background: An oviduct-specific glycoprotein, OVGP1, is synthesized and secreted by non-ciliated epithelial cells of the mammalian oviduct which provides an essential milieu for reproductive functions. The present study reports the effects of recombinant buffalo OVGP1 that lacks post-translational modifications, and native Buffalo OVGP1 isolated from oviductal tissue, on frozen-thawed sperm functions and in vitro embryo development.Results: The proportion of viable sperms was greater(P 0.05) in the recombinant OVGP1-treated group compared to the native OVGP1-treated group at 2 h, 3 h, and 4 h of incubation. The proportion of motile sperms at3 h and 4 h of incubation; and membrane-intact sperms at 4 h was greater(P 0.05) in the native OVGP1-treated group compared to the control and recombinant OVGP1-treated groups. The proportion of capacitated and acrosome-reacted sperms was greater(P 0.05) in the native OVGP1-treated group compared to the recombinant OVGP1 group at 4 h. The rates of cleavage of embryos and their development to the blastocyst stage were greater(P 0.05) in the presence of either native or recombinant OVGP1 in comparison to control at 10 μg/mL concentration as compared to 5 or 20 μg/mL.Conclusions: The study suggests that both native and recombinant OVGP1 impart a positive effect on various sperm features and in vitro embryo development. However, native OVGP1 was found to have a more pronounced effect in comparison to recombinant non-glycosylated OVGP1 on various sperm functions except viability. Hence,our current findings infer that glycosylation of OVGP1 might be essential in sustaining the sperm functions but not the in vitro embryo development. 相似文献
