The determination of serum and urinary enzymes levels is widely used to assess both liver and kidney damage. However, during obstructive liver disease there is a concurrent elevation in the concentrations of serum and urinary hydrophobic bile salts, which have been reported to alter the activity of a number of enzymes making the accurate assessment of enzymic activity difficult [l]. Bile salts ...

I t has been previously reported (1) that brains of mice infected with the Theiler FA strain of mouse encephalomyelitis virus show marked inhibition in the rate of glucose phosphorylation. Since such impairment in the utilization of the most essential substrate of brain metabolism may be related to the neuron destruction in the course of the virus infection, its mechanism was investigated furth...

Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...
