By A. Jefferis Turner, m.d. (Intercolonial Medical Journal of Australasia.)?After describing the spread of anchylostomiasis in Australia, Dr. Turner gives his experience of treatment. He had disappointing results with calomel, santonin, male fern, naphthalin, naphthol, thymol, and other drugs. Ordinary doses of thymol, such as five grains thrice daily, he had found utterly useless; but on readi...

Most of the methods described for the determination of acetoin and biacetyl are based on the original Lemoigne-van Niel procedure (1, 2), which depends upon the formation of insoluble nickel dimethylglyoxime when biacetyl is treated with hydroxylamine in the presence of a nickel salt; acetoin is similarly determined after oxidation to biacetyl by heating with ferric chloride. In a recent modifi...

A procedureis presentedfor the automated determination of acid phosphatase activity in biological materials from either plant or animal origin. The Technicon N-i flow diagram has been simplified, and the reagents for the measurement of enzymatically produced phenolic substanceshave been modified without lossof range or sensitivity. Both phenyiphosphateand a-naphthylphosphate, introduced by Babs...

The far-infrared THz spectra of naphthalene, a-naphthol, b-naphthol, biphenyl and anthracene have been measured using THz time-domain spectroscopy. The low-energy vibrational modes of measured molecules are discussed based on their characteristic and common features. The complex dielectric functions are obtained. Meanwhile, it is shown that the experimental results can be well fitted by a stand...

Sterile batch experiments were conducted to investigate the effects of pH, dissolved O2 concentration, and reaction time on interaction of 0.1 mM 14C-1-hydroxynaphthalene [1-naphthol] with poorly crystalline Al(OH)3(s). Negligible (<4%) sorption of 1-naphthol to Al(OH)3(s) was observed after 20 h reaction time (conditions dark, w/ O2). However, a significant increase in sorption of 14C labeled ...

The inflammatory destruction of cartilage in rat adjuvant arthritis has been studied by histochemistry and autoradiography. Naphthol-AS-D-chloroacetate esterase has been used as a marker for polymorphs. The evidence presented here shows that polymorphs accumulate at the cartilage-pannus border and in areas of cartilage loss. These cells appear therefore to be of decisive importance for the dest...
