Arylsulphatase A and acid phosphatase activities in plasma and leucocytes during LPS fever in the ox (Bos taurus).
Intravenous injection of E. coli LPS (0.5 micrograms/kg) produced the biphasic elevation of rectal temperature (TR) in conscious oxen. The fever was accompanied by a significant increase of the arylsulphatase A (AsA) activities in plasma and in mononuclear leucocytes. In polymorphonuclear cells a substantial decrease of the AsA activity after 1 hr fever was observed. After 3.5 hr of fever the polymorphonuclear activity of AsA restored to normal found before LPS administration. In contrast with AsA, the pyrogenic dose of LPS caused negligible changes of the acid phosphatase (AcP) activities in the sampled materials. Daily-repeated injections of pyrogen into the same oxen attenuated magnitudes of fever as well as AsA responses in plasma and granulocytes. Heat-induced hyperthermia provoked only minute changes of the AsA and AcP.
