Stored product mites (Acari: Astigmata) infesting food in various types of packaging.

From 2008 to 2014, stored product mites have been reported from prepackaged dried food on the market in the Czech Republic. The infestation was by Carpoglyphus lactis (L.) in dried fruits and Tyrophagus putrescentiae (Schrank) in dog feed.

Isoenzymes of aspartate aminotransferase in chronic liver diseases.

The total activity and activity of the cytoplasmic and mitochondrial isoenzyme of aspartate aminotransferase was examined in blood plasma of 56 patients with chronic liver diseases (chronic hepatitis in 27, liver cirrhosis in 23, secondary neoplastic effection of the liver in 6). All the patients with biochemically active forms of liver disease manifested increased the total as well as cytoplasmic enzyme activity, as compared with control group, 57% of the patients manifested simultaneously also increased activity of the mitochondrial isoenzyme. In 13% of the patients with stabilised forms of liver diseases manifested isolated increase of the mitochondrial isoenzyme activity.

The source and clinical significance of alkaline phosphatases in liver diseases.

The authors studied total serum alkaline phosphatase (E.C. 3.

Relationship of multiple forms of lactate dehydrogenase to cholestasis.

The source and clinical significance of serum alkaline phosphatases in neoplastic blood diseases.

Total serum alkaline phosphatase activity and its isoenzymes were studied in 126 patients sent to hospital with a neoplastic blood disease. They comprised 63 patients with a lymphoreticular neoplastic disease, 17 with immature stem-cell leukaemia, 11 with a plasmocytoma, 16 with lymphocytic leukaemia, 4 with polycythaemia and 9 with the myelofibrosis syndrome. Evaluation of the serum alkaline phosphatase isoenzymes significantly enhances the efficiency of the diagnosis and the organ specificity of the enzymes in these conditions.
