This study showed the blood appearance kinetics of muscle injury markers and some metabolites. It is suggested that the increase in these enzymes came primarily from muscle damage, rather than liver damage, and that white blood cells are selectively mobilised independently of haemoconcentration. The early appearance of muscle injury markers in this kind of exercise was also shown.

(99m)Tc-MDP SPECT provides a quantitative method for assessing mandibular condylar uptake as a reflection of the activity of mandibular growth. The maximum pixel value of a 2-D ROI using external standardization and the right to left ratio of the condylar uptake provide the potential for quantitative evaluation of patients with mandibular asymmetry. These parameters will be further evaluated in an upcoming clinical investigation.

Tissue cholestasis is a histologic feature in some patients with alcoholic liver disease, but its significance is unknown. We studied prospectively the clinical, laboratory, and histologic findings of 306 chronic male alcoholics in whom liver tissue was available. Tissue cholestasis permitted identification of two groups: group I, absent or mild cholestasis (239 patients), and group II, moderate to severe cholestasis (67 patients). Statistical evaluation was performed by Student's t test and regression analyses. In patients with tissue cholestasis, 97% had elevated serum cholylglycine levels, while only 61% had significant jaundice (serum bilirubin greater than 5 mg/dl). In patients without tissue cholestasis, 66% had elevated serum cholylglycine and 13.5% jaundice. Highly significant statistical correlations (P less than 0.0001) were found between cholestasis and malnutrition, prothrombin time, AST, alkaline phosphatase, bilirubin, Maddrey's discriminant function, serum cholylglycine level, albumin, and histologic severity score. In group I, 54% survived 60 months versus 22% in group II (P less than 0.0001). Highly significant statistical correlations (P less than 0.0001) were noted between serum cholylglycine levels and the parameters enumerated earlier, but not with survival. We conclude that tissue cholestasis is a highly significant prognostic indicator of outcome in alcoholic hepatitis and is more consistently associated with bile salt retention than jaundice.
