Phosphorylation of D-glucosamine by rat liver glucokinase.
D-Glucosamine was found to be phosphorylated by a rat liver extract in the presence of a high concentration of glucose, which was formerly believed to be a strong competitive inhibitor of this reaction. Results suggested that glucosamine may be phosphorylated by high Km hexokinase, i.e. glucokinase [EC 2.7.1.2]. The enzyme involved was separated from specific N-acetyl-D-glucosamine kinase [EC 2.7.1.59]. The phosphorylation was not inhibited by a physiological level of glucose or glucose 6-phosphate, which strongly inhibited low Km hexokinase. The apparent Km of glucokinase for glucosamine was estimated as 8 mM, which is ten times that of low Km hexokinase.

Desmoplastic fibroma of bone.
We present a rare case of benign intraosseous desmoplastic fibroma, occurring in the tibial bone of a 48-year-old woman. The plain film features consist of a lytic, expansile lesion, in the metaphysis and epiphysis of the bone. We present a case involving the long bone in which the correct diagnosis was suggested by CT and MRI. The appearance of the lesion on CT and MR is described.

[Decision-making style among hemodialysis patients].
UNLABELLED: The purpose of this descriptive study was to identify the decision-making style among the dialysis patients. Subjects were a Convenience sample of hemodialysis patients who agreed to participate this study. The data was collected through semi-structured interviews. The interviews were recorded on the tape and transcribed. Decision-making episodes were picked and interpreted by searchers. Data was analyzed based on the Inductive Theory Approach. RESULT: Subject were 21 patients from 4 hospitals. The mean age was 51.1 and the mean duration after they started the hemodialysis was 9.1 years. The 16 decision-making styles were identified: accept, unvacillate, resignation, compromise, perseverance, challenge, self-activation, groupie, crisis-avoidance, withdrawal, prudent, reserve, escape, refusal, dogmatic, and entrust. These 16 decision-making styles were characterized by the reality oriented perception, the constructive regimes, the higher quality of social support. On the other hand, the passive decision-making styles were characterized by the distorted perception, the passive regimes, and the poor social support. DISCUSSION: The reality orientation, energy, openness, values system were discussed as key factors which determined the decision-making style among hemodialysis patients. The nursing approach supporting the patients to make their decision were discussed.
