Cardio-pulmonary responses to a given step-up exercise test were studied in 43 patients who previously received various thoracic operations such as pleural decortication, one or two segmental resections, right or left upper lobectomy, plombage or pneumonectomy. Fourteen control subjects were also studied for comparison. Following a 30 minute rest, the step-up exercise was performed to heights of 20, 30 and 40cm, in that order, for 8 to 10 min. at each height. During the rest and the steady-state exercise period, the expired gas was collected for a period of 5 minutes for the determinations of the minute volume, the O2 consumption and the CO2 Output. Alveolar gas samples were a1so taken following the expired gas collection. The heart rate and blood pressure were also checked during the rest and immediately after each exercise. Various cardio-pulmonary functions of the patient at rest were little different from those of the control, except the heart rate which tended to be higher in the patient than in the control. Although the work capacity of the patient was lower than in the control, most patients were able to complete the required exercise test. However, in carrying out a given exercise load, the patient groups had a greater minute volume, the respiratory rate, the O2 consumption and the CO2 output as compared to the control, indicating that the mechanical efficiency is considerably lowered in the patient. Of various patient groups, the work performance was most limited in the pneumonectomy group while the group with one or two segmental resections was little affected. It is suggested that the patient with one or two segmental resections may be allowed to engage in physical activity up to 700 kg-m/min or more while those with pneumonectomy should not exert themselves above 500 k-gm/min.

The aim of present study was to elucidate whether the expression of nm23 protein might be of clinical value as prognostic factor in gastric cancer. The expression of nm23 protein was analyzed using immunohistochemical method in formalin-fixed and paraffin-embedded tissue samples of 76 gastric carcinoma patients. The cytoplasmic immunoreactivity of nm23 protein were detected in 53.9%(41/76). When the immunoreactivity of nm23 protein with TNM status and other histopathologic findings were compared by using Chi-Square test, nm23 was found to have correlations with the lymph node metastasis(p=0.04), the number of metastatic lymph node, and the invasion of lymphatic vessels(p=0.007). But, it has no correlation with TNM status. The conventional prognostic factors such as the depth of invasion, lymph node metastasis, distant metastasis, Borrmann type, size of tumor, and the curability of operation was found to have strong correlation with the survival time(p<0.003). But, the expression of nm23 protein was not significantly correlated with that in survival analysis. These results showed that the expression of nm23 protein is not a useful prognostic indicator in gastric cancer.

BACKGROUND: Microalbuminuria predicts cardiovascular events in diabetic and non-diabetic patients. But, few studies have addressed the relationship between microalbuminuria and cerebral infarction. We determined the incidence of microalbuminuria in non-diabetic subjects with cerebral infarction and investigated the relationship between urinary albumin excretion and risk factors of the stroke. METHODS: Urinary albumin excretion rate, 24 hours blood pressure monitoring, fasting serum lipid profiles, fibrinogen, fasting glucose, insulin and c-peptide were evaluated in 50 non-diabetic patients with acute cerebral infarction and matched 48 controls. RESULTS: Microalbuminuria was detected in 23 of 50(46%) patients with acute cerebral infarction and 4 of 48(8%) control subjects. Hypertension was present in 13 of 23(57%) microalbuminuric patients and 9 of 27(33%) non-microalbuminuric patients. In the microalbuminuric patients with cerebral infarction, diastolic blood pressure and fasting glucose were significantly greater than the control group. But, no difference in systolic blood pressure, lipid level, fibrinogen, fasting insulin and c-peptide level. CONCLUSIONS: The prevalence of microalbuminuria in patients with cerebral infarction was higher than controls and it was associated with increased diastolic blood pressure(DBP) and fasting blood glucose(FBS). Therefore, microalbuminuria is associated with thrombogenic cerebral infarction and it was partly mediated by DBP and FBS.

Seizure induced transient brain CT or MRI abnormalities following status epilepticus have previously been reported. However, focal transient imaging abnormalities involving hippocampus or mesial temporal lobe as a consequence of seizure are rare findings. We report 2 patients with transient mesial temporal abnormalities on MRI associated with partial seizure of temporal lobe origin. A 59-year-old man with a 4-month history of occasional epigastric rising sensation had developed frequent olfactory hallucination 7 days prior to presentation. On brain MRI, T2 signal was increased in the right mesial temporal region, and the lesion showed mild mass effects and partial enhancement after gadolinium injection. Interictal spikes were noted from right nasopharyngeal electrode, but there was no clinical or electrical evidence of status epilepticus during prolonged scalp/sphenoidal EEG monitoring. His seizures were successfully controlled by phenytoin. T2 high signal was markedly decreased and prior enhancement was no longer seen on brain MRI done 5 weeks later. A 33-year old woman with a 6 month history of occasional vacant staring and oral automatism with amnesia complained progressive memory impairment. Right amygdala and hippocampal head was enlarged and showed T2 high signal without contrast enhancement. EEG with sphenoidal electrodes showed right sphenoidal spikes. Her seizures were controlled by carbamazepine and brain MRI became unremarkable 6 weeks later. Suggested mechanisms and significance of the transient imaging abnormalities following seizures will be briefly reviewed.
