Plasma cell myelomas generally manifest as bone or soft-tissue tumors with variable mass effects, pain, and infiltrative behavior. Extramedullary involvement occurs most commonly in the spleen, liver, lymph nodes, and kidneys, but intracranial involvement in plasma cell myeloma is a rare extramedullary manifestation. These authors recently encountered a case of intracranial involvement of plasma cell myeloma. A 69-year-old man was hospitalized for headache and mental changes. Brain CT showed subdural hemorrhage caused by plasma cell myeloma. Plasma cell myeloma with intracranial involvement has poor prognosis, and the patient in this case died from acute complications, such as subdural hemorrhage. Based on this case report, it is suggested that more effective treatment regimens of plasma cell myeloma with intracranial involvement be developed. Moreover, a screening method and decision on the appropriate time for intracranial involvement are needed for plasma cell myeloma patients.

To estimate the influence of plasma copper and zinc concentration on infertility, we measured copper and zinc levels in plasma of 117 infertile women and 14 infertile men by atomic absorption spectrophotometry from January, 1987 through June, 1987 and the results were as follows. 1. The mean plasma copper level was significantly lower in infertile women than in fertile control women while mean plasma zinc level significantly higher in infertile women than in fertile control women. 2. A significant difference in the mean plasma level between infertile women with tubal and endometrial factor and normal controls was noted. 3. The mean level of copper in plasma of azoospermic patients was significantly higher than in fertile control subjects. 4. In fertile control and infertile women, no diurnal and menstrual cyclic variations in plasma zinc and copper levels were present, respectively. Also, there were no significant correlation between plasma zinc and copper levels in all studied group of subjects.

Background: Osteopontin (OPN) and carbonic anhydrase IX (CAIX), which are expressed on the surface of tumor cells, are associated with hypoxia during tumor development and progression. However, the roles of these proteins in the plasma of patients with non-small cell lung cancer (NSCLC) are poorly understood. Herein, we hypothesized that plasma OPN and CAIX levels could be used as diagnostic and prognostic tumor markers in patients with NSCLC. Methods: Fifty-three patients with NSCLC and 50 healthy control subjects were enrolled. We selected controls without malignancy and matched them with NSCLC patient cases according to age and gender. Blood samples were collected at the time of diagnosis; the plasma levels of OPN and CAIX were measured by enzyme-linked immunosorbent assays. Results: The plasma levels of OPN in the patients with NSCLC were significantly elevated as compared to those in the controls (p=0.016). However, there was no difference in the plasma level of CAIX between the NSCLC patients and controls. NSCLC patients with a distant metastasis had a remarkable increase in plasma OPN compared with patients without metastasis (p=0.026), but no such correlation was found for CAIX. There was no difference in overall survival rates according to the plasma level of OPN between the two groups (by Kaplan-Meier survival analysis). Conclusion: Plasma OPN levels were elevated in patients with NSCLC as compared with the controls, with greater elevation of OPN levels in the advanced stages of disease. Therefore, plasma OPN may have utility as a diagnostic, but not prognostic, biomarker of advanced NSCLC.

The aim of this study was to evaluate oriental medicine pattern identification in patients with stroke on the basis of plasma fibrinogen levels and platelet counts. 555 patients diagnosed with stroke between November 2006 and February 2010 were divided in several ways according to the plasma fibrinogen levels and platelet counts on admission. And comparative analysis of the distribution ratio of oriental medicine pattern identification was done between the groups. The mean value of the plasma fibrinogen levels of whole population was 449.18 mg/dL, and it was higher than normal range. The mean value of the platelet counts of whole population was 244.29 /mL, and it was lower but in normal range. Oriental medicine pattern identifications were not characteristic between groups divided according to the serum levels of fibrinogen and platelet counts. In this study, there was not significant correlation between Oriental medicine pattern identifications and the thrombotic factor like plasma fibrinogen levels and platelet counts. This study could be the steppingstone for the next study to develope the objective indicator for the Oriental medicine pattern identifications.

Erythropoietic activity in anemic Plasma of chronic posthemorrhagic anemic men was studied in rats after subcutaneous injection of anemic plasma. Anemic plasma was obtained from blood donors who sold their blood once or twice a week for one or two years to blood bank. Hemoglobin concentrations of 8 blood donors ranged between 4.6 and 8.4 gm/100 ml. Pooled plasma was treated by acidification-boiling method and adjusted to pH 7.5 by adding 0.1 N NaOH. 7ml/kg and 15ml/kg of anemic plasma filtrate was injected to 2 groups of rats respectively for 7 and 8 days. Hemoglobin concentrations, red blood cell counts and reticulocyte counts were observed before and after injection of anemic plasma and no change was induced by the injection. Subsequently, it was concluded that there was no erythropoietin of high titer in the plasma of chronic post-hemorrhagic anemic men.

Objectives : This study was performed to investigate the effects of Foeniculum Vulgare(FV) extract on the anti-inflammatory of lipopolysaccharide(LPS) exposed rats. Methods : We divided LPS exposed Sprague-Dawley rats into 4 groups. They were control group, feed with 100 mg/kg, 200 mg/kg, 300 mg/kg FV groups. They were administered for 6 weeks. We measured the concentration of plasma interleukin-1${\beta}$(IL-1${\beta}$), plasma interleukin-6(IL-6), plasma tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), plasma interleukin-10(IL-10), the concentration of liver IL-1${\beta}$, IL-6, TNF-${\alpha}$ and IL-10. Results : 1. Plasma IL-1${\beta}$, plasma IL-6 and plasma TNF-${\alpha}$ concentration increased rapidly at 2hours after LPS injection and maintained high levels at 5hours after LPS injection. The concentration of these cytokines in the FV extract groups showed lower values than control group(P<0.05). 2. The concentration of Plasma IL-10 in FV extract groups showed higher values than control group at all times(P<0.05). 3. The concentration of liver IL-1${\beta}$ and IL-6 in FV extract groups showed lower values than control group(P<0.05). The concentration of liver TNF-${\alpha}$ in FV extract groups showed a tendency to decrease and that of liver IL-10 in FV extract groups showed a tendency to increase; however, these values showed no significantly different. Conclusions : In inflammatory response by LPS derivation, the FV gives positive effect.
