OBJECTIVES: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. METHODS: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. RESULTS: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. CONCLUSION: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

Respiratory distress syndrome (RDS) in the newborn infants remains a major cause of mortality and morbidity in the newborn period despite much improvements in neonatal intensive care and artificial ventilatory techniques. Gastric fluid was obtained from 151 patients within 6 hours after delivery. The sensitivity, specificity, and predictive value of the simple shake test (133 cases) and stable microbubble rating (SMR) test (151 cases) were assessed in the diagnosis of RDS, as well as the relation between both tests and RDS. We carried out both tests of on gastric aspirates all newborn who admitted to NICU of Presbyterian Medical Center from June 1991 to August 1992. The results were summarized as follows: 1) Among the total 151 cases, RDS were found in 41 cases(27.2%). 2) RDS occurence rate of the simple shake test was 11/11 in 0 group, 17/26 in +1 group, 8/28 in +2 group, 2/41 in +3 group, and 2/27 in +4 group. RDS occurence rate was high the 0 and +1 group. 3) RDS occurence rate of the SMR test was 4/4 in very weak group, 32/36 in weak group, 1/33 in medium group, and 4/78 in strong group. RDS occurence rate was high in the very weak and weak group. 4) Among the positive group of the SMR test 95 cases, positive group of the shake test were found in 87 cases. Among negative group of the SMR test 38 cases, negative of the shake test were found in 29 cases (correlation coefficient=0.763). 5) Sensitivity of the shake test and SMR test were 70%, 87.8% respectively. Specificity of the shake test and SMR test were 93.3%, 96.4% respectively. Positive predictability were 75.7%, 90% respectively and negative predictability were 87.5%, 95.5% respectively. The shake test, as Well as SMR test, has significant value to diagnosis of the RDS. We predict RDS occurence rate of the SMR test was significantly higher than shake test.

PURPOSE: Receptors for the Fc of IgG(FcvR) and a beta2 integrin molecule, CD11c/CD18 are important in clearance of microbes by granulocytes. We performed an in vitro study on the effect of recombinant human granulocyte colony-stimulating factor(rhG-CSF), or granulocyte-macrophage colony-stimulating factor(rhGM-CSF) on the expression of Fc R II, Fc R III, CD11c and CD18 and respiratory burst function of granulocytes. METHODS: Peripheral blood was collected from six healthy adults. The isolated granulocytes were stimulated with rhG-CSF, 250mg/mL, rhGM-CSF, 100ng/mL or both of them for 1, 3, 9, 24, and 48 hours. Using flow cytometry, we compared the expression of the Fc R II, Fc R III, CD11c and CD18 of granulocytes before and after stimulation. We also the studied respiratory burst of granulocytes with chemiluminescence assay. RESULTS: Fc R II and CD18 expression were not changed significantly after stimulation. Fc R III expression was decreased significantly after stimulation with rhG-CSF, rhGM-CSF, or both of them. CD11c expression was increased initially but was found to decrease significantly after 9 hours of stimulation. Granulocytes treated with rhG-CSF, rhGM-CSF, or both displayed enhanced respiratory burst. Our results suggest that exposure of granulocyte to growth factor results in granulocyte activation. CONCLUSION: We have shown that rhG-CSF and rhGM-CSF resulted in an activation of peripheral blood granulocytes immunophenotypically and functionally.
