Because central venous O2 saturation (superior vena cava, ScvO2) can be monitored with less risk of the patients than mixed venous O2 saturation (pulmonary artery, SvO2), there have been studies to see if ScvO2 could replace SvO2. But previous studies showed that these two measurements were correlated but "not interchangeable. Therefore the authors compared right atrial C#b saturation (SraO2) with S vO2 over a wide range of cardiorespiratory status including control, hemorrhage, resuscitation, and hypoxia in anesthetized cats. We performed thoracotomy and inserted cannulae directly into the right atrium and the pulmonary artery. Blood sampling were obtained synchronously through the cannulae and tested immediately. The correlation coefficients in control, hemorrhage, resuscitation, and hypoxia groups were 0.876, 0.794, 0.946, 0.948 respectively and the two measurements in each group showed statistically significant correlations (p<0.05). But the biases of the two measurements in each group were 0.11+/-2.9, 0.35+/-4.2, -0.55+/-3.2, 0.23+/-4.2 respectively and the limits of agreement ( 2 standard deviation) in all groups exceeded permissible (5%) to conclude that the two measurements were in agreement. Thus, we reached the conclusion that the absolute values of SraO2, though not being sufficiently identical to S vO2 to calculate O2 uptake or pulmonary shunt precisely, can reflect the S vO2 trend following the O2 supply / demand change. Further clinical studies are needed.

PURPOSE: Hypertension accelerates the progression of chronic renal disease, whether it results from, or causes, the renal disease. Therefore, the control of hypertension is one of the important factors that retard the rate of renal deterioration. We compared the effects of different antihypertensive agents on renal function and glomerular morphology in subtotal nephrectomized rats. MATERIALS AND METHODS: After induction of chronic renal failure with 5/6 nephrectomy, the rats were divided into three groups; control group (Group C), enalapril group (Group E), and nicardipine group (Group N). Systolic blood pressure was measured by tail cuff method every 4 weeks until 12 weeks after nephrectomy. At 12 weeks after nephrectomy, all rats were placed in metabolic cages for 24 hour urine collections to measure urinary protein and creatinine excretion. After urine collection and blood sampling for serum creatinine, all rats were sacrificed. The renal tissue was processed for morphometric study with light microscope and electron microscope. RESULTS: 1. The blood pressure of Group C increased progressively, but both enalapril and nicardipine prevented the development of hypertension, and the two drugs were equally effective in maintaining normal blood pressure throughout the study. 2. Twenty-four hour urinary protein excretion was lower in Group E compared to Group C and Group N. 3. Mesangial expansion score in both treated groups were significantly lower than the control group. Mean glomerular volume in Group E was significantly reduced compared to Group C and Group N. There was no significant difference in mean glomerular volume between Group C and Group N. 4. There was no significant difference in podocyte structural changes, estimated by filtration slit length density, among control, enalapril and nicardipine treated groups. CONCLUSION: Control of hypertension with enalapril or nicardipine afforded considerable protection from mesangial expansion in the rat remnant kidney model. But protein excretion and glomerular growth were significantly reduced in Group E compared to Group N. There was no significant difference in podocyte structural changes among the 3 groups.

Various probiotic strains have been reported to affect emotional behavior. However, the underlying mechanisms by which specific probiotic strains change brain function are not clearly understood. Here, we report that extracellular vesicles derived from Lactobacillus paracasei (Lpc-EV) have an ability to produce genome-wide changes against glucocorticoid (GC)-induced transcriptional responses in HT22 hippocampal neuronal cells. Genome-wide analysis using microarray assay followed by Rank-Rank Hypergeometric Overlap (RRHO) method leads to identify the top 20%-ranked 1,754 genes up- or down-regulated following GC treatment and their altered expressions are reversed by Lpc-EV in HT22 cells. Serial k-means clustering combined with Gene Ontology enrichment analyses indicate that the identified genes can be grouped into multiple functional clusters that contain functional modules of “responses to stress or steroid hormones”, “histone modification”, and “regulating MAPK signaling pathways”. While all the selected genes respond to GC and Lpc-EV at certain levels, the present study focuses on the clusters that contain Mkp-1, Fkbp5, and Mecp2, the genes characterized to respond to GC and Lpc-EV in opposite directions in HT22 cells. A translational study indicates that the expression levels of Mkp-1, Fkbp5, and Mecp2 are changed in the hippocampus of mice exposed to chronic stress in the same directions as those following GC treatment in HT22 cells, whereas Lpc-EV treatment restored stress-induced changes of those factors, and alleviated stress-induced depressive-like behavior. These results suggest that Lpc-EV cargo contains bioactive components that directly induce genome-wide transcriptional responses against GC-induced transcriptional and behavioral changes.

Seizure associated with antiemetics is rare. We report seizure associated with a 5-HT3 receptor antagonist in a 38 years old female. The patient underwent ureterorenoscopic lithotripsy due to left upper ureter stone. After operation, the patient complained of nausea in the postanesthetic recovery unit. In order to subside symptom, the patient was administrated 5-HT3 receptor antagonist, palonosetron, 0.075 mg intravenously. Shortly after administration of that, the patient developed generalized tonic-clonic seizures. The symptom was subsided after midazolam and thiopental sodium were injected. But 40 minutes later, seizure recurred and subsided with midazolam again. The patient recovered completely without any specific sequelae.

Gastric ulcer bleeding is commonly encountered in emergency situations for gastroenterologist. Usually depth of gastric ulcer does not exceed the muscle layer. We report a case of a 67-year-old male with massive gastric ulcer bleeding caused by direct connection to the splenic artery. Bleeding control was not effectively performed by endoscopy due to massive bleeding with unstable vital sign. Angiography for embolization was performed. Active extravasation of contrast agents at the splenic artery stenosis was noted on splenic arteriogram. Bleeding stopped after embolization with histoacryl and lipiodol was successfully performed. After 1 month, complete ulcer healing was confirmed by follow up endoscopy. There was no evidence of invasive disease on biopsy.
