Background: This study was aimed to compare the analgesic effect and side effects of morphine- bupivacaine mixture with those of fentanyl-bupivacaine mixture after Cesarean section. Methods: Eighty patients who were taken continuous epidural catheterization after Cesarean section were divided into two groups. In group 1 (N=40) the mixture of 1% lidocaine 10 ml and morphine 1mg was firstly injected via epidural catheter, and then two day infusor (Baxter(R)) which contained the mixture of 0.15% bupivacaine 100 ml and morphine 6mg was connected to epidural catheter. In group 2 (N=40) the mixture of 1% lidocaine 10 ml and fentanyl 100 mcg was firstly injected via epidural catheter, and then two day infusor (Baxter(R)) which contained the mixture of 0.15% bupivacaine 100 ml and fentanyl 850 mcg was connected to epidural catheter. Mean arterial pressure (MAP) and heart rate (HR) were checked preoperatively, and at post-injection 10, 20, 30 and 60 minutes. The visual analogue scale (VAS) was checked at postoperative 1/2, 1, 6, 12, 24 and 48 hours. The side effects of epidural analgesia were evaluated. Results: In group 2 MAP was significantly decreased at post-injection 20 minute. VAS was significantly increased at post-injection 1/2 and 1 hour in group 1. The most frequent side effect was pruritus in both groups. Conclusions: The first bolus injection of the mixture of 1% lidocaine 10 ml and fentanyl 100 mcg has more rapid analgegic effect than the mixture of 1% lidocaine 10 ml and morphine 2 mg, but because of shorter duration of action of fentanyl it seems to be better to increase the dosage of fentanyl or replace fentanyl by morphine for more effective epidural analgesia after Cesarean section.

The presence of volcano-shaped pseudomembrane(PM) formations above the inflamed mucosa has been referred to as the unique biopsy criterion of the pseudomembranous colitis, but PM might be lost during the bowel preparation, and such loss leads pathologists to erroneous interpretations of the endoscopic biopsy specimens. The purpose of this paper is to identify the additional diagnostic clue other than PM among various histologic features in pseudomembranous colitis. We reviewed sigmoidoscopic biopsy specimens from 13 cases of antibiotics-associated pseudomembranous colitis which was confirmed to reveal characteristic PM by endoscopy aside from the clinical history of antibiotics administration. The cases were divided into two groups: the presence of PM (n=7) and its absence (n=6). Both groups showed basically identical histology, which included features of glandular distension, epithelial necrosis, crypt abscess, regenerative glands and mucous plug within the necrotic/dilated glands. Mucous plugs within the necrotic/ dilated glands were found in all cases and seemed to be the most characteristic microscopic feature. Ten cases of resected chronic ulcerative colitis in the active stage were compared for a differential diagnosis of crypt abscess-associated mucosal change. None of them revealed necrotic gland with mucous plugs, although crypt abscess formation was common in both conditions. We conclude that presence of mucous plugs in the dilated/necrotic glands is a useful diagnostic clue even though the biopsy specimens fail to demonstrate PM.

This study was conducted to evaluate the effect of PTSD on memory funtion and hippocampal volume, and to identify major variables correlated to hippocampal volume and memory function. Thirty four Vietnam veterans were collected for this study, among whom eighteen were PTSD patients and sixteen were combat control subjects. The author used Impact of Event Scale(IES), Combat Exposure Scale(CES), Hamilton Depression Rating Scale(HDRS) and Beck Depression Inventory(BDI). Korea Memory Assessment Scale(K-MAS) was assessed for memory function. Magnetic resonance imaging(MRI) was used to measure hippocampal volume. There were significant differences between PTSD and Non-PTSD veterans in IES, HDRS and BDI. Significant difference was found in verbal memory and total memory of K-MAS between PTSD and Non-PTSD veterans. There was significant difference in hippocampal volume between PTSD and Non-PTSD veterans. Short term memory, verbal memory and total memory were positively correlated to hippocampal volume. Hippocampal volume was negatively correlated to IES, HDRS, and BDI. These results suggest that PTSD severity be associated with hippocampal atrophy and memory dysfunction. Reduced or smaller hippocampal volume may be preexisting risk factor for stress exposure or the development of PTSD on combat exposure.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

OBJECTIVES: The purpose of this study was to investigate the risk factors in veterans for posttraumatic stress disorder and to find the correlation between the disorder and the characteristics of the variables. METHODS: We compared the risk factors in veterans between 40 diagnosed PTSD patients and 78 controls, using psychiatric by psychiatrists and measurement instruments such as CES, Mississippi scale, and BDI RESULTS: 1) There was statistically significant difference in prevalence on pre-military factor with regard to age at recruit(p<0.05) 2) PTSD on military factor was closely correlated with CES score(p<0.05) 3) There was statistically significant difference in PTSD on post-military factor with regard to occupation(p<0.05) 4) Scores of Mississippi scale, and BDI in PTSD were higher than those in control subjects(p<0.05, p<0.05) CONCLUSION: This results suggest that the likehood of developing PTSD in veterans depends on pre-military and post-military factors in addition to features of the trauma itself. Age of entry into the military, CES score, and occupation had statistically significant relationships with PTSD.

CT was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any otherclassical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically andhistologically. The results were as follows; 1. Age distribution of the cases was 15 males and 16 females withpeak age of 6th decade in males and 4th decade in females. 2. Metastatic lesions were multiple in 18 cases andsingle in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Markededematous low densities with relatively small nodular high densities in precontrast scan and variable contrastenhancement of the nodular densities were the most frequent CT findings. 4. No specific characterstics accordingto the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.
