BACKGROUND: Total intravenous anesthesia with propofol can cause respiratory depression and apnea especially during induction of anesthesia. To study the possibility of reversal of respiratory depression during anesthesia with propofol, pretreated with nabuphine or not, the respiratory effects of doxapram to spontaneously ventilating patients were investigated. METHODS: Patients were divided into 4 groups - saline-propofol-saline group (SPS), saline-propofol- doxapram group (SPD), nalbuphine-propofol-saline group (NPS), and nalbuphine-propofol-doxapram group (NPD). After saline or nalbuphine pretreatment, anesthesia was induced with propofol and then doxapram or saline was intravenously injected. Apneic time interval, blood pressure, heart rate, respiratory rate, minute ventilation, end tidal CO2 partial pressure and oxygen saturation were measured in every minutes during induction of anesthesia. Percent changes of each values were compared. RESULTS: There is no differences in apneic time intervals in each groups. The percent change of first minute ventilation in SPD group after doxapram injection unchanged significantly compared with those depressions of SPS, NPS and NPD group (p<0.05). Respiratory rates increased in SPD and SPS groups after laryngeal mask insertion. There is no differences in minute ventilation, respiratory rate and end-tidal CO2 concentration between nalbuphine pretreated groups regardless of doxapram injection. CONCLUSIONS: Doxapram has effect in increasing minute ventilation after propofol induction within first few minutes, but it cannot reverse respiratory depression during propofol induction pretreated with nalbuphine.

Vibrio vulnificus infection is one of the most fatal diseases in Korea. This study was undertaken to determine the cellular fatty acid (CFA) compositions of ninety-five clinical strains of V. vulnificus isolated from Korea during 1985-1995. We compared these results with the CFA profile of V. vulnificus in the Microbial Identification System (MIS) (CLIN library version 3.9; Microbial ID Inc., Newark, Del.), and also evaluated the MIS ability to identify V. vulnificus. Subgrouping of V. vulnificus by CFA analysis was performed and its results were compared with those of serotyping. Most of the CFAs in V. vulnificus strains were similar to the CFA profile of V. vulnificus in the MIS, but some distinctive differences were observed. First, means of two major CFAs, 16:0 and 16:1w7c, were 22.16% and 18.26% in this study, but 23.52% and 25.44% in the MIS respectively. Second, all isolates had 11:Oiso3OH, which was not present in the MIS. Eighty-five strains (89.5%) disclosed the first choice identification of V. vulnificus by the MIS, but only two strains (2.1%) were identified with SI values of 0.6. Remaining ten strains (10.5%) showed 'NO MATCH' results. Cluster analysis of CFA could separate V. vulnificus into nine subgroups, and predominant subgroups were subgroup VII (45 strains) and V (36 strains). There was heterogeny between subgroups by CFA and serotypes of V. vulnificus. The strains of 04 serotype which accounted for 80% (76/95) of the isolates were distributed into six different subgroups such as VII (40 strains), V (27 strains), III (4 strains), I (2 strains) and VI (1 strain). These showed that V. vulnificus strains isolated from Korea had different characteristics in the CFA composition in comparison with the MIS V. vulnificus library. Subgrouping by the CFA analysis might be a useful tool for the epidemiological study of V. vulnificus infection in Korea.

To evaluate the typical appearance and the influence in the image interpretation of the metallic artifact which is known as one of the patient-related field artifacts, we analysed the magnetic resonance (MR) images of 40 patients (the total number of metallic materials were 45) acquired at MR 1.5T unit. All patients were screened for the presence of metal. The metallic implants were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts produced by metallic objects can be seen on MRI as the focal loss of signal and/or the local distortion of the image. Regardless of their ferromagnetic properties, metallic implants created regional artifacts in their images. Ferromagnetic materials, such as a lead fragment, showed severe artifacts and nonferromagnetic metals showed mild to moderate artifacts. The conspicuity of artifact was related tot he composition, mass, shape, orientation, and the location of the metallic objects in the body. Under high magnetic field strength, there were no significant differences between the various pulse sequences. Artifacts are particularly prominent on gradient-echo images. Our findings indicate that MR imaging of patients with standard nonferromagnetic metallic materials can be successfully performed and usefully interpretated.

The distribution of glycogen, polysaccharide, mucopolysaccharide, lipid and nucleic acid has been studied in Echinorhynchus gadi(Acanthocephala). The results were summarized as follows: Glycogen and polysaccharide was demonstrated by Bauer PAS reaction technique and was found in fertilization membrane in ovum, central nuclear mass in acanthor and lemnisci, hypodermis in cystacanth. Mucopolysaccharide was demonstrated by Mowry alcian blue staining technique and was found in outer membrane, fibrillar coat, fertilization membrane and inner membrane in acanthocephalan ova. Lipid was demonstrated by Smith Nile blue stain and Lison Sudan black B staining technique and was found roughly parallel to that of polysaccharide. Nucleic acid was demonstrated by Rosenbeck Feulgen reaction, Taft methylgreen-pyronin stain and Diengdoh acridine orange staining technique and found in central nuclear mass in acanthor, also, was found in lemnisci, proboscis and hypodermis in cystacanth.

The authors underwent the serum lipid study, involving the lipoprotein fraction, and the HDL-cholesterol mean values in normal Korean adults visited to Hanyang University Hospital, and also compared with the previously reported serum lipid studies. The results are as follows; 1) The mean values of triglyceride, total cholesterol, and phospholipid were 103.3+/-17.1mg%, 188.9+/-18.2mg%, and 196.7+/-19.8mg%, respectively. 2) Compared with the past 7 years triglyceride showed increasing tendency with significance, and cholesterol and phospholipid showed slightly increasing tendency. 3) In the serum lipoprotein fraction, the mean values of alpha-lipoprotein, pre-beta-lipoprotein, and beta-lipoprotein were 37.2+/-5.9%, 16.0+/-4.2%, and 48.6+/-5.2%, respectively. 4) Compared with the past 10 years, the alpha-, and pre-beta-lipoprotein showed increasing tendency, meanwhile, beta-lipoprotein revealed decreasing tendency. 5) The mean value of HDL-cholesterol was 52.3+/-14.6mg%, and the ratio of HDL-cholesterol to total cholesterol(HDL-cholesterol/total cholesterol) was 28.2+/-7.9. 6) Compared with the past 2 years, HDL-cholesterol level showed slightly increasing tendency.
