Rectus sheath hematoma is an uncommon entity of the anterior abdominal wall and an unusual cause of painful abdominal mass. Rectus sheath hematoma have been in association with trauma, infections, debilitating disease, collagen vascular disease, pregnancy. and the puerperium. Sudden disruption of a deep epigastric vessel may result in an abdominal wall hematoma, which depending upon its location and size, can produce symptoms and clinical findings compatible with a variety of acute intra-abdominal conditions. Such hematoma are infrequently encountered and early accurate diagnosis could prevent surgical intervention. Unfortunately, the clinical manifestations of rectus muscle hematoma are sometimes so dramatic that laparotomy is performed under the belief that intra-abdominal pathology is present. The diagnosis was confirmed at surgery in both patient. We present two cases of rectus sheath hematoma which were diagnosed by clinical & ultrasound examination preoperatively.

Industrial glues, known as 'Bonds' in Korea, contain many kinds of organic solvents, and glue sniffing of youths became one of the social problems in Korea. Mixed exposures to solvents by glue sniffing may induce chronic toxicities different from those by exposures to solvents of single component. To test effects of the glue sniffing on weight gain or central nervous system, two groups of 20 male Sprague-Dawley rats were exposed to air(control group) or vapors of the glues to narcotic status(exposed group), and weight check, tail flick test, hot plate test, rotarod treadmill test were done on the 14th, 24th, 36th, 45th, 53rd, 86th, 102nd, 117th, 134th and 151st days after the first exposure. On the 188th day, their brains were excised and examined by a pathologist. Weight gain, controlled against time change, showed significant difference between the groups, but response times in tail flick test, hot plate tests, and rotarod treadmill test didn't. In pathological examination with blind method, no macroscopic or microscopic difference were found between the two groups. These results suggests that organic lesion in central nervous system may not ensue glue sniffing, but, before firm conclusion, more studies in various exposure conditions should be followed.

One, two, six and ten week old Sprague-Dawley rats were exposed to carbon monoxide at 3,700 ppm for 30 minutes, and carboxyhemoglobin was measured immediateley, 5, 30, 60, 90, 120 minutes after the exposure. In each time after the exposure, the means of the carboxyhemoglobin levels were "compared among the week age groups. The regression analysis was done using the natural logarithm. of the carboxyhemoglobin concentration as a dependent variable and the time after the exposure. as an independent vaiable. From the regression equation, the half lives of the carboxyhemoglobin were calculated. The one week old rats showed significantly higher carboxyhemoglobin level than other week age rats in the entire time after the exposure. The corrected carboxyhemoglobin concentration calculated by subtracting the normal carboxyhemoglobin level from the me cured carboxyhemoglobin at each age group, showed no uniform differences.

This article is being retracted as a part of the manuscript was a 'duplicate publication' from an earlier publication.

A controlled study was carried out in 50 patients with perennial bronchial asthma to assess the efficacy and safety of budesonide turbuhaler. Subjects have suffered from cough, wheezing, dyspnea and chest tightness and showed either 15% of reversibility in FEV after bronchodilator inhalation or airway hyperresponsiveness to methacholine(PC20 < or = 25mg/ml.) Patients were randomized to treatment with budesonide turbuhaler or terbutaline turbuhaler for 8 weeks after 2 weeks of run-in period. Budesonide turbuhaler was effective for cough, wheezing, dyspnea and chest tightness. It improved peak expiratory flow rate and FEV1. Budesonide turbuhaler was tolerated well and the laboratory tests showed no abnormality. It is suggested that budesonide turbuhaler is effective and safe in the management of bronchial asthma.

In order to understand the role of mec regulator genes in the evolution of methicillin-resistant S. aureus (MRSA), the distribution of the mec regulator genes among the 66 clinical isolates of MRSA was analysed. And also the correlation between gene mutation and degree of phenotypic expression of resistance was studied. Fifty strains carried whole mec regulator region, while the mecI gene and nearly half of the 3'-end of the mecR#l gene were deleted in fifteen strains. The mecRl MS gene was detected among all of the mecA carried strains, but the mecRl PB gene was carried by 77% of the MRSA strains. At least a portion of the 5'-end region of the mecRl gene was carried by all MRSA strains tested. Forty-seven strains were finally confirmed to have mecI gene and each mecI gene of above strains was sequenced for identification of the relationship between repressor function of mecI gene on mecA transcription and MIC level of methicillin. Point mutations were detected in 11 strains of 47 strains. In 8 strains, there was one nucleotide substitution (C to T at position 202) that produced a new termination codon at position 201. In 3 strains, one nucleotide substitution from G to T at position 43 caused an amino acid substitution from Val to Phe. The MIC of methicillin of strains carrying mutated mecI genes ranged 256 ug/ ml to 1024 ug/ml. Transcription level of amplified cDNA corresponding to mecA was determined by the method of RT-PCR of extracted RNA. Total RNA was extracted from two strains with mutated mecI gene and a strain with intact mecI gene. Deletional loss or the mutational inactivation of the mecI gene did not affect the level of mecA transcription. Role of mecI gene as a strong repressor function on mecA gene seemed to be skeptical.
