This clinical study is based on review of records of 87 patients with postoperative adhesive intestinal obstruction who were managed at the Department of Surgery of Dongbu City Hospital during 5 years from September, 1992 to August, 1997. The results of study were as follows: 1) The most prevalent age group was 5th decade(44.8%) and male to female ratio was 1.7:1. 2) The previous operations were operation for appendicitis(32.2%), operations for peritonitis due to peptic ulcer perforation(24.1%), gynecologic operations(13.8%), operation for gastric malignancy(8.1%). 3) The mean value of duration between previous operations and postoperative adhsive intestinal obstruction was 36 months and the mean value of duration of symptoms was two days. 4) 42(49.2%) of 87 patients were admitted under 24 hours after onset of symptoms. 5) The chief complaints on admission were abdominal pain(98.8%), vomiting(81.6%), abdominal distension(78.2%), failure to flatus(55.2%). 6) 23 cases(45.1%) of 51 cases having one or more abnormal physical and laboratory finding(fever, abdominal tenderness, abscence of defecation or gas out, or leukocytosis) were operated, and 5 cases(13.9%) of 36 cases having no physical finding were operated (p value < 0.05). 7) Emergency operation was performed in 9 cases, elective operation was performed in 19 cases which had deteriorating clinical course despite of conservative management for 48 hours, and conservative treatement was performed in 59 cases. 8) The postoperative complications were observed in 6 cases and the most common complication was wound infection(14.3%). In conclusions, The longer symptom duration and the longer interval between previous operation and onset of symptoms, the higer probability of surgical treatment is expected. The need for surgical treatment was increased acording the number of physical and laboratory findings(fever, abdominal tenderness, abscence of defecation or gas out, or leukocytosis). For the cases which have unimproving and deteriorating clinical course despite of conservative management for 72 hours, surgical operation shoud be considered.

PURPOSE: In adriamycin(ADR)-induced cardiomyopathy, several different mechanisms are suggested. However, little information is available regarding the role of apoptosis. In the present study, we examined the induction of apoptosis on ADR treatment and anti-apoptotic effects of probucol, a lipid-lowering drug, and we also studied the changes of bcl-2 expression in order to see the molecular mechanisms underlying the effect of probucol. METHODS: Cardiac myocytes were isolated from 3-day-old rats, and cultured in low(1 pM) or high doses(10pM) of ADR for 24 hours. Probucol(50 pM) was added 30 minutes before ADR administration. Apoptosis was determined by TUNEL staining, and bcl-2 expression was estimated by immunocytochemistry. RESULTS: The number of TUNEL-positive cells significantly increased in both groups treated with ADR. However, anti-apoptotic effect of probucol was evident only in low dose. In addition, the expression of bcl-2 was significantly increased only in the low-dose ADR treatment group and its expression was inhibited by pretreatment of probucol. CONCLUSION: These results suggest that apoptosis might play an important role in ADR-induced cardiotoxicity, and ADR-induced apoptosis was partially prevented by pretreatment of probucol. And ADR-induced apoptosis was not related with depression of bcl-2. Additionally, inhibition of bcl-2 gene expression of low-dose ADR treatment group by probucol suggests that another cell survival mechanism could be implicated in the action of probucol.

When the non-union gap in a long bone is more than half of the diameter of the bone at that level, it presents a significant challenge to traditional bone grafting technique. Even if there are several good ways for this problem, such as shortening, traditional various bone grafting, electrical stimulation and free vascularized bone graft, most of these techniques have some difficulties to maintain the stability of fracture post-operatively, and we have to keep their extremities into a cast or external fixator so long. So we have attempted to treat the large osseus gap non-union in long bone with fixation of heavy duty or condylar plate on one side of fracture for fracture stability, a long tibial corticocancellous strut graft on the other side of fracture for fracture stability and rapid bony union, and extensive cancellous chip bone graft between the plate and tibial graft to enhance the bony union. We have experienced 9 cases of large osseus gap non-union in long bone with this technique from March 1981 to September 1986 at the department of orthopaedic surgery, St. Mary's hospital, Catholic University Medical College. 1. Their, 7 males and 2 females, average age was 38 years old, with a range of 24 to 53 years old. The distribution of the involved bone was 6 femur, 2 humerus, 1 radius and ulna with 1.4 years of average duration of non-union, ranged from 7 months to 2.4 years. The average gap from normal bone to normal bone was 4.8cm, with a range of 2.7cm to 7.4cm. The average number of previous surgical procedures was 4, with a range of 2 to 7. Four of the nine patients had quiescent osteomyelitis. 2. Post-operative immobilization with splint or cast was applied for 6 weeks for upper extremity and 8 weeks for lower extremity followed by active R.O.M. exercise and non-weight bearing crutch walking. 3. Five of the nine cases(55.6%) had completely bony union. This occured on an average 8 months post-operatively and was faster in the forearm bones and femur than in the humerus. An additional cancellous bone graft was done in two. But other two of the patients had subsequent amputation because of recurrent and uneontrollable osteomyelitis stirred up by the surgery. 4. This procedures was proved to be one of valuable adjuvant method in treatmqnt of large osseous gap non-union of long bones.

BACKGROUND/AIMS: There is considerable variance in individual susceptibility to hepato-toxic effects of ethanol as evidenced by the finding that only about 10-20% of alcoholics develop alcoholic liver cirrhosis. The aims of this study were, 1) to get the data on the genetic polymorphisms of three major ethanol-metabolizing enzymes (ADH, CYP2E1, ALDH) in normal Korean adults, and to search for the specific genotypes influencing alcohol drinking behavior by the comparison of allele frequencies between healthy control group and heavy drinker group with or without liver disease, 2) to investigate the influence of the genetic polymorphisms of these enzymes on the susceptibility to alcoholic liver disease by the comparison of allele frequencies between heavy drinker group without liver disease and alcoholic liver cirrhosis group. METHODS: Healthy control group included 53 healthy males in military service without evidence of liver disease or alcoholism. Heavy drinker group without liver cirrhosis included 29 males who had been drinking 80g or more of alcohol daily for more than ten years but did not have any clinical evidence of liver disease. Alcoholic cirrhosis group included 43 male patients who had drunk 80g or more of alcohol daily for more than ten years and had clinical evidences of overt cirrhosis. Subjects with hepatitis B surface antigen or anti-hepatitis C antibody were excluded. Genotypes of the three enzymes were determined by PCR (polymerase chain reaction) and restriction fragment length polymorphism (RFLP) with genomic DNAs extracted from peripheral leukocytes. RESULTS: 1) In healthy Korean males, allele frequency of ADH22, ADH31, CYP2E1 c2 and ALDH22 was 81%, 94%, 30% and 14%, respectively. 2) The absence of ALDH22 or CYP2E1 c2 allele were significant risk factors for being a heavy drinker (odds ratio,' 0.09, 0.42, respectively). 3) Although it was not associated with the polymorphism of each ethanol-metabolizing enzymes, the susceptibility to alcoholic liver cirrhosis was significantly associated with combined genotypes of ADH2(22) & ADH3(1+1)& CYP2E1 B or C. COMCLUSION: Genetic polymorphisms of ethanol-metabolizing enzyrnes are significantly associated with the suseptability to alcoholic liver disease as well as alcohol drinking behavior.

OBJECTIVEs: Cytogenetic investigations were carried out on 770 women with primary (n=560) and secondary amenorrhea (n=210) to determine the frequency of chromosomal or genetic causes of amenorrhea. MATERIALS AND METHODS: In 770 women with primary amenorrhea (n=560) and secondary amenorrhea (n=210), chromosomal analysis were performed. RESULTS: 1) The most prevalent age group is 16-20 years of age group with primary amenorrhea and 26-30 years of age group with secondary amenorrhea. 2) Out of 560 cases of primary amenorrhea, 343 cases (61.3%) had the normal chromosome constitution and 217 cases (38.7%) had the abnormal chromosome constitution including 46,XY. 3) In 217 cases of abnormal chromosome of primary amenorrhea, 57 cases (26.3%) had 45,X and 34 cases (15.8%) had the 46,XY, 24 cases (11.0%) had 45,X/46,X,i (Xq), 23 cases (10.6%) had 45,X/46,X,+mar and 14 cases (6.6%) had 45,X/46,XY. 4) Out of 210 cases of secondary amenorrhea, 181 cases (86.2%) had the normal chromosome constitution and 29 cases (13.8%) had 45,X/46,XX. CONCLUSION: High percentage of chromosomal abnormalities was diagnosed in primary amenorrhea and most of them were sex chromosome anomalies. In secondary amenorrhea, the prevalence was lower than primary amenorrhea, so a preselection of patients with secondary amenorrhea for cytogenetic investigations seems to be necessary.

Agrobacterium tumefaciens induces cancerous growths called crown galls at wound sites on dicotyledonous plants. A large plasmid called T1 plasmid is responsible for virulence. Upon tumor induction, part of the plasmid, termed T-DNA, becomes integrated into plant genome and its genetic sequences are expressed. These properties allow T1 plasmids to be used as gene vectors in plants. Several in vitro methods for the transfer of T1 plasmid into plant cell have been developed. One of them is the treatment of bacterial spheroplasts and plant protoplasts mixture with polyethylene glycol that is generally used as fusogen in cell-to-cell fusion. Several workers investigated the interaction of bacterial spheroplasts with plant protoplasts in the presence of polyethylene glycol and suggested that the interaction is not fusion but endocytosis. In this report we observed the interaction of Agrobacterium tumefaciens spheroplasts with Nicotiana tabacum protoplasts by electron microscope. Agrobacterium tumefaciens spheroplasts with Nicotiana tabacum protoplasts were prepared and mixed in the presence of polyethylene glycol and high pH-high Ca²⁺ buffer. Then the interaction of the spheroplasts with the protoplasts was examined by transmission electron microscope. After the treatment of polyethylene glycol the spheroplasts adhered to the surface of the protoplasts and then they were engulfed by the protoplasts. After the high pH-high Ca²⁺ buffer treatment the engulfed spheroplasts lost their cell integrity. No fusion process was observed. Thus all these observation suggest that the introduction process of Agrobacterium tumefaciens spheroplasts into Nicotiana tabacum protoplasts with the aid of polyethylene glycol is endocytosis.
