A novel bacteriophage, designated as VPP97, that infects the strains of Vibiro parahaemolyticus (hallophilic, Gram-negative bacterium) isolated most commonly from marine environments, has been discovered, and several of its properties have been determined. The plaques were clear and sized 0.6-1.0 mm in diameter. The virion forms a single band on 70% sucrose gradient and p1.50 CsC1 gradient by sucrose gradient centrifugation and CsCI gradient centrifugation respectively. It has a hexagonal head and a relatively long tail, as shown by electron microscopy. Vibrio alginolyticus, Vibrio fluvialis and Vibrio furnissii were also sensitive to this phage It was almost totally inactivated at 70 degree C and at pH below 5 or over 10. The nucleic acid of VPP97 is composed of DNA. The VPP97 had 9 specific structural proteins sized between 21.5 kDa and 97.4 kDa on SDS-PAGE. When V. parahaemolyticus cultures were treated with either phage VPP97 or one of the several antibiotics for 2 hours, the viable number of V. parahaemolyticus treated with the phage VPP97 is lower than that treated with chloramphenicol, erythromycin or penicillin, but not lower than that treated with tetracycline. Mice that have responded to the phage treatment revealed the lower numbers of V. parahaemolyticus in small intestine and less damage on small intestine compared to the untreated mice. Therefore, we suggest that the phage treatment appears effective to the infection by V. parahaemolyticus.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

A 45-Year-old para 1-0-1-1 had submucosal myoma diagnosed by ultrasonogram and hysteroscopic examination. During 60 minutes hysteroscopic myomectomy, 8,000 ml of sorbitol-mannitol distention medium was used and 6,500 ml collected, resulting in a deficit of 1,500 ml. The patient received Ringer`s lactate 1,000 ml intravenously. Her urine output was 400 ml. Blood loss was 40 ml. After operation, hyponatremia(115 mEq/L) was developed and pulmonary edema was also diagnosed clinically at that time and later confirmed by chest radiograph. The judicious administration of diuretics and normal saline fluid replacement to prevent overcorrection to hypernatremia resulted in return of serum electrolytes to normal level and resolution of the pulmonary edema by postoperative day 1. We have experienced a case of pulmonary edema during hysteroscopic myomectomy with sorbitol-mannitol distention medium, which is presented with a brief review of literatures.

CT scans of 23 patients with gallbladder carcinoma were retropectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes around the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35%. The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

The halophilic bacterium, Vibrio vulnificus, causes acute fulminating wound infections and septicemia in human. Especially the septicemia shows high mortality above 50%. In Korea, septicemia by V. vulnificus was reported at westem and southern coast in every year. Here, we try to isolate this V. vulnipcus at Kyoung-nam area and coast of Pusan during 1996. Purposed sites were Dadaepo, Songjung, Chungsapo and Mipo of Pusan and Kijang, Ilkuang, Juksoung, Dongam, Waljun and Chilam of southern sea. Total 40 strains of V. vulnipcus were isolated from sea samples. Biochemical characteristics of isolated V. vulnificus were almost same with reference strain V. vulnificus ATCC 27562 on Farmer's tests and on API 20E kit test. V. vulnificus isolates in 1996, fermented cellobiose and salicin but arabinose. and had resistance to 7% sodium chloride.

Subtrochanteric fractures of the femur are difficult to manage successfully. Two factors, involvement of cortical bone tissue and concentration of stress, frequently have been mentioned as reasons for the high incidence of failure in the treatment of these fractures. We studied 37 patients with 38 subtrochanteric fractures treated at the Seoul Red Cross Hospital from Feb. 1978 to Nov. 1983. The results were obtained as follows: 1. Of the 37 patients studied, 29 were male and 8 female. The majority of male patients (representing 62.1%) were between 21 and 50 years of age, while 7 of 8 female patients were after 50years of age. 2. In 27 (73.0%) of our patients, the fracture resulted from high-energy trauma, traffic accident or fall from height. 3. Many fractures in the present series could not be classified in the manners described by Fielding, Zickel or Seinsheimer. So, we could not find any correlation between fracture type and used fixation device or its prognosis. 4. The associated injuries, which were relatively common in lower limb (10 cases) and pelvis (8 cases), made the fractures more difficult to treat. 5. Of the 38 fractures, 35 (92.1%) were treated by operative means. The Jewett nail was the device most commonly used, with a total of 11(31.4%) fractures being so treated. 6. The average time from operation to partial weight bearing was 12.9 weeks. 7. The average time untill clinical union was about 14 weeks and radiographic union about 24 weeks. 8. From these series, it was considered that, although early weight bearing is frequently impossihle, Jewett nail, plate and screw, compression hip screw, Judet plate or blade plate can be applied successfully to the treatment of subtrochanteric fractures of the femur if the most proper one which can stabilize the lesion effectively is selected and weight bearing is delayed for a sufficient period.
