Purpose: Bezoars are the uncommon result of ingestion of poorly digestible or indigestible substances. It is defined as retained concretions of animal or vegetable material in the gastrointestinal tract. The aim of this study was to review and analyze in these cases with reviewing literature. Methods: The medical records of 12 cases, treated between May 1999 and April 2009, were reviewed. The clinical characteristics, as well as the diagnostic evaluations and results of medical and surgical treatment, were also analyzed retrospectively. Results: Of the 12 cases, 6 men and 6 women, the bezoars were in the stomach, jejunum and ileum or in both stomach and jejunum in 1, 2, 7 and 2 cases, respectively. 4 patients (33.3%) had a history of gastric or duodenal ulcer following previously received gastric surgery such as subtotal gastrectomy or truncal vagotomy with pyloroplasty. In 3 cases, the bezoars were found in operative field under the impression of intestinal obstruction due to adhesive ileus, which could not be found by preoperative radiologic evaluation. Among the 12 cases, 11 cases were successfully treated by operative and endoscopic removal, but 1 case expired due to sepsis. Conclusion: A bezoar occurs mainly in patients who have previously undergone a gastric operation. Surgeons should keep in mind the possibility of bezoars in patients presenting an intestinal obstruction following a past gastric operation. The principle of treatment for bezoars used to be surgery, but recently gastric bezoars are often treated by gastrofiberscopy.

In three phase fluidized beds with binary particle mixtures of glass beads, gas-liquid mass transfer characteristics have been studied in a 6.3cm I.D. and 160cm height acryl column. The three phase fluidized beds were consisted of tap water, carbon dioxide mixed with oil-free compressed air and binary mixtures of glass beads, respectively. Then binary mixtures used were five combination of three types of glass beads. Particular attention is paid to the mass transfer characteristics in bubble flow regime. Till now, the study of binary particle mixtures system in three phase fluidized beds have been reported very a few in hydrodynamics, but the study of mass transfer have been not reported. Thus, in this investigation the effects of gas velocity(2.0-10.0cm/sec), liquid velocity(1.26-15.74cm/sec) and particle size(1.3, 3.0, 6.0mm) and weight percent of binary particle mixtures on volumetric mass transfer coefficients along with the various bed height have been determined. Volumetric mass transfer coefficients, K₁a was calculated by using the computer optimization with plus flow model. In result 1. Bed porosity increased with gas and liquid velocity in beds of 3.0mm and 6.0mm single particles respectively. However, bed porosity decreased with lower gas velocity in a bed of 1.3mm single particles so that bed contraction is observed. A bed of 3.0mm single particles showed intermediate phenomena between bed expension and bed contraction. 2. The three phase fluidized beds by binary particle mixtures have been higher minimum fluidized velocity than that by single particles. Then, bed contraction was shown in beds of mixed particle with 1.3mm and 3.0mm. However, when weight fraction of large particles reached to 0.75, a bed of mixed particles was shown similar to a bed of large particles. 3. In three phase fluidized beds by binary particle mixtures bed porosity and liquid holdup were correlated in terms of Froude number of liquid and gas, and Reynolds number of liquid and gas, and Reynolds number of liquid by using harmonic mean diameter. Bed porosity εl +εg = 0.4324Fr₁ 0.0497Fr?? 0.0012Rel 0.0537 Liquid hold-up ε₁=0.1541Fr₁ 0.1917Fr?? -0.0887Re₁ 0.1596 4. In three phase fluidized bed of single particles, liquid phase concentration increased with increasing gas velocity and decreasing liquid velocity. However, in a bed of 3.0mm single particles with intermediate phenomena, liquid phase concentration increased rapidly with gas velocity in grid zone, then decreased slowly and increased again. Therefore, concentration profile of third order curve was shown. 5. In three phase fluidized beds of binary particle mixture, this tendency was similar to a bed of single particles. However, liquid phase of large and small particles had likely transitional values according to weight fraction of mixed particles. 6. Volumetric mass transfer coefficients calculated by plug flow model increased with increasing gas and liquid velocity as well as particle size and weight fraction of large particles. 7. Volumetric mass transfer coefficients, K??a, were correlated in terms of gas and liquid velocity, poarticle size and weight fraction of mixed particles.

It is extremely difficult to treat to the comminuted open fractures of supracondyle of femur. Internal fixation with plates and screw or intramedullary nailing of open fracture is high risk of infection and circulatory compromising at the fracture site. External fixation reduces the risk of infection and permits easy access for wound care, early mobilization of joints and weight bearing. We reviewed nine cases of open supracondylar fractures of femur treated with Ilizarov method from February l993 to December 1995 and obtained the following results. 1. The average time of bony union was 2 weeks. According to AO classification, the average time of bony union was 22.7 weeks in type A and 29.3 weeks in type C. According to classification of Gustilo and Anderson, the average time of bony union was 21 weeks in type II, 27.3 weeks in type IIIa and 30 weeks in type IIIb. 2. The Neer's criteria was based on the final functional and anatomical rating for supracondylar fracture of femur. According to this criteria, excellent was 1 case, satisfactory in 7 cases and unsatisfactop in 1 case. 3. The complications were divided into problem. obstacle and complication;problem in 9 cases, obstacle in 5 cases and complication in 3 cases. We conculded the Ilizarov technique is a useful method in management of the severe comminuted fractures and extensive soft tissue injury of the supracondylar fractures of femur.
