Purpose: The macroscopic diagnosis of tumor invasion through the serosa during surgery is not always distinct in patients with gastric cancer. The prognostic impact of the difference between macroscopic findings and pathological diagnosis of serosal invasion is not fully elucidated and needs to be re-evaluated. Materials and Methods: A total of 370 patients with locally advanced pT2 to pT4a gastric cancer who underwent curative surgery were enrolled in this study. Among them, 155 patients with pT3 were divided into three groups according to the intraoperative macroscopic diagnosis of serosal invasion, as follows: serosa exposure (SE)(-) (no invasion, 72 patients), SE(${\pm}$) (ambiguous, 47 patients), and SE(+) (definite invasion, 36 patients), and the clinicopathological features, surgical outcomes, and disease-free survival (DFS) were analyzed. Results: A comparison of the 5-year DFS between pT3_SE(-) and pT2 groups and between pT3_SE(+) and pT4a groups revealed that the differences were not statistically significant. In addition, in a subgroup analysis of pT3 patients, the 5-year DFS was 75.1% in SE(-), 68.5% in SE(${\pm}$), and 39.4% in SE(+) patients (P<0.05). In a multivariate analysis to evaluate risk factors for tumor recurrence, macroscopic diagnosis (hazard ratio [HR], SE(-) : SE(${\pm}$) : SE(+)=1 : 1.01 : 2.45, P=0.019) and lymph node metastasis (HR, N0 : N1 : N2 : N3=1 : 1.45 : 2.20 : 9.82, P<0.001) were independent risk factors for recurrence. Conclusions: Gross inspection of serosal invasion by the surgeon had a strong impact on tumor recurrence in gastric cancer patients. Consequently, the gross appearance of serosal invasion should be considered as a factor for predicting patients' prognosis.

From September 1993 to August 1997, we treated ovarian disorders in 1,782 repeat breeder cows after diagnosis by ultrasound on 35 farms in Kyeong-ki do. The rates of ovarian appearance were 59.8% of CL group, 16.7% of ovarian atrophy or hypofunction, 15.4% of luteal cyst, 4.3% of follicular cyst and 3.7% of follicle group in diagnosis with rectal palpation and ultrasound. The results of treatment for ovarian disorders were 1,316 cows(73.8%) in estrus, 348 cows(19.5%) in non-detected and 118 cows(6.6%) in unidentified. The rates of PGF$_2$$\alpha$, GnRH and mineral vitamin complex treatment to estrus were 79.6, 69.2 and 50.3%. Two groups were treated with 5 ml PGF$_2$$\alpha$ intramuscular injection(I.M.) and 1.5 ml PGF$_2$$\alpha$ intraovarian injection(I.O.), and the results of 1.5ml PGF$_2$$\alpha$ I.0. were significantly higher than that of 5ml PGF$_2$$\alpha$ I.M. in inductiom estrus(p<0.05). The pregnant rates were 29.8% in total repeat breeder cows with ovarian disorders following diagnosis and treatment. In summary, rectal palpation and ultrasonography were proven to be useful tools of diagnosis and treatment in ovarian disorders, and it was also suggested that the response to treatment with PGF$_2$$\alpha$ I.0. was better than PGF$_2$$\alpha$ I.M.

Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease caused by autoantibodies to proteins in the oral mucosa and skin. It is a rare disease with an annual incidence of 2.059 per million in South Korea. In many patients with PV, oral mucosal lesions precede other lesions elsewhere, and oral lesions can be the only manifestation. Early diagnosis is important because the disease has a high mortality rate if untreated appropriately in the early stages, and rapid treatment initiation is associated with rapid disease control. Oral PV lesions are clinically variable. In this study, we describe oral PV lesions in a 60-year-old woman, a 75-year-old man, and a 60-year-old man presenting with various clinical presentations. Oral PV lesions can affect any part of the oral mucosa, including the buccal mucosa, gingiva, tongue, palate, and free mucosa, and can vary in appearance from desquamative gingivitis, painful ulcers, and erosions to aphthous-like stomatitis. Clinicians should be aware of the difficulty of early diagnosis in PV, particularly when oral lesions are the only manifestation, and should consider many factors, including the patient's age, to make an accurate diagnosis and manage oral lesions to improve the patient's quality of life and avoid delayed diagnosis.

The purpose of this study is to determine the changes of ultrasonographic appearance of stomach, pylorus and duodenum in relation to food intake and administration of contrast medium in dogs. Ultrasonograms were obtained with 5.0MHz sector transducer. After placing the dogs in dorsal recumbency, scanning was performed at the 8th intercostal space. The mean inner diameter of stomach immediately after food intake, 2, 4 and 6 hours was 47.9, 51.5, 46.8 and 40.6mm, respectively. The diameter of pylorus immediately after food intake, 2, 4 and 6 hours was 7.4, 9.7, 8.9 and 6.0mm, respectively(p<0.01). The diameter of duodenum immediately after food intake 2, 4 and 6 hours was 12.5, 7.9, 11.9 and 11.8mm, respectively(p<0.01). Before administration of contrast medium, the mean inner diameter of stomach, pylorus and duodenum was 38.6, 7.2 and 9.5mm, respectively. After administration of contrast medium, the diameters of stomach, pylorus and duodenum was 42.8, 7.7 and 9.9mm, respectively. It may be concluded that the ultrasonographic values determined in this study can be used as references for the diagnosis of gastrointestinal disease in dogs.

Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.

Florid osseous dysplasia (FOD) is an uncommon, benign, cemento-osseous lesion of the jaws. The etiology of FOD is still unknown. It is often asymptomatic and may be identified on routine dental radiographs. The classic radiographic appearance of FOD is amorphous, lobulated, mixed radiolucent/radiopaque masses of cotton-wool appearance with a sclerotic border in the jaws. In our case the lesion was found incidentally on routine periapical radiographs taken for restored teeth and edentulous areas. For further and detailed examination, a panoramic radiograph and cone-beam computed tomograph (CBCT) were taken. The panoramic radiograph and CBCT revealed maxillary bilateral and symmetrical, non-expansile, well-defined, round, radiopaque masses in contact with the root of the maxillary right second molar and left first molar teeth. Our aim in presenting this case report was to highlight the importance of imaging in diagnosis of FOD.

Serial ultrasonographic examinations were daily performed on 11 bitches (5 Maltese and 3 Yorkshire terrier) from day 15 until parturition to determine the time of Sift detection and ultrasonographic appearance of the fetal and extra-fetal structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when p18sma progesterone concentration was first increased above 4.0 ng/ml. The gestational length in 8 bitches was 61.5 (range: 60-64) days. The initial detection time of fetal and extra-fetal structures were: gestational sac at days 20.5 (18-23); zonary placenta in the uterine wall at days 25.4 (24-30); yolk sac membrane at days 25,5 (23-37); amniotic mombrane at days 28.7 (25-32); embryo initial detection at days 23.3 (20-26); fetal heartbeat at days 23.9 (21-27); fetal movement at days 31.3 (26-34); limb buds at days 32.1 (29-35); rotomarh at days 35.3 (32-40); urinary bladder at days 35.6 (33-39); skeleton at days 37.8 (37- 40) and kidney at days 45.3 (41-49), respectively.

Purpose In Sasang Constitution Medicine, persons are divided into four types such as Taeyangin, Taeumin, Soyangin and Soeumin according to their appearance, moral nature and characteristic of constitutional symptoms. In teenager group, diagnosis of constitution based on their appearance was so difficult that we adopted new diagnostic method which measures and compares body compositions. Methods 180 middle school students who live in Pusan were studied from 20th of March, 1999 to 20th of March, 2000. After practicing Questionnaire(I), QSCC(Questionnaire of Sasang Constitution) I , QSCCII, we have measured the height and body compositions with Inbody 3.0, five times. Results 1. The results of Sasang Constitution analysis showed 91 students were classified as Taeumin(50.3%), 75 as Soyangin(41.4%), 14 as Soeumin(7.7%), and 1 as Taeyangin(0.6%). 2. The level of total body water, muscle area, BMR(Basal Metabolic Rate), BCM(Body Cell Mass), and AMC(Arm Muscle Circumference) were increased during spring and summer. That of body weight, fat body weight, fat body weight ratio, waist hip ratio, and BMI(Body Mass Index were increased during fall and winter. 3. In Taeumin and Soyangin groups, the changed capacity of total body water, muscle area and BMR were increased with statistical significance. 4. Waist hip ratio of Soeumin group was reduced more than those of Taeumin, Soyangin groups with statistical significance.

Purpose: Facial trauma is increasing along with increasing popularity in sports, and increasing exposure to crimes or traffic accidents. Compared to the 3D CT of 1990s, the latest CT has made significant improvement thus resulting in higher accuracy of diagnosis. The objective of this study is to compare 64 channel 3 dimensional volume CT(3D VCT) with conventional 3D CT in the diagnosis and treatment of facial bone fractures. Methods: 45 patients with facial trauma were examined by 3D VCT from Jan. 2006 to Feb. 2007. 64 channel 3D VCT which consists of 64 detectors produce axial images of 0.625 mm slice and it scans 175 mm per second. These images are transformed into 3 dimensional image using software Rapidia 2.8. The axial image is reconstructed into 3 dimensional image by volume rendering method. The image is also reconstructed into coronal or sagittal image by multiplanar reformatting method. Results: Contrasting to the previous 3D CT which formulates 3D images by taking axial images of 1-2 mm, 64 channel 3D VCT takes 0.625 mm thin axial images to obtain full images without definite step ladder appearance. 64 channel 3D VCT is effective in diagnosis of thin linear bone fracture, depth and degree of fracture deviation. Conclusion: In its expense and speed, 3D VCT is superior to conventional 3D CT. Owing to its ability to reconstruct full images regardless of the direction using 2 times higher resolution power and 4 times higher speed of the previous 3D CT, 3D VCT allows for accurate evaluation of the exact site and deviation of fine fractures.
