1.Immunohistochemical Study of the Vascular Endothelial Growth Factor in Gastric Carcinoma.
Korean Journal of Pathology 1997;31(5):401-409
Many studies have shown that angiogenesis plays an important role in the growth, the progression, and the metastasis of a solid tumor. The vascular endothelial growth factor(VEGF) is thought to be a selective mitogen for endothelial cells. Twenty eight advanced gastric carcinomas and twenty early gastric carcinomas were investigated by staining with polyclonal antibody against the VEGF. Correlation between the expression of the VEGF and the clinicopathologic features of gastric carcinoma were studied. The VEGF was mainly localized to the cytoplasm of carcinoma cells. Normal gastric foveolar epithelium was not immunoreactive, but some endothelial cells were weakly immunoreactive with an anti-VEGF antibody. Expression of the VEGF was significantly higher in advanced gastric carcinoma than in early gastric carcinoma (p=0.003). Expression of the VEGF was correlated with the depth of tumor, the lymph node metastasis, and the stage (p<0.05). The VEGF positivity was significantly higher in moderately and poorly differentiated gastric carcinoma than in well differentiated gastric carcinoma. The VEGF scores of the metastatic foci in the lymph nodes were higher than that of the primary tumors, which were followed by deep and superficial portions of the primary tumors in a descending order (p<0.05). In summary, the expression of the VEGF may be associated with progression and metastasis of a gastric carcinoma and may also be a good prognostic factor in a gastric carcinoma.

2.Prevalence of Lymphoid Follicles in Helicobacter Pylori Associated Peptic Ulcer and Non-ulcer Dyspepsia in Human Stomach.
Korean Journal of Pathology 1996;30(12):1083-1090
To determine the prevalence of lymphoid follicles in Helicobacter pylori(H. pylori) positive and negative gastritis and its relationship to age, biopsy site, gastritis activity, degree of gastritis, number of H. pylori and gastritis score in H. pylori associated gastritis, we examined the gastric tissue of patients with 121 nonulcer dyspepsia and 99 peptic ulcers. The gastritis score was obtained by adding together the figures for gastritis degree, gastritis activity and number of H. pylori. H. pylori was detected in 75.2% of nonulcer dyspepsia, 84.5% of gastric ulcers and 90.3% of duodenal ulcers. Lymphoid follicles were found in 63.3% of H. pylori associated gastritis and 4.7% of H. pylori negative gastritis, and there was a strong relationship between the prevalence of lymphoid follicles and H. pylori infection(P<0.01). Lymphoid follicles were found in 100% of H. pylori associated gastritis, showing severe chronic inflammatory cell infiltration, and strong relationship between the prevalene of lymphoid follicles and the degree of gastritis (P<0.01). There was no significant difference among lymphoid follicles, age, biopsy site, clinical diagnosis, gastritis activity and number of H. pylori. Lymphoid follicles were found in 58.3% of gastritis score 4, 67.6% of gastritis score 7 and 100% of gastritis score 9, and there was significant correlation between the prevalence of lymphoid follicles and a gastritis score(P<0.01, R=0.85). In summary, gastric lymphoid follicle is significantly associated with H. pylori infection and its presence in H. pylori associated gastritis is related to chronic inflammatory cell infiltration.

Angiogenesis is a crucial step in tumor growth and progression. Scarce data is available on angiogensis in gastrointestinal tumors. We studied 16 normal colon, 44 adenomas and 29 carcinomas to evaluate angiogenesis in colorectal tumors and to assess the correlation among p53 protein, proliferative activity and other clinical prognostic parameters. Endothelial cells were immunostained with an anti-Factor VIII mAb; in each case three microscopic fields(x 200) were counted: average number of the three fields was defined as microvessel density (MVD). p53 protein expression was 45.5%(20/44) in adenomas, and 79.3%(23/29) in carcinomas (p<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploid tumors, 100%(8/8) in aneuploid tumors (p=0.07), 100%(8/8) in well differentiated tumors, and 50%(2/4) in poorly differentiated tumors (p=0.09). MIB-1 score was 2.3+/-0.7(38) in adenomas, 3.4+/-0.5(29) in carcinomas (p<0.01). There was no significant correlation between p53 protein and MIB-1 score. MVD was 10.4+/-4.1(16) in the normal mucosa, 21.5+/-7.9(39) in the adenomas, 35.3+/-9.7(26) in carcinomas (normal versus adenomas, p<0.01; adenomas versus carcinomas, p<0.01). MVD was 25.8+/-5.4(2) in carcinomas confined to mucosa, and 36.1+/-9.6(24) in carcinomas with transmural invasion. The higher MIB-1 score was in carcinomas the more MVD increased but there was no statistical significance (r=0.38, p=0.055). MVD of carcinomas was not associated with nodal metastasis, p53 expression, and DNA ploidy. p53 protein and MIB-1 expression are useful methods for the evaluation of malignancy, and tumor angiogenesis is an early event in a colorectal tumor but MVD does not correlate with prognostic parameters except for the tumor depth.

Heat shock protein 70 (HSP70) is a chaperone that binds to mutant p53 and consequently can regulate its accumulation or localization. Its expression is upregulated in tumor cells. We studied 44 adenomas and 29 carcinomas of colorectum to evaluate the expression of HSP70, and to assess the correlation among p53 protein and other clinical prognostic parameters. HSP70 expression was scored according to staining intensity and extent. p53 protein expression was 45.5%(20/44) in adenomas and 79.3%(23/29) in carcinomas(P<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploidy tumors, 100.0%(8/8) in aneuploidy tumors(P=0.07), 100.0%(8/8) in well-differentiated tumors, and 50.0%(2/4) in poorly differentiated tumors(P= 0.09). HSP70 expression mainly revealed a fine granular cytoplasmic staining pattern in tumor cells. HSP70 was focally detected in some lymphocyte, ganglion cell and normal mucosa. HSP70 expression was 46.3%(19/41) in adenomas and 93.1%(27/29) in carcinomas. HSP70 score was 0.9+/-1.3 in adenomas(n=41) and 5.5+/-3.5 in carcinomas(n=29)(P<0.0005). Its score was 1.7+/-1.6 in p53 positive adenomas and 0.3+/-0.6 in p53 negative adenomas(P<0.005), and its expression rate was higher in p53 positive carcinomas than p53 negative carcinomas (P>0.05). There was no significant correlation among HSP70, tumor size, Dukes'stage, nodal metastasis, depth of tumor invasion, DNA ploidy and tumor differentiation. In conclusion, HSP70 and p53 protein appear to be correlated to each other, and that HSP70 and p53 protein may play a certain role in the progression of colorectal tumor. Further studies are needed for determining their prognostic factors in colorectal carcinoma.

PURPOSE: The reported clinical manifestations in Turner syndrome were different by karyotypes, countries and races. So, We evaluated the physical findings & medical problems in patient with Turner syndrome according to karyotype. METHODS: We examined prospectively 53 cases that diagnosed as Turner syndrome by chromosome study at the Pediatric Endocrine Clinic, YUMC from May 1999 to Aug 1999. According to the karyotype, they were divided into 3 groups:45, X(22 cases, 41.5%), mosaicism(18 cases, 34%) and structural aberration group(13 cases, 24.5%), and 53 cases were reevaluated by prepared protocol of 22 abnormal physical findings and 4 medical problems. Chi-square test was used for statistic analysis. RESULTS: 1)In case of 45, X group, they had short stature(100%), cubitus valgus(95.5%), widely spaced nipples(86.4%), shield chest(72.7%), low posterior hair line(68.2%), in case of mosaicism group, they had short stature(100%), cubitus valgus(72.2%), high arched palate(66.7%), widely spaced nipples(61.1%), short neck(61.1%) and in case of structural aberration group, they had short stature(100%), high arched palate (92.3%), widely spaced nipples(92.3%), low posterior hair line(76.9%), shield chest (76.9%), in frequency order. Short stature was the most common finding in Turner syndrome. The incidence of high arched palate was significantly higher in structural aberration group(P<0.05). 2)In case of 45, X group, they had otitis media(63.6%), thyroid problem(4.5%) and no renal problem and cardiac problem, in case of mosaicism group, they had otitis media(38.9%), thyroid problem(5.6%) and no renal problem and cardiac porblem and in case of structural aberration group, they had otitis media(61.5%), thyroid problem(15.4%), renal problem(7.7%) and cardiac problem(7.7%) in frequency order, they had no statistical difference in among three groups. CONCLUSION: In case of 45, X group, the incidence of cubitus valgus, webbed neck were more common findings and of high arched palate, micrognathia were less common findings compared to other group. In case of mosaicism group, the incidence of micrognathia, epicanthal fold were more common findings and wide spaced nipples, antimongoloid fissure were less common findings compared to other group. In case of structural aberration group, the incidence of high arched palate is most common finding among 3 group(P<0.05) and pigmented nevi and epicanthal fold were less common findings compared to other group. The incidence of medical problems such as otitis media and thyroid problem were than other foreign country reports.

A study of the volume and linear measurements of the breast to determine new nipple positions for 142 subjects was undertaken. Volume determination was done by using the Grossman-Roudner device. The size and shape of the female breast may differ significantly, and such size and linear measurements have to be measured accurately prior to breast aesthetic surgery. Statistical analysis of these results are closely related to physical constitution(height, weight, chest circumference). There have been increasing changes in linear measurement and decreasing changes in breast volume during the last 10 years, The results were as follows: 1) the mean distance from the midclavicular point to the nipple was 19.5cm, the distance from the sternal notch to the nipple was 19.4cm, the distance between nipples was 18.6cm, and the areolar diameter was 3.3cm, 2) the regression equation for the midclavicular point to the nipple was 7.236+ 0.00077x height(cm)+ 0.233 x weight(kg), for the sternal notch to the nipple was 8.845-0.0039 x height(cm)+ 0.214x weight(kg), for the distance between nipples was 11.192 - 0.0033xheight(cm)+ 0.151x weight(kg), and for the areolar diameter was 4.031+0.02xheight(cm)-0.048 x weight(kg),3) the mean value of breast volume of the left side was 209.6cc, and that of the right side was 211.8cc, 4) the regression equation for the mean breast volume was -137.673 + 6.668 x weight(kg), which was equal to -528.414 + 9.115x chest circumference under the axilla(cm) and -468.420 + 8.298 x chest circumference across the nipple (cm). In conclusion, these data could be useful for numerous aspects of breast surgery, including augmentation mammoplasty, mastopexy, reduction mammoplasty, and correction of asymmetrical breasts as the standard for Korean females, if we know the body constituents (weight, chest circumference) before surgery.

BACKGROUND: Few studies have reported the results of arthroscopic coracoplasty concomitantly conducted with subscapularis tear. Therefore, this study was conducted to examine and compare the outcomes of arthroscopic subscapularis repair after arthroscopic coracoplasty using either the subacromial approach or rotator interval approach. METHODS: We retrospectively reviewed 51 patients who underwent coracoplasty with subscapularis repair. The patients were grouped according to whether the subacromial approach group (24 patients) or rotator interval approach group (27 patients) was used during coracoplasty. Preoperative and postoperative visual analogue scale scores, American shoulder and elbow surgeons scores, Korean shoulder scores, and range of motion (ROM) were assessed. Assessment of repaired rotator cuff tendon integrity was performed at 1 year after surgery using either magnetic resonance imaging or ultrasonography. RESULTS: At final follow-up, overall functional scores and ROM improved significantly in both groups when compared with preoperative values (p>0.05). The re-tear rates were not significantly different between groups; however, the rotator interval approach group showed a significant increase in ROM compared with that in the subacromial approach group (p<0.05). CONCLUSIONS: Arthroscopic coracoplasty conducted concomitantly with subscapularis repair can provide a satisfactory outcome. There were no significant differences between the two approach groups regarding final functional scores and re-tear rates. However, the rotator interval approach group showed a greater increase in ROM at final follow-up, especially in external rotation.

Jang Han KIM ; Jung Bin LEE ; Yoon Seong LEE
Korean Journal of Legal Medicine 1999;23(1):35-42
This treatise summarizes the medical facts about the persistent vegetative state(PVS) and the associated issues. In August 1998, the opinions of the 380 neurologists and the 1007 neurosurgeons are inquired about the diagnostic criteria of PVS, the degree and the withdrawal of treatment on PVS patients. The response rate is 18.8%. The diagnostic criteria of PVS is determined by the items approved above 5007o of responses. (1) no evidence of cerebral function and an inability to interact with visual, auditory stimuli and follow commands. (2) maintaining the respiratory function with spontaneous respiration and normal respiratory pattern. (3) spontaneous eye opening and eye ball movements without sustained tracking. (4) variably preserved brain stem reflexes. (5) presence of sleep-wake cycles. (6) (1)-(5) symptoms should be persist for 6 months after the development of vegetative state. (7) the diagnostic criteria of PVS should be applied more than 3 times during the minimum observation period. (8) this diagnostic criteria of PVS could be applied to adults over 7 ages. As to the degree of treatment, nasogastric tube feeding and air-way keeping through the tracheostomy are approved over 9007b. Also antibiotics can be used in infection. As to the withdrawal of treatment, do not resuscitate order of patient s family is accepted by 46.1% in an emergency condition like cardiac arrest. But discharge against medical advice by the patient s family is accepted by 73.107o in non-emergency condition. In the case of neonates, parents decision is more determinative than any other thing.
