1.An Immunohistochemical Study for the ras and neu Oncoprotein and Epidermal Growth Factor Receptor in the Uterine Cervical Carcinoma.
Korean Journal of Gynecologic Oncology and Colposcopy 1993;4(1):43-55
To evaluate the expression of ras, neu oncoprotein a.nd epidermal growth factor receptor (EGFR) on uterine cervieal carcinoma, imimunohistochemieal staining was performed on 9 cases of dysplasia, 39 cases of careinoma in situ(CIS), 32 cases of microinvasive earcinoma(WIC) and 60 cases of frankly invasive carrinoma(FIC). The results obtained were as follows: Ras p21 protein was positive in 29.5% of total cases, and it was very low in dysplasia lesion(12. 5%) and CLS(17.9%) while it was high in MIC(31.3%) and FIC(38.9%). In CIS, parabasal cell type showed positive reaction in only 8.7%, but pleomorpkic type showed 60.0% positivity. Invasive carcinoma showed no significant differences between histolegic types. Expression of neu protein was very high in caneerous group(around 95%) and slight,ly lower in dysp]asia(75.0%). No differences were found depending on histologic types and stages. EGFR was expressed in 51.8% of total cases; 12.5% of dysplasia; 54.2% of all cases of carcinoma. Keratinizing type of CIS showed highest positive reaction(90,0%), of which tendency were also noted in keratinizing type of i.nvasvie cinoma(76.2%). The results suggested that ras and EGFR could be used as a factor of prognostic value.

There are many established roentgen signs of ascites such as hepatic angle sign, generalized graying of the abdomen, frog belly appearance and Hellmer's sign. These signs are easily recognized in the standard flat abdomen film. It is however hardly possible to recognize such signs in small films of double contrasted upper GI series. By a retrospectroscopical observation we were able to find some interesting signs of massive ascites in small size films of double contrasted stomach and duodenum of upper GI series. The clinical materials consisted of 27patients with massive ascites and 30 normal subjects. The signs we observed were ;(1) Constriction deformity of the junction of the fundus and body of the stomach. We named this "waist" sign. This constriction was attended by convergence of mucosal folds. We called this "converging folds" sign. (2) The fundus assumed electric bulbappearance with its long axis directed vertically. We called this "electric bulb" sign. In normal subjects the fundus assumed beret-cap like appearance. These signs were only appreciated in the supine and RAO views and not in other views. Of these new signs of massive ascites where fundic view was obtained in supine or RAO position.

3.Clinical Experience of the Lower Ureteral Stones.
Korean Journal of Urology 1996;37(6):683-688
Several therapeutic methods, expectant management, endourology and ESWL can be used in the treatment of ureteral calculi. In a retrospective analysis during a 3-year period, 96 patients showed spontaneous passage of stones. 164 patients treated with endourologic procedures and 168 who underwent ESWL with a Wolf Piezolith 2300 were analysed as to the success rate in stone removal, complication rate, anesthesia and hospitalization. The mean stone size was 5mm in the expectant management group and 6mm in both endourology and ESWL groups. 11mm was the mean size in the surgical group. Complete removal of all stone fragments was achieved in 52.5% of the expectant managed patients. The overall success rate were comparable with modalities which were 94.5% in endourology and 91.4% in ESWL and 100% in ureterolithotomy. The group treated endourologically had a better success rate but no significant difference to ESWL group. On the other hand, the group treated with ESWL had a shorter hospitalization, lower complication rate, no need for anesthesia. These observations showed that in situ ESWL provides a optimal first line therapy for distal ureteral calculi larger than 5mm, while ureteroscopy is better reserved as a salvage procedure should ESWL fail. Expectant management is more efficient for distal ureteral calculi less than 5mm.

Oral cholecystography is one of the most relible and widely used x-ray examination which enables us to observe not only morphological features of the gallbladder (GB) but also its functioning state. It was disclosed that functional evaluation of the GB is mandatory to recognize such kinetic disorders of the viscus as acalculous cholecystitis or dyskinesia. For the purpose of functional evaluation, fat meal has been used traditionally. Recently, cholecystokinin(CCK) and ceruletide were introduced into clinical diagnosis of the GB, the usefulness of which we have confirmed. In the present study we have made an attempt at improving cholecystagogic effect of conventional fat meals(FM) such as whole mild and egg yolk by changing the posture of the examined from sitting up to right decubitus position after the ingestion of fat meal. The hypothesis involved in this study is that the presence of quantitatively more fat meal in the duodenum per unit time may result in more effective cholecystagogic action and such a setting would be created by enhancement of pyloric passage of fat meal by decubitus posturing. Clinical materials consisted of 280 normal oral GB series (136 males and 144 females) andthey were divided into 4 equally numbered groups of mild sitting and mild decubitus and egg sitting and eggdecubitus. Upon confirming satisfactory opacification of the GB 11 hours after the ingestion of 3g of sodiumipodate or iopanoci acid either 2 pieces of medium sized hen's egg yolk were given. The xaminess were then allowed either sitting up comfortably on a bench or lying down on the right flank on a couch. After the ingestion of fat mean, x ray was taken at the end of 30 minutes in all but the mild decubitus group in which x rays were taken serially at the end of 5, 15, 30 and 60 minutes. The frontal area of each opacified GB was measured by using aplanimeter and the contraction rate before and after fat meal stimulation was calculated by the following equation and delineation of the biliary tree was analyzed in each group. Contraction rate (%) = (1

Visualization of falx cerebri on non-enhanced CT of children with severe head injuries (the falx sign) has been regarded as an evidence of subarachnoid hemorrhage. On the contrary, other authors have reported reverse results. To evaluate clinical significance of the falx sign, authors studied frequency of visualization and CT number of falx cerebri and dural sinuses in 65 children with head injury and 65 children without head injury examined by cranial CT at the Dep. of Radiology, St. Paul's Hospital, Catholic Medical College from March to Sept. 1981. All patients with head trauma were studied within 1 week of the traumatic event. Visualization of falx cerebri was observed at slice in the region of lateral ventricle and slice near to vertex respectively. On the slice in the region of lateral ventricle, falx cerebri was identified in 82% of all of the children examined, of which 92%showed partial visualization of falx cerebri and remaining 8% totally. On the slice near to vertex, falx cerebri was identified in 92% of all the children examined, of which 38% showed partial visualization of falx cerebri and remaining 62% totally. In head trauma group, frequency of visualization of falx cerebri was 78% on the slice in the region of lateral ventricle and 89% on the slice near to vertex; in non-traumatic group, frequency of visualization of falx cerebri was 86% and 94% respectively. The highest numerical value of the falx densities averaged 47 Hounflieds (range, 32-63) in non-traumataic group, averaged 49 Housfields (range, 32-69) in head trauma group. All or a portion of the superior sagittal sinus was visualized in 59% of all of the cases studied, 50% in head trauma group, and 69% in nontraumatic group. The straight sinus was identified in 45% of all of the cases studied, 39% in head trauma group, and 51% in non-traumatic group. In conclusion, there was no distinction between head trauma and non-traumatic group in visualization of falx cerebri and dural sinuses, and we could frequently identify the falx density in normal. Also we could find that frequency for visualization of falx cerebri and drual sinuses increased as the age increased.

After a lobectomy the apearance of the chest roentgenogram may return so nearly to normal that it isfrequently very difficult to tell which lobe has been moved without refering to the thoracic surgeon's record. Thereriew of literature failed to disclose previous articles concerning the differential diagnosis between upper andlower lobectomy. Clues of a lobectomy may be found in the rib cage, hilar shadows, pleura and disphragms, but they do not specifically incidate which lobe has been removed. In the present study we anlaysed anatomico-spatialchanges of the pulmonary basal arteries, hilar point, vascular redistribution, diaphragm and rib cage on the plainchest films taken before and after a lobectomy in 33 cases seen at the Dept. of Radiology, St. Mary's Hospoital, Catholic Medical College. Firstly we observed the pulmonary basal artery after a lobectomy on plain chest film. In 12 cases of upper lobectomy the pulmonary basal artery was easily identified in every case. However in all of 21cases of lower lobectomy, the pulmonary basal artery was not identified. Next, a shift of the hilar point waschecked after a lobectomy. Regarding to vascular redistribution, the blood vessels was counted at upper and lowerlung fields by simon's method before and after a lobectomy, respectively. Finally, the level of the diaphragm wascompared in the pre. and post-opeative films and resected rib was scrutinized. The present study revealed that themost reliable sign to indicate specifically which lobe has been resected is persistence or disappearance of thepulmonary basal artery. Then i.e. in upper lobectomy the pulmonary basal artery was easily identified, but inlower lobectomy the pulmoanry basal artery was not dectable. Other findings such as vascular redistribution,elevated diaphragm and resected rib were not specific.

It is essential to estimate the liver size in the diagnosis of liver disease. Many approaches have beenattempted in the evaluation of liver size such as measurement of length, area and volume. Among these, area andvolume measurements are accurate but complicated. So various linear measurements including Pfahler's method havebeen commonly used. But to our knowledge, there was no report about linear diameter of liver in Korean adualts. Asingeneral, larger patients are likely to have larger liver than smaller ones, it seems to be more ideal toevaluate the liver size using relative ratio rather than absolute linear diameters. The main objectives of ourinvestigation were to determine the various diameters of normal and enlarged liver and the criteria ofhepatomegaly in Korean adults using absolute and relative ments. Our cases consisted of 95 clinically normalsubjects and 51 patients suffering from liver disease and diagnosed to have hepatomegaly on abdominal palpationand simple abdomen in the Dept. of Radiology, St, Mary Hospital during the period of 6 months since Jan. 1981. Wemeasured the liver size using 3 linear diameters. And as the reference measurement, the distance from the rightmargin of the liver to the left margin of spleen was also measured. We called this “abdominal transversediameter”(ATD). The results were as follows; 1. The diameters of liver were 13.4±1.6cm, 18.4±2.4cm, 19.2±2.6cmin normal group and 18.8±3.1cm, 23.5±3.0cm, 24.2±3.2cm in hepatomegaly group using midline verticaldiameter(MIVD), maximum vertical diameter (MAVD) and diagonal diameter(DD), respectively. The difference betweentwo groups were statistically very significant in every method(p<0.01). 2. The 99% tolerance limits of liverdiameters were 13.0-13.8cm, 17.8-19.0cm, 18.5-19.9cm in normal and DD, respectively. The midpoints between theupper limit of normal group and the lower limit spectively. These points are warranted to suggest criterias ofhepatomegaly. 3. There were statistical significant difference in the ratio of each diameter to ATD between normaland hepatomegaly group (p<0.01). We called this“hepato-abdominal ratio”. The “hepato-abdominal in hepatomegalygroup using MIVD, MAVD and DD, respectively. 4. The 99% tolerance limits of “hepato-abdominal ratio” were0.43-0.45, 0.59-0.63, 0.62-0.64 in normal group and 0.60-0.62, 0.75-0.77, 0.77-0.79 in hepatomegaly group usingMAVD, MAVD and DD, respectively. The midpoints between the upper limit of normal group and the lower limit ofhepatomegaly group were 0.52, 0.69, 0.70 using MIVD, MAVD and DD, respectively. These points are alsowarranted tosuggest criterias of hepatomegaly.

BACKGROUND: Smoking-related chronic obstructive pulmonary disease and chronic asthmatic bronchitis, which are the most important causes of chronic airflow obstruction (CAO), can occur together in a pat,ient and the prognoses of these two diseases are different each other. OBJECTIVE AND METHOD: To estimate the extent of asthmatic component in patients with CAO and to evaluate the role of atopy as a predictable index for reversibility of airflow obstruction, 89 CAO patients who were older than 40 years were examined retrospectively. RESULT: Only 15 patients (16.8%) showed an increase of >15% in FEV20 to inhaled salbutamol (short-term responder). However, 18 out of 32 patients (56.3%), who were not responded significantly to inhaled bronchodilator and performed a follow-up lung function study, showed an increase of ) 15% in FEV20 to anti-asthmatic therapy including corticosteroid for 3-4 weeks (long-term responder). Peripheral blood eosinophil count only was different between short-term responder and short-term nonresponder, and there was no difference in all of the measurements between short-term responder and long-term responder. However, there were significant differences in smoking, wheezing on auscultation, peripheral blood eosinophil counts, serum total IgE levels, and MAST atopy score between long-term responder and long-term nonresponder. The increase in FEV, following shortor long-term therapy was related to peripheral blood eosinophil counts and MAST atopy score, and it was significantly great,er in patients with high eosinophil counts or high atopy score. CONCLUSION: About 2/3 of patients with CAO who were older than 40 years had an asthmatic component ap atopy may be useful to predict good bronchodilator response to anti-asthmatic therapy.
