The effeciency of combined application of isotope scan and ultrasonography of thyroid was assessed in 91 patients with thyroid nodule. Malignancy rates were 35.5%, 18.8%, & 0% in solid, complex & cystic nodule group, respectively. No statistically significant co-relationship was found between isotope scan finding & ultrasonographic finding. Malignant nodules were found only in cold solid nodule group & cold complex nodule group, and rate of malignant nodule was different between them(45.8% in cold solid nodule group & 20.7% in cold complex nodule group). Difference between the rate of cystic change in benign & malignant nodule observed in our study(59.2% vs. 35.3%) was thought to explain at least partly the statistically different rate of malignant nodule in cold solid nodule & cold complex nodule group. No difference in the boundary condition, echogenicity & distribution of internal echo existed between benign nodule group &malignant nodule group.

Objectives : The aim of this study is to develop the system and evaluate the optical analytical technique that reflects acupoint pigmentation and extravasated blood by cupping. Methods : We designed the system able to express XYZ coordinate on local skin color. To evaluate measurement-accuracy, we compared with 24 Color Checker Chart by standardized Commission Internationale de l'Eclairage. After confirming the performance of system, we experimented with cupping which was 80 kPa negative pressure for 1 minute on left/right BL13. The X, Y and Z values were converted to R, G and B, $L^*$, $a^*$ and $b^*$, Erythema Index (E.I.), and Melanin Index (M.I). We compared and analyzed two cases on before/after cupping. Results : The R, G and B values which were converted by X, Y and Z values had high linearity as a high level of R-square (R: 0.969, G: 0.996, and B: 0.992). Moreover, we confirmed that it was possible to quantitatively analyzed the change in skin color by cupping using R, G, B, $L^*$, $a^*$, $b^*$, E.I., and M.I. Conclusions : Therefore, we proposed the new analytical technique for objectifying the oriental medical diagnostic method using cupping and optical sensing technique.

Objectives : Poststroke depression is a frequent and specific entity that impaires the rehabilliation and functional recovery of patients with hemiplegia. The author evaluated the effect of Banhahubak-tang(Banxiahoupotang) in patients with poststroke depression. Methods : 38 patients suffering from poststroke depression(determined by Diagnostic and Statistical Manual of Mental Disorders, revised. 3rd edition. and Beck Depression Inventory[BDI] cutoff $point{\geqq}10$) in Kyunghee Oriental hospital were randomized into two groups; treatment group(n=19) and control group(n=19). The treatment group was prescribed with Banhahubak-tang(Banxiahoupotang) three times a day fur a week. Control troop was prescribed with other herbal medicines used for stroke Patients three times a day for a week. Patients were evaluated by use of BDI scale, Modified Barthel Index, Depression of Ki score, Yin syndrome score, and Yang syndrome score. Among 38 patients, 24 patients got BDI scores above 21, which is the cut-off score for depression in Korean. The same procedures and assessments described above were applied. Results : Treatment group did not significantly improve compared with control group. Results yielded only slight significance (P=0.086). Especially. patients with poststroke depression as yin syndrome improved more significantly on BDI than those classified as yang syndrome. When BDI cutoff point for depression was defined as being ${\geq}\;21$, treatment group did not significantly improve compared with control group(P=0.114). However, patients with poststroke depression classified as yin syndrome were also significantly improved on BDI than those classified as yang syndrome. Conclusions : This study suggests that Banhahubak-tang(Banxiahoupotang) is significantly effective in patients with poststroke depression classified as yin syndrome.

Fifty cases of open heart surgery were done in the Department of Thoracic and Cardiovascular Surgery, Busan National University Hospital during 16 months from July, 1981 to October, 1982. The clinical data were analyzed and summerized as follows. 1. There were 34 cases (68%) of congenital anomalies and 16 cases (32%) of acquired heart diseases. Among the congenital cases, 27 were acyanotic and 7 were cyanotic. All of the acquired heat diseases, 16 cases were valvular diseases and they had valvular replacement surgery. 2. The age distribution of the congenital anomalies ranged from 6 to 27 years with mean age of 14.2 years, and the acquired heart diseases from 18 to 44 years mean age of 27.5 years. The difference of sex distribution was no significance. 3. The clinical minifestations in acyanotic congenital anomalies were exertional dyspnea (81.5%), recurrent respiratory infection (55.6%) and palpitation (22.2%), and in cyanotic congenital anomalies were exertional dyspnea (100%), syncope(57.1%) and growth retardation(57.1%), and in acquired heart diseases were dyspnea(100%), edema (62.5%) and general weakness (62.5%) 4. During the cardiopulmonary bypass, mild to moderate core cooling was performed and added topical cooling for more accurate myocardial preservation. 5. Two kinds of cardioplegic solution used in our institute were Bretschneider solution for the first 7 cases and mixed Harmann's solution 1 L with glucose 5gm, potassium chloride 26 mEq and sodium bicarbonate 24 mEq, making 376 mosmol/L and pH 8.3 at $25^{\circ}C$, for the rest 43 cases. 6. Various kinds of postoperative complications occurred in 14 cases (28%) and showed overall mortality 12%. The mortality along with each disease was 7.4% in congenital acyanotic cases, 42.9% in congenital cyanotic cases and 6.3% in acquired valvular diseases. 7. Pre-and postoperative diagnostic incompatibility was seen in 6 cases (12%). 8. The artificial valves used in the replacement surgery were lonescu-Shiley bovine xenograft in 6 cases and Carpentier-Edwards porcine xenograft in 10 cases.

To distinguish reactive mesothelial cells from malignant cells in body fluid, we applied silver staining of nucleolar organizer regions(AgNORs) to ethanol fixed cytologic preparations. Fifty aspirated samples of benign(22 cases) and malignant(26 cases) body fluids were studied using the one step silver staining method. Two cytologically atypical samples were also included in the study. In malignant cases the mean AgNOR count was $3.56{\pm}0.81$, while in benign cases the mean AgNOR count was $2.02{\pm}0.33$. The difference of AgNOR counts between these two groups were statistically significant(p<0.001). The mean of atypical cases was 2.91. Both were diagnosed as malignant in follow-up cytology. In malignant effusions, there is statistically significant difference in AgNOR counts between cells forming complex papillae or clusters and singly scattered cells(p<0.05), $3.29{\pm}0.95\;and\;3.83{\pm}0.55$, respectively. We concluded that AgNOR count appears to be useful as a diagnostic tool especially when the cytologic differentiation is difficult.

Objective : Persistent trigeminal artery variant (PTAV) is an anastomosis between the internal carotid artery (ICA) and the cerebellar artery without any interposing basilar artery segment. We discuss its probable embryological origin and emphasize clinical implications. Methods : Retrospectively 1250 conventional cerebral angiograms and 2947 cranial magnetic resonance angiographies (MRAs) were evaluated for the patients with PTAV. Results : Five patients (four men and one woman, 23 to 76 years of age, median age 65 years) had a PTAV. Three patients who underwent MRA had a PTAV (3/2947=0.1%). Four of the patients who underwent cerebral angiography had a PTAV (4/1250=0.32%). Two of 143 patients who underwent both conventional angiography and cranial MRA showed PTAV. The PTAV was an incidental finding in all five patients. The PTAV originated from the cavernous segment of the left ICA in four patients and from the cavernous segment of the right ICA in one patient. The terminal branch of the PTAV was the anterior inferior cerebellar artery (AICA) and superior cerebellar artery (SCA) in two patients and the AICA only in the other three patients. Conclusion : Neurosurgeons should be aware of possible presence of PTAV. Manipulation of this vessel during a surgical approach to the parasellar region and percutaneous gasserian ganglion procedure may result in hemorrhage or ischemia.

Purpose: To determine the accuracy of visual inspection with acetic acid (VIA) in detecting high-grade cervical intraepithelial neoplasia (CIN) in pre- and post-menopausal women with atypical squamous cells of undetermined significance (ASC-US) and low grade squamous intraepithelial lesion (LSIL) Papanicolaou (Pap) smears. Materials and Methods: Two hundred women (150 pre-menopausal and 50 post-menopausal) with ASC-US and LSIL cytology who attended the colposcopy clinic, Thammasat University Hospital, between March 2013 and August 2014 were included. All women underwent VIA testing and colposcopy by gynecologic oncologists. Diagnostic values of VIA testing including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for detecting high-grade CIN were determined using the histopathology obtained from colposcopic-directed biopsy as a gold standard. Results: VIA testing was positive in 54/150 (36%) pre-menopausal women and 5/50 (10%) post-menopausal women. Out of 54 pre-menopausal women with positive VIA testing, 15 (27.8%) had high-grade CIN and 39 (72.2%) had either CIN 1 or insignificant pathology. Ten (10.4%), 43 (44.8%) and 43 (44.8%) out of the remaining 96 pre-menopausal women with negative VIA testing had high-grade CIN, CIN 1 and insignificant pathology, respectively. Out of 5 post-menopausal women with positive VIA testing, there were 4 (80%) women with high-grade CIN, and 1 (20%) women with insignificant pathology. Out of 45 VIA-negative post-menopausal women, 42 (93.3%) women had CIN 1 and insignificant pathology, and 3 (6.7%) had high-grade CIN. Sensitivity, specificity, PPV and NPV of the VIA testing were 59.4%, 76.2%, 32.2% and 90.8%, respectively (60%, 68.8%, 27.8% and 89.6% in pre-menopausal women and 57.1%, 97.7%, 80% and 93.3% in post-menopausal women). Conclusions: VIA testing may be used as a screening tool for detecting high-grade CIN in women with minor cervical cytological abnormalities in a low-resource setting in order to lower the rate of colposcopy referral.

Background: The relation ofsurvivin gene expression to survival and surgical prognostic factors in the patients with endometrial carcinoma is unclear. Materials and Methods: In this study, 62 cases who were operated due to endometrial carcinoma were investigated between 2003 and 2011 in the the gynecological oncology clinic of Female Disease Training and Investigation Hospital of Etlik Zubeyde, Hanim, Turkey. Clinical and surgical prognostic factors were investigated by screening the records of these cases. With the standard streptavidin-biotin immune peroxidase method, cytoplasmic and nuclear expression of survivin was investigated in sections with specific antibodies (1:100, diagnostic Bio Systems, USA) primer. The aim was to elucidate any relation between survivin expression and defined prognostic factors and survival. Results: There was no statistically significant relationship between cytoplasmic and nuclear indexes identified for survivin and age, body mass index, the levels of preoperative hemoglobin, platelet and Ca 125, stage, grade, lymph node meastasis, the number of meta statical lymph nodes (total, paraaortic and pelvic), myometrial invasion, serosal invasion, adnexal involvement, the presence of acid in the first diagnosis, the involvement of omentum, the adjuvant treatment application of the cases, the presence of recurrence and rate of mortality (p>0.05). Statistical significance was noted for the presence of advanced stage lymph node metastasis (pelvic, paraaortic, pelvic and paraaortic), serosal involvement, positive cytology, lymph vascular space invasion, intra abdominal metastasis, and omentum involvement. When investigated the relation between cytoplasmic and nuclear survivin indexes and total survival, the result was not statistically significant (p>0.05). Conclusions: In our study, there was no statistically significant relationship between the rates of cytoplasmic and nuclear survivin expression with identified prognostic factors and total or non-disease survival.
