Expression of the pS2 protein in breast carcinoma is a useful guide to evaluate the prognosis and response to tamoxifen. The pS2 protein is an estrogen-regulated 60 amino acid protein which was originally discovered following the screening of cDNA libraries in MCF-7 breast carcinoma cells and is induced through estrogen-dependent transcription of the pS2 gene. The presence of the pS2 protein in breast cancer is considered as valuable as the receptor status, or even more so, in predicting the response to hormonal therapy. We have investigated the pS2 protein expression in 62 cases of primary breast cancer in order to know the relationship between the expression rate of the pS2 protein and hormonal receptor status using immunohistochemical procedures on formalin-fixed and paraffin-embedded tissues. Concomitantly, both the estrogen receptors (ER) and progesterone receptors (PR) were examined using the immunohistochemical technique. Positive staining for the pS2 was seen in forty-nine cases (79%) of the tumors. Forty three cases (88%) of the pS2 positive tumors were ER positive and forty one cases (84%) of the pS2 positive tumors were PR positive ; forty six cases (93%) of pS2 positive tumors were positive for ER and/or PR. The pS2 status correlated significantly with the ER (p<0.0001) and PR (p<0.001). The results reveal a close association between the pS2 protein and either or both the ER and PR status.

Total 481 cases of gallstones from Korean patients operated at Keimyung University Dongsan Hospital during the last 6 years were classified by macroscopic view according to the classification of Sato, et al and reviewed with a special reference to age, sex, and kinds and sites of gallstones. Gallstrones were present predominatly in the age of 50-60 years, the average 52. Sex ratio (M:F) was nearly equal, being 1:1.05. Gallbladder was the most frequent site, comprising 53.2%, followed by common bile duct, 23.3% and intrahepatic location, 3.7%. Macroscopic classification revealed pigment gallstones in 53.0% (calcium bilirubinate, 41.8%; black, 11.2%); cholesterol gallstones in 36.2%, of which mixed stone being 33.1%. Cholesterol gallstones occurred predominantly in 50-60 years of age with a prediletion to females. On the contrary, elderly persons more than 60 years of age had calciu bilirubinate stones. No sex difference was found in the calcium bilirubinate stones. Eightly-six percent of cholesterol gallstones were present in the gallbladder only. Common bile duct stones were mostly composed of pigment gallstones in 80.4%.

Two unusual and rare forms of Brenner tumor are reported and the literatures are reviewed. The one, "proliferating" Brenner tumor, morphologically resembling low grade papillary transitional cell carcinoma of urinary bladder and regarded as a third variant intermediate between the benign and malignant forms; the other, malignant Brenner tumor of right ovary, corresponding to grade III transitional cell carcinoma of urinarybladder with areas of invasive squamous cell carcinoma and benign Brenner tumor of left ovary, combined with bilateral cystic teratomas. These tumors give additional support to the concept that Brenner tumors are composted of epithelium of urinary tract(urothelial) type.

The study was undertaken to assess the CT density of the antibiotics solution. CT scan of six antibioticssolution-streptomycin, chloramphenicol, Na-penicillin, ampicillin, kanamycin and cefamezine-in concentration ofabout 33% (approximatly single dose of intramuscular injection) was performed, using plastic syringes. Variousconcentrations of striptomycin, chloramphenicol and Na-panicillin were also examined for evaluation of relationbetween concentration and the CT density of the antibiotics. In addition, relationship between CT number andmathematically calculated effective atomic number and electron density of the antibiotics was evaluated. Theresults are as follows; 1. The CT densities of all antibiotics reveal high density (CT number 80–150) inconcentration of single intramuscular injection dose. 2. CT number of striptomycin, chloramphenicol andNa-penicillin gradually increased with increase of concentration of the antibiotics, producing linear proportionto concentration, effective atomic number and electron density of the antibiotics. 3. Therefore, density ofantibiotics should be included in differential diagnosis when high density on CT scan is observed.

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

The authors introduced flip back spin echo (FBSE) technique for MR imaging of the temporomandibular joint (TMJ) instead of conventional spin echo (SE) technique, and evaluated whether FBSE technique in MRI of TMJ is adequate for the diagnosis of the disorders or not. FBSE T1 parasagittal images in closed mouth state and sequential opening and closing mouth states using patient's own finger(s) were obtained and then FBSE T1 paracoronal image in closed mouth state and STAGE(short tip angle gradient echo) parasagittal T2WI were followed. All 30 images of the symptomatic TMJs using FBSE technique were excellent in the visualization of articular and their displacement, and we could easily diagnose the internal derangement. FBSE technique was adequate for the diagnosis of internal derangement of the TMJ, and the modified cine display from images using FBSE technique was advantageous in the diagnosis of the disorders by visualization of the dynamic motion of the TMJ.

Experiments were conducted to define the optimal constituents of culture medium and atmospheric condition for growth of Campylobacter pylori. Two clinical isolates were streaked onto various media, incubated in two different atmospheric conditions (microaerophilic condition and carbon dioxide incubator), and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on Campy media, composed of GC agar base plus 1% hemoglobin, 0.2% activated charcoal, 1% IsoVitaleX, vancomycin 6mg /L nalidixic acid 20mg/L and amphotercin 2 mg/L, was used as reference. Our conclusions were as follows: Tryptic soy agar base was not acceptable for the growth of C. pylori. The organism grew in both atmospheric conditions, but generally showed a scantier growth in the carbon dioxide incubator than under the microaerophilic condition, however GC agar containing 1% hemoglobin and 0.2% activated charcoal supported well the growth of C. pylori in the carbon dioxide incubator. The authors have found that the GC agar base supplemented with 1% hemoglobin and 0.2% charcoal was the most satisfactory medium and a microaerophilic condition was optimal atmospheric condition for the growth of Campylobacter pylori in this study.

Thirty three cases of metastatic ovarian carcinoma were analysed cilincopathologically. The patient's age ranged from 20 to 68 years, the average being 44.3. Most ovarian tumors were bilateral and asymmertically enlarged, firm and occsaionally multicystic. Histologic examination revealed adenocarcinoma in 31 cases, of which Krukenberg tumors in 14; squamous cell carcinoma in 2. The most common primary site was gasrtointestinal(75.8%), followed by genital, breast and gallbaldder. Most Krukenberg tumors were originated from poorly differentiated adenocarcinoma of stomach. The ovarian and primary carcinomas were synchronously diagnosed in 15 cases, while in 3 cases the primary carcinoma was not round until the ovarian tumor had been removed.

OBJECTIVE: To compare the clinical outcomes of intrauterine insemination (IUI) according to the catheter used. MATERIALS AND METHOD: From March 1998 to September 1998, total 95 infertile patients were included in this study. Patients were randomly allocated to TomCat group (n = 39) and Mackler group (n = 56) according to the catheter for insemination. The controlled ovarian hyperstimulation (COH) using luteal long protocol of gonadotropin releasing hormone agonist (GnRH-a) was used in all patients. Statistical analysis was performed using Student's t-test, Fisher's exact test, and x2 test as appropriate. Statistical significance was defined as p < 0.05. RESULTS: The total dose and duration of exogeneous gonadotropin required were similar between the two groups. There were also no significant differences in serum estradiol (E2) level, endometrial thickness and texture on the day of hCG administration between the two groups. However, the percentage of uterine souding due to failure of initial approach was significantly higher in TomCat group compared to Mackler group (23.1% vs. 0%, p < 0.01). The percentage of bleeding after IUI in TomCat group seemed to be higher than that in Mackler group (15.4% vs. 3.6%, p = 0.06), although there was no statistically significant difference between the two groups. There was also no significant difference in the clinical pregnancy rate per patient between the two groups. CONCLUSION: These results suggested that using Mackler catheter might be effective for IUI, especially for the patients with cervical factor infertility.
