Abnormal offsprings from balanced translocation carriers usually inherit only one of the translocated products and are therefore partially trisomic for one chromosome and partially monosomic for another. Partial trisomy 1q usually demonstrates fetal growth restriction and anomalies of head, face, urogenital tract, heart, finger and toes with a wide range of characteristics and severities. It has been reported in a few individuals in the world and this is the first report of partial trisomy 1q in Korea. We present the case of recurrent partial trisomy 1q in maternal balanced translocation which was prenatally diagnosed by amniocentesis with fluorescence in situ hybridization(FISH) based on abnormal ultrasonographic findings and poor obstetric history.

This experiment was undertaken in order to know the effect of leucocytes on the maturation of mouse oocytes in vitro. Leucocytes obtained from heart puncture of mouse (3 X 10(4) cells/mm3) inhibited the maturation of mouse oocytes. The egg toxic activity declined with decreasing leucocyte concentration. It was found that egg toxic effect of leucocytes is not species specific. The activity of intact leucocytes or equal numbers of leucocytes that were destroyed was similar and which seems not to be influenced by the physiological stats of leucocytes.

We report a case in which CT scanning revealed lipohyperplasia of the ileocecal (IC) valve and cecum with acute inflammation and ulceration mimicking malignant neoplasm. At unenhanced CT, lesion attenuation was lower than that of back muscle, and at contrast-enhanced CT, the lesion was seen as a lobulated polypoid mass with inhomogeneous enhancement, pericecal fat infiltration, and pericecal lymphadenopathy. Although these findings mimick those of malignant neoplasm, the typical location of the mass, involving the IC valve, and the low attenuation observed at unenhanced CT, can help distinguish it from other masses.

Pulmonary lymphangioleiomyomatosis is a disease involving the proliferation of atypical smooth muscle cells trom the perilymphatics, peribronchial and perivascular region of the lung and the retroperitneum. The disease usually affects women of child-bearing age. We recently experienced a case of pulmonary lymphangioleiomyomatosis in a 31-year-old women who had suffered from a chylous pleural effusion. Histologic confirmation of lymphangioleiomyomatosis was made upon a video-associated thoracoscopic lung biopsy. Here we report this case with a brief review of the literature.

BACKGROUND: The accentuated nitric oxide (NO) release that is induced by the systemic inflammatory response associated with infective endocarditis (IE) and cardiopulmonary bypass (CPB) may result in catecholamine refractory hypotension (vasoplegia) and increased transfusion requirement due to platelet inhibition. Methylene blue (MB) is an inhibitory drug of inducible NO. We aimed to evaluate the effect of prophylactic MB administration before CPB on vasopressor and transfusion requirements in patients with IE undergoing valvular heart surgery (VHS). METHODS: Forty-two adult patients were randomly assigned to receive 2 mg/kg of MB (MB group, n = 21) or saline (control group, n = 21) for 20 min before the initiation of CPB. The primary end points were comparisons of vasopressor requirements serially assessed after weaning from CPB and hemodynamic parameters serially recorded before and after CPB. The secondary endpoint was the comparison of transfusion requirements. RESULTS: Two patients in the control group received MB after weaning from CPB due to norepinephrine and vasopressin refractory vasoplegia and were thus excluded. There were no significant differences in vasopressor requirements and hemodynamic parameters between the two groups. The mean number of units of packed erythrocytes transfused per transfused patient was significantly less in the MB group. The numbers of patients transfused with fresh frozen plasma and platelet concentrates were less in the MB group. CONCLUSIONS: In IE patients undergoing VHS, prophylactic MB administration before CPB did not confer significant benefits in terms of vasopressor requirements and hemodynamic parameters, but it was associated with a significant reduction in transfusion requirement.

BACKGROUND: The combination of local anesthetics and opioids in the spinal anesthesia has a synergic analgesic effect. Therefore, we compared intraoperative conditions and clinical effects of low dose (5 mg) bupivacaine added with fentanyl versus a conventional dose(10 mg) of bupivacaine in spinal anesthesia for a transurethral resection of the prostate (TURP). METHODS: Forty five ASA class 1 and 2 patients scheduled for a TURP were randomly divided into three groups. Group B (n = 15) received bupivacaine 10 mg, group BF (n = 15) received bupivacaine 5 mg added with fentanyl 20microgram, and group BFE received bupivacaine 5 mg added with fentanyl 20microgram and 0.2 mg epinephrine. Blood pressure and heart rate were recorded every 5 minutes before and after spinal anesthesia. Sensory blockade was measured by a pin-prick test and motor blockade was evaluated by the Bromage motor scale. Side effects including pruritus, nausea, vomiting, respiratory depression, and intraoperative pain were observed. RESULTS: The duration of sensory and motor blockade in group BF was significantly shorter than in group B and group BFE (P<0.05). Without statistical significance, hypotension (6.7%) and bradycardia (13.3%) were observed in group B and pruritus (26.7%) and nausea (13.3%) occurred in all patients who received fentanyl. CONCLUSIONS: The addition of fentanyl 20microgram to low dose bupivacaine 5 mg resulted in short lasting motor and sensory block, compared with conventional dose bupivacaine 10 mg. Therefore, we concluded that the clinical application of this method could provide adequate analgesia with early discharge and no serious side effects for TURP patients.

BACKGROUND/AIMS: Pancreatic cancer has a very poor prognosis, and early diagnosis is a way to increase the survival rate of patients. The purpose of this study was to develop pancreatic cancer-specific peptides for imaging studies. METHODS: Three pancreatic cancer cell lines, MIA PaCa-2, UACC-462, and BxPC-3, and a control cell line, CCD841, were used. Biopannings were performed on MIA PaCa-2 using a phage display library. After this, the peptides were synthesized and labeled with fluorescein isothiocyanate (FITC). Immunocytochemistry (ICC), enzyme-linked immunosorbent assay (ELISA), and fluorescence-activated cell sorter (FACS) were performed to examine the specific binding. To examine its therapeutic applications, a photosensitizer, chlorin e6 (Ce6), was conjugated on the peptide and photodynamic therapy was performed. Cell survival was investigated using a [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] assay. RESULTS: After three biopannings, the phages were amplified from 1.4×104 to 3.2×105 plaque-forming units. The most strongly binding phage was selected from the ELISA and ICC results. FITC-labeled peptide, M5, in the three pancreatic cancer cell lines showed significantly higher immunofluorescence in the ICC experiments than that of CCD841. The higher binding ability to MIA PaCa-2 cells was confirmed from FACS analysis, which showed a right shift compared to CCD841. M5 bound to Ce6 showed a significantly lower cell survival rate than that of Ce6 alone in photodynamic therapy, which was observed consistently as a change in the tumor size and fluorescence intensity in MIA PaCa-2 cell-implanted animal models. CONCLUSIONS: This study showed that the noble peptide, M5, binds specifically to the pancreatic cancer cell line, MIA PaCa-2. The M5 peptide has potential use in future optical diagnostic and therapeutic purposes.

This study surveyed and measured the level and structure of cancer deaths and their trends over time for offering the fundamental data of the cancer prevention and control in Pusan city in the future. Authors conducted the study of descriptive epidemiology using materials derived from the computerized data of total 3,722 certified cancer deaths in Pusan city from January 1 to December 31, 1993 registered on the National Statistical Office, the Republic of Korea. The obtained results were as follows: 1. According to the total registered cases of deaths(16,331 cases) in Pusan city during 1993, cancer(3,722 cases) and cerebrovascular disease(2,718 cases) were the first and second cause of deaths as 23.1% and 16.9%, respectively. These pattern showed the change between cancer(14.7%) and cerebrovascular disease(18.5%) in order of frequency in comparison to 1982. Also, the total number of cancer deaths was increased in comparison to 1982. The rate of death certification by physicians was 87.1% of all registered deaths, which was increased to 6.8% in comparison to 1982(80.3%). 2. Crude death rate and cancer specific death rate was 4.06 per 1,000 populations and 93.8 per 100,000 populations(male:117.8, female:70.0), respectively. The former was similar to that of 1982, but the latter was increased to 1.6 times as that of 1982. 3. Age-adjusted cancer specific death rate by standardization with whole country population was 111.9(male:141.5, female:106.7) per 100,000 populations, higher than not age-adjusted cancer specific death rate(93.8), and the sex difference was statistically significant with male predominance(p<0.05). 4. Cancer specific death rate by age was generally increased with age and most of cancer deaths(male:91.8%, female:88.5%) occurred since 40 years old. 5. The major cancer(cancer specific death rate per 100,000 populations) in male was liver(30.6) followed by stomach(25.6), lung(21.9), and GB and EHBD(5.7), in female stomach(15.7), liver(9.9), lung(7.3), and uterus(6.9). The relative frequency of the leading three cancer among total cancer deaths marked 66.3% in male and 47.1% in female, and decreased in comparison to 1982(male:72.2%, female:54.5%). 6. The total ratio of male to female cancer specific death rate showed 1.68 to 1 with male predominance. And the ratio was above 2.0 in larynx, oral cavity & pharynx, esophagus, liver, lung, bladder cancer and the ratio was 1.0~1.9 in stomach, pancreas, gall bladder and EHBD, brain, rectum and anus cancer, leukemia, but the ratio was reversed in thyroid and colon cancer. In conclusion, cancer was the first cause of deaths. The proportion of lung cancer was increased, that of stomach & uterine cancer was decreased relatively, and liver cancer was constantly higher proportion. In the future, it is necessary to conduct the further investigations on the cancer risk factors considering areal specificity.
