1.Differential Diagnosis of Submandibular Gland Lesions by CT.
Journal of the Korean Radiological Society 1994;31(1):1-6
PURPOSE: We designed this study to determine the potentiality of the conventional CT in the diagnosis of submandibular gland lesions, especially in solving the diagnostic difficulty between neoplasm and inflammation. MATERIALS AND METHODS: We performed retrospective study of 35 patients and 2 of them had bilateral lesion of chronic inflammation, hence we analysed 37 cases of submandibular gland lesions. There were 9 cases of tumor (including 1 basal cell carcinoma, and 8 pleomorphic adenomas), 22 cases of chronic inflammation, and 6 cases of acute inflammation. CT scans were evaluated for the degree of enlargement (graded as iso, mild or marked enlargement), pattern of contrast enhancement, contour deformity of the gland, and several other items. RESULTS: Neoplastic masses showed more marked enlargement of the gland (77%) than chronic inflammation (22%). Degree of enhancement showed no difference among the lesions. Enhancement pattern was more inhomogeneous in neoplasm (80%) than in chronic inflammation (5%). Deformity of the natural contour of the gland was more frequent in neoplasm (all of 9 cases) than in chronic inflammation (32%). Acute inflammation showed internal low attenuation probably by abscess formation (3/6 cases) and overlying soft tissue swelling (all of 6 cases), and the age of patients was characteristically younger than other diseases (mean, 9 years). Several findings were more specific to diseases, such as dystrophic calcifications to pleomorphic adenoma (37%) and calculi with or without ductal dilatation to chronic inflammation (45%). CONCLUSION: Pre and postcontrast enhanced CT scan can serve as a predictor of pathologic nature of the submandibular gland lesions.

The most common ocular finding of the idiopathic thrombocytopenic purpura(ITP) is superficial retinal hemorrhages in both eyes. But the descriptions of new vessel on the optic disc(NVD) associated with ITP are scarcely found in literatures. A 17-year-old girl who managed for ITP complained of visual distrubance of the right eye and floaters of the left eye. On fundoscopy the right eye was failed to examine due to thick vitreous hemorrhage and the left eye showed NVD and preretinal hemorrhage. After panretinal photocoagulation of the left eye, NVD was regressed.

Partial Trisomy of 3p (Trisomy of 3p2, dup (3) (p23-->pter)) is a characteristic syndrome of chromosomal duplication of distal part of 3p, but breakpoints seem to vary in location. This syndrome shows multiple congenital anomalies with severe mental retardation, characteristic craniofacial change and absence of other gross external abnormalities. The craniofacial dysmorphism includes frontal bossing and temporal indentation, square face, marked hypertelorism, thick and short nose, full lips and a large mouth with downturned corners. Congenital heart defect, most frequently ASD and VSD, are found in most patients. In the majority of patients, the 3p2 duplication is the unbalanced product of a parental autosomal translocation involving 3p2 and another chromosome. We report a case of female baby who has facial dysmorphism, ASD and hyptonia and was found to have 3p2 duplidation (46XX-9, +der(9)t (3:9)(p23:p24)) by chromosomal analysis. Also we found her father was a carrier of blanced translocation of 3p2 and chromosome 9p (46XY, t(3:9)(p23:p24)).

OBJECTIVE: To assess the effect of recombinant human leukemia inhibitory factor on in vitro development of 1-cell ICR mouse embryo. MATERIALS AND METHOD: ICR mice were superovulated with PMSG/hCG and 1-cell stage mouse embryos were recruited. 1-cell mouse embryo were cocultured on human oviductal cells in a CO2 incubator (coculture group) and were cultured on 0.4% BSA+HTF media (control group). And anti-hLIF Ab was added the cocultured group in a different concentration (1pg, 10pg, 100pg, 1ng) and developmental rate was compaired to the control group, and rhLIF was added to the preincubated 0.4% BSA+HTF media in a different concentration (2000U, 1000U, 100U, 10U) and its developmental rate was compaired to group which was cultured on 0.4% BSA+HTF media only. RESULT: 1. The cleavage rate of 2-cell mouse embryo co-cultured with human tubal epithelial cell was significantly higher than that of cultured with media alone (HTF with 0.4% BSA) (p<0.05). 2. When LIF antibody was added to the medium with human tubal epitherlial cell, the mouse embryo could not cleave more than 2-cell in 1 ng of LIF antibody, and less than 1 ng, the cleavage rate was lower than cultured without LIF antibody group(p<0.05). 3. Two cell blocked ICR mouse embryos were developed into four cells under LIF(p<0.05), but no further development was observed. CONCLUSIONS: These results shows that LIF enhances the development of preimplantation embryo, and when rhLIF is applicated in vitro, it has positive effects on the development of early mouse embryo and can help overcoming the two-cell block.

7.Pathophysiology and Treatment Guidelines of Dysfunctional Uterine Bleeding.
Korean Journal of Obstetrics and Gynecology 2005;48(6):1390-1401
Dysfunctional uterine bleeding (DUB) is the major cause of heavy menstrual bleeding during reproductive years and impacts on women's health both medically and socially. The pathophysiology of DUB is largely unknown but occurs in both ovulatory and anovulatory menstrual cycles. Medical treatments include tranexamic acid, nonsteroidal antiinflammatory drugs, combined oral contraceptives, progesterone, danazol, and GnRH analogue. Surgical treatments include endometrial ablation and hysterectomy. Since none of the treatments for DUB is superior to one of the others, and since all treatments have their advantages and disadvantages, counselling and management of patients with DUB should incorporate medical approach, levonorgestrel releasing IUD, endometrial ablation and hysterectomy.

OBJECTIVE: To establish the evaluation system of the quality of oocytes on the basis of the incidence of cumulus cells apoptosis, to investigate the relationships between the incidence of cumulus cells and the outcomes of IVF-ET. METHOD: Thirth-four cycles undergoing controlled ovarian hypersimulation for IVF-ET with tubal infertility (23 cycles) or unexplained infertility (11 cycles) were included in this study. Cumulus cell masses surrounding mature oocyte and co-culture of embryos with autologous cumulus cells during IVF-ET process. The incidence of apoptosis in cumulus cells was assessed by apoptosis detection kit fluorescein. The effect of co-culture using cumulus cells and the incidence of cumulus cells apoptosis. RESULTS: The results were as follows: 1. The incidence of apoptosis in cumulus cells markedly increased in patients aged 40 or over, while the fertilization rate was greatly decreased in those age group. 2. Apoptosis in cumulus cells was found in both the fertilized oocytes and unfertilized oocytes, but the incidence of apoptosis was higher in unfertilized oocytes. 3. There is no clear correlation between apoptosis in cumulus cells and the number of oocytes retrieved. However, the incidence of apoptosis was increased when the number of oocytes retrieved was 5 and fewer in comparison with 6~10. 4. Embryo grade was significantly affected by the incidence of apoptosis in cumulus cells. 5. Pregnancy rate of IVF-ET per cycle was 29.4%, and the pregnant group had the higher fertilization rate and a significantly lower incidence of apoptosis in cumulus cells compared with the nonpregnant group. 6. When cumulus cells were used as helper cells in the co-culture of the embryo, in vitro activity of cumulus cells based on morphological change and proliferation did not influence the quality of embryo, but was closely associated with the implantation rate and pregnancy rate, which was enhanced when morphological changes and proliferation of cumulus cells was more active. 7. This difference in the outcome of IVF-ET according to in vitro activity of cumulus cells used for co-cultue was not associated with the incidence of apoptosis in cumulus cells, but rather had likely relations with the different secretion pattern of protein, which may be an embryotrophic factor by cumulus cells. CONCLUSION: These results suggest that the incidence of apoptosis in cumulus cells can be used in predicting oocyte qualities and the outcomes of IVF-ET. And the effect of co-culture largely depends on the in vitro activity of cumulus cells as well.

9.Treatment of Korean Vivax Malaria in Korea.
Journal of the Korean Medical Association 2007;50(1):88-92
Although it is not certain when malaria began to appear in the Korean peninsula, it is believed to have had been an endemic disease until 1984. Vivax malaria reemerged in the Republic of Korea (ROK) in 1993. In the early period most of the cases occurred among soldiers stationed in the DMZ and the adjacent region. In order to cope with malaria, the soldiers at risk received chemoprophylaxis with chloroquine and primaquine. The regimen for the treatment of vivax malaria in Korea was established in 1950's. Primaquine was introduced in 1951, and the field testing during the Korean War demonstrated that the combination of three days of chloroquine administration with fourteen days of primaquine reliably prevented the recurrence of vivax malaria. The regimen has been used since then, but there were some controversies as to whether or not to start chloroquine and primaquine on the same day. Most of the current treatment guidelines recommend the use of primaquine for fourteen days to overlap with blood schizonticide agents such as chloroquine and routine tests for G-6-PD deficiency before use. Previous data showed that the G-6-PD deficiency rate has been found very low among Koreans. Thus, it is not always necessarily mandatory to test for G-6-PD deficiency among Korean patients.

The purpose of this study was to determine the frequency of chromosomal or genetic causes of primary amenorrhea, and was made to assess the etiology of disorders in those patients whose chromosome appeared normal. Sixty eight patients with primary amenorrhea were evaluated clinically and cytogenetically, which were refered to our Cytogenetic Laboratory in Department of Obstetrics and Gynecology, Pusan National University Hospital, from Aug. 1988 to Dec. 1996. The results were as follows. l. Out of 68 cases with primary amenorrhea, 40 cases (58.9%) had the normal chromosome constitutions and 28 cases (41.1%) had the abnormal chromosome constitutions including 46, XY. 2. Turner's syndrome was found in 25 cases (36.7%), consisting of 11 cases (16.1%) of 45, X, 3 cases (4.3%) of 46, X, i (Xq), 1 case (1.5%) of 46, X, inv (X), 1 case (1.5%) of 46, X, del (Xq), 1 case (1.5%) of 46, X, del (Xp), 1 case (1.5%) of 46, X, tel (Xq), 1 case (1.5%) of 45, X/46, XX, 1 case (1.5%) of 45, X/46, XY, 1 case (1.5%) of 45, X/47, XXX, 2 cases (2.9%) of 45, X/46, X, del (Xq), I case (1.5%) of 45, X/46, X, del (Xq), 1 case (1.5%) of 45, X/46, X, r (X). 3. 3 cases (4.3%) had the 46, XY chromosome constitution consisting of 2 cases (2.9%) of testicular feminization syndrome and 1 case (1.5%) of pure gonadal dysgenesis. 4. Among 40 patients whose chromosome are normal, the etiologies of amenorrhea were assumed to be caused by 11 cases (27.5%) of hypogonadotropic hypogonadism (idiopathic), 10 cases (25.0%) of congenital absence of vagina, 5 cases (12.5%) of pure gonadal dysgenesis in order of frequency.
