Clinical and histopathological studies were made on 202 cases of malignancy of cervix, that were visited to the Department of Obstetrics and Gynecology, Yeungnam University Hospital, during 5 years from 1983 to 1987. The results were summarized as follows. 1. Malignancies of the uterine cervix were 10% of total female malignancies. 2. Among 202 cases, 195 cases (96.5%) were squamous cell carcinoma, in which 60 cases (30.0%) of carcinoma in situ, 9 cases (4%) of microinvasive, and 126 cases (62.5%) of invasive carcinoma were included. 3. The average age of the patients with squamous cell carcinoma was 49.4 years old; In case of carcinoma in situ, it was 43.8, microinvasive, 40.0, invasive 52.1 years old. 4. Clinical symptoms of the patient with squamous cell carcinoma in order of frequency were as follows; vaginal bleeding (47.5%), abnormal cytology (15.4%), and abnormal vaginal discharge (9.4%). 5. Duration of the chief complaints was most commonly less than 6 months (73.2%), and the average duration was 3.8 months. 6. The most common age of marriage was between 19 to 22 years old (46.5%). The average was 21.5 years old. 7. The gravity was 51.5% in 5-8 times, and average 6.2 times. The parity was 61.9% in 1-4 times, and average 3.9 times. 8. The subdivision of 126 cases of invasive carcinoma was made according to FIGO stage classification, stage I, 40 cases (31.8%), stage II, 54 cases(42.9%), stage III, 11 cases (8.7%), and stage IV, 8 cases (6.3%). 9. The histologic subtypes of invasive squamous cell carcinoma were distributed as follows; large cell keratinizing type, 25 cases (19.8%), large cell nonkeratinizing type, 101 cases (80.2%). 10. In the cytologic diagnosis, class I was 2 cases (1.9%), class II was 16 cases (15.1%), class III was 33 cases (31.1%), class IV was 31 cases (29.3%), class V was 24 cases (24.6%). 11.

OBJECTIVES: Significant progress has been made in understanding psychosocial, psychological, and environmental factors associated with suicide. However it is only recently that attention has been paid to the understanding of the neurobiology of suicide. The aim of this study was to examine the relationship between platelet serotonin level and suicidal behavior and psychological features of the suicidal attempters. METHODS: After a suicidal attempt platelet serotonin level was measured from 21 patients and compared it with those from depression patients and normal controls. Also MMPI, HAM-D, Barratt impulsiveness scale(BIS) were done to evaluate their psychological features. RESULTS: 1) There was no significant difference in sex ratio of the suicidal attempters. 2) There was no significant difference in platelet serotonin levels among three groups. 3) The analysis of MMPI revealed that the scores of D, Hs, Pt in clinical scales were significantly higher in suicide patients and scores of D, Pa, Si were in depression patients. 4)The HAM-D score was significantly higher in depression and suicide patients, especially in depression patients. 5) The analysis of Barratt impulsiveness scale revealed that the scores of nonplanning, motor and cognitive impulsiveness scale were significantly higher in suicide patients. CONCLUSIONS: There was no significant difference in platelet serotonin levels among three groups. However the analysis of psychological features revealed significant differences. Therefore we concluded that psychological examinations are benefit to evaluate the suicidal tendency.

OBJECTIVES: Polycystic ovary syndrome (PCOS) has the feature of excessive LH, hyperandrogenism and disturbance of folliculogenesis. Also, insulin, IGF-I and IGFBP-1 are involved in the pathogenesis of PCOS. Various surgical and medical therapies have been used and the action mechanisms are related to the endocrine effect. Laparoscopic ovarian electrocautery or laser vaporization is effective in the restoration of ovulation and normal menstrual cycle with minimal invasive procedure especially in the patients resistant to medical therapy. Clomiphen citrate (CC) is used for the ovulation induction in PCOS and the resistance is known to be related to insulin, IGF-I, IGFBP-1 levels. This study was performed to evaluate the effect of the laparoscopic laser vaporization on the levels of LH, FSH, testosterone, IGF-I and IGFBP-1 and on the ovarian response to clomiphen citrate in patients with CC-resistant PCOS. MATERIALS AND METHODS: The fasting basal serum LH, FSH, testosterone, IGF-I and IGFBP-1 level were measured in 10 PCOS patients with CC-resistance and 7 normal controls with regular menstrual cycle. In PCOS, after laparoscopic CO2 laser vaporization, endocrine levels were measured in 1 week interval for 4 weeks and then compared with preoperative levels. RESULTS: In PCOS group, mean serum LH/FSH ratio, testosterone, IGF-I levels were higher and IGFBP-1 level was lower than control. LH/FSH ratio decreased from 2.51+/-0.67 to 1.7+/-0.6 (p<0.05) in 2 weeks, to 0.56+/-0.2 (p<0.01) in 3 weeks and to 1.41+/-0.3 (p<0.01) in 4 weeks after operation. Testosterone level decreased from 1.51+/-0.82 ng/ml to 0.65+/-0.34 ng/ml (p<0.05) in 2 weeks, to 0.56+/-0.67 ng/ml (p<0.01) in 3 weeks after operation. IGF-I level also decreased from 436+/-47.5 microgram/l to 187+/-38 microgram/l (p<0.01) in 1 week, to 167+/-42 microgram/l (p<0.01) in 2 weeks, 179+/-55 microgram/l (p<0.01) in 3 weeks and to 120 +/-43 microgram/l (p<0.01) in 4 weeks after operation. IGFBP-1 level showed no significant change. In 8 of 10 PCOS patients, ovulation was induced with low dose clomiphen citrate. CONCLUSION: Laparoscopic CO2 laser vaporization restores normal menstrual cycle and ovulation through endocrine effect of decreasing LH/FSH ratio, testosterone and IGF-I level and increases the response to CC. Therefore it is useful for restoration of normal menstruation and induction of ovulation in CC resistant PCOS patients.

PURPOSE: To analyze contrast-enhancement pattern of stomach cancer on dynamic MRI and to verify the efficacy of intravenous contrast agent in the evaluation of stomach cancer. MATERIALS AND METHODS: Twelve patients with proven stomach cancer underwent dynamic MRI, By using 1.0T scanner, we obtained precontrast FLASH images, and 30, 60, 90 second delay FLASH images after intravenous contrast injection. All patients ingested on liter of water and had intramuscluar injection of Buscopan just before MR study. For quantitative analysis we measured signal to noise ratio (S/N) of stomach cancer on each image, and signal difference to noise ratio (SD/N) between cancer and intraluminal fluid, cancer and the pancreas. For qualitative analysis two radiologists evaluated lesion conspicuity on each image by grading system(grade 0, 1, 2, 3: poor, fair, good, excellent). RESULTS: S/N of stomach cancer increased gradually by time(precontrast, 30, 60, 90 second delay:38.7, 42.5, 57.4, 65.7). SD/N between cancer and intraluminal fluid significantly increased after contrast enhancement(1.24, 25.01, 39.30, 45.89). SD/Ns between cancer and the pancreas were 10.5, 9.33, 9.99, 10.66 respectively. In qualitative analysis, precontrast images were better than postcontrast images for delineation of stomach cancer, Postcontrast images showed clear endo-luminal side of stomach cancer, but outer margin of stomach cancer was more distinct on precontrast images. CONCLUSION: Precontrast MR images are better than postcontrast MR images in the depiction of stomach cancer. Intravenous contrast agent is not imperative in the evaluation of stomach cancer.

PURPOSE: To verify the usefulness of left portal vein angle (LPVA) on CT scan in the diagnosis of liver cirrhosis and to compare its diagnostic value with that of caudate to right lobe ratio (C/RL ratio). MATERIALS AND METHODS: LPVA, an angle formed by a vertical line and a line connecting the center of the vertebral body to the umbilical point of the left portal vein, and C/RL ratio were measured on CT scans of 100 cirrhotic and 100 normal livers. Diagnostic values of LPVA and C/RL ratio were compared statistically. RESULTS: The mean of LPVA was 18.9 degrees(SD; 7.6) for normal livers and 25.8 degreesSD; 8.4) for cirrhotic livers (P<0.001). The mean of C/RL ratio was 0.47(SD; 1.10) for normal livers and 0.58(SD;0.14) for cirrhotic livers (P<0.001). When LPVA was greater than 30 degreesliver cirrhosis was diagnosed with 36% sensitivity and 92% specificity. When C/RL ratio was greater than 0.60, the diagnose of liver cirrhosis was with 41% sensitivity and 90% specificity. There was no significant difference of the diagnostic accuracy between LPVA and C/R L ratio in ROC analysis. CONCLUSION: Both LPVA and C/RL ratio are useful diagnostic indices of liver cirrhosis on CTscan. LPVA is more convenient to measure than C/RL ratio.

Twenty three patients with locally invasive transitional cell carcinoma of the bladder(stage T2-T4N0M0) who refused to undergo radical cystectomy or were poor surgical candidates were included in this study. All patients received transurethral resection(TUR) of the tumor initially for the pathologic staging and debulking of tumor mass. Then, patients were treated with either one of the following two bladder preservation protocols. First trials consisted of initial 2 courses of MVAC(methotrexate, vinblastin, adriamycin and cisplatin) chemotherapy and followed by radiotherapy( 6480cGy) plus 2 courses of cisplatin. The other protocol was initial radiotherapy ( 6480cGy) with 2 courses of cisplatin and additional 2 courses of MCV(methotrexate, cisplatin and vinblastin) chemotherapy. There were 8 patients in T2, 13 in T3 and 2 in T4. Repeat biopsies were conducted 1 to 6 months after initiation of therapy. With a mean follow up of 17.1 months, other than two patients who underwent cystectomies, the survival rate without local recurrence or distant metastasis was 66.6% (14/21)-87.5 % ( 7/8) in T2. 63.6 % ( 7/11) in T3 and 0%(0/2) in T4. Bladder tumor recurrence and metastasis was observed in 3 patients respectively. One patient in stage T4 died at 20 months with multiple metastasis. The survival rate is closely correlated to initial stage. Patients with no residual mass after TUR seemed to be better in response than patients with residual mass. Side reactions such as neutropenia ( <2000/ mm3) were observed in 6(26.2% ) patients, radiation cystitis in 2(8.7% ) and radiation proctitis in 1(4.3%) The bladder preservation protocol in locally invasive bladder tumor has relatively satisfactory results but longer follow-up is necessary to determine the efficacy of current protocol in long term survival.

In order to develop a method for the detection of minimal residual leukemic disease (MRD) in T cell acute lymphocytic leukemia (T cell ALL), T cell leukemia cell line was used to detect clonal TCR p chain mRNA and to synthesize CDR3 specific oligonucleotide probe. For the Jurkat cell line clonal TCR p chain cDNA was amplified by using RT-PCR with oligonucleotide primer, Vp universal primer. As the result of RT-PCR an approximate 300 bp fragment of the TCR chain was obtained, and the partial identification of the TCR p chain gene and the amino acid sequence of the fragment were done by gene cloning and sequencing. The gene sequence of TCR p obtained was identified as Vp8-Jp1.2-Cp2. Diversity gene segment could not be found. Within the p chain, the CDR3 region was identified as 12 amino acids (SFSTCSANYGYT). It is kown that TCR is expressed in about 40% of the all T cell ALL. However it is not kown what percentage of the TCR p chain mRNA expression translates into the actual TCR molecule. It is not certain how many patients with MRD can be detected by this method used in this study, but this technique might be useful to detect MRD in at least 40% of the patients with T-cell ALL.

For the observation of the histological changes at variable time intervals after estrogen-induced cryptorchidism, we administered different doses of depoestradiol cypionate to 1 week old Sprague-Dawley rats and determined the minimum dose at which the cryptorchidism could be induced in all the rats, and observed the histological changes from 5 weeks after birth at which time the testicular descent into the scrotum normally occurs up to 12 weeks of age, the time of complete maturation. The following results were obtained. l. In cases that the doses above O.2mg of depoestradiol cypionate for each rat were administered cryptorchidism was induced in all the rats but not induced below 0.15mg and all the induced cryptorchidism were bilateral. 2. In the rats to which O.2mg of depoestradiol cypionate was administered, the weight of the testis and the diameter of the seminiferous tubules were significantly decreased compared to those in the control group of rats until 12 weeks after birth. Nevertheless, the rate of increase in these rats was similar to that of the control group. 3. The basement membrane of the seminiferous tubules and Sertoli cells showed relatively few changes. But Leydig cells first appeared in 7 weeks after birth in the estrogen administered group while in the control group the cells continuously appeared after 5 weeks after birth. 4. For the spermatogenesis, in the normal control group, the mature sperms can be observed in 7 weeks after birth while in the estrogen administered group, 12 weeks after birth. The results reveal that the minimum dose at which the cryptorchidism could be induced in all 1 week old Sprague-Dawley rat was O.2mg depoestradiol cypionate for each rat. The spermatogenesis and Leydig cell differentiation in the estrogen administered cryptorchidism were delayed by the effect of estrogen. In addition this study indirectly ascertained that the pathogenesis of unilateral cryptorchidism was not just the deficiency of the gonadotropic hormonal stimulation only. And further observations on the estrogen-administered rats after 12 weeks of age will be required to see whether these histological changes are reversible or not.
