To investigate the effect of tumor removal and administration of OK432 on the splenic natural killer (NK) cell activity in the subcutaneous tumor bearing rats, NK cell activity assay using a 4-hour 51Cr release assay and flow cytometric analysis for NK cell population were performed. The results were as follows: 1. Splenic NK cell activity and population in the subcutaneous tumor bearing rats decreased along with the growth of the tumor. 2. The rats with subcutaneous tumor removal showed decrease of splenic NK cell activity, but splenic NK cell population was not decreased. 3. In the rats with subcutaneous tumor removal and OK432 administration, splenic NK cell activity was significantly increased 1 week after administration of OK432 and then gradually returned to normal, whereas increase of NK cell population was not significant. In the present study, splenic NK cell activity was significantly decreased despite removal of subcutaneous tumor. But with the administration of OK432, splenic NK cell activity returned to normal. Considering the role of NK cells on the first line of defense against the metastatic implantation of circulating tumor emboli, we suggest that perioperative administration of immunopotentiator such as OK432 may improve the patient's outcome after surgery of human neoplasm.

To know the prevalence of the diabetes mellitus and associated diseases, we analyzed the date of the 3,088 subjects who were examined with the Computed Automated Medi-Screening Test System which consisted of 65 parameters including blood glucose determination fasting and one hour after 100 g of oral glucose load. We grouped the subjects by the modified criteria of National Diabetic Data Group. Followings are the results of the various analysis: 1. The prevalence of diabetes mellitus and impaired glucose tolerance in 2.27% and 18.26% respectively. 2. The prevalence of diabetes mellitus is 2.63% in male and 1.66% in female. There is no statistically significant difference between male and female. 3. There in tendency of increasing prevalence of diabetes mellitus as the age increases. From second to eighth decade, the prevalence of diabetes mellitus increases as 0.0, 0.45, 0.67, 2.28, 3.47, 5.36, 10.00% respectively. 4. There is no statistically significant difference of prevalence of obesity between normal and diabetes: that is, 18.03%, 22.86% respectively (P≥0.1). 5. There is no statistically significant difference of prevalence of impaired glucose tolerance and diabetes between non-obese and obses group (P≥0.1). 6. There is statistically significant increases of frequency of proteinuria, azotemia, hypertension as the glucose tolerance decreases (P≤0.05).

We report a case of periumbilical pseudoxanthoma elasticum in a 73-year-old female. It is characterized by a dark-yellowish plaque present on the periumbilical area of the lower abdomen. The plaque is well-demarcated and its surface is grooved or fissured, atrophic and verrucoid. This localized lesion of the periumbilical area occurs in a multiparous woman with no history of hereditary systemic pseudoxanthoma elasticum.

A 40-year-old man attended our hospital with presenting symptoms of an acutely swollen, tender testicle and bulging mass on the inguinal area. Considered it as urgent conditions no demonstrating blood flow to the involved testicle on Color Doppler ultrasonography, we underwent scrotal exploration right away. On operative finding the right testis was so enlarged and engorged secondarily to the irreversible ischemic damage, but torsion of spermatic cord was not found. Another inguinal approach revealed herniated mass protruding from internal inguinal ring and compressing the spermatic cord. For further evaluation abdominal ultrasonography and CT scan was done and huge mass occupying right lower quadrant of abdomen and pelvic cavity was noted. The resected tumor through surgical exploration was proved to be a retroperitoneal liposarcoma pathologically. Herein we report an uncommon case of testicular infarct, mimicking torsion of spermatic cord that is a urological emergency, caused by herniated retroperitoneal mass. So the present report suggest that, when adult men attend with symptoms of acutely swollen painful testicle, we pay a more careful attention to patient,s physical findings and recommend further diagnostic evaluation.

We evaluated the availability of Lithoclast in ureteroscopic removal of stone retrospectively. We treated 62 patients(68cases) with ureteral calculi using stone basket or Swiss Lithoclast lithotriptor with the rigid ureteroscope (URS) between December 1993 and February 1995. The success rates of URS were 93%(63/68), and Lithoclast use rates were 77%(52/68). According to stone site, Lithoclast use rates were 68%(28/41) in the lower ureter, 86%(12/14) in the mid, 92%(12/13) in upper ureter respectively. According to stone size, Lithoclast use rates were 50%(4/8) in less than 0.5cm, 75%(30/40) in 0.6-1.0cm, 89%(16/18) in 1.1-2.0cm, 100%(2/2) in above 2.0cm respectively The Lithoclast successfully fragmented stones. There were 5 failures of URS due to failure in access to stone by URS(4 cases), impacted stone(1 case). Reoperation consist of URS in 2 cases, ureterolithotomy in 2 cases and nephrectomy in 1 case. The complications of Lithoclast use URS were insignificant such as gross hematuria(3 cases), infection(2 cases), flank pain(1 case). There were no intraoperative or long term complications directly related to the use of this device. In conclusion, Swiss lithoclast lithotripsy significantly contributed to improve the success rates in treatment of ureteral stone, and is a safe, effective and inexpensive device.
