To evaluate the structural characteristics that might be related to the clinical features noted in preeclamptic patients with focal segmental glomerulosclerosis(FSGS), we analyzed post-partum renal biopsies of 8 preeclamptic patients with FSGS (group 1) by morphometry and glomerular studied the structural-functional relationships. These findings were also compared with those from three postpartum cases with minimal change lesion(group 2) and normal age-matched women(group 3). Mean glomerular volume (MGV) in group 1 and group 2 was (2.64 +/- 0.49) x 10(6) micrometer3 and (2.56+/-0.25)x 10(6) micrometer3, respectively. MGV in both groups was significantly increased compared with that of the control group [(1.11+/-0.22)x10(6) micrometer3](p<0.0005). The volume density of the mesangium/glomerulus [Vv(mes/glom)] in the group 1 patients was significantly increased (p<0.0001) when compared with that of the group 2 and the control group patients. The increment of Vv(mes/glom) was related to both the mesangial cell proliferation and expansion of mesangial matrix. The volume density of the capillary lumen/glomerulus [Vv(cap/glom)] in group I was significantly decreased(p<0.0001) when compared with that of group 2 and the control group. Vv(cap/glom) was directly related to Ccr in group l(r=0.70, p=0.05). These results suggest that reduced capillary luminal area caused by mesangial interposition is related to the decreased glomerular filtration rate in preeclamptic FSGS.

Eight species of Marssonina parasitic on 21 species of host plants from Korea are described and illustrated. They are Marssonina brunnea (Ellis & Everh.) Magnus, M. capsulicola (Rostr.) Magnus, M. celastri H.D. Shin & H.T. Lee, M. coronaria (Ellis & Davis) Davis, M. fragariae (Lib.) Kleb., M. juglandis (Lib.) Magnus, M. rosae (Lib.) Died. and M. sennenis (Gonz. Frag.) Vassiljevsky & Karak. Of these, M. capsulicola and M. coronaria sometimes poss three-celled conidia and M. sennenis is characterized by a short appendage at the basal end of the conidia. Morphological features of conidia and host ranges were of taxonomic values for species delimitation.

It is likely that the peroneus longus tendon acts as a structure resisting the varus force upon the first column of the foot. Our study was designed to examine the possibility that absence of the peroneus longus insertion into the first metatarsal and first cuneiform will destabilize the first metatarsal. The fresh frozen cadaveric specimens of the lower leg were obtained. There were six right feet. The specimens appeared normal visually and roentgenographically. The tibial remnant was rodded by an intramedullary rod and the sprcimen was positioned in a specially designed rig so that standing position of the foot was simulated. The tibia was then loaded with twenty pounds. To obtain reproducible radiographic landmarks radioopaque beads were implanted underneath the level of the cortex through small drill holes in the following location : First metatarsal (one bead in the head, another bead in the base). The second metatarsal (again one bead in the head, on e bean in the base). To simulate the contraction of the peroneus longus muscle a suture was placed into the proximal end of the tendon, brought through two pulleys and loaded with a five pound weight. To create a varus force on the first metatarsal a stab incision was made over the base of the first metatarsal at its medial aspect and a suture was passed through the base of the first metatarsal. The suture was guided over a pulley and loaded with ten pounds. The second metatarsal head was fixed to the bottom of the rig with a smooth Steinmann pin. At this point an AP roentgenogram was taken of the footto assure proper positioning of the foot. Thereafter, the soft tissue between the first and second toe were cut sequentially : (1) Transection of the skin of the first web space both dorsally and plantarly. (2) Transection of the adductor hallucis tendon and the intermetatarsal ligament. (3) Transection of the peroneus longus tendon at its insertion. Each step in the transaction of the soft tissues was followed by another X-ray examination. In each roentgenogram the proximal and distal beads in the first and second metatarsal were connected by a line and the angles between those lines were measured. The results were statistically analyzed with the Friedman Chi square test between each step of the ten feet. Following the first and second step angular changes are not significant. Following the final step, adding release of the tendon insertion of the peroneus longus, the angle changes from 15.95 to 20.55 degrees (difference 4.60 degrees) and this is significant (p < 0.05).

OBJECTIVE: To evaluate the safety and efficacy of the silicone ring pessary in the management of pelvic organ prolapse. METHODS: This study was evaluated for the clinical analysis of 58 pelvic organ prolapse patients who visited our hospital and weared silicone ring pessary from January 1997, to December 1998. RESULTS: Among 58 patients, failure rate was 13.7%(8/58) and complication rate was 50%(29/58). Main causes of failure were vaginal ulcer(4 cases) and recurrent falling out of pessary(3 cases). Most common problems were recurrent falling out of pessary(10 cases) and vaginal erosion with or without ulcer(9 cases), vaginitis(6 cases). There was no significant difference of failure rates and complication rates between hysterectomized patients and the non-hysterectomized patients. CONCLUSION: In management of pelvic organ prolapse which unsuitable for operation, pessary is noninvasive, simple and effective alternative method.

Incarceration of the gravid uterus is a rare but serious complication of pregnancy. Reported is the case of a gravid 2, para 0, abortus 1 with known uterine subserosal myoma(5.3 x5.5cm sized) 26-year-old woman presented with acute dysuria and urinary retention. The patient was 14 weeks and 3 days pregnant and presented several week history of urinary frequency and sensation of incomplete bladder emptying. Examination revealed a retroflexed uterus with cervical opening pointing toward the anterior abdominal wall. An ultrasound revealed a thin, elongated maternal bladder and a uterus incarcerated between the sacral promontary and the pubis. The incarceration was successfully reduced by tenaculum traction of the cervical posterior lip without surgical intervention and had a normal infant of appropriate weight at term.

Two cases of ectopic kidney were reported in conjunction with review of literatures. The ectopic kidneys, measuring 13 cm-,15 cm in length of their ureter, were located between the L3 .and S1. Operative removal of the ectopic kidney disclosed aberrant arteries in their both pole. histological examination revealed normal findings.

Tumor angiogenesis has been found to have prognostic significance in many tumor types for predicting an increased risk of metastasis. We assessed tumor vascularity in 28 cases of borderline malignancy and 71 cases of carcinoma of the ovary which had been resected and diagnosed, using the highly specific endothelial cell marker CD34. The numbers of microvessels were counted in 200 magnification in three highly vascularised areas. The numbers of microvessels in carcinomas were higher than that in the borderline malignancy of serous and mucinous tumors. The number of microvessels of mucinous carcinomas was significantly higher than that of serous carcinomas. There were neither significant differences in the number of microvessels according to histological tumor types (p=0.075) nor significant differences in the number of microvessels according to FIGO stages (p=0.072). But in serous carcinomas, the number of microvessels was higher in the FIGO III-IV stage than in the FIGO I-II stage (p=0.017). This study showed higher neovascularization in malignant tumor than borderline malignancy, and in the advanced stage (FIGO III-IV) than less advanced stage (FIGO I-II) of serous carcinomas.
