OBJECTIVES: The purpose of this study was to determine whether or not the shed endometrial tissues in menstrual fluid (MF) have adhesive potentials, using human amniotic membrane (AM). METHODS: The MF from 20 patients with regular menstruation was collected with Wallace catheter by aspiration from the uterine cavity on the second or third day of the menstrual period. The AM was obtained from the placenta of term delivery without any complication. The MF was washed and diluted fivefold with Hams F-10 medium supplemented with 10% fetal bovine serum. The cell suspension was placed on either epithelial layer (EP) or extracellular matrix layer (ECM) of the AM. After 5 days of culture, the adhesion sites were observed under a stereomicroscope. For histological observation, each cultured AM was prepared for the serial paraffin section. RESULTS: The adhesion sites of endometrial tissues in MF were found both ECM (20/20) and EP (11/20) of the AM. The size of adhesion sites in each AM were highly variable from microscopic to macroscopic size. CONCLUSION: We found that the shed endometrial tissues in MF have adhesive potential to epithelial layer in addition to extracellular matrix layer of amniotic membrane. This adhesive potential may be related to pathogenesis of endometriosis. We suggest that this culture system can be useful as an in-vitro model for endometriosis.

Rheumatic fever with renal involvement is rarely seen. The prevalence is found to be low although it may differ by reporters. We report a case of rheumatic fever with IgA nephropathy. The patient was a 14-year-old male. The patient's chief complaint were fatigue and gross hematuria. On the physical examination, the pansystolic murmur (grade II) on the left lower sternal border was noted. Cardiomegaly was seen on chest X-ray and pulmonary vasculatures were increased. Prolonged PR intervals were found on EKG. Echocardiogram showed rheumatic carditis with grade mild to moderate MR, regurgitant shunt from LV to LA through anterior leaflet. On the laboratory findings, ESR, CRP and ASO were increased, C3, C4 and IgA were normal. On the urine analysis, gross hematuria was noted as RBC over 30/HPF and RBC dysmorphism 90%. On the immunofluoroscent microscope of renal biopsy, IgA deposit on mesangial matrix was noted.
