Aggressive angiomyxomas (AAMs) are rare, benign, but locally aggressive, hypocellular soft tissue neoplasms found in the vulvovaginal region. AAMs are most commonly found in women in their reproductive years. Only about 150 cases of this rare, soft tissue tumor have been reported thus far, most of which are reported from the gynecologic, obstetric, urologic, and pathologic fields. AAMs are considered to be a slow-growing mesenchymal tumor with a locally infiltrative growth pattern. There are only two reports of metastasic disease. We have managed a case of AAM which occurred during adolescence and was pathologically-confirmed.

Lipomatous tumors are the most common mesenchymal tumor. But, pure lipoma of the uterus is very rare and only few cases are reported in international literatures. These tumors usually develop in postmenopausal women and symptoms are similar to leiomyoma. We report a case of a pure uterine lipoma in 64-years-old woman presenting with palpable pelvic mass and voiding difficulty in which a preoperative diagnosis was made by magnetic resonance imaging (MRI), then pathologically confirmed after the operation.

OBJECTIVE: This study was designated to determine the effect of cord blood cell transplantation in ischemic injury model. METHODS: In this study, we administered human umbilical cord blood (hUCB)-derived CD34(+) cells into the lateral ventricle or directly into the striatum and assessed cell migration in mice with cryoinjury and behavioral recovery in rats with transient middle cerebral artery occlusion (MCAo). CD34(+) cells were isolated by magnetic cell sorting using CD34-microbeads and labeled with CM-Dil. RESULTS: When CD34(+) cells were injected into mice brain with cryoinjury, cells were migrated into a injury site after one week of injection. Similarly, injected CD34(+) cells were migrated into the periphery of infarcted area in rats with transient MCAo. When spontaneous activity was measured using a modified neurological severity score (mNSS), it was found that functional recovery was significantly higher when CD34(+) human umbilical cord blood cell (hUCBC) was transplanted 24 hours after stroke compared with phosphate buffered saline (PBS)-injected or CD34(-) transplanted, stroked animals (P<0.05). Although only small portion of transplanted cells were differentiated into neural lineages, CD34(+) hUCBC transplantation increased Brdu incorporation and recruitment of doublecortin (DCX) (+) cells in ischemic boundary zone. CONCLUSION: These results suggest that hUCBC transplantation may be an effective treatment for brain injuries, such as stroke, or neurodegenerative disorders by promoting endogenous repair process of the brain.

Cushing's syndrome in pregnant women is rare and difficult to be diagnosed because of the syndrome's association with oligomenorrhea or amenorrhea and the changes in cortisol metabolism during normal pregnancy. Cushing syndrome in pregnancy is usually confused with complicated pregnancy, such as preeclampsia or gestational diabetes, and its rarity leads to a low degree of clinical suspicion, often delaying diagnosis. We experienced a case of Cushing's syndrome in pregnancy, which had been considered as the severe preeclampsia and gestational diabetes due to uncontrolled hypertension and hyperglycemia. The pregnancy was terminated with an emergency cesarean operation at 30 weeks of gestation because of severe preeclampsia. In consequence of the evaluation about the Cushing's syndrome after delivery, the adrenal cortical adenoma of right adrenal gland was diagnosed and laparoscopic adrenalectomy was performed.

OBJECTIVE: To investigate the effects of leptin on in vitro development of mouse embryos. METHODS: Female C57BL mice, aged 8 to 15 weeks, were superovulated with IP injection of 5 IU of PMSG followed by 5 IU hCG at 48 hours later. And then the mice were mated with male mice. The next morning, one-cell embryos were collected and cultured in media added with various concentrations (0, 5, 50, 500 ng/mL) of leptin for 4 days. In addition, to determine whether the sensitivity to leptin varied at different stages of development, embryos at 2- or 4-cell stage were treated with the same concentrations of leptin and cultured up to blastocyst stage. The total cell number of blastocyst was assessed and the expression of leptin receptor was examined in all stages of development by immnuofluorescence. RESULTS: The rate of blastocyst formation from one-cell embryos significantly increased at culture media that leptin was added at 50 ng/mL concentration, whereas decreased at 500 ng/mL concentration compared to the control (P<0.05). The development rate of embryos, from 2-cell stage, was similar to the rate from 1-cell stage. However, the addition of leptin to culture media in 4-cell embryos had no significant effects on embryo development compared to the control. In addition, the dose-dependent stimulatory or inhibitory effect of leptin on embryo development was weakened at 2-cell and 4-cell embryo stages compared one-cell embryo stage. The total cell number of blastocyst also significantly increased at 50 ng/mL of leptin, but decreased at 500 ng/mL. Leptin receptor was expressed in all stages from one-cell embryos to blastocyst. The intensity of Ob-Rb immnuostaining was mainly stronger in one- or two-cell embryos, decreased with advancing development stages, and increased again in blastocyst. CONCLUSION: This study shows that addition of leptin to embryo culture media affects embryo development in a dose-dependent and developmental stage-dependent manner. The effects of leptin seems to be associated with the expression pattern of leptin receptor at different stages of development.

OBJECTIVES: We examined the effect of sildenafil citrate on advanced glycation end products (AGEs)-induced soluble fms-like tyrosine kinase 1 (sFlt-1) release in JEG-3 choriocarcinoma cells. METHODS: Cells were incubated with control bovine serum albumin (BSA) or AGEs-BSA, and expression of sFlt-1 mRNA and protein release was determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. AGEs-BSA increased sFlt-1 mRNA expression and protein release in a dose-dependent manner. RESULTS: Sildenafil citrate suppressed sFlt-1 mRNA expression and protein release in cells treated with AGEs-BSA in a dose-dependent manner. Likewise, it inhibited the increase of reactive oxygen species (ROS) production and NF-kappaB activity in these cells. Cobalt protoporphyrin (CoPP) and bilirubin also inhibited sFlt-1 release and ROS production in cells treated with AGEs-BSA, whereas zinc protoporphyrin IX (ZnPP IX) antagonized the effect of sildenafil citrate. In cells transfected with the heme oxygenase-1 (HO-1) siRNA, sildenafil citrate failed to inhibit the sFlt-1 release and ROS production. CONCLUSION: These results strongly suggest that sildenafil citrate inhibits sFlt-1 release and ROS production in cells treated with AGEs-BSA through upregulation of the HO-1 expression in JEG-3 cells.
