  • An 11-year-old intact female miniature poodle presented with a four-month history of hemorrhagic effusion. The patient was alert on physical examination, although muffled heart sounds were noted upon auscultation of the right hemithorax. The radiographic finding was pleural effusion. Ultrasonography revealed cystic changes in both ovaries and several nodules in the liver. A refractory opacity in the right lung field, as visualized with computer tomography (CT), was diagnosed as right middle lung lobe torsion with a collapsed bronchus. Five days after diagnosis, a right fifth intercostal thoracotomy was performed to remove the right middle lung lobe; the right middle lung lobe was grossly shrunken as a result of chronic lung lobe torsion. Ovariohysterectomy was also performed. Histopathologic examination revealed papillary adenocarcinoma in both ovaries and suspected metastasized ovarian adenocarcinoma cells in the lung lobe. The patient recovered favorably and had been doing well up to two months post-surgery. However, after four months, the dog presented with respiratory difficulty. The radiographic findings were pleural effusion and collapse of the right cranial and left caudal lung lobes. Malignant cells of epithelial origin were observed in the pleural effusion. The tumor cells were suspected to be metastasized cells from the previously resected lung lobe. Although cancer treatment was recommended, the suggestion was suspended and the dog was discharged from hospital. This was a case of lung lobe torsion that had occurred because of hemorrhagic effusion due to tumor. Although ovariohysterectomy and lobectomy were performed, there was a relapse of hemorrhagic effusion because of metastasized tumor from the previously resected lung lobe.

  • A 12-year-old, intact female Yorkshire terrier was presented with progressive abdominal distention. On radiographic and ultrasonographic evaluation, a large mass was detected in right upper abdomen and it had several discrete anechoic follicles and large cysts. The mass was removed by complete ovariohysterectomy and the resected specimen was histopathologically examined. Based on the gross and histopathologic findings, the mass was definitely diagnosed as malignant granulosa cell tumor (GCT). Until now, the dog has been successfully managed more than a year without complications.

  • Objectives: The purpose of this study is to examine the effects of Sagunjatang-Gami(SGJT) on uterine and ovarian function in the ovariectomized rat postmenopause model. Methods: SGJT was administered in ovariectomized Wister albino female rats for three month. After that, uterine weight, uterine index, serum estradiol-$17{\beta}$ levels and phosphorylation of ERK or AKT, and histological analysis of uterus were measured to assess the impact on uterine and ovarian function in ovariectomized rats. In addition, phosphorylation of $ER{\alpha}$, ERK, AKT by SGJT in MDA-MB-231 cells were measured. To identify safety of SGJT, the cell cytoxicity in MDA-MB-231 cells and serum GOT, GPT levels were measured in ovariectomized rats. Results: The results were as follows. 1. SGJT decreased the viability of MDA-MB-231 cells in a dose-dependent manner. 2. The level of serum GOT, GPT in SGJT-treated group showed significant decrease in comparison with control group. 3. Phosphorylation of $ER{\alpha}$, ERK, AKT by SGJT in MDA-MB-231 cells were increased. 4. Uterus index in SGJT-treated group showed significant increase in comparison with control group. The level of serum estradiol-$17{\beta}$ in SGJT-treated group showed significant increase in comparison with control group. Phosphorylation of ERK or AKT by SGJT in the uterus of ovariectomized rats was increased significantly. 5. Uterus index and the level of serum estradiol-$17{\beta}$ in SGJT-treated group increased at higher rates in comparison with estrogen-treated group. Conclusions: Taken together, we suggest that SGJT has been shown to be effective in preventing postmenopausal uterine and ovarian degeneration and curing postmenopausal low estrogen related symptoms.

  • Most elderly women experience a decrease in their bone density due to a deficiency of calcium intake, ovariectomy, or menopause. This study evaluated the usability of the microscrew as a skeletal anchorage system in these orthodontic treatment cases, using rats as a research group. The 4 month old sprague-dawley species rats were divided into two groups, the OS (Ovariectomy Screw), and the SS (Sham operation Screw) group. In both the OS and SS groups, microscrews were implanted into the palatal bone between the upper molar teeth and two upper incisors were retracted using NETE coil spring with 75 g of force. After 3days, the again after 7 days, 7 rats in each group were sacrificed. Three days before they were sacrificed, Alizarin red S was intraperitoneally injected, and their maxillary bone, tibia and blood from their hearts were taken. The components of the extracted blood were biochemically analyzed and non-decalcified grinding resin sections for maxillary bone and tibia were made. The sections were examined with a polarization microscope, and fluorescent microscope. Smaller concentrations of Ca and P, the inorganic substances closely related to bone density, were found in the extracted blood of the OS group. Both OS and SS groups showed a possibility of bone remodeling with a high concentration of ALP after 7 days. An increase in bone density on the tension and compression sides of the microscrew and the tension side of the tooth for both OS and SS groups was confirmed with a polarization microscope. However, the bone density of the pressure side of the tooth and apical side was decreased. More deposits of Alizarin red S in the bone after 7 days rather than 3 days seen with a fluorescent microscope suggested the existence of new bone formation.

  • To prevent and treat the osteoporosis, diverse therapies have been applied, which is still need to solve negative side effects. We investigated the effects of the extract from alternative medicine(AM) on the progress of bone loss in ovariectomized-rats fed with Ca-deficient diet for 7 or 14 weeks. Ovariectomy(OVX) concomitant with Ca-deficiency caused bone loss evidently decreased in bone mineral density and bone strength of femoral epiphysis and vertebrae, which were ameliorated with administration of AM extract. Also, the effect of AM extract on the biochemical markers were measured. The increased serum alkaline phosphatase caused by OVX and Ca-deficiency were observed, which were not affected by administration of AM extract. Administration of AM extract may have preventive effect on the elevated serum acid phosphatase concentrations caused by OVX and Ca-deficiency at 14 wks, implicating that AM extract possibly acts toward reducing born resorption, even though the results were not statistically significant. Serum osteocalcin and urinary deoxypyridinoline, the markers of bone turn over, were not changed by estrogen deficiency or AM extract. We concluded that the AM extract treatment had potently preventive effects on the decreased bone density and bone strength induced by OVX and Ca-deficiency. The changes of biochemical markers related to the effect of AM extract were not manifested but it still suggest that AM extract may inhibit the bone resorption derived from OVX and Ca-deficiency.

  • A 4-year-old female Shih-tzu dog weighing 5.1 kg was referred with abdominal distension and diagnosed as cystic papillary adenocarcinoma with metastasis to serosal surface of abdomen by biopsy. Intraperitoneal chemotherapy with cisplatin (50 $mg/m^2$) diluted in normal saline (250 $ml/m^2$) was initiated following removal of ascites one month after ovariohysterectomy (OHE). Clinical response was great and had no side effects during the chemotherapy period (3 relapses, 33 months after diagnosis). However, pleural effusion occurred with ascites and renal failure at the end of treatment. Eleven treatments of cisplatin were performed during 35 months after diagnosis. Intraperitoneal cisplatin instillation has been effective to control malignant ascites and pleural effusion in ovarian cancers and could be a reasonable palliative treatment. This is the first case report describing intraperitoneal cisplatin chemotherapy in metastatic ovarian cyst papillary adenocarcinoma in Korea.

  • Osteoporosis that is associated with ovarian hormone deficiency following menopause (postmenopausal osteoporosis) is by far the most common cause of age-related bone loss. Isoflavone has been reported as a natural substance that possibly minimizes bone loss in postmenopausal women. This study was conducted to investigate the preventing, treating effects of isoflavone on bone loss in ovariectomized rats. 120 Sprague Dawley rats of 13 week-old were devided into 2 groups, a treatment group and prevention group. Each group was consisted of six subgroups; control (CON), sham operated (SH) or ovariectomized (OVX) and isoflavone supplemented goups: OVX+0.25mg isoflavone/kg diet (OL), OVX+0.8mg isoflavone/kg diet(OM) and OVX+2.5mg isoflavone/kg diet(OH). to study the preventing effects of isoflavone on bone loss, OL, OM and OH groups were fed with isoflavone from 4 days after ovariectomization. Treating effects of isoflavone on bone metabolism were investigated with OL, OM, OH groups supplemented with isoflavone from 8 weeks after ovariectomization. Isoflavone supplementation continued for 8 weeks. At 8 weeks after ovariectomization significant increase in alkaline phosphatase occurred comparing with CON and SH group. By isoflavone supplementation from 4 days after ovariectomy alkaline phosphatase and urinary hydroxyproline were lowered and bone mineral density, bone strength of the femur and tibia and bone dry weight were slightly enhanced with no significant difference. Isoflavone supplemented group at the level of 0.8mg/kg diet (OM group) had significantly lower serum alkaline phosphatase, urinary hydroxyproline, and higher strength of femur than OVX group. Groups with isoflavone supplementation fro 8 weeks after ovariectomy had lower level of serum alkaline phosphatase, urinary hydroxyproline than OVX group. Bone mineral density, bone dry weight and bone strength of the femur and tibia were slightly enhanced by isoflavone supplementation. However there was no significanct difference between OVS ad isoflavone supplementation groups. The results suggest that isoflavone might have potential role for preventing postmenopausal bone loss. Isoflavone supplementation at early stage of postemenopause may be beneficial to age-related bone health.

  • This report aimed at investigating the differential gene expressions of the adhesion receptors between ovariectomized (OVX) and estrus stage rat uteri (OVX vs. estrus pair) using the cDNA expression away analysis. In addition, this report aimed at confirming of the differential gene expressions of the adhesion receptors between OVX and progesterone (P$_4$) injected OVX rat uteri (OVX vs. OVX+P$_4$ pair). RNA samples were extracted from the uterus and reverse-transcribed in the presence of [$\alpha$$^{32}$ P]-dATP. Membrane sets of Rat Atlas array 1.2 II (Clontech) were hybridized with CDNA probe sets. RT-PCR was employed to validate the relative gene expression patterns obtained by the cDNA array. The results were well consistent to cDNA array analysis data except the fold changes of gene expression. Among a total of 1176 cDNAs, 5 genes of adhesion receotor including embigin protein, activated leukocyte cell adhesion molecule, afadin, neuroligin 2, semaphorin Z showed significant (more than 2-fold) changes in the OVX vs. late estrus pair. All of these genes were up regulated in estrus stage than OVX rat uterus. In the OVX vs. OVX+P$_4$ pair, 4 genes including osteonectin, afadin, neuroligin 2, semaphorin Z showed significant changes. All of these genes were also up regulated in OVX+P$_4$ injected rat uterus than OVX control. Three genes including afadin, neuroligin 2, semaphorin Z which were up regulated in estrus and OVX+P$_4$ injected rat uteri of both experimental pairs than OVX rat uteri. These genes seem to be under the control of P$_4$.
