This study was conducted to evaluate the clinical relevance and effectiveness of ovariectomy (OVE) and ovariohysterectomy (OVH) in terms of postoperative pain behavior and surgical stress. Thirteen healthy intact mongrel purpose-bred female dogs were used in this study. OVE was performed in six dogs whereas OVH was performed in seven dogs. Prior to, 1, 2, 4, 6, 12, and 24 h after surgery, pain assessment was performed by using the Short form of Composite Measure Pain Scale (CMPS-SF) and blood analysis for the determination of glucose, creatine kinase (CK), and cortisol were done. Also, surgical time, duration of anesthesia, and incision length were compared between two groups. As a result, OVH group as opposed to OVE group showed significantly longer in surgical time, duration of anesthesia, and incision length. Also, based on the two-way ANOVA test, the CMPS-SF had significant differences (p < 0.05) between two groups, with the OVE dogs having lower values at 1, 2, 4, and 6 h postoperatively. In addition, in terms of CK, the value at 1, 2, 4, 6, and 12 h were significantly (p < 0.05) increased from the baseline value for the OVH group. However, as for CK in OVE group, the values at 4, 6, and 12 h were significantly increased from the baseline value. As for blood glucose, a significant (p < 0.05) increase from the baseline was shown at 1 h postoperatively in OVH group and no significant increase was shown in OVE group. In terms of serum cortisol level, the values at the 1 and 2 h were significantly (p < 0.05) increased from the baseline value for both groups. In conclusion, our study has shown that OVE can be considered as a superior choice in terms of sterilization technique in female dogs, considering shorter incision length, surgical time, duration of anesthesia along with lower pain and surgical stress response than OVH.

Laparoscopic-assisted ovariohysterectomy was performed in a cat (2.7 kg) with pyometra. A 10-mm operative laparoscope was inserted into the abdomen through an umbilical port. A transabdominal suspension suture was placed to maintain the exposure of the ovarian vascular pedicle. The ovarian vascular pedicle and suspensory ligament were progressively cauterized and transected with 5-mm multifunction bipolar grasping forceps. Both ovaries and the uterus were exteriorized via 5-mm caudal port enlarged to 2 cm. The uterine body and associated arteries were ligated, transfixed, and transected under direct vision. No peri- or post-operative complications were encountered. To the authors' knowledge, this is the first report of the use of laparoscopy for the treatment of pyometra in the cat.

개에서 정상 발정주기 때와 자궁 축농증에 이환 되었을 경우 이에 대한 전침 자극의 효과를 알아보기 위하여 본 실험을 실시하였다. 정상 자궁 운동은 발정기 때에 최대이었으며 발정정지기 때에 운동성이 감소되거나 결여되었다. 발정정지기 때에 전침자윽을 하거나 Prostagrandin $F_2{\alpha}$를 투여하였을 경우에는 자궁의 운동성이 크게 증가하였다. 자궁경관이 열린 자궁축농증에 이환된 두 마리에서 전침자극을 3~4일간 실시하였다. 자궁의 직경은 감소되었고 질 분비물은 증가한 후 이후 감소하였다. 환축은 회복되는 경향을 보였으나 축주의 요구에 의하여 난소자궁절제술을 시행하였다. 본 실험의 결과를 통하여 전침자극은 자궁 축농증에 이환된 환축에서 축주가 번식용으로 계속 기르기를 원한다거나 또는 난소자궁절제술을 환축에 적용하는데 있어서 수술적인 위험이 높을 때에 적용 가능한 새로운 치료적 대안이 될 수 있음을 알 수 있었다.

흰쥐의 난소 절제로 야기된 골손실에 미치는 골쇄보의 영향을 관찰하였다. 난소 절제 후 흰쥐의 체중은 증가하고 자궁의 무게는 감소하였는데, 골쇄보는 특별한 영향을 주지 않았다. 그러나, 난소 절제 후 흰쥐의 tibia에서 측정한 골밀도는 대조군에 비하여 22% 감소되었으나, 골쇄보와 17be1a-estradiol를 투여한 경우는 골밀도의 감소가 현저히 억제되었다. 난소를 절제한 실험군에 골쇄보와 17be1a-estradiol를 투여하고 전자 현미경으로 관찰한 결과, trabecular bone의 미세분자 표면이 보호되는 것으로 관찰되었다. 이러한 결과들을 볼 때, 골쇄보가 17be1a-estradiol 만큼 난소 절제술 후 진행되는 골손실을 예방하는데 효과적임을 강하게 나타내고 있다고 사료된다.

A 1-year-old, 2.35 kg spayed female American short hair cat was referred with episodic signs of heat at 3 months after ovariohysterectomy. Through the screening tests, bilateral cystic, ovary like masses were shown at the caudal to both kidneys with high serum estradiol concentration. It was considered that the patient was suffered from ovarian remnant syndrome. Laparoscopic exploration was performed, and each of mass lesions was resected by ultrasonic scalpel. Patient was recovered favorably and has been doing well without recurrence of estrus signs until 2 years after surgery.

Objectives: The aim of this study was to assess the change of ovarian reserve after removal of ovarian tumor using basal FSH, $E_2$, clomiphene citrate challenge test and ovarian volume. Methods: Twenty two patients with unilateral ovarian tumor, ${\leq}35$ years old, regular menstrual cycle were collected prospectively and divided into endometrioma or non-endometrioma group. We measured the ovarian volume with transvaginal ultrasonography on the day 3 of menstrual cycle within one month before and 3 months after surgery. Basal (cycle day 3) FSH, $E_2$ and CCCT were checked before surgery and repeated at least 2 spontaneous cycles later after surgery. Three patients that had been pregnant within 3 months after surgery were excluded in analysis. Results: The ovarian volume was reduced significantly after surgery in endometrioma and non-endometrioma ${\geq}10\;cm$ group ($4.79{\pm}2.57\;cm^3$ and $5.21{\pm}1.33\;cm^3$, respectively), but not in the non-endometrioma <10 cm group ($6.18{\pm}2.85\;cm^3$). After surgery, basal FSH and cycle day 10 FSH on CCCT in endometrioma and non-endometrioma were $4.25{\pm}0.20\;mIU/ml$ and $3.79{\pm}0.80\;mIU/ml$, $4.24{\pm}0.85\;mIU/ml$ and $4.28{\pm}0.92\;mIU/ml$, respectively. There were neither significant difference in comparison with the preoperative results nor between two groups. Conclusions: Enucleation of ovarian mass was associated with a significant reduction in ovarian volume in endometrioma and non-endometrioma larger than 10cm in diameter. Hormonal markers for evaluation of ovarian reserve, such as basal and cycle day 10 FSH on CCCT, were not changed significantly in each group. In reproductive age women, conservative enucleation or cystectomy rather than oophorectomy should be considered even in a large benign tumor and ovarian function could be reserved by meticulous operative technique.

Menopause is often associated with the incidence of several chronic diseases including osteoporosis, cardiovascular disease, and obesity. Hormone replacement therapy (HRT) is an effective regimen that has been found to prevent these diseases in postmenopausal women. However, HRT is accompanied by an increased risk of unfavorable outcomes. Therefore, this study was conducted to evaluate the effects of Ecklonia cava, a kind of seaweed, extract on bone turnover markers in symptomatic menopausal women. For this study, the following four groups of 9-week-old Sprague-Dawley rats were evaluated over 6 weeks: normal rats (SHAM), ovariectomized rats (OVX-CON) and ovariectomized rats that were treated with Ecklonia cava extracts. The optimum extraction temperature and solvent of Ecklonia cava were found to be $80^{\circ}C$ and 80% ethanol. We measured the osteocalcin and CTx content, enzyme ALP activity in serum and collagen content in the cartilage, bone, skin and lungs. We found that the levels of indicators of bone metabolism such as ALP, osteocalcin and CTx were lower in rats in the Ecklonia cava extract group than the OVX-CON group. In addition, the collagen contents in the bone, cartilage, skin and lungs decreased in response to ovariectomy, but the levels of collagen were greater in the bone of rats that were treated with Ecklonia cava extract than in the bone of rats in the OVX-CON group. According to these results, we were able to know the effects of Ecklonia cava extract on bone aging in ovariectomized rats. Consequently, we expect Ecklonia cava extract to have an effect on bone aging in postmenopausal women.

The objective of this study was to compare the total surgical time, pain score and hemorrhage after ovariohysterectomy (OVH) and bilateral flank ovariectomy (BFOVE) with hemoclips in dogs. OVH was operated on six dogs and BFOVE was performed on six dogs. In BFOVE group, both ovarian pedicle hemostasis applied using hemoclips after removing ovaries. Total surgical time was recorded from starting incision of skin to closure last skin suture. Pain score was measured at 2, 6, 12, and 24 hours after surgery based on University of Melbourne Pain Scale (UMPS). Hemorrhage around clipping area, uterus, abdominal muscles, and skin were monitored after surgery. BFOVE technique could reduce total surgical time and pain after surgery. There was no hemorrhagic problems near ovarian pedicles following surgery. BFOVE with hemoclips could be useful and recommended for sterilization in dog.

Alopecia was the main complaint in a 4 year old female Cocker spaniel dog. bilateral alopecia has been presented on skin lesion for 10 months after ovariohysterectomy about one year ago. Hyperestrogenism was diagnosed by the blood estradiol level test. Left ovarian cyst was resected in the intact ovarian position by laparotomy. Total size of the cyst was about 3 cm and it was the shape of follicular cyst. Blood estradiol level is usually higher than normal in ovarian cyst. But even though estradiol level is in normal range, dermatitis could be induced because the number of estrogen receptor of the skin would be increased or the duration of estrogen secretion would be prolonged. Because the hyperestrogenism in this case is iatrogenic, exact and proper ovariohysterectomy should be made not to induce the complications.

연구 목적: 난소에서 분비되는 스테로이드 호르몬인 에스트로젠과 프로게스테론은 포유동물의 생식기관 발달과 정상적인 생식 기능, 수정과 배아의 착상에 중요한 역할을 한다. 특히 에스트로젠은 자궁내액을 내강으로 분비하여 자궁부종 기작에 중요한 역할을 한다. 자궁내액은 정자의 수정능력 획득과 착상전 배아의 발달에 매우 중요하다. Aquaporin (AQP)은 막관통 물수송 단백질로서 여러 조직에 넓게 분포되어 있으며, 세포간 또는 상피세포간 물의 이동에 중요한 역할을 한다. 본 연구에서는 생쥐 자궁에서 스테로이드 호르몬에 의해 조절되는 자궁내액의 이동에 AQP 유전자가 관여하는지를 알아보았다. 연구 재료 및 방법: 난소 절제술을 시행한 생쥐에 스테로이드 호르몬을 피하주사하고 6, 12, 24시간 간격으로 자궁조직을 적출하였다. 대조군은 sesame oil만을 주사한 후 6시간째에 수획한 자궁조직을 사용하였으며, 실험군은 시간대별과 스테로이드 처리별로 채취한 자궁조직에서 역전사중합효소반응을 수행하였다. 역전사중합효소반응을 통해 막관통 단백질인 AQP-4, -5, -8 mRNA의 발현양상을 살펴보았다. 또한 mRNA의 위치를 살펴보기 위해 laser microdissection을 이용하여 RT-PCR을 수행하였다. 마지막으로 자궁조직내에서의 단백질 발현 부위를 관찰하기 위해 면역조직화학염색을 실시하였다. 결 과: AQP-4, -5, -8 mRNA은 프로게스테론을 처리한 군보다 에스트로젠을 처리한 군에서 많이 발현되었으며, 에스트로젠을 주사한 지 6시간째 발현정도를 대조군과 비교할 때 AQP-4, -5, -8 mRNA가 각각 7.9배, 2.8배, 3.8배로 나타났다. AQP-4, -5, -8 mRNA는 간충조직보다 자궁내 상피조직에서 스테로이드 호르몬의 영향을 받아 발현양상의 차이가 나타났으며, 주로 에스트로젠의 영향을 받아 발현이 증가하였다. AQP-4 단백질은 에스트로젠을 24시간 처리한 후 프로게스테론을 처리한 군의 자궁내 상피조직에서 많이 발현되었으며, AQP-5와 -8 단백질은 에스트로젠을 처리한 군의 자궁내 상피조직에서 발현이 증가하였다. 결 론: 이상의 결과를 통해 AQP-4, -5, -8은 주로 에스트로젠에 의해 자궁내 상피세포에서 발현이 증가되는 것으로 보아 에스트로젠의 영향하에 일어나는 자궁내액의 이동으로 인한 자궁부종기작에 이동통로로서 관여하는 것으로 사료된다.
