We reviewed 45 cases of ovarian tumors treated at Seoul National University Children's Hospital from 1983 to 1993. Forty-five patients were operated upon for 52 ovarian tumors. The most common pathologic diagnosis was mature teratoma. The next were functional cyst, the tumors of epithelial cell origin, and those of stromal origin in order of frequency. Six patients(13%) had malignant tumor. There were one malignant teratoma, two dysgerminomas, one endodermal sinus tumor, and two granulosa cell tumors. Four cases were diagnosed as torsion of ovarian cyst preoperatively, and emergency exploratory laparotomy were performed. There were three cases of ovarian tumors associated with precocious puberty. The most widely used diagnostic tool was ultrasonography. In the treatment of these 45 patients, unilateral oophorectomy was done in 38 cases, unilateral oophorectomy with wedge resection of contralateral ovary was done in 5 cases, unilateral oophorectomy with contralateral simple cystectomy was done in one case and total abdominal hysterectomy with bilateral salpingooophorectomy was done in one case. Of the six cases of malignancy, five patients are alive 2 to 6 years after operation and one case was lost to be followed up.

Objectives: The purpose of this study is to report the effects of herbal medicine on corpus luteum and luteal hemorrhage. Ovulation is a physical event and hemorrhage from corpus luteum is known to occur in reproductive age group women. Life threatening hemorrhage requires surgical intervention and blood transfusion. Methods: The patients of this study are 34-year-old and 16-year-old females. They were diagnosed as the hemorrhagic corpus luteal cyst. Two patients was advised to be operated beacause of rupture possibility. They were treated by traditional Korean Medicine, herbal medicine (Bokryungdosu-tang), acupuncture and moxibustion. Results: After the treatment, the patients recovered their condition. One patient was diagnosed with disappearance of existing corpus luteum, the other was relieved of heavy abdominal pain, vaginal discharge and lumbago. Conclusions: Thess cases show that traditional Korean treatment might be effective on corpus luteum and luteal hemorrhage.

Eighteen multiparous and 8 nulliparous cows with cystic ovarian disease (19 having follicular cysts, 7 with luteal cysts) were administered either 3000 I. U. HCG or $300{\mu}g$ LHRH. Ten animals responded satisfactorily leading to normal estrus within a period of 15 to 30 days and subsequent conception. In 8 animals cysts recurred and no effect of treatment was observed in 3 patients. Plasma progesterone concentration was significantly lower in animals having follicular cysts compared to those with luteal cysts.

Objectives: The purpose of this study is to review the clinical research trends of ovarian cysts and to recognize the efficacy of Korean medicine intervention. Methods: Based on four domestic databases, including Korean studies Information Service System (KISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Korean Medical Database (KMbase) and Research Information Sharing Service (RISS), we analyzed the case reports using Korean medicine intervention, which include acupuncture, moxibustion and herbal medicine. Data retrieval was carried out from May 12^th, to 18^th, 2022, and a total of 9 papers were included. Results: All papers were published in Korea and they contain seventeen case reports in total. The most frequently used intervention was herbal medicine, especially Gyejibokryeong-hwan-gami (桂枝茯苓丸加味), Guichulpajing-tang-gagam (歸朮破癥湯加減), Guibiondam-tang-gami (歸脾溫膽湯加味). Most cases reported statistically significant results on using Korean-medicine intervention. Also, there was no serious side effect of Korean medicine. Conclusions: In this study, we investigated the efficacy of Korean medicine intervention as an adjuvant therapy for ovarian cyst patients and research trends on ovarian cysts. Further studies are needed to supplement the safety and the evaluation of Korean medicine. However, the results should be taken cautiously as more clinical studies are needed.

microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by targeting the 3'-untranslated region of multiple target genes. Pathogenesis results from defects in several gene sets; therefore, disease progression could be prevented using miRNAs targeting multiple genes. Moreover, recent studies suggest that miRNAs reflect the stage of the specific disease, such as carcinogenesis. Cystic diseases, including polycystic kidney disease, polycystic liver disease, pancreatic cystic disease, and ovarian cystic disease, have common processes of cyst formation in the specific organ. Specifically, epithelial cells initiate abnormal cell proliferation and apoptosis as a result of alterations to key genes. Cysts are caused by fluid accumulation in the lumen. However, the molecular mechanisms underlying cyst formation and progression remain unclear. This review aims to introduce the key miRNAs related to cyst formation, and we suggest that miRNAs could be useful biomarkers and potential therapeutic targets in several cystic diseases.

Successful induction of lactation in 5 nulliparous repeat breeding cows was achieved by administering diethyl stillboestrol (0.1 mg/kg B.W.) and hydroxyprogesterone caproate (0.25 mg/kg B.W.) for 3 days followed by reserpine (4 mg/day) for 4 days, and dexamethasone (16 mg/day) for one day. The treatment caused cystic ovarian condition in all the animals. Intravaginally progesteronesoaked sponges suppressed but did not eliminate the behavioural estrus. Administration of LHRH ($300{\mu}g$) regressed the cysts in all animals in the first instance but the cysts reappeared in 2 animals. One animal became pregnant and delivered a normal calf.

Diagnosis on reproductive failures of dairy cows by ultrasonography was performed for 151 dairy cows. To diagnose types of reproductive failures, ultrasonography (SA 600, Medison, 5.0 MHz rectal linear transducer) was carried out in combination with rectal examination. Of 151 dairy cows, pregnant cows were 13 and the cows in normal estrual cycle were 40 cows, thereby the cows with reproductive failures were 98 cows. 1. Of 98 cows with reproductive failures, the cows with ovarian diseases were 34 cows (34.7%) and the cows with uterine diseases were 41 cows (41.8%). 2. The diameter of follicle in proestrus was 1.94 cm and it was longer than that of follicle in diestrus (p<0.05). 3. The mean size of corpus luteum of pregnant cows was bigger than that of corpus luteum in normal diestrus (p<0.05). 4. The length of cystic corpus luteum was 3.26 and the width of that was 1.91 cm. The length of corpus luteum tissue was 1.95 and the width of that was 1.91 cm excluding the size of cavity in corpus luteum. 5. The mean length of follicular cyst was 3.31 and the mean width of that was 2.3 cm. 6. The mean length and width of luteal cyst was 3.45 and 2.25 cm, respectively. The mean length and width of corpus luteum tissue was 1.15 and 0.67 cm, respectively, excluding the size of cyst in the luteal cyst. 7. The width of uterine horn associated with endometritis was significantly reduced as the period after parturition was elapsed (p<0.05). The mean width of uterine horn within 40 days after parturition was 4.55 cm. These results indicated that ultrasonography is of great use for accurate diagnosis both on ovarian diseases and uterine diseases and that it is very effective to diagnose endometritis in dairy cows.

This study was carried out to monitor the response of ovaries and cyst according to treatment with GnRH or combination of GnRH and $PGF_2{\alpha}$ in dairy cows with ovarian follicular cysts. Thirty cows were diagnosed as having follicular cysts by rectal palpation, ultrasonography and progesterone (P4) assays. Ten cows were treated with GnRH (control), and the other twenty were treated with $PGF_2{\alpha}$ at 10 days after GnRH treatment. All the animals were re-examined by ultrasonography and blood was collected for the measurement of plasma P4 concentration at day 0 (the day of treatment), day 7, day 10, day 13, day 24 and day 34, respectively. In 30 cows that were diagnosed with follicular cysts, mean plasma P 4 concentrations on day -II and day -I were 0.3 ng/ml and 0.4 ng/ml. On day 10 increased as 2.7$\pm$0.2 ng/ml. Mean cystic wall thickness by ultrasonography on day -11 and day -I were 2.1 mm and 2.2 mm. In 9 cows responded on luteinization of cystic wall, cystic wall thickness was 3.9$\pm$0.5 mm at day 10 after GnRH treatment. The responses of ovaries until day 10 after GnRH treatment included development of corpus luteum in the ovary bearing the cyst or in the contralateral ovary (12 cows), luteinization of cystic wall (6 cows) and clouding of the anechoic antrum of cysts (2 cows). The ovarian responses according to the combination of GnRH and $PGF_2{\alpha}$ included regression of the corpus luteum (12 cows), increase (1 cow) and no change (1 cow) of cyst size until last examination, and complete disappearance on day 13 (6 cows), 23 (6 cows) and 34 (4 cows). Combination treatment group of GnRH and $PGF_2{\alpha}$ showed a higher pregnancy rate within 100 days after initial treatment (40.0 vs 65.0%) and shorter intervals from the treatment to conception (45.4$\pm$25.8 vs 53.5$\pm$31.4 days) compared with control. It was concluded that the administration of $PGF_2{\alpha}$ following GnRH treatment is effective in shortening the interval from treatment to conception in cows with follicular cyst. Also, this study suggested that the response of the cyst according to treatment revealed various types. Therefore, veterinarians should pay attention to monitor of the response of cystic ovaries after treatment, specially no change, slowly decrease or increasement of cyst size after treatment.

Histological investigation of the number of follicles following gonadotropin treatments for superovulation was carried out in mature Sprague-Dwaley(SD) rats. Routinely serial sections of paraffin-embedded ovaries were stained with hematoxylin-eosin and evaluated with light microscope. During the study unusual cases of microscopic alterations were observed in the medulla of ovaries in two rats. Case one: An ovum and its follicular fluid outflowed in medulla of ovary. The follicular fluid was densly proteinuous. Corona raiata consisted of 2-6 layers thick cells in the periphery of the ovum. While the cortical side of the follicular wall was intact with normal granulosa cell layer the meullary side of it was ruptured. Case two: A large cyst was present in medulla of ovary hilus. The cyst occupied the entire medulla displacing the ovarian archetecture and enclosed by connective tissue and smooth muscle wall.

The objective of this study is to investigate the changes in concentrations of blood urea nitrogen (BUN) and sex steroid hormones, such as estrogen, progesterone, and testosterone in Korean cattle (Hanwoo) with reproductive disorders and to examine the relationship between BUN and body condition score (BCS) in Hanwoo. The concentration of BUN was 16.2 mg/dl, 17.8 mg/dl, 15.1 mg/dl, 17.9 mg/dl, and 28.3mg/dl in pregnancy, repeat breeding, follicular cyst, luteal cyst, and ovarian atrophy, respectively. In Hanwoo with BCS $2.0{\sim}2.9$, $3.0{\sim}3.5$ and $3.6{\sim}4.0$, the concentration of BUN was 15.8 mg/dl, 17.0 mg/dl, and 17.6 mg/dl, respectively. Fluoroimmunoassay showed that serum estrogen and progesterone levels were decreased in reproductive disorders Hanwoo, such as ovarian atrophy, endometritis, and weak estrus. The testosterone level was significantly decreased in Hanwoo with reproductive disorders compared to that in pregnant Hanwoo ($0.02{\sim}0.03\;ng/ml$ vs 0.13 ng/ml, p<0.05). The progesterone and estrogen concentrations in follicular fluid obtained from ovary with follicular cyst were significantly higher (p<0.05) than those in normal follicle fluid. These results show that there is no relationship between BUN and BCS in Hanwoo, and the concentration of sex steroid hormone in serum and follicular fluid are changed in reproductive disorders Hanwoo.
