This study was carried out to monitor the response of ovaries and cyst according to treatment with dinoprost or fenprostalene in dairy cows with ovarian luteal cyst. Twenty cows were diagnosed as luteal cysts by rectal palpation, ultrasonography and progesterone analysis. The cystic cows were treated with dinoprost or fenprostalene. All the animals were re-examined by ultrasonography and blood was collected for the measurement of plasma progesterone concentration at day 0 (the day of treatment), 3, 13 and 24, respectively. Mean plasma progesterone concentrations on day -11 and day -1 before treatment were 2.1$\pm$0.2 ng/ml and 2.8$\pm$0.3 ng/ml, respectively. On day 3 and day 13 were 0.3$\pm$0.1 ng/ml and 4.3$\pm$0.2 ng/ml, respectively. Mean cystic wall thickness on day -11 and day -1 were 3.2$\pm$0.2 mm and 3.9$\pm$0.2 mm, respectively. And on day 3 was 2.4$\pm$0.3 mm. The responses of luteal cyst after treatment noted during ultrasonography included dramatical degeneration of the luteal tissue of cystic wall on day 3 (all cows), slowly reduction of cyst size (cyst resolution) until last examination (8 cows), complete disappearance on day 13 (7 cows) and no changes of cyst size (5 cows). A group of 10 cows with luteal cysts injected fenprostalene compared with another 10 cows treated dinoprost showed a slightly higher pregnancy rate on first service after initial treatment (50.0 vs 30.0%). But treatment effects of dinoprost or fenprostalene did not significantly different results for each groups. This study suggested that the response of the cyst according to treatment revealed various types. Therefore, veterinarians should have attention on monitoring of the response of cystic ovaries after treatment, specially on no change of cyst size after treatment.

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.

To establish the differential diagnosis and functional status in ovarian cystic cows, progesterone(P$_4$) and estrogen(E$_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian follicles were classified as systic if the diameter was greater than 25 mm by ultrasonography. Ovarian cysts < 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and >10 ng/ml E$_2$ concentration were classified follicular cyst, ovarian cysts 3 mm of cystic wall thickness, 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified luteal cyst, and ovarian cysts 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified non-functional ovarian cyst, respectively. Also ovarian cysts were classified 8 types by anatomical and hisctological findings. Ovarian cysts with corpus luteum were 3 of 73 cows and ovarian cysts without corpus luteum were 70 cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Aa 56.2%, 2Ba 20.5% and 2Ab 15.1%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 76.7% and luteal cyst 19.2%. The thickness of cystic wall were lAb 3.9 mm, 2Ab 3.3 mm and 2Bb 3.2 mm, and the cystic fluid P$_4$ concentrations were above 10.0 ng/ml in lAb, 2Ab and 2Bb, respectively. There was significantly correlations between the thickness of cystic wall and cystic fluid P$_4$ concentration in ovarian cysts(p<0.05). The ovarian cyst was classified follicular cysts, luteal cyst and non-functional ovarian cyst by hormone analysis. The luteal cyst was accuratly dignosed by cystic wall thickness. But follicular cysts was misdiagnosed 13 cows of 56 cystic cows. The 13 cystic cows was determined as had non-fuctional ovarian cysts. The cystic fluid P$_4$ concentration was 3.3 ng/ml in follicular ovarian cysts and 30.1 ng/ml luteinized ovarian cysts. There was significantly positive correlations between thickness of cystic wall and serum P$_4$ concentration in follicular(r$^2$ =0.59, p<0.001) and luteal cysts(r$^2$=0.65, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accuratly diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts was not diagnosed only cystic diameter and cystic wall thickness. In conclusion, it is suggest that ovarian cysts was diagnosed by combination of clinical sign and anatomical cystic features.

To investigate the changes of pituitary gland associated with ovarian cyst in Korean native cattle, pituitaries and ovaries were collected from 54 Korean native cattle at abbatoir. Pituitaries were stained with HerIant pituitary stain method and all the tissues were examined under light microscope. The results obtained were summarized as follows; 1. The delta cells and beta cells in the pars distalis were dull blue and violet in colors respeetively. Basophil size in the follicular phase and pregnant groups was larger than those of luteal phase and ovarian dysfunction groups. 2. The numbers of delta cells in the pars distalis of follicular cyst group were larger than those of remaining groups (p<0.01). 3. The distribution of delta cells in the acidophil zone was greater than that in the basophil zone of the follicular cyst and follicular phase groups. 4. The granulations of delta cells were more intensive in follicular cyst, follicular phase and pregnancy groups than in luteal phase and ovarian dysfunction groups (p<0.01). 5. The numbers of beta cells in follicular phase and ovarian dysfunction groups were larger than those in luteal phase and follicular cyst groups respectively (p<0.01). 6. In all groups, the distribution of beta cells was greater in basophilic zone than in acidophilic zone (p<0.01).

In 60 dairy cows with inactive ovaries, follicular cyst, luteal cyst, persistent corpus luteum and silent heat as diagnosed by rectal palpation, and those that had not resumed ovarian cycles until 60 days postpartum, progesterone concentrations for differential diagnosis of reproductive disorders were measured and were compared in matched plasma, skim milk and milk fat samples at 10 days interval. The incidence rate of reproductive disorders were as follows; inactive ovaries 20(33.3%), silent heat 11(18.3%), follicular cyst 7(11.7%), luteal cyst 7(11.7%), persistent corpus luteum 7(11.7%), pyometra 4(6.7%), vaginitis 2(3.3%), cystic corpus luteum 1(1.7%), and endometritis 1(1.7%), respectively. Cows having a progesterone concentration in plasma and skim milk < 1.0 ng/ml, and in milk fat < 80.0 ng/ml were considered to have inactive ovaries or follicular cyst. Those with concentrations in plasma and skim milk ${\geq}1.0ng/ml$, and in milk fat ${\geq}80.0ng/ml$ were regarded as the cases of luteal cyst or persistent corpus luteum. Progesterone concentrations in above cows did not differ significantly between the time of initial determination and the 10 days after initial determination. But progesterone concentrations in cows with silent heat did differ significantly between the time of initial determination and the 10 days after initial determination(P<0.05). The accuracy of rectal palpation for making a differential diagnosis of ovarian dysfunction, as defined on basis of progesterone concentrations, were as follows; follicular cyst 55.6%, luteal cyst 50.0%, inactive ovaries 90.5% and persistent corpus luteum 60.0%, respectively. It may be concluded that progesterone determinations at 10 days interval is practical as an aid to diagnosing ovarian dysfunction, particularly follicular cyst and luteal cyst.

Ultrasonographic diagnosis of genital disease and early pregnancy diagnosis was performed in Korean native cattle. The size of ovarian follicle in preovulation, luteal stage and follicular cyst was 18.9, 9.2 and 27.6 mm, respectively, and the thickness of follicular wall was 2.3, 1.8 and 2.8 mm, respectively. The size of corpus luteums in formation stage, activity stage, regression stage, cystic corpora lutea and luteal cyst was 6.2, 11.3, 8.6, 26.7 and 25.9 mm, respectively. The thickness of luteal wall in cystic corpora lutea and luteal cyst was 8.4 and 4.9 mm, respectively. The size of embryo or fetus on day 25, 27, 30, 35, 40, 45 and 50 was 0.8, 0.9, 1.3, 1.5, 2.2, 2.8 and 3.8 cm, respectively. The size of amniotic vesicle on day 25, 27 and 30 was 1.2, 2.1 and 3,0 cm, respectively. The diameter of pregnant uterus on day 25 and 27 was 7.0 and 7.8 cm, respectively. It was concluded that the ultrasonographci values determined in this study can be used as references for the treatment of genital disease and early pregnancy diagnosis in Korean native cattle.

Accuracy of rectal palpation and ultrasonography for differential diagnosis of subestrous dairy trows were investigatedl using the result of pIRsma progesterone assay. The ovaries were examined 2 times of 10 days interval in 520 posearom and postinsemination subestroHs dairy cows, using rectal palpation and B-mode transrectal ultrasonography. The results of rectal palpation, ultrasonographic examination and measurement of plasma progesterone profiles in 520 subestrous dairy cows were silent brat or error of estrus detection 303 (58.3%), persistent corpus luteum 59 (11.3%), follicular cyst 37 (7.1%), luteal cyst 16 (3.1%), inactive ovary 9 (1.7%), granulosa tumor 1 (0.2%), hydmsalphinx 1 (0.2%), endomehris 81 (15.6%), pyometra 12 (2.3%) and mummified fetus 1 (0.2%), respectively. Accuncy of rectal palpation and ultrasonography for diagiosing ovarian disordeir based on plasma progesterone profiles were silent heat or error of estrus detection 80.5% and 96.7%$\boxUl$ persistent corpus luteum 57.6% and 94.9%, follicular cyst 62.5% and 91.9%1 luteal cyst 62.5% and 87.5%, maclive ovary 55.6% and 88.9% and granulosa cell tumor 100% and 100%, respectively. Acnuucy of rectal palpation for diagnosing uterine disorders based on ultrasonography was pyometra 75.0%1 endometritis 51.9% and mummified fetus 100%, respectively. Cbaracteristic ultrasonographic appearances of ovaries in subestrous dairy cows were as follows; Silent heat or error of estrus detection: anechoic follicle or hypoechoic corpus luteum than ovarian stroma was alternately present on Day 0 (first examination) and Day 10. Follicular cyst: uniformly nonechogenic ovarian structure $\geq $ 25 mm in diameter with a wall < 3 mm was present in ipsilateral on Day 0 and Day 10. Luteal cyst: luteal cyst was similar to follicular cysts but thickness of cystic wall was $\geq $ 3 mm. Inactive ovary : structures within ovaries was not present on Day 0 Bnd Day 10. Characteristic uthssonograpsc appearances of uterus in subestrous dairy cows were as follows; Endometritis: characterized by uterine lumen containing fluid in which 'snowy'echogenic particles art suspended. Pyometra: ultrasonographic appearance of pyometra was diffuse echogenic particles distributed in fluid within the distended uterus, and a thickened uterine wall. These results indicated that ultrasonography was practical far diagnosing reproductive disorders. To diagnosing ovarian disorders, ultrasonography should be carried out 2 times of 10 days interval and rndometritis should be differentiated with uterus of luteal phase in normal cycling cows.

A total 5,946 cows from 24 dairy farms were carried out for the improvement of reproductive performance. Dairy cows in post-parturition 30 day were performed periodic reproductive examination to check for recovery of post-parturition ovary and uterus and for the early diagnosis of reproductive disease. The results obtained from this studies were as follow. The result of 1,126 cows with ovario-uterine disease were 579 slient heat and error of estrus detection (51.4%), 296 ovarian disease (26.3%), 248 uterine disease (22%), mummification and freematin were each 1 head (0.1%), respectively. Hormonal therapeutic effects were follicular cyst 81.5%, luteal cyst 90.7%, endometritis 86.9%, mucometra 90.1%, pyometra 60.9%, respectively. In cows, even if the 1st treatment fails, 2nd, 3rd treatment were performed. Therapeutic effect of 2nd, 3rd were reduced, but the number of cured cows were gradually increased. The cured cows after hormonal treatment were performed service repeatedly and the cumulative conception rate were increased. The cows treated with hormones at first service, the conception rate were follicular cyst 26%, luteal cyst 64.1%, endometritis 38.7%, mucometra 40%, pyometra 20.5%, respectively. The cumulative conception rates were increased by repeated service follicular cyst 57.3%, luteal cyst 84.6%, endometritis 67%, mucometra 75%, pyometra 64.1%, respectively.

To evaluate the functional status of ovarian cyst in Korean native cows, progesterone ($P_4$) and estrogen ($E_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian cysts were classified as single follicular cyst 51 cows (59.3%), multiple follicular cysts 19 cows (22.1%), single luteal cyst 13 cows (15.1%) and multiple luteal cysts 3 cows (3.5 %) by anatomical and ultrasonography. Ovarian cysts were classified as follicular cysts (54 cows), luteal cyst (16 cows) and non-functional ovarian cyst (16 cows) by hormone analysis, anatomical finding and ultasonography The luteal cyst was accurately diagnosed by cystic wall thickness, but follicular cysts was misdiagnosed 16 cows of 70 cystic cows The cystic fluid $P_4$ concentration was 3.3 ng/ml in follicular cysts and 30.1 ng/ml luteal cysts. There was significantly positive correlations between cystic wall thickness and serum $P_4$ concentration in follicular ($r^2=0.59$, p<0.001) and luteal cysts ($r^2=0.65$, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accurately diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts were not diagnosed only cystic diameter and cystic wall thickness.
