Ultrasonographic studies were conducted on eight Murrah buffaloes daily from day 6 postpartum (pp) onwards till day 77 pp to monitor changes in the cervix, uterine horn and ovarian follicular growth and development. The mean size of horn and cervix on day six ($9.07{\pm}0.74$ and $8.58{\pm}0.00cm$) decreased significantly to $4.09{\pm}0.09$ and $3.56{\pm}0.08cm$ by day 27 pp, respectively. Follicles in 50% of the buffaloes ovulated within 24 to 54 days pp and the size of the largest follicle on different days increased to more than 5 mm. The remaining 50 percent of animals ovulated after 65 days postpartum. Large size follicles (>8.5 mm) appeared in six out of eight buffaloes between 10 to 30 days pp and five animals had ovulated during early postpartum period. Waves pattern of follicular growth was observed during early postpartum period. Ovulatory follicles growth rate was more than the anovulatory follicles and increase in size was more as compared to the subordinate follicle. Anovulatory follicles persisted for longer period. Mean size of large follicle was more from day 6 to 41 pp and again from 50 to 65 pp in cyclic animals. Second large follicle were large during early postpartum (18days), thereafter, its size was more in acyclic animals. Small follicles population was less in cyclic animals upto day 50 postpartum. Mean medium size follicle growth pattern did not differ in cyclic and acyclic groups. Large size follicle number was more in cyclic group (5/8) during 14 to 20 days postpartum. Presence of large follicles (>8.5 mm) showed initiation of ovarian activity.

This report describes a case of postpartum uterine rupture associated with retained placenta and sequential acute metritis, not dystocia. A 14-month-old Bichon Frise bitch presented with continuous vaginal bleeding. She delivered five puppies 3 days ago and expelled four placentas on the next day. After then, anorexia, acute depression with continuous vaginal haemorrhage developed. Plain radiography showed decreased serosal detail, and ultrasonography showed irregularly thickened uterine wall and ascites. Blood-tinged peritoneal fluid was an exudate with bacteria. Ovariohysterectomy was curative for the patient, and four full-thickness perforated holes were identified on both sides of the uterine horns.

Morphological changes in the uterine and vaginal epithelial cells of the Korean native goats were studied in fifteen primiparous goats slaughtered on the day of parturition and on days 1, 3, 10 and 21 postpartum. 15 uterus and vagina from goats were examined by scanning and transmission electron microscopy. The results obtained in this study were summarized as follows : 1. Transmission electron microscopically, long microvilli which sometimes ramified were found until 10 days postpartum, while short microvilli were found at 21 days. The high electron dense irregular-shaped mitochondria were found in the cytoplasm and the crystalline structure of the mitochondrial matrix was also found from 1 day to 10 days postpartum. Well-developed rough-endoplasmic reticulum (rER) with dilated cisternae which contained the proteins materials was observed at 21 days postpartum. These materials were fused each other and then large granules were found in the free surface of the cytoplasm. A few lipid droplets were generally appeared in the cytoplasm, while numerous droplets were found at 21 days postpartum. A moderate number of ribosomes, a few multivesicular bodies, vesicles, lysosomes and macrophages were found. The globule leucocytes were observed from 0 to 3 days postpartum by transmission electron microscopy. The short microvilli, high electron dense cytoplasm and severe indentation of the nuclear enbelope were found in the vaginal epithelium. Numerouos small vesicles and a few vacuoles were observed in the apical cytoplasmic portion of the epithelium. A few mitochondria were high electron dense and irregular in shape. A moderate amounts of microfilaments, loose intercellular space and dilated rER were also found at 21 days postpartum. 2. Scanning electron microscopically, the folds of the uterine mucosa were generally deep. The long microvilli of the epithelium were found until 3 days postpartum, while short microvili were found at 10 and 21 days postpartum. The distinct intercellular boundary was seen. The apporcine secretory profile of the epithelium observed at between 3 and 10 days postpartum and the cells were somewhat protruded into the lumen. The short microvilli were found on the surface of the protruded cells, while polygonal microridge profile of the epithelium and some dome-shaped epithelium were also observed at 21 days postpartum. The folds of the vaginal mucosa were deep and epithelium was polygonal in shape. The microvilli of the epithelium were long until 3 days postpartum, while they were short at 10 and 21 days. The polygonal epithelium was invaginated into the center of the cell surface until 10 days postpartum. The microridge and dome in shape of the epithelium were found at 10 days postpartum, while the polygonal and exfoliating epithelium were observed at 21 days.

These studies were carried out to examine the estradiol-17$\beta$ levelsin plasma and ovarian tissues, as well as the contents of collagen and catecholamines in the uterus, and to determine the effects of GnRH administrations of uterine involution in postpartum Korean native goats. Plasma concentrations of estradiol-17$\beta$ were 63.81$\pm$8.00 pg/ml at day 1 of kidding, declined to 36.78$\pm$22.90 ng/ml at day 24 and decreased progressively to 27.81$\pm$17.06 and 12.46$\pm$8.13 pg/ml at days 30 and 36 postpartum, respectively. In ovarian tissues, the concentrations of estaiol-17$\beta$ were increased just before parturition and decreased immediately after parturition. The plasma estradiol-17$\beta$ levels were slightly higher on days 12 and then decreased gradually after parturition. The concentraitons of estradiol-17$\beta$ in the ovaries of postpartum goats were increased at day 36 after treatments with GnRH. The total hydroxyproline contents in the uterus was slightly higher prior to parturition and decreased gradually with the postpartum intervals after parturition. Hydroxyproline concentraitons in the uterus were decreased at days 24 and 36 postpartum after treatments with GnRH. The norepinephrine concentrations in myometrium from the pregnant and postpartum goats were correspondingly low both immediately before and after partuition. Norepinephrine concentrations in the pregnant horn of the uterus were increased from days 12 to 36 of postpartum and those levels of the non-pregnant horn were also increased from days 24 to 36 postpartum. Slightly higher concentrations were present in the non-pregnant horn in comparison to the pregnant horn but these differences were not significant. Postpartum, the uterine norepinephrine concentration was slightly increased at day 36 after treatments with GnRH. Dopamine concentrations were greater than those of norepinephrine. The concentrations of dopamine in the uterus of pregnant goats was not significantly different from that in the postpartum animals. Dopamine concentraitons of pregnant horn in postpartum goats were increased at day 24 after treatments with GnRH.

Postpartum physiological, psychosocial, and economic changes bring with them some disorders of maternal mind and body, so postpartum management has been emphasized to date. After labor, some problems may appear like uterine bleeding, infection, depression and ache in or around joints. Some reports from traditional medical practitioners remark that over 50% of postpartum women have complaints within or around joints. For this study, arrangement of nomenclature, criteria and historical summarization are needed.

Objective: Bilateral uterine artery ligation (UAL) is a fertility-preserving procedure used in women experiencing postpartum hemorrhage (PPH). However, the long-term effects of this procedure on ovarian function remain unclear. The aim of this study was to investigate whether bilateral UAL compromised ovarian reserve and ovarian blood supply. Methods: This prospective study included 49 women aged between 21 and 36 years who had undergone a cesarean section for obstetric indications. Of these, 25 underwent uterine bilateral UAL to control intractable atonic PPH. The control group consisted of 24 women who had not undergone bilateral UAL. Standard clinical parameters, the results of color Doppler screening, and ovarian reserve markers were assessed in all participants at 6 months after surgery. The clinical parameters included age, parity, cycle history, body mass index, and previous medication and/or surgery. Color Doppler screening findings included the pulsatility index (PI) and resistance index (RI) for both the uterine and ovarian arteries. The ovarian reserve markers included day 3 follicle-stimulating hormone (FSH) levels, antral follicle count, and $anti-M\ddot{u}llerian$ hormone (AMH) levels. Results: There were no significant differences in the ovarian reserve markers of day 3 FSH levels, antral follicle count, and AMH levels between the study and control groups (p> 0.05 for all). In addition, no significant differences were observed in the PI and RI indices of the uterine and ovarian arteries (p> 0.05 for all). Conclusion: In this study, we showed that bilateral UAL had no negative effects on ovarian reserve or ovarian blood supply, so this treatment should be used as a fertility preservation technique to avoid hysterectomy in patients experiencing PPH.

A study on estrus synchronized dairy cows using progesterone intravaginal device was done to classify each cow's reproductive status from calving to synchronization and to evaluate the reproductive performance according to ovarian and uterine status, and calving season. From calving to estrus synchronization, silent heat or error of estrus detection among ovarian status and endometritis among uterine disorders were exposed in the most distribution (75.4% and 48.3%, respectively). The pregnancy rate of cows with inactive ovaries was lower than those in the follicular and luteal phase. And according to the uterine status before estrus synchronization, the pregnancy rate was similar in three groups; normal, endometritis, and pyometra (70.9, 69.1 and 100%, respectively). The interval from calving to conception was shorter (p<0.05) in cows calved during autumn than in cows calved during spring and winter.
