This study was undertaken to determine the normal serial ultrasonographic appearance of the postpartum uterine involution in small pet dogs (Yorkshire terrier and Maltese). Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored by ultrasonography in 12 small pet dogs. Serial ultrasonographic examinations were done daily during the first week, 3 days interval from 8 to 30 days, and weekly from 31 to 100 days postpartum. The excretory period of vaginal discharge in 12 normal bitches of uterine involution was finished completely within 3 weeks postpartum. The short axis shape of the uterus was initially often flaccid-appearing. It varied from circular to polygonal. This lasted until 15.75$\pm$3.84 days postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was a beaded appearance until 30.89$\pm$4.25 days postpartum. After 30 days, it was appeared as tubular shape between placental and interplacental sites. The ultrasonographic image of the postpartum uterus consisted of four echogenicity distinct layers. Uterine wall was represented as very hyperechoic serosa, hypoechoic myometrium, hyperechoic endometrium and anechoic structures of fluid in the uterine cavity until 7 days postpartum. The individual uterine layers were most prominent during the first week postpartum, and they became progressively less distinct throughout the course of uterine involution. The thickness of myometrium was decreased rapidly in the placental sites from 4.47$\pm$1.42 mm at 1 day to 1.92$\pm$0.26 mm at 16 day, and in the interplacental sites from 3.19$\pm$0.61 mm at 1 day to 1.39$\pm$0.61 mm at 16 day. And it was decreased slowly until 94 day and was been minimum thickness at 94 day. The thickness of endometrium was also decreased like that of myometrium. The uterine diameter in the placental sites was decreased from 22.28$\pm$3.01 mm at 1 day to 16.11$\pm$1.46 mm at 7 day, and in the interplacental sites was decreased from 13.65$\pm$2.34 mm at 1 day to 9.41$\pm$1.59 mm at 7 day postpartum. From 7 day to 93 day, the change of diameter was more and more slow. At 94 days postpartum, the uterine diameter was 5~6 mm both placental and interplacental sites, and the uterine horns were uniform hypoechoic, tubular structures without enlargement. Therefore, complete involution of the uterus occurred at 94 days. It was concluded that normal post partum uterine involution in small pet dogs appeared to be completed 94 days postpartum by gross findings such as vaginal discharges, and by ultrasonographic findings, uterine shape and echogenicity.

Objectives: Since early developed measurement of Postpartum depression(PPD) doesn't reflect physical symptoms, we need to find out how PPD and related physical disorders are expressed in functional medical methods. The study was conducted to find out characteristics of 7 Zone diagnosis and postpartum physical symptoms on PPD. Methods: To 216 postpartum women who did normal delivery, we measured 7-zone-diagnosis Factor AA's height on 5th day and 15th day postpartum. And we surveyed EPDS and postpartum physical symptoms question on 15th day postpartum. Subjects were divided into normal and depression group by EPDS score. And we compared Factor AA's height between two groups and Factor AA's height change in each group. Results: In depression group, Factor AA's height was higher than normal group on 5th day and 15th day postpartum. In both groups Factor AA's height was decreased on 15th day compared to 5th day postpartum. In normal group 2, 6, 7 zone were significantly decreased and in depression group only 6 zone was significantly decreased. Conclusions: These results demonstrate that postpartum depression group has low recuperative power. And these can be judged by Factor AA's height change.

This study was undertaken to determine the normal appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in 8 Miniature Schnauzer dogs. Vaginal discharge was observed visually during the 3 weeks of postpartum. A large amount of viscous dark green discharge changed progressively to a small amount of transparent discharge. In the uterine shape, the transverse images were crescent or polygonal at the beginning, but became circular after 16 days. At postpartum day 24, the longitudinal images of placental and interplacental sites were similar to each other The echogenicity of uterine structure was clearly distinguishable among the hyperechoic serous membrane, hypochoic myometrium, hyperechoic endometrium, and anechoic uterine contents during the first week postpartum, but afterward the interluminal boundaries and echogenicity became obscure gradually. In addition, the anechoic substance of the endometrial cavity was not observed after postpartum day 28. In the uterine diameter, the diameter of placental sites decreased markedly from 24 mm at the first day postpartum to 13 mm at day 7, and the diameter of interplacental sites decreased from 15 mm at postpartum day 1 to 10 mm at day 7. At postpartum day 65, the uterus (6.4 mm) changed little and had a uniform homogenous echo, and thus it was confirmed that uterine involution was completed at that time in Miniature Schnauzer dogs.

Ultrasonographic appearance of the normal involution process of the porcine postpartum uterus was examined. Six, sows were used to determine the normal Ultrasonographic appearance of the involution postpartum uterus. Ultrasonographic examinations were performed daily from days one through eight, then on days 15 and 21 postpartum. Ultrasonographic the mean local uterine wall thickness was 12.00 mm on day one postpartum. By day 15 the mean total uterine wall thickness was about 7.21 mm and on day 21 postpartum the uterus was about 6.12 mm. From one day to five days postpartum, intraluminal contents were isoechoic to the endometrium. From 15 days to 21 days, the luminal 7ont7llts were of mixed echogenicity compared to the endometrillm.

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.

This study was attempted to investigate the processes of regression of the corpus luteum and uterus after parturition in 2∼3 multiparous Korean native goats. The concentrations of LH, prolactin and progesterone in blood plasma of native goats were measured at 5 day intervals from 10 days prepartum to 35 days postpartum. The pregnancy corpus luteum from goats at Days(D) 1, 10, 20 and 30 days of postpartum were examined by light microscopy. Changes in the uterus fo goats were studies by macroscopic and light microscopic observations during the postpartum period. Mean concentrations of plasma LH were low after parturition and the levels of plasma LH were similar during late gestation and throughout the postpartum period. Mean plasma concentrations of prolactin were 0.30 0.06 and 0.38 0.13ng/ml at Day 5 and Day 10 prepartum, respectively, but PRL levels remained slightly high for 5 weeks after kidding. Mean levels of progesterone in plasma were 0.33 0.05ng/ml on Day 1 postpartum(P<0.01). Through light microscopic survey, pregnancy corpora lutea were quite degeneration by day 10 pospartum. Microscopic changes of CL regression consisted of cytoplasmic eosinophilia and vacuolation, and pyknosis and karyorrhexis of the nucleus of luteal cells. Vascular changes were distended at the periphery ofthe CL. From macroscopic measurements of the uterus, the uteri were returned to their initial non-pregnant stage within a period of 21 dyas after parturition. Following partuition the intercaruncular epithelium was reparied by 20 days. The uterine epithelium was partially recovered in the carucle by 30 days postpartum.

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 study was carried out the normal serial ultrasonographic appearance of the postpartum uterine involution with small pet bitches. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in small pet bitches (Miniature Schnauzer, Cocker Spaniel and Shih-tzu). In the Miniature Schnauzer bitches, uterine diameter of the placental sites and interplacental sites were decreased from $24.31{\pm}1.65\;mm$ at 1 day to $13.56{\pm}0.76\;mm$at 7 day, and $15.19{\pm}1.28\;mm$ at 1 day to $10.41{\pm}0.76\;mm$ at 7 day postpartum. In the Cocker Spaniel, the placental sites and interplacental sites were decreased from $24.90{\pm}1.62\;mm$ at 1 day to $14.14{\pm}1.21\;mm$at 7 day, and $15.33{\pm}1.47\;mm$ at 1 day to $10.19{\pm}0.83\;mm$ at 7 day postpartum. In the Shih-tzu, the placental sites and interplacental sites were decreased from $23.96{\pm}1.55\;mm$at 1 day to $13.84{\pm}0.94\;mm$ at 7 day, and $14.93{\pm}1.29\;mm$ at 1 day to $9.98{\pm}0.84\;mm$ at 7 day postpartum. And uterine diameter was no statistically significant difference among bitches (p>0.05). At 67 days, the uterine diameter in Miniature Schnauzer bitches were 6~7 mm both placental and interplacental sites, and the uterine horns showed uniform hypoechoic, tubular structures without enlargement. In present study, the involution of the uterus was completed at 67 days after parturition in Miniature Schnauzer, and 65 days in Cocker Spaniel and the Shih-tzu. There were no significant differences of normal postpartum uterine involution between small pet bitches (p>0.05). In conclusion, the postpartum involution of small pet bitches appeared to be completed normally at 65~67 days after parturition and could be identified by gross findings such as vaginal discharges and ultrasonographic findings of uterine shape and echogenicity.

Purpose: This study aimed to identify the scores of postpartum depression(PPD) on the first day, 1st week, and 6th week after the delivery and to explore their related factors before and after delivery in postpartum women. Methods: With a survey design, 293 postpartum women were recruited from a postpartum unit, Ilsin Christian hospital in Pusan via convenience sampling and were followed at 1st week and 6th week in the outpatient clinic. Results: Results showed that the scores of PPD(EPDS score) were low at postpartum 1st day, 1st week and 6th week but prevalence of PPD(EPDS ${\geq}13$)was 3.1%at 1st day, 8.2%at 1st week and 7.5%at 6th week, respectively. The pre-delivery factors were experience of depression, and the post-delivery factors were baby's sex(1st day), no caregiver for baby(1st week), and no help and concern for taking care of baby from husband and family(1st day and 6th week). The greater satisfaction with becoming a mother and her life, and greater maternal attachment were related to lower level of PPD at the three time points. Conclusion: Regular screening for postpartum depression and supportive and informative education is needed for postpartum women visiting the outpatient clinic for follow-up.

The effects of Sheng Hua Tang (SHT) on uterine involution and ovarian activity were investigated in postpartum dairy cows. SHT (70 g) was given to dairy cows (n = 10) to evaluate its effects for five days from the first postpartum day. Postpartum cows fed with a basal diet without SHT were used as the control group (n = 10). Ultrasounds and blood tests were recorded for four weeks from postpartum day seven with a 3-d interval. The results showed that the areas and diameters of endometria were significantly (p<0.01) reduced in the group that received SHT compared to the control group on the seventh postpartum day. The group that received SHT had an intrauterine fluid volume mean of $1.2{\pm}0.6cm^3$, which was significantly lower than that of the control group, $2.3{\pm}0.8cm^3$ (p<0.01) on the 13th postpartum day. In addition, the uterine tension score was a mean of $1.0{\pm}0.0$ in the group that received SHT, which was also significantly lower than that of the control group, $1.5{\pm}0.5$ (p<0.01) on the 19th postpartum day. Taken together, the Chinese herbal medicine remedy, SHT, promoted uterine involution and ovarian activity in postpartum dairy cows.
