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.

The present observation was focussed mainly on the histopathological and immunohistochemical finding of the tumor developing from the outside of rat uterus wall. In gross finding, this tumor were a oval form mass and 0.75cm and 1cm in greatest demension. The sectioned surface showed uniform, solid, gray-white. In histopathological finding, the tumor showed the form of lymphoid nodule-like structure and was composed of the cells with karryorrhexis, karyolysis and necrosis in the central zone, mature cells in the paracentral zone, and concentric layers of compressed, flattened and atrophied smooth muscle fibers by the proliferating of the cells closely resembling endometrial stromal ells in the peripheral zone and a few smaller nodule-like structure in certain areas of the peripheral zone. In immunohistochemical observations, the proliferating cells presents only among the concentric layers of the smooth muscle fibers in the peripheral zone. Labeling index of proliferating cells in the peripheral zone was $4.34{\pm}1.28%$. These tumor cells did not metastasized in another orgns and labeling index was low, So it was concluded that this tumor was benign stomal sarcoma.

The author studied the actions of autonomic drugs on the uterine muscle isolated from Ditrema temmincki Bleeker, and the results obtained were summerized as follows. 1) The motility of the fish uterus was stimulated by epinephrine, norepinephrine and phenylephrine, but inhibited by isoproterenol. 2) The inhibitory effects of isoproterenol on the fish uterus was not affected by phenoxybenzamine, but blocked by propranolol. 3) The excitatory effects of phenylephrine on the fish uterus were blocked by phenoxybenzamine, but stimulated by propranolol. 4) The excitatory effects of epinephrine and norepinephrine were reversed by phenoxybenzamine and stimulated by propranolol. 5) The motility of the fish uterus pretreated with phenoxybenzamine and propranolol was not affected by isoproterenol, phenylephrine, epinephrine and norepinephrine. 6) It seemed that the uterine muscle of the fish had both alpha excitatory and beta inhibitory receptors. 7) The motility of the uterus of the fish was stimulated by acetylcholine. The stimulating action of acetylcholine was antagonized by atropine. 8) The motility of fish uterus was not affected by nicotine and DMPP. The actions of these drugs were not affected by pretreatment with hexamethonium and atropine. 9) It is, therefore, concluded that there are not present ganglia cells furnished with cholinergic fiber in the uterine wall of the fish.

Pyometra is a diestrual, chronic disease process with acute manifestations in the adult, ovary-intact bitch. Serosal inclusion cysts develop during postpartum involution as mesothelium becomes trapped during rapid uterine contraction. A 10-year-old golden retriever bitch presented with lethargy, anorexia, tachypnea, abdominal distention, and abnormal vaginal discharge. Radiographic, ultrasound, and laboratory examinations were performed. On ultrasound examination, the uterus was distended by fluid containing echogenic "snow storm" particles; cystic structures containing anechoic fluid were found adjacent to the body of the uterus. Leukocytosis, neutrophilia, and anemia were diagnosed by a complete blood cell count. The initial diagnosis was pyometra, and an ovariohysterectomy was performed. Macroscopically, the uterine body and horns were expanded and partially adhered to the abdominal wall; numerous cysts containing clear fluid protruded over the entire surface of the uterus. Escherichia coli that was sensitive to enrofloxacin, was cultured from the lumen of the uterus. Histopathological assessment confirmed a final diagnosis of pyometra and serosal inclusion cysts of the uterus.

The study was designed to investigate the effects of progesterone on the reproductive system. This investigation was performed by immunohistochemical methods using anti-bromodeoxyuridine-antibody following bromodeoxyuridine(Brdur) injection for labeling proliferating cells in the uterus and ovary of rats. Sixteen female rats(Wistar), weighing initially 300g, were randomly allotted into ovariectomized and unovariectomized large groups. These two large groups were subdivided into three subgroups of control, 3-day and 6-day groups, respectively. 3-days and 6-days group were injected with 1mg of progesterone/rat/day for 3 or 6 days, respectively. In gross findings, the uterus of ovariectomized groups markedly atrophied, and were not hypertrophied by progesterone injection for 3 days or 6 days and the uterus of unovariectomized groups also were not hypertrophied. Labeling index(LI, %) was measured by counting the number of Brdur-positive cells from 300 to 3,000 cells per layer in the uterus tissue. The average LI of the uterus in unovariectomized groups was higher than that of ovariectomized groups. The subgroups with higher LI in unovariectomized groups were ordered as 6-day group, 3-day group. So progesterone considerably effected to the proliferating of the cells in the uterus of unovariectomized groups. The layers with higher LI in the uterus wall were ordered as the functional zone of endometrium, epithelial layer of endometrium, basal zone of endometrium, myometrium and perimetrium. The cell types with higher LI in the uterus of unovariectomized groups were ordered as the surface epithelial cells, stromal cells, glandular epithelial cells and muscle cells. Growing follicles with proliferating cells from secondary and tertiary follicles in the ovary of unovariectomized groups appeared to be 37.66% in control group, 39.23% in 3-day groups, 39.47% in 6-day groups. Mature follicles in the ovary were more number in control group than those in 3-day groups but not appeared in 6-day groups. So progesterone not nearly effects to the number of the growing follicles but appeared to be related to suppression of the development and protrusion of the mid-tertiary and mature follicles on the ovary surface. The cell types with higher LI in the ovary of unovariectomized groups were respectively ordered as granulosa cells, theca interns cells in secondary follicles; theca interna cells, granulosa cells, theca externa cells in tertiary follicles; fibroblasts, theca in terns cells in atretic follicles; fibroblasts, luteal cells in corpus luteum.

Uterus myoma is a benign tumor of smooth muscle in the wall of the uterus, In oriental medicine, we used to made an effort to management this patients without surgical operation. Doctors have treated patients of uterus myoma mainly by checking over each symptom they have. Then we think that patients have some symptoms in relation to an etiological cause. So I have carried out this study to investigate association of DSOM scores and an attack of uterus myoma in oriental medicine. We chose 3 groups, the first one is 257 uterus myoma patients who visited Dongeui University Oriental Medical Center from May 2001 to June 2006, the second one is 558 outpatients who didn't have uterus myoma from May 2005 to June 2005, the third one is 129 clinical trials who volunteered for Sasang constitutional medicine. Then we made up 3 groups to checkup DSOM, and investigated the All DSOM Fluents which effect uterus myoma patients using regression model. Logistic regression analysis indicate as follows ; In comparison with 558 outpatients data, blood stasis(血瘀), dryness(燥) is associated positively and insufficiency of Yang(陽虛), spleen(脾), phlegm(痰) negatively, and mean of the index for pathogenic factor(病機指標 平均) of deficiency of qi(氣虛), heart(心) negatively. In comparison with 129 clinical trials data, blood stasis(血瘀) is associated positively and phlegm(痰) negatively, and mean of the index for pathogenic factor(炳機指標 平均) of deficiency of Yin(陰虛), liver(肝), diarrhea positively, heart(心) negatively. 3. In investigation of DSOM items, items of blood stasis(血瘀), deficiency of Yin(陰虛), coldness(寒) is associated positively and items of heart(心), spleen(脾), Phlegm(痰) negatively.

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.

Objective: Tyrosine phosphorylation is an essential process in many biological systems, including the male reproductive system. The presence of tyrosine-phosphorylated (TyrPho) proteins has been well documented in male reproductive organs, but research in fertile females is still limited. Methods: The ovary, oviduct, and uterus of adult female Sprague-Dawley rats in the estrus phase were used to localize TyrPho proteins using an immunohistochemical technique. These proteins were separated and their expression patterns were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot analysis, respectively. Results: TyrPho proteins were localized in the cytoplasm of the oocyte except the antral fluid; in the granulosa cells, theca cells, and stromal cells of the ovary; at the apical surface of oviductal epithelial cells; and in the basal epithelium and submucosa of the uterine wall. Moreover, we found that 72-, 43-, and 28-kDa TyrPho proteins were localized in the ovary, while 170-, 55-, and 43-kDa proteins were localized in the oviduct. In the uterus, we detected four major bands, corresponding to 61-, 55-, 54-, and 43-kDa TyrPho proteins. Conclusion: Given that these TyrPho proteins were found in major reproductive organs in the estrus phase, these proteins may play important roles in female fertility.

At the time of visiting, the cat was 6-year-old female Siamese cat. The mammary mass was solid and firm and measured $2{\times}5cm^2$ in greatest diameter. The uterus revealed thick uterine horn and cross sectioned wall. Histopathologically, the mammary mass revealed feline mammary carcinoma. In the uterus, cystic endometrial hyperplasia was observed. Feline leukemia virus positive reaction was detected by polymerase chain reaction. As far as we know, this is the first report of the simultaneous feline mammary carcinoma and uterine endometrial cystic hyperplasia with Feline leukemia virus infection in a cat.
