This study estimated the degree of uterine inflammation and resumption of ovarian cyclicity in postpartum dairy cows. In addition, the prevalence of health problems during calving and the postpartum period was investigated. A total of 224 Holstein dairy cows from four dairy farms in Chungcheong Province were used for the study. Uterine discharge was scored on a 0 to 5 rank scale (metricheck score) using a metricheck instrument from 1 to 8 weeks postpartum and uterine cytology (neutrophil level) was examined at 4, 6 and 8 weeks postpartum to evaluate uterine inflammation. Resumption of ovarian cyclicity was evaluated based on progesterone analysis (${\geq}1ng/mL$) at 4, 6 and 8 weeks postpartum. Postpartum disorders were diagnosed by veterinarians in the research team. The metricheck score decreased linearly (p < 0.0001) from weeks 1 ($3.4{\pm}0.1$) to 4 ($2.0{\pm}0.1$) postpartum, and then remained at that level through week 8 postpartum ($1.6{\pm}0.1$, p > 0.05). The neutrophil levels determined by uterine cytology assays also decreased (p < 0.0001) from week 4 ($22.3{\pm}1.8%$) to 6 ($12.1{\pm}1.4%$) postpartum, and then remained at that level through week 8 postpartum ($9.2{\pm}1.4%$, p > 0.05). The proportion of cows exhibiting the ovarian cyclicity increased linearly (p < 0.0001) from weeks 2 (12.1%) to 8 (74.3%) postpartum. The prevalence of dystocia and retained placenta were 20.5% and 30.4%, respectively. The prevalence of ketosis, milk fever, abomasal displacement, septicemic metritis, endometritis, subclinical endometritis, pyometra, and ovarian cysts were 18.8%, 3.6%, 4.0%, 36.2%, 29.5%, 17.0%, 4.5%, and 14.7%, respectively. The prevalence of digestive problems and mastitis were 5.4% and 9.6%, respectively. The prevalence of culling and death were 4.0% and 3.6%, respectively. The prevalence of dystocia, retained placenta, septicemic metritis, endometritis, ovarian cysts, digestive problems, mastitis, and culling differed among farms (p < 0.05 to 0.01). In conclusion, proper examinations for uterine inflammation and ovarian cyclicity during 4 to 8 weeks postpartum are useful clinical tools to maintain herd reproductive health. Dystocia, retained placenta, septicemic metritis, and endometritis were predominant disorders in dairy cows of the survey area.

Purpose : Because adenocarcinomas of the uterine cervix have lower 5-year survival rate than squamous cell carcinomas due to early lymph node metastasis and local extension, scrutiny of lymph node metastasis and local extension by radiologic examination is necessary in case of clinically diagnosed or suspected adenocarcinomas. The purpose of this study is to evaluate whether there are specific findings of these tumors, compared with squamous cell carcinomas, through the analysis of magnetic resonance (MR) imaging findings. Materials and Methods : Of 21 pathologically proven cervical adenocarcinomas, MR imaging findings of 18 tumors (histologic staging : two Ib, four IIa, two IIb, one IIIa, and one IIIb) were retrospectively analyzed and compared with those of 40 wquamous cell carcinoma in consecutive patients as a control group. T1-wetighted and fast spin echo T2-weighted images were obtained on the axial and sagittal planes, using a 1.5-T MR scanner. The largest diameter, location, signal intensity and degree of contrast enhancement contour, shape and longitudinal extent of the tumor and associated findings on MR image were analyzed. Results : The largest diameters of cervical adenocarcinomas ranged from 0.8 to 4.1 cm(mean, 2.2 cm). Of 18 adenocarcinomas, nine were of endocervical type. All adenocarcinomas were isointense to surrounding cervical stroma on T1-weighted images and hyperintense(homogeneous in ten, inhomogeneous in eight) on fast spin echo T2-weighted images. Adenocarcinomas enhanced on contrast study in all patients (homogeneous in six, inhomogeneous in 12 with hyperintese enhnacing rim in two). Eight adenocarcinomas had smooth contours and ten had irregular ones. The shape of adenocarcinoma was irregular in eight patients, barrel shape in six, papillary/polypod in three, and nodular in one. All adenocarcinomas involved lower half of the uterine cervix and six tumors extended up to the upper half. Pelvic lymph nodes of more than 1.5cm in diameter in two adenocarcinomas pateints and no detectable small pelvic lymph nodes on MR imaging in one patient were pathologically positive. Hydrometra was associated in two adenocarcinomas patients, and hematometra in one patient. Compared with squamous cell carcinomas, more frequent MR findings of endocervical type and barrel shape in cervical adenocarcinomas were statistically significant. Conclusion : Cervical adenocarcinomas had more frequent MR findings of endocervical type and barrel shape, compared with wquamous cell carcinomas. Adenocarcinoma of the uterine cervix may be suspected on MR imaging, when a cervical carcinoma is of barrel shape along the endocervical canal and tends to involve lymth nodes in earlier stages.

Purpose To evaluate the safety and efficacy of the newly designed open-cell type self-expandable nitinol stent (NiTi-stent) for peripheral arteries. Materials and Methods Twenty-eight limbs of 14 minipigs were randomly assigned to the NiTistent group or conventional nitinol stent group. Stents were symmetrically implanted into the iliac arteries of each animal using carotid artery approach and were observed for 1 month (n = 5) and 6 months (n = 9). The angiographic lumen diameter (ALD), late lumen loss, angiographic stenosis, histomorphometric lumen area, neointimal area, and area stenosis were analyzed and compared between the groups. Results Stent migration, stent fracture, or thrombus formation were not observed in either group. At the 1-month follow-up, the neointimal area (p = 0.008) and area stenosis (p = 0.016) were significantly smaller in the NiTi-stent group than in the control group. At the 6-months followup, the NiTi-stent group showed significantly larger ALD (p = 0.014), less late lumen loss (p = 0.019), less angiographic stenosis (p = 0.014), larger lumen area (p = 0.040), and smaller neointimal area and area stenosis (p = 0.004 and p = 0.014, respectively) compared with the control group. Conclusion The NiTi-stent is as safe and effective as the conventional nitinol stent and induces less neointimal hyperplasia in a minipig iliac artery model.

The rupture of the aorta commonly follows major blunt trauma to the thorax. It has markedly increased in recent years, paralleling the rising number of vehicular accidents. The most frequent site of rupture is the area of the isthmus, with the ascending aorta second. The diagnosis of the condition from clinical data is difficult, and aortography is used whenever aortic tear is suspected. We are presenting a case of patient who had intimal tearing of the thoracic aorta with multiple injuries. The patient underwent surgical repair 28 days after injury with left heart [LA-Femoral artery] bypass.

In order to investigate reproductive disorder in dairy cows, 312 uterine from abattroirs and 56 cows from dairy farms were examined. The ovary and uterine were collected from abattroirs and rectal palpation was carried out in the case of reproductive disorder at dairy farm. Microbiological examination was also carried out from the collected samples. 1. Out of 312 ovaria from slaughter-house, cystic ovary and endometritis were classified as 51(16%) and 134(43%), respectively. And of 56 dairy cow from farms, 43(77%) were identifies as endometritis. 2. The main cause of reproductive disorder was classified as hormonal imbalances, endometritis and cystic ovary, singly or in combination. 3. The main causative agents of endometritis was encountered as E coli, Staphylococcus aureus, Bacillus sp and Corynebacterium sp. 4. The highest susceptible antibiotics to the isolates was cephalosporin.

Entrapment and fracture of coronary angioplasty hardware are rare complications of percutaneous coronary intervention (PCI). Retained guidewire should be removed either percutaneously or surgically, because it could serve as a nidus for thrombus formation. We report on a successful surgical retrieval of entrapped PCI guidewire and subsequent bypass grafting of the affected coronary vessel.

뇌헐혈증은 다양한 요인으로 유발될 수 있겠으나 궁극적으로는 국소적 뇌혈류량이 적정수준 이하로 감소됨으로 해서 초래된다. 이렇게 뇌혈류가 감소된 부위의 중심에는 이미 괴사가 일어난 부위도 있겠지만, 그 주위에 현재 뇌기능은 없으나 장차 혈류가 충분해 지면 소생 가능한 penumbra 영역이 있다. 이런 penumbra영역으로 다시 혈류가 충분히 보충되면 뇌기능이 소생되어 호전의 양상을 보이게 되나, 혈류가 계속 저하되어 있으면 비가역적 뇌손상을 받게 되어 증상이 악환된다. 병변 부위는 자율조절기능(autoregulation)이 파괴되어 혈관이 이완된 상태이기 때문에 측부혈행을 통하여 뇌혈류를 공급시키기기 위해서 혈압을 올리면서 혈액유동을 원활하게 해주는 보존적인 방법을 시행하면서 적응증이 되는 경우에는 수술적으로 외내경동맥문합술과 같은 여러 방법의 bypass혈관 수술이나 경동맥내막절제술로 뇌허혈 부위에 뇌혈류를 적극적으로 증강시켜 호전시킬 수 있다.

Objectives: The purpose of this study is to review the research in the cyclic treatment of endometriosis in traditional Korean medicine. Methods: By October 2019, the relevant studies on the periodic therapy of endometriosis were searched using the Chinese National Knowledge Infrastructure Database (CNKI) and Oriental Medicine Advanced Searching Integrated System (OASIS). Results: Finally, three Randomized controlled trials, one case study, two clinical observational studies were selected. In all studies, herbal medicine periodic therapy has been effective in improving symptoms of endometriosis. Blood-activating and stasis-dispelling medicinal were the most commonly used before menstruation and during menstruation, and tonifying and replenishing medicinal were the most commonly used after menstruation. According to the one study, which reported safety, herbal medicine was safe. Conclusions: Although limited due to a lack of literature, periodic therapy is effective in improving endometriosis related symptoms and preventing recurrence. A well-designed study and experimental studies for the identification of the mechanism are needed.
