Adenomyotic cyst is very rare disease, their sizes are mostly lesser 5mm. The intrauterine adenomyotic cyst may arise from progressive expansion of cyst due to progressive menstrual bleeding. Authors experienced a case of large adenomyotic cyst within myometrium occuring in a l9-year-old woman, and who was accompanied with endometriosis. The cyst was about 3 x 3em sized, and had chocolate colored thick viscous contents, We experienced one case of adenomyotic cyst which was thought to be degenerated uterine myoma, so we report the case with a brief review of the concerned literatures.

Compared to other organs, the brain has limited antioxidant defenses. In particular, the hippocampus is the central region for learning and memory and is highly susceptible to oxidative stress. Glial cells are the most abundant cells in the brain, and sustained glial cell activation is critical to the neuroinflammation that aggravates neuropathology and neurotoxicity. Therefore, regulating glial cell activation is a promising neurotherapeutic treatment. Quinic acid (QA) and its derivatives possess anti-oxidant and anti-inflammatory properties. Although previous studies have evidenced QA’s benefit on the brain, in vivo and in vitro analyses of its anti-oxidant and anti-inflammatory properties in glial cells have yet to be established. This study investigated QA’s rescue effect in lipopolysaccharide (LPS)-induced behavior impairment. Orally administering QA restored social impairment and LPS-induced spatial and fear memory. In addition, QA inhibited proinflammatory mediator, oxidative stress marker, and mitogen-activated protein kinase (MAPK) activation in the LPS-injected hippocampus. QA inhibited nitrite release and extracellular signal-regulated kinase (ERK) phosphorylation in LPS-stimulated astrocytes. Collectively, QA restored impaired neuroinflammation-induced behavior by regulating proinflammatory mediator and ERK activation in astrocytes, demonstrating its potential as a therapeutic agent for neuroinflammation-induced brain disease treatments.

Muscular involvement of sarcoidosis is rare and occurs in two forms: nodular and myopathic. In the nodular variety, lesions are long and extend along muscle fibers. Axial MR imaging reveals a star-shaped central structure of decreased signal intensity. Sagittal and coronal MR images show three stripes: an inner stripe of decreased signal intensity and outer stripes of increased signal intensity. Longitudinal sonography shows an echogenic inner stripe and hypoechoic outer stripes. We report a case of nodulartype muscular sarcoidosis in a 53-year-old man, describing the findings of MRI and ultrasonography.

It hae been well established that, specifi alterations in members of the ras gene family, H-ras, K-ras and N-ras, can convert them into active oncogenes. These alterations are either point mutations occurirg in either codon 12, 13 or 61, or alternatively, a 5- to 50-fold amplification of the wfld-type gene. Activated ras oncogenes have been found in a significant proportion of all turnors, but the incidence varies considerably with the tumor type : it is frequent (20~40%) in colarectal eancer and acute myeloid leukemia, but absent or preaent rarely in breast and atomach cancer. But the role of c-K-ras point mutatio in the development of cancers in the female genital tract has not been extensively studied. Polymerase chain reaction followed by gel electrophoresis was performed respectively using wild-type normal and specific point mutation primers{GGT->GAT, GGT->AGT, GGT->TGT and GGT->GTT) to detect, point, mutation of codon 12 of c-K-ras oncogene. The c-K-ras oncogene point mutation was confirmed by Southern blot hybridization using synthetic oligonucleatide probe. 3'-end Iabelled with digoxigenin -dUTP. With this method, the frequency of point mutation on codon 12 of c-K-ras oncogene was examined the tissues in 37 casea of ovarian cancer, 7 cases of endometrial cancer, 36 cases of the gestational trophoblastic tumor, 60 cases of cervical cancer. The relationship between the presence of a c-K-ras point mutation and clinicopathological characteristics of the female genital tract cancers were also analysed. The results were as follows; 1. The incidence of four point mutations on codon 12 of c-K-ras oncogene in 37 ovarian cancers was 45.9% (17/37) and distribution were 43.2% (16/37), 2.7% (1/37) and 0% (0/37) in GGT-->GAT, GGT-->AGT, GGT-->TGT, and GGT-->GTT, respectively. According to histological type, in ovarian cancers, The point mutation of K-ras oncogene waspositive in 45 % (10/22) of serous cystadenocarcinomas. The incidence of four point mutations on codon 12 among 37 patients with ovarian cancer according to histological type was 45.5 % (10/22) with serous cystadenocarcinoma, 57.1% (4/7) of mucinous cystadenocarcinoma. Comparing the positive rate of point mutations of K-ras oncogen among 37 patients with ovarian cancer with the clinical stage, point mutation was detected in 28.5% (2/7) of patients with stage I, 40.0% (2/5) with stage II, and 52.0% (13/25) with stage III/IV. There was no statistically significant increasement of point mutations with the advance of the clinical stage of ovarian cancer. Comparing the positive rate of point mutations of K-ras oncogen among 37 patients with ovarian cancer according to the histologic grade point mutation was detected in 50.0 % (2/4) 0f patients with grade I, 451.7 % (5/12) with grade II and 47.6 % (10/21) with grade III. 2. The incidence of point mutations of K-ras oncogen among 33 patients with ovarian cancer who were performed pelvic lymph node dissection was 57.1 % (12/21) of the patients with pelvic lymph node metastases and 16.7% (2/12) of the patients without pelvic lymph node metastases. There was statistically significant difference between the positive rate of c-K-ras point mutations and the pelvic lymph nodal status(P<0.05). 3. In 7 cases of endometrial cancer, positive rate of K-ras point was 42.8 % (3/7). Point mutations were also detected in 2 cases from 4 choriocarcinomas, but, the point mutation was only detected in 1 case from 60 cervical carcinomas. From these results, we may suggest that the point mutation on codon 12 c-K-ras oncogene are considered to be one of the important genetic change in the tumor formation and progression of ovarian of c-K-ras oncogene seems to be the one stop in the multistep process of tumor formation in ovarian cancer. Furthermore, the point mutation of c-k-ras gene could occur more frequently in the patients of ovarian cancer with pelvic lymph node metastases than in those without pelvic metastases, suggesting the orle in tumor progression. And we concluded that point mutation on codon 12 is comparable frequent in uterine endometrial carcinomas and have significance as an event that contributes to progrssion of endometrial cancers and choriocarcinoma, but cervical carcinoma do not appear to have c-K-ras point mutation in general. More studies will be necessary, but the detection of c-k-ras point mutation as the possibility of biological tumor marker to predict clinical outcome may be utilized in female malignancies.

PURPOSE: We attempted to evaluate the outcomes of a newly inaugurated surgical technique of laparoscopic pyloromyotomy with microscope and stab incision (MS-LP) with right upper quadrant transverse open pyloromyotomy (RT-OP), which were performed in a single institution. METHODS: The outcome variables in terms of total anesthesia time, operative time, postoperative emesis, time to full-enteral feeding, postoperative hospital stay, cosmetic result score, medical cost, and postoperative wound complications were compared between the MS-LP and RT-OP groups. RESULTS: Fifty-one consecutive pyloromyotomy cases were enrolled; MS-LP (n=33) and RT-OP (n=18). There was no difference in age, pyloric thickness, and preoperative electrolyte levels between the two groups. The total anesthesia time and operative time of MS-LP were not significantly longer than that of RT-OP. Time to full-enteral feeding and postoperative hospital stay were shorter in MS-LP (20.0±18.3 vs. 35.3±14.8 hrs. and 2.4±1.3 vs. 3.4±1.2 days; p=0.047 and 0.050, respectively). The cosmetic result score and medical cost were significantly higher in MS-LP (9.1±1.0 vs. 7.3±1.2 in terms of scores and 3,501,950±1,093,147 vs. 2,522,474±68,605 in terms of KRW; p=0.001 and 0.021, respectively). No difference in postoperative wound complications was observed between the two groups. CONCLUSION: Laparoscopic pyloromyotomy with microscope and stab incision may suggest recovery benefits with a shorter time to full-enteral feeding and postoperative hospital stay, as well as better cosmetic results than RT-OP. However, MS-LP may induce higher costs.

In a edentulous patient, various methods can be employed for prosthetic treatment using implants, such as implant-supported fixed prostheses, overdentures, hybrid prostheses, and implant assisted removable partial denture. In this case, in a patient with moderate to severe chronic periodontitis requiring full arch extractions, implants were strategically placed using computer-guided surgery. In the maxilla, due to inadequate bone quality and quantity leading to insufficient initial stability, delayed loading was implemented, and interim prosthesis was used during the osseointegration period. In the mandible, stable initial stability was achieved, allowing for immediate loading to reduce patient discomfort.Primary stability is considered the most crucial factor for obtaining immediate loading, so a thorough clinical and radiological evaluation of the remaining alveolar bone quantity and quality must be conducted before surgery.
