The purpose of this study was to evaluate the systemic and local production of immunoglobulins and their levels in patients with periapical cysts using Enzyme - Linked Immunosorbent Assay. Streptococcus sanguis, Bacteroides gingivalis, and Bacteroides intermedius were grown for use as antigen and they were harvested by centrifugation. The patients were divided into two groups: patients of periapical cysts and normal control. 5 patients of each group were selected and their blood were obtained via intravenous puncture prior to surgical operation. Sera were prepared by centrifugation of each blood samples. Cyst fluid were aspirated from cystic cavity and cyst wall were excised at operation. Control tissue were also excised at extraction site of impacted wisdom teeth from normal control. Each tissue was prepared by homogenization and centrifugation. Then antibodies of each sample were measured by modified ELISA. The following results were obtained: 1. Serum IgG and IgM levels were not significantly different between patients with periapical cyst and normal control. 2. IgG and IgM levels of cyst fluid to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of serum of patients with periapical cyst, but there was no significant difference to Streptococcus sanguis. 3. IgG and IgM levels of cyst wall to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of control tissue, but there was no significant difference to Streptococcus sanguis. 4. IgG and IgM levels in cyst fluid and IgG levels in cyst wall were highest to Bacteroides gingivalis, and IgM levels in cyst wall were highest to Bacteroides intermedius.

We have experienced 3 cases of papillary carcinoma of the thyroid gland seen as lateral neck cyst, Usually cystic lesions of the neck have been considered as benign lesions from clinical viewpoint. The usual differential diagnosis includes branchial cleft cyst, cystic hygroma, dermoid cyst, cold abscess(tuberculous lymphadenitis) and cavitating squamous cell carcinoma. A lateral neck cyst as the sole presenting complaint of the papillary thyroid carcinoma is very rare. Preoperative diagnosis of lateral neck cyst is often diagnostic dilemma. Fine-needle aspiration cytology can be helpful in detecting the cancer cells and in demonstrating the nature of the fluid component of the lateral neck cyst. Presence of brown murky fluid from the aspirated fluid is highly suggestive of thyroid carcinoma. The thyroid scans and B-mode ultrasonography mayor may not be helpful to detect the primary focus of the thyroid gland. We suggest that a patient with a lateral neck cyst in adult age group should be considered to be a possibility of underlying thyroid carcinoma presanting as lateral neck cyst.

Spinal extradural arachnoid cyst (SEAC) is a rare disease and has surgical challenges because of the critical surrounding anatomy. We describe the rare case of a 58-year-old woman who underwent extradural cyst total excision with dural repair and presented with refractory cerebrospinal fluid (CSF) leakage even though two consecutive surgeries including dural defect re-repair and lumbar-peritoneal shunt were performed. The authors covered the sacral defect using bilateral gluteus maximus muscle flap in tongue in groove and wrap around pattern for protection of visible sacral nerve roots and blockage of CSF leakage point. With the flap coverage, the disappearance of cyst and fluid collection was confirmed in the postoperative radiological finding, and the clinical symptoms were significantly improved. By protecting the sacral nerve roots and covering the base of sacral defect, we can minimize the risk of complication and resolve the refractory fluid collection. Our results suggest that the gluteus muscle flap can be a safe and effective option for sacral defect and CSF leakage in extradural cyst or other conditions.

After collecting calcareous corpuscles from plerocercoid of Spirometra mansoni (sparganum), we evaluated the antigenic values of calcareous corpuscles binding proteins obtained from the cyst fluid of Taenia solium metacestodes. Immunoblot analysis revealed that cysticercosis patient sera strongly recognized 10 and 95 kDa calcareous corpuscles binding proteins. This result demonstrated that calcareous corpuscles are bound with major secretory antigenic proteins, which is possibly involved in the secretory pathways of the 10 and 95 kDa proteins presenting in the cyst fluid of T. solium metacestodes.

The 150 kDa protein of cyst fluid (CF) of Taenia solium metacestodes was purified by ammonium sulfate fractionation and Superose 6 HR gel filtration chromatography. The purified protein consisted of three subunits (15, 10 and 7 kDa proteins), which were analyzed with the use of a 7.5-15％ gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SOS-PAGE). Immunofluorescence study was carried out by using immunize specific polyclonal antibody. Positive reactions were noticed at bladder walls, calcareous corpuscles, granules of cyst fluid and some host tissue surrounding the bladder wall of the metacestodes. These results suggest that the 150 kDa protein was secreted into host tissues, inducing immune responses in the host, and it may play important roles in the cellular physiology of the parasites.

The authors have interpreted one patient's full mJuth intra-oral films, oblique- lateral film of the left mandible and orthopantomograph which revealed 6 radicular and 1 residual cysts. As a results of interpretation of these serial films, we have drawn following conclusions: 1. Radicular cyst arose from the cell rests contained in an apical granuloma which was sequel to advanced pulpitis due to dental caries. 2. Residual cyst was developed from remaining cell rests after the extraction of a tooth with such a radicular cyst or apical dental granuloma. 3. Cyst grew in size by absorption of fluid into cystic cavity due to difference in osmotic pressure between the cystic fluid and adjacent tissue fluid.

Bronchogenic cysts, though known as a relatively common malformation of the mediastinum, were rarely discussed in Korean literatures. Since the surgical removal of asymptomatic lesions was adopted as the reasonable therapeutic principle, the incidence of bronchogenic cysts were found to be higher than previously expected. Two cases of bronchogenic cysts operated on in The Dept. of Thoracic Surgery, Korea University Woo Sok Hospital were reported and related literatures were reviewed. Case 1. 5 year old boy with chief complaints of bulging cystic mass on left supraclavicular region during straining or coughing since his age of 2 was admitted, and cystogram with Lipiodol revealed hen-egg sized mass in the left antero-superior mediastinum without any communication with bronchus or esophagus. Cyst was successfully removed under general anesthesia thru left supraclavicular incision, and pathological examination of the cyst revealed thin cystic wall lined with stratified columnar epithelium and it`s content was milky white mucoid fluid devoid of any bacterial growth. Case 2. 15 year old school girl has been noted slowly growing walnut-sized mass on anterolateral side of the neck for 4 months without any subjective symptom except cosmetic problem... Mass was aspirated to find milky white mucoid fluid in some loculation and yellowish turbid fluid in other part due to chronic infection. Cystic tumor was removed under local anesthesia, which was loculated in between the trachea and esophagus without any communication, and pathological diagnosis of the cyst was bronchogenic cyst with columnar epithelial cell lining with moderate chronic inflammatory cell infiltrations. Postoperative conditions of the two cases were all excellent with normal life.

Spinal extradural meningeal cyst has been rarely reported, whose etiologies are assumed to be the communication of cerebrospinal fluid (CSF) between intradural subarchnoid space and cyst due to the congenital defect in dura mater. Although the CSF communication due to this defect can be found, in most case, few cases in which there is a lack of the communication have also been reported. We report a case of the huge extradural meningeal cyst occurring in the thoracolumbar spine (from T10 to L2) where there was a lack of the communication between the intradural subarachnoid space and cyst in a 46-year-old man who presented with symptoms that were indicative of progressive paraparesis and leg pain. The patient underwent laminectomy and cyst excision. On intraoperative findings, the dura was intact and there was a lack of the communication with intradural subarachnoid space. Immediately after the surgery, weakness and leg pain disappeared shortly.

To establish the differential diagnosis and functional status in ovarian cystic cows, progesterone(P$_4$) and estrogen(E$_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian follicles were classified as systic if the diameter was greater than 25 mm by ultrasonography. Ovarian cysts < 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and >10 ng/ml E$_2$ concentration were classified follicular cyst, ovarian cysts 3 mm of cystic wall thickness, 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified luteal cyst, and ovarian cysts 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified non-functional ovarian cyst, respectively. Also ovarian cysts were classified 8 types by anatomical and hisctological findings. Ovarian cysts with corpus luteum were 3 of 73 cows and ovarian cysts without corpus luteum were 70 cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Aa 56.2%, 2Ba 20.5% and 2Ab 15.1%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 76.7% and luteal cyst 19.2%. The thickness of cystic wall were lAb 3.9 mm, 2Ab 3.3 mm and 2Bb 3.2 mm, and the cystic fluid P$_4$ concentrations were above 10.0 ng/ml in lAb, 2Ab and 2Bb, respectively. There was significantly correlations between the thickness of cystic wall and cystic fluid P$_4$ concentration in ovarian cysts(p<0.05). The ovarian cyst was classified follicular cysts, luteal cyst and non-functional ovarian cyst by hormone analysis. The luteal cyst was accuratly dignosed by cystic wall thickness. But follicular cysts was misdiagnosed 13 cows of 56 cystic cows. The 13 cystic cows was determined as had non-fuctional ovarian cysts. The cystic fluid P$_4$ concentration was 3.3 ng/ml in follicular ovarian cysts and 30.1 ng/ml luteinized ovarian cysts. There was significantly positive correlations between thickness of cystic wall and serum P$_4$ concentration in follicular(r$^2$ =0.59, p<0.001) and luteal cysts(r$^2$=0.65, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accuratly diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts was not diagnosed only cystic diameter and cystic wall thickness. In conclusion, it is suggest that ovarian cysts was diagnosed by combination of clinical sign and anatomical cystic features.

We report a rare complication of iatrogenic spinal intradural following minimally invasive extradural endoscopic procedues in the lumbo-sacral spines. To our knowledge, intradural cyst following epiduroscopy has not been reported in the literature. A 65-year-old woman with back pain related with previous lumbar disc surgery underwent endoscopic epidural neuroplasty and nerve block, but her back pain much aggravated after this procedure. Postoperative magnetic resonance imaging revealed a large intradural cyst from S1-2 to L2-3 displacing the nerve roots anteriorly. On T1 and T2-weighted image, the signal within the cyst had the same intensity as cerebrospinal fluid. The patient underwent partial laminectomy of L5 and intradural exploration, and fenestration of the cystic wall was accomplished. During operation, the communication between the cyst and subarachnoid space was not identified, and the content of the cyst was the same as that of cerebrospinal fluid. Postoperatively, the pain attenuated immediately. Incidental durotomy which occurred during advancing the endoscope through epidural space may be the cause of formation of the intradural cyst. Intrdural cyst should be considered, if a patient complains of new symptoms such as aggravation of back pain after epiduroscopy. Surgical treatment, simple fenestration of the cyst may lead to improved outcome. All the procedures using epiduroscopy should be performed with caution.
