PURPOSE: The effects of 5HT3 receptor agonist and antagonist on rabbit intraocular pressure (IOP) and pupil size were evaluated. METHODS: A 5HT3 receptor agonist, I-Phenylbiguanide (PBG, 1%) and a 5HT3 receptor antagonist, 3-Tropanyl-indole-carboxylate methiodide (ICS-205,930) were applied topically to the rabbit eye, and intraocular pressure and pupil diameter were checked with a Tono-PenTM XL and a ruler. RESULTS: Topical application of 1% PBG significantly increased IOP by 4.6+/-1.2 mmHg (p<0.001) over a period of up to 2 hours, the IOP maximum reached at 1 hour and caused pupil dilatation by 3.3+/-0.3mm (p<0.001) over a period of up to 5 hours, the dilation maximum reached at 2 hour. Topical preadministration of 1% ICS-205,930 prevented a rise in IOP but did not counteract on the pupil dilatation brought about by 5HT3 receptor agonist. CONCLUSIONS: These findings indicate that topically applied 5HT3 receptor agonist could raise IOP and dilate pupil.

To study the possibility of attraction magnetic forces to expand maxillary arch, we used 2 big adult dogs, 2 small puppies, 1 small adult dog as experiments, and 1 small adult dog as a control. We measured the intercanine width and intermolar width and histologically observed in the suture and cervical and apex region of teeth and took occlusal X-rays to observe separation of suture line in the maxilla. The results were as follows: 1. Expansion velocities of intercanine (0.25mm/day) and intermolar widths (0.23mm/day) in puppies were faster than those (0.135mm/day, 0.09mm/day) in adults. 2. In all experiments in adults (0.135mm/day) and puppies (0.25mm/day), expansion velocity of intercanine widths were faster than those (0.09mm/day, 0.23mm/day) of intermolar width. 3. In all experiments ectatic changes were observed and cellularities of fibroblast increased in the suture line. Only in adults dogs the separations of palatal suture were observed in the occlusal X-ray view. 4. In the puppies bony deposition was particularly observed in the suture line and micro-bony fragments were often observed. 5. In the all experiments no root resorption was observed in the cervical and root area, but normal root resorption due to eruption of permanent teeth was observed in the puppies.

A 36-year-old female amateur cyclist developed mononeuropathy of the deep branch of the ulnar nerve due to nerve compression adjacent to the ulnar tunnel (type II Guyon’s canal syndrome) caused by prolonged bicycle riding.The patient’s signs and symptoms persisted even after refraining from cycling for 4 weeks; thus, she underwent decompression of the deep branch of the ulnar nerve in the palm and wrist. Three months postoperation, she recovered nearly full power and function of her left hand.

In microarray technology, many diverse experimental features can cause biases including RNA sources, microarray production or different platforms, diverse sample processing and various experiment protocols. These systematic effects cause a substantial obstacle in the analysis of microarray data. When such data sets derived from different experimental processes were used, the analysis result was almost inconsistent and it is not reliable. Therefore, one of the most pressing challenges in the microarray field is how to combine data that comes from two different groups. As the novel trial to integrate two data sets with batch effect, we simply applied standardization to microarray data before the significant gene selection. In the gene selection step, we used new defined measure that considers the distance between a gene and an ideal gene as well as the between-slide and within-slide variations. Also we discussed the association of biological functions and different expression patterns in selected discriminative gene set. As a result, we could confirm that batch effect was minimized by standardization and the selected genes from the standardized data included various expression pattems and the significant biological functions.

Intractable pain was controlled in 5 cases using dorsal root entry zone lesions. All patients had failed to conservative therapy. Dorsal root entry zone lesions were made to include the involved dermatomes added one half of the dermatomes above and below the painful areas. Four patient noticed good pain relief with follow up period ranging from 6 to 24 months. Patient whose lesions were performed using a CO2 laser mas suffered no complicated deficit. Dorsal root entry zone lesions appeared to be a satisfactory treatment for intractable pain in patients, who have failed to respond to more conservative mode of therapy.

Vascular injury caused by a central venous catheter (CVC) has been reported to be a rare complication, especially delayed vascular injury due to CVC has a few cases and it can be fatal because of delayed recognition and more serious complications. A 59-year-old woman with no available medical history was admitted for treatment of ovarian cancer. For the surgery, a triple-lumen CVC was placed through the left subclavian vein. Parenteral nutrition through the CVC was used for postoperative nutritional management in the first postoperative day. On the sixth postoperative day (POD), the patient suddenly complained of dyspnea. The CT revealed bilateral pleural effusion and irregular soft tissue density and air bubble in anterior mediastinum suggesting migration of the distal portion of the CVC into the anterior mediastium. In the intensive care unit (ICU) bilateral thoracentesis and percutaneous drainage were performed. She was discharged from the ICU in 3 days later and transferred to the general ward. This case emphasizes the possibility of the delayed vascular injury related to CVC and some strategies for prevention of vascular injury.

PURPOSE: The aim of this study is to investigate the clinical factors affecting on the cure rate by invasive and open surgery for gastric cancer and to establish a subgroup of patients who can be applied by the early recovery after surgery program through this retrospective analysis. MATERIALS AND METHODS: In this retrospective study, we analyzed 425 patients who underwent gastric cancer surgery between January 2011 and December 2011 and were managed with conventional clinical therapies. This clinical algorithm was made when the patient was in minimally invasive surgery group and discharged from hospital one day faster than them in open surgery group. RESULTS: The completion rate of the clinical pathway was 62.4%. Despite the different applications of clinical pathway, completion rate in minimally invasive surgery group was significantly higher than that of open group (P<0.001). In multivariate analysis, the surgical procedure of minimally invasive surgery (odds ratio=4.281) was the most predictable factor to complete clinical pathway. Additionally, younger patients (odds ratio=1.933) who underwent distal gastrectomy (odds ratio=1.999) without combined resection (odds ratio=3.069) were predicted to accomplish the clinical pathway without any modifications. CONCLUSIONS: We concluded that high efficacy of the clinical pathway for gastric cancer surgery was expected to selected patients through retrospective analysis (expected completion rate=85.4%). In addition, these patients would become enrolled criteria for early recovery program in gastric cancer surgery.

OBJECTIVES: To evaluate whether the day of delivery for women with regular menstrual history was predicted best from the last menstrual period (LMP), crown rump length (CRL) and or biparietal diameter (BPD). METHODS: All of 561 women had estimated the day of delivery by LMP, CRL in the first trimester (In case of 217 women, it was available) and BPD in the second trimester. The accuracy of each method in predicting the day of delivery was determined. Those who were delivered after the spontaneous onset of labor were included. Differences among these methods were evaluated with nonparametric tests. RESULTS: The percentage of women who delivered within 3 days of the estimated day of delivery was 254(45.3%) and 216(38.5%) of the women with pregnancies by BPD and LMP, respectively. And within 7days of the estimated day were 408(72.7%), 390(69.5%) of the women from BPD and the LMP. In the women, the BPD estimate was significantly better predictor within the 7days of the day of delivery than LMP estimate (p=0.027). Compared to LMP estimate, CRL and BPD estimates seemed to be advanced the day of delivery about 2.6 days in CRL, and 0.9 days in BPD (p=0.004, p=0.034). But we could not find any advantage of the CRL measurement in first trimester than single BPD measurement in the second trimester for the predictor of the day of delivery. CONCLUSIONS: When the difference between the methods in predicting the day of delivery was less than 7 days, the BPD measurement was better than the last menstrual period.

BACKGROUND: Simple ventricular septal defect(VSD) is the most common congenital heart disease. Although closure of VSD is currently associated with a relatively low risk, experience with younger and smaller infants has been variably less satisfactory. We assessed the results of surgical closure of VSD in infant. MATERIALS AND METHODS: Between 1996 and 2000, 45 non-restrictive VSD patients underwent patch repair and retrospective analysis was done. Patients were divided into two groups based on weight: group I infants weighed 5kg or less(n=16), and group II infants weighed more than 5kg(n=29). Both groups had similar variation in sex, VSD location, aortic cross clamp time and total bypass time. But combined diseases (ASD, PDA, MR) were more in group I. We closed VSD with patch and used simple continuous suture method in all patients. RESULTS: There were no operative mortality, no reoperation for hemodynamically significant residual shunt and no surgically induced complete heart block. As a complication, pneumonia(group I: 2 cases, group II: 2 cases), transient seizure(group II: 2), wound infection(group I: 1, group II: 1), urinary tract infection(group I: 1) and chylopericardium(group I: 1) developed, and there was no significant difference between two groups(p>0.05). CONCLUSION: Early primary closure with simple continuous suture method was applicable in all patients with non-restrictive VSD without any serious complications.
