BACKGROUND: Bupivacaine is a amide type local anesthetic agent, widely used for its excellent quality of analgesia and long duration of action. But unintended intravenous injection causes severe complication such as convulsion and cardiovascular collapse, which is known for its difficulty in resuscitation. With all the study, the exact mechanism is still unclear and there are much debate on the method of resuscitation. METHOD: We studied the effect of clonidine pretreatment on bupivacaine-induced cardiac toxicity and resuscitation in anesthetized dog. Twelve dogs were divided into two groups. : saline pretreatment group (control, N=6) and clonidine pretreatment group (clonidine group, N=6). The dogs were anesthetized with N2O-O2-enflurane and vecuronium. Thoracotomy was done in 4th or 5th intercostal space for open cardiac massage. After confirming stability of vital signs, we administered clonidine (10 mcg/kg) or saline, and then administered bupivacaine with the rate of 2 mg/kg/min. When the electeocardiogram showed asystole, 20 mcg/kg of epinephrine was administered via central venous line and open cardiac massage with the rate of 120 beat/min. was performed. We observed electrocardiogram (lead II), arterial blood pressure, heart rate, dose of infused bupivacaine to be required for QRS widening and arrest, required time and administered dose of epinephrine for resuscitation. RESULTS: Clonidine group showed significant decrease of heart rate after pretreatment (p<0.05). There was no significant difference in required dose for QRS widening between two groups. The dose administered for inducing arrest was less in clonidine group than control group (p<0.05). The time required for resuscitation was shorter in clonidine group than control group (p<0.05). The total dose of epinephrine required for resuscitation was less in clonidine group than control group (p<0.05). The blood concentration of catecholamine did not showed significant difference during the whole course of experiment. CONCLUSIONS: Above results demonstrated that clonidine, a central nervous system-mediated sympatholytic agent, facilitated cardiac arrest when bupivacaine was infused intravenously and cardiac rescucitation.

There are two types of retinal macroglia: astrocyte and Muller cell. The major component of iintermediate filament in astrocyte is GFAP, recognized as the primary marker of astrocyte. Muller cells do not physiologically express GFAP in normal developing retina. A striking increase in GFAP expression. however, is observed in Muller cells under certain pathological condition. It is also suggested that this kind of changes of Muller cells in human retina is related with aging, and may be an early feature of pathogenesis of Age related macular degeneration. The goal of this study is to investigate the involvement of the human retinal macroglia in normal aging by immunogold labeling for electron. The goal of this study is to investigate the involvement of the human retinal macroglia in normal aging by immunogold labeling for electron microscopy. The sections of aged neurosensory retina showed the evidence of expression of GFAP by Muller cells. The results suggest, therefore, that Muller cells are induced to express GFAP during aging.

Retinal horizontal cell is second-order neuron that integrates the information from photoreceptors over large retinal areas, mediating the lateral spread of visual signals to distant retina. The Neurofilament proteins, considered as neuronal markers, have been imunolocalized to mammalian retinal horizontal cess. However, the immunolabeling of Neurofilament in human, has been focused on the studies of visual pathway and large ganglion cells The goal of this study is to see whether human retinal horizontal cells are indeed neuronal nature or glial nature by immunogold labeling for electron microscopy. The sections of 65 year-old human retina showed the expression of Neurofilament by horizontal cells, which confirms the evidence of human retinal horizontal cell as neuronal nature.

BACKGROUND: Diverticulosis of the cecum and ascending colon is a rare disease in Western countries, it is more common in the Orient. Making the diagnosis preoperatively could be difficult, and the intraoperative assessment and decision of optimal treatments are difficult. METHODS: Therefore, we reviewed the patient's charts of diverticulosis of the cecum and ascending colon at our hospital from 1992 to 1997. RESULTS: During the past 5 years, a total of 53 cases of diverticulosis of the cecum and ascending colon had been treated at this hospital. Mean age was 41.8 years (range 20-70). The male to female ratio was 1.8 : 1. Frequent complaints were abdominal pain (46 cases, 86.8%), followed by diarrhea (5 cases, 9.3%), indigestion (4 cases, 7.5%), and bowel habits change (2 cases, 3.8%). Mean duration of illness was 3.5 days(range 24 hours~15 days). In non-surgical cases, diagnoses were established with barium enema, CT scan, or ultrasonography. The accuracy of these methods was 91%, 75%, and 25%. In surgical cases, the preoperative diagnoses were appendicitis(13 cases, 50.1%), diverticulitis (7 cases, 31.8%), and abscess (2 cases, 9.1%). Treatments of the cecum and ascending colon diverticulitis were conservative management (3 teases,58.5%) and surgical treatment (22 cases,41.5%). The operative procedures were right hemicolectomies (2 cases), ileocecal resections (2 cases), diverticulectomies (6 cases) and appendectomies only (11 cases). CONCLUSION: These results suggest that correct diagnosis of the diverticulitis of the cecum and ascending colon made before treatment is very important because correct assessment of diverticulitis intraoperatively is difacut. Liberal use of diagnostic modalities could facilitate to make correct diagnosis to set a proper plan for treatment.

Craniofacial cleft is a rare congenital anomaly with a wide range of clinical manifestation and severity of deformity. In 1976, Tessier announced classification system on the basis of anatomical observation derived from clinical finding or operative dissection. Nowadays, this system is in common use because it is in accordance with terminology and observational finding and clinical manifestation is accordant with operative finding. Median facial cleft(No. 0-14 facial cleft) has a wide range of congenital malformation from a midline cleft upper lip to orbital hypertelorism, among which the bifid nose is frequently associated with hypertelorism. The manifestation of a bifid nose is variable from a simple central groove at the nasal tip to a complete clefting of the osteocartilaginous framework. In consequence, the planning of correction of the bifid nose must be individualized. We contrived correction of bifid nose using rib bone graft containing small amount of costal cartilage with maneuver of 2mm incision on nasal root skin together with fixation with 9mm miniscrew through an open approach in two No. 0-14 facial cleft patients with mild hypertelorism and bifid nose. With this method we could obtain satisfactory results in the standpoint of function as well as aesthetics. We think that this method is appropriate for correction of bifid nose of mild median facial cleft.

The biliary cystadenocarcinomas are very rare malignant tumor. The etiology is unclear, this tumor may be develop from malignant transformation of begin cystadenoma. The tumor appears typically as a cystic mass which contains papillary projections or internal septations. Papillary projections are seen on the inner surface of the cyst which present numerous papillary protrusion typical to this rare tumor. Excessive mucin secretion produced by the tumor cells and its retention in the common bile duct may cause bile stasis leading to obstructive jaundice. Common presenting symptoms are abdominal fullness, pain, nausea, palpable mass and asymptomatic. The available diagnostic tools are CT and sonography, but histologic examination can be made diagnostic confirm. Surgical resection yields excellent results. We were experienced a cystadecarcinoma with early gallbladder cancer, then report with reference.

PURPOSE: Thyroidectomy without prophylactic central neck dissection may be recommended for small (T1 or T2) papillary thyroid carcinoma (PTC). The aim of this study was to determine the incidence and predictive factors of central cervical lymph node metastasis in T1/2 papillary thyroid carcinoma. METHODS: A retrospective review of 877 patients with T1/2 PTC who underwent thyroidectomy and central lymph node dissection with or without lateral lymph node dissection from March 2007 to February 2014 was performed. The clinicopathologic results were reviewed and the incidence and predictive factors of central cervical lymph node metastasis (LNM) were analyzed. RESULTS: The overall frequency of central LNM was 29.8%. In univariate analysis, male, younger age, bilaterality, multifocality, larger tumor size, lymphovascular invasion, and lateral lymph node metastasis were associated with central LNM. In multivariate analysis, younger age, larger tumor size, lymphovascular invasion, and lateral lymph node metastasis were independent variables of central LNM. CONCLUSION: Central LNM is associated with younger age, larger tumor, lymphovascular invasion, and lateral lymph node metastasis in small (T1/2) PTC patients. Prophylactic central lymph node dissection should be considered in patients with risk factors.

The estrogen hormone receptor (ER) content of human breast cancer has assumed an important role as a predictor of hormone therapy response and as a prognostic indicator. The conventional technique is the dextran-coated charcoal (DCC) method or a ligand-binding assay (LBA) based on the measurement of radiolabeled steroids in cytosolic extracts of tissue homogenate. The recent introduction of monoclonal antibodies with high specificity for human ERs has allowed the application of immunocytochemical assays (ICA) in human cancer tissue. An extension of the ICA technique to cytologic specimens is also widely used. Our aim was to evaluate the reliability of ER-ICAs on fine needle aspirates(FNA) from breast cancer patients by comparing it with ER-ICAs and ER-LBAs performed on surgically removed tissues. During a recent 6-month period, ER-ICAs and ER-LBAs were performed in 83 cases. Among these 83 cases, only the 40 cases for which the ER-ICA and the ER-LBA were performed simultaneously ere included in this study. As positive cutoff values, we assumed 10 fmol/mg protein for the ER-LBAs and a semiquantitative score of 4 for the ER-ICAs. The results were as follows : 1) The ER positive rate was 55% (22/40) for ICAs and 47.5% (19/40) for LBAs. The concordance rate between the ER of ICAs and that of LBAs was 82.5% (33/40). 2) The Pearson correlation coefficient between ER-ICAs of fine needle aspirates and that of surgically removed tissue was good (r=0.94, p<0.005) 3) The Spearman correlation coefficient between ER-ICAs of fine needle aspirates and ER-LBAs of surgically removed tissue was good (r=0.57, p=0.0001) In conclusion, ER determination by using the fine needle aspirate is a reliable method in palpable breast cancer. FNA-ER may be a useful method when it is difficult to take sufficient breast cancer tissue, i.e., in cases of diffusely recurrent cancer, liver metastasis, malignant pleural effusion, etc.
