PURPOSE: Both headache and obesity are prevalent and chronic conditions among children. A well-known pathophysiology of migraine is that calcitonin gene-related peptide (CGRP) is an important postsynaptic mediator of trigemino-vascular inflammation. Plasma CGRP levels have been shown to increase in obese individuals during the headache phase of migraines. The purpose of this study was to assess the relationship between headache and plasma CGRP levels in obese children. METHODS: We prospectively studied plasma CGRP levels in 33 patients (20 overweight and obese subjects without headache, 13 overweight and obese subjects with headache) who visited Chosun University Hospital from March 2009 to September 2009. Blood samples were collected from cubital veins and plasma levels of CGRP were measured by radioimmunoassay. RESULTS: The mean age was 12.3+/-2.3 (range 6-15 years) and mean CGRP level was 19.1+/-2.5 pg/ml in the overweight and obese with headache group and 17.4+/-5.1 pg/mL in the overweight and obese without headache group. In the group CGRP levels lower than 19 pg/mL, mean headache frequency per month, mean severity, and mean disability were 17.0+/-18.4, 4.0+/-2.8 and 2.0+/-0.0, respectively. In the group with CGRP levels of 19 or greater pg/ml, levels were 11.0+/-9.8, 5.6+/-1.0, and 23.1+/-8.2, respectively. CONCLUSION: The mean CGRP level in overweight and obese children with headache was not significantly higher than in those without headache (P =0.202). Further, there was no significant correlation between CGRP level and frequency, severity of headache, and disability due to headache (P > 0.05). Further studies are needed to access the relationship of CGRP and pediatric headache in obese subjects.

Takayasu's arteritis is briefly as an inflammatory process of unknown etiology occuring dominantly in young female most commonly involving the great vessels arising from the aortic arch. The disease process results in stenosis and obliteration of involved vessels. Syncope in Takayasu's arteritis is known to result from decreased blood flow to brain because of stenosing blood vessels. We herein describe a case of paroxysmal atrioventricular block in a 40-year old man with Takayasu's arteritis. The patient presented with spontaneous recurrent syncope associated with paroxysmal AV block. Carotid sinus pressure repeatedly induced paroxysmal AV block and syncope. Carotid sinus pressure after pretreatment of atropine failed to induce AV block or syncope. Coronary angiogram was normal. We concluded that syncope in this patients was attributed to carotid hypersensitivity rather than decreased blood flow to the brain due to vessel stenosis.

2 patients of forearm deformities with ulnar defect and radial head dislocation were treated with the Ilizarov apparatus at Chungnam University Hospital. One patient had a severe hypoplastic remnant-like ulnar fragment and a anterolaterally dislocated radial head due to complicated osteomyelitis of ulnar. We applied an Ilizarov apparatus to transport the radial head distally, and fixed to remaining proximal ulnar fragment. The other had a large bony defect at the ulnar shaft and a dislocated radial head due to complicated osteomyelitis of ulna. We performed internal transport of ulna to decreased the ulnar defect and to descend the dislocated radial head. The clinical-radiological features and functional results of those 2 forearm deformities were described with brief review of the articles about the Ilizarov method for correction of forearm defor- mities.

Lectin is a non-immunological glycoprotein and binds specifically to carbohydrate terminals in tissue. Lectin histochemistry using 10 different biotinylated lectins was performed to investigate the effects on thirty-two pigmented rabbit retinas during wound healing. The results are as follows: 1) In normal retina. a) WGA, RCA I, and LCA were bound to the internal limiting membrane. b) WGA, RCA I, LCA, and PNA were bound to the photoreceptor layer. c) WGA, RCA I, LCA, SJA, ConA and BSL I were bound to the basal side of retinal pigment epithelium. d) PNA was bound to cone cell only. e) SBA, DBA, and UEA I didn't bind to any layers of retina. 2) In photocoagulated wound. One day after photocoagulation WGA, LCA and RCA I began to show increased reaction. At 3 and 5 days these lectins sustained reactivity. At 7 days increased reactivity began to decrease or disappear from wound. Macrophages had positive reaction to BSL I, WGA, LCA, and RCA I. In conclusion these results indicate that a-mannose, a glucose, a, beta-galactose, N-acetylglucosamine, and N-acetylneuramic acid are present in glycoconjugates of normal rabbit neural retina. It seems that some glycoconjugates may be related to vitreoretinal, retinal and chorioretinal adhesion in normnal retinal, and after argon laser photocoagulation. WGA-binding, LCA-binding and RCA I-binding glycoconjugates may play a part in cell adhesion during early wound healing.

Nifedipine is the Ca++ channel blocker, of which action mechanism is blocking the calcium influx through the smooth muscle of vessels. It is known that Nipine(R) improve the visual field by increasing blood supply to the optic nerve with dilatation of vessels in low tension glaucoma patient whose visual field loss is thought to be caused by the ischemic change of optic nerve. We have clinically evaluated the sensitivities of visual fields of 7 cases (11 eyes) of low tcnsion glaucoma, who were medicated with Nipinetension glaucoma patient whose visual field loss is thought to be caused by the ischemic change of optic nerve. We have clinically evaluated the sensitivities of visual fields of 7 cases (11 eyes) of low tcnsion glaucoma, who were medicated with Nipine(R), 1Omg Tid per os for more than 2 weeks. The visual fields were tested at least 3 times or more with Humphrey automatic perimetry (Allergan, Statpac) and were divided into 10 sectors according to the nerve fiber bundles. In each sector, we analyzed the change of light sensitivity and global index, then compared by Student Pared t-Test. After medication of Nipine(R), improvements of mean light sensitivity in total sectors were found in 7 eyes among the 11 eyes and also superonasal portion of their visual field was more recovered than the other portions and they showed the improvement of the mean deviation but it was not significant.

The ultraviolet radiation (UVR) is known to be a potent modulator of many host immune functions and the exposure of experimental animals to the inflammatory effects of UVR induces depressions in their ability to initiate and effectuate various types of cellular immune responses. In this study, the effects of UV-B (280 320 nm) radiation on resistance to a facultative intracellular bacterium, Listeria monocytogenes (LM), were examined at the cellular level. The numbers of cultivable LM recovered from the spleens of UV-B-irradiated mice were decreased at 2 days postinfection compared with those of untreated control mice. However, the acquired immunity, developed 7 days after immunization with streptomycin (SM)-sensitive LM, in either UV-irradiated, LPS- or IL-1-pretreated mice was less stronger than that developed in untreated, control mice. To elucidate the possible mechanisms underlying the observation that UVR did increase innate immunity but decreased acquired immunity of mice to the infection with LM, the effects of UVR of mice on the production of IFN-r by activated splenocytes and TNF-a by peritoneal macrophages were assessed. Activated splenocytes from UV-irradiated mice exhibited a reduced capacity to produce IFN-r and cultured peritoneal macrophages produced more TNF-a in the presence of LPS during 24 hours after UV radiation. Though TNF-r activity was not detected in the sera of LM-infected mice, intravenous LPS injection induced TNF-r production and UVR decreased TNF activity in sera obtained from LM-infected mice with LPS induction 9 days after irradiation. Although Ia-negative macrophages were predominant in the peritoneal macrophages from untreated control mice, the infection of mice with LM caused a marked increase in Ia expression on peritoneal macrophages. However, UVR resulted in decreased expression of Ia molecule on the peritoneal macrophages during the LM infection. These findings suggest that the dual effects of UVR on the innate and acquired immunity of mice to the LM infection may be associated with altered capacities of splenocytes and peritoneal macrophages of the mice to produce cytokines, in addition to decrease of la molecule expression on the macrophages.
