1.Imunological characterization of antigens from cysticercus and sparganum and their application to immunodiagnosis 1. Immunological characteristics of crude antigenic components from Cysticercus cellulosae.
The Korean Journal of Parasitology 1988;26(4):245-254
We studied the serological reaction between various antigenic components from Cysticercus cellulosae and IgG antibodies in sera of cysticercosis, sparganosis, hydatidosis patients and normal humans by ELISA and EITB. In serological tests by ELISA, we recognized cross reaction of Cysticercus antigenic components with IgG antibodies in heterologous sera such as sparganosis and hydatidosis patients or normal humans. The crude antigenic components of Cysticercus showed lower ELISA sensitivity in homologous sera from cysticercosis patients than heterologous sera from hydatidosis patients. A total of 31 polypeptide bands with 260 KDa-22 KDa molecular weights were detected by SDS-PAGE, and 11 of them showed strong intensity. Total 22 components of them were recognized by IgG antibodies in cysticercosis patients sera. However, 12 of them were recognized also by normal human sera, 11 were by sparganosis sera, and 21 were by hydatidosis patients sera. The crude antigenic components of 104 KDa, 82 KDa, 72 KDa, 59 KDa and 34 KDa molecular weights were nonspecific ones, which cross-reacted with sera of either cysticercosis, sparganosis, hydatidosis patients or normal humans.

OBJECTIVE: Attention Deficit/Hyperactivity Disorder(ADHD) and tic disorders are relatively common childhood onset neuropsychiatric disorders, and these two disorders frequently cooccur in some individual. Although the efficacy of psychostimulants is well established in ADHD, as many as 25% of children fail to respond to psychostimulant treatment due either to a lack of efficacy or to intolerable side effects including exacerbations of tics. Guanfacine, a selective alpha2A-adrenergic agonist, was recently introduced for the treatment of children with ADHD. This study is to evaluate the efficacy and safety of guanfacine in children with ADHD and comorbid habit disorders and to identify subgroups of children who may have a more favorable response to guanfacine. METHODS: Twenty five children who were 6 to 16 years old were enrolled in an open trial of guanfacine for two months. Primary outcome measures were DuPaul Parent and Teacher Rating Scales, Conners Parent and Teacher Rating Scales and Yale Global Tic Severity Scale. Paired t-test and multiple logistic regression were performed to evaluate symptom improvement and to examine predictor variables for positive drug response. RESULTS: Severity of ADHD symptoms and tics after guanfacine administration was significantly reduced at each follow-up point in the ratings completed by both parents and teachers and in clinical evaluation, compared to their pre-medication status. Children with moderate ADHD symptoms responded more favorably to guanfacine than children with mild or severe symptoms. CONCLUSION: These findings suggest that guanfacine may be a safe and an effective medication for ADHD children who cannot benefit from psychostimulants, but more definitive research strategies are needed for future investigation.

Monoclonal gammopathy of renal significance is defined as any B cell or plasma cell clonal lymphoproliferation which neither causes tumor complications nor meets any current hematological criteria for specific therapy, with one or more kidney lesions related to the produced monoclonal immunoglobulin, such as amyloidosis. A 50-year-old male presented with heavy proteinuria and blood tests showing IgA and Lambda paraproteinemia. Light microscopy showed mesangial eosinophilic ground substance extending into the capillary loops, and positive staining within the glomeruli and vessel walls for amyloid P immunohistochemistry was also noted. Immunofluorescence showed positive staining for IgA and Lambda in the mesangia and capillary loops. Electron microscopy exhibited organized fibrils measuring 4–5 nm in diameter in the mesangia, glomerular basement membranes and vessel walls. We interpreted the overall findings as atypical renal amyloidosis with IgA and Lambda deposition on immunofluorescence. Further amyloid typing using laser microdissection-liquid chromatography and mass spectrometry will be useful.

7.Updates in the Relationship Between Human Rhinovirus and Asthma.
Allergy, Asthma & Immunology Research 2012;4(3):116-121
Human rhinovirus (HRV) is a nonenveloped, single stranded RNA virus belonging to the family Picornaviridae. HRV infections can cause both upper and lower respiratory illnesses in children and adults. Lower respiratory illnesses are more likely to occur in specific high risk groups, including infants, and children and adults with asthma. The relationships between rates of infection and the risk of clinical illness and exacerbation are not completely understood. Recent studies employing polymerase chain reaction and other molecular techniques indicate that there are new branches on the HRV family tree, and one characteristic of recently detected viruses is that they cannot be detected by standard tissue culture. Here we review the current literature and discuss new advances in understanding the link between HRV and asthma.

Anterior clinoid process is a small bony structure but it is very important regarding its location and relationships with neighboring neurovascular, dural, and bony structures. Removal of this process has been used in various modification of standard pterional approach. The authors have speculated how much expansion of operative window could be obtained with anterior clinoidectomy, so we measured the lengths of optic nerve, internal carotid artery, and the length and width of optico-carotid triangle(OCT) before and after extradural anterior clinoidectomy 17 times in 10 cadaveric heads. This procedure provided about two fold increase in the length of optic nerve and OCT, and over three fold expansion in the width of OCT. The results indicate that the addition of this relatively simple and easy procedure to standard approach makes the operative field more comfortable and safe than expected. We believe this procedure can be used routinely with or without combination of wide skull base exposure in cases of such lesions as belows: 1) lesions causing optic nerve or chiasmatic compression, 2) lesions encircling/covering the optic nerve and internal carotid artery, 3) lesions arising from or extending into the optic canal, orbital apex, and paraclinoid region, 4) suprasellar/parasellar lesions with limited operative windows(e.g. prefixed chiasm, infra-optic or subchiasmatic locations or adherence).

10.Viral Infections and Associated Factors That Promote Acute Exacerbations of Asthma

Despite asthma being the most common chronic childhood ailment, there is still much to learn about the disease. Early childhood infections with well-known or emerging viruses can lay the pathophysiologic framework for asthma development and exacerbation later in life, which may be due partly to alteration of the airway microbiome. Once asthma is established, acute exacerbations are usually associated with infections with respiratory viruses, such as rhinoviruses (RVs). Once again, there are bidirectional interactions between viruses and airway bacteria that appear to influence the severity of illness and the likelihood of exacerbation. Studies employing recent advances in viral and bacterial identification analytic techniques will clarify these new concepts and may provide the basis for new treatments or prevention or respiratory infection-associated exacerbation. This paper is a review of the associations among respiratory viruses, bacteria, inflammatory mechanisms, and asthma exacerbation.
