Abstract
Adverse reactions to drugs are not frequent in childhood. Cutaneous reactions are the most frequent in this age group. Mild cutaneous reactions are immediate or delayed adverse reactions that do not seriously compromise the clinical condition of children. The patients usually early improve and recover the state of health. Although it is difficult to define the prevalence accurately, we could affirm that the rate adverse reaction to drugs are often over estimated by both the families and the physicians. Therefore, children may be prone to loss of school days and inappropriate or sub-optimal treatments. However, the identification of a true adverse reaction to drugs allows adequate treatment and alert to further exposure to harmful drugs.

Abstract
Adverse drug reactions include drug hypersensitivity reactions (DHRs), which can be immunologically mediated or non-immunologically mediated. The high number of DHRs unconfirmed and/or self-reported is a frequent problem in daily clinical practice, with considerable impact on future prescription choices and patient health. It is important to distinguish between hypersensitivity and non-hypersensitivity reactions by adopting a structured diagnostic approach to confirm or discard the suspected drug, not only to avoid life-threatening reactions, but also to reduce the frequent over-diagnosis of DHRs.

Abstract
Antiphospholipid antibody syndrome (APS) is a disorder caused by circulating antibodies reacting with biological membranes and characterized by recurrent thrombosis, chronic thrombocytopenia and miscarriages. It has been reported to occur either as a primary syndrome or secondary to systemic autoimmune disorders. We describe a case of primary APS in a young patient, in whom the clinical course was particularly severe and complicated by a respiratory distress syndrome. The patient was resistant to a number of treatments, and eventually responded to intravenous high dose corticosteroids.

Abstract
Skeletal muscle becomes hyperexcitable following denervation and when cultured in the absence of nerve cells. In these circumstances, the bee venom peptide toxin apamin, a blocker of small-conductance calcium-activated potassium (SK) channels, dramatically reduces the hyperexcitability. In this report, we show that SK3 channels are expressed in denervated skeletal muscle and in L6 cells. Action potentials evoked from normal innervated rat skeletal muscle did not exhibit an afterhyperpolarization, indicating a lack of SK channel activity; very low levels of apamin binding sites, SK3 protein, or SK3 mRNA were present. However, denervation resulted in apamin-sensitive afterhyperpolarizations and increased apamin binding sites, SK3 protein, and SK3 mRNA. Cultured rat L6 myoblasts and differentiated L6 myotubes contained similar levels of SK3 mRNA, although apamin-sensitive SK currents and apamin binding sites were detected only following myotube differentiation. Therefore, different molecular mechanisms govern SK3 expression levels in denervated muscle compared with muscle cells differentiated in culture.

Abstract
An intermediate conductance calcium-activated potassium channel, hIK1, was cloned from human pancreas. The predicted amino acid sequence is related to, but distinct from, the small conductance calcium-activated potassium channel subfamily, which is approximately 50% conserved. hIK1 mRNA was detected in peripheral tissues but not in brain. Expression of hIK1 in Xenopus oocytes gave rise to inwardly rectifying potassium currents, which were activated by submicromolar concentrations of intracellular calcium (K0.5 = 0.3 microM). Although the K0.5 for calcium was similar to that of small conductance calcium-activated potassium channels, the slope factor derived from the Hill equation was significantly reduced (1.7 vs. 3. 5). Single-channel current amplitudes reflected the macroscopic inward rectification and revealed a conductance level of 39 pS in the inward direction. hIK1 currents were reversibly blocked by charybdotoxin (Ki = 2.5 nM) and clotrimazole (Ki = 24.8 nM) but were minimally affected by apamin (100 nM), iberiotoxin (50 nM), or ketoconazole (10 microM). These biophysical and pharmacological properties are consistent with native intermediate conductance calcium-activated potassium channels, including the erythrocyte Gardos channel.

Abstract
Intermittent cocaine administration produces sensitization, whereas the continuous administration of cocaine produces tolerance to the effects of subsequent cocaine administration during withdrawal. The present study examined whether the effects of these two dosing regimens are related to alterations in the functional status of dopamine (DA) D2 receptors. In all experiments, rats were withdrawn for 7 days from a 14-day pretreatment regimen involving either continuous or intermittent cocaine administration. Experiments examined changes in the behavioral response to an autoreceptor-selective dose of apomorphine, the effects of sulpiride on electrically stimulated DA release in striatal brain slices and striatal D2 receptor binding, and mRNA levels. The results indicate that the continuous administration of cocaine produces findings consistent with D2 autoreceptor supersensitivity; there was enhanced inhibition of behavior after the autoreceptor-selective dose of apomorphine, decreased electrically stimulated DA release in the absence of sulpiride, and enhanced electrically stimulated DA release in the presence of sulpiride. However, there were no changes in postsynaptic D2 receptor binding or mRNA levels. Intermittent cocaine administration did not produce evidence of D2 autoreceptor subsensitivity: there was no decrease in inhibition of behavior after the autoreceptor-selective dose of apomorphine, no changes in electrically stimulated DA release in the absence or presence of D2 receptor blockade, and no change in the levels of D2 receptor binding; however, D2 mRNA levels were decreased by 22%. Overall, the present results are consistent with the hypothesis that the expression of tolerance induced by continuous cocaine administration is associated with D2 autoreceptor supersensitivity.

Abstract
The sub-family of dopamine D1-like receptors is now known to be comprised of at least two members: the originally cloned D1 receptor (herein referred to as the D1a receptor) and a related receptor referred to as the D1b, D1 beta or D5 dopamine receptor (herein referred to as the D1b/D5 receptor). Here, we characterize the D1b/D5 receptor expressed transiently in COS-7 cells and permanently in Ltk- cells. Transiently expressed human D1b/D5 receptors bind the D1 specific ligand [125I]SCH 23982 saturably and with high affinity (KD = 500 pM). Competition for [125I]SCH 23982 binding to rat D1b/D5 and human D1a and D1b/D5 receptors supports the contention that the two D1b/D5 receptors are species homologues. Furthermore, in COS-7 cells, as previously observed, dopamine competes for the binding of [125I]SCH 23982 to human D1b/D5 receptors with a higher affinity than that seen at the human D1a receptor. These results are similar to those seen in Ltk- cells permanently transfected with the human D1b/D5 receptor. In these cells, dopamine competition for [125I]SCH 23982 binding is complex, sensitive to guanine nucleotides and of a higher affinity than that observed for dopamine binding to the human D1a receptor expressed in these same cells. In both D1a and D1b/D5 expressing Ltk- cells, dopamine stimulates adenylyl cyclase with an EC50 of approximately 200 nM. Furthermore, preincubation of Ltk- cells expressing the D1a and D1b/D5 receptors with dopamine results in desensitization of the response of adenylyl cyclase to subsequent agonist stimulation.

Abstract
Multiple D1 dopaminergic receptor subtypes have been postulated on the basis of pharmacological, biochemical, and genetic studies. We describe the isolation and characterization of a rat gene encoding a dopamine receptor that is structurally and functionally similar to the D1 dopamine receptor. The coding region, which is intronless, encodes a protein of 475 amino acids (Mr 52,834) with structural features that are consistent with receptors coupled to guanine nucleotide-binding regulatory proteins. The expressed protein binds dopaminergic ligands and mediates stimulation of adenylyl cyclase with pharmacological properties similar to those of the D1 dopamine receptor. The gene encoding the human homologue of this receptor subtype is located to the short arm of chromosome 4 (4p16.3), the same region as the Huntington disease gene. In striking contrast to the previously cloned D1 receptor, little or no mRNA for the receptor described here was observed in striatum, nucleus accumbens, olfactory tubercle, and frontal cortex. High levels of mRNA for this receptor were found in distinct layers of the hippocampus, the mammillary nuclei, and the anterior pretectal nuclei, brain regions that have been shown to exhibit little or no D1 dopamine receptor binding. On the basis of its properties we propose that this dopamine receptor subtype be called D1B.

Abstract
Aromatic L-amino acid decarboxylase (AAAD) activity of rat retina is low in animals placed in the dark. When the room lights are turned on, activity rises for almost 3 h and reaches values that are about twice the values found in the dark. A study of the kinetics of the enzyme revealed that the apparent Km values for L-3,4-dihydroxyphenylalanine and pyridoxal-5'-phosphate were unchanged in light- and dark-exposed animals, whereas the Vmax increased in the light. Treating the animals with cycloheximide before exposure to light prevented the increase of enzyme activity. Immunotitration with antibodies to AAAD suggested that more enzyme molecules are present in the light than in the dark. When the room lights are turned off AAAD activity drops rapidly at first and then more slowly, suggesting that at least two processes are responsible for the fall of enzyme activity. Exposure to short periods of dark followed by light results in a rapid increase of AAAD activity. Mixing homogenates from light- and dark-exposed rats results in activity values that are less than expected, suggesting the presence of an endogenous inhibitor(s). These studies demonstrate that AAAD activity is modulated in vivo.
