Abstract
Hypokalemic periodic paralysis (hypoPP) is a rare channelopathy caused by mutations in skeletal muscle ion channels that usually occurs in young individuals and adolescents. The etiology can be attributed to various factors, such as idiopathic or secondary causes. It is characterized by episodes of sudden flaccid muscle weakness. Timely detection may mitigate the risk of severe complications. Secondary causes of hypoPP, such as hyperthyroidism, should be ruled out, as this could lead to thyrotoxic periodic paralysis. We report the case of a 19-year-old boy who presented to the ED with severe weakness in both the upper and lower extremities. The weakness rapidly progressed to his trunk and was accompanied by acute urinary retention. The physical examination was significant for bilateral upper and lower extremity weakness. Subsequent laboratory investigations revealed markedly low serum potassium levels. The patient's symptoms resolved after the replacement of potassium, and he was discharged without neurological deficits. Although rarely accompanied by acute urinary retention, hypoPP must be differentiated from other causes of weakness and paralysis so that the proper treatment can be initiated quickly. The rarity of hypoPP, a condition seldom encountered in clinical practice, and the added rarity of its coexistence with acute urinary retention further underscore the uniqueness of this case report.

Abstract
Pulp necrosis is an uncommon sequel to extrusive luxation in immature teeth with incomplete apical closure. In this report, we describe the management of severely extruded immature maxillary incisors and the outcome of revascularization to treat subsequent pulp necrosis. An 8.5-year-old boy with severe dentoalveolar trauma to the anterior maxillary region as a result of a fall was provided emergency treatment consisting of reduction of the dislodged labial cortical bone and repositioning of the central incisors, which had suffered extrusive luxation. When he presented with spontaneous pain involving the traumatized incisors a week later, the teeth were treated via a revascularization protocol using sodium hypochlorite irrigation followed by 3 weeks of intracanal calcium hydroxide, then a coronal seal of mineral trioxide aggregate and resin composite. Complete periradicular healing was observed after 3 months, followed by progressive thickening of the root walls and apical closure. Follow-up observations confirmed the efficacy of the regenerative treatment as a viable alternative to conventional apexification in endodontically involved, traumatized immature teeth.

Abstract
Resorption of the distal root of primary second molars is a common consequence of ectopically erupting permanent first molars. Here, we report 2 unusual cases of primary molar root resorption caused by reversible (self-correcting) ectopic eruption of premolar and canine teeth. In both cases, severe pathological resorption of the mesial roots of primary molars was detected on routine dental radiographs, and the affected molars remained asymptomatic until exfoliation. The purpose of this paper was, using 2 case studies, to highlight the possibility of primary root resorption as a sequel of self-corrected ectopic eruption in locations not frequently diagnosed or reported.

Abstract
In a light-dark choice situation, the alpha(2) adrenoceptor antagonists yohimbine and idazoxan had different effects: idazoxan decreased time spent in the fit box, but yohimbine did not. The effects of idazoxan were not blocked by the alpha(2) adrenoceptor agonist clonidine. The benzodiazepine receptor antagonist Ro 15-1788 itself decreased time spent in the lit box, but in the presence of Ro 15-1788, idazoxan did not cause any further reduction.

Abstract
Previous experiments revealed that the cholinergic deficit in rats with a partial fornix section was accompanied by an increase in turnover of noradrenaline (NE) in the hippocampus. This noradrenergic hyperactivity contributed to the cognitive deficit in lesioned rats, probably by interaction with the cholinergic system. The present experiment examines the reorganization of the noradrenergic system after the damage induced by partial fornix section and attempts to determine if the increase in NE turnover is of locus coeruleus (LC) origin, or if it is a result of local regulation at the noradrenergic terminals. Rats were submitted to knife-cut section of the fornix, resulting in a decrease in choline acetyltransferase activity in the hippocampus, correlated with a significant behavioral deficit in a spatial memory task. Lesioned rats learned a nonspatial memory task normally. Sections of brains of these rats were submitted to quantitative autoradiography. [125I]Iodopindolol binding was assessed in the dorsal and ventral hippocampus to determine availability of beta receptors. This was found to be significantly lower in lesioned rats. [125I]Iodoclonidine was used to determine alpha 2 receptors binding in dorsal and ventral hippocampus and in LC. There was no difference in alpha 2 receptors in LC, a significant decrease in dorsal regions of the hippocampus, and a significant increase in ventral regions. Muscarinic M1 receptors in the hippocampus showed no changes after the lesion.

Abstract
Subcellular distribution of aminoacyl-tRNA synthetase activities has been studied in normal rabbit liver and under experimental myocardial ischemia (EMI). An increase in the activity of a number of aminoacyl-tRNA synthetases in postmitochondrial and postribosomal supernatants from rabbit liver has been determined 12 hr after EMI. Gel chromatography of the postribosomal supernatant on Sepharose 6B shows that aminoacyl-tRNA synthetase activities are distributed among the fractions with M(r) 1.82 x 10(6), 0.84 x 10(6) (high-M(r) aminoacyl-tRNA synthetase complexes) and 0.12-0.35 x 10(6). In the case of EMI aminoacyl-tRNA synthetase activities are partly redistributed from the 1.82 x 10(6) complex into the 0.84 x 10(6) complex. The catalytic properties of both free and complex leucyl-tRNA synthetases have been compared. KM for all the substrates are the values of the same order in norm and under EMI. A decrease in some aminoacyl-tRNA synthetase activities associated with polyribosomes has been observed 12 hr after EMI. The interaction of aminoacyl-tRNA synthetases with polyribosomes stimulates the catalytic activity of some enzymes and protects them from heat inactivation in vitro. It is assumed that the changes in association of aminoacyl-tRNA synthetases with high-M(r) complexes and compartmentalization of these enzymes on polyribosomes may be related to the alteration of protein biosynthesis under myocardial ischemia.

Abstract
In a light-dark choice situation, the alpha-2 adrenoceptor antagonist idazoxan shows anxiogenic-like effects, which cannot be blocked by the alpha-2 adrenoceptor agonist clonidine, or by the benzodiazepine receptor antagonist Ro 15-1788. In a conditioned conflict situation, both idazoxan and the alpha-2-adrenoceptor yohimbine show anxiogenic-like effects; the effect of idazoxan could not be blocked by clonidine or Ro 15-1788. These data suggest that systems other than alpha-2 adrenoceptors or benzodiazepine receptors must be found to explain these anxiogenic-like properties.

Abstract
The effect of the alpha 2 antagonist, idazoxan (IDA), on the excitability of neurons in the dentate gyrus of the hippocampus was studied. Population field potentials (PS) evoked by stimulation of the perforant pathway were measured before and after drug treatment. IDA enhanced the amplitude of the PS, while decreasing the slope of the EPSP. Neurotoxic destruction of noradrenergic nerve terminals completely abolished the IDA effect, arguing that its mechanism of action is through enhanced release of noradrenaline (NA). It is proposed that NA enhances the EPSP-to-spike coupling component of the PS.
