    Notes: Hypersensitivity reactions can occur after the administration of barium products and all caused by one of the many additives. These reactions are extremely unusual. Authors report on a patient who developed urticaria shortly after a conventional barium examination.

    Notes: Abstract The measurement of locomotor activity (LA) of theophylline (Th) nontolerant (10 mg/kg, p.o.) rats using agonist and antagonist of different neurotransmitters either in single or in their different combinations suggest that an inhibition of central GABAergic activity as well as adenosinergic and serotonergic activities through the stimulation of dopaminergic activity followed by an inhibition of cholinergic system may stimulate LA in Th nontolerant condition. Further, it is suggested that the development of tolerance to Th restored the LA to control value may be due to an activation of adenosinergic system which possibly withdrew the inhibition occurred in central cholinergic, GABAergic and serotonergic activities followed by the modulation of dopaminergic system.

    Notes: Abstract This paper discusses the nature and consequences of institutional innovation being pursued in recent years for the organization and management of minor irrigation in Bangladesh. The comparative analysis presented in this paper suggests that there are no significant variations of performance between the mainstream management institutions, except that tubewells under BRDB-Cooperative groups performed less well than others, nor are there any significant associations between major technical factors and irrigation performance (other than nominal pump capacity). What appears to be more important is that the economic institutions such as payment system for water is strongly associated with productivity and equity performance; sharecropping with water, which has emerged, or been popularized, with the privatization programme, has negative impact on productivity and skews benefits of irrigation towards pump owners and managers. It is concluded that so far imperfectly designed institutions, for example privatization of equipment, appear to have failed to give rise to greater technical and allocative efficiency or equity.
