Birds of Alas Purwo National Park, East Java

This paper details some of the more important and interesting records from Alas Purwo National Park in East Java. Most of these come from the author's work in the Park from May 1997 until September 1999, though records are included from many other sources. Details are given of the status of all of the species that are classed as threatened or near-threatened by Collar et al. (1994), along with those that are attitudinally or distributionally unexpected. A full systematic list of the species recorded in and around the Park is included, some 227 to date (with an additional 11 'possible' species)

Studies of organic anion and cation transport in isolated segments of proximal tubules

The transport of organic anions and cations has interested physiologists for many years despite the generally held view that these transport mechanisms are involved principally in the elimination of foreign substances and metabolites from the body. The clearance and excretion of para-aminohippurate (PAH) has been used an an index of renal plasma flow, and the maximal rate of PAH secretion has been assumed to reflect the mass of functioning renal tissue in patients [1]. Clinicians also utilize the fractional excretion of urate as a guide to volume sufficiency of the extracellular fluid compartment and quantify the excretion rate of this organic solute in the evaluation of gout and urolithiasis [2]. The renal excretion of organic cations has been of principal interest to renal pharmacologists, although there is increased awareness among clinicians that this system is important in the regulation of endogenous levels of organic bases [1]
