Abstract: Metabolic acidosis (MA) has been implicated in the pathogenesis of both osteomalacia and osteopenia. Alterations in the secretion of parathyroid hormone and in the metabolism of vitamin D may contribute to such skeletal changes. To minimize the influence of these factors, quantitative bone histology and measurements of bone formation using double tetracycline labeling were done in thyroparathyroidectomized (TPTX) rats with MA induced by ammonium chloride (TPTX-A), and in both non-acidotic TPTX (TPTX-C) and intact (C) controls. To evaluate the response of both cortical and trabecular bone to MA, histologic studies were done at three separate sites in the tibia, cortical bone from the mid-shaft, and trabecular bone from the epiphysis and from the metaphysis. Plasma pH was lower in TPTX-A, 7.24 +/- 0.10, than in either TPTX-C, 7.39 +/- 0.03, or C, 7.43 +/- 0.04, P less than 0.01, and urinary hydroxyproline excretion increased from 89.8 +/- 8.7 in TPTX-C to 150.2 +/- 25.9 micrograms/mg/creatinine in TPTX-A, P less than 0.01. Resorption surface at the epiphysis increased from 1.8 +/- 0.6% in TPTX-C to 4.0 +/- 1.6% in TPTX-A, P less than 0.05, values not different from those in C, 3.1 +/- 1.1%. Resorption surface was unchanged at other skeletal sites, but total bone volume at the metaphysis fell from 15.5 +/- 5.6% in TPTX-C to 9.0 +/- 4.3% in TPTX-A, P less than 0.05. Bone formation was reduced at each skeletal site in TPTX-A vs. TPTX-C, P less than 0.05 for all values, but histologic evidence of osteomalacia was not observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: In an attempt to clarify the mechanisms by which angiotensin II (AII) and arginine vasopressin (AVP) regulate mesangial cell function, we examined the membrane potential change of mesangial cells and found that cells contracted and membrane potential depolarized in response to AII and AVP. The depolarization was associated with decreased input resistance. Ca ionophore A23187 caused similar mesangial cell contraction and depolarization. The reversal potential (Vr) of the depolarization response to AII and AVP was -29 +/- 3 and -25 +/- 7 mV (mean +/- SD), respectively. Not only the Vr of the AII-induced depolarization but also Vr of the Ca ionophore-induced response was dependent upon the extracellular Cl- concentration. Further, AII and AVP caused cell contraction and membrane depolarization in Ca++-free medium containing 0.5 mM EGTA. These data suggest the presence of Ca++ -activated Cl- channels in the mesangial cells and that AII and AVP increase Cl- permeability via an elevation of [Ca++]i released from the intracellular organellae.

Abstract: TBT is a new technique that by use of a balloon catheter technique in a fashion similar to that of balloon angioplasty allows reestablishment of tubal patency in selected cases of tubal occlusion. The case presented here describes the first transcervical dilatation and recanalization of a proximally occluded fallopian tube in a patient with infertility.
