Abstract: In order to perform quantitative in vitro and clinical studies on the removal of Al by the combined therapy of DFO administration and HD, an HPLC system for measuring DFO was established and a leaky membrane with enhanced permeability to middle molecular substances was developed. The DFO infusion caused rises in plasma Al levels (regarded as indicating the elution of accumulated Al) in patients undergoing HD. Plasma levels increased most in long-term patients and those with bone pain. Examination of Al clearances demonstrated that this increased plasma Al content passed through HD membranes at levels of more than 80 micrograms/l, and that the leaky membrane was more effective for removal of Al as well as DFO than the conventional one. Although a 1:1 complex between DFO and Al in an aqueous solution was confirmed, the formation of Al-rich complexes in vivo was suggested. It is concluded that Al-DFO complex formed in vivo can be effectively removed across the leaky membrane.

Abstract: Percutaneous coronary laser thermal angioplasty was successfully performed before conventional balloon angioplasty in a 55 year old white man with a 90% left anterior descending artery stenotic lesion and angina at rest (Canadian Heart Association class IV). The lesion was reduced to 50% residual stenosis using a 1.7 mm laser-heated metallic capped fiber and two pulses of 8 W of argon laser energy, each delivered for 5 seconds. With subsequent balloon angioplasty, the lesion was further decreased to 10% residual stenosis. The entire procedure was well tolerated without chest pain or burning, vessel perforation or spasm, thrombus formation or embolization of debris. The patient was free of pain at 1 month follow-up. This case demonstrates the feasibility of safely performing percutaneous coronary laser thermal angioplasty. Additional studies are indicated to determine the clinical role and potential benefits of coronary laser thermal angioplasty in relation to the established procedures of bypass surgery and conventional balloon angioplasty.

Abstract: The purpose of this study was to determine whether the availability of PRL modulates the chloride concentration of human sweat. Full thickness human skin grafted into the back of immunoincompetent, nude, congenitally athymic mice heals in about 6 to 10 weeks and survives the life of the mice. Mice have no sweat glands in the back so this system provides a useful model for study of the physiology and pathology of human sweat glands. The graft can be induced to sweat and the sweat collected for analytical studies. Presumably normal skin obtained from 7 individuals undergoing reconstructive surgery was grafted successfully into 11 mice. On 49 occasions sweat was induced by pilocarpine iontophoresis and collected for 45 min. The chloride concentration was 12.9 +/- 6.7 meq/liter, values typical of normal human sweat. Nine mice bearing grafts were injected with rabbit anti-human PRL (hPRL). The chloride concentration of sweat obtained a day later was significantly elevated. The concentration generally increased after a second and sometimes a third injection of anti-PRL. The average maximum sweat chloride obtained was 61.9 +/- 8.25 meq/liter. Serum of rabbits that had not been exposed to hPRL was prepared and diluted in the same way as the anti-hPRL. The chloride concentration of sweat of 3 mice that received the preparation for several days remained unchanged at the low normal level. We conclude that depletion of PRL increases the concentration of chloride in human sweat.
