RESUMO
OBJECTIVE: To compare the clinical effects of transurethral detaching resection (TUDRP) and plasmakinetic transurethral resection of the prostate (PKRP) for benign prostatic hyperplasia (BPH). METHODS: We collected by the single blind method the clinical data of 81 cases of BPH treated by PKRP (n=41) and TUDRP (n=40), and compared the two groups of patients in their age, preoperative prostate volume, weight of the resected gland, operation time, intraoperative bleeding, time of postoperative Foley's catheter retention, and pre- and post-operative IPSS. RESULTS: The post-operative IPSS was significantly higher in the PKRP than in the TUDRP group (9.95 +/- 1.54 vs. 8.70 +/- 1.13, t = 0.0029, P = 0.0059). CONCLUSION: TUDPR has a better clinical effect than PKRP in the treatment of BPH.

OBJECTIVE: To investigae the function of the glass colorant on the color of the machinable infiltrated ceramics(MIC). METHODS: Five kinds of glass with different colorant were infiltrated through the aluminous matrix by heating the components to 1 100 degrees C for 2 hours. The specimens surface was polished, and their thickness was 0.5 mm. RESULTS: The refractive index of the MIC infiltration glass was 1.59691 (587.6 nm, nd) . The most different parameter of the MIC color were L*, then a*, and b* had little difference . The parameters of the color space of MIC were: L*(64.55-71.46), a*(3.35-7.38), b*(10.00-12.41), Ca*b*(11.38-13.95), ha*b*(54.07-73.00). These were almost close to the color parameters of Vita In-ceram. CONCLUSION: This experiment proved that the glass colorant was changed the MIC color parameters, and the main function was on L*, then a*. The ceramic color was up to the requirement of clinic.
