Successful removal of staghorn and multiple renal calculi has been one of the mist difficult tasks that confront the urologists. The operative method for removal of the renal calculi was selected according to the size, number, location and anatomic features of the renal collecting system. We utilized the coagulum to improve the success of the stone removal for last five months. The coagulum material were mixed in a ratio of 5ml cryoprecipitate or 4% fibrinogen: 1ml 20 unit /ml human thrombin:0.2ml 10% calcium chloride. The results were as follows. 1. The patients were provided by 3 coagulum pyelolithotomy and 6 coagulum nephrolithotomy, of which utilized cryoprecipitate in 7 cases and 4% fibrinogen in 2 for the fibrinogen source. 2. The seven of nine cases(78.2%) were successfully removed without residual stone, but incompletely in two cases(22.2%). 3. Nondemonstrable stone of the preliminary film were removed additionally in one cases(11.1%). 4. As to the complication, meaningless wound infection and dehiscence was observed in only one case. On basis of our experiences, present here a histologic perspectives, methods, cases and its results, in dication and contraindication for coagulum pyelolithotomy and nephrolithotomy.

The vascular actions and mechanisms of taurine were investigated in the isolated human radial artery (RA). RA rings were suspended in isolated organ baths and tension was recorded isometrically. First, a precontraction was achieved by adding potassium chloride (KCl, 45 mM) or serotonin (5-hydroxytryptamine, 5-HT, 30 µM) to organ baths. When the precontractions were stable, taurine (20, 40, 80 mM) was added cumulatively. Antagonistic effect of taurine on calcium chloride (10 µM to 10 mM)-induced contractions was investigated. Taurine-induced relaxations were also tested in the presence of the K⁺ channel inhibitors tetraethylammonium (1 mM), glibenclamide (10 µM) and 4-aminopyridine (1 mM). Taurine did not affect the basal tone but inhibited the contraction induced by 5-HT and KCl. Calcium chloride-induced contractions were significantly inhibited in the presence of taurine (20, 40, 80 mM) (p<0.05). The relaxation to taurine was inhibited by tetraethylammonium (p<0.05). However, glibenclamide and 4-aminopyridine did not affect taurine-induced relaxations. Present experiments show that taurine inhibits 5-HT and KCl-induced contractions in RA, and suggest that large conductance Ca²⁺-activated K⁺ channels may be involved in taurine-induced relaxation of RA.

The present study is an attempt to delineate the effect of various salt administrations on the changes of blood pH and electrolytes, especially the nature of serum calcium, total and ionic, and serum magnesium. Thirty five male rabbits weighing 1.9 to 2. 5kg were used in this experiment. At the end of the three days diet adjustment period, the animals were divided into seven groups; Group I; Control, Group II; Ammonium chloride oral administration, Group III; Oral administration of sodium bicarbonate, Group IV; Potassium chloride intraveneous injection, Group V; Sodium chloride intravenous injection, Group VI; Calcium chloride intravenous injection, and Group VII; Magnesium chloride intravenous injection. The blood pH was determined by the method by Astrup and bicarbonate in serum by the method of Van Slyke and Neill. Sodium and potassium in serum were determined with an EEL flame photometer. Chloride was determined by the method of Schales and Schales and inorganic phosphorous by the method of Fiske and Subbarrow. Serum total calcium and magnesium were determined according to the method of chelometric titration with Eriochrome blue S.E. Serum ionic calcium was determined by the method of Yanagisawa. The results of this study are as follows: 1. The oral administration of ammonium chloride produced a significant decrease in blood pH. The serum concentrations of bicarbonate, magnesium and potassium were steadily decreased, but serum chloride, serum total and ionic calcium concentrations were increased through the experiment. 2. Sodium bicarbonate ingestion increased the concentration of bicarbonate, magnesium and serum ionic calcium markedly and serum ionic calcium slightly. The blood pH was significantly increased but serum chloride concentration was markedly reduced after ingestion of sodium bicarbonate However, serum potassium and inorganic phosphorus concentrations were decreased slightly. 3. The blood pH was dropped in the first two hours of intravenous injection of potassium chloride and tended to rise again significantly. the concentration of sodium and chloride in serum was increased markedly in two hours of injection but reduced after six hours to control level. Serum phosphorus, total and ionic calcium were reduced steadily, but serum concentration of magnesium, potassium and bicarbonate concentrations were slightly increased through the experiment 4. After sodium chloride was given, intravenously, there was a sustained increase in the concentration of serum sodium, potassium, phosphorus and bicarbonate but the blood pH was decreased in the first two hours and significantly elevated through the experiment. The serum concentration of chloride, magnesium, total and ionic calcium was decreased slightly. 5. B100d pH was slightly increased and the concentration of chloride was elevated sharply after injection of calcium chloride intravenously in the first two hours and come to control level in twenty-four hours. Serum sodium concentration was elevated steadily through the experiment. The concentration of total and ionic calcium in serum was elevated after injection but come to control level in twenty four hours of injection. Serum potassium and magnesium concentrations were decreased slightly in the first two hours and increased in four hours of injection. 6. Magnesium chloride intravenous injection produced a decrease in blood pH and serum concentration of bicarbonate in the first few hours and increase after 6 hours of injection. Serum magnesium, and inorganic phosphorus levels were increased after injection but the concentration of inorganic phosphrous was decreased markedly in twenty four hours of injection. Serum concentration of chloride, ionic calcium and potassium wag markedly reduced.

PURPOSE: Kidney stones (nephrolithiasis) are a widespread disease. Thus, blocking stone formation and finding new therapeutic methods is an important area of study. Diosmin (a major component of the bile) is known to have antioxidant as well as renoprotective effects. The present investigation aimed to evaluate the effect of diosmin on renal tissue protection in rats with ethylene glycol-induced nephrolithiasis. MATERIALS AND METHODS: The rats were randomly divided into three groups. Group one (control) did not receive any treatments. In groups two and three, nephrolithiasis was induced by 2.5% (V/V) ethylene glycol + 2.5% (W/V) ammonium chloride (2 mL/d). The second and the third groups received distilled water or diosmin (80 mg/kg/d) by gavage for 21 days. RESULTS: Stereological estimation of the renal structures revealed that the average volume of calcium oxalate (CaOx) in the nephrolithiasis+diosmin rats was -63% less than in the rats with untreated nephrolithiasis (p<0.01). The volume of the glomeruli, proximal and distal convoluted tubules, Henle's loop, collecting ducts, and vessels was reduced -32% to 58% after the induction of nephrolithiasis (p<0.001). In the nephrolithiasis+diosmin rats, on average, -70% to 96% of the glomeruli, proximal convoluted tubules, Henle's loop collecting ducts, and vessels remained intact (p<0.01). Degeneration of the cortical tissue was 5-fold that of the medulla. In the nephrolithiasis+diosmin rats, degeneration in the renal cortical tissue and medulla was reduced -70% and 44%, respectively, compared with that in the untreated nephrolithiasis group (p<0.01). CONCLUSIONS: Diosmin reduces CaOx deposition and the degeneration of glomeruli and tubules in a rat model of nephrolithiasis.

OBJECTIVES: This study was performed to evaluate the effect of blood contamination on the compressive strength (CS) of Root MTA (RMTA) modified with Calcium chloride (CaCl2) and Disodium hydrogen phosphate (Na2HPO4) as setting accelerators over time. MATERIALS AND METHODS: A total of 110 cylindrical specimens of RMTA were divided into 6 experimental groups as follows: Group1, RMTA; Group 2, RMTA modified with CaCl2 (RMTA-C); Group 3, RMTA modified with Na2HPO4 (RMTA-N); Group 4, RMTA contaminated with blood; Group 5, RMTA-C contaminated with blood; Group 6, RMTA-N contaminated with blood. The CS of specimens in all groups was evaluated after 3 hr, 24 hr, and 1 wk. In the modified groups (groups 2, 3, 5, and 6) the CS of five specimens per group was also evaluated after 1 hr. RESULTS: Blood contamination significantly reduced the CS of all materials at all time intervals (p < 0.05). After 3 hr, the CS of specimens in the RMTA groups (with and without blood contamination) was significantly lower than those in the RMTA-C and RMTA-N groups (p < 0.05). The CS values were not significantly different at the other time intervals. In all groups, the CS of specimens significantly increased over time (p < 0.05). CONCLUSIONS: Blood contamination decreased the CS of both original and accelerated RMTA.

BACKGROUND: Protamine sulfate (PS), used to neutralize the effect of heparin, is often associated with systemic hypotension. The present study was aimed to investigate the protective effects of CaCl2 on adverse hemodynamic reaction to PS. METHODS: Forty-six dogs of three groups were studied. Animals were randomly allocated to receive either; saline 10 ml (controls, n = 26), CaCl2 5 mg/kg (n = 10) or 10 mg/kg (n = 10), added to PS 3 mg/kg given intravenously 5 min after heparin (300 IU/kg, iv). Mean aortic pressure (MAP), mean pulmonary arterial pressure (MPAP), left ventricular end-diastolic pressure (LVEDP), LVdP/dtmax, and -LVdP/dtmin, and pulmonary artery (cardiac output) and left circumflex blood flow (LCX flow) were recorded up to 15 min after PS. RESULTS: PS caused significant reductions in MAP (-49%), cardiac index (CI, -66%), systemic vascular resistance index (SVRI, -22%), LVEDP (-67%), LVdP/dtmax (-36%), and LVdP/dtmin (-55%), but increased MPAP (39%) and PVRI (3.8 fold), which all increases and reductions peaked 1-3 min after PS injection in the control group. The addition of CaCl2 to PS significantly attenuated reductions of MAP (-35 and -26% in CaCl2 5 and 10 mg/kg treated dogs, respectively), CI (-34 and -37%), LVdP/dtmax (-14, -11% ), and -LVdP/dtmin (-34, -21%), and increases in PVRI (1.8 and 2.4 fold). However, both doses of CaCl2 increased MPAP (48, 82%), but not SVRI (-28, -21%) or LVEDP (-73, -75%). LCX flow increased similarly in all groups (75-137%). CaCl2 5 and 10 mg/kg iv increased plasma Ca2+ by 0.23 and 0.36 mM, respectively. CONCLUSIONS: These results suggest that the simultaneous administration of CaCl2 attenuates the adverse hemodynamic effects of PS, used to reverse heparin anticoagulation in the dog.

OBJECTIVE: To evaluate the effect of sonication, repeated freeze-thaw cycles, calcium salt solution and their combination on the content of related growth factors (GFs) released by platelet rich plasma (PRP). METHODS: Twenty PRPs from healthy blood donors were divided into 9 groups, including sonication group, freeze-thaw group, calcium gluconate group, calcium chloride group, sonication + calcium gluconate group, sonication + calcium chloride group, freeze-thaw + calcium gluconate group, freeze-thaw + calcium chloride group, and sonication + freeze-thaw group. After PRP activated by above 9 methods, the content of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and platelet-derived growth factor-BB (PDGF-BB) were detected by ELISA. RESULTS: The platelet concentration of the samples was (966.7±202.6)×10⁹/L. The content of TGF-β1 in sonication + freeze-thaw group was the highest, while the lowest was in freeze-thaw group. The content of VEGF in freeze-thaw + calcium chloride group was the highest, while the lowest was in calcium gluconate group. The content of PDGF-BB in sonication + freeze-thaw group was the highest, while the lowest was in calcium gluconate group. There was no significant differences in the three GFs between calcium gluconate group and calcium chloride group. CONCLUSION Among the 9 activated methods of PRP, there is no difference between two calcium salt solutions. And the combination of repeated freeze-thaw cycles and sonication may be the best treatment method to promote PRP to release GFs, while calcium gluconate is the weakest way.
