Cholecystolithiasis is a common disease, making cholecystectomy a commonly performed surgical procedure. The gross appearance of gallstones differs from case to case. To classify gallstones on the basis of their structure, we randomly collected gallstones from 100 (64 of them women) of 3,289 patients who underwent cholecystectomy at our hospital. The stones were grossly classified into five maj...

This study investigated the composition of common duct gall stones from 61 patients, aged 49-94. The stones were collected endoscopically with a dormia basket after endoscopic papillotomy. The cholesterol content was measured both by infrared spectroscopy (mean 29%, range 0-99%) and enzymatically (mean 23%, range 0-96%). The results of the two measurements showed good correlation (r2 = 0.92), i...

background and objective: nanoscopic life forms called nanobacteria or calcifying nanoparticles (cnp) are unconventional agents. these novel organisms are very small (0.1 to 0.5 microns) and possess unusual properties such as high resistance to heat and routine antimicrobial agents. nanobacteria are 100 times smaller than bacteria and protected by a shell of apatite, so they could be as candida...
