Background: Various therapeutic options such as calcitonin have been suggested for patients with low bone density, despite uncertain efficacy in most patients. C-telopeptide of type I collagen (CTX) is a new bone marker used for the assessment of bone resorption. The aim of this study was to evaluate the therapeutic effects of nasal spray calcitonin in women with osteopenia via serum CTX and other laboratory tests. Methods: We conducted a self controlled clinical trial in 2009 on 105 women of menopausal age diagnosed in Baqiyatallah Hospital Clinic with osteopenia based on a bone mineral density score of 1.5 SD lower than peak bone mass. The patients were assigned to receive nasal spray calcitonin (200 IU/day), calcium (1000 mg/day) and Vit-D (400 IU/day) for 6 months. Serum CTX and other laboratory parameters were measured before and after the treatment. The data were analyzed by SPSS, version 17, using t-tests and a P

Statement of Problelem: Lichen plannus is a relatively common mucotanous disorder, due to accompanying"nburning sensation and pain in addition to its malignant transformation, has potential importance. On the other"nhand, B and C hepatitis are of the five most common death causes, resulting in significant disease spread"nproblems among dentists. As a result, the relationship between these two disorders has been recently"ninvestigated."nPurpose: The aim of the present study was to investigate the oral Lichen plannus prevalence among patients"nwith B and C hepatitis."nMaterial and Methods: In this case series study, 500 patients with B, C hepatitis, 3 04 female and 369 male"nwith the mean age of 39.09±13.13 (the youngest was 4 and the oldest was 72 years old), who referred to the"nhepatitis center of Shariati hospital, Transfusion organization and Hemophilia center, from August 2001 to"nAugust 2002, were evaluated. The information about all white lesions that couldn't be scraped was recorded"non a questionnaire for each patient. To analyze the data, t and Fisher tests were used."nResults: Two hundred and eighty nine patients were MBS Ag" 223 were HCVAb", 12 were positive for both"ntypes of hepatitis and 23 were cyrotic. From among these patients, 3 subjects were with oral Lichen plannus"n(0.6%), one belonged to HBS Ag1 group (0.35%), (P=0.38) and two patients belonged to HCV Ab' (0.9%),"n(P=0.44). These results showed no statistically significant relationship between Lichen plannus and B, C"nhepatitis. Two cyrotic patients from among 23 were with LP, which statistically was significant (P
