We have shown that Walker 256/S mammary carcinoma caused osteoporosis-like changes in young female rats, accompanied by low serum estradiol and hypercalciuria without changes in the serum levels of calcium, phosphorus, and parathyroid hormone-related peptide. In this study, we investigated the cause of bone loss after Walker 256/S inoculation into female 6-week-old Wistar Imamichi rats, focusin...

Introduction: Boron neutron capture therapy (BNCT) is a method of cancer treatment and potentially, two borono-L-phenylalanine (BPA) and sodium borocaptate (BSH) are used in BNCT as common boron carriers. Some previous studies have shown that the dose rate is directly related to boron concentration in the tissue. This study aimed to simulate the structure of boron carriers and brain tumor compo...

Pseudo papillary tumor of the pancreas, also called Frantz´s tumor, is a very rare disease; between 0.2 and 2.7% pancreatic carcinomas. Ethiology unknown; observed in young women. It´s tumors with low malignant potential, usually asymptomatic evolution by long time symptoms are due to regional compression: pain or abdominal mass. The possibility form around 15%. Anatomically, they most frequent...

background: many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. whether in vivo choline incorporation is related also to cell proliferation or not was my question. therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14c]-choline incorporation and in vivo [methyl-3h]- thymidine incorpora...

The mechanism of the enhanced vascular permeability and retention (EPR) effect seen in solid tumors was investigated with sarcoma 180 (S-180) in mice by using the bradykinin receptor antagonist D-Arg-[Hyp3,Thi5,D-Tic7,Oic8]bradykinin] (HOE 140), the nitric oxide (NO) scavenger 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (PTIO), and the cyclooxygenase (prostaglandin synthase) inhibito...

leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...

we report occurrence of a rare case of giant cell tumor (gct), in a 28-year old woman, arising from anterior arc of right 6 th rib during pregnancy. it progressed rapidly during breast-feeding period, mimicking malignant bone tumor at delayed presentation.

background and objectives:scrophularia variegata m. beib. (scrophulariaceae) is a medicinal plant, used for various inflammatory diseases in iranian traditional medicine. in the present study, we evaluated the immune modulation and antioxidant effects of the hydroalcoholic extract of s.  variegata. methods: the splenocytes were harvested from the spleen of balb/c mice and were cultured. the spl...
