  • The article is devoted to the study of the density dependence of the horns tissue on the species and the age of the representatives of the deer family. In scientific literature this problem was covered partially. Basic physical parameters (mass, volume, and density) of horns from red deer (Cervus elaphus), fallow deer (Dama dama), European (Capreolus capreolus) and Siberian roe deer (Capreolus pygargus) were estimated. The present study was designed to analyze the results for making identification of species and age of the animal possible.

  • Osteoporosis is characterized by bone loss and mobidity with osteoporotic fracture. This study was performed to evaluate the effect of on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporsis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with DBE, extract of Dioscorea batatas, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of DBE. Osteoporetic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns. DBE showed inhibitory effect on bone loss in osteoporetic condition, and reduced the increase of ALP activity and osteocalcin level in serum, and reduced the increase of OH-proline level in urine. But, DBE had no effect on cell proliferation and ALP activity in rat calvarial cell culture.

  • This study was performed to evaluate the effect of HCB on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporosis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with HCB, extract of Houyttnia cordata, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of HCB. Osteoporotic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns.
