This study was conducted to assess the effectiveness of a diet contained fresh anchovies and calcitriol supplementation for 6 weeks to prevent osteoporosis in ovariectomized rats. Fifteen Wistar rats aged 8 weeks were divided randomly into 3 groups (normal/K, ovariectomized/Ov, andovariectomized + calcitriol/OVD), 5 mice each. Group K and Ov rats were fed with fresh anchovies, while the OVD group was fed with freshanchovies + calcitriol. At the age of 15 weeks, all mice were done for euthanasia, then left femur was collected for immunohistochemistryexamination of tartrate resistant acid phosphatase5b (TRAP5b). The detection of (TRAP5b) was conducted using a monoclonal ant ibody antiTRAP5b, and detected using a streptavidin-biotin. The results showed that the metaphysis part of distal femur bone of mice group K, Ov, andOVD were positive TRAP5b stained with brown color on trabecular bone in bone marrow cavity and trabecular spiculum surface, but rats ingroup K and Ov had extensive bone marrow cavity and normal trabecular spiculum, whereas OVD group showed bone marrow cavity dilation,accumulation of adipocytes in the bone marrow cavity, and shorter the spiculum of trabeculae. It can be concluded that fresh anchovies diet andcalcitriol supplementation for 6 weeks are not effective in preventing osteoporosis in ovariectomized rats.Key words: calcitriol, femur, ovariohisterectomy

The objective of this research was to study the effectiveness of calcitriol and ethynil ethyl estradiol combinations to decrease osteoporosis and endometrial cancer risks in ovariectomized Wistar rats. Twenty five 8-week old female Wistar rats were randomly divided into five groups (normal controlled rats/NK, ovariectomized rats/OVK, ovariectomized rats + calcitriol supplementation/OVD, ovariectomized rats + ethynil ethyl estradiol supplementation/OVE, and ovariectomized rats + calcitriol + ethynil ethyl estradiol supplementation/OVDE). At the end of the study, all rats were weighed and euthanized with 10% ketamine and 2% xylazine. Uterus and left femur were taken and fixed in 10% formaldehyde solution for histopathological examination using hematoxylin and eosin stain. Uterus was weighed before the fixation. The results showed that the percentage of uterus weight in OVK was significantly decreased compared to NK. Meanwhile, the percentage of uterus weight in OVDE was significantly increased compared to OVK. Histopathological features of the uterus in OVK were atrophy, reduction of myometrial and endometrial layers thickness, and formation of cuboidal epithelium in the endometrial lumen. However, the thickness of myometrial and endometrial layers in OVDE were increased, and its endometrial lumen was lined with metaplastic and hyperplastic squamous cell. Histopathological features of distal femur epiphysis in OVK ras showed fewer trabecular spiculums and more adipocyte in the bone marrow compared to NK. However, OVDE had more trabecular bone spiculum and less adipocyte in the bone marrow compared to OVK. In conclusion, the combination of calcitriol and ethynil ethyl estradiol supplementation could reduce osteoporosis, but increased the endometrial cancer risk in ovariectomized Wistar rats.

Calcitriol supplementation in ovariectomized rats decreased bone resorption and increased bone formation, however, it depend on dose. The objective of the research was to study the response of femur bone in osteoporosis rats consuming calcitriol. Thirty female Wistar rats at 8 weeks of age were randomly divided into six groups (sham operated rats as normal control rats/group N and NK, ovariectomized control rats/group Ov and OvK, ovariectomized rats/group OvDand OvE) of five each. All rats were fed standard diet for 8 weeks. At 16 weeks  of age, group N and Ov  were euthanized, the right femur were taken for histopathological  examination. Group NK and OvK were fed a standard diet, group OvD was fed a standard diet +40ng calcitriol;  and group OvE was fed a standard diet+25µg ethynil ethyl estradiol. Treatments were done for six weeks. At the end of study, blood samples were taken from plexus orbitalis medialis for estrogen analysis. All rats were euthanized using ketamine10% and xylazine 2%. Right femur was taken for histopathological examination  using hematoxylin and eosin stain, and immunohistochemistry using monoclonal antibody anti TRAP5b which was detected with streptavidin-biotin.         The results showed that estradiol level of the rats in group OvD was not significantly different compared with the rats in OvK group, however, it was significanly lower compared to the rats in group OvE. Histopathologic figure of right distal femur metaphysis in group OvD was shown lesser adipocyte in the bone marrow and more trabecular bone speculum compared to group  OvK, however, there was more adipocyte in the bone marrow and lesser trabecular bone speculum compared to group OvE. Immunohistochemistry of distal femur metaphysis in group OvD and OvE were revealed tartrate resistant alkaline phosphatase 5b (TRAP5b) expression in trabecular bone, which was located in bone marrow space and trabecular speculum surface as well. Based on the results, it can be concluded that calcitriol 40ng/day supplementation in osteoporosis rats for 6 weeks decreased bone resorption and increased bone formation distal femur metaphysis.

Calcitriol supplementation in ovariectomized rats for 8 weeks reduce osteoporosis risk and safe for kidney depend a proper dose. The objective of the research was to study the efectivity of high dose calcitriol for osteoporosis prevention and safe for kidney  in ovariectomized Wistar rats. Fifteen female Wistar rats at 8 weeks of age were randomly divided into three  groups of five which were sham operated rats (KN), ovariectomized rats (KOV), and ovariectomized rats+calcitriol supplementation 200ng/day (OVD200). After 8 weeks of treatment, blood samples were taken from plexus orbitalis medialis for estrogen analysis. All rats were then euthanized, left tibia and left kidney were taken for histopathological examination using hematoxylin and eosin stain. Immunohistochemistry using anti TRAP5b monoclonal antibody was also done for left tibia by streptavidin-biotin.  The results showed that estradiol level of KOV was significantly decreased compared with KN (P<0.05), meanwhile, estradiol levels of OVD200 were not significantly different compared with KOV. Histopathologic figure of kidney in KOV was not different compared with KN. Glomerulus was surrounded by Bowman‘s capsule, proximal and distal convoluted tubulus were lined with typical cuboidal epithelium. Immunohistochemistry result of proximal tibial epiphysis in KOV were shown more tartrate resistant alkaline phosphatase 5b (TRAP5b) expression in trabecular bone, which was located in bone marrow space, and trabecular speculum surface as well. Meanwhile, proximal tibia epiphysis in OVD200 had less tartrate resistant alkaline phosphatase 5b (TRAP5b) expression compared with KOV. Histopathologic figure  of proximal tibia epiphysis in group OVD200 was shown more trabecular bone speculum and less adipocyte in the bone marrow compared with KOV. Histopathologic figure of kidney in OVD200 was showed glomerular  hypertrophy and atrophy, as well as protein deposits in proximal convoluted tubules epithelium.  In conclusion, calcitriol supplementation 200ng/day in ovariectomized rats for 8 weeks prevented osteoporosis risk but trigger urolithiasis. Key words :  : Calcitriol, osteoporosis, ovariectomized rats, urolithiasis

Adult bone marrow is a major site for hematopoiesis, and reduction of the bone marrow cavity induces hematopoiesis in extramarrow tissues. To investigate the rudimentary intramarrow and the compensatory extramarrow hematopoiesis, particularly B lymphopoiesis, we used 3 osteopetrotic mouse strains [op/op, mi/mi, and Fos(−/−)], which are severely deficient in functional osteoclasts and therefore form inadequate bone marrow cavities. We found that bone marrow in these osteopetrotic mice supports myelopoiesis but not B lymphopoiesis, although cells that have the potential to differentiate into B lineage cells are present in the bone marrow. Although B lymphopoiesis normally occurs both in the spleen and liver of newborn mice, compensatory B lymphopoiesis in adultop/op and mi/mi mice is observed only in the liver, while myelopoiesis is enhanced in both organs. Interestingly, mice lacking the Fos proto-oncogene exhibit B lymphopoiesis in the spleen as well as liver. The amounts of expression of steel factor, Flt3/Flk-2 ligand, and interleukin-7 in the bone marrow, spleen, or liver were not significantly affected in these osteopetrotic mutants. These findings suggest that the volume of the bone marrow cavity regulates B lymphopoiesis without affecting the production of certain hematopoietic growth factors. The splenic microenvironments that support both myelopoiesis and B lymphopoiesis in the neonatal stage are lost in adults and are not reactivated even in the osteopetrotic adults unless the Fos gene is disrupted.

Introduction: Despite a considerable amount of work on limb amputations, questions of the mechanism and conditions for the occurrence of pathological rearrangement in the bone stump and ways to prevent it remain unexplored. Aim: To study the nature of changes in the structural organization of bone stump after amputation. Material and methods: Nine series of experiments were conducted on 129 rabbits with amputation of the thigh and closure of the filing with fascia, muscles with varying degrees of tension and a bone plate. Duration of observation is 1, 3, and 6 months. The research method is histological with a filling of blood vessels with a mascara-gelatin mixture. Results and discussion: Tight closure of the bone marrow cavity and uniform muscle tension during plastic surgery in the I–III series of experiments make it possible to obtain cylindrical stumps with the formation of a bone closure plate and the completion of the reparative process. In the majority of observations of the IV–IX series, significant violations of the structural organization of the bone occurred in the form of conical, club-shaped, swollen stumps, creeping fractures. Conclusions: The rapid completion of the reparative process and the normalization of intraosseous circulation with a locking bone plate, while maintaining normal bone marrow tissue, is possible only with a dense closure of the filing. The lack of tight closure of the bone marrow canal and uneven muscle tension cause a violation of regeneration with changes in the structural organization of the bone. These changes are manifested by a thickening of the bone diameter, axis curvature, creeping fractures.
