Black cohosh (Cimicifuga racemosa) and estrogen positively influence osteoporotic bone. Both substances may improve fracture healing in early osteoporosis as well. In 48 twelve-week-old ovariectomized or, respectively, sham-operated (SHAM) rats, a standardized metaphyseal tibia osteotomy with bridging T-plate fixation was performed. During the healing process of 35 days, rats received soy-free (SHAM, osteopenic C), estrogen-(E) or Cimicifuga racemosa-(CR) supplemented diets. After sacrifice, the callus formation was analyzed with regard to biomechanical quality, morphology, quantity, time course of new bone built and gene expression. CR induced a high rate of metaphyseal callus formation. The biomechanical properties and the amount of new callus formation indicated that fracture healing was still in progress. Therefore, gene expression of osteoblasts was comparatively high. Body weight and the trabecular structure were influenced little by CR. Estrogen improved the biomechanical properties of the callus. Resistance to microfracturing was significantly enhanced in the E group and even superior to SHAM. Remodeling of the callus formation had already begun. The trabecular network and the typical endosteal fracture healing were especially improved. Osteoporotic metaphyseal fracture healing was improved by estrogen more than by Cimicifuga racemosa. The process of fracture healing occurred nearly physiologically. The generation of callus formation was supported by Cimicifuga racemosa as well, but the five-week duration of application was too short for Cimicifuga racemosa to show its complete potential. Already-initiated Cimicifuga racemosa therapy for menopausal symptoms could be continued during fracture healing without hesitation."],["dc.description.sponsorship","DFG [STU 478/2-1]"],["dc.identifier.doi","10.1055/s-0029-1240798"],["dc.identifier.isi","000279668400002"],["dc.identifier.pmid","20104444"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19846"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Georg Thieme Verlag Kg"],["dc.relation.issn","0032-0943"],["dc.title","Effects of Black Cohosh (Cimicifuga racemosa) and Estrogen on Metaphyseal Fracture Healing in the Early Stage of Osteoporosis in Ovariectomized Rats"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Here we aimed to investigate the short-term effects of genistein and equol on the proximal femur of ovariectomized (OVX) rats. Forty-eight, 3-month-old female Sprague-Dawley rats were ovarectomized; after eight weeks the bilateral osteotomy and osteosynthesis (OS) of their tibiae was performed and the rats were randomly divided into the following four groups: OVX control group (C), treated with estradiol-17beta (E2) -benzoate (E; daily intake 0.086 mg/d per animal), genistein (GEN; daily intake 12.7 mg/d per animal) and equol (EQ; daily intake 4.65 mg/d per animal). At 5 weeks postoperatively (OS), the breaking test was performed on the trochanteric region of femur. Additionally, histomorphometric assessment, and trabecular and cortical bone microstructure analyses were performed. The relative gain of body weight (BW) in the EQ (24%) group was significantly (p < 0.05) lower than in the C (33%) and GEN (30%) groups.

A few publications addressing this topic can be found in the medical database, and there are no reports about these traumata in children. A total of 24 patients, average 16.6 years of age, suffering from nitric acid traumata were treated. Wound with I degrees burns received open therapy with panthenol-containing creams. Wound of II degrees and higher were initially treated by irrigation with sterile isotonic saline solution and then by covering with silver-sulphadiazine dressing. Treatment was changed on the second day to fluid-absorbent foam bandages for superficial wounds (up to IIa degrees depth) and occlusive, antiseptic moist bandages in combination with enzymatic substances for IIb degrees-III degrees burns. After the delayed demarcation, necrectomy and mesh-graft transplantation were performed. All wounds healed adequately. Chemical burn traumata with nitric acid lead to specific yellow- to brown-stained wounds with slower accumulation of eschar and slower demarcation compared with thermal burns. Remaining wound eschar induced no systemic inflammation reaction. After demarcation, skin transplantation can be performed on the wounds, as is commonly done. The distinguishing feature of nitric-acid-induced chemical burns is the difficulty in differentiation and classification of burn depth. An immediate lavage should be followed by silver sulphadiazine treatment. Thereafter, fluid-absorbent foam bandages or occlusive, antiseptic moist bandages should be used according to the burn depth. Slow demarcation caused a delay in performing surgical treatments. (C) 2009 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

There was an improvement of bone quality and density in both osteoporotic and control rats. This treatment may therefore be an attractive option for the treatment of osteoporosis. Aside from pharmacological treatment options, physical exercise is known to augment bone mass. In this study, the effects of whole-body vertical vibration (WBVV) on bone quality and density were evaluated using an osteoporotic rat model. Sixty female Sprague Dawley rats were ovariectomized (C) or sham (SHAM) operated at the age of 3 months. After 3 months, both groups were divided into two subgroups that received either WBVV at 90 Hz for 35 days or no treatment. After sacrificing the rats, we evaluated vertebral bone strength, histomorphometric parameters, and bone mineral density (BMD). Treatment with WBVV resulted in improved biomechanical properties. The yield load after WBVV was significantly enhanced. According to yield load and Young's modulus, the treated OVX rats reached the level of the untreated SHAM animals. In all measured histomorphometric parameters, WBVV significantly improved bone density. Treatment with WBVV demonstrated greater effects on the trabecular bone compared to the cortical bone. The ash-BMD index showed significant differences between treated and untreated rats. Using WBVV as a non-pharmacological supportive treatment option for osteoporosis demonstrated an enhancement of bone strength and bone mass. This procedure may be an attractive option for the treatment of osteoporosis."],["dc.identifier.doi","10.1007/s00198-009-0892-3"],["dc.identifier.isi","000271795200003"],["dc.identifier.pmid","19283328"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/4141"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/55844"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.publisher.place","London"],["dc.relation.issn","0937-941X"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Effects of low-magnitude, high-frequency mechanical stimulation in the rat osteopenia model"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
