Hydrochlorothiazide prevents bone loss in castrated male mice
13rd Department of Internal Medicine, Charles University, Faculty of Medicine, Prague, Czech Republic.
Abstract:
The castration of male mice results in osteopenia which is a suitable model for evaluating the effect of thiazides on bone. The bones of castrated mice were characterized by a decrease of ash weight, bone density and calcium and phosphate bone content. When such castrated mice were treated with high dose of hydrochlorothiazide (2 mg/day/mouse) the changes in bone density and bone mineral concentration resulting from the castration were prevented. Our data indicate a beneficial effect of long-term thiazide administration on bone mineral content in male mice, which is dose dependent.
Insights
Castration in male mice causes bone loss, but hydrochlorothiazide treatment prevented these changes. Thiazide administration shows a dose-dependent, beneficial effect on bone mineral content in this osteopenia model.
Area of Science:
- Endocrinology
- Bone Biology
- Pharmacology
Background:
- Castration in male mice induces osteopenia, a condition characterized by reduced bone mass and density.
- This model is valuable for investigating interventions targeting bone loss.
Purpose of the Study:
- To evaluate the effect of hydrochlorothiazide on bone density and mineral content in a mouse model of post-castration osteopenia.
- To determine if thiazide administration can prevent or mitigate bone loss induced by castration.
Main Methods:
- Male mice were castrated to induce osteopenia.
- Castrated mice were treated with varying doses of hydrochlorothiazide.
- Bone ash weight, bone density, and calcium and phosphate content were measured.
Main Results:
- Castration led to significant decreases in bone ash weight, density, and mineral content.
- High-dose hydrochlorothiazide treatment (2 mg/day/mouse) prevented the castration-induced decline in bone density and mineral concentration.
- The protective effect of thiazides on bone mineral content was found to be dose-dependent.
Conclusions:
- Long-term administration of hydrochlorothiazide demonstrates a beneficial effect on bone mineral content in male mice with post-castration osteopenia.
- Thiazide treatment can prevent bone loss associated with castration in this animal model.
- The study highlights the potential of thiazides as a therapeutic agent for preventing bone loss, with efficacy related to dosage.
