Description | D-Mannitol, a specific hydroxyl free radical scavenger, can reduce the developmental toxicity of hydroxyurea in rabbits; it has thermal properties and could be as a Phase Change Material (PCM) for latent heat storage system; it is a potential diagnostic marker for aspergillosis. D-mannitol has neuroprotectant effect in reducing the sensory neurological disturbances seen in ciguatera poisoning, it does not act purely as an osmotic agent to reduce swelling of nerves, but involves a more complex action dependent on the Na(v) channel subtype, possibly to alter or reduce toxin association. |

Animal Research | D-mannitol, a specific hydroxyl free radical scavenger, reduces the developmental toxicity of hydroxyurea in rabbits.[Pubmed: 8073363 ]Teratology. 1994 Apr;49(4):248-59.Hydroxyurea (HU) is a potent mammalian teratogen. Within 2-4 hours after maternal injection, HU causes 1) a rapid episode of embryonic cell death and 2) profound inhibition of embryonic DNA synthesis. A variety of antioxidants delays the onset of embryonic cell death and reduces the incidence of birth defects. Antioxidants do not block the inhibition of DNA synthesis, indicating that early embryonic cell death is not caused by inhibited DNA synthesis. We have suggested that some HU molecules may react within the embryo to produce H2O2 and subsequent free radicals, including the very reactive hydroxyl free radical. The free radicals could cause the early cell death; antioxidants are believed to terminate the aberrant free radical reactions resulting in lessened developmental toxicity.

Structure Identification | J. Appl. Sci., 2011, 11(16):3044-8.Thermal Analysis of D-mannitol for Use as Phase Change Material for Latent Heat Storage.[Reference: WebLink]The aim of this study was to investigate the thermal properties of D-Mannitol as a Phase Change Material (PCM) for latent heat storage system. Heat absorbed by D-Mannitol causes it to undergo a change from the solid to the liquid phase and this heat is stored as the latent heat of fusion. The stored energy can then be retrieved at a later time for various applications.

D-mannitol, a specific hydroxyl free radical scavenger, reduces the developmental toxicity of hydroxyurea in rabbits.[Pubmed:8073363]
Teratology. 1994 Apr;49(4):248-59.
Hydroxyurea (HU) is a potent mammalian teratogen. Within 2-4 hours after maternal injection, HU causes 1) a rapid episode of embryonic cell death and 2) profound inhibition of embryonic DNA synthesis. A variety of antioxidants delays the onset of embryonic cell death and reduces the incidence of birth defects. Antioxidants do not block the inhibition of DNA synthesis, indicating that early embryonic cell death is not caused by inhibited DNA synthesis. We have suggested that some HU molecules may react within the embryo to produce H2O2 and subsequent free radicals, including the very reactive hydroxyl free radical. The free radicals could cause the early cell death; antioxidants are believed to terminate the aberrant free radical reactions resulting in lessened developmental toxicity. To investigate whether hydroxyl free radicals cause the early episode of cell death, pregnant New Zealand white rabbits were injected subcutaneously on gestational day 12 with a teratogenic dose of HU (650 mg/kg) in the presence or absence of 550 mg/kg of D-Mannitol (Man), a specific scavenger of hydroxyl free radicals. Osmotic control rabbits received HU plus 550 mg/kg of xylose (Xyl, a nonactive aldose). At term, the teratologic effects of HU were ameliorated by Man as evidenced by decreased incidences of the expected limb malformations. Xyl exerted no demonstrable effect on HU teratogenesis. Histological examination of limb buds at 3-8 hours after maternal injection, showed that Man delayed the onset of HU-induced cell death by as much as 4 hours. Xyl had no effect. That Man acts within the embryo was shown by performing intracoelomic injections on alternate implantation sites with Man, Xyl, or saline followed by subcutaneous injection of the pregnant doe with HU. Embryos were harvested 3-8 hours later. Limb buds from saline- and Xyl-injected embryos exhibited the typical pattern of widespread HU-induced cell death at 3-4 hours, whereas Man-injected embryos did not exhibit cell death until 5-8 hours. These results are consistent with those reported for antioxidant-mediated amelioration of HU-induced developmental toxicity and with the hypothesis that hydroxyl free radicals are the proximate reactive species in HU-induced early embryonic cell death.
Inhaled mannitol for non-cystic fibrosis bronchiectasis: a randomised, controlled trial.[Pubmed:25246664]
Thorax. 2014 Dec;69(12):1073-9.
RATIONALE: Bronchiectasis is characterised by excessive production of mucus and pulmonary exacerbations. Inhaled osmotic agents may enhance mucociliary clearance, but few long-term clinical trials have been conducted. OBJECTIVES: To determine the impact of inhaled mannitol on exacerbation rates in patients with non-cystic fibrosis (CF) bronchiectasis. Secondary endpoints included time to first exacerbation, duration of exacerbations, antibiotic use for exacerbations and quality of life (QOL) (St George's Respiratory Questionnaire, SGRQ). METHODS: Patients with non-CF bronchiectasis and a history of chronic excess production of sputum and >/=2 pulmonary exacerbations in the previous 12 months were randomised (1:1) to 52 weeks treatment with inhaled mannitol 400 mg or low-dose mannitol control twice a day. Patients were 18-85 years of age, baseline FEV1 >/=40% and =85% predicted and a baseline SGRQ score >/=30. MAIN RESULTS: 461 patients (233 in the mannitol and 228 in the control arm) were treated. Baseline demographics were similar in the two arms. The exacerbation rate was not significantly reduced on mannitol (rate ratio 0.92, p=0.31). However, time to first exacerbation was increased on mannitol (HR 0.78, p=0.022). SGRQ score was improved on mannitol compared with low-dose mannitol control (-2.4 units, p=0.046). Adverse events were similar between groups. CONCLUSIONS: Mannitol 400 mg inhaled twice daily for 12 months in patients with clinically significant bronchiectasis did not significantly reduce exacerbation rates. There were statistically significant improvements in time to first exacerbation and QOL. Mannitol therapy was safe and well tolerated. TRIAL REGISTRATION NUMBER: NCT00669331.
Neuroprotectant effects of iso-osmolar D-mannitol to prevent Pacific ciguatoxin-1 induced alterations in neuronal excitability: a comparison with other osmotic agents and free radical scavengers.[Pubmed:15950247]
Neuropharmacology. 2005 Oct;49(5):669-86.
The basis for the neuroprotectant effect of D-Mannitol in reducing the sensory neurological disturbances seen in ciguatera poisoning, is unclear. Pacific ciguatoxin-1 (P-CTX-1), at a concentration 10 nM, caused a statistically significant swelling of rat sensory dorsal root ganglia (DRG) neurons that was reversed by hyperosmolar 50 mM D-Mannitol. However, using electron paramagnetic resonance (EPR) spectroscopy, it was found that P-CTX-1 failed to generate hydroxyl free radicals at concentrations of toxin that caused profound effects on neuronal excitability. Whole-cell patch-clamp recordings from DRG neurons revealed that both hyper- and iso-osmolar 50 mM D-Mannitol prevented the membrane depolarisation and repetitive firing of action potentials induced by P-CTX-1. In addition, both hyper- and iso-osmolar 50 mM D-Mannitol prevented the hyperpolarising shift in steady-state inactivation and the rise in leakage current through tetrodotoxin (TTX)-sensitive Na(v) channels, as well as the increased rate of recovery from inactivation of TTX-resistant Na(v) channels induced by P-CTX-1. D-Mannitol also reduced, but did not prevent, the inhibition of peak TTX-sensitive and TTX-resistant I(Na) amplitude by P-CTX-1. Additional experiments using hyper- and iso-osmolar D-sorbitol, hyperosmolar sucrose and the free radical scavenging agents Trolox and L-ascorbic acid showed that these agents, unlike D-Mannitol, failed to prevent the effects of P-CTX-1 on spike electrogenesis and Na(v) channel gating. These selective actions of D-Mannitol indicate that it does not act purely as an osmotic agent to reduce swelling of nerves, but involves a more complex action dependent on the Na(v) channel subtype, possibly to alter or reduce toxin association.
