Purpose: Based on our previous data on the histamine radioprotective effect on small intestine, in the present work we aimed to determine whether histamine is able to protect bone marrow cells against ionising radiation damage. Materials and methods: 56 mice and 40 rats were divided into four groups. Histamine and histamine-irradiated groups received a daily subcutaneous histamine injection (0.1 mg/kg) starting 24 h before irradiation. Irradiated groups received a single dose on whole-body… 
Radioprotective potential of histamine on rat small intestine and uterus
TLDR
The obtained evidences indicate that histamine is a potential candidate as a safe radio-protective agent that might increase the therapeutic index of radiotherapy for intra-abdominal and pelvic cancers, however, its efficacy needs to be carefully investigated in prospective clinical trials.
Protection of Radiation-Induced Damage to the Hematopoietic System, Small Intestine and Salivary Glands in Rats by JNJ7777120 Compound, a Histamine H4 Ligand
TLDR
JNJ7777120 exhibits radioprotective effects against radiation-induced cytotoxic and genotoxic damages in small intestine, SMG and hematopoietic tissues and, thus, could be of clinical value for patients undergoing radiotherapy.
Histamine prevents functional and morphological alterations of submandibular glands induced by ionising radiation
TLDR
Histamine prevents morphological and functional radiation-induced damage on SMG, representing a potential radioprotector for treatment of patients undergoing radiotherapy for head and neck malignancies.
Oral Administration of Vitamin C, Cimetidine and Famotidine on Micronuclei Induced by Low Dose Radiation in Mouse Bone Marrow Cells
TLDR
Oral administration of Famotidine, vitamin C and Cimetidine demonstrate reliable and similar radioprotective effects and the protective effect of single use of these drugs was similar to the combination form.
Selective cytoprotective effect of histamine on doxorubicin-induced hepatic and cardiac toxicity in animal models
TLDR
Preclinical evidence is provided indicating that histamine could be a promising candidate as a selective cytoprotective agent for the treatment of Dox-induced cardiac and hepatic toxicity, and encourage the translation to clinical practice.
Pharmaceutical drugs supporting regeneration of small-intestinal mucosa severely damaged by ionizing radiation in mice
TLDR
Several current pharmaceutical drugs, for which the clinical trials have already been completed, are included in tests on mice that had undergone severe mucosal damage by radiation, and can be used to construct therapeutic programs and applied in various experimental studies to control the regeneration of damaged mucosa.

TLDR
Reduction in hematopoietic aplasia and chromosomal aberrations, besides, early recovery in bone marrow and spleen of G-002M pretreated mice, could be attributed to its free radical scavenging, DNA protecting and apoptotic proteins modulating ability against radiation.
Enhancement of ionizing radiation response by histamine in vitro and in vivo in human breast cancer
TLDR
Investigating the combinatorial effect of histamine or its receptor ligands and gamma radiation in vitro on the radiobiological response of 2 breast cancer cell lines concluded that histamine increased radiation response of breast cancer cells, suggesting that it could be used as a potential adjuvant to enhance the efficacy of radiotherapy.
PANC-1 cells proliferative response to ionizing radiation is related to GSK-3β phosphorylation
TLDR
Although histamine diminished catalase activity in nonirradiated cells, it only partially hindered the increase observed in irradiated cells and could not modify radiosensitivity, and an increment in reactive oxygen species levels produced an augmentation in GSK-3β phosphorylation and suppressed cell proliferation.

Mechanisms underlying the radioprotective effect of histamine on small intestine
TLDR
Histamine prevents radiation-induced toxicity by increasing proliferation of damaged intestinal mucosa and suppressing apoptosis that was associated with an increase in SOD and Catalase levels.

TLDR
It can be concluded that H2-receptor antagonists reduced the clastogenic effects of radiation with a dose reduction factor (DRF) of 1.5-2 in vivo and in vitro.
Effects of macrophage depletion on the induction of histidine decarboxylase by lipopolysaccharide, interleukin 1 and tumour necrosis factor
TLDR
The results indicate that the major cells in which HDC activity is induced in response to LPS, IL‐1 and TNF are not circulating granulocytes, circulating monocytes, T cells derived from thymus, mast cells or phagocytic macrophages.

Radioprotectants: Current Status and New Directions
TLDR
The objective of developing newer cytoprotective therapies is to improve the therapeutic ratio by reducing the acute and chronic toxicities associated with more intensive and more effective anticancer therapies.
Radioprotection by Antioxidants a
TLDR
Naturally occurring antioxidants, such as vitamin E and selenium, are less effective radioprotectors than synthetic thiols but may provide a longer window of protection against lethality and other effects of low dose, low‐dose rate exposures.

Post‐consolidation Immunotherapy with Histamine Dihydrochloride and Interleukin‐2 in AML
TLDR
The preclinical background to the use of HDC/IL‐2 in AML is accounted for along with a review of clinical results to demonstrate that post‐consolidation treatment with the combination of histamine dihydrochloride and IL‐2 significantly prevents relapse inAML patients.
