Irradiation injuries anti-agents refer to drugs that can inhibit the initial stage of radiation injuries, or reduce the development of radiation injuries and promote the recovery of injuries when used early after irradiation exposure. According to the mechanism of action and the time of intervention, the irradiation injuries anti-agents are divided into four categories: radioprotectors, radiomitigators, radiation therapeutics for external radiation exposure, and anti-agents for internalized radionuclides. In this paper, the research progress of irradiation injuries anti-agents in recent years is reviewed.

Myelodysplastic syndrome (MDS) is one of the most prevalent haematological malignancies originating from haemopoietic stem/progenitor cells. MDS characterized by morbid haematopoiesis of bone marrow and peripheral blood cell reduction and mainly occurs in the elders. The dangerous factors of MDS include chemotherapy, radiotherapy, benzene, other organic solvent, immune depressants and so on. Following the recent progress of medical sciences, a large number of new regimens of chemotherapy, radiotherapy and immune therapy against carcinomas generate and lead the development of therapeutics for malignancies. It is worried that the incidence of MDS still increases year by year and the patient age becomes younger. Although many agents are used to MDS, curative effect is not as good as expect. Amifostine, a kind of pancytoprotector also used in treatment of MDS. This review summarizes the mechanism of amifostine in MDS therapy which possesses a challenge binding with the current related investigations.

Review of the current literature available on Rasayanas indicates that anti-oxidant and immunomodulation are the most studied activities of the Rasayana drugs. Querying in Pubmed database on Rasayanas reveals that single plants as well as poly herbal formulations have been researched on. This article reviews the basics of Rasayana therapy and the published research on different Rasayana drugs for specific health conditions. It also provides the possible directions for future research.

This article explores the most recent evidence-based information on ethnomedicinal, phytochemical and pharmacological understanding of Hygrophila auriculata for the treatment of various diseases and health conditions. Various ethnomedicinal writings suggest the use of the plant or its parts for the treatment of jaundice, oedema, gastrointestinal ailments, diarrhoea, dysentery, urinogenital disorder, gall stones, urinary calculi, kidney stone, leucorrhoea, rheumatism, tuberculosis, anaemia, body pain, constipation, skin disease, and as an aphrodisiac. The plant has been reported to contain flavonoids (apigenin, luteolin, ellagic acid, gallic acid and quercetin), alkaloids (asteracanthine and asteracanthicine), triterpenes (lupeol, lupenone, hentricontane and betulin), sterols (stigmasterol and asterol), minerals, amino acids, fatty acids, aliphatic esters and essential oils. Extracts and bioactive compounds from the plant have been found to possess antimicrobial, anthelmintic, antitermite, nephroprotective, hepatoprotective, central nervous system protective, antitumour, antidiabetic, anticataract, antioxidant, haematopoietic, diuretic, antinociceptive, anti-inflammatory, antipyretic, antimotility, aphrodisiac, neuroprotection, anti-endotoxin and anti-urolithiatic activities. For this paper, we reviewed patents, clinical studies, analytical studies and marketed formulations from the earliest found examples from 1887 to the end of 2017.

The pharmacodynamic active parts of protecting liver of Peristrope japonica (thunb.) Bremek were identified. Rat acute liver injury model was induced by D-galactosamine (D-GlaN). The active parts were identified on the whole extraction and 4 fractions. The results showed that the pharmacodynamic active parts of Peristrope japonica were the n-BuOH fraction.

OBJECTIVETo study the effects of Liuweidihuang pills on pancreatic islet structure in OLETF (Otsuka Long-Evans Tokushima Fatty) rats.

METHODSForty male OLETF rats were divided randomly into Liuweidihuang pills group (Liuwei group) and control group (n=20). Ten male LETO rats were used as normal control group (LETO group). The rats in Liuwei group were given Liuweidihuang pills at the daily dose of 2.4 mg/kg intragastrically since the age of 8 weeks. Blood glucose was determined by OGTT. The rats were sacrificed at 8, 32 and 40 weeks and the pancreatic tissue was isolated to examine the morphological changes of the pancreas by HE staining and Masson trichrome staining.

RESULTSAs the age of the rats increased, the pancreatic islets in the control group gradually showed fibrosis and islet atrophy, which were not found in Liuwei group. Masson staining visualized no fibrosis in Liuwei group. No significant pathological change occurred in the pancreatic islet of LETO rats. The rats in Liuwei group developed diabetes since 30 weeks of age and the incidence was 28.6% at 40 weeks, significantly lower than that in the control group (P<0.01).

CONCLUSIONLiuweidihuang pills can prevent degeneration of the pancreatic islets in spontaneous OLETF rats.
