Glyphosate (N-(phosphonomethyl) glycine,C3H8NO5P), a herbicide, used to control unwanted annual and perennial plants all over the world. Nevertheless, occupational and environmental exposure to pesticides can pose a threat to nontarget species including human beings. Therefore, in the present study, genotoxic effects of the herbicide glyphosate were analyzed by measuring chromosomal aberrations (CAs) and micronuclei (MN) in bone marrow cells of Swiss albino mice. A single dose of glyphosate was given intraperitoneally (i.p) to the animals at a concentration of 25 and 50 mg/kg b.wt. Animals of positive control group were injectedi.p. benzo(a)pyrene (100 mg/kg b.wt., once only), whereas, animals of control (vehicle) group were injectedi.p. dimethyl sulfoxide (0.2mL). Animals from all the groups were sacrificed at sampling times of 24, 48, and 72 hours and their bone marrow was analyzed for cytogenetic and chromosomal damage. Glyphosate treatment significantly increases CAs and MN induction at both treatments and time compared with the vehicle control (P<.05). The cytotoxic effects of glyphosate were also evident, as observed by significant decrease in mitotic index (MI). The present results indicate that glyphosate is clastogenic and cytotoxic to mouse bone marrow.

Genotoxic effects of crude bacteriocin extracted from Citrobacter freundii were detected on albino mice bone marrow cells in vivo, using micronucleus (MN) and comet assay. The mice were administered intraperitoneally with 37.5, 75, 150 and 300 mg/kg of the extract for 24 hours. C. freundii was isolated from patients suffering from urinary tract infections (UTI). The bacteriocin producing isolates were determined using cup assayand the most efficient bacteriocin producers were selected. Bacteriocin was extracted from the efficient isolates via the induction with Mitomycin-C (2 mg/ml). Bacteriocin activity (320 U/ml) was determined by well diffusion method, while the protein concentration (2900µg/ml) was estimated by Lowery method. The results showed an acute dose-dependent toxic effect of the crude bacteriocin ; The higher doses (150 and 300 mg/kg) caused a significant increase (P≤0.05) in the micronuclei frequency in the bone marrow cells (4.62 and 5.37%, respectively (. Furthermore, DNA damage   increased significantly (P≤0.05) and proportionally to higher bacteriocin doses (75, 150 and 300 mg/kg), as demonstrated by increased values of  tail length  (145.18, 267.73 and 295.08 %,( %DNA in tail (8.05, 13.87 and 14.31 %(, and olive tail moment (13.25, 22.72 and 25.85 % , respectively.

Изучена антимутагенная активность противолучевых препаратов разного механизма действия: беталейкина, флагеллина, индралина и рибоксина в краткосрочных и хроническом экспериментах на мышах in vivo. Все препараты проявили антимутагенные свойства в клетках костного мозга, а также гепатопротекторное действие. Наибольший эффект при используемых условиях эксперимента отмечен для беталейкина и нового противолучевого препарата флагеллина. The antimutagenic activity of anti-radiation drugs betaleukin, flagellin, indraline and riboxin with different mechanisms of action was studied in short-term and chronic experiments in mice in vivo. All drugs showed antimutagenic properties in bone marrow cells, as well as hepatoprotective effect. The greatest effect under the used experimental conditions was noted for betaleukin and the new anti-radiation drug flagellin.

In this study, the cytotoxic potential of fluoride and endosulfan in combination was investigated in Swiss albino mice bone marrow cells using the chromosomal aberration (CA) and micronucleus (MN) test systems. Fluoride (25.1 mg kg−1 body weight [bw] in water) and endosulfan (1.8 mg kg−1 bw by oral intubation) were administered orally alone and in combination (fluoride 25.1 mg kg−1 bw + endosulfan 1.8 mg kg−1 bw) to male Swiss albino mice daily for 30 days. A significant ( p < 0.01) increase in micronuclei (MNs) induction and decreased ratio ( p < 0.01) of polychromatic to normonochromatic erythrocytes (indicators of cytotoxicity) were observed compared with saline controls when animals were given the combination of fluoride and endosulfan. A significant ( p < 0.01) increase in MNs induction and no change in the polychromatic erythrocytes to erythrocyte ratio were also observed when endosulfan was given alone. CAs such as gaps, breaks, fragments, rings, exchanges, and polyploidy were recorded in the bone marrow cells. The mean percent frequency of CAs was increased ( p < 0.01) in all the treated groups compared with the control saline group. In the combination group (F + E), the percent frequencies of CAs were significantly higher (13.875%) compared with those in the individual treatment groups of fluoride (4.375%) and endosulfan (6.25%). The mitotic index was calculated as percentage of dividing cells. A significant ( p < 0.01) decrease in mitotic index was observed in all treated groups compared with controls. In the combination group (F + E), mitotic index was significantly less than ( p < 0.01; 4.1 ± 0.49) the saline control (10.8 ± 0.98). These results indicated that repeated intake of endosulfan through various sources in fluoride affected areas resulted in increased cytotoxic effects. The greater effect in the combination group indicated additive interaction of fluoride and endosulfan in inducing cytotoxicity in Swiss albino mice.

Extract ofAdhatoda vasica(L) Nees leaves has been used for treatment of various diseases and disorders in Ayurved and Unani medicine. Modulatory effect of ethanolic extract ofA. vasica(L) Nees against radiation-induced changes in terms of histological alterations in testis, reduced glutathione (GSH), lipid peroxidation (LPO), acid and alkaline phosphatases levels, and chromosomal alterations in Swiss albino mice was studied at various post-irradiation intervals between 1 and 30 days. Mice exposed to 8 Gy radiation showed radiation-induced sickness including marked changes in histology of testis and chromosomal aberrations in bone marrow cells with 100% mortality within 22 days. When ethanolic leaf extract ofA. vasicawas given orally at a dose of 800 mg kg−1body weight per mouse for 15 consecutive days and then exposed to radiation, death ofAdhatoda-pretreated irradiated mice was reduced to 70% at 30 days. The radiation dose reduction factor was 1.43. There was significantly lesser degree of damage to testis tissue architecture and various cell populations including spermatogonia, spermatids and Leydig cells. Correspondingly, a significant decrease in the LPO and an increase in the GSH levels were observed in testis and liver ofAdhatoda-pretreated irradiated mice. Similarly, a significant decrease in level of acid phosphatase and increase in level of alkaline phosphatase were observed.Adhatodapretreatment significantly prevented radiation-induced chromosomal damage in bone marrow cells. The study suggests thatAdhatodaplant extract has significant radioprotective effects on testis that warrants further mechanistic studies aimed at identifying the role of major ingredients in the extract.
