Spirogyra spp. (tao) is freshwater green algae which are consumed as an uncooked food especially in the north of Thailand. Aquatic plants especially algae are easily contaminated by pesticide residues from soil and water. Paraquat (1,1β-dimethyl, 4,4β-bipyridinium dichloride; PQ), a widely used herbicide among Thai farmers, is toxic, mutagenic, and carcinogenic to mammals through ingestion, inhalation and skin contact. This study aims to determine the concentrations of paraquat contaminated in Spirogyra spp. (tao) and health risk assessment on the consumption of Spirogyra spp. (tao) in Chiang Mai province, Thailand. The levels of paraquat were analyzed by using a simple, sensitive, and reliable method which was high performance liquid chromatography (HPLC). Seven samples were collected from the different districts. The levels of paraquat contamination were 5.07±0.00 to 12.69±0.10 mg/kg. The results showed that the concentrations of paraquat in all samples were lower than the standard level of the European Commission Regulation. Risk assessment of paraquat found that the hazard quotient was in the range of 0.18-0.46. It indicated that the consumption of Spirogyra spp. (tao) was expected to have no adverse health effects. However, the consumption of Spirogyra spp. (tao) should be a concern in terms of chronic exposure to toxic herbicide contaminated in the environment.

Tinospora cordifolia is an herbaceous vine that belongs to the Menispermaceae family, a succulent woody shrub genus, native to the tropical Indian sub-continent, and it is known for its common names: “Guduchi”, “giloy”, “amrita”, “gurjo”, and “heart-leaved moonseed”. The recent recognition and biological role of active components in disease management in the plant have contributed to an active interest in the plant worldwide. Extracts of T. cordifolia are widely used as antispasmodic, anti-microbial, antiperiodic, immunomodulatory, anti-inflammatory, anti-arthritic, anti-allergic, endocrine disorders like anti-diabetic, hypolipidaemic, etc. in various herbal formulations to treat different diseases. It helps reduce the resistance to insulin and stress, revitalises all the tissues of the body, and spontaneously promotes metabolism. However, this adaptogenic ability is also under-explored. Stress and ageing disorders need to be treated independently. The current review paper mainly focused on stress, depression, and the anti-stress properties (adaptogen) of T. cordifolia. Depression and stress, along with disrupted metabolic and reproductive properties, are high-risk factors in polycystic ovarian syndrome patients. Further studies are needed to focus on adaptogenic activity to relieve certain endocrine disorders that occur due to stress, often ovarian cysts, female menstrual irregularities, and hormonal imbalance.

Brominated Flame Retardants (BFRs) are being utilized to reduce the flammability of plastics, textiles, and electronics. They differ in their chemical properties and structures, and it is conventional that these distinctions alter their biological interactions as well as toxicity. Tetra-Bromo-Bis-Phenol A (TBBPA) is a pervasive environmental contaminant that is seen in both abiotic and biotic matrices. This review discusses the occurrence, distribution, and fate of TBBPA from source to the environment. Recent studies have raised worry over the potentially harmful implications of TBBPA exposure in humans and wildlife, prompting its characterization under group 2A “Probably carcinogenic to humans” by the International Agency for Research on Cancer. Worldwide there are no present confinements on its production and usage. On the other hand, very little information is accessible with respect to its toxicity to humans and aquatic animals. More research is required to characterize human exposure to TBBPA in and around production facilities, as well as in e-waste recycling regions. So as to safeguard the environment and human health, detailed investigations are urgently needed, especially on tracking the exposure pathways which may affect the workers and local residents around the exposure sites.

More than a hundred million people from almost twenty-five countries, including India, are affected by fluorosis. An assessment of fluoride in water, a prospective study of dental fluorosis and the role of calcium in preventing or ameliorating dental fluorosis through a long-term community study in endemic high fluoride area in Northern India was done. Water survey from different areas was done to identify high fluoride area in Unnao district of Uttar Pradesh, India. House to house survey of a population of almost 5000 people was done. Biochemical tests were performed in 50 dental fluorotic and 50 non-fluorotic randomized subjects. Clinical and biochemical status was recorded after six months of calcium supplementation. Our results have shown that 28.64% population had dental fluorosis (total fluorosis: 43%), the highest in 13-15 years age group. After six months of calcium supplementation, 44% of cases showed reversal of dental fluorosis, whereas in 40% of them disease did not progress further. An increase in serum calcium and a significant decrease in urinary fluoride was observed post supplementation. In this first large-scale prospective community study of its kind, it is demonstrated that long-term administration of calcium can reverse dental fluorosis especially in children with early grades of fluorosis. Calcium may protect tooth against damage from high fluoride intake and reduces dental fluorosis. With the increase in the prevalence of dental fluorosis, calcium can prove a cheap and effective method for the prevention and treatment of dental fluorosis.

Rheumatoid Arthritis (RA) is an autoimmune inflammatory disease. Accumulating evidences show that natural products use for RA treatment is gaining importance in the medical world due to negative effects associated with orthodox medicines. This study investigated the anti-inflammatory and antioxidant potency of Stem Bark of Cleistopholis Patens (SBCP) on Chicken Type II collagen in Complete Freund’s Adjuvant (CFA) induced RA in rats. Experimental rats were divided into nine groups (n= 15). RA was established in the rats by a single intradermal injection of 0.1ml Chicken Type II collagen in CFA through the left hind paw. The serum concentrations of Interinterleukin- 1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-κ), malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD) and catalase (CAT) were evaluated. Unlike the untreated arthritic group, the test groups (4-9) orally administered with graded doses (400, 600 and 800 mg/kg) of SBCP extracts for twenty-one days showed significant reduction (P < 0.05) in concentrations of IL-1β, IL-6, TNF-κ, MDA and NO while the activities of SOD and CAT increased significantly (P < 0.05) when compared to the negative control. The anti-inflammatory and antioxidative effects of SBCP extracts were comparable to that of the reference drug, indomethacin. This study indicates that SBCP ethanol and aqueous extracts could suppress proinflammatory cytokines and reduce oxidative stress in rheumatoid arthritic rats.

Prolonged ingestion of fluoride leads to the pathogenesis known as fluorosis. Fluoride exposure leads to neuro degenerative changes such as reduction in the neuronal cell size and number. Exposure to fluoride showed neurodegenerative changes like shrunken neurons, increased in folding of the nuclear membrane, mitochondrial alterations, and dilated rough endoplasmic reticulum cisternae and clusters of vesicles near the Golgi bodies. Present study is to explore the histomorphometric changes of the hippocampus of fluoride induced brain and treated with Ginkgo biloba Extract (GBE). Thirty number (30) adult male Wistar rats were randomly separated into 5 Groups (n=6). Group1 (Control) supplemented with water, 2 to 5 Groups were supplemented with 100ppm of sodium fluoride for 30 days, while the Groups 3, 4, and 5 were Ginkgo biloba extract treated at 50mg/ kg, 100mg/kg and 200mg/kg body weight for 15 days, after sodium fluoride treatment, results showed that, 200mg/kg GBE provided effective and complete protection against fluoride toxicity. From the present study concluded that 50, 100 and 200 mg/kg GBE was significantly attenuated the fluoride induced toxicity in a dose depending manner. Present histomorphometrical study showed delayed neuronal death in the CA1 and CA3 regions of hippocampus of fluoride group that was significantly attenuated by GBE (50,100 and 200 mg/kg) in a dose dependant manner.

In the present investigation, the toxicity of imidacloprid was tested on the embryos (fertilized eggs) and hatchlings of Cyprinus carpio in terms of mortality (%), hatching success (%) and abnormal/malformed hatchling along with their growth performance in toxicant medium. Reported data from acute toxicity tests of imidacloprid was statistically analyzed by Probit Analysis Method and 48 h (hour) LC50 was reported as 78 ppm for embryos of C. carpio. Three sublethal doses of imidacloprid i.e., 7.8 ppm (T1), 15.6 ppm (T2) and 23.4 ppm (T2), were selected for further experimentation along with control. The findings revealed that mortality of exposed eggs (%) was significantly (p<0.05) increased in dose dependent manner as a result hatching rate (%) was decreased as compared to control. Similarly, per cent of abnormal hatchling was also increased significantly (p<0.05) with increase in pesticide concentration. Various types of abnormalities has been reported in different body regions such as whole length curved body, stunted growth, hatchling with single eye, malformed head, flexure in the tail and deformed yolk sac etc. Growth rate was observed as length gain in centimeter (cm), weight gain in grams (g) and growth per cent gain in body weight of hatchling, which was also found to be declined significantly (p<0.05) with increase in pesticide concentration. The findings of the present investigation suggest that imidacloprid has significant effect on the early developmental stages, induces malformations and also decline the growth rate of hatchlings.

Zanthoxylum acanthopodium DC. is widely used in traditional plant-based medical practices in India, with different parts of this plant used to treat a variety of ailments. Though this has been a time-tested practice, the side effects and other implications that the plant may have should not be overlooked. This study evaluated the toxicity of the methanolic fruit extract of Z. acanthopodium in Swiss albino mice by conducting acute and sub-acute toxicity tests using hematological, biochemical, ultrastructural analysis, sperm abnormality, and genotoxicity as parameters. For the acute toxicity test, mice were treated with a single dose of 5000 mg extract/kg bw of mice. While for sub-acute toxicity test, doses of 200, 500, and 1000 mg of the extract/kg bw were administered to the mice. Furthermore, a satellite group of the respective control group and the highest dose group were employed to observe the post-treatment effect that the plant may have. The acute toxicity test resulted in a significant reduction of the mean body weight gain in treated mice, but, no signs of morbidity and mortality were recorded. Sub-acute toxicity test revealed a negative effect of the plant extract on the blood and biochemical parameters. Light and electron microscopic examination of the liver and kidney showed the damaging effects of the extract on the tissues and the cellular structures. In addition, the extract induced sperm abnormalities with a significant reduction of sperm count and sperm viability, and caused an increase in the percentage of abnormally shaped sperms. The extract treatment also resulted in an increased frequency of chromosomal aberrations as well as cell death.

The use of coloring agents in food industry has dramatically increased. Children are the main consumers of colored food products and beverages and are more vulnerable to the effects of synthetic colorants. Curcumin, an active constituent of turmeric plant, has been the subject of extensive studies assessing its antioxidant properties. The present study was conducted to evaluate the protective potentials of curcumin against neurotoxicity induced by the synthetic food colorant; tartrazine. Thirty-six young male albino rats were divided into six groups; negative control (Group I), distilled water (Group II), corn oil (Group III), curcumin (Group IV), tartrazine (Group V) and tartrazine+curcumin (Group VI). At the end of the study, the rats were subjected to biochemical, histological and immunohistochemical staining for GFAP. Our results showed that tartrazine induced a significant decrease in GSH, serotonin and GABA levels and a significant increase in MDA levels in the brain as compared to control groups. Tartrazine induced apoptosis, vacuolations, congestion and cellular infiltration in the brain tissue. An immunohistochemistry study showed astrogliosis with increased expression of GFAP. Curcumin ameliorated all these effects. In conclusion, tartrazine is neurotoxic. Increased brain oxidative stress and cellular damage are contributing factors. Curcumin can prevent tartrazine-induced neurotoxicity.

The presence of one or more pesticides in a variety of mediums is responsible for their indirect toxicological events leading to cell senescence. In the present investigation, the endeavor was made to see the effect of pesticides Car- Benda-Zim (CBZ) and IMIdacloprid (IMI) alone and in combination with bone marrow-derived Mesenchymal Stem Cells (bMSCs) of buffalo origin. Isolated and cultured bMSCs were exposed to CBZ and IMI alone and in combinations at lower doses. Cells were observed for alterations in cell morphology, oxidative stress, mitochondrial damage and cellular senescence. bMSCs characterized for stem cell surface markers and found to be positive for AP, CD73 and OCT4. bMSCs exposed to IC25, IC12.5 and IC6.25 CBZ and IMI alone and combinations of IC12.5 and IC6.25 of CBZ and IMI. Results revealed significant reduction (p?0.05) in cell viability noticed on microscopic examination along with loss of normal cell morphology and increased in Reactive Oxygen Species (ROS) positive cells, cells with loss of ??m and number of senescent cells in CBZ and IMI treated groups. Lower dose combination groups showed elevated effects when compared with higher dose alone treated groups and control groups. Present findings suggest that CBZ and IMI induced cytotoxicity in bMSCs mediated via ROS production, altered ??m leading to the cell damage and predisposing senescence process. Moreover, the co-existence of CBZ and IMI in a medium has a considerably more toxic effect than their individual effect.
