The current study focuses on the vertical profile of different geochemical fractions of phosphorus-loosely bound(Lo–P), aluminium bound(Al–P), iron bound(Fe–P), calcium bound(Ca–P), and organic bound phosphorus(O–P) along with ecological risk assessment of sediment cores from Chilika Lake, eastcoast of India. The percentage contribution of the different fractions to the sedimentary phosphorus in the sediment column of the whole lake are on the order: O–P(33.2%) 4 Ca–P(20.3%) 4 Fe–P(18%) 4 Al–P(6.7%) 4 Lo–P(0.35%). The Phosphorus Pollution Index(PPI) revealed the contamination of lake sediment with phosphorus. The principal component and cluster analyses highlighted the anthropogenic contribution of phosphorus. The negative loading of Ca–P with Ca points towards its origin from marine shells. The discriminate analysis showed that the variables like Ca–P, bio-available phosphorus(BAP), and p H were able to effectively discriminate the sectors in a significant manner.

The aim of the present review article is to investigate the herbs which can alter the levels of hormones like Follicle stimulating hormone, Prolactin, Growth hormone, Insulin, Thyroxine, Estrogen, Progesterone, Testosterone, and Relaxin etc. Hormones are chemical signal agents produced by different endocrine glands for regulating our biological functions. The glands like pituitary, thyroid, adrenal, ovaries in women and testes in men all secrete a number of hormones with different actions. However, when these hormones are perfectly balanced then people become healthy and fit. But several factors like pathophysiological as well as biochemical changes, disease conditions, changes in the atmosphere, changes in the body, diet changesetc. may result in imbalance of various hormones that produce undesirable symptoms and disorders. As medicinal plants have their importance since ancient time, people have been using it in various ways as a source of medicine for regulation of hormonal imbalance. Moreover, it is observed that certain herbs have a balancing effect on hormones and have great impact on well-being of the people. So, considering these facts we expect that the article provides an overview on medicinal plants with potential of altering hormone level.

Objective: To evaluate the anti-hyperprolactinemic effect of methanolic extract of Tinospora cordifolia against antipsychotic/neuroleptic drug induced hyperprolactinemia. Methods: A total of 48 Wistar albino rats were chosen in the study. To induce hyperprolactinemia, haloperidol at 5 mg/kg/day was intraperitoneally administered for 16 continuous days and sulpiride at 20 mg/kg/day was administered intraperitoneally for 28 continuous days. Methanolic extract of Tinospora cordifolia at 200 mg/kg/day and 400 mg/kg/day were administered orally 30 min before administration of haloperidol and sulpiride for 16 and 28 days, respectively. Then, we had evaluated prolactin, dopamine and antioxidant status in the treatment group as compared to haloperidol and sulpiride. Results: There was a significant (P<0.05) increase in serum prolactin level and decrease in dopamine level in the haloperidol and sulpiride treated animals. However, methanolic extract of Tinospora cordifolia significantly (P<0.05) decreased serum prolactin level and increased brain dopamine level. Further, superoxide dismutase and catalase level were also decreased significantly in the haloperidol and sulpiride treated groups as compared to those of the control group and the antioxidant status was restored significantly on treatment with methanolic extract of Tinospora cordifolia. Furthermore, methanolic extract of Tinospora cordifolia also reduced total leukocyte count, and increased red blood cell count and hemoglobin concentration. In addition, the spleen did not show signs of infection or inflammation in the experiments. Conclusions: Methanolic extract of Tinospora cordifolia has a significant anti-hyperprolactinemic effect which may be attributed to neuroprotective and antioxidant effects of its signature constituents like stepharanine.

Distribution and enrichment of six elements (iron, zinc, copper, lead, cadmium and manganese) in surface bed sediments, collected from seventeen selected locations during pre-monsoon and postmonsoon periods, of the tropical Chottanagpur plateau river Subarnarekha along with the ecological risks involved were investigated. Owing to the rich occurrence of mineral resources, the Subarnarekha river basin has a large scale presence of industrial and mining units especially in the Indian State of Jharkhand. An assessment, which involved examining distribution pattern of elements, comparative studies with sediment quality guidelines (SQGs) and geochemical background values and a sequential and integrated index analyses approach (containing contamination factor (CF), pollution load index (PLI), contamination degree (CD), enrichment factor (EF), geo-accumulation index (Igeo) and potential ecological risk index (PERI)), was followed to estimate enrichment and risks of elements in the bed sediments. Sediments collected from areas having abundance of population, industrial conglomerates and mining units recorded elevated element concentrations, which exceeded SQGs, and significantly higher values of CF, CD, PLI, EF, Igeo and PERI. Cadmium demonstrated surprising regularity in its enrichment;contributed most to the ecological risks;and high toxicity risks due to cadmium exceeded 64% of the sites. Moreover, chronic exposures of other elements would also lead to similar ecological risks. In addition to revealing potential ecological risks due to cadmium and other elements our investigation markedly highlighted anthropogenic control over sediment quality deterioration and some immediate sediment quality management strategies are needed to remediate and control river bed contamination.
