New researches in the field of biological sciences are creating new problems which were hitherto not faced. New techniques in biotechnology have paved way for transplantation for kidney, heart and liver successfully. In vitro fertilization, surrogate mothership, researches in totipotent stem cells which are capable of cloning are creating moral dilemma for the scientists. These techniques have immense capacity for the wellness of human beings. But there is every possibility of their misuse. Should researches in biotechnology be allowed unconditionally or there be some guiding principles? If the technique of cloning is perfected what will be the fate of the society which is based on conjugal love and trust? Should abortion and euthanasia be allowed? These questions need a clear answer. Here comes the role of bioethics to deal with such queries. In our view no such laws can be framed which can guide scientists in each and every case. Each case is specific and requires particular attention. There should be some norms for individual decision taker which are given in spiritual book of Hindu 'ShrimadBhagavataGeeta'. With the help of this technique of decision making specific cases can be dealt with. © 2012.

The present investigation was performed to monitor the HCHs (HCH isomers), DDTs (DDT and its metabolites), chlorpyrifos, plasma levels of estradiol-17β (E2) and gonadosomatic index (GSI) between the sampling sites of the non-polluted ponds of Gujartal, Jaunpur (reference site) and the polluted river Gomti (Jaunpur), affecting the reproductive physiology of some edible female catfish during pre-monsoon season. The HCHs, DDTs and chlorpyrifos were measured by gas liquid chromatography (GLC) and hormone by Enzyme-Linked Immunosorbent Assay (ELISA). The results indicated that the presence of HCHs, DDTs and chlorpyrifos was very high in the catfish captured from polluted river as compared from the conspecific fish captured from reference site. The GSI and E2 declined in female catfish of polluted site when compared to same species from reference site. Results have also indicated that catfish contained high bioaccumulation of HCHs, DDTs and chlorpyrifos which was beyond permissible limit as compared to the female catfish of the reference site. In conclusion, the fishes of river Gomti were highly polluted when compared with the fish of reference site as was evident from high levels of tissue bioaccumulation of HCHs, DDTs, chlorpyrifos and decreased levels of plasma E2 inhibiting the reproductive physiology of these species at receptor level. However, the levels exceeded maximum residue limits (MRL) as recommended by Codex, hence it is suggested that the fish containing pesticide residues beyond permissible limit should be avoided for the food purposes.

Present investigation has been carried out on the sloping habitat of 'Gujar Tal' lake ecotone belts by selecting two different sites, I (12° slope) and II (9° slope) at Jaunpur (U.P.) under the influence of two respective natural rainfall events, i.e. 11 mm in 55 minutes and 15 mm in 1 hour and 25 minutes, on two different days during rainy season. The wetlands and their ecotones are under threat of degradation all over the world. Therefore, findings of nutrients (N and P) conservation by natural community, i.e run-off concentration in vegetated and bare plots during the experiments will be helpful in ecological management of present biotopes. The vegetated plots showed lower values of nutrients loss (N & P) in run-off water in eroded soil in comparison to bare plots at both the sites (I and II). Among the two sites maximum concentration of nitrogen was 4.56 (site I) and 4.32 (site II) mg L -1 and phosphorous was 0.99 (site I) and 0.54 (site II) mg L -1 in run-off water, in 11 mm natural rainfall event. In contrast, for eroded soil their respective values, i.e. N, 5.83 (site I) and 5.57 (site II) mg L -1 and P, 0.81 (site I) and 0.67(site II) mg L -1 were more in eroded soil, again in 11 mm natural rainfall event. © EM international.

Effects of sublethal treatments (20% and 60% of 24h LC50) ofextracts of plants and synthetic molluscicidesagainst snails Lymnaea acuminate will be studied. The synthetics molluscicides (Permethrin and Cypermethrin) caused a significant reduction in the fecundity, hatchability and survival of the young snails. Treatment with the plant extracts increased the hatching period (9-21)of snails with respect to control (7-9 days). Plant extract causes significantly (p<0.05) reduction in the fecundity, hatchability and survival of the young snail Lymnaea acuminata.A significant recovery was observed when the snails treated with plant extracts. Withdrawal of the snails from constituent treatments after 96h with movement of fresh water enabled a significant reproductive recovery in the snail.

Effect of cumulative doses (7, 14 and 28 mg kg(-1) body weight) of testosterone (T) and estradiol-17 beta (E2) on total phospholipids (TP), phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylinositol (PI) and phosphatidylethanolamine (PE) in tissues were investigated during the gonadal recrudescence, in prespawning phase of the annual reproductive cycle in intact and ovariectomized freshwater catfish, Heteropneustes fossilis. After ovariectomy, the hepatic levels of TP and PE were elevated and remained unaffected for PC, PS and PE when compared with control. In general, T and E2 were stimulatory fora specific class ofphospholipid in tissues of intact and ovariectomized catfish. These effects were higher at 14 and 28 mg kg(-1) body weight in ovariectomized catfish whereas 7 mg kg(-1) body weight of T and E2 have pronounced effect in intact ovaries. In conclusion, the various phospholipid biosynthesis were under T and E2 dependent. Among the phospholipid, the PC was the main constituent and was sex steroid dependent biosynthesis during prespawning phase.
