Bioremediation of Industrial Effluent using Cyanobacterial Species: Phormidium mucicola and Anabaena aequalis

Different Industries discharge effluent in different water bodies, which is the only reason of pollution. The main objective of the present study was to investigate the biodegradation and biosorption capacity of some potential cyanobacterial species; Phormidium mucicola and Anabaena aequalis in Textile and Pharmaceutical industries, Mandideep, Bhopal Madhya Pradesh, India. Industrial effluents are contaminated with heavy metal. The effluents were subjected to biological treatment using axenic cyanobacterial strains as batch system for 7 days. Removal efficiencies of the different contaminants were evaluated and compared. Results confirmed the high efficiencies of the investigated species for the removal of the target contaminants which were species and contaminant-dependent. BOD and COD recorded 91.18 and 82.54% as maximum removal efficiencies achieved by Anabaena aequalis. The highest removal efficiencies of the total suspended solids recorded 53.23% achieved by Phormidium mucicola, while 41.61% was recorded as the highest TDS. Concerning the contaminant metals, Phormidium mucicola showed the highest biosorption capacity where 86.12 and 94.63% removal efficiencies were achieved for Zn and Cu, respectively. In conclusion, results of the study confirmed the advantageous potential of using the tested cyanobacterial species for the bioremediation of industrial effluent and clearly showed the quality improvement of the discharged effluent which in turn will eliminate or at least minimize the expected deterioration of the receiving environment.

Treatment practices in pulmonary tuberculosis by private sector physicians of Meerut, Uttar Pradesh.

Background. Majority of the qualified medical practitioners in the country are in the private sector and more than half of patients with tuberculosis (TB) seek treatment from them. The present study was conducted with the objective of assessing the treatment modalities in pulmonary tuberculosis by the private physicians in Meerut City, Uttar Pradesh, India. Methods. A cross-sectional study was carried out covering all the private physicians (graduates and postgraduates in Medicine and Chest Diseases) registered under the Indian Medical Association, Meerut Branch (n=154). The physicians were interviewed by a pre-designed and pre-tested questionnaire about the treatment modalities practiced by them. Results. Only 43.5% private physicians had attended any Revised National Tuberculosis Control Programme (RNTCP) training in the past five years. Only 33.1% of them were aware of the International Standards of Tuberculosis Care (ISTC). Fifty-three different regimens were used to treat the patients. Majority of physicians (76%) prescribed daily regimens while 24% administered both daily and intermittent treatment. None of the private physicians prescribed exclusive intermittent regimen. Eighty-seven different treatment regimens were used for the treatment of multidrug-resistant TB (MDR-TB) with none of them prescribing standard treatment under RNTCP. Conclusion. As majority of private practitioners do not follow RNTCP guidelines for treating TB, there is an urgent need for their continued education in this area.

Aluminium phosphide poisoning: management and prevention.

Death by Aluminium phosphide (AIP) and organo-phosphide poisoning are the commonest forms of poisoning in India. Aluminium phosphide is used as rodenticide and pesticide in grain storage facilities. It produces phosphine gas, which results in mitochondrial poisoning. There is no known antidote for AIP poisoning. The effects of AIP poisoning, mediated by phosphine and mechanism of action have not been established.The information related to this poisoning is available in the literature and substantiated by practical experience. Liberated phosphine cannot be detoxified but Magnesium sulphate has been reported to be effective. Another remedy can be rapid absorption by coconut oil which might be helpful. Treatment consists of gastric lavage with potassium permanganate solution, oral administration of charcoal and sorbitol suspension, intravenous administration of sodium bicarbonate, magnesium sulphate and calcium gluconate, and oral administration of sodium bicarbonate and coconut oil. Use of coconut oil for treatment in this poisoning is suggested, although clinical trials and scientific approval is still awaited. Every suggestion, news regarding new modality of treatment for this poisoning needs to be shared in the interest of saving precious human lives. It is with this aim the present paper is written.

Adult choroid plexus papilloma: cause of sudden death.

Choroid plexus papilloma (CPP) is a rare, benign neoplasm, relatively more common in childhood. It is associated with signs and symptoms of increased intracranial pressure, frequently in association with obstructive hydrocephalus. CT and MRI are the investigations of choice and are diagnostic. Sudden deaths have been reported, but are very unusual. A 41 year old male was brought for medico-legal autopsy examination on ground of sudden death. He was reported to have headaches over a long period of time. On autopsy examination, massive sub-arachnoid hemorrhage was seen on both the cerebral hemispheres and cerebellum. A cyst measuring about 1 cm diameter was found in choroid plexus of right lateral ventricle. On histopathological examination, it was found to be a choroid plexus papilloma. Calcification was also evident in the papilloma. From medico-legal aspect, the present case reveals an unusual cause for sudden death in an adult male. The pathology could have been diagnosed easily by CT scan or MRI. When diagnosed, it has good survival rate, the morbidity depending on the extent of pathological effects. The present case was likely to have survived having minimal effects with appropriate treatment had he been diagnosed. The pathology is rare and a suspicion for this pathology in the adult male was not expected, but a CT scan to investigate chronic headache was warranted. Absence of such a suggestion leading to death, which could have been preventable, is sufficient ground for charge of professional negligence.

Deccan volcanism, the KT mass extinction and dinosaurs

Recent advances in Deccan volcanic studies indicate three volcanic phases with the phase-1 at 67.5 Ma followed by a 2 m.y. period of quiescence. Phase-2 marks the main Deccan volcanic eruptions in Chron 29r near the end of the Maastrichtian and accounts for ~80% of the entire 3500 m thick Deccan lava pile. At least four of the world’s longest lava fl ows spanning 1000 km across India and out into the Gulf of Bengal mark phase-2. The fi nal phase-3 was smaller, coincided with the early Danian Chron 29n and also witnessed several of the longest lava fl ows. The KT boundary and mass extinction was fi rst discovered based on planktic foraminifera from shallow marine intertrappean sediments exposed in Rajahmundry quarries between the longest lava fl ows of the main volcanic phase- 2 and smaller phase-3. At this locality early Danian (zone P1a) planktic foraminiferal assemblages directly overlie the top of phase-2 eruptions and indicate that the masse extinction coincided with the end of this volcanic phase. Planktic foraminiferal assemblages also mark the KT boundary in intertrappean sediments at Jhilmili, Chhindwara, where freshwater to estuarine conditions prevailed during the early Danian and indicate the presence of a marine seaway across India at KT time. Dinosaur bones, nesting sites with complete eggs and abundant eggshells are known from central India surrounding the hypothesized seaway through the Narmada-Tapti rift zone. A Maastrichtian age is generally assigned to these dinosaur remains. Age control may now be improved based on marine microfossils from sequences deposited in the seaway and correlating these strata to nearby terrestrial sequences with dinosaur remains.

The origin and early evolution of whales: macroevolution documented on the Indian Subcontinent.

The origin of whales (order Cetacea) from a four-footed land animal is one of the best understood examples of macroevolutionary change. This evolutionary transition has been substantially elucidated by fossil fi nds from the Indian subcontinent in the past decade and a half. Here, we review the fi rst steps of whale evolution, i.e. the transition from a land mammal to obligate marine predators, documented by the Eocene cetacean families of the Indian subcontinent: Pakicetidae, Ambulocetidae, Remingtonocetidae, Protocetidae, and Basilosauridae, as well as their artiodactyl sister group, the Raoellidae. We also discuss the infl uence that the excellent fossil record has on the study of the evolution of organ systems, in particular the locomotor and hearing systems.

Obstetric history and reproductive tract infections among married female (15-44 yrs.) in rural area of district Meerut, U.P.

The prevalence of RTIs in 600 married females (15-44 yrs.) representing 12 subcentre villages of Daurala block of Meerut was 35.3%. The reproductive tract infections were significantly associated with place of last delivery (P< 0.001), person conducted the last delivery (P< 0.001) and in women had history of abortions (P< .005).

Antiviral profile of Nyctanthes arbortristis L. against encephalitis causing viruses.

The ethanolic extracts, various fractions and two pure compounds isolated from the plant N. arbortris were tested against Encephalomyocarditis Virus (EMCV) and Semliki Forest Virus (SFV). Pronounced in vitro virus inhibitory activity was observed with the ethanolic and n-butanol fractions as well as with the pure compounds arbortristoside A and arbortristoside C. In addition, ethanolic extracts and n-butanol fraction protected EMCV infected mice to the extent of 40 and 60% respectively against SFV at a daily dose of 125 mg/kg body weight.

2-CdA in the treatment of hairy cell leukaemia.

INTRODUCTION: Hairy cell leukaemia (HCL) is a rare lymphoproliferative disorder. Treatment options available are splenectomy, interferon, DCF and 2-CdA. 2-CdA is considered to have curative potential as proved by the other studies. METHODS: We gave 2-CdA in a dose of 0.09/kg/day as a continuous infusion in sixteen patients of hairy cell leukaemia. RESULTS: Three patients developed neutropenia post transfusion. At the end of three months all patients were in remission. Two patients relapsed at the median follow-up of 15 months. CONCLUSION: 2-CdA in HCL can achieve complete remission, prolonged survival and care as well.

Prevalence of anaemia among adolescent girls in rural area of District Meerut, U.P.

The prevalence of anaemia in 504 adolescent girls (10-18 yrs) representing 24 subcentre villages of Daurala block of Meerut was 34.5%. The prevalence of mild, moderate and severe anaemia among adolescent girls was 19.0%, 14.0% and 1.4% respectively. Majority (55.2%) were having mild anaemia and only 4.0% had severe anaemia. Anaemia was found to be significantly associated with educational status (P < 0.05), birth order (P < 0.05), awareness regarding anaemia (P < 0.05) and marital & obstetric status (P < 0.05) with no association with age, anthropometry and menarcheal age (P > 0.05).

Reproductive tract infections among rural women in Meerut.

The present study was done among 500 women of reproductive age group. Study revealed overall prevalence rate of RTI of 44.8%. Excessive vaginal discharge was the most common presenting symptom (42.0%). Inspite of such an high prevalence of reproductive tract infections, only 22.8% of the women sought treatment for their problem. The study suggests to improve the awareness about RTI and its treatment facility among women and also recommends to develop a strategy to train and reorient the health personnel.

Examination stress: changes in serum cholesterol, triglycerides and total lipids.

Serum cholesterol, triglycerides and total lipids were estimated in twelve students exposed to varying degree of examination stress. Serum cholesterol and triglycerides exhibited a rise proportional to degree of examination stress whereas total lipids exhibited an initial rise followed by a fall. Values of all these parameters attained control level when the stress was over. The rise in serum cholesterol and triglycerides seems to be due to stress induced changes in hormonal levels and peripheral lipolysis respectively.

Production & evaluation of a monoclonal antibody against human myeloperoxidase.

We describe the production of a mouse monoclonal antibody (H2E1) against human myeloperoxidase antigen. After production and characterisation, this antibody was compared with commercially available monoclonal antibodies, cytochemical myeloperoxidase and previously produced polyclonal antibody. Reaction with various cell lines proved that this monoclonal antibody was specific for myeloid lineage. This monoclonal showed positivity in 81.8 per cent of acute myeloid leukaemias whereas the polyclonal antibody was 100 per cent positive. We found that the polyclonal antibody was more sensitive as compared to the monoclonal. This is probably due to the lack of recognition of individual epitopes on the antigen. We recommend the use of antibodies which have different epitope recognition as most specific for myeloperoxidase.

In vitro anti-vaccinia virus activity of some marine plants.

Seventy three marine plant extracts were tested in vitro in chick embryo fibroblast cell culture and their anti-vaccinia virus activity was evaluated in terms of reduction in number of plaques by the extracts. Only seven extracts were found to show the activity. Sargassum wightii, a seaweed had the highest activity, reducing 65 per cent of plaques formed by vaccinia virus.

Clinicosocial aspect of osteo-articular tuberculosis.

The study constituted clinicosocial analysis of 194 cases of osteo-articular tuberculosis. The disease was common in 1st and 2nd decades of life but not rare in old age with male preponderance. Majority of the patients were from rural area belonging to lower economic classes. Lesions were usually solitary (96.4%) situated in the weight bearing bones and joints (88.66%). Spinal tuberculosis was commonest (48.97%). The onset of disease was insidious in 94.8% cases. Chronic pain, swelling, impaired movements, deformities, sinus and cold abscess were found to be salient features of disease. Negligence and secondary infection were common.
