Effects of Co‐composting of Municipal Solid Waste and Pigeon Pea Biochar on Heavy Metal Mobility in Soil and Translocation to Leafy Vegetable Spinach

Bulletin of Environmental Contamination and Toxicology - An experiment was conducted to study the effects of co-composted products of municipal solid waste (MSW) and pigeon pea biochar (PPB) on...     

RENAL TRANSPLANTATION – AN EARLY EXPERIENCE

Renal transplant (RT) is now a therapy of choice for end stage renal disease (ESRD). The Nephrology Unit, Asvini started functioning in Dec 90 and to date 1298 sittings of hemodialysis have been given to 45 patients. Of these, 35 were in ESRD and 11 patients underwent renal transplantation at this hospital during the period Jan 91 – Dec 93. One patient expired after 18 months of transplantation due to infection. Early experience in screening patients for RT, use of immunosuppression, management of rejection episodes and protocol are presented with special emphasis on its relevance to the Armed Forces.KEY WORDS: Transplantation, Renal Failure, Immunosuppression, Rejection     

HIV AND TUBERCULOSIS CO-INFECTION IN A REFERRAL CHEST HOSPITAL

Serving personnel of Armed Forces admitted with tuberculosis between Apr 1996–1999 were evaluated for co-infection of tuberculosis and HIV. Sixty (1.06%) of tuberculosis patients were found to be HIV positive. Initial test was done by spot kits and subsequently confirmed by ELISA on two different samples. Majority of the cases were in sexually active age group 48 (80%). Alcohol and smoking was associated in 80% cases. Thirty six (60%) were sputum smear positive for AFB. Twenty eight (46.7%) gave history of exposure to sex workers. Family members were not available for study. Sero prevalence of HIV in association with tuberculosis is less in Armed Forces compared to civil population.KEY WORDS: HIV, Seroprevalence, Tuberculosis     

Preliminary evaluation of in vitro cytotoxicity and in vivo antitumor activity of Premna herbacea Roxb. in Ehrlich ascites carcinoma model and Dalton's lymphoma ascites model

In the present study, the root nodules of Premna herbacea Roxb. (PH) was investigated for its in vitro cytotoxicity and in vivo antitumor activity. Two extracts, aqueous and alcoholic; two fractions of alcoholic extract, ethyl acetate and butanol fractions were screened for their in vitro cytotoxicity by brine shrimp lethality (BSL) assay, trypan blue exclusion assay and MTT assay. Alcoholic extract and its ethyl acetate fraction were found to be the most effective in BSL assay, trypan blue exclusion assay. In vivo antitumor activity was screened in the Ehrlich ascites carcinoma (EAC) model and the Dalton lymphoma ascites (DLA) model. The extracts and the fractions were tested at two dosages (250 and 500 mg/kg) by intraperitoneally (i.p.) route on every alternate day upto 13th day. Cisplatin was used as positive control in both studies in single dose (day 1) 3.5 mg/kg by i.p. route. In EAC model, ascites tumor was induced by inoculating 2.5 million of EAC cells i.p. alcoholic extract at 500 mg/kg was the most effective in elevating MST, reduction in body weight in EAC induced tumor. Only the effective extract i.e., alcoholic extract were studied for hematological and antioxidant parameter. It showed a restoring effect on altered hematological parameters and a significant improvement in biochemical parameters at 250 mg/kg dose of alcoholic extract. These results explain the toxicity of 500 mg/kg might be high. In the Dalton lymphoma ascites (DLA) model, solid tumor was developed by i.m. injection of 1 million DLA cells. Both the extracts and the fractions possessed potent antitumor activity against solid tumor models by significantly reducing the solid tumor weight and volume.     

Varietal Spectrum of Seed Production of Pulses in India: An Updated Approach

Pulses play a pivotal role in Indian agriculture as they are considered as the basic source of protein in Indian diet. Therefore, the biggest concern is to feed country’s 1.2 billion population with balanced diet and to maintain the production in line with the growth of population. To step-up production of pulses, quality seed is one of the crucial factors on which the performance and efficiency of other inputs or factors depends. Due to painstaking efforts of different organizations the overall breeder seed production of major pulses increased more than 130 % in the last decade. Breeder seed production in urdbean has continuously increased during the last five years. Similarly, an increasing trend has been seen in pigeonpea (except for the year 2010) with recording the highest seed production of 131.72 t in 2012. Among rabi pulses, breeder seed production of chickpea was highest in 2011 with 1,171.79 t production whereas in lentil and fieldpea it was highest as 53.14 and 94.63 t production in 2011–2012 respectively. The leading varieties are generally those which are high yielding along with resistance to biotic stresses e.g. JG-11 and Vijay in chickpea, BSMR 736 and TJT-501 in pigeonpea, Pant U 31 and IPU 02-43 in urdbean, SML-668 and Samrat in mungbean, Pant L-8, HUL 57 and JL-3 in lentil and Prakas, Vikas and Aman in fieldpea. They are the most preferred varieties with maximum seed indent. Therefore, a more concerted effort would be needed for evolving high yielding varieties having resistance/tolerance to abiotic stresses along with resistance to major biotic stresses in the coming years.
