ABSTRACT
A large number of putative rhizobial isolates were obtained from the root nodules of various chickpea cultivars growing in agricultural research fields. Of these, thirty were selected and characterized for traits, such as, generation time, intrinsic azide resistance and several symbiotic characters.

Insulin-dependent diabetes mellitus is associated with renal failure, diabetic retinopathy, neuropathy and vasculopathy. We report the first successful simultaneous pancreas-kidney transplant in India in a young diabetic with renal failure. The dual transplant has cured his diabetes and renal failure and has had a beneficial effect on his neuropathy, retinopathy and quality of life. Obstacles to dual transplant in India include a lack of suitable recipients and a cadaver donor programme that is still in its infancy.

BACKGROUND AND AIMS: The anaesthetic potency of volatile anaesthetic agents is measured by the minimum alveolar concentration (MAC) required to suppress response in 50% of subjects. We studied the effect of epidural morphine on MAC of isoflurane in humans. SETTINGS AND DESIGN: A prospective single-blind study designed to study the effect of epidural morphine on MAC of isoflurane. SUBJECTS AND METHODS: Forty-eight patients were randomly divided into two groups - Group I patients received 3 mg morphine in 10 ml saline, and Group II patients received 10 ml saline epidurally. Anaesthesia was induced with isoflurane in oxygen and nitrous oxide. Later nitrous oxide was discontinued and MAC of isoflurane determined using modified Dixon's method of sequential sampling. RESULTS: Epidural morphine resulted in a significant reduction in MAC of isoflurane, 0.98 vs. 1.14 in control group (p<0.05). CONCLUSIONS: Epidural administration of 3 mg morphine in 10 ml saline decreased the MAC of isoflurane.

Legume-Rhizobium symbiosis is a multistep process characterized by the formation of root nodules on the host plant. A number of genes from both symbiotic partners share information during the interaction process. Nodulation genes (nod, nol and noe) have been classified as common nodulation genes and host specific (hsn) nodulation genes. Though common nodulation genes are enough to form root nodules, host specific nodulation genes are needed for specific interaction leading to formation of functional nodules. Core lipochitooligosaccharides (LCOs), the products of common nodulation genes are modified by the action of host specific nodulation genes. LCOs seem to be present in legumes as well as nonlegume and are known to act as a morphogen by acting as auxin-transport inhibitor. The understanding of Nod factor may contribute to reveal complex biological functions such as developmental regulation, signal transduction and plant morphogenesis.

A prospective study was carried out on the incidence of pulmonary complications in 728 patients who underwent major surgical procedures at a reputed hospital in New Delhi. These patients were preoperatively assessed on the basis of history, clinical examination and bedside pulmonary function tests including PEFR, VC, FVC and FEV1. On the basis of these criteria, 212 patients had significant preoperative pulmonary disease, while 516 had normal lung functions. Postoperative pulmonary complications developed in 7.69 per cent of the patients. They were more frequent in smokers (P < 0.001) and in those with preoperative pulmonary dysfunction (P < 0.001). Their incidence was greater following thoraco-abdominal and musculoskeletal and miscellaneous operations compared to lower abdominal surgery (P < 0.001). The incidence was also higher following exposure to general anaesthesia compared to regional anaesthesia (P < 0.05). Pneumonia and atelectasis were the most common postoperative pulmonary complications. It was observed that the recovery of pulmonary functions was delayed in patients who developed postoperative pulmonary complications.

The total genomic DNA of R. leguminosarum Rld164 (trp, sms, azi) was cloned in the EcoR1 site of the wide host and conjugally transferable cosmid vector pLAFR1. The average insert size in the gene clones of the bank was found to be 21.3 Kb. The strain R. leguminosarum Rld7 (leu-1) was employed as recepient to conjugally transfer and thus isolate the complementary leu+ allele carrying clones from the gene bank.
