Callus of the leaves, node and bud of Ipomoea obscura (L) was initiated on MS basal media supplemented with various combinations of auxins 2,4- dichlorophenoxyacetic acid (2,4-D) and naphthalene acetic acid with cytokines kinetin and benzyl amino-purin (BAP). Callus initiation was observed in all media but with varied mass. Highest percentage of callus response was obtained in combination of 2,4-D (0.8 mg/L) with kinetin (0.8mg/L); NAA (0.2mg/L) with BAP(0.2 mg/L); NAA (0.8 mg/L) with kinetin (0.8 mg/L) for explants leaves, node and bud, respectively. The callus was white in 2,4-D- and green in NAA- supplemented MS media. An efficient micropropogation protocol was developed for medicinal plant Ipomoea obscura (L.) by in-vitro culture of nodal part of mature plant. The MS media supplemented with 0.8 mg/L NAA with 0.8 mg/L kinetin induced three shoots per node in an average and was best for axillary bud proliferation.Keywords

The present paper deals with in vitro produced phytochemicals of Canscora decurrens (Dalzell) such as alkaloids, flavanoids, phenols, steroids, anthracene glycosides and triterpenoids etc for their antibacterial activities against human pathogenic strains viz. Staphylococcus aureus, Bacillus subtilis, Rhodococci sp., Escherichia coli, Proteus vulgaris, Pseudomonas sp, Salmonella sp. and Bacillus stearothermophilus. The investigation suggests that the plant may be used in therapeutic treatments of gastrointestinal disorders, diarrhoea and skin diseases.Keywords

BACKGROUND: Jaundice is commonly seen in severe malaria (approx. 2.5% patients) but hepatitis is unusual. Hepatocellular dysfunction varies from mild abnormalities in liver function tests (LFTs) to hepatic failure.
AIMS: To study the clinical, biochemical profile, complications and outcome in confirmed Plasmodium falciparum malaria cases with hepatopathy.
MATERIAL AND METHOD: This retrospective study was carried out in a tertiary care hospital in North India by reviewing slide confirmed case records of P falciparum malaria with biochemical evidence of hepatic dysfunction, admitted between 1/10/2012 and 1/10/ 2013.
RESULTS: A total of 13 patients (all male) with mean age 43.07 years, mean duration of fever prior to hospitalisation 6.5 days, were included. Fever persisted in all the patients after the onset of jaundice. Encephalopathy was present in 38.5% (5) of patients. Hepatosplenomegaly, icterus and anaemia (< 10 gm %) were found in 84.61%, 92.30% and 84.61% respectively. Predominant (> 50%) conjugated hyperbilirubinaemia was found in all the patients, with mean total bilirubin level of 21.06 mg % (1.5-54). Hyper-hyperbilirubinaemia (> 10 mg %) was associated with renal failure (serum creatinine > 2.0 mg/ dl) in 77.8% (7) cases. Mean AST, ALT and ALP levels were 164.84 IU/L (38-665), 75 IU/L (43-160) and 132.46 and > 3 upper limit of normal (ULN) was more common with AST than ALT (53.84% vs. 15.38%). Thrombocytopenia was seen in all the patients with mean platelet count of 43,853 /mm3. Most patients had only mild derangement of PT with mean INR of 1.30 (1-1.74). Main complications seen were acute renal failure (ARF) (88.89%), septicaemia (77.79%), acute respiratory distress syndrome (ARDS - 22.22%). ICU care was required by 69.23% of the patients. Mortality was 38.46% (5) and 53.84% patients (8) recovered.
CONCLUSION: Malarial hepatitis is a serious complication in patients presenting with P. falciparum malaria. Renal dysfunction is more common in those with hyper-hyperbilirubinaemia. Whether this is the cause, or effect, is difficult to hypothesise.

We report in this note the farthest recorded liquefaction phenomenon near Jammu as sequel to the Mw 7.6,8 October, 2005 Muzaffarabad earthquake of Kashmir. The most common liquefaction features were sand blows and longitudinal en echelon fissures. Based on the occurrence of liquefaction and minor damage to the pakka houses it is suggested that the intensity would have been around VI-VII on MSK scale in this region.Keywords

In more than 95% of patients, the cause of mesenteric ischaemia is diffuse atherosclerotic disease which decreases the flow of blood to the bowel. As the atherosclerotic disease progresses, symptoms worsen. We present a case of a 76 year diabetic male who was on treatment for ischaemic heart disease for the last five years. He presented with recurrent, dull, diffuse post-prandial abdominal pain for two years. The pain was classical of mesenteric ischaemia, and would occur half to one hour after taking meals. It reached its peak in next one hour and would subside within 3-4 hours. CT angiogram was done which revealed diffuse atherosclerosis of abdominal aorta with plaques obstructing origin of superior mesenteric artery and extending into bilateral common iliac arteries. The atherosclerosis is most common cause of chronic mesenteric ischaemia (CMI) but such diffuse involvement is rare.Keywords

A study was undertaken in the tail end command of Western Yamuna Canal Command (WYCC) in Jhajjar district, Haryana,to assess the socio-economic status and coping strategies adopted by farmers under waterlogging and saline environments. Perception on water management and control of problem of waterlogging and salinity of 100 selected farmers is reported in this study. About 85 to 100 per cent of the respondents strongly endorsed that the poor maintenance of irrigation channels, canal siltation and weed growth, seepage from the distributaries and minors and irregular supply of canal water were the major factors responsible for waterlogging and subsequent land degradation in the command area. In all, 85 per cent of the respondents opined about non-existence of any scheme by the government agencies for maintenance of field channels. As coping strategies, farmers manage the problem by cleaning field irrigation channels, creation of open ditch drains, controlled irrigation methods and increasing the seed rate besides green manuring with varying degrees of success. Farmers of the study area also expressed the need for knowledge dissemination mechanism with technology details, funding opportunities and effective and efficient functioning of water user associations besides involvement of all farmers to enhance productivity from irrigated saline environment.Full Text
