Enteric non-A, non-B hepatitis: epidemics, animal transmission, and hepatitis E virus detection by the polymerase chain reaction.

We studied epidemics of viral hepatitis occurring at three different places in India. One was a combined epidemic due to hepatitis E virus (HEV) and hepatitis A virus (HAV) infections. In this epidemic, HAV affected children below 10 years of age, whereas HEV infected the young adult population. HEV was transmitted to rhesus monkeys (Macaca mulata) and confirmed by the polymerase chain reaction (PCR) on bile from the animals. Fecal material from acutely infected patients in one of the epidemics was also found positive for HEV RNA by PCR. This may help in confirming the nature of future epidemics. The bile and liver from experimental animals can be used as a source of material for further virological and molecular biological studies of HEV.

Intraspecific variations in pollen extracts ofRicinus communis(castor bean) prepared from different source materials

Abstract Pollen of Ricinus communis, an important aeroallergen was collected from different stages of development of flower, different time intervals, different years and different places in India, to see variability, if any, in the protein content and protein profiles of the extracts. The protein content showed significant variation in the extracts from different sources. IEF and SDS — PAGE protein profiles from pollen antigens of mature buds and flowers showed almost similar pattern. However, appreciable variation was recorded in the protein pattern of pollen extracts from different years and places. It is therefore suggested to have a comprehensive quality control of pollen raw materials before processing for antigenic extracts.

A laboratory method for assessment of nitrogen availability in soils

The nitrogen availability index determined as nitric acid potential gave significant correlations with the yield of bajra, wheat and rice crops in experiments conducted on alluvial soils of Delhi at the IARI Farm. The coefficient of correlation was also the highest when data from similar experiments on wheat on alluvial, grey brown, sierozem and medium black soils from different places in India were pooled. It was found that the nitric acid potential seems to be independent of soil type and is also applicable to various agroclimatic conditions.
