CINI's approaches to intervention: an innovative strategy to combat malnutrition in India.

The Child in Need Institute (CINI) has been working toward sustainable health and nutrition development for women and children for the last twenty-six years. During the initial stages, the Institute focused on treatment and prevention of malnutrition in children under five years of age. Over the years, the program strategies have shifted to a more holistic lifecycle approach. This approach targets individuals during crucial periods of their lives--pregnant women, children (0-2 years of age) and adolescents (10-19 years of age)--as well as other vulnerable segments of the population. To reach out to these target groups, the Institute uses a three-pronged strategy that includes case management, behavior change communication, and linkage formation. Programs are either community- or center-based depending upon the need of the populations. CINI's current strategy has shown positive trends in improving the health and nutrition status of women, children, and adolescents in the community. Results include reduction of low birth weight babies, increase in proper antenatal care, reduction of severely malnourished children, decrease in maternal and infant mortality and morbidity rates, and improvement in community involvement in all reproductive and child health programs. CINI is currently monitoring its performance and activities to carry out operations research for providing further evidence for the effectiveness of its interventions.

Antigen-specific non-immunoglobulin "antibody'-like molecules in rhesus monkey serum.

The presence (in sera of rhesus monkeys) of four antigen-specific molecules with different electrophoretic mobilities apart from conventional immunoglobulins has been recognized. Rhesus monkeys have been primed with rabbit erythrocytes (RRBC) and the antigen-specific molecules in the serum have been fished out by absorption onto RRBC. Antisera have been raised in rabbits against such molecules and analysed by immunoelectrophoresis. The antigen-binding property of the four molecules, which do not resemble conventional immunoglobulins has been confirmed by enzyme immunoelectrophoresis. The possibility of these molecules being products of T lymphocytes in the light of observations reported in recent years is discussed.

2-Mercapto-ethanol enhancement of agglutination reaction--a possible in vitro serological correlate for assessment of functional immunity in simian malaria.

Conventional indirect haemagglutination test was performed in rhesus monkey sera (collected from Plasmodium knowlesi infected animals) with and without prior treatment of sera with 2-mercapto-ethanol (2-ME). Surprisingly, many sera samples showed significant enhancement of final titre with 2-ME. The 2-ME enhancement effect was more pronounced in the sera of hyperimmune monkeys on further injection of antigen or parasites. It was also noticeable in the sera during primary drug-suppressed P. knowlesi infection and appeared to have a bearing on the immune status of the animals to rechallenge. The use of a soluble antigen prepared from P. knowlesi infected erythrocytes was found to be essential in IHA test to demonstrate the 2-ME enhancement effect. Antigen prepared from freed parasites (commonly used) failed to show a similar effect in IHA. The possible role of certain T-lymphocyte products - antigen binding, non-agglutinating, 2-ME sensitive molecules - in malarial immunology has been proposed.

Effect of experimental diabetes and glucagon on cAMP-dependent protein kinase in rat liver.

Liver protein kinase was determined in the absence and presence of cAMP4. Experimental alloxan diabetes resulted in a decrease in total protein kinase (+cAMP) and an increase in the activity ratio (-cAMP) divided by (+cAMP) in liver. Insulin treatment of diabetic rats reversed the observed changes in protein kinase in liver. Glucagon administered in vivo to normal rats caused an increase in the activity ratio and a decrease in total protein kinase activity in liver. The changes are similar to those in diabetes. A decrease in the ratio of insulin to glucagon in diabetes may account for the changes in protein kinase observed.
