IPU 94) was grown under controlled sand culture at five levels of Zn supply ranging from 0.01 to 10 μmol/L. Leaves of 60 d old plants were examined for Zn concentration and activities of fructose 1,6 biphosphate aldolase, carbonic anhydrase, total superoxide dismutase, Cu-Zn SOD, acid phosphatase and ribonuclease, which have been shown to be activated/inhibited by Zn deficiency. Sub-optimal supply of Zn decreased the activities of FBPAse, CA, total SOD and Cu-Zn SOD and increased the activities of APase and RNAse. Activities of the Zn enzymes CA and Cu-Zn SOD, are highly correlated with Zn supply, and suitable as indicators of Zn nutrient status of plants. Activation of APase and RNAse by other micronutrient deficiencies and stress conditions does not favour their use as indicators of Zn nutrient stress.

In this three stage crossover trial forty five uncooperative ASA type-1 children, who required dental treatment, were randomly assigned to receive one of the three drugs/combination by IN route during three subsequent visits. The efficacy and safety of the agents were assessed by overall success rate and by monitoring of vital signs, respectively. The onset of sedation was rapid with K as compared to M and MK. The difference was statistically significant (P < 0.01) between K and M. The overall success rate was 89% with K, MK was 84% and 69% with M. The difference between the overall success rates of K and M was statistically significant (P < 0.01). Vital signs were within physiological limits and there were no significant adverse effects with any medication. M, K and MK are safe and effective by IN route to produce moderate sedation for providing dental care to pediatric dental patients who have been otherwise indicated for treatment under general anesthesia.

DPU-88-31) grown under deficient and excess supply of Zn. Plant grown with Zn supply ranging from 0.01 to 10.0 μM under glasshouse conditions showed optimal growth and biomass yield at 1.0 μM Zn supply. Deficient (0.001 and 0.01 μM) as well as excess (2.0 and 10.0 μM) supply of Zn decreased the concentrations of chlorophyll, carotenoids, and nonprotein thiols and increased that of ascorbate. The activity of superoxide dismutase and carbonic anhydrase was decreased at deficient levels and increased with increase in Zn supply up to 10 μM. At both stages of growth, the activities of antioxidant enzymes, such as catalase and ascorbate peroxidase, were decreased, whereas the activities of glutathione reductase and peroxidase were increased at both deficient and excess supply of Zn. An accumulation of hydrogen peroxide and thiobarbituric acid-reactive substances was observed in Zn-stressed leaves, indicating oxidative damage. Different responses to deficient and excess supply of Zn were observed in the production of oxidative damage.

DPL 15) and the extent to which the Zn requirement for reproduction can be met through supplementation of Zn at the time of initiation of the reproductive phase have been investigated.

The objective of this study was to evaluate the efficacy of four analgo-sedative combinations- midazolam plus ketamine (MK), midazolam plus tramadol (MT), promethazine plus tramadol (PT) and promethazine plus ketamine (PK) in facilitating dental treatment of uncooperative children. Thirty six uncooperative ASA type I children who required extensive dental treatment were randomly assigned to receive one of the four analgo-sedative combinations during each visit. A 4-stage cross-over design was adopted so that each child received all the four combinations. Safety was monitored through vital signs and side effects. The overall success was 81% with MK, 69% for PK, 67% for MT and 42% for PT and the difference between the success rates of these agents was statistically significant (p < 0.001). The required dental treatment could be successfully completed at least during 3 sessions in 23 children (62.2%). Segmental dental treatment under analgo-sedation can be considered as a viable alternative before considering patients for dental management under GA. MK and MT were found to be safe and effective for sedating pediatric dental patients.
