    Notes: Abstract Energy dispersive X-ray fluorescence technique was employed to study the interactions of lead (50 and 100 mg/kg body wt) with K, Fe, Cu, Zn, Br and Rb in rat liver. Lead was administered orally to rats daily for dosage periods of 1 and 4 months (short and long terms). Hepatic Fe levels were found to increase significantly with the supplementation of low and high doses of lead for both the treatment periods, although the increase was more pronounced following long-term treatment. The levels of hepatic K, Cu and Br were seen to decrease significantly over both time intervals. Moreover, hepatic Rb contents were lowered with the short-term supplementation of low doses of lead. In contrast, Rb and Zn levels were increased when lead was administered for the longer period at both dose levels.

    Notes: Abstract In vitro micropropagation of holy basil (Ocimum sanctum L.), an Indian medicinal herb, has been accomplished on Murashige and Skoog (MS) medium utilizing young inflorescence explants. MS supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) or thidiazuron (TDZ) produced only non-morphogenetic callus. Direct multiple shoots differentiated within 2--3 weeks when explants were cultured on MS containing 6-benzyl aminopurine (BAP). Of the various levels of BAP tested, MS + BAP (1.0 mgl−1) produced the maximum number of shoots. Incorporation of indole-3-acetic acid (IAA) (0.05 mgl−1) along with BAP (1.0 mgl−1) in the culture medium showed a marked increase in the number of shoots. About 92% of the in vitro regenerated shoots rooted on MS hormone-free medium within 2--3 weeks of culture and 85% of the micropropagated plantlets could be successfully established in soil, where they grew normally.
