Blood lead levels of 253 Delhi children were estimated by dithizone method. In 82 (controls) children with no symptoms mean blood lead level was 9.6 micrograms/dl (+/- SD 6.8: median 10 micrograms); only 6 had high levels between 30-33 micrograms/dl. In 88 children with pica, the mean blood lead level was 23.0 micrograms/dl (+/- SD 13.82; median 17 micrograms) which was significantly higher than the control; 26 had high levels between 30-92 micrograms/dl. Sixteen children with pica and surma-use and 46 children suspected of lead poisoning showed lead level patterns like the pica group. However, 21 surma-using children without pica resembled the control group. Children with pica were significantly more anemic than the controls and showed higher prevalence of abdominal-neurological symptoms. Because, in India, blood lead cannot be estimated in most of the hospitals, it is suggested that children with severe pica, anemia, abdominal-neurological symptoms and exposure to surma or lead, be suspected of lead poisoning, kept in lead-free environment with corrected nutrition, and be given a short cautious therapeutic trial with oral penicillamine.

Some aspects of pharmacological profile of sodium curcuminate.

Rapid i.v. injection of sodium curcuminate (NaC) produced transient hypotension and bradycardia in anaesthetized dogs and cats which were not blocked by bilateral vagotomy, atropine, mepyramine or propranolol. In open-chest anaesthetized cats, decrease in blood pressure and heart rate was accompanied by simultaneous transient reductions in left ventricular systolic pressure, maximal rate of rise of left ventricular pressure and a concomitant increase in left ventricular end-diastolic pressure. It was concluded that the transient hypotensive effect of NaC is due to its myocardial depressant action. NaC exhibited negative inotropic and chronotropic effect on isolated perfused rabbit heart, an antispasmodic effect on smooth muscle of dog s intestine in vivo and of vas deferens of guinea-pig in vitro but no effect on the rectus abdominis muscle of frog or its response to cholinergic stimulation.
