Placental transfer of pesticides in humans.

Transfer of organochlorine pesticides from mother to fetus has been studied in 100 women. The concentrations of organochlorine pesticides were examined in maternal blood, placenta, and umbilical cord blood of the same mother/child pair. Residue levels of dichlorodiphenyl trichloro ethane (DDT) and its metabolites, isomers of benzene, hexachloride (BHC) and aldrin were detected in all the samples analyzed, indicating their transfer from mother to the fetus. A correlation was found to exist between the pesticide concentration and age, dietetic habits and area of residence of pregnant women.

Chlorinated hydrocarbon pesticides in blood of newborn babies in India.

Umbilical cord blood collected during labor of 100 Indian women was analyzed for organochlorine pesticides by gas-liquid chromatography with electron-capture detection. Significant levels of p,p'-DDT and its metabolites, p,p'-TDE and p,p'-DDE, as well as alpha-, beta-, and gamma-isomers of BHC were estimated. Residues in the neonatal blood were related to age, dietetic habits, and area of residence of the mothers. The study highlights the extent of placental transfer of the body burden of toxic chemicals from the mother to the fetus.

Isaptent--a new cervical dilator.

A new cervical dilator, Isaptent, was prepared from granulated Plantago ovata (Isapgol) seed husk. It was evaluated in a multicentric clinical trial for dilatation of the cervix in subjects opting for medical termination of pregnancy. The trial covered 804 women in over 21 centres in different parts of the country. The cases were between 15 to 45 years of age, 0 to 10 parity with a gestation period of 8 to 24 weeks. A single tent was used in 750 subjects and satisfactory dilatation was achieved in 94% of the cases. The cervical dilatation bore no relationship to age, parity and gestation period of the subjects. The tent provided self-lubrication, caused no apparent damage to the cervix and the vaginal flora remained unchanged in the randomly selected subjects in whom bacteriologic studies were performed. The outcome of the clinical trial and advantages of Isaptent over the other procedures used for cervical dilatation are discussed.

Role of chlorinated hydrocarbon pesticides in abortions and premature labour.

Premature labour and abortion possibly due to the high concentration of organochlorine pesticides have been investigated. Considerably higher amounts of organochlorine pesticide residues have been detected by gas liquid chromatography in the circulating blood and placental tissue of the women undergoing abortion or premature labour as compared with pregnant women in full term labour. The differences are highly significant for all pesticides estimated.

Organochlorine pesticides in specimens from women undergoing spontaneous abortion, premature of full-term delivery.

Organochlorine insecticides (BHC, aldrin, p,p'-DDE, p,p'-DDD, p,p'-DDT) were measured in the blood, placenta and fetus of women experiencing spontaneous abortions, preterm labor or full-term labor using an electron-capture gas chromatographic method. The following trend was found for insecticide concentrations in each of the specimens tested: spontaneous abortions greater than preterm greater than full-term. One conclusion of this work is that the organochlorine insecticides act as antagonists to pregnancy. A plausible explanation for the facilitory role of organochlorine insecticides in the initiation of preterm labor/abortion is hypothesized.
