Effects of infusion of some prostaglandins in essential fatty acid-deficient and normal rats.

Infusion of 1 mg/kg per day of prostaglandin E(1) (PGE(1)) for 2 and 7 wk failed to correct the dermal signs of essential fatty acid (EFA) deficiency in rats despite the known conversion of EFA to certain prostaglandins. PGE(1) caused no significant changes in serum cholesterol, triglycerides, or phospholipids or in liver neutral lipids in EFA-deficient or normal rats. In normal rats epinephrine-induced lipolysis was greater in fat pads from infused than from untreated rats. The effect on epinephrine-induced lipolysis was greater after the 7 wk infusion than after the 2 wk infusion. The 7 wk infusion also lowered plasma free fatty acid (FFA) concentrations. Infusion of PGE(2) and PGF(2alpha) in combination for 4 wk had no significant effect on either dermal signs of EFA deficiency, lipolysis, or plasma FFA concentrations.

High fertility among Indochinese refugees.

From 1975 to 1988, nearly 900,000 Indochinese refugees were resettled in the United States. This paper examines patterns of fertility among these refugees from Cambodia, Laos, and Vietnam who have exhibited high levels of reproduction since their arrival. Data are drawn from sample surveys in San Diego and San Francisco, CA. Fertility levels were found to exceed five children per ever-married woman, a level that is consistent with perceptions of ideal family size in the homeland. Fertility levels were significantly higher among rural second-wave refugees than in the more urban first-wave groups. One explanation for the high fertility is that couples have migrated from areas where fertility is high, and they have not yet adapted their reproductive behavior to the low fertility environment of the United States. This possibility is reinforced by a general gender preference for boys and exacerbated by the fact that, while a majority of women are aware of methods of fertility control, access is still limited by cultural and financial barriers, and the motivation to use family planning still appears to be relatively low. The data suggest that this refugee population will continue to put pressure on maternal and child health resources, and that continued residence in the United States could lead to desires to limit family size, thus increasing demand for methods of fertility control.
