[Doxazosin (alpha 1-adrenoreceptor antagonist) used in primary hypertension and it's beneficial effect on lipid metabolism].

The aim of the study was to investigate the effect of a new selective alpha 1-adrenoreceptor blocker doxazosin on blood pressure, serum lipids and lipoproteins in patients with essential hypertension. The study was done in 32 out-patients with mild-to-moderate hypertension (22 men and 10 women, mean age 45.6 +/- 10.1). After 2-week placebo period the patients were given doxazosin in increasing doses from 1 to 8 mg daily for 6 to 14 weeks (mean daily dose 2.24 +/- 1.6 mg). Twenty-nine patients completed the study. The active treatment caused highly significant drop in systolic and diastolic blood pressure both in supine and standing positions. No orthostatic hypertension was noted. There was also a statistically significant decrease in serum total cholesterol, VLDL-cholesterol, and triglyceride levels and increase in the positive prognostic lipid indicators. HDL3-cholesterol and apolipoprotein AI levels as well as HDL/total cholesterol ratio. Accordingly, the statistically significant decrease of the so called atherogenic index was noted. The drug was well tolerated and only one patient dropped from the study because of side effects. The authors conclude that doxazosin appears to be an effective and well tolerated antihypertensive drug with a favorable effect on lipid metabolism. It may be particularly useful in hypertensive patients with coexisting lipid abnormalities.

Molecular biology: an overview.

An overview of molecular biology is presented for the practicing surgeon. Definitions of the constructs and activity of DNA, RNA, and protein synthesis are defined. These principles are illustrated in their use in recombinant DNA technologies. A glossary is provided for the terms utilized.

Molecular mechanisms of tumor formation.

DNA is the fundamental guide for the cell's processes. The alterations in DNA that can lead to abnormal or absent proteins and the role of chromosomal alterations in changing the function of the DNA are reviewed. The role of viruses in derailing a cell's normal functions, the major mechanisms of oncogene action, and tumor suppressor genes are also discussed.

Dietary sodium intake of infants fed commercially prepared baby food and table food.

Sodium intake of infants varies widely with the type of food consumed. However, few reports are available describing the nutrients, including sodium values, of dietary intakes of infants receiving supplemental foods. The purpose of this study was to determine the sodium, energy, and nutrient values of diets for infants from low-income families participating in the WIC program. The sample consisted of 306 infants, aged 4 through 7 months, who were seen in well-child clinics. Approximately 200 of the infants were reportedly fed commercially prepared baby food as the only solid food; 55 received 50% or more of their energy from table foods. The dietary intakes of infants receiving supplemental foods and consuming commercially prepared baby foods included significantly less sodium than the intakes of infants fed primarily table foods. As a group, all infants met the RDAs for most nutrients but had higher sodium values than reported by other researchers. The group of infants for whom consumption of table foods was reported had values above the acceptable range for sodium primarily because the caregivers failed to provide low-sodium, nutrient-dense, supplemental foods in the quantities prescribed but instead substituted sodium-dense meat and vegetable products.
