The hypertension detection and follow-up program: a progress report.

The NHLBI-supported Hypertension Detection and Follow-Up Program (HDFP) is a community-based program designed to assess the value of early detection and vigorous treatment of persons with high blood pressure of varied severity. HDFP staff members have measured the blood pressures of 158,906 persons in their homes or work places in 14 communities across the United States. Of those persons, 10,940 were found to be hypertensive in a two-state screening process and were enrolled in the Program. Half were referred on a random basis to sources of care in the community, and half were invited to the special Stepped-Care clinics sponsored by the HDFP. These clinics, in a vigorous attempt to normalize blood pressure for all these hypertensive participants, stress intensive follow-up and special attention to achieve compliance with treatment. More than 80% under Stepped Care are continuing on therapy after 2 years, and three-fourths of these have achieved desired normal levels of pressure. The majority of hypertensives found in this Program have less severe elevations of blood pressure, and even among them reductions in blood pressure were substantial because of the vigorous follow-up and special attention to compliance. The HDFP is continuing its efforts to find to what extent sustained treatment of those with elevated blood pressure can reduce mortality or complications due to hypertension.

Brugia malayi in seven villages in South Kalimantan, Indonesia.

Seven villages in South Kalimantan were visited in 1971 and night peripheral blood smears from 2,764 people examined for microfilariae. Brugia malayi was found endemic in all villages with microfilarial rates of 12--46% (average 25%) and the median microfilarial density (MfD50) of 6 to 15 microfilariae per 20 microliter of blood. The microfilariae showed a typical subperiodic pattern. The disease was more common in males than females and the prevalence increased with age. Clinical manifestations of filariasis were found in 20% of 1,099 persons examined. Mansonia species are considered important vectors and cats important reservoir hosts. In addition to B. malayi, Dirofilaria repens and an unknown microfilaria were found in cats in the area and strains of the B. malayi and D. repens have been established in the laboratory.

Effects of swimming on dystrophic Syrian hamster heart.

Morphological and histopathological heart changes were determined for sixteen dystrophic Syrian hamsters (B10 14.6 strain) and sixteen normal hamsters. Eight animals were randomly assigned to each of the following groups: dystrophic swim (DYS-SWM), dystrophic sedentary (DSY-SED), normal swim (NOR-SWM), and normal sedentary (NOR-SED). The daily swimming program consisted of an initial 30-minute swim which was gradually extended to 60 minutes by the end of eight weeks. Weights up to 3% body weight were attached during swimming to increase the work load. Sedentary animals received no experimental treatment. Four animals in each group were sacrificed at 4 and 8 weeks after the initiation of treatments. In comparison with the two groups of sedentary animals, the NOR-SWM group had a greater heart weight/body weight ratio at both 4 and 8 weeks (P less than .05), while the DYS-SWM group had an increased ratio only at 8 weeks (P less than .05). Subjective histopathological evaluation of heart lesions showed that the DYS-SED group had many large areas of inflammatory reaction with infrequent diffuse areas of calcification. In contrast, the DYS-SWM group had fewer and smaller areas of inflammatory reaction with moderate amounts of calcification.

Parasitology survey and seroepidemiology of amoebiasis in South Kalimantan (Borneo), Indonesia.

A parasitology surevy was conducted among inhabitants of 7 villages in 3 regencies in South Kalimantan Province, Indonesia. A total of 2,169 stool specimens, 2,756 blood smears and 1,027 serum specimens were obtained, representing samples from approximately 10%, 12% and 5% of the population, respectively. One to 8 different intestinal parasitic infections were detected in 97% of the people. Those parasites most frequently found were Trichuris trichiura (83%), Ascaris lumbricoides (79%), and hookworm (65%), followed by Entamoeba coli (37%), Endolimaxnana (12%), Entamoeba histolytica (12%), Iodamoeba bütschlii (11%), Giardia lamblia (5%), Entamoeba hartmanni (2%), Chilomastix mesnili (2%). Other parasites found were Enterobius vermicularis, Strongyloides stercoralis, Capillaria sp., Echinostoma sp., Hymenolepis diminuta, and Trichomonas hominis. Giardia lamblia was found more often in younger people and Entamoeba coli, Iodamoeba bütschlii and hookworm in the older age group. Ascaris lumbricoides occurred more frequently in females, and hookworm in males. Plasmodium vivax and Plasmodium falciparum were found in the blood smears of 4.4% of the people, mostly in the younger age groups. Seroepidemiological studies on amoebiasis were done by use of the indirect hemagglutination test with antigens prepared from the HK9 strain of Entamoeba histolytica maintained in axenic cultures. The frequency distribution of the reciprocal antibody titers showed a bimodal distribution with 34% of the population demonstrating positive reactions at titers of 1:128 or greater.
