Iodine content in urine samples among Malays and aborigines.

A study was conducted to compare the urinary iodine concentrations in populations from Pahang, Central Malaysia, with those in the capital city Kuala Lumpur, and to compare those of Malays from villages at Batu Talam, Batu Malim, FELDA Sungai Koyan and Hulu Sungai with neighboring aboriginal settlements at Lanai and Buntu. Two hundred and forty urine samples were collected randomly among the population (male 1 1 1 and female 129). The urinary iodine concentrations, measured by the ashing method, among Malays were as follows: Batu Talam 1.1-7.6 micrograms/dl, Batu Malim 1.4-6.6 micrograms/dl, FELDA Sungai Koyan 0.5-6.9 micrograms/dl and Hulu Sungai 0.6-9.9 micrograms/dl. Among aborigines, the urinary iodine levels were 0.1-2.9 micrograms/dl in Lanai and 1.7-6.5 micrograms/dl in Buntu. There was a significant difference in the levels of urinary iodine with regard to gender, but not regarding age. The aborigines had significantly lower iodine levels than Malays (P < 0.001). This difference was also significant with regard to location. The urinary iodine content in Kuala Lumpur was the highest and that in the aboriginal Lanai village was the lowest. Thus, the study showed that the levels of iodine in the urine were influenced by ethnicity and geographic location.

Thyroid function and pubertal development in malnutrition.

Thyroid function and pubertal development of aborigines (Orang Asli) and Malays at different socioeconomic strata were assessed among 1136 subjects aged 7 years and above. Anthropometric measurements, goitre and pubertal staging were done. Serum thyroxine (T4), triiodothyronine (T3) and growth hormone were measured using radioimmunoassays (RIA) and serum thyroid stimulating hormone (TSH) by immunoradiometric assays (IRMA). It was found that serum T3 in children was significantly higher in Malays from rural areas, girls and children aged less than 13 years. However, in adults, T3 was significantly associated with anthropometric indices. On the contrary, serum T4 levels were higher among children from urban areas. In adults, serum T4 levels were significantly related to nutritional status and they increased according to the levels of social development, being lowest in remote areas and highest in urban areas. However, serum TSH levels were significantly higher in Orang Asli at all ages and among malnourished children. By using multiple regression, apart from age, gender and ethnicity, nutritional status was a significant predictor for T3 levels in children and adults. Presence of goitre was an important factor which determined the T4 levels in children and adults after controlling for other factors. It was also a predictor for TSH levels in children but not in adults. Fasting serum growth hormone (GH) levels were significantly higher among less privileged groups and decreased according to social development. Serum growth hormone was negatively correlated with anthropometric indices and had a significant association with malnutrition.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence of NIDDM and impaired glucose tolerance in aborigines and Malays in Malaysia and their relationship to sociodemographic, health, and nutritional factors.

OBJECTIVE: To determine the prevalence of diabetes mellitus and IGT in different ethnic groups living in the same physical environment and to find their relationship to nutritional status and dietary intake. RESEARCH DESIGN AND METHODS: The study was conducted among Malays and Orang Asli in six rural and urban locations in Malaysia. OGTTs were performed on 706 adult subjects > or = 18 yr of age. WHO criteria were used for diagnosing diabetes mellitus and IGT. RESULTS: The overall prevalence of diabetes mellitus and IGT among Orang Asli was 0.3 and 4.4% compared with 4.7 and 11.3%, respectively, among Malays. This increased prevalence of glucose intolerance among Malays was associated with higher levels of social development. Among rural Malays, the crude prevalence of diabetes in a traditional village was 2.8% and in the land scheme was 6.7%, whereas urban Malays had a prevalence of 8.2%. In contrast, the prevalence of IGT (10.5-14.8%) was higher among rural Malays, compared with 9.6% among urban Malays. Ethnic group, > or = 40 yr of age, an income > M$250, fewer daily activity, and obesity were associated with a higher prevalence of diabetes. CONCLUSIONS: Diabetes mellitus and IGT, which were more common among Malays than Orang Asli, were associated with more affluent life-styles and modernization.

Socioeconomic, social behaviour and dietary patterns among Malaysian aborigines and rural native Malays.

The socioeconomic, social behaviour and dietary pattern of 100 Aborigines and Malays, aged 7 years and above from Kuala Pangsoon, Selangor Malaysia were studied by using pretested questionnaires. The individual's dietary intake was estimated using 24 hour recall for 3 days within one week which was chosen at random. The household's food consumption pattern was evaluated using food frequency questionnaires. There was no difference in the total income per month for both communities, as well as the educational attainment of the head of household and property ownership. The proportion of smokers among the Aborigines and the Malays was almost similar (33%) but the percentage of heavy smokers was higher among Aborigines compared to Malays. One third of the Aborigines regularly consume alcohol. The main energy source for both communities was rice, sugar and cooking oil whilst fish and eggs were the main sources of protein. More than 50% of the Aborigines take tapioca or tapioca leaves at least once a week compared to less than 20% among the Malays. There was no significant different in the intake of energy, protein and carbohydrate between the groups. However, the Aborigines take less fats and iron compared to the Malays. The difference in terms of smoking, drinking habit and dietary intake may determine the distribution of disease in both communities.

Lipase productivity of a lipolytic strain of Thermoactinomyces vulgaris.

An attempt was made to evaluate the lipase productivity by Thermoactinomyces vulgaris with various nutritional and environmental factors. Results suggest optimum conditions for production, viz. age of inoculum 18 hours, 55 degrees C, pH 6.8, 0.2% yeast extract, specific substrates, and shaken cultures incubated for 24--36 hours. Lipases are induced by corn oil in presence of yeast extract or of certain substitutes; starch could replace these at 55 degrees C. A suggestion is given of a regulatory system of lipase synthesis, involving the supply of starch to initiate growth, allowing induction of lipase by the inductive substrate.

Identity and lipase activity of an isolate of Thermoactinomyces vulgaris.

An actinomycete with thermophilic nature and strong lipolytic activity was isolated by enrichment from an Egyptian soil. It proved to be Thermoactinomyces vulgaris. Variabilities justifying Adansonian systematics were reported and discussed. The potential relation of an occasional drop in successfully resumed activity to an auto-inhibition phenomenon has been notified. Optimum conditions for the activity of the extracellular lipase(s), including stability, suggest the practical importance of the enzyme(s) in the growth filtrates.

Iodine deficiency disorders: a public health challenge in developing countries.

Iodine as a trace element is an essential nutrient for human growth and development. Its potential impact on manpower development in third world countries are of special concern, primarily due to iodine deficiency disorders (IDD) such as goiter, hypothyroidism, and cretinism. IDD of mild to moderate severity are still found in Malaysia. The prevalence ranges from almost zero in many developed urban areas to more than 90% in some rural parts of Malaysia, especially in Sabah and Sarawak. The endemias were associated with low urinary excretion of iodine among the population, indicating poor iodine intake and low iodine content in the environment. Water and salt iodination strategies are being planned to eradicate the disease by the year 2000.

[The effect of contrast baths on the hemostatic function of patients with ischemic heart disease].

Contrast baths effects on hemostasis were studied in 72 patients with postinfarction cardiosclerosis and stable angina pectoris. Hemostasis was assessed by recalcification time, blood plasma tolerance to heparin, fibrinolytic activity, functional activity of antithrombin, soluble fibrin-monomeric complex, platelet count and aggregation. The results were compared to those in patients exposed to laser irradiation. Hydrotherapy with contrast baths was hemostatically effective in 70.9% of patients. Blood coagulation and platelet aggregation improved, the risk of intravascular microthrombogenesis diminished. Contrast baths had more pronounced beneficial effects on coagulation in ischemic heart disease of NYHA functional class II.
