Monosodium L-glutamate (MSG) has been suggested to cause postprandial symptoms after the ingestion of Chinese or oriental meals. Therefore, we examined whether such symptoms could be elicited in Indonesians ingesting levels of MSG typically found in Indonesian cuisine. Healthy volunteers (n = 52) were treated with capsules of placebo or MSG (1.5 and 3.0 g/person) as part of a standardized Indonesian breakfast. The study used a rigorous, randomized, double-blind, crossover design. The occurrence of symptoms after MSG ingestion did not differ from that after consumption of the placebo.
The water contamination in one place can affect the other places located far fromthe source of pollution. One of the rivers that are polluted is Bengkulu river. One of thecauses of pollution in Bengkulu river that is coal waste originating from coal mine companyin the upstream of the river, which is still in service until now. The coal handling treatment ascrushing, grinding, washing, drying and low temperature combustion can cause any harmfulchemical substances like lead. Lead can get into the human body through the digestive tractabsorption or through the respiratory tract (inhalation) and skin absorption. One way ofdisposal of heavy metal elements from the body is to accumulate in the hair, so the hairanalysis is a good way to estimate the content of heavy metal elements in the body anddetermine its connection with hypertension. The purpose of this study is to determine thecontent of lead in a coal waste accumulates in hair of coal waste collectors society inBengkulu river associated with hypertension. This study is an analytic observational studywith cross sectional study design. The case that will be studied is about the accumulation ofhair lead of coal waste collectors society in Bengkulu river against hypertension. The studylocation is in Bengkulu river. Sample examination was conducted by Atomic AbsorptionSpectrophotometry (AAS) analytical methods, and then performed statistical tests todetermine its connection with hypertension. The result of this study showed, from 40respondents there were 14 respondents (35%) who had hair lead levels > 12μg/g sufferedfrom hypertension and 13 respondents (32.5%) who had hair lead levels > 12μg/g but did notsuffered from hypertension, and p(0.03)< 0.05 value which indicates a significant association.Significant association between the levels of lead in the hair of coal waste collectors society inBengkulu river with hypertension
Purpose: This research aimed to analyze the correlation between levels of cadmium level in blood and decreasing kidney function reviewed from ureum and creatinine levels in exhaust welders in Purbalingga Lor. Methods: This research used a cross sectional design. Samples were counted by using random sampling formula and there were 36 respondents chosen. 32 respondents participated in this research. Results: There was no correlation between the external variables (age, smoking habit, self hygiene, working period, the number of working hours per week, and use of the mask) and the independent variable (levels of cadmium). There was no correlation between independent variable (levels of cadmium) and dependent variables (levels of ureum and creatinine) on exhaust welders in Purbalingga Lor. Conclusions:This study contributes to the knowledge that levels of cadmium in the blood have no correlation on the levels of ureum and creatinine in kidneys of exhaust welding workers. This study recommends to develop research on other types of heavy metals that may potentially interfere with the health of welding workers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
