    Assessing the accuracy of respiratory rates at different counting periods and methods
    (1996-01-01) Khin Myat Tun; Phyu Phyu Aung; Thida Kyaw; Khin Saw Aye; Thein Shwe; Le Le Win; Soe Aung
    The respiratory rates of 198 children (aged 2-59 months) suffering from acute respiratory infections (ARI) were monitored by observation, palpation and auscultation (Gold standard). Two 30-second and one 60-second counts were obtained. The difference among respiratory rate counts determined simultaneously by observation, palpation and auscultation in relation to their mean count was analyzed for 60-second counting period, 30 plus 30-second period and 30-second doubled. The variability among the different counting methods and counting periods was not significantly different whether the children were feeding, sleeping, resting and awake or awake but not resting. The data from the study suggest that respiratory rate counting either by observation or palpation are similar in accuracy and one minute's counting either at a stretch or 30-second doubled or two blocks of 30-second intervals are also similarly accurate.

    Assessment of the erythrocyte protoporphyrin test for screening of iron deficiency anaemia
    (1994-12-01) Khin Myint Myint Kyaw; Khin Myat Tun; Than Than Lwin; Tin Moe Moe; Phyu Phyu Aung; Khin Saw Aye; Thida Kyaw; Tin Nu Swe
    A total of 84 apparently healthy children between ages of 1-12 years were screened for iron deficiency with the erythrocyte protoporphyrin (EP) test. Serum iron, total iron binding capacity in serum, percent transferrin saturation, haematocrit and haemoglobin values were also determined together with the screening test. Comparing the relationship between EP and percent transferrin saturation, using a percent transferrin saturation value < 10 percent as the criterion of iron deficiency, the optimal cut off limit for the EP test appears to be 80 ug/dl of rbcs. At this level, this screening test showed a sensitivity of 74 percent and specificity of 95 percent and the positive and negative predictive values were 82 percent and 93 percent respectively. thus EP assay which is less expensive and easy to perform can be used as a screening test for the detection of iron deficiency.

    Comparative study on the dietary behaviour and serum/urine electrolyte levels of hypertensive males in thonegwa township
    (2000-01-01) Theingi Thwin; Phyu Phyu Aung; Han Win; Tin Nu Swe
    This study was a cross-sectional, hospital based, comparative study. It was conducted on 31 pairs of the hypertensive and apparently health males between 25-59 years. At the time of hospital admission, dietary bahaviour was interviewed by menas of the structured questionnaires. The blood pressure was measured at the time of admission and discharge. Serum sodium and potassium levels and urinary excretion of them were also measured. Family history of hypertension was strongly associated with the hypertensives (P<0.05). Hypertensive subjects consumed palm oil two times (odd ratio=2.2) more than normotensive subjects. A significant association of hypertension and daily consumption of soda rich snacks was found in the cases (p<0.05). The mean serum sodium level of the cases was significantly higer than that of the controls (P<0.03) but 24 hour urinary sodium excretion of them was not significantly lower. Thus, increased salt consumption with impaired renal handling of sodium homeostasis would be responsible for higher prevalence of hypertension in Thonegwa Township.

Tthe mean serum sodium level of the cases was significantly higher than that of the controls (p<0.03) but 24 hour urinary sodium excretion of them was not significantly lower. Thus, increased salt consumption with imparired renal handling of sodium homeostasis would be responsible for higher prevalence of hypertension in Thonegwa Township.

    The effect of cigarette smoking on nasal mucociliary activity
    (1991-04-01) Maung Maung Cho; Phyu Phyu Aung; Tin Tun
    Nasal mucociliary transport rates of healthy twenty male non-smokers and twenty cigarette smokers (20-39 years) were measured using Saccharin Crystal Technique by Proctor (1973). The mean nasal mucociliary transport rate of non-smokers was found to be 10.17 mm/min. with a range of 8.78 to 12.22 mm/min. and that of cigarette smokers was 7.95 mm/min ranging from 7.04 mm/min. Significant decrease (p<0.0010 in nasal mucociliary transport rate was observed in cigarette smokers.

    Glycaemic indices if three commonly eaten varieties of Myanmar Banana
    (2002-12-01) Tin Khine Myint; Theingi Thwin; Phyu Phyu Aung; Moh Moh Hlaing; Theingi Win Myat; Myint Myint Khine; Htike Htike Soe; Hnin Nu Htwe; Thandar Shwe
    In order to provide information for the nutritional management of diabetes mellitus, glycaemic indices (GI) of three varieties of banana commonly eaten in Myanmar were determined using twelve healty women volunteers with normalglucose tolerance. After an 8-10 hour overnight fast, the subjects consumed one kind of selected banana in amount equivalent to 50 g available carbohydrate portion {~ three and a half pieces of Phee-Kyan (189 g); ~four and a half pieces of Rakhine (165 g)~~ three pieces of Thee-hmwe (yellow) (192 g)}. After a week interval, GI was determined for another kind of banana. Venous blood samples were collected and immediately analyzed for plasma glucose by glucose oxidase method.GIs of Myanmar bananas (mean -+ S.E.M) were 51.7 -+ 7.69 percent for Rakhine, 55.29 -+ 5.66 for Phee-Kyan and 63.73 -+ 8.46 for Thee-hmwe (yellow). They were lower than GI of commonly eaten Myanmar rice, Pawsun. Banana also contains vitamins A and C which were not provided by cooked polished rice. Furthermore, banana hasa higher calcium and fibre content. Therefore, all three varieties of Myanamr banana can be recommended as a source of complex carbohydrate with low or moderateGI for diabetic diet

    Occupational exposure to tobacco dust:1. Effects on the respiratory system
    (1992-12-01) Phyu Phyu Aung; Phone Saing; Maung Maung Cho; Htay Htay; Kyi Kyi May
    Four hundred and seventy six workers who are exposed to tobacco dust and 112 nonexposed workers from the Cigarette Factory No. (1), Yangon were interviewed for respiratory symptoms and occupational history. General clinical examination was also done and recorded. Anthropometric measurements (height and weight) were taken and ventilatory functions in the form of forced vital capacity (FVC), forced expiratory volume in one second (FEV 1.0), and forced expiratory flow (FEF 25-75

    Urinary mercury excretion in Myanmar workers occupationally exposed to metallic mercury vapour
    (1991-12-01) Phyu Phyu Aung; Phone Saing; Soe Tint; Tin Htun
    Urinary excretion of mercury was determined in 32 workers of Chemical plant of No. (1) Pulp and Paper Mill in Sittaung. For comparison, it was also measured in 10 Clerical Staff (nonexposed) of the said factory and 10 Technician Grade I students of Health Department. Signs and symptoms of chronic metallic mercury poisoning were looked for in all subjects. The air concentration of mercury vapour at different times of the working hours in the Chlorine PLant was measured. The mean + or - SD urinary mercury excretion was significantly higher in exposed workers 59.22+ or -22.44 ugm/L than non exposed workers of the factory (29.3+ or -8.64) (p <0.001). Comparison of the mean + or - SD urinary mercury levels of the nonexposed workers of the factory and technician students (19.4+ or -8.59) indicated that the former had significantly higher mercury excretion (p < 0.001). There was an increasing trend of mercury excretion with increased duration of exposure (r = 0.54; p <0.05). Signs and symptoms of chronic mercury poisoning were not found in any subject. The concentration of mercury vapour in Chlorine Plant during the working hours was found to 0.1 to 0.25 mgm/m of air (2 to 5 times TLV).
