Relative Comparisons

Purpose:To compare dermal electrolyte loss between whole body and regional patch methods in women during 24-h.Methods:Dermal loss was collected in 6 healthy women mean age 27 ± 4 years, while consuming 936 mg/d sodium, 1764 mg/d potassium, 696 mg/d calcium, and 152 mg/d magnesium. Twenty-four hour whole body dermal loss was collected using cotton suits by a washdown procedure. Twenty-four hour patch loss was collected from 8 patches placed on the legs, arms, and back.Results:Dermal loss from whole body was 108 ± 110 mg/d sodium, 133 ± 87 mg/d potassium, 103 ± 22 mg/d calcium, and 35 ± 13 mg/d magnesium. Electrolyte content from the 8 patches was similar among sites and ranged from 1.01–1.41 mg/d sodium, 0.35–0.83 mg/d potassium, 1.0– 1.45 mg/d calcium, and 0.43–0.49 mg/d magnesium. Projections from patches to whole body by the ratio of body surface area appear to overestimate actual whole body losses by 3.2X for sodium and calcium, 3.6X for magnesium, and 1.3X for potassium.Conclusions:Regional patch methods are more appropriate for relative comparisons than for accurately determining total daily dermal electrolyte losses.

Direct Calorimetry

Aging is associated with an attenuated physiological ability to dissipate heat. However, it remains unclear if age-related impairments in heat dissipation only occur above a certain level of heat stress and whether this response is altered by aerobic fitness. Therefore, we examined changes in whole body evaporative heat loss (HE) as determined using whole body direct calorimetry in young ( n = 10; 21 ± 1 yr), untrained middle-aged ( n = 10; 48 ± 5 yr), and older ( n = 10; 65 ± 3 yr) males matched for body surface area. We also studied a group of trained middle-aged males ( n = 10; 49 ± 5 yr) matched for body surface area with all groups and for aerobic fitness with the young group. Participants performed intermittent aerobic exercise (30-min exercise bouts separated by 15-min rest) in the heat (40°C and 15% relative humidity) at progressively greater fixed rates of heat production equal to 300 (Ex1), 400 (Ex2), and 500 (Ex3) W. Results showed that HE was significantly lower in middle-aged untrained (Ex2: 426 ± 34; and Ex3: 497 ± 17 W) and older (Ex2: 424 ± 38; and Ex3: 485 ± 44 W) compared with young (Ex2: 472 ± 42; and Ex3: 558 ± 51 W) and middle-aged trained (474 ± 21; Ex3: 552 ± 23 W) males at the end of Ex2 and Ex3 ( P < 0.05). No differences among groups were observed during recovery. We conclude that impairments in HE in older and middle-aged untrained males occur at exercise-induced heat loads of ≥400 W when performed in a hot environment. These impairments in untrained middle-aged males can be minimized through regular aerobic exercise training.

AbstractTo investigate if serum 25-hydroxyvitamin D (25(OH)D) is related to the whole Body Surface Area (BSA), and to several other anthropometric and environmental factors.Serum 25(OH)D was determined in 489 apparently healthy subjects (346 women and 143 men, mean age 43.9 years) in April and May. From all subjects the following data were available: height, body weight, waist to hip ratio, BSA, BMI, environment of work (indoors vs. outdoors), habit of regularly sunbathing during previous summer(s), fear of sun, dwelling in city or village, and skin color.Approximately 43% of the participants had serum 25(OH)D levels between 10 and 20 ng/ml, 44% had values between 20.1 and 30 ng/ml, whereas about 5% had values below 10 ng/ml and only 9% had values above 30 ng/ml. There was a significant positive relationship between 25(OH)D, height and BSA, which was more pronounced for BSA in obese subjects even after adjustment for work outdoors and sunbathing during previous summer(s). Outdoor workers and sunbathers had higher 25(OH)D compared to indoor workers and non-sunbathers respectively. Men when compared to women had higher 25(OH)D regardless of BMI and this difference was apparently due to the fact that men were taller, had greater BSA, and worked more often outdoors.Height, whole BSA, gender, working outdoors and sunbathing in previous summer(s) proved to be significant determinants of serum 25(OH)D. Vitamin D status is higher in taller individuals with greater BSA, and in men when compared to women.

Purpose of this study was to compare the effectiveness of talcum, unguentum and paste of mangosteen peel extract standardized (Garcinnia mangostana Linn) against Ringworm Disease in vivo. This type of experimental research using completely randomized design. The research sample: male hamster 24 animals, divided 4 groups and 6 replications: a control group, were infected ringworm fungus (Trycophyton mentagophytes) but not given treatment (P0), the treatment group infected ringworm fungus and treated with talcum extract standardized mangosteen rind (P1) treatment group and the untreated ringworm fungus infected unguentum standardized extract of mangosteen peel (P2), a group that ringworm fungus infected and treated with a paste of mangosteen peel extract standardized (P3). Giving a fungal infection ringworm done once, then wait 1-2 weeks until the fungal infection spread to the whole body of experimental animals were then treated according to the treatment dose of 50% twice a day. Observation of wound healing, change in body surface area that has been infected with mildew, scab and reduction of area small dots such as rings and mushrooms are native examination conducted on the 5th, 10th and 15th. Results of the examination of the wound healing, change in body surface area that has been infected with mildew, scab and reduction of area small dots like ring diskoring and analyzed by Analysis of Variance (ANOVA). The results showed: the treatment group was given a fungal infection ringworm and treated with a paste of mangosteen peel extract standardized to 50% dose twice daily (P3) provide most excellent and effective than the group P2, P1 and P0 appears on the 15th day.
