농약(農藥)이 토양(土壤)에 흡착(吸着)되는 현상(現象)을 이론적(理論的)으로 구명(究明)하기 위(爲)해 물리화학(物理化學)에서 쓰여온 분배법칙(分配法則)을 적용(適用)하여 다음과 같은 결과(結果)를 얻었다. 1) 토양(土壤)에 흡착(吸着)되는 농약(農藥)의 양(量)은 토양수분(土壤水分) 함량(含量)과 역비례(逆比例) 관계(關係)에 있다. 2) 토양수분함량(土壤水分含量)이 같은 경우 농약(農藥)의 흡착량(吸着量)은 분배율(分配率)(Kd)과 비례(比例)한다. 3) 분배율(分配率)이 큰 토양(土壤)일수록 토양수분(土壤水分)이 흡착(吸着)에 미치는 영향(影響)이 적다. The application of the Distribution Law to soil-pesticide systems yielded the following empirical implications : 1) The amount of the pesticide adsorbed by a soil is negatively proportional to the soil water content. 2) At a given soil water content the amount adsorbed is proportional to the Kd of the soil. 3) The effect of soil water content on the amount of the pesticide adsorbed diminishes with increasing magnitude of the Kd.

The purpose of this study was to investigate the alteration of plasma anti-inflammatory cytokines, including interleukin-6 (IL-6), soluble TNF receptor (sTNFr), IL-10, and interleukin-1 receptor antagonist (IL-1ra), during different types of running exercise(level and downhill running). Seven healthy male college students completed two different exercise trials on separate occasions: (1) level treadmill running at 75% VO₂max for 30 min; (2) downhill treadmill running (?12% gradient) at 75% VO₂max for 30 min. Blood was sampled before, immediately after, and 1 h, 4 h, 24 h after exercise. Visual analog scale (VAS) score was obtained at the same time point. Plasma was analyzed for cytokines and creatine kinase (CK) activity. The plasma concentrations of IL-6 increased significantly (P<0.05) after exercise in both trials but there was a difference in pattern of change between trials. CK activity and VAS score increased significantly after the downhill running but not in level running trial. IL-10, as like IL-6, increased significantly (P<0.05 or P<0.01) after downhill running but not in level running. There was no significant alteration of sTNFr and IL-1ra in both running trials. In conclusion, there was a different pattern in response of exercise-induced anti-inflammatory cytokines such as IL-6 and IL-10 between running types (level and downhill).

The sweat volume of indirectly activated(AXR) and directly activated(DIR) of sweating that occurs in the aerobic exercise-trained as compared to the sedentary subjects has been attributed to differences in the peripheral sweating mechanisms, although such mechanisms have not been completely investigated in comparative terms. The aim of this study was to investigate quantitatively the peripheral sudomotor adaptive mechanisms attributed for AXR and DIR sweating that is found in the aerobic exercise- trained runner(Trainee) in contrast to the health control(HC) subjects. QSART by 2 mA for 5 min of 10% ACh were applied to determine AXR by nicotinic receptor mediated sweating activity(axon reflex-mediated) and DIR by muscarinic receptor mediated sweating activity sweating during ACh iontophoresis. The sweat volumes of AXR(1), AXR(2) and DIR were higher in the aerobic exercise-trained Trainees as compared to those for the sedentary subjects. Furthermore, number of activated sweat gland density was higher in the aerobic exercise-trained Trainees as compared to sedentary subjects(p<0.001). The activated single sweat gland output was higher in the aerobic-trained Trainees as compared to the output for the sedentary subjects(p<0.001). These findings suggest that aerobic exercise-trained Trainees had higher sweat volume due to the combinations of a higher sweat gland output per activated sweat gland and more increased density of activated sweat gland.

Interleukin-8 (IL-8) is an inflammatory cytokine that acts as a chemokine on neutrophils. Increase of neutrophils and IL-8 induced by exercise. This study was designed to investigate the expression of interleukin-8 (IL-8) in plasma at resting and after acute intensive exercise in trained tennis players (Trained G) and untrained normal controls (Control G). All subjects underwent treadmill running for 30 min at 80% intensity of VO2max. Blood was drawn from peripheral vein for analyses. We analyzed the expression of mRNA and protein of IL-8 and evaluated the correlation between the number of neutrophils and plasma IL-8 level. Expressions of mRNA and protein of IL-8 were markedly higher in the Trained G as compared with the Control G at immediately after exercise, but not at before exercise, 30min and 120min after exercise). Except immediately after exercise, there was no correlation between the number of neutrophils and the plasma IL-8 concentration in both groups. Higher induced IL-8 after exercise in athletes may be caused by the adaptation to exercise training.

This study aimed to examine the effect of Oligonol intake on leukocytes, serum heat shock protein 70 (HSP70), and body temperature after heat stress. Subjects were male college tennis athletes. All subjects participated in two repeated experiments with one week interval. During the 30 min intermittent half-body immersion, subjects were given 500 water with or without Oligonol(100 mg). Blood samples were taken from antecubital vein and differential leukocytes were counted. Serum HSP70 protein was analyzed by commercial ELISA kit. Skin and tympanic temperatures were measured and mean body temperatures were calculated. After half-body immersion, leukocytes increased significantly(p <0.05). But there were no significant changes of neutrophils and monocytes in both trials(with or without Oligonol). In the case of Oligonol, lymphocytes kept increased during recovery period(p <0.01, p <0.05, respectively). Serum protein level of HSP70 did not changed after immersion, but it decreased 60 min after immersion with Oligonol(p <0.05). Tympanic temperatures in Oligonol trial was maintained at lower degree overall recovery period compared with placebo trial(p <0.05, p <0.05, respectively). In conclusion, Oligonol intake had a benefit of reducing body temperature and accumulation of serum HSP70 protein, and of improving lymphocytes immune function after heat stress in tennis athletes.

This study examined the effect of supplementary selenium on leukocytes and heat shock protein (HSP) 70 expression in serum during half-body immersion. The subjects were male college tennis athletes. All subjects participated in two repeated experiments with a 1 week interval. During the 30 min intermittent half-body immersion subjects were given 500 mL of water with or without selenium (100 ㎍). Blood samples were taken from the antecubital vein and differential counts were made. Serum HSP70 protein was analyzed using a commercial ELISA kit. After half-body immersion leukocytes and lymphocytes increased significantly but neutrophils decreased significantly in both trials (with or without selenium). Selenium supplementation compared with placebo decreased levels of leukocytes neutrophils and monocytes but not lymphocytes to the resting level or below 60 min after immersion. Only lymphocytes continued to increase in both trials during the recovery period. Serum HSP70 protein level did not change after immersion but it decreased 60 min after immersion with the administration of selenium. In conclusion supplementary selenium reduced the systemic immune response and serum HSP70 protein accumulation after half-body immersion.

Tropical inhabitants are able to tolerate heat through permanent residence hot and often humid tropical climate, to clarify the peripheral mechanisms of the thermal sweating in pre-post exposure by sweating responses to acetylcholine (ACh), a primary neurotransmitte of the sudomotor functions were healthy subjects (n=8). ACh was iontophoretically 10% iontophoresis administered on the inner forearm skin. Directly activated and axon reflex-mediated sweat responses were evaluated by quantitative sudomotor axon reflex test. The AXR sweat onset-time (axon reflex) was 1.62±0.82 min and 1.24±0.62 min in human subjects by pre-post exposure, respectively (P<0.001). The AXR(1) sweat volume (axon reflex) was 1.25±0.75 ㎎/㎠ and 2.08±0.85 ㎎/㎠ in human subjects by pre-post exposure, respectively (P<0.001). The AXR (2) sweat volume (axon reflex) was 2.03±0.65 ㎎/㎠ and 3.05±0.72 ㎎/㎠ in human subjects by pre-post exposure, respectively (P<0.001). The DIR sweat volume (directly activated) was 4.96±1.38 ㎎/㎠ and 5.68±1.27 ㎎/㎠ in human subjects by pre-post exposure, respectively (P<0.001). Activated sweat volume in the sudomotor functions was higher the output for the post-exposure than the output for the output pre-exposure. It was concluded that the post-exposure had the higher sweat output due to the combination of the higher sweat volume and the shorter of onset time. In conclusion, higher sudomotor responses to ACh receptors are indicative of accelerated sympathetic nerve responsiveness to ACh sensitivity by exposure environmental condition.
