This study was conducted to investigate the effect of weight control by use of commercial formula diet and nutrition education on 36 obese women over a period of 6 months. During the study it motivated ways for women to control their weight and improve their health, thus analyzing variables that influence weight control. To help weight control, for the first 3 weeks, along with 1 regular mea, 2-3 liquid formula diets of 135㎉ per pack a day were provided within the 1,200-800㎉ range. For 6 months since then, all 3 meals were taken regularly and it was recommended that energy which is 500㎉ less than energy requirement be taken. To evaluate the effect of weight change by the weight control program, anthropometric measurements, biochemicl parameter, and food behavior are measured. The mean body mass index(BMI) was 30.1$\pm$3.8(25.0-43.6) and it was in the upper 5 percentile of the mean BMI of Korean women. The percent of body fat was significantly reduced from 29.1$\pm$2.4 to 26.4$\pm$2.3, showing that the weight control program induced not only a change in weight but also a change in body composition. The body circumference such as waist and hip circumference and skinfold thickness measurements of biceps, triceps, subscapular and surprailiac were reduced significantly, but the mean waist-to-hip ratio didn't change. Singnificantly improved food behavior score measured by the questionnaire indicated that the weight-contorl program induced the change of the food behavior, as well. Weight loss also induced biochemical parameters of the subject, thus total cholesterol, LDL-Cholesterol, and triglycerol which were in the high range of the normal values were reduced to 20.2%(p<0.01), 22.2%(p<0.01), 25.8%(p<0.01), repectively. HDL-cholesterol didn't change significantly, but the ratio of HDL to total cholesterol increased(p<0.01).
We investigated the reproductive cycle with ovarian development of Chlamys farreri by histological observations, and seasonal changes in biochemical components of the adductor muscle, digestive diverticula and ovary were studied by biochemical analysis. The reproductive cycle of this species can be classified into five successive stages: early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (June to August) and spent/inactive stage (August to January). According to ANOVA test, there were significant differences (p < 0.05) in total protein, total lipid and glycogen contents among months for all of the adductor muscle, digestive diverticula and ovary. Total protein contents in ovary and digestive diverticula showed significant changes (ANOVA, p < 0.05) during the study period, while that in the adductor muscle did not. Total protein content was highest in the adductor muscle, followed by ovary, and lowest in digestive diverticula. There was no correlation in total protein content between the adductor muscle and digestive diverticula (p = 0.220). But strong positive correlation was found between adductor muscle and ovary (r = 0.450, p = 0.013). ANOVA showed that there were significant differences in total lipid and glycogen contents among months for all of the adductor muscle, ovary, and digestive diverticula (p < 0.05). The monthly changes in total lipid content were highly variable in ovary and digestive gland. High contents of total lipid were found during April and May-June in ovary, while March and June-July in digestive diverticula. There was a strong negative correlation in total lipid content between ovary and digestive diverticula (r = -0.397, p = 0.030). Unlike total protein or total lipid, glycogen content in the adductor muscle was most dynamic. It showed more than 36-fold changes in the adductor muscle (at most 3-fold change in ovary) during the study period. Glycogen content was higher during May-July in the adductor muscle, while it was higher in March and August in digestive diverticula. There was a strong negative correlation in glycogen content between the adductor muscle and digestive diverticula (r = -0.584, p = 0.001).
We investigated the reproductive cycle with gonadal development of the female Cyclina sinensis by histological observations and seasonal changes in biochemical components of the adductor muscle and visceral mass tissues were studied by biochemical analysis, from January to December, 2001. The reproductive cycle of this species can be classified into five successive stages: early active stage (February to April), late active stage (March to June), ripe stage (May to August), partially spawned stage (July to October) and spent/inactive stage (September to February). Total protein contents in the adductor muscle tissues reached the maximum in February (early active stage) and appeared the minimum in June (ripe stage), while their contents in the visceral mass tissues reached the maximum in the late active and ripe stages (June) and gradually decreased from July (partially spawned stage) to November (spent/inactive stage). Changes in total protein contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.499, p = 0.099). Total lipid contents in the adductor muscle tissues reached the maximum in January (the inactive stages) and their contents gradually decreased from February. Their contents in the visceral mass tissues, however, reached the maximum in June (late active and ripe stage) and gradually decreased from July (the partially spawned stage). On the whole, total lipid contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.631, p < 0.05). Therefore, These results indicate that the nutrient contents of the adductor muscle and visceral muscle tissues change in response to gonadal energy needs. Glycogen contents in the adductor muscle tissue reached the maximum in March (early and late active stages) and decreased from July to September (partially spawned stage). while their contents in the visceral mass tissues reached the maximum in June (late active and ripe stages) and gradually decreased from July (partially spawned stage). Thereafter, their levels gradually increased in November (spent/inactive stage). On the whole, changes in glycogen contents appeared negative correlationship between the adductor muscle and visceral mass tissues. However, they showed no significant different (r = -0.307, p = 0.331).
The response of vegetation under the crop stress condition was evaluated using structural, biochemical, and physiological vegetation indices based on unmanned aerial vehicle (UAV) images and field-spectrometer data. A high concentration of herbicide was sprayed at the different growth stages of garlic to process crop stress, the above ground dry matter of garlic at experimental area (EA) decreased about 46.2~84.5% compared to that at control area. The structural vegetation indices clearly responded to these crop damages. Spectral reflectance at near-infrared wavelength consistently decreased at EA. Most biochemical vegetation indices reflected the crop stress conditions, but the meaning of physiological vegetation indices is not clear due to the effect of vinyl mulching. The difference of the decreasing ratio of vegetation indices after the herbicide spray was 2.3% averagely in the case of structural vegetation indices and 1.3~4.1% in the case of normalization-based vegetation indices. These results meant that appropriate vegetation indices should be utilized depending on the types of crop stress and the cultivation environment and the normalization-based vegetation indices measured from the different spatial scale has the minimized difference.
Prevalence of an obese population has been increasing in Korea. Obesity is considered a major risk factor for chronic degenerative diseases. Specifically, prevalence of obesity is prominent for adult woman in Korea. In many weight control programs, weight change did not often show any beneficial effects for health. These facts discourage people in the program. Thus in this study, the anthropometry, blood pressure, serum biochemical indices and dietary habits were compared by percent body fat change for adult women to show the beneficial effects of the weight control program. Study subjects were 134. Measurements were done before and after the weight control program. Percent Body Fat (PBF) was measured by bioelectrical impedance analysis. Using PBF changes, subjects were grouped as I (more than 1% increase), M (${\pm}1%$ change), and D (more than 1% decrease). Data were analyzed using SPSS 12.0 program. Among the 134 participants, 13 increased their weight and 100 decreased. For PBF, 19 increased and 59 decreased. Statistical significant differences were shown for anthropometric assessments before and after for all weight, fat mass, percent body fat, waist-hip ratio and body mass index. I had increases, and D shows decreases. But the difference of D is large than M. Systolic and diastolic blood pressures decreased in all groups (p < 0.05). Fasting blood glucose decreased in all groups but were statistically significant only in D. Also triglyceride decreased in D (p < 0.05). Thus health conditions showed desirable changes in I < M < D in order. Dietary habit changes were desirable with only D. Weight, BMI and other indicators for obesity is not the real indicator for PBF. Recently it is easy to measure PBF. Thus, for weight control programs and to show benefits of the program, PBF is a good indicator for adult women in Korea.

The effect of topical application with 200,400 and 600 $\mu$g/ml 2,4-Dichlorophenoxyacetic Acid (2,4-D) and Naphthoxyacetic Acid (NOA) to the fifth stadium larvae of the silkworm, B. mori on fat body glycogen, protein, total lipids, phospholipids, neutral lipids and haemolymph trehalose and protein has been studied. The fat body glycogen significantly increased in all the groups treated with 2,4-D whereas there is no significantly change in fat body glycogen in all the groups treated with NDA. However, the haemolymph trehalose was significantly increased in all 274-D and NOA treated groups except in the groups treated with 400 and 600 $\mu$g/ml 2,4-D where the increase was not significant.The fat body protein did not show any significant change in all groups treated with 2,4-D and NOA except in the groups treated with 200 $\mu$g/ml 2,4-D where the fat body protein was significantly increased. The total lipids, phospholipids and neutral lipids of the fat body increased significantly in all the groups treated with 2,4-D and NOA when compared with those of the corresponding parameters of the carrier control.
Liver cirrhosis (LC) is defined as comprising diffuse fibrosis and regenerating nodules of the liver. The biochemical and anatomical dysfunction in LC results from both reduced liver cell number and portal vascular derangement. Although several studies have investigated dysregulated genes in cirrhotic nodules, little is known about the genes implicated in the pathophysiologic change of LC or about their relationship with the degree of decompensation. Here, we applied cDNA microarray analysis using 38 HBsAg-positive LC specimens to identify the genes dysregulated in HBV-associated LC and to evaluate their relation to disease severity. Among 1063 known cancer- and apoptosis-related genes, we identified 104 genes that were significantly up- (44) or down- (60) regulated in LC. Interestingly, this subset of 104 genes was characteristically correlated with the degree of decompensation, called the Pugh-Child classification (20 Pugh-Child A, 10 Pugh-Child B, and 8 Pugh-Child C). Patient samples from Pugh-Child C exhibited a distinct pattern of gene expression relative to those of Pugh-Child A and B. Especially in Pugh-Child C, genes encoding hepatic proteins and metabolizing enzymes were significantly down-regulated, while genes encoding various molecules related to cell replication were up-regulated. Our results suggest that subsets of genes in liver cells correspond to the pathophysiologic change of LC according to disease severity and possibly to hepatocarcinogenesis.
Hepatoprotective effects of the water extract of Protaetia brevitarsis larva (PB) was investigated in carbon tetrachloride ($CCI_{4}$) treated male Sprague-Dawley rats. PB administration protected rats against ALT, AST and LDH elevations induced by $CCI_{4}$, as well as the severity of liver damage. PB recovered the decrease in serum level of high-density lipoprotein-cholesterol and the increase in serum level of low-density lipoprotein-cholesterol induced by $CCI_{4}$. In histopathological observation, massive fatty change and necrosis in the centrilobular area, degenerative change including pyknosis of nucleus and swelling of parenchymal cell induced by $CCI_{4}$ were clearly protected by PB. These histopathological findings paralleled with the serum biochemical results. The present results demonstrated that the water extract of PB may have the hepatoprotective effect against $CCI_{4}$-induced liver damage in vivo.

Diazinon, an organophosphate pesticide, is relatively highly toxic to fish and causes vertebral malformation and behavioral change of fish at relatively low concentrations. To elucidate biochemical mechanism of the behavioral change of Oryzias latipes (killifish) caused by diazinon, the effect of the insecticide on acetylcholine esterase activities and the levels of some neurotransmitters were evaluated. Acetylcholine esterase activities in both head and body were significantly lowered at the concentration of 10 ppb of diazinon and acetylcholine contents in head tended to be upregulated with increasing concentration of diazinon. Exposure of killifish to 5000 ppb diazinon resulted in gradual decrease in acetylcholine content in body part with exposure time. Norepinephrine and serotonin concentrations in killifish head and body were highest at 1000 ppb of diazinon while neurotransmitter were relatively low in fish unexposed or exposed to lower dose of the pesticide, suggesting that increased norepinephrine and serotonin can partially account for diazinon-induced behavioral abnormality.
Antheraea yamamai vitellin was purified from matured eggs by polyacryamide gel electrophoresis, also stage dependent appearance, immunological comparison and relative content of the protein were investigated. 1. Vitellogenin, the precursor of vitellin, was first detected in the larval hemolymph at the late spinning stage by polyacrylamide gel electrophoresis and immunoelectrophoresis. 2. The electrophoretic mobility of the vitellin was identical with that of Bombyx mori and of Bombyx mandarina. However, the specific antiserum against A. uamamai vitellin did not react with either that of Bombyx mori or Bombyx mandarina in immumo-diffusion test. 3. Relative content of A. yamamai vitellin to the total soluble egg protein was 46.0 percent and did not change till eight days after oviposition. But the content started to decline from ten days after oviposition and was negligible in the five or serventeen month old eggs.
