  • Multiplication and spore production of three microsporidia viz., Nosema bombycis, Nosema sp. 1 and Nosema sp. 2 in fifth instar larval tissues of silkworm, Bombyx mori L. in two seasons with distinct temperature regimes were studied. Nosema sp. 2 produced significantly (P < 0.01) higher number of spores in various tissues. Among the tissues, spore production was highest in silk gland, followed by fat body and gut. Spore production was significantly (P < 0.01) higher in season-II (Average temperature $29.4{\pm}1.1^{\circ}C$). Maximum spore production was observed 25 days post inoculation (p. i.) in season-I (Average temperature $18.9{\pm}1.1^{\circ}C$), whereas in season-II, it was 14 days p. i. In season-I, spore production was low up to 21 days p. i., then increased sharply. In season-II, there was a steady increase in spore production. The results indicate that the microsporidian multiplication is tissue specific and extremely sensitive to temperature at which the host is reared. It also reveals that, silk gland, fat body and gut are the most appropriate tissues for microscopic identification of microsporidia in the larval stage.

  • Saponin, essential oil and fat oil fractions were fractionated from Panax Ginseng and their potentiating or inhibiting actions during the combined use of several central nervous system stimulants or depressants were observed to elucidate the possible role of Ginseng fractions on the central nervous system. Saponin, essential oil and fat oil fractions shortened nembutal sleeping time at low dosage (10 mg/kg) but contrarily they produced potentiation of nembutal hypnosis at high dosage (50mg/kg). In the toxicity study of amphetamine, saponin and essential oil fractions reduced the toxicity in aggregated mice at high dosage (100 mg/kg) but such decreased lethality was not observed in isolated mice. Ginseng fractions, especially high dose of saponin fraction (100mg/kg) prolonged the survival time after injection of convulsive dose of metrazol or cocaine and saponin fraction also prolonged the onset of cocaine convulsion at high dosage (100 mg/kg).

  • The experiment was conducted to investigate the feasibility of using vegetable oil and non-fat dry milk (powdered milk) with skim milk for the preparation of dahi. In this experiment, six different types of dahi were prepared from whole milk, skim milk and admixture of non-fat dry milk with different levels of vegetable oil. The prepared dahi samples were subjected to physical, chemical and microbiological analysis to evaluate their quality. It was observed that the addition of non-fat dry milk and vegetable oil with skim milk improve the physical qualities (smell and taste, body and consistency, color and texture) of prepared dahi samples. Addition of non-fat dry milk and vegetable oil also improve the total solids, fat and protein content of dahi samples. It is concluded that the addition of vegetable oil at a rate of 4 to 6% together with 5% non-fat dry milk gave the best result.

  • To investigate the effects of exercise-training on serum lipids, fat distribution and several parameters of body fatness(percent body fat, skinfolds thickness, body circumference) were assessed in 24 healthy male subjects submitted to an 8-wk high intensive exercise-training. Blood sample was taken twice, per and post exercise-training, Exercise-training took place 5 days a week and daily energy intake and expenditure were observed. The results obtained are summarized as follows: 1) Through exercise-training body weight (changes : 1.1$\pm$1.1kg ; p=0.000) and percent body fat (changes : 2.4$\pm$1.3% ; p=0.000) decreased significantly . 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$1.7mm and 0.2$\pm$1.9mm. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) Total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly changed by exercise-training while only triglyceride decreased (changes : 20.7$\pm$44.8mg/dl ; p<0.05). Changes in body weight were grately related to changes in total cholesterol. Changes in deep abdominal adipose tissue were related to changes in triglyceride.

  • Objectives Previously, we demonstrated that a 5% ethanol extract of unripe Rubus coreanus (5-uRCK) and ellagic acid has hypocholesterolemic and antiobesity activity in high-fat diet-fed animals. Therefore, we conducted a clinical study on the anti-obesity effect of 5-uRCK in 140 Korean adults (aged 19-70 years, body mass index (BMI) ≥25 kg/m2). Methods The participants were randomly assigned to two groups and were administered the placebo (n=70) or 5-uRCK extract (800 mg, n=70) daily for 12 weeks. The subjects were instructed to maintain their usual dietary intake and normal physical activity. Anthropometrics, body composition (dual-energy X-ray absorptiometry), and blood parameters were compared between the two groups. Results Average body weight and BMI did not show any significant changes; however, changes in upper body fat mass between the two groups was significantly different, as determined using analysis of covariance adjusted for baseline of percent body fat and drinking units. Moreover, Although not significant, the trunk fat mass and percent trunk fat tended to decrease after 5-uRCK supplementation. There was no significant difference in other laboratory biomarkers between the two groups. All safety parameters were within normal ranges in the both group. Conclusions In the present study, 5-uRCK significantly reduced upper body fat in obese subjects after 12 weeks, which indicates that it may help improve android-type obesity. Furthermore, the supplement is safe and well tolerated.

  • Tropical tasar silkworm Antheraea mylitta Drury experiences extreme temperature stress conditions during its life cycle particularly during diapauses and first crop. The present study witnessed the impact of high temperature on some biochemical profiles and egg production (fecundity) of semi-domesticated Daba and Shorea robusta (Sal) based wild ecorace Laria during seed cocoon (pupa) preservation. Cocoons of Daba and Laria were treated with high temperature at $40^{\circ}C$ for 10 days in a BOD incubator. The protein profile and carbohydrate content in the hemolymph and fat body and total haemocyte count (THC) in the hemolymph of pupa were investigated. Further, the fecundity and fertility of egg was assessed. Significant increase in the protein concentration was observed in the hemolymph with reduction in the fat body (p<0.05). The difference in protein concentration was highly significant between the semidomesticated Daba and wild ecorace Laria (p<0.05). High pupal mortality (20%) and reduced fecundity (10-15%) in Daba was noticed compared to wild Laria. Also an increased THC (>28000) was recorded in Laria. The study infers the potentials of wild ecoraces in sustaining the extreme temperature conditions and need of adopting suitable package of practices for the preservation of diapause seed cocoons during extreme summer conditions. There is possibility to introgression thermal stress resistant traits in the semi-domesticated races of tasar silkworm by resorting to conventional breeding plans with wild races and keeping the thermal stress induced response as markers.

  • This study was conducted to investigate the physical characteristics and risk factors for hyperchol-esterolemia (HC) in Korean. 344 adult men who took the annual health check-ups at D or J hospitals were participated in this cross-sectional study. The subjects were grouped by plasma total cholesterol level in to three groups: normal cholesterolemic (n=139) borderline hypercholesterolemic(n=93) and hypercholesterolemic (n=112) groups. The data of height weight and plasma cholesterol level were col-lected from medical records. Body circumferences(midarm, waist, hip, and thight) skinfold thicknesses (biceps, triceps, subcostal, abdomen, and suprailic), and body composition (fat mass and fat free mass) were measured. Body mass index (BMI) height/weight ratio (HWR) waist/hip circumference ratio (WHR) waist/ thigh circumference ratio (WTR) central skinfold thickenss (CSF) and peripheral skin-fold thickness were calculated. The subjects with HC had significantly higher weight BMI waist cir-cumference skinfold thickness and body fat mass than those of the normal subjects. The relative and attributable risks on HC were 1.61 and 0.17 for obesity (BMI$\geq$25) 1,30 and 0.11 for upper body obesity (WTR$\geq$1.30) and 1.54 and 0.18 for central body obesity (CSF$\geq$95.7). Plasma total cholesterol level was positively correlated with several antropometric parameters: BMI (p<0.001) weight(p<0.001) waist circumference(p<0.001) and skinfold thickness of abdomen (p<0.001) spraillic (p<0.01) triceps(p<0.01) subcostal (p<0.01) and biceps (p<0.05) In conclusion the major influencing factors to plasma cholesterol level was BMI. Among the each physical parameters the circumference of waist the skinfol-d thickness of abdomen and the percentage of body fat were closely related to plasma cholesterol level. The important risk factor for hypercholesterolemia was obesity specially upper body obesity and central body obesity.

  • Truncal obesity associated with insulin resistance and metabolic syndrome increase the likelihood of hypertension, various cardiovascular diseases, hyperlipidemia and coronary heart diseases. International Diabetes Federation (IDF) experts recognized that it is necessary to develop the simple diagnostic tool which is applicable to diagnose truncal obesity worldwide, and proposed the method using a waist circumference but there is a limit to estimate subcutaneous fat distribution. However, waist line is also influenced by total fat capacity less than the intra abdominal fat. The more having severe obesity, the more correlation coefficient between waist line and intra abdominal fat is low. Therefore, this thesis defines a new abdominal impedance measurement position and impedance-index to analysis central obesity. This proposes the new model to estimate abdominal obesity using the abdominal impedance-index and CT images acquired fro 160 Korean subjects. The proposed model shows that the abdominal fat distribution has a higher correlation than waist line. (Adj R2=0.809, 0.667 and 0.687 with abdominal fat area, visceral fat area and subcutaneous fat area respectively).

  • Objectives: Obesity is becoming more popular disease worldwide. Because of the side effects of conventional obesity treatment modality, herbal medicine treatment is becoming more preferred. Gambihwan which including Ephedra sinica Staph is widely used in traditional Korean Medicine practice for obesity treatment. Garcinia cambogia is a kind of health functional food that has body fat reducing effect. Nowadays, ephedra and Garcinia cambogia are often used simultaneously in clinical practice of Korean Medicine. However, the effectiveness and safety of combination therapy in obesity treatment is not well established. Methods: We conducted retrospective observational study to explore effectiveness and safety of combination therapy. We evaluated effect of combined treatment of Gambihwan and Garcinia cambogia on body weight, body mass index, body fat mass, and waist hip ratio reduction. We also assessed safety via liver function test and adverse event. Results: Finally, 23 patients were included. In paired t-test, body weight significantly decreased from 64.50±14.50 kg to 62.94±13.85 kg (P<0.001) and body mass index were also significantly decreased from 24.43±3.79 kg/㎡ to 23.83±3.59 kg/㎡ (P<0.001). Body fat mass was also reduced. Aspartate transaminase and alanine aminotransferase were not significantly increased. There were no drug-induced liver injury and no severe adverse event. Conclusions: In our retrospective review, we found combination therapy of Gambihwan and Garcinia cambogia reduce body weight, body mass index and body fat mass. There were no severe adverse event and drug induced liver injury which indicated safety of combination therapy in obesity treatment.

  • Anti-obesity effects of ginseng and herbal plant mixtures were investigated to develop natural materials for anti-obesity. After inducing obesity with high fat diet for 8 weeks in male SD rats, ginseng and herbal plant mixtures DM1 (ginseng, puer tea, opuntia) and DM2 (ginseng, puer tea) were administrated orally to rats for another 8 weeks. During administration, food efficacy ratio and body weight of rat were measured twice weekly. After administration, body weight, body fat contents, and serum lipid level were estimated for anti-obesity effect and hematological analysis blood level of ALP and ASP was checked for safety. Body weight in rats fed high fat diet was significantly increased. Body weight in obese rats induced by high fat diet was significantly decreased by DM1 and DM2 feedings. The amount of body fat (epididymal, perirenal and visceral fat, brown adipose tissue) was significantly reduced by DM1 and DM2 treatments. The amount of TG, the concentration of leptin in blood plasma, and the concentration of insulin in blood plasma were significantly diminished by DM1 and DM2. Lipid accumulation on liver was reduced in DM2. There were no side effects among all groups according to blood analysis, hematological findings, and body weight. The findings of this study suggest that DM1 and DM2 may be effective materials for anti-obesity through reducing plasma triglyceride and body fats, and also decreasing body weight without side effects.
