Purpose: This study sought to identify whether fascial therapy using myofascial release (MFR) and Fascial Distortion Model (FDM) techniques affected not only the area where treatment was being given but also remote areas connected to the treatment area by fascial continuity through comparison of the pain pressure threshold (PPT). Methods: The subjects were 16 healthy normal adults in their 20s and 30s who were divided into the MFR and FDM groups before the experiment. The PPT was measured at 4 different points on the body of the subjects. C7, T7, L5, and gastrocnemius along the superficial back line (SBL) before and after the intervention. Results: Only the FDM group subjects showed a significant increase in the PPT at T7 after the intervention. (p<0.05). In addition, the FDM group demonstrated significantly increased PPT at L5 compared to the MFR group. However, neither the FDM nor the MFR group showed a meaningful change in the PPT at the remote area in the lower leg. Conclusion: These findings showed that FDM can affect PPT more and has a positive effect on the pain threshold compared to MFR. However, neither FDM nor MFR showed any effect on the PPT in a remote area.

Slow-release fertilizers (SRF) have been used to reduce nutrient loss through increasing fertilizer efficiency and to save labor. Several SRFs were developed for rice plant in Korea, but there is few for horticultural crop plants. Two slow-release complex fertilizers, 100T and 150T, which made for controlling nitrogen release time up to 100 and 150 days, respectively, were selected for the incubation test cto evaluate nitrogen (N) release rate in soil. The N of urea selected as the control was completely released within a week after application. Sixty three and 53% of total N were released from 110T and 150T of slow release fertilizers within 8th weeks after application, respectively. For pepper cultivation CF110 and CF150, new slow-release complex fertilizer, were made of mixing 40% of conventional fertilizer and 60% of 110T and 150T, respectively, based on the amount of recommended fertilizer for pepper cultivation $(N-P_2O_5-K_2O=190-112-149\;kg\;ha^{-1})$, and were totally applied before pepper transplanting in the field as the basal fertilizer. Inorganic N $(NH_4^+-N+NO_3^--N)$ concentration in soil was higher in the CF110 treatment than in the control (NPK) at all period of pepper cultivation. In the CF150 treatment concentration of inorganic N in soil was low compared to control up to 8th weeks after transplanting. However, there was no difference in plant height and nutrient content of pepper leave between CF110 treatment and the control. In comparison, plant height was significantly lower in CF150 than the control and CF110 treatments. Around 4% of fresh pepper yield was increased in CF110 compared to the control, but it was decreased to about 2% by CF150 treatment. Conclusively, CF110 form could be recommended as a slow release fertilizer for pepper cultivation.

Diversification and individualization are pursued to fulfill the increasing human desire for beauty. There are many methods to change human appearances; of these, a permanent wave is often applied to improve beauty. A permanent wave uses physical and chemical methods to break and reform the bonds of natural hair. Thus, research into the optimized conditions for permanent waves is necessary to minimize hair damage and improve the efficiency of the treatment. The object of this study is to examine the effect of varying the alkalinity (8%, 12%, and 16%) of the permanent wave treatment on the wave efficiency, degree of hair damage via tensile strength, and degree of hair protein release. The results indicate that the treatment with the highest alkalinity (16%) is more effective than that with 8% alkalinity; however, the degree of hair damage when treated with the 16% alkalinity wave is higher than with the 8% alkalinity wave. Additionally, hair proteins increasingly dissolve with increasing alkalinity of the permanent wave.

Lipofibromatous hamartoma (LFH) is a rare tumor of the peripheral nerves, which usually involves the median nerve. The authors reported on two rare cases of carpal tunnel syndrome due to LFH of the median nerve. A 49-year-old female patient complained of the mass and symptoms consistent with LFH. Magnetic resonance imaging (MRI) showed typical LFH findings. The symptoms were successfully ameliorated with carpal tunnel release and external neurolysis. A 37-year-old female patient complained of weakening thumb abduction and the mass where the MRI showed atypical findings. Opponensplasty and debulking operations were performed after which thumb abduction was improved; however, neurological sequelae remained. LFH of the median nerve is managed on a case-by-case basis as treatment guidelines are not very clearly defined yet. However, the less invasive treatment such as carpal tunnel release and external neurolysis than more aggressive surgical treatment should be recommended as a treatment option.

Objectives : The water extract of Hwangnyeonhaedok-tang (HHT), composed of the Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus has been traditionally used to treat fever, inflammation, gastritis and hypertension in east asia. However, little is known about the ameliorative effects of HHT on atopic dermatitis. Therefore, the purpose of this study was to investigate the therapeutic effect of HHT on atopic dermatitis Methods : We investigated the inhibitory effects of HHT on the production of proinflammatory cytokines in rat peritoneal mast cells (RPMCs), on the scratching behavior in ICR mice, and on atopic dermatitis symptoms in 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis-like model hairless mice. Results : Levels of TNF-${\alpha}$ and IL-$1{\beta}$ increased by PMA plus A23187 co-treatment were significantly inhibited by HHT in a dose-dependent manner. HHT also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. The oral administration of HHT reduced the scratching behavior induced by compound 48/80 and histamine in ICR mice. Furthermore, the intradermal treatment of HHT reduced the ear edema, skin lesions, and atopic molecular marker (IgE and IL-4) in DNFB-induced atopic dermatitis model mice. Conclusions : These results suggest that HHT may be used as a potential treatment for AD as a prescription for treatment of atopic dermatitis.

The effectiveness of fly ash-, quicklime-, and quicklime-fly ash-based stabilization/solidification(S/S) in chromium(Cr) contaminated soils was investigated using modified semi-dynamic leaching tests. Artificial soil samples composed of kaolinite or montmorillonite contaminated with chromium nitrate(4000 mg $Cr^{3+}\;kg^{-1}$ of solid) were prepared and then subjected to S/S treatment using quicklime, fly ash, or quick lime-fly ash. The effectiveness of the treatment was evaluated by assessing the cumulative fraction of leached $Cr^{3+}$ as well as, by computing the effective diffusivity ($D_e$) and the leachability index (LX) of the treated samples. The reduction in $Cr^{3+}$ release for the untreated samples was more pronounced in the presence of montmorillonite, which was attributed to sorption. Treatment with quicklime, fly ash, or quick lime-fly ash was significantly effective in reducing $Cr^{3+}$ release most probably due to the formation of pozzolanic reaction products and $Cr(OH)_3$ precipitation. The most effective treatment was observed in montmorillonite-sand soil samples treated with quicklime-fly ash (99.8% removal). The mean $D_e$ decreased significantly and the mean LX was greater than 9 for all treated samples, indicating that the treated soils were acceptable for "controlled utilization". The mechanism controlling $Cr^{3+}$ leaching from all treated samples during the first 5 days appeared to be diffusion.

The trophic factor Neuregulin-1 (NRG-1) plays a critical role in the development of the peripheral nervous system and the repair of nerve injuries. The regulation of neutrophil apoptosis by cytokine secretion from structural cells is an important process in inflammatory diseases, including asthma. This study aimed to investigate the relationship between NRG-1 and the alteration of neutrophil apoptosis by the regulation of cytokine release in the human lung epithelial BEAS-2B cells. Tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) induce the increase in the release of interleukin (IL)-6, IL-8, and monocyte chemoattractant protein-1 (MCP-1). NRG-1 alone had no effect on the secretion of IL-6, IL-8, and MCP-1. However, co-treatment of TNF-α and IFN-γ with NRG-1 inhibited the secretion of IL-6, IL-8, and MCP-1 that had been increased by TNF-α and IFN-γ. Treatment with NRG-1 did not have a direct effect on neutrophil apoptosis. Co-treatment of TNF-α and IFN-γ with NRG-1 was not effective on suppression of neutrophil apoptosis due to TNF-α and IFN-γ. The supernatant of BEAS-2B cells after co-treatment of TNF-α and IFN-γ with NRG-1 suppressed the inhibition of neutrophil apoptosis that had been caused due to the supernatant treated with TNF-α and IFN-γ. Taken together, NRG-1 has an anti-inflammatory effect in an inflammatory milieu by the regulation of cytokine secretion and neutrophil apoptosis.

As it has been reported that the depolarization-induced norepinephrine (NE) release is modulated by activation of presynaptic $A_1$-adenosine heteroreceptor and various lines of evidence indicate that $A_2$-adenosine receptor also presents in hippocampus, and that the adenosine effect is magnesium dependent, the present study was undertaken to delineate the role of adenosine receptors in the modulation of hippocampal NE release. Slices from the rat hippocampus were equilibrated with $[^3H]-NE$ and the release of the labelled product, $[^3H]-NE$, was evoked by electrical stimulation (3 Hz, 5 V $cm^{-1}$, 2 ms, rectangular pulses), and the influence of various agents on the evoked tritium outflow was investigated. $N^6-cyclo-pentyladenosine$ (CPA), in concentrations ranging from 0.1 to 10 ${\mu}M$, decreased the $[^3H]-NE$ release in a dose-dependent manner without changing the basal rate of release, and these effects were significantly inhibited by 8-cyclopentyl-1,3-dipropylxanthine (DPCPX, 2 ${\mu}M$) treatment. When the magnesium concentration was reduced to 0.4 mM or completely removed, the evoked NE release increased along with decreased basal rate of release. In contrast, increasing the magnesium concentrations to 2.4 and 4 mM, decreased the evoked NE release. The CPA effects on evoked NE release were reducedby magnesium removal, but potentiated by 2.4 mM magnesium in the medium. 5-(N-cyclopropyl)-carboxamodiadenosine (CPCA, 1 & 10 ${\mu}M$), an $A_2$-agonist, decreased the evoked tritium outflow, and this effect was also abolished by DPCPX pretreatment. CGS, a powerful $A_2$-agonist, did not affect the evoked NE release. However, the effects of CPCA and CGS on evoked NE release were significantly increased by pretreatment of DPCPX in the magnesium-free medium. These results indicate that inhibitory effect of $A_1$-adenosine receptor on NE release is magnesium-dependent, and $A_2$-receptor may be present in the rat hippocampus.

This study was performed to investigate the effects of recombinant BST formulation treatment on the milk yield, milk components, mastitis, and general cow health condition when the formulations of retinyl palmitate, cholecalciferol and rBST were administered after the peak period of milk production. The milk yields of treatment groups (Group I, II, III and IV) were increased from 21.5% to 29.0% than that of control group. There was significant difference in milk production between treatment group II, IV and control group (P<0.05). However, there was no significant difference in milk production between treatment group I, III and control group (P<0.05). And the addition of retinyl palmitate and cholecalciferol into rBST formulation did not increase the milk yield. The milk of treatment groups with sustained-release rBST did not show significant difference in milk components (milk fat, protein, lactose, and solid not fat). However, there were minor changes, primarily in fat content of milk, during the first few weeks of rBST administration. There was no incidence of clinical mastitis between rBST treatment groups and control group. Addition of high and medium concentration of retinyl palmitate and cholecalciferol into sustained-release rBST formulation was efficient in reduction of somatic cell count in milk. There was great energy deficit in all treatment groups compared with control group during the early study period. Thus, the body condition score of all treatment groups showed lower value than control group. No evidences of metabolic health problems, such as ketosis, milk fever, and downer cow were observed. Incidence of general lameness did not appear on all treatment groups during 140 days of this study.
