Ab initio studies of simple model systems for the carboxypeptidase A active site indicate that penta-and hexa-coordinate Zn(II) complexes have comparable structural stabilities. These facile coordination structures can be responsible for the catalytic role. Although the hexa-coordinate Zn(II) complex is more stable in enthalpy than the penta-coordinate Zn(II) complex, the entropy effect makes the latter as stable as or slightly more stable in free energy than the former.

The purpose of this study was to investigate the anti-cancer effects of Carthami Flos in some kinds of human gastric cancer cells. We used two kinds of human gastric cancer cell lines, such as AGS cells and MKN45 cells. We examined cell death by MTT assay and observed the morphological changes with Carthami Flos. Also, we showed that the combination of sub-optimal doses of Carthami Flos and cisplatin noticeably suppresses in AGS cells and doxorubicin in MKN45 cells. Furthermore, we studied the caspase 3 activity to identify the apoptosis. Therefore, our findings provide insight into unraveling the effects of Carthami Flos in human gastric cancer cells and developing therapeutic agents against gastric cancer.

Objective : The purpose of this study was to investigate the anti-cancer effects of Carthami Flos in some kinds of human colorectal adenocarcinoma cells. Method : We used two kinds of human colorectal adenocarcinoma cell lines, such as HT-29 and WiDr cells. We examined cell death by MTT assay and observed the morphological changes with Carthami Flos. Result : We showed that the combination of sub-optimal doses of Carthami Flos and cisplatin noticeably suppresses in HT-29 cells and doxorubicin in WiDr cells. Furthermore, we studied the caspase 3 activity to identify the apoptosis. Conclusion : Our findings provide insight into unraveling the effects of Carthami Flos in human colorectal adenocarcinoma cells and developing therapeutic agents against colorectal cancer.

The purpose of this study is to develop bathing aids as a strategic products to promote the medical tourism in Sancheong Jirisan Oriental medicinal herbs special district using medicinal herbs produced in Sancheong province, and to verify the effect of the bathing aids in vitro. We investigated the cytotoxicity activity, antioxidant activity, antiaging and whitening effects of Sanchung-PNU 1 (SP1) and Sanchung-PNU 2 (SP2) made with traditional medicinal herbs. The cytotoxicity activity was measured by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay. Antioxidant activities were determined by DPPH (1.1-diphenyl-2-picrylhydrazyl) radical scavenging capacity assay. We measured the inhibitory effect against tyrosinase activity to prove the whitening effect, and the inhibitory effect against elastase activity to prove the anti-aging effect. Two proposed prescriptions, SP1 and SP2, showed not significant cytotoxicity but significant (p<0.001) improvement in anti-oxidation, anti-wrinkle, and whitening effects compared to the control group. The result shows that these bathing aids have excellent DPPH radical scavenging effect and significant inhibitory effect against elastase and tyrosinase activity. These findings suggest that these bathing aids have a strong antioxidant, anti-aging, and whitening effect.

Objective : Active treatment for a skin condition has produced a substantial change in the history of allergic contact or wound induced dermatitis. The frequency of opportunistic contacts and allergen-related dermatitis has increased, though new skin treatments have developed. Especially, there has been a interest in the korean herbal bathing. This study was performed to investigate the effects of the korean herbal bathing candidates on skin lesions in mice model. These candidates are Korea's representative herbs on skin lesions. Method : ICR mice were divided into five groups : naive, control, experimental group A and B and C. Control and experimental groups induced skin lesions by DNFB and TMA. Each experimental group was pasted with corresponding korean herbal bathing candidates on skin lesions. Result : Significant improvements in skin wound index, epidermal thickness associated with skin lesions were seen with the korean herbal bathing candidates. Conclusion : These results suggest that the korean herbal bathing candidates could be at least as effective as steroid, anti-histamine for the treatment of skin lesions.
