The possiblity of sepiae os as a calcium supplement in food was studied. Elementary contents of sepiae os were as follows; Ca 53.254%, O 26.781%, Na 14.905%, Cl 4.37%, Sr 0.507%, P 0.068% and Si 0.051%, respectively. Most of calcium in sepiae os was present as a form of CaCO3. Sruface area of sepiae os was found as 386 m2/g, and scanning electron micrograph showed sepiae os has multilayer struture. Buffering capacity of sepiae os that of CaCO3. With above results, sepiae os can be used as a calcium supplement in food with good chacterateristics.

This study was performed to evaluate antiulcer effects of traditional folk medicines such as heat-treated acumen, halloysitum rubrum and os sepiae against stomach ulcer induced by acetic acid in Sprague-Dawley rats. Various pharmacological parameters were utilized to compare the antiulcer effects of aforementioned drugs based on the size of ulcer lesion, pepsin activity, free and total acidity, gastric secretory volume, and 5-HT (hydxoytrytamine) content. All folk medicines and ranitidine as control drus were shown to decrease ulcer lesion size after 5-day treatments, with the order of halloysitum rubrum, os sepiae, heat-treated acumen and ranitidine. All treated drugs except os sepiae inhibited the gastric volume as compared with that in the control group. Ranitidine most significantly inhibited the gastric volume. All the experimented drugs in this study lowered the gastric acidity. Halloysitum rubrum decreased it most remarkably, followed by ranitidine, os sepiae and heat-treated alumen after 5-day treatments. All used drugs alleviated the pepsin activity as compared with the control group, os sepiae being the highest then halloysitum rubrum, heat-treated alumen and ranitidine in turn. Heat-treated alumen and halloysitum rubrum showed mucin production to the great extent, and ranitidine had slight increasing effect thereon. At the end of observation period, all drugs except ranitidine increased 5-HT contents as compared to the normal group. From the above results, we could confirm the folk medicines such as heat-treated alumen, halloysitum rubrum and os sepiae have not only remarkable antiulcer effects but also preventing effects for the stomach ulcer recurrence, which suggest the experimented folk medicines could be developed as new antiulcer agents.

Objectives: This aim of this study is to compare the reflux esophagitis improvement effects of Sepiae Os, Arcae Concha, Ostreae Concha, and Proton Pump Inhibitor(esomeprazole) through rat experiments. Methods: NO production inhibitory effect was measured by NO production amount and iNOS mRNA expression level in cell lines. iNOS, $TNF-{\alpha}$ and $p-I{\kappa}B$, and serotonin were compared using immunohistochemistry at the rat reflux esophagitis. Reflux esophagitis connection external form, lower esophageal sphincter, and gap were observed and an esophageal inflammatory indicator, IL-6 activity was also evaluated by immunohistochemistry. Results: NO production and iNOS mRNA expression was showed concentration dependent decrease in cell lines treated with Sepiae OS, Arcae Concha, and Ostreae Concha at the experiments of cell lines. In the suppression of iNOS and $p-I{\kappa}B$ at the rat reflux esophagitis, Sepiae Os treat group(SOT) and Ostreae Concha treat group(OCT) were more effective. In the increase of serotonin at the rat reflux esophagitis, ACT, MT and OCT were more effective. Damage of lower esophageal sphincter, and gap between esophageal keratin and mucosa were observed less at the SOT, ACT, OCT. In the suppression of IL-6 at the rat reflux esophagitis, SOT and OCT were more effective than GE and, SOT was more effective than MT significantly. Conclusions: The anti-inflammatory effect was the best in the SOT and lower esophageal sphincter muscle contraction was the best in the ACT at the rat reflux esophagitis. Sepiae OS was more effective than esomeprazole in the suppression of iNOS, $TNF-{\alpha}$, and IL-6.

This study was carried out investigate the effect of sepiae as on the kimchi ferentation. Quality indices were pH, titratable acidity, reducing sugar content, microbial counts, and redness kimchi juice. Sepiae as retarded the decreasing rate of pH and the increasing rate of titratable acidity in kimchi during fermentation at 1$0^{\circ}C$, and the effect was more conspicouous at 1.5% than at 0.5%. Kimchi added with 1.5% sepiae as maintained a similar pH and titratable acidity after 5 days. Microbial counts of total and lactic bacteria were higher in sepiae os added kimchi than control control. Regardless of the of sepoae os, the redness of kimchi juice was gradually increased during storage.
