Zosterin is a pectin from a seagrasses of the family Zosteraceae. Zosterin was given to rats intragastrically once 1h before the emotional stress or injection of indomethacin, or administration of 2, 4-D solution daily for seven days at dose of 100 mg/kg. The data obtained demonstrate that zosterin enhances resistance of the stomach tissue to various ulcerogenic factors (emotional stress, indomethacin, pesticide 2, 4-D). It was shown to possess a gastroprotective effect, which is accompanied by diminution of the number and sizes of destructive regions in the gastric mucosa during the ulcer affection, as well as reduction of ATP and glycogen deficit, decrease of lactate excess, and normalization of the energy balance in the gastric mucosa. According to its antiulcer effect, zosterin may be recommended for application in prevention and treatment of stomach diseases together with the basic therapy.

The effect of ginseng on gastric ulcer and gastric acid secretion was investigated in pylorus-ligated rats. Methods: Sprague-Dawley strain rats were used after 24 hours fast. Pylorus-ligation was performed under light ether anaesthesia, then gastric mucosal damage was evoked in conscious pylorus-ligated rats by the administration of subcutaneous (s.c.) indomethancin (20mg/kg), s.c. histamine (150mg/kg) or by pylorus-ligation (Shay ulcer). Ginseng was given by intragastric (i.g.) or intraperitoneal (i.p.) route simultaneously with the ulcerogens. Rats were killed after 3h (indomethacin) and histamine models) or after 18h (Shay ulcer), when the gastric secretory responses, the number and severity of gastric mucosal lesions and mucosal mucus content deetermined. the effect of i.p. ginseng on basal gastric acid secretion and on gastric acide secretion in indomethacin (20mg/kg, s.c.)-treated rats was also investigated in urethane anesthetized rats. Gastric acid secretion was measured by flushing of the gastric lumen with saline every 15min through an oesophageal cannula. Results: In conscious pylorus-ligated rats, i.g. ginseng(12.5-50mg/$m\ell$; 50-200mg/kg) protected against gastric mucosal lesions evoked by s.c. indomethacin or s.c. histanmine in the d3-h pylorus-lighted rat, withoutmodifying gastric acid secretory responses. Ginseng given i.p. (150 or 200mg/kg) did not reduce the gastric lesions produced by histamine or by ligating the pylorus (Shay ulcer) Ginseng given orally in 50mg/$m\ell$ (200mg/kg) increased gastric mucus secretion in saline- and indomethacin-treated conscious pylorus-ligated rats. In anaesthetized rats ginseng (50 or 200mg/kg) did not modify basal gastric acid secretion or gastric acid secretion in the indomethacin-treated rats. Conclusions: ginseng given orally exerts gastroprotective effects in the rat stomach. Such anti-ulcer effect does not involve changes in gastric acid secretory responses. In addition, ginseng possesses stimulatory effect on gastric mucus secretion, which could be one mechanism by which the compound exerts its antiulcer effect. Our data are in favor for a beneficial effect for topically applied ginseng on the gastric mucosa.

The antiulcer effects of newly synthesized prostaglandin derivatives were investigated in various experimental ulcer models and on gastric secretion in rats. HK-3 and HK-4, PG $E_2$derivatives, prevented the formation of acute gastric ulcer induced by ethanol or aspirin in pylorus-ligated rats. The ulcer formation was moderately inhibited by HK-1 and HK-2, PG $F_{2{\alpha}}$ derivatives, and aggravated by SK-1, SK-2 and SK-3, PG $F_{2{\alpha}}$ derivatives. HK-3 and HK-4 reduced the volume, acid output and pepsin output of gastric juice in pylorus-ligated rats. The gastric perfusion with physiologic saline(pH 6.0) showed relatively constant acid secretion and indomethacin increased the acid secretion. The acid secretion was markedly decreased by PG $E_2$but PG $F_{2{\alpha}}$ caused little change. Prostaglandin derivatives, especially HK-3 arid HK-4, significantly inhibited the acid secretion induced by indomethacin. The results show that, PG $E_2$ derivatives, HK-3 and HK-4, inhibit acid secretion and also have protective effects on gastric ulceration induced by ethanol or aspirin.

This study was undertaken to examine the effects of ultraviolet light (UVL) and rebamipide on the cutaneous blood flow and tissue survival on rabbit skin flap. In a random bipedicle flap, Laser Doppler Flowmetry (LDF) was employed to measure the blood flow of flap (BFF). Wound Margin Strength (WMS) measured by force transducer and Light microscophy were used for evaluation of tissue viability. Single exposure to UVL increased the BFF gradually for more than 15 hours, and decreased the vasoconstrictor effect of intravenous phenylephrine. The UVL-induced increase in BFF regressed after 18 hours of irradiation, and this regression was tended to be enhanced by intradermal injection of L-NAME, a nitric oxide synthase (NOS) inhibitor, but the regression was significantly reversed by acetylcholine, an endothelial constitutive NOS (cNOS) activator and L-arginine, an NO precusor. Rebamipide, a novel antiulcer agent known to scavenge the hydroxyl radical, abruptly reversed the spontaneous regression of the UVL- induced increase in BFF by the same manner as L-arginine. In ischemic skin flap, rebamipide increased the BFF abruptly by the same manner as sodium nitroprusside (SNP), an NO doner, while N-acetylcystein (NAC), a free radical scavenger, gradually increase the BFF. The rebamipide-induced increase in BFF was sustained at the level of the SNP-induced increase in BFF during the late period of experiment. Rebamipide increased the WMS of skin flaps and prevented the tissue necrosis in comparison with L-NAME. Based on these results, it is concluded that in rabbit skin, UVL irradiation increases the BFF by NO release, and rebamipide exerts a protective effect on the viability of ischemic skin flaps by either or both the increase in BFF by NO release and free radical scavenger effect.

The novel compound KH 3218 was synthesized and evaluated for its ability to inhibit the gastric H$^{＋}$＋ $K^{＋}$ ATPase activity in vitro as well as to lessen gastric acid secretion in vivo. KH 3218 inhibited rabbit gastric H$^{＋}$＋ $K^{＋}$ ATPase in a concentration and time dependent manner. $IC_{50}$/ value was estimated to be about 15 $\mu$M. The inhibition of the H$^{＋}$＋ $K^{＋}$ ATPase by KH 3218 was blocked by sulfhydryl reducing agents, dithiothreitol or $\beta$-mercaptoethanol. The inhibition of the enzyme was not reversible by 50 fold dilution of the incubation mixtures, suggesting the irreversible nature of the inactivation. In the pylorus-ligated rift, KH 3218 reduced the total acid output as compared with the control. In addition, KH 3218 was capable of inhibiting H. pylori urease activity. These data suggest that KH 3218 is a potent inhibitor for H$^{＋}$＋ $K^{＋}$ ATPase activity as well as for gastric acid secretion, and has a potential to be developed as a novel antiulcer agent.

Quercetin and its sugar conjugates are the most abundantly distributed bioflavonoids and represent the largest proportion of flavonols in the plant kingdom. The present study was undertaken to demonstrate the effect of quercetin on the role of reactive oxygen species (ROS) in the development of gastric ulcers in rats. Administration of quercetin in doses of 50, 100 and $200\;mg\;kg^{-1}$ twice daily for 5 days, showed dose dependent significant protection against ethanol (EtOH), aspirin (ASP), cold-restraint stress (CRS) and pylorus ligation (PL) -induced gastric ulcer models and the results were comparable with those elicited by sucralfate. The thiobarbituric acid reactive substances in the stomach mucosa, an index of lipid peroxidation and regulation of plasma corticosterone were significantly increased in CRS-induced gastric ulceration. The queroetin $(100\;mg\;kg^{-1})$ and reduced glutathione effectively inhibited gastric lesions induced by CRS with a significant decrease in the lipid peroxidation and plasma corticosterone. These results indicate that quercetin a bioflavonoid exerts its antiulcer effect in light of free radical scavenging and plasma corticosterone in cold restraint stress ulcers.

Objectives: Based on data from Chinese and Indian traditional herbal medicines, gum resin of Ferula assa-foetida (sometimes referred to asafetida or asafoetida) has several therapeutic applications. The authors of various studies have claimed that asafetida has cytotoxic, antiulcer, anti-neoplasm, anti-cancer, and anti-oxidative effects. In present study, the anti-aging effect of asafetida on senescent human dermal fibroblasts was evaluated. Methods: Senescence was induced in in vitro cultured human dermal fibroblasts (HDFs) through exposure to $H_2O_2$, and the incidence of senescence was recognized by using cytochemical staining for the activity of ${\beta}$-galactosidase. Then, treatment with oleo gum resin of asafetida was started to evaluate its rejuvenating effect. The survival rate of fibroblasts was evaluated by using methyl tetrazolium bromide (MTT) assays. Real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blot assays were performed to evaluate the expressions of apoptotic and anti-apoptotic markers. Results: Our experiments show that asafetida in concentrations ranging from $5{\times}10^{-8}$ to $10^{-7}g/mL$ has revitalizing effects on senescent fibroblasts and significantly reduces the ${\beta}$-galactosidase activity in these cells (P < 0.05). Likewise, treatment at these concentrations increases the proliferation rate of normal fibroblasts (P < 0.05). However, at concentrations higher than $5{\times}10^{-7}g/mL$, asafetida is toxic for cells and induces cell death. Conclusion: The results of this study indicate that asafetida at low concentrations has a rejuvenating effect on senescent fibroblasts whereas at higher concentrations, it has the opposite effect of facilitating cellular apoptosis and death.
