  • In this study, we investigated the anti-inflammatory effects of Lactobacillus rhamnosus fermented black garlic (FBG) in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. FBG did not show cytotoxicity in RAW 264.7 cells at concentrations less than $800{\mu}g/mL$, and cell viability increased with FBG concentration. Nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production as well as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and IL-6 formation decreased in an FBG concentration-dependent manner, in LPS-induced RAW 264.7 cells. Furthermore, activation of LPS-inducible nitric synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor kappa B (NF-${\kappa}B$), and inhibitory kappa B ($I{\kappa}B$) protein expression was effectively inhibited by FBG treatment in LPS-induced RAW 264.7 cells. In contrast, heme oxygenase-1 (HO-1) protein expression significantly increased. These results indicate that the anti-inflammatory activity of FBG was due to activation of NF-${\kappa}B$, inhibition of cytokine production, and expression of iNOS and COX-2. From these results, we expect that FBG could contribute to the prevention and improvement of inflammatory disease.

  • It has been shown that the physical properties of three anti-caking conditioners added garlic powders can be monitored and evaluated by some tests. The test parameters obtained are all quantifiable for powders fundamental properties. It is clear that cellulose powder and calcium carbonate are not attributed to the particle surface improvement effects. When SSA added 2% (w/w) for garilic powder which is improved flow ability and attractive index. Bulk density and compressibility were more sensitive indices to changes occurring in some conditioner added garlic powders.

  • The effect of allicin, the major component of garlic (Allium sativum), on the gene expression profiles of peripheral blood mononuclear cells from healthy donors was analyzed. DNA microarray which can detect expression signal of 862 genes revealed that allicin induced the expression of cytokine, chemokine, and immune-related genes in peripheral blood mononuclear cells. In contrast, allicin repressed the expression of adaptive immune-related genes, which are expressed in T helper 1 Iymphocytes. Simultaneous inhibitory and stimulatory effects of allicin were found on inflammatory cells. It is likely that allicin down-regulated the expression of specific genes that were previously up-regulated in resting cells, suggesting a new mechanism by which they exert positive and negative effect. Considering the broad and renewed interest in allicin, the profiles we describe here will be useful in designing more specific and efficient treatment strategies.

  • This study was designed to investigate the effects of Garlic Jug A Jii, a popular processed food for Korean was given of HCI-ethanol in rats as experimental Model. Oral administration HCI-ethanol to fasted rats produced extensive necrosis in the gastric mucosa. Pretreatment with garlic juice and 3 week stored Garlic Jang A Jii juice prevented such necrosis and the effects were dose-dependent. The effects of garlic Jang A Jii juice comparing with raw garlic juice were reduced but statiscally significant differences were not found. 5 week-stored Garlic Jang A Jii was inhibited the formation of gastric mucosal injury. Comparing with garlic Jug A Jii for 3 weeks, while garlic Jang A Jii juice and 1 : 10 diluted garlic Jang A Jii juice did not show significant shifts but the effects of 1 100 diluted garlic Jang A Jii was decreased. Oral administration of disulfide prevented the gastric mucosa injury whereas sulfhydryl blockers such as N-ethylmaleimie and indomethacin was decreased on gastric mucosa protective effect. The content of diallyl disulfide was 1.41mg% in raw garlic, 0.96mg% in garlic Jang A Jii for 3 weeks. The content of diallyl disulfide was gradually reduced according to the elapse of storage period.

  • Lead poisoning is currently one of the major public health problems in industrialized countries. Several chelating agents have been developed and used to treat the lead poisoning. It was recently proposed that garlic, having a large quantity of S-S compounds, may react readily with lead, producing various sulfur componds, and thus provide curative and protective effects on the lead toxicity. The present study was undertaken to evaluate this possibility in experimental animals. The garlic treatment on rats pre-exposed to lead significantly enhanced urinary excretion of lead at a garlic dose of 500 mg/kg and decreased the bloon level of lead at both 250 and 500 mg/kg doses. The administration of grilic 500mg/kg along with lead significantly alleviated the renal histological alterations induced by lead. These results suggest that garilic has a curative as well as a protective effect against lead poisoning , thus it may act as a chelator of lead.
