Objective : Juglandis Semen has a function that to invigorate the lung and kidney. And It is commonly used as a supporting agent in the treatment of coughing and bronchitis. This study was performed to investigate the effect of oral administration of Juglandis Semen Extract (JSE) against the experimental asthma induced by ovalbumin. Methods : Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin. It was observed the change of the cell number in the BAL fluid. Concentrations of IL-4, IL-5 in splenoc yte were assessed by ELISA, IgG and IgE from serum were calculated by same method. Results : 1. Number of macrophage in BAL fluid was significantly decreased in JSE group compared with control group, but not eosinophil and lymphocyte. 2. Levels of IgG and IgE in serum were significantly decreased in JSE group compared with control group, respectively. 3. Concentration of IL-4 in culture supernatant of splenocyte was significantly decreased in JSE group compared with control group, but there was no significant in IL-5. Conclusion : We found that the effect of JSE extract in asthma was implicated in reduction of IL4released from Th2 cell, and decreases of IgG and IgE from plasma cell. These findings suggest that JSE can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

This study was undertaken to determine if Juglandis Semen Aquacupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Rats were dehydrated for 24hr and then injected with $5m{\ell}/kg$ of 50% glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received $0.1m{\ell}$ of Ja extraction in both sides of corresponding $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). There were significant decrease of Urine vollume, total protein and phosphate level in Ja-AS as compared with the control group. There were not any significant change of Urine creatinine in Ja-AS as compared with the control group. There were significant decrease of Unine glucose in Ja-AS, Ja-AN as compared with the control group. This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

This study was performed to determine if Juglandis semen extract(JSE) has free radical scavenging and antioxidant activities. Superoxide anion generation by xanthine oxidase/xanthine and in neutrophils activated by phorbol-12, 13-dibutyrate was inhibited by JSE and its effect was dose-dependent. JSE also inhibited generation of $H_2O_2$ induced by glucose oxidase/glucose and in opossum kidney cells treated with antimycin A. JSE exerted a direct $H_2O_2$ scavenging effect. Exposure of opossum kidney cells to 1mM tBHP caused a significant increase in lipid peroxidation, which was prevented by JSE. JSE also prevented tBHP-induced LDH release. These data suggest that JSE has free radical scavenging and antioxidant activities. However, further studies should be carried out to find the active ingredient(s) of JSE that exerts radical scavenging action.

Objectives : Free radical metabolism seems to occupy a remarkably common position in the mechanisms of aging and aging related disease. This study was designed to find out whether Juglandis Semen herbal acupuncture solution (JSHAS) can scavenge Nitric Oxide (NO) or not. Methods : SNAP was used as NO generator. NO concentration was estimated after 2, 6, 12 and 24 hrs in no treatment group, after treatment with Vitamin C or 1, 10, 100 ${\mu}g/ml$ of JSHAS. Results : There was no significant scavenging effect of JSHAS on NO after 2, 6 hrs but significant effect on NO in 10, 100 ${\mu}g/ml$ group. Conclusions : These results suggest that JSHAS has scavenging effect on NO. This study shows that JSHAS can be used for aging related disease and further studies are required to investigate the antioxidative effects of it.

The purpose of this research was to investigate the effects of the administration of Juglandis Semen without inner cortex (JE) or with inner cortex (JEIC) on activity of splenocytes and peritoneal macrophages in BALB/C mice. JE (300 mg/kg, p.o.) did not affect the cell viability of T- and B-lymphocytes in murine splenocytes, but JEIC (300mg/kg, p.o.) increased the cell viability of T- and B-lymphocytes. Furthermore, JE decreased the population of B220$^+$ cells in splenocytes, but JEIC enhanced the population of Thyl$^+$ cells. Also, JEIC enhanced the population of splenic CD4$^+$ cells. JE decreased the production of nitric oxide and the phagocytic activity of peritoneal macrophages, but JEIC increased the production of nitric oxide and the phagocytic activity of peritoneal macrophages. These results suggest that JEIC is more potent than JE against the immune response induced by splenocytes and macrophages.

Objective : The present study was carried out to determine if Juglandis Semen Aquacupuncture(JSA) exerts beneficial effect against the urine concentrating defect induced by glycerol injection in rabbits. Methods : In order to test the effect of JSA, rabbits were acupunctured with $0.5m{\ell}$ of 1%JSA for 7days at both sides of $Sh{\grave{e}}ns{\bar{u}}$(BL23) before the glycerol injection. The other animals were pretreated with an equal volume of saline instead of JSA. Results : The urine flow was reduced, but the urine osmolality was significantly lower than the basal period in glycerol-injected animals, indicating that glycerol causes the urine concentrating defect. The fractional excretion of Na and K was increased in glycerol-treated animals. The Free-water clearance and fractional water excretion(V/GFR) were increased in animals treated with glycerol. Conclusion : These results indicate that glycerol injection resulted an impairment in the urine concentrating ability in rabbits. Such changes were prevented by JSA. JSA may be used as a method to treat and prevent glycerol-induced acute renal failure.

This study was undertaken to determine whether Juglandis Semen (JAS) extract exerts protective effect against oxidant-induced inhibition of $Na^+-pump$ activity in cerebral cortex. $Na^+-pump$ activity was estimated by measuring ouabain-sensitive oxygen consumption. The oxygen consumption significantly inhibited by 1mM t-butylhydroperoxide (tBHP), which was prevented by addition of 2% JAS extract. The oxygen consumption was increased by an increase in $Na^+$ concentration from 5 to 100 mM, $K^+$ concentration from 0.5 to 10 mM, and $Mg^{2+}$ concentration from 0.2 to 5 mM. These changes in ion concentrations did not affect the inhibitory effect of tBHP and protective action of JAS on oxygen consumption. tBHP (l mM) produced a significant increase in lipid peroxidation in cerebral cortex, which was prevented by 2% JAS extraction. These results suggest that JAS exerts protective effect against tBHP-induced inhibition of $Na^+-pump$ activity in the cerebral cortex, probably through action as antioxidant.

Objectives : This study was undertaken to examine whether Juglandis Semen herbal acupuncture (JGA) exerts protective effect against oxidant-induced cell injury in rabbit liver. Methods : The cell damage was estimated by measuring lactate dehydrogenase (LDH) release, and lipid peroxidation was estimated by measuring malondialdehyde (MDA) in rabbit liver slices. Results : t-Butylhydroperoxide (tBHP) caused an increase in LDH release and lipid peroxidation in a dose-dependent manner over concentrations of 0.5-2 mM, which were prevented by addition of 0.05% JGA. The protective effect of JGA was dose-dependent in concentration range of 0.005 to 0.1%. The concentrations of 0.005 and 0.1% JGA completely prevented the LDH release and lipid peroxidation by 1 mM tBHP. When liver tissues were exposed to 1 mM tBHP, alanine aminotransferase (ALT) activity in the medium was significantly increased, which was prevented by 0.05% JGA. tBHP (2 mM) decreased GSH content and the effect was prevented by 0.05% JGA. Conclusion : These results suggest that JGA exerts protective effect against oxidant-induced cell injury by antioxidant action resulting from enhancement of GSH content in the liver.

This study was undertaken to determine Juglandis Semen extraction (JS) has a protective effect against the cell injury caused by oxidants, t-butylhydroperoxide (t-BHP) and $H_{2}O_2$ in rabbit lung slices. Cell injury was estimated by measuring tissue water content and peroxidation of membrane lipids was assessed by measuring malondialdehyde (MDA), an end-product of lipid peroxidation. t-BHP significantly increased water content in lung tissues over concentrations of 2-10 mM, and such effects were prevented by 5% JS. JS exerted the beneficial effect in a dose-dependent manner. $H_{2}O_2$ (100 mM) also increased water content in tissues, which was almost completely prevented by 5% JS. t-BHP induced lipid peroxidation in a dose-dependent fashion in lung tissues over concentrations of 0.5-10 mM. JS significantly reduced t-BHP induced lipid peroxidation and oxidant-independent endogenous lipid peroxidation, and such effects were dose-dependent at concentration of 0.5-10%. JS prevented $H_{2}O_2$ (100 mM)-dependent lipid peroxidation. These results suggest that JS prevents ceil injury induced by oxidants in the lung, and such effects may be attributed to inhibition of lipid peroxidation. The precise mechanisms remains to be explored.
