  • In the previous report, E-kong-san, which is usually used for recovering health in traditional medicine, has been shown to decrease cisplatin induced nephrotoxicity in vivo and in vitro. The significant reduction of E-kong-san on the cisplatin induced nephrotoxicity led us to investigate whether the effect of this water extract was a result of triggering antioxidation. In monkey kidney Vero cells, E-kong-san at $5{\sim}10\;mg/ml$ was able to attenuate 2mM cisplatin-stimulated cell death by 46.8% and 31.8%, respectively. E-kong-san showed strong free radical scavengering activities on 1,1-diphenyl-2-picrylhydrazil (DPPH) radical and xanthine/xanthine oxidase (XOD) generated superoxide anion radical $(O_2^{-.})$. We further studied the effects of E-kong-san on lipid peroxidation in rat liver microsomes induced by enzymatic and nonenzymatic methods. Moreover, E-kong-san exhibited significant inhibition on both ascorbic $acid/Fe^{2+}$ and $ADP/NADPH/Fe^{3+}$ induced lipid peroxidation in rat liver microsomes. Based on these results, we suggest that E-kong-san protects the cisplatin induced cytotoxicity by its antioxidative mechanism.

  • In the present study, anti-oxidative and the RMC proliferation inhibitory propeties of 80% ethanol extracts from 63 kinds of traditional medicines were investigated. Inhibitory effects of RMC proliferation were showed that Dalbergia odorifera T. Chen., Melia azedarach Linn$\acute{e}$ and Hydnocarpus anthelmintica Pierre. Among them Hydnocarpus anthelmintica Pierre had the highest anti-oxidative activity ($ORAC_{PE\;value}=1.6$, DPPH = 81.1), but Dalbergia odorifera T. Chen. and Melia azedarach Linn$\acute{e}$ had no effects. These results suggest that the Hydnocarpus anthelmintica Pierre could prevent or protect from kidney disease as antioxidant and anti-proliferative agent for RMC.

  • This study was conducted to assess the chemopreventive effects of chitosan in a rat colon carcinogenesis induced by azoxymethane (AOM). Ninety, 5-week-old, male F344 rats were divided into three groups. The animals in group 1 received subcutaneous injections of 15mg/kg AOM three times for two weeks, then were placed on powdered basal diet containing 2% chitosan for 37 weeks from weeks 3 to 40. The animals in group 2 were given AOM alone. The animals in group 3 were given 2% chitosan without prior carcinogen treatment. All animals were sacrificed at week 12 for quantitative analysis of aberrant crypt foci (ACF) and at week 40 fur analysis of tumor induction. Total numbers of ACF and AC per colon of group 1 were not significantly different from those of group 2. Tumor incidences and multiplicities of small intestine in the group 1 were significantly decreased compared with those of the group 2 (P<0.05). According to pathological diagnoses, adenocarcinoma incidence and multiplicity in the small and large intestine in the group 1 were significantly decreased compared with those of the group 2 (p<0.05). No toxic effects were observed in animals given chitosan in terms of body weights, and liver or kidney histology. These results indicate that chitosan may have a potential as chemopreventive agents of colon carcinogenesis during the postinitiation stage.

  • Brain dopamine systems play a central role in the control of movement, hormone release, and many complex behavior. The action of dopamine at its synapse is terminated predominately by high affinity reuptake into presynaptic terminals by dopamine transporter (DAT). The dopamine transporter(DAT) is membrane protein localized to dopamine-containing nerve terminals and closely related with cocaine abuse, Parkinsonism, and schizophrenia. In present study, the recombinant plasmid pRc/CMV-DAT, constructed by subcloning of a cDNA encoding a bovine DAT into eukaryotic expression vector pRc/CMV, was stably transfected into CV-1 cells(monkey kidney cell line). The DAT activities in the cell lines selected by Geneticin$^{R}$ were determined by measuring the uptake of $[^3H]$-dopamine. The transfected cell lines showed 30-50 fold higher activities than untransfected CV-1 cell line, and this result implies that DAT is well expressed and localized in transfected cells. The transfected cells accumulated $[^3H]$-dopamine in a dose-dependent manner with a $K_{m}$ of 991.6nM. Even though high doses of norepinephrine, epinephrine, serotonin, and choline neurotransmitters inhibited the uptake of $[^3H]$-dopamine, DAT in transfected cell line was proven to be much more specific to dopamine. The psychotropic drugs such as GBR12909, CFT, normifensine, clomipramine, desipramine, and imipramine inhibited significantly the dopamine uptake in tissue culture cells stably transfected with DAT cDNA. Radioactive in situ hybridization was done to map the cellular localization of DAT mRNA-containing cells in the adult rat central nervous system. The strong hybridization signals were detected only in the substantia nigra pars compacta and ventral tegmental area. The restricted anatomical localization of DAT mRNA-containing cells confirms the DAT as a presynaptic marker of dopamine-containing cells in the rat brain.

  • In this study, the effect of verapamil (VER) on cyclosporin A (CsA)-induced nephrotoxicity was investigated in uninephrectomized rats. Male Wistar rats were administered CsA (50 mg/kg/day, p.o.) or VER (0.5 mg/kg/day, i.p.) with CsA (50 mg/kg/day, p.o.) for 20 days. The urinary N-acetyl-$\beta$-D-glucosaminidase (NAG) activity along with BUN, serum creatinine, creatinine clearance (CLcr), body weight, and 24 hr-urine output were measured and histopathologic changes of kidney were evaluated by light and electron microscopy. The results obtained from this study can be summarized as follows: While NAG activity, BUN and serum creatinine was progressively increased and CLcr significantly decreased in CsA group, VER almost signifi-cantly (p<0.05) suppressed and normalized CsA-induced changes in VER+CSA group. While urine output increased until 12th days and thereafter progressively decreased in CsA group, it gradually increased in control and VER+CSA group. While body weight progressively made a gain in control and VER+CSA groups, it significantly (p<0.05) lost in CsA group. On light microscopy, the glomerular hyperemia and proximal convoluted tubular (PCT) dilatation, focal tubular cell vacuolation and necrosis were clearly evident in CsA group, but, were not seen in other groups. Ultrastructural studies revealed thickened glomerular endothelium and basal lamina of capillary, irregular shaped pedicels of podocytes, indistinct slit pores and narrowed bowman's space. The large oval vacuoles with dense debris and phagosome were distributed in apical zone and deformed microvilli and mitochondria were seen in the PCT cell of CsA group. But, glomeruli and PCT cell were relatively preserved in normal apperance in other groups. In conclusion, it is suggested that verapamil has a protective effect on cyclosporine-induced nephrotoxicity in uninephrectomized rats.

  • These experiments were designed to study the influence of protein undernutrition during lactation period(3 wks) or after-weaning period(8 wks) on growth of organs, and on brain and liver composition of the experimental rats. The following experimental groups were studied. Group No. Rats Lactation(3 wks) (Diet of mother rat) After-weaning period(8wks) Rehabilitation Period(17wks) I 8 25% Casein diet 25% Casein diet 25% Casein diet II 8 12% Casein diet 25% Casein diet 25% Casein diet III 8 25% Casein diet 5% Casein diet 25% Casein diet IV 8 12% Casein diet 5% Casein diet 25% Casein diet After the perriod of rehabilitation(17 wks) with 25% casein diet, the following results were obtained. 1. Most of the organs except the spleen could not catch up with the normal group in their weights for the group of protein undernutrition during lactation(3 wks), even after 17 weeks of rehabilitation. For the group of protein undernutrition during after-weaning period(8 wks) brain, lung, heart, spleen and pancreas could catch up with the normal group after rehabilitation. According to this result it is assumed that the growth of brain, lung, heart and pancreas might be developed mostly during lactation and that the growth of liver and kidney might be developed after-weaning period continuously. 2. For the groups of protein underuntrition during lactation period or after-weaning period the amounts of total lipid, cholesterol and phospholipid of brain were lower than those of normal group. Especially, cholesterol level was significantly lower than normal group. And there was also a significant difference in the phospholipid level of the after-weaning(8 wks) deprivation group. 3. The groups of protein undernutrition during lactation or after-weaning period(8 wks) showed lower level of liver nitrogen and higher level of liver fat. Especially, protein undernutriton during lactation gave a greater influence on the lever of liver fat.

  • A biosensor for the measurement of L-glutamine has been constructed by immobilizing the slice of Wistar rat kidney and it's organelle on $NH_3$ gas-sensing electrode. The effects of pH, buffer solution, temperature and thickness of slice were investigated in order to optimize electrode response. The tissue sensor had the linearity in the range of L-glutamine concentration $8.0{\times}10^{-5}{\sim}1.0{\times}10^{-2} M$ with a slope of 53.8 mV/decade in 0.05 M phosphate buffer solution, pH 7.8 at $30^{\circ}C$, and optimum thickness of slice and response time were 30 ${\mu}m$ and 3∼5 min, respectively. The organelle sensor showed the linearity within L-glutamine concentration range of $1.2{\times}10^{-4}{\sim}5.0{\times}10^{-3} M$ with a slope of 54.0 mV/decade in 0.05 M phosphate buffer solution, pH 7.8 at $30^{\circ}C$, and response time was 6∼7 min, respectively. Thus, it is clear that the tissue and organelle sensor will be useful for L-glutamine measurements.

  • The therapeutic effect of tissue cultured root of mountain ginseng (Panax ginseng) (tcMG) on 2,3,7,8-tetrachlorodaibenzo-p-dioxin (TCDD) induced toxicity in rat was investigated. The rats were assigned into three groups (10 rats/group), control, TCDD exposed group and tcMG treated group after TCDD exposed. $50\;{\mu}g/kg$ of TCDD was injected by i.p. for TCDD exposed group and 30 mg/kg of tcMG saponin was administered for 4 weeks by oral gavage for tcMG treated group. The weights of body, spleen, kidney, thymus, testes and epididymides were decreased in the single TCDD treatment. However these organs was significantly recovered by tcMG saponin except thymus (p<0.05). tcMG decreased the level of hepatic demage maker enzymes, AST and ALP. It also lowered total cholesterol and triglyceride. The level of serum triglyceride was significantly decreased in tcMG saponin treated group compared with the control. Histopathological examination revealed morphological change in the liver spleen, thymus and testes of TCDD treated rats. However they were relatively well preserved in the tcMG treatment group. In conclusion, TCDD induced toxicity was some repaired by tcMG. tcMG may be useful for prevention and treatment of TCDD induced toxicity.
