Objectives: This study examined whether Lycii Radicis Cortex has an inhibitory effect on inflammatory response through an oxidative stress and advanced glycation endproducts (AGEs)-mediated pathway in streptozotocin (STZ)-induced type 1 diabetic rats. Methods: Lycii Radicis Cortex was orally administered to STZ-induced diabetic rats in doses of 80 or 160 mg/kg body weight/day for 2 weeks, and its effects were compared with those of diabetic control and normal rats. Results: The administration of Lycii Radicis Cortex decreased the elevated serum urea nitrogen and renal reactive oxygen species (ROS), and reduced the increased AGEs in the serum and kidney. The elevated protein expressions of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunits in the kidney of diabetic control rats were significantly decreased after Lycii Radicis Cortex treatments. Moreover, the kidney of diabetic rats exhibited the up-regulation of receptor for AGEs (RAGE) and AGEs-related proteins; however, Lycii Radicis Cortex treatment also significantly reduced those expressions (excepted RAGE). In addition, the diabetic rats exhibited an up-regulation of the expression of proteins related to inflammation in the kidney, but Lycii Radicis Cortex administration reduced significantly the expression of the inflammatory proteins through the nuclear factor-kappa B (NF-${\kappa}B$) and activator protein-1 (AP-1) pathways. Conclusions: This study provides scientific evidence that Lycii Radicis Cortex exerts the antidiabetic effect by inhibiting the expressions of AGEs and NF-${\kappa}B$ in the STZ-induced diabetic rats.

Objectives : The effects of Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex on the change of the HPA-Axis system and the Catecholamic system was investigated. Methods : After performing the Forced Swimming Test(FST), the expressions of corticotropin releasing factor(CRF), c-Fos in the paraventricular nucleus(PVN), and tyrosine hydroxylase(TH) in the ventral tegmental area(VTA) and locus coeruleus(LC) were measured by immunohistochemical method. Results : The duration of immobility in FST was significantly decreased in A 100(Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex, 100mg/kg) and A 400(Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex, 400mg/kg)(p<0.001). The expression of CRF in the PVN was shown the tendency to reduce in A100 and A400. The expression of c-Fos in the PVN was shown the tendency to reduce in A100 and A400. The expression of TH in the VTA was shown the tendency to reduce mildly in A100 and A400. The expression of TH in the LC was significantly reduced in A400(p<0.001). And the dose dependent reduction tendency was shown, respectively. Conclusions : According to the results above mentioned, the immobility, c-Fos and CRF expression was reduced at lower dose and was increased at higher dose. Therefore there is contradictory effects on the HPA Axis system in accordance with the dose. But in the effects on the catecholaminergic system, it significantly reduced the expression of TH in the LC. It was validated that the effect on the catecholaminergic system was ruled by Bupleuri Radix rather than Lycii Radicis Cortex via mainly the noradernergic system.

Immunological activities of the combined-administration of Acanthopanacis Cortex and Lycii Cortex Radicis were examined in BALB/C mice. The 40% ethyl alcohol extract of Acanthopanacis Corter (AE) or the 40% ethyl alcohol extract of Acanthopanacis Coriex and Lycii Cortex Radicis (ALE) were administered p.o. once a day for 7 days, respectively. AE did not affect the viability of thymocytes, but ALE decreased the viability of thymocytes. ALE enhanced the viability of splenocytes increased by AE. Also, AE enhanced the population of cytotoxic T cell in thymocytes, and ALE enhanced the population of helper T cell compared with AE. Furthermore, AE increased the population of $Thy1^+$ cells in splenocytes, and increased the population of splenic $CD4^+$ cells. In addition, ALE enhanced the phagocytic activity which was decreased by AE ALE decreased the production of nitric oxide increased by AE in peritoneal macrophages. These results suggest that ALE enhance an immune-regulative action of AE.
