Influence of Huiyang Shengji Ointment and Its Modified Formulae on Serum Interleukin-1α and Thromboxane B2 in Diabetic Rats with Chronic Skin Ulcers / 中国中医药信息杂志

Objective To observe the influence of Huiyang Shengji Ointment and its modified formulae on interleukin-1 (IL-1α) and thromboxane B2 (TXB2) in diabetic rats with chronic skin ulcers, and explore the mechanism for promoting the healing of ulcer.Methods Six out of 160 rats were randomly selected as a blank group, without any further processing. The remaining rats were made diabetic model and randomly divided into five groups after 2 weeks:1 d, 3 d, 5 d, 7 d and 14 d groups. Then, these groups were further divided into normal group (Vaseline ointments), model group (Vaseline ointments), Huiyang Shengji Ointment group (whole formula Ointment), Wenyang Yiqi group (Yiqi group, modified Wenyang Yiqi formula ointments) and Huoxue Shengji group (Huoxue group, modified Huoxue Shengji formula ointments). Normal group and model group were given Vaseline ointments;whole formula group, Yiqi group and Huoxue group were given corresponding ointment. Normal group used the method of skin excision, while other groups used STZ injection-hydrocortisone interference-skin excision-foreign body embedded preparation of composite factors for chronic skin ulcer model. After the appropriate treatment period, the rats were executed and tested for the contents of IL-1α and TXB2 in serum by enzyme-linked immunosorbent assay of five time points.Results In treatment 3 d, the contents of IL-1α in Yiqi group were significantly higher than the blank group, model group, whole formula group and Huoxue group (P<0.05). In treatment 5 d, the contents of IL-1α in whole formula group were significantly higher than the blank group and model group (P<0.05). In treatment 7 d, the contents of IL-1α in each treatment group were significantly higher than blank group and model group (P<0.05), and the whole formula group was higher than the Yiqi group and Huoxue group. In treatment 14 d, the contents of IL-1α in model group and Huoxue group were lower than the blank group (P<0.05). In treatment 3 d, the contents of TXB2 in normal group and the whole formula group were higher than the blank group (P<0.05). In treatment 5 d, the contents of TXB2 in whole formula group were higher than the blank group and the normal group (P<0.05). In treatment 7 d, the contents of TXB2 in Yiqi group were higher than the blank, the model, the whole formula and Huoxue groups (P<0.05). In treatment 14 d, the contents of TXB2 in Huoxue group were higher than the blank and model group (P<0.05), and the contents of TXB2 in the blank group and normal group was lower than those treatment groups (P<0.05).Conclusion Huiyang Shengji Ointment and its modified formulae could promote inflammation, stimulate secretion of inflammatory cytokines, while Yiqi Wenyang ointments played a more active role in promoting inflammation of the early phase of wound surface.

Effect of zhuhong ointment on renal antioxidant capability in skin ulcer model rats / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effect of repeated administration of Zhuhong ointment on renal antioxidant capability of ulcerous skin in rats, in order to further discuss the mechanism of mercury contained in Zhuhong ointment on the antioxidant capability of kidney in skin ulcer rats.</p><p><b>METHOD</b>Eighty SD rats were randomly divided into eight groups: Zhuhong ointment A, B, C, D, E (1.219, 0.609, 0.305, 0.152, 0.76 g x kg(-1)) groups, the vaseline group, the ulcer model group and the impairment control group. The levels of NAG and RBP of toxicity for early kidney tubular injury and T-AOC, SOD, GSH-PX and GSH in kidney were determined after consecutive administration for 14 days.</p><p><b>RESULT</b>Compared with ulcer model group, the levels of RBP in groups A, B, C and D increased, while the levels of NAG increased only in the group A. The level of T-AOC increased in groups A, B and C. The level of T-SOD increased in the group E, while it dropped down greatly in the group A. The level of GSH-PX increased in groups A, B and C. The content of GSH increased in every dose groups.</p><p><b>CONCLUSION</b>Antioxidant capacity in rats can be increased in a reasonable dose of Zhuhong ointment, but some antioxidant activity can be notably inhibited by with the increase of dose.</p>

Effects of zhuhong ointment on mercury cumulation and renal organization modality in skin-impaired model rat / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effects of Zhuhong ointment on accumulation in the body of mercury and the pathological morphology changes of kidney, via the measurement of related indicators of the skin-impaired model rat.</p><p><b>METHOD</b>Eighty-eight SD rats were randomly divided into the impairment control group, and high-, middle-, low-dose Zhuhong ointment groups. Each group was treated by corresponding methods for 4 weeks, and recovering for 4 weeks. Urinary potein (PRO), pH, Beta N-acetyl aminoglycosidase enzymes (NAG) and beta2-microglobulin (beta2-MG) contents in urine were taken as monitoring indexes, blood urea nitrogen (BUN) and serum creatinine (SCr) in blood and the levels of mercury in urine, blood and kidney were tested, and the pathological morphology changes of kidney were observed.</p><p><b>RESULT</b>After treatment for 4 weeks, compared with impairment control group, the levels of mercury in urine, blood and kidney in every dose group increased significantly (P < 0.01). And the relation exists between toxicity and dose on Zhuhong ointment. After recovery for 4 weeks, the levels of mercury in urine and blood in every dose group restore normal, while the level of mercury in kidney in high- dose group still increased (P < 0.01). The level of NAG increased only in high-dose group. There was no significant difference in NAG contents between Zhuhong ointment groups and the impairment control group (P < 0.05).</p><p><b>CONCLUSION</b>Excess using Zhuhong ointment repeatedly may lead to accumulation of mercury and pathological morphology changes of kidney. So the levels of mercury in the body and related indicators of renal functions should be tested in clinical when long-term using Zhuhong ointment.</p>
